About the Ingredients
Chicken Breasts or Thighs
Boneless and skinless, cut into bite-sized cubes. Thighs stay extra juicy, but breasts work beautifully, too.
Broccoli Florets
Fresh or frozen; both work. They add texture, nutrients, and color.
Olive Oil
Helps brown the chicken and lock in flavor.
Garlic Powder, Onion Powder, and Paprika
Build a savory seasoning base.
Salt and Black Pepper
Essential for balance and flavor.
Butter and Flour
The foundation of the roux, thickening the sauce for that creamy texture.
Milk and Chicken Broth
Combine for a smooth, flavorful liquid base.
Cheddar Cheese
Sharp cheddar gives that classic cheesy flavor.
Parmesan Cheese
Adds depth, saltiness, and richness.
Dry Mustard and Nutmeg (Optional)
Small additions that enhance the sauce’s flavor complexity.
Mozzarella Cheese
Melts beautifully, giving the casserole that irresistible stretch.
Panko Breadcrumbs
Provide a golden, crispy topping.
Melted Butter
Helps toast the breadcrumbs for a perfect crunch.
Tips & Tricks
Cut Chicken Evenly
This ensures all pieces cook at the same rate.
Use Fresh-Grated Cheese
Pre-shredded cheese contains anti-caking agents that prevent smooth melting.
Adjust the Sauce Consistency
If too thick, add a splash of milk; if too thin, simmer a bit longer.
Pro Tips
- Prep ahead: Assemble up to a day in advance, cover, and refrigerate until ready to bake.
- Add rice or pasta: For a heartier casserole, mix in cooked rice or noodles before baking.
- Enhance flavors: Add a pinch of cayenne for a subtle kick.
Step-by-Step Instructions
Prepare the Oven and Baking Dish
Preheat the oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.
Sear the Chicken and Broccoli
Heat olive oil in a large skillet. Season chicken with garlic powder, onion powder, paprika, salt, and pepper. Sear for 5–6 minutes until lightly golden. Add broccoli during the last 2 minutes to soften. Transfer both to the baking dish.
Create the Roux
In the same skillet, melt butter over medium heat. Stir in flour and cook for 1–2 minutes until lightly golden to make a roux.
Make the Cheese Sauce
Slowly whisk in milk and chicken broth until smooth. Cook 3–5 minutes until the sauce thickens.
Finish the Sauce
Lower heat and stir in 1½ cups cheddar cheese, Parmesan, and optional mustard and nutmeg until melted and creamy.
Combine and Bake
Pour the sauce evenly over the chicken and broccoli, stirring gently to coat. Top with remaining cheddar and mozzarella. Mix Panko with melted butter and sprinkle on top.
Bake the Casserole
Bake uncovered for 20–25 minutes until bubbly and golden brown.
Let It Rest
Let rest for 5–10 minutes before serving for easier slicing.
Delicious Variations
Spicy Kick
Add a pinch of red pepper flakes to the cheese sauce for a spicy twist.
Vegetarian Option
Replace chicken with chickpeas or tofu for a meatless version.
Mediterranean Flair
Incorporate sun-dried tomatoes and olives for a Mediterranean touch.
