This Creamy Chicken Quinoa and Broccoli Casserole is a comforting and nutritious dish made with tender chicken, fluffy quinoa, crisp-tender broccoli, and a light, creamy cheese sauce. Everything bakes together in one dish for a satisfying and easy meal!


Ingredients

  • 1 cup uncooked quinoa (rinsed)

  • 2 cups low-sodium chicken broth or water

  • 2 cups cooked chicken, shredded or diced

  • 2 cups broccoli florets (fresh or frozen, lightly steamed)

  • 1 small onion, finely chopped

  • 2 cloves garlic, minced

  • 1 tbsp olive oil or butter

  • 1/2 cup plain Greek yogurt or sour cream

  • 1/2 cup milk (any kind)

  • 1 1/2 cups shredded cheddar cheese, divided

  • 1/2 tsp salt

  • 1/4 tsp black pepper

  • 1/2 tsp garlic powder

  • 1/4 tsp paprika

  • 2 tbsp grated Parmesan cheese (optional, for topping)

  • Optional: chopped parsley for garnish


Instructions

Cook the Quinoa

  1. In a saucepan, combine quinoa and chicken broth.

  2. Bring to a boil, then reduce to low, cover, and simmer for 15 minutes, or until quinoa is fluffy and liquid is absorbed. Set aside.

2. Prep the Casserole Base

  1. Preheat oven to 375°F (190°C).

  2. In a skillet, heat olive oil or butter over medium heat. Sauté onion and garlic until soft and fragrant (about 3–4 minutes).

3. Mix Everything Together

  1. In a large bowl, combine:

    • Cooked quinoa

    • Chicken, steamed broccoli, sautéed onion and garlic

    • Greek yogurt, milk, 1 cup cheddar cheese, and seasonings (salt, pepper, garlic powder, paprika)

  2. Mix until well combined.

4. Bake

  1. Pour the mixture into a greased 9×13-inch casserole dish.

  2. Top with remaining ½ cup cheddar cheese and Parmesan, if using.

  3. Bake for 20–25 minutes, or until bubbly and cheese is melted and golden.

5. Serve

  • Let rest for 5 minutes, then garnish with fresh parsley if desired. Serve warm!


Notes

  • Use rotisserie chicken for a shortcut!

  • Sub in cauliflower rice for quinoa if you want a low-carb version.

  • Add extras like mushrooms, peas, or shredded carrots for more veggies.

  • Store leftovers in an airtight container in the fridge for up to 4 days.
