Homemade Chicken and Broccoli Casserole

This Homemade Chicken and Broccoli Casserole is a creamy, cheesy, comforting family dinner made with tender chicken, fresh broccoli, a savory homemade sauce, and a golden cheese topping. It’s simple, satisfying, and perfect for busy weeknights or make-ahead meals.

Can Chicken and Broccoli Casserole Support Weight Loss Goals?

Yes. Chicken and broccoli make an excellent combination for a balanced meal because chicken provides lean protein while broccoli adds fiber and volume. For a lighter casserole, use Greek yogurt in the sauce, reduced-fat cheese, and a smaller amount of butter.

Does It Fit a High-Protein Lifestyle?

Yes. Chicken breast makes this casserole naturally protein-rich. Using Greek yogurt or blended cottage cheese in the sauce can increase the protein content even further.

My Personal Experience

• Blanching the broccoli briefly keeps it vibrant and tender-crisp.
  It prevents the broccoli from becoming mushy during the longer baking time.
• A homemade sauce tastes much better than canned soup.
  Garlic, onion, chicken broth, and a little Dijon give it much more depth.
• Using two cheeses gives the best topping.
  Cheddar provides flavor while mozzarella creates that irresistible stretch.
• Letting the casserole rest before serving matters.
  The sauce thickens and the portions hold together much better.

Directions

1. Preheat the oven — 5 minutes
   Preheat oven to 190°C/375°F. Lightly grease a 9×13-inch baking dish.
2. Blanch the broccoli — 4 minutes
   Bring a large pot of salted water to a boil. Add broccoli and cook for approximately 2 minutes. Drain immediately and rinse briefly under cold water. Drain very well and pat dry. Texture cue: Broccoli should be bright green and still slightly firm.
3. Cook the chicken — 7–8 minutes
   Heat olive oil in a large skillet over medium-high heat. Add chicken, onion, paprika, Italian seasoning, salt, and pepper. Cook for approximately 6–8 minutes, stirring occasionally. Add garlic during the final minute. The chicken should be mostly cooked but doesn’t need to be completely finished yet.
4. Make the sauce — 7 minutes
   Melt butter in a saucepan over medium heat. Whisk in flour and cook for approximately 1 minute. Slowly whisk in chicken broth and milk. Cook for 3–4 minutes, stirring constantly, until thickened. Remove from heat. Whisk in Greek yogurt, Dijon mustard, garlic powder, black pepper, and Parmesan. Texture cue: The sauce should be creamy and coat the back of a spoon.
5. Combine — 3 minutes
   Add chicken and broccoli to the prepared baking dish. Pour the homemade sauce evenly over everything. Gently mix.
6. Add cheese — 2 minutes
   Sprinkle cheddar, mozzarella, and Parmesan over the top.
7. Bake — 20 minutes
   Bake uncovered at 190°C/375°F for approximately 20 minutes. Visual cue: The casserole should be bubbling around the edges with a melted golden cheese topping.
8. Optional browning — 2 minutes
   For a deeper golden top, broil for 1–2 minutes, watching carefully.
9. Rest — 10 minutes
   Remove from the oven and let stand for approximately 10 minutes before serving.
10. Garnish and serve
    Sprinkle with fresh parsley or green onions.
