Eating healthy doesn’t have to drain your wallet. In fact, some of the most affordable foods are also rich in protein, keeping you full and energized without the hefty price tag. From pantry staples like beans and lentils to versatile eggs and nutrient-packed canned fish, you can fuel your body with protein for less than a dollar per serving.
This guide highlights 10 budget-friendly protein sources that prove nutritious meals don’t need to be expensive. Whether you’re meal-prepping for the week, feeding a family, or simply trying to stretch your grocery budget, these options make it easier to eat smart while saving money.
Pinto Beans
Price: ~$0.30 per ½ cup (about $3 per can)
Pinto beans are one of the most affordable protein powerhouses you can keep in your pantry. Just half a cup offers a hearty dose of protein and fiber, keeping you full and energized. They’re also incredibly versatile—perfect for turning into creamy refried beans, tossing into soups, bulking up salads, or stuffing into burritos.
At restaurants, refried beans may feel like a treat, but making them at home is as simple as simmering canned pinto beans with garlic and spices, then mashing to your preferred texture. Affordable, filling, and nutrient-rich, pinto beans prove that healthy eating on a budget can also be delicious.
Eggs
Price: ~$0.19 per egg (about $3.50 per dozen)
Eggs are one of the most affordable and complete sources of protein you’ll ever find. Each egg contains about 6 grams of high-quality protein along with essential amino acids, healthy fats, and key vitamins like B12, D, and choline—nutrients that support energy, brain function, and overall health. Despite their small size, eggs deliver a nutrient punch that rivals much more expensive protein foods.
Their biggest strength, however, is versatility. In just minutes, you can scramble eggs with seasonal vegetables for a quick breakfast, whip them into an omelet or frittata for lunch, or bake them into casseroles for a hearty dinner. They’re also the secret star in countless baked goods, lending structure, flavor, and richness. And when creativity runs low? Simply top any dish—grain bowls, noodles, even leftover veggies—with a fried or poached egg to instantly make it more filling and satisfying.
From busy mornings to family dinners, eggs are proof that eating healthy and on budget doesn’t have to mean boring. At less than 20 cents per egg, they’re an unbeatable staple for any kitchen.
Chicken Breasts
Price: ~$0.75 per 4-ounce portion (about $2.99 per pound)
Chicken breasts are a budget-friendly source of lean, high-quality protein, with a 4-ounce serving delivering around 26 grams of protein and very little fat. They’re a go-to option for anyone looking to eat healthy without overspending, especially compared to pricier cuts of meat or fast-food alternatives.
Beyond being economical, chicken breasts are endlessly adaptable. You can season and roast them for simple weeknight dinners, slice them into strips for stir-fries, or grill and layer them into sandwiches or wraps. They’re also perfect for global-inspired dishes—think Greek-style gyros with cool tzatziki, spicy chicken tacos, or a comforting chicken and veggie soup.
For meal preppers, chicken breasts are a lifesaver: Cook a batch at the start of the week, and you’ll have a versatile protein ready to toss into salads, grain bowls, or pasta dishes. With their mild flavor and quick cooking time, they’re the blank canvas of healthy, affordable cooking.
At less than a dollar per serving, chicken breasts prove you don’t need to sacrifice flavor, variety, or nutrition to keep your grocery bill in check.
Lentils
Price: ~$0.12 per ½ cup (about $1.50 per pound, dry in bulk)
Lentils are one of the most underrated pantry staples—cheap, versatile, and packed with nutrition. A half-cup serving of cooked lentils contains around 9 grams of protein, plus a hefty dose of fiber, iron, and folate, making them not only filling but also heart-healthy. What’s more, pound for pound, lentils actually provide more protein than beef, yet cost only a fraction of the price.
Their mild, earthy flavor allows them to blend seamlessly into a wide range of dishes. You can simmer them into soups and stews, stir them into aromatic curries, or even use them as a stand-in for ground beef in classics like Bolognese sauce, sloppy joes, or homemade veggie burgers. They cook faster than most dried beans—often in 20 to 30 minutes—so they’re perfect for quick weeknight meals.
Beyond protein, lentils are rich in antioxidants and plant compounds that support long-term health. Swapping in lentils a few times a week is a budget-friendly way to cut back on red meat while still enjoying hearty, satisfying meals.
For anyone balancing nutrition and cost, lentils are proof that humble ingredients can deliver big on both value and flavor.
Tofu
Price: ~$0.20 per ounce (about $3 per pound)
Tofu is a plant-based protein superstar that’s as affordable as it is versatile. A single serving provides around 10 grams of protein with minimal fat, making it a smart choice for vegetarians, vegans, and meat-eaters who want to balance their diets. Since it’s made from soybeans, tofu also contains all nine essential amino acids, which makes it a complete protein source—something not all plant-based foods can claim.
What makes tofu shine is its adaptability. Its mild flavor allows it to soak up marinades, sauces, and spices, transforming it into whatever your dish needs. Extra-firm tofu can be cubed and pan-fried until golden and crispy, tossed into stir-fries, or baked for a chewy, savory bite. Crumble it and sauté with spices to mimic scrambled eggs for breakfast, or season it with taco spices for a hearty plant-based filling. Silken tofu, on the other hand, blends smoothly into soups, creamy dressings, or even fruit smoothies for a protein boost without altering the flavor.
Beyond protein, tofu is also a source of calcium, iron, and isoflavones—plant compounds linked to heart health and bone strength. At just $3 per pound, it’s one of the most cost-effective ways to add nutrition, satiety, and variety to your meals.
Pumpkin Seeds
Price: ~$0.50 per ounce (about $6 per pound)
Pumpkin seeds, often called pepitas, are one of the most nutrient-dense snacks you can buy on a budget. Just a small handful (about 1 ounce) packs around 7 grams of protein, making them an excellent plant-based protein source. Beyond protein, they’re loaded with essential minerals like magnesium, zinc, and iron, which support everything from energy production to immune health and strong bones.
These tiny seeds are incredibly versatile in the kitchen. Sprinkle them over salads for a crunchy boost, stir them into oatmeal or yogurt for extra texture, or toss them into soups as a garnish. They can also be roasted with your favorite spices—smoky paprika, cinnamon, or chili powder—for a satisfying, savory-sweet snack that rivals chips or crackers. Ground pumpkin seeds are even used in traditional Mexican sauces, like mole, adding a rich, nutty depth of flavor.
With their balance of protein, healthy fats, and micronutrients, pumpkin seeds are more than just a garnish—they’re a powerhouse ingredient that deserves a regular spot in your pantry. At about 50 cents per ounce, they’re an affordable way to make everyday meals more nourishing.
Oats
Price: ~$1 per pound (in bulk)
Oats are one of the most affordable and nutritious staples you can add to your diet. A single serving delivers about 5 grams of protein, along with a generous amount of fiber—particularly beta-glucan, a soluble fiber shown to support heart health and help lower cholesterol. Naturally low in fat and rich in essential minerals like manganese, phosphorus, and magnesium, oats prove that whole grains can be both budget-friendly and nutrient-dense.
While oatmeal is the classic go-to, oats are far from boring. Overnight oats are a convenient make-ahead breakfast, easily customized with fruits, nuts, or yogurt. For something different, oats can be baked into muffins or granola bars, blended into smoothies for extra creaminess, or even used in savory dishes like veggie burgers or risottos. Steel-cut, rolled, or instant—all varieties retain their nutrient profile, though steel-cut and rolled tend to offer a heartier texture.
Because they’re filling, versatile, and cost just about $1 per pound in bulk, oats are one of the smartest investments for anyone trying to eat healthy on a budget. They stretch far, store well, and can adapt to nearly any flavor profile, sweet or savory.
Canned Tuna
Price: ~$0.30 per ounce (about $1.50 per 5-ounce can)
Canned tuna is one of the most cost-effective sources of lean protein and healthy fats you can stock in your pantry. A single can packs around 20–25 grams of protein, along with omega-3 fatty acids that support heart, brain, and joint health. It’s shelf-stable, easy to store, and ready to use straight from the can—making it an ideal option for quick, budget-friendly meals.
What makes tuna especially appealing is its versatility. Classic tuna salad gets a healthy upgrade when mixed with Greek yogurt or hummus instead of heavy mayo. It also works beautifully tossed into pasta, folded into grain bowls, layered in sandwiches or lettuce wraps, or mixed with beans and veggies for a protein-rich salad. For a warm option, canned tuna can be baked into casseroles or stuffed into bell peppers for a hearty lunch or dinner.
Since it’s both filling and nutrient-dense, tuna is a lifesaver for busy weeks when you need meals that are cheap, healthy, and fast. And with most cans costing less than $2, it’s proof that eating well on a budget doesn’t have to be complicated.
Black Beans
Price: ~$0.30 per ½ cup (about $1.50 per can)
Black beans may look humble, but they’re nutritional powerhouses at a bargain price. A half-cup serving delivers around 7–8 grams of protein, plus a generous helping of fiber that supports digestion and helps keep you full for hours. They’re also packed with essential nutrients like calcium, potassium, magnesium, and folate—key for heart health, bone strength, and energy metabolism.
One of the biggest perks of black beans is their antioxidant content. Their dark color comes from anthocyanins, the same plant compounds found in blueberries, which may help protect against cell damage. Cooking dry beans at home can even preserve more of these antioxidants while costing less than canned versions, making them one of the most budget-friendly staples you can buy.
In the kitchen, black beans are endlessly versatile. Simmer them into a rich, smoky soup, mash them into tacos or burritos, fold them into salads or grain bowls, or blend them into dips and spreads. They’re also a favorite base for vegetarian burgers, offering a hearty texture and earthy flavor.
Affordable, filling, and deeply nutritious, black beans prove that you don’t need to spend big to eat well.
Whey Protein
Price: ~$0.75 per scoop (about $40 per 3-pound container)
Whey protein is one of the most efficient and convenient ways to boost your daily protein intake, especially if you’re active, looking to build muscle, or simply need a quick, filling option. One scoop typically contains 20–25 grams of high-quality protein, complete with all the essential amino acids your body needs for muscle repair, energy, and overall health.
Beyond fitness shakes, whey protein is incredibly versatile. Blend it into smoothies for a creamy, nutrient-packed breakfast, stir it into oatmeal or yogurt for extra staying power, or even bake it into pancakes, muffins, or brownies to give your treats a protein boost. Because it mixes easily, it adapts well to both sweet and savory recipes without overpowering flavor.
Although it comes with an upfront cost, whey protein stretches far—a single container can last for weeks and provide dozens of servings at under a dollar each. For anyone balancing a busy lifestyle with health goals, it’s a convenient, budget-friendly way to make sure you’re meeting your protein needs.
