10 High-Protein Casserole Recipes for Filling Simple Dinners

Casseroles make weeknight dinners simple and satisfying. These recipes focus on high protein ingredients to keep meals filling. You will find options that use everyday items from your pantry or fridge. They are straightforward to prepare and good for leftovers too.

Helpful Tips Before You Start

These tips will help you build casseroles that stay high in protein and simple to assemble on busy nights.

Add cottage cheese or Greek yogurt

Stir in a cup of low-fat cottage cheese or Greek yogurt to boost protein without changing the flavor much. Both blend smoothly into sauces and keep the texture creamy.

Cook proteins ahead

Brown ground turkey or dice chicken the night before and store it in the fridge. This cuts down active time when you are ready to layer everything.

Swap in whole grains

Use quinoa or brown rice instead of regular pasta for the base. These add more protein and fiber while still soaking up sauces well.

Layer vegetables generously

Chop extra broccoli, spinach, or zucchini into the mix. They add volume and nutrients so each serving feels more filling.

Cheesy Chicken Broccoli Quinoa Casserole

This casserole brings together tender chicken, crisp broccoli, and fluffy quinoa in a simple cheese sauce. It works well for weeknight meals when you want a filling dish that uses mostly pantry staples and comes together in one baking dish.

The result is savory and creamy with a slight crunch from the broccoli. Quinoa adds a nutty note that balances the richness of the cheese.

Ingredients

  • 1 cup quinoa, rinsed
  • 1 pound boneless skinless chicken breast, cut into 1-inch pieces
  • 3 cups broccoli florets
  • 1 1/2 cups shredded cheddar cheese
  • 1 cup milk
  • 1 small onion, diced
  • 2 garlic cloves, minced
  • 1 tablespoon olive oil
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper

Instructions

  1. Preheat the oven to 375°F and lightly grease a 9×13-inch baking dish.
  2. Cook the quinoa according to package directions in a medium saucepan, then set it aside.
  3. Heat the olive oil in a large skillet over medium heat. Add the onion and garlic and cook for 2 minutes until softened.
  4. Add the chicken pieces to the skillet along with the salt and pepper. Cook for 6 to 8 minutes until the chicken is no longer pink.
  5. Stir in the broccoli florets and cook for 3 minutes until they turn bright green.
  6. Remove the skillet from heat. Add the cooked quinoa, milk, and 1 cup of the cheddar cheese. Stir until evenly combined.

  8. Bake for 20 minutes until the cheese is melted and bubbly. Let it rest for 5 minutes before serving.

Extra Tips

Use freshly shredded cheese instead of pre-shredded for the smoothest sauce. Leftovers keep well in the fridge for up to three days and reheat nicely in the microwave with a splash of milk to loosen the texture.Course: Main Course Cuisine: American Equipment: Large skillet, Medium saucepan, 9×13 baking dish
