This high protein ground turkey casserole is a nutritious and satisfying dinner packed with lean turkey, cottage cheese, Greek yogurt, and melted cheese. It delivers over 30g of protein per serving and is ready in about 50 minutes.
Preheat oven to 375 degrees F (190 degrees C). Lightly grease a 9×13 inch baking dish and set aside.
Heat olive oil in a large skillet over medium-high heat. Add ground turkey and cook until fully browned, breaking it apart as it cooks, about 6-8 minutes. Drain all excess fat and liquid thoroughly before continuing.
Add onion, garlic, bell pepper, and mushrooms to the skillet. Cook for 5-7 minutes until vegetables are soft and tender. Season with oregano, basil, garlic powder, salt, and pepper.
In a separate bowl, whisk together cottage cheese, Greek yogurt, and eggs until smooth and well combined.
Spread the turkey and vegetable mixture evenly in the bottom of the prepared baking dish in an even layer.
Pour the cottage cheese mixture evenly over the turkey layer and spread gently to the edges.
Sprinkle shredded cheddar and parmesan cheese evenly over the top.
Bake for 25-30 minutes until the cheese is golden brown and the edges are bubbling. Tent with foil if cheese browns too quickly.
Rest for 5-10 minutes before slicing and serving. Garnish with fresh parsley if desired.
Notes
Drain ground turkey thoroughly after browning to prevent a watery casserole. This is the most common mistake to avoid.
Small curd cottage cheese blends more smoothly with the eggs and yogurt for a better creamy texture.
Assemble up to 24 hours ahead, refrigerate unbaked, and add 5-10 minutes to bake time when cooking from cold.
For extra vegetables, stir fresh spinach or diced zucchini into the turkey mixture before layering.
Ricotta cheese is the best substitute for cottage cheese if needed.
