There is something wonderfully satisfying about a good rosti. You get those little strands of vegetable that turn golden and crisp around the edges, while the middle stays tender and soft enough to break apart with a fork. With sweet potato, the result is even more interesting because its natural sweetness becomes deeper as it cooks, giving the rosti a warm, almost caramelized flavor without needing much extra seasoning.
This version is the kind of dish that can easily move between breakfast, brunch, lunch, and a light dinner. It feels substantial enough to serve as the main part of a meal, but the toppings keep it from becoming too heavy. The combination of warm sweet potato, roasted tomatoes, creamy avocado, and fresh baby rocket gives you several completely different textures on the same plate.
The tomatoes are especially good here because they bring a little acidity to balance the sweetness of the sweet potato. As they roast, they become softer and juicier, and their natural flavor intensifies. Some will stay plump while others will wrinkle and collapse slightly, releasing their juices over the plate. That contrast is exactly what the rosti needs. 🍠🍅✨
Avocado adds another layer of softness, but in a completely different way. It is cool, buttery, and rich, so a few slices placed over the warm rosti make each bite feel more indulgent. Then the baby rocket cuts through that richness with its fresh, peppery flavor. It is a small addition, but it keeps the whole dish feeling bright.
I also like the fact that the vegetables don’t need to be hidden inside a complicated mixture. You can actually see what you’re eating. Golden strands of sweet potato form the base, bright tomatoes sit over the top, creamy avocado adds color, and fresh rocket finishes everything.
That makes it a particularly good dish for serving at the table rather than treating it as something that has to be plated with absolute precision. You can place the rosti on a large platter, scatter the toppings over it, and let everyone take a portion.
🍠 What makes this combination work so well:
- Sweet potato develops a lovely golden, naturally sweet flavor as it bakes.
- Onion adds savory depth and helps balance the sweetness.
- Roasted tomatoes bring juicy texture and gentle acidity.
- Avocado adds cool, creamy richness.
- Baby rocket provides freshness and a slightly peppery finish.
- The contrast between crisp edges and soft toppings makes every bite interesting.
The preparation is also fairly straightforward. The sweet potato and onion are grated, then squeezed well to remove excess moisture before being spread onto a baking tray. This step is worth taking seriously because too much moisture can prevent the rosti from becoming properly golden.
Once the mixture is in the oven, you have time to prepare the tomatoes and get the toppings ready. The tomatoes roast until tender and juicy, while the avocado can simply be sliced and the rocket kept ready for the final assembly.
There is no need to make the rosti perfectly round, either. A slightly rustic shape actually suits the dish. What matters more is keeping the layer even enough that the edges have a chance to become golden while the center stays tender.
And when it comes out of the oven, resist the urge to immediately cover every inch with toppings. Leave some of those golden edges visible. They’re one of the best parts.
Serve it warm, pile the roasted tomatoes and avocado over the top, scatter generously with baby rocket, and bring it straight to the table.
It is colorful, comforting, and just a little bit different from the usual breakfast or brunch plate. 🍠🍅🥑✨
Why sweet potato works so well in a rosti 🍠
Sweet potato brings something slightly different to a traditional rosti. It has a naturally sweet, earthy flavor and a softer texture once cooked, which makes the finished dish feel a little more tender and substantial.
The important part is getting rid of as much moisture as possible before baking. Freshly grated sweet potato contains quite a bit of liquid, and the onion adds moisture too. If you simply grate everything and spread it straight onto the tray, the mixture can steam rather than develop those lovely golden edges.
A good squeeze makes a noticeable difference.
After grating the sweet potato and onion, place the mixture in a colander and use your hands to press out as much liquid as you can. You don’t need to make it completely dry, but the mixture should feel considerably lighter and less wet before it goes onto the baking tray.
Then comes the spreading.
You want an even layer, but don’t flatten the mixture too firmly. Leaving a little air between the strands helps the edges brown while the middle stays tender. The result should be a rosti that has enough structure to serve in portions but still feels soft and naturally rustic.
| Ingredient | What it adds | Texture | Flavor |
|---|---|---|---|
| Sweet potato | Main rosti base | Tender with golden edges | Naturally sweet and earthy |
| Brown onion | Savory depth | Soft and delicate | Mild and aromatic |
| Cherry tomatoes | Juiciness and acidity | Soft and collapsed | Sweet and tangy |
| Avocado | Creaminess | Smooth and buttery | Mild and rich |
| Baby rocket | Freshness | Tender with a slight bite | Peppery and green |
The beauty of this combination is that none of the toppings needs to be complicated. The sweet potato already has plenty of character, so the tomatoes, avocado, and rocket simply add different textures and flavors around it.
🍠 A few little details help with the rosti:
- Grate the sweet potato and onion fairly coarsely.
- Squeeze out as much liquid as possible.
- Spread the mixture evenly across the tray.
- Don’t press the grated mixture down too firmly.
- Give the rosti enough space to brown rather than steam.
- Season the mixture well before baking.
The edges are worth watching as the rosti cooks. That’s where you’ll start to see the first golden color developing, while the center will remain softer. Once the whole surface has taken on a light golden appearance, it is ready for the toppings.
And honestly, those slightly uneven edges are part of the charm. You don’t need every strand of sweet potato to be perfectly arranged. A homemade rosti should look like something you actually cooked, not something that was assembled with tweezers. 😄
Roasted tomatoes make the plate come alive 🍅✨
While the sweet potato rosti is baking, the tomatoes can quietly do their own thing in the oven. This is one of those small steps that makes a surprisingly big difference.
Cherry tomatoes already have plenty of sweetness, but roasting concentrates it. As the heat works on them, the skins begin to wrinkle, the tomatoes soften, and their juices become more intense. Some may stay almost whole while others collapse more dramatically, and that variation makes them especially nice spooned over the rosti.
You don’t want them completely dried out.
The ideal tomatoes should still be juicy enough to release some of their warm juices over the sweet potato when you serve them. Those juices mingle with the crisp edges and softer center of the rosti, giving the whole dish another layer of flavor.
A light coating of olive oil and some seasoning is all they really need. There is no reason to cover them in herbs or complicated sauces. Let the roasting do the work.
Meanwhile, the avocado brings the opposite texture. It is cool, creamy, and smooth against the warm vegetables, so adding it just before serving keeps that contrast noticeable.
Baby rocket finishes everything with its peppery freshness. It doesn’t need to be cooked. Just scatter it over the warm rosti with the tomatoes and avocado, season lightly, and bring the whole thing to the table.
🍅 For the best roasted tomatoes:
- Use ripe vine-ripened cherry tomatoes.
- Keep them in a single layer on the tray.
- Coat them lightly with olive oil.
- Season before roasting.
- Roast until they begin to soften and collapse.
- Don’t let them dry out completely.
- Spoon them over the rosti while still warm.
There is something particularly nice about seeing the finished plate come together. The sweet potato gives you those warm golden tones, the tomatoes add bright red, the avocado brings creamy green, and the rocket adds a darker fresh note.
It looks colorful without needing elaborate decoration.
And once you cut into the rosti and get a little bit of everything on your fork, the balance becomes obvious: warm sweet potato, juicy tomato, creamy avocado, and peppery rocket.
That’s a pretty good reason to make breakfast for dinner, if you ask me. 🍠🍅🥑
Sweet potato rosti with roast tomatoes recipe 🍠🍅
This sweet potato rosti is one of those dishes that looks beautifully simple on the plate, but has plenty going on once you take a bite. The grated sweet potato becomes golden and lightly crisp around the edges while staying tender in the middle, with grated onion adding a gentle savory flavor underneath all that natural sweetness.
The roasted tomatoes bring a completely different texture. They become soft, juicy, and slightly caramelized in the oven, with their warm juices soaking into parts of the rosti as you serve it. That little bit of acidity is especially welcome alongside the sweet potato, keeping the dish from feeling too rich or sweet.
Then there is the avocado, which adds a cool, creamy contrast to all those warm ingredients. I like cutting it into generous slices rather than mashing it, so you get those soft pieces alongside the crisp edges of the rosti. Baby rocket finishes everything with a fresh, slightly peppery bite.
It is a lovely combination for breakfast or brunch, but it doesn’t really need to stay in the breakfast category. Serve it for lunch with a simple salad, make it part of a relaxed weekend table, or put a large rosti in the middle of the table and let everyone help themselves.
The preparation is also pleasantly straightforward. Most of the work is simply grating the vegetables, squeezing out the excess moisture, and spreading the mixture onto a baking tray. Once it goes into the oven, the sweet potato develops its golden edges while the tomatoes roast alongside it.
And that golden edge is worth waiting for. The slightly crisp strands around the outside give the softer center some texture, while the toppings bring their own contrast with every bite.
Ingredients
For the sweet potato rosti
- 2 large sweet potatoes, peeled and coarsely grated
- 1 brown onion, coarsely grated
- 2 tablespoons olive oil
- Salt, to taste
- Freshly ground black pepper, to taste
For the roasted tomatoes

- Freshly ground black pepper, to taste
For serving
- 1 large avocado, sliced
- 1 bag baby rocket

Instructions
- Prepare the sweet potato.
Peel the sweet potatoes and coarsely grate them. Grate the brown onion as well and combine both in a large bowl. - Remove the excess moisture.
Transfer the grated sweet potato and onion to a colander and squeeze firmly with your hands to remove as much liquid as possible. This step is important for getting a nicely browned rosti rather than a soft, steamed texture. - Season the mixture.
Return the squeezed sweet potato and onion to the bowl. Add the olive oil, salt, and freshly ground black pepper. Toss everything together until evenly seasoned. - Prepare the rosti.
Preheat the oven and line a large baking tray with baking paper. Spread the sweet potato mixture over the tray in an even layer, keeping it loose rather than pressing it down too firmly. - Prepare the tomatoes.
Place the cherry tomatoes on a separate baking tray or in a small roasting dish. Drizzle with olive oil and season with salt and black pepper. - Bake the vegetables.
Place both trays in the oven. Cook until the sweet potato rosti is golden and lightly crisp around the edges and the tomatoes are softened, juicy, and beginning to wrinkle. Keep an eye on the rosti toward the end so the edges don’t become too dark. - Prepare the toppings.
While everything is roasting, slice the avocado and have the baby rocket ready. Keep the toppings chilled until you’re ready to assemble. - Assemble the rosti.
Remove the golden rosti from the oven and allow it to stand briefly so it becomes easier to portion. Arrange pieces on serving plates and spoon the warm roasted tomatoes over the top. - Add the avocado and rocket.
Arrange the avocado slices over the rosti and scatter generously with baby rocket. Finish with a small drizzle of olive oil and a little freshly ground black pepper. - Serve warm.
Bring the rosti to the table while the sweet potato and tomatoes are still warm, with the creamy avocado and fresh rocket providing contrast. 🍠🍅🥑
Helpful tips 💡
- Squeeze the grated sweet potato and onion very well before baking.
- Don’t make the rosti layer too thick, or the center may stay overly soft.
- Leave the mixture slightly loose so the edges can become crisp.
- Roast the tomatoes until juicy and lightly collapsed rather than completely dry.
- Add avocado and rocket just before serving.
- Keep some golden rosti edges visible when adding the toppings.
- Serve immediately for the best contrast between crisp, warm rosti and fresh toppings.
The finished plate should have golden sweet potato edges, tender roasted tomatoes, creamy avocado, and fresh peppery rocket all working together. It’s simple enough for a relaxed brunch but colorful enough to put in the middle of the table when you’re feeding guests. 🍠🍅🥑✨
How to serve sweet potato rosti 🍠🍅🥑
This sweet potato rosti is substantial enough to be the centerpiece of a relaxed breakfast or brunch, but the fresh toppings keep it from feeling too heavy. I like serving it while the rosti is still warm, when the edges have that lovely golden crispness and the center is soft enough to break apart easily with a fork.
The roasted tomatoes should go on while they’re still warm too. Their juices naturally run into the sweet potato, adding a little acidity and extra moisture without making the rosti soggy. Then add the avocado at the last moment so it keeps its cool, creamy texture rather than warming too much.
Baby rocket is best scattered over everything just before serving. Its slightly peppery flavor gives the dish a fresh finish and balances the natural sweetness of the sweet potato and roasted tomatoes.
For brunch, you really don’t need to build an enormous spread around it. A pot of coffee, some fresh fruit, and perhaps a simple green salad are enough. The rosti already gives you plenty of substance, while the toppings make it feel colorful and complete.
For a larger table, serve the whole rosti on a large platter and arrange the tomatoes, avocado, and rocket over the top just before bringing it out. That creates a generous centerpiece and means everyone can take the pieces with the crispest edges.
🍅 A few easy serving ideas:
- Serve the rosti whole on a large platter.
- Cut it into generous wedges for sharing.
- Add roasted tomatoes while they’re still warm.
- Arrange avocado slices over the top just before serving.
- Scatter baby rocket generously over everything.
- Finish with freshly ground black pepper and olive oil.
- Add a simple green salad for extra freshness.
- Serve with lemon wedges if you want a brighter finish.
Don’t worry about making the toppings perfectly symmetrical. Let a few tomatoes tumble toward the edges, leave plenty of golden rosti visible, and scatter the rocket naturally. That slightly relaxed presentation makes the dish feel more inviting.
If you’re serving individual portions, try to give everyone a little of each topping rather than piling everything into one area. The best bite has some crisp sweet potato, a juicy tomato, creamy avocado, and a little peppery rocket together.
Easy ways to make it your own 🌿🍠
Once you’ve made the basic rosti, there are plenty of easy ways to change it depending on the season or what you already have in the kitchen. Sweet potato has a naturally mellow flavor, so it gives you plenty of room to experiment without losing the character of the dish.
The toppings are probably the easiest place to start. Avocado can be paired with a spoonful of thick yoghurt for a creamy, tangy contrast, while rocket can be replaced with baby spinach, watercress, or mixed leaves. If you’re after more crunch, toasted pumpkin seeds or sunflower seeds are a simple addition.
The tomatoes can change too. Cherry tomatoes are convenient because they roast quickly and become beautifully juicy, but larger tomatoes cut into wedges work just as well. You could roast them with a few cloves of garlic, a little fresh thyme, or a pinch of chilli flakes if you want a more savory and aromatic topping.
🌿 A few variations worth trying:
- Add roasted garlic to the tomatoes.
- Finish with fresh parsley, coriander, or thyme.
- Replace rocket with baby spinach or watercress.
- Add thick yoghurt alongside the avocado.
- Scatter toasted pumpkin or sunflower seeds over the top.
- Add fresh chilli or chilli flakes for some heat.
- Use mixed-color cherry tomatoes for a brighter presentation.
- Finish with a squeeze of lemon.
- Add a little crumbled feta for a salty contrast.
You can also make small changes to the rosti itself. A little extra black pepper works beautifully with the sweetness of the potato, while fresh herbs can give the mixture a more savory character. Just remember that the grated sweet potato needs to stay relatively dry, so avoid adding vegetables or ingredients that release a lot of water.
If you’re cooking for a group, another fun option is to make smaller individual rostis rather than one large one. They will have more exposed edges, which means more of that golden, crispy texture for everyone. They also look lovely arranged together on a large serving platter.
And you don’t have to decide on just one version.
Make the classic tomato and avocado combination for most of the table, then add chilli or seeds to a few portions for anyone who wants something a little different.
The best variations are usually the uncomplicated ones. One extra herb, a different leafy green, a handful of seeds, or a sharper squeeze of lemon can be enough to make the dish feel completely new.
A golden plate worth slowing down for 🍠🍅✨
There is something especially satisfying about bringing a warm rosti to the table when the edges are still golden and the roasted tomatoes are still glistening. It has that wonderful homemade quality where you can immediately see what you’re eating, but the finished plate still feels special enough for a leisurely weekend meal.
The colors alone make it inviting. Golden strands of sweet potato form the base, bright red tomatoes sit over the top, creamy green avocado adds richness, and fresh rocket gives everything a darker, peppery finish. You don’t need elaborate decoration because the ingredients naturally make the plate look beautiful.
And then there is the texture.
The outer strands of sweet potato should have a little crispness, while the center remains tender. The roasted tomatoes become soft enough to release their juices, the avocado adds a smooth and buttery bite, and the rocket stays fresh and slightly crisp. It is a simple combination, but there is enough contrast to keep every forkful interesting.
🍠 This rosti is especially lovely for:
- Slow weekend breakfasts.
- Relaxed brunches with friends.
- Light family lunches.
- Outdoor summer meals.
- Meat-free dinners.
- Casual gatherings.
- Breakfast-for-dinner evenings.
- A colorful dish for a shared table.
If you’re cooking for guests, most of the preparation can happen before everyone sits down. Grate and squeeze the sweet potato, prepare the tomatoes, slice the avocado, and have the rocket ready. Once the rosti is baking, the kitchen becomes much less hectic.
For a bigger gathering, you can even put the toppings into small bowls and let everyone build their own portion. Keep the roasted tomatoes warm, place the avocado and rocket alongside them, and let guests choose how generously they want to top their rosti.
That makes the meal feel relaxed rather than overly formal.
And honestly, this is exactly the sort of food that benefits from being eaten slowly. You get that first crisp bite of sweet potato, then the juicy tomato, creamy avocado, and fresh rocket. The flavors are simple, but they complement one another so naturally that there is no need for a complicated sauce or a dozen additional ingredients.
Some meals need a lot of effort to feel special.
This one mostly needs good ingredients, a little patience while the rosti turns golden, and enough time to sit down and actually enjoy it.
Bring the platter to the table while everything is warm, let everyone serve themselves, and don’t be surprised if the crispest edges disappear first. 🍠🍅🥑✨
