You’re trying to eat more protein.
But you’re tired of dry chicken breasts, chalky shakes, and sad salads that leave you hungry an hour later.
What if you could have a rich, comforting, cheesy casserole—packed with 30+ grams of protein per serving—that tastes like a hug, not a punishment?
Good news: you can. And it’s easier than ordering takeout.
In 2025, high-protein eating isn’t just for bodybuilders. According to the International Food Information Council, over 45% of U.S. adults are actively seeking more protein in their meals—for sustained energy, muscle maintenance, blood sugar balance, and staying full longer.
But here’s the catch: most “high-protein” recipes taste like cardboard. This one doesn’t.
This high-protein dinner casserole uses real food—lean ground turkey, cottage cheese, eggs, and Greek yogurt—to deliver deep flavor and serious nutrition in one bubbling dish.
Why This Casserole Works When Others Fail
Most high-protein meals miss the mark because they focus on quantity over quality. They pile on protein powder or skip fat entirely, leaving you unsatisfied.
This casserole is different. It’s built on whole-food protein sources that also bring richness and texture:
- Lean ground turkey or beef: 22g protein per pound
- Cottage cheese: 25g protein per cup (and blends into creamy ricotta-like filling)
- Greek yogurt: 17g protein per cup (replaces sour cream without tang overload)
- Eggs: 6g protein each (binds and adds richness)
- Cheese: Because flavor matters—and it’s protein too
Together, they create a casserole that’s hearty, satisfying, and actually delicious.

Pro Tips From Someone Who’s Made This Weekly
- Blend the cottage cheese. It eliminates lumps and creates a silky, ricotta-like texture.
- Use whole-milk dairy if tolerated. Full-fat versions are more satisfying and prevent dryness.
- Add hidden veggies: Stir 2 cups chopped spinach (squeezed dry) into the cottage cheese mix.
- Boost flavor: Add a splash of balsamic vinegar to the meat sauce—it deepens umami without sugar.
- Make it ahead: Assemble unbaked, cover, and refrigerate up to 24 hours. Add 10 minutes to bake time.
Top 5 FAQs People Actually Search For
1. Can I use chicken instead of turkey?
Yes! Use ground chicken or shredded rotisserie chicken. Just add 1 tbsp olive oil when cooking—it’s leaner.
2. Is cottage cheese really a good ricotta substitute?
Yes—if blended. It’s higher in protein, lower in fat, and takes on flavors beautifully.
3. Can I make it vegetarian?
Absolutely. Swap meat for lentils or plant-based crumbles. Add smoked paprika for depth.
4. How do I keep it from being dry?
Use enough sauce (3+ cups total), don’t skip the Greek yogurt, and always rest after baking.
5. Can I freeze high-protein casserole?
Yes! Cool completely, wrap tightly, and freeze up to 3 months. Thaw overnight, then bake at 375°F for 30–35 minutes.
