5 Cheap Proteins That Make Meal Prep Easy (Under $1 Per Serving)

 Can I tell you the single biggest mistake I made when I first started meal prepping on a budget?

I kept buying chicken breast. Every. Single. Week. Boneless, skinless chicken breast — the default protein of every meal prep influencer on the internet. And yes, it's lean, it's versatile, and it's fine. But at $5-7 per pound, it was quietly destroying my grocery budget while I wondered why I couldn't get my weekly spend under control. The turning point came when I started looking at protein differently. Not "what's healthy" but "what gives me the most nutrition for the least money." And what I found completely changed how I cook for my family. These five proteins now make up the backbone of my weekly meal prep. None of them cost more than $1 per serving. All of them are kid-friendly. And together they've helped me cut my grocery bill by over $200 a month. Here they are. 1. Eggs ($0.29 per serving) If eggs aren't already a cornerstone of your meal prep, we need to talk. A dozen eggs costs around $3.50 at most grocery stores. That's 12 servings of protein for less than 30 cents each. Nothing — and I mean nothing — beats that math. But beyond the price, eggs are meal prep magic because of how versatile they are. I use them in at least 4 different ways every single week: Veggie egg muffins: I make a batch of 12 on Sunday, store them in the fridge, and my kids grab them on the way out the door every morning. 45 seconds in the microwave and breakfast is done. Hard boiled eggs: Batch cook 8-10 on Sunday and they last all week in the fridge. Perfect for snacks, quick lunches, or adding protein to a salad. Scrambled eggs for dinner: Don't underestimate breakfast for dinner. Scrambled eggs with some cheese and whatever veggies are in the fridge takes 10 minutes and my kids love it. Fried rice: Day-old rice, frozen peas and carrots, a few eggs scrambled in — this is one of my family's favorite dinners and it costs almost nothing. The only downside to eggs? They don't freeze well once cooked. But with a family to feed, they never last long enough to worry about that anyway. 2. Canned Beans ($0.25 per serving) I know, I know. Beans aren't exactly exciting. But hear me out. A can of black beans or kidney beans costs about $1 and contains 3-4 generous servings. That's 25 cents per serving of protein, fiber, and complex carbs all in one. When you're trying to feed a family on a budget, beans are not a compromise — they're a strategy. My family eats beans at least three times a week and they genuinely don't feel like "budget food" when you prepare them right. Here's how I use them: Black bean taco bowls: Season the beans with cumin, chili powder, and garlic powder. Serve over rice with cheese, sour cream, and salsa. My kids pile their bowls high and ask for seconds. Black bean quesadillas: Mash the beans slightly, mix with shredded cheese, fill a tortilla, and cook until crispy. Done in 15 minutes. Even my pickiest eater cleans his plate. Add them to chili: A pot of chili stretched with two cans of beans feeds my family of 4 for dinner AND gives us lunches for two more days. That's 10 servings from one pot. Soup base: White beans blended into a broth-based soup create a creamy, hearty texture without any cream at all. Genius and cheap. Pro tip: Dried beans are even cheaper than canned — about $1.50 for a pound that yields 6-8 servings. If you have a slow cooker, throw them in overnight and wake up to a week's worth of protein for almost nothing. 3. Lentils ($0.25 per serving) Lentils are the most underrated ingredient in budget meal prep. Full stop. A one-pound bag costs about $1.80 and contains 6-8 servings. They cook in 20-25 minutes with no soaking required. They're high in protein AND fiber. And unlike a lot of budget proteins, they actually absorb flavor beautifully. My go-to lentil recipes for family meal prep: Lentil soup: Sauté onion, carrot, and garlic. Add red lentils, diced tomatoes, chicken broth, cumin, and paprika. Simmer 25 minutes. This soup is so hearty and filling that my husband — a devoted meat eater — never complains when I serve it. It's that good. Lentil bolognese: Cook lentils with diced tomatoes, Italian seasoning, and a splash of red wine vinegar. Serve over pasta. It tastes remarkably like a meat sauce and costs a fraction of the price. Lentil tacos: Season cooked lentils with taco spices and use them exactly like ground beef in tacos. The texture is surprisingly similar and the flavor is spot on. If you've never cooked lentils before, start with red lentils — they're the mildest in flavor and cook the fastest. Your family will never know they're eating a 25-cent protein. 4. Canned Tuna ($0.60 per serving) Canned tuna gets a bad reputation and I think it's completely undeserved. Yes, tuna straight from the can with nothing on it is not exciting. But that's not how you eat it. A 5oz can of tuna costs about $1.20 and contains 2 good servings of lean protein. Here's how I make it work for my family: Tuna pasta salad: Mix tuna with cooked pasta, diced celery, a little mayo, lemon juice, and whatever veggies you have around. This is one of my kids' favorite lunches and it takes 15 minutes to make a batch that feeds everyone for two days. Tuna melts: Tuna mixed with a little mayo and mustard, piled on bread, topped with cheese and toasted under the broiler. My kids think this is a treat. It costs about $1.50 for the whole family. Tuna rice bowls: Tuna over rice with soy sauce, sesame oil, cucumber, and a soft boiled egg. This is my personal favorite quick lunch and it comes together in 5 minutes if you already have rice prepped. One thing I always do: buy tuna packed in water, not oil, and look for the store brand. It's identical in quality and usually 30-40 cents cheaper per can. 5. Chicken Thighs ($0.75 per serving) Okay, I said I moved away from chicken breast — but I never moved away from chicken entirely. I just switched to thighs. Bone-in chicken thighs cost about $2 per pound compared to $5-7 for boneless skinless breast. They're juicier, more flavorful, harder to overcook, and honestly more forgiving for beginner meal preppers. Three pounds of chicken thighs costs about $6 and feeds my family of 4 for dinner with leftovers for lunch the next day. That's 8 servings for $6 — or 75 cents per serving. My favorite ways to prep chicken thighs for the week: Sheet pan roasted: Season with garlic powder, paprika, Italian seasoning, salt and pepper. Roast at 425F for 35-40 minutes. The skin gets crispy, the meat stays juicy, and the whole thing is completely hands off. Slow cooker shredded chicken: Put chicken thighs in the slow cooker with a can of diced tomatoes and taco seasoning in the morning. Shred by dinner. Use in tacos, burritos, rice bowls, quesadillas — the possibilities are endless. Simple pan sauce chicken: Brown thighs in a skillet, make a quick pan sauce with chicken broth, garlic, and lemon, and serve over rice. This is a 30-minute dinner that tastes like it took much longer. The secret to chicken thighs is not to overthink them. Season generously, cook until the internal temperature hits 165F, and they will be delicious every single time.
