Ingredients

• 2 pounds boneless skinless chicken thighs or chicken breast, cut into bite size pieces
• 1 cup plain Greek yogurt
• 1 cup low fat cottage cheese
• 1 cup shredded mozzarella or cheddar cheese
• 1 cup cooked quinoa or brown rice
• 1 cup broccoli florets, chopped small
• 1 cup bell peppers, diced
• 1 small onion, finely chopped
• 2 cloves garlic, minced
• 1 teaspoon salt
• 1 teaspoon black pepper
• 1 teaspoon paprika
• 1 teaspoon dried Italian seasoning
• 1 tablespoon olive oil

Step By Step Instructions

1. Preheat your oven to 375 degrees F and lightly grease a baking dish with olive oil.
2. Heat olive oil in a pan over medium heat. Add the chicken pieces and cook until lightly browned on the outside. They do not need to be fully cooked.
3. Add onion and garlic to the pan. Cook for 2 to 3 minutes until soft and fragrant.
4. In a large bowl, mix Greek yogurt, cottage cheese, half of the shredded cheese, salt, pepper, paprika, and Italian seasoning until smooth.
5. Add the cooked chicken, quinoa, broccoli, and bell peppers to the bowl. Stir until everything is evenly coated.
6. Transfer the mixture into the prepared baking dish and spread it out evenly.
7. Sprinkle the remaining shredded cheese over the top.
8. Bake uncovered for 30 to 35 minutes until the casserole is bubbling and the top is lightly golden.
9. Let the casserole rest for 5 minutes before serving so it sets nicely.

Common Mistakes To Avoid

Do not overcook the chicken before baking. It will finish cooking in the oven and stay juicy. Avoid using too much liquid, as this can make the casserole watery. Chop vegetables into small, even pieces so they cook evenly. Skipping the rest time can cause the casserole to fall apart when served.

Tips For Success

For extra protein, use boneless skinless chicken thigh recipes instead of breast. Thighs stay tender and add more flavor. You can swap quinoa for cauliflower rice if you want a lower carb option. If you enjoy easy chicken breast recipes, breast works well here too. Season well, as balanced seasoning brings out the creamy texture and baked flavor.

How To Serve

Serve this casserole hot with a simple green salad or steamed vegetables. It pairs nicely with roasted carrots or green beans. If you enjoy healthy dinner recipes, this dish fits well into weekly meal plans. For variety, you can also pair it with a light chicken dish like this Santa Fe chicken recipe on another night.

Flavor Add In Ideas

Add chopped spinach for extra greens or mushrooms for a deeper savory taste. A pinch of chili flakes adds gentle heat. For a sweeter balance, roasted corn works well. If you like bold flavors, try pairing this casserole week with a honey garlic chicken dish to keep dinners exciting.
