Pin A comforting, creamy casserole featuring tender chicken, fresh broccoli, and a golden cheddar cheese topping—perfect for a family dinner or potluck.
I first made this bake on a busy weeknight when I wanted something cozy and quick. The combination of chicken, broccoli, and cheddar greeted my family with a warm, homey aroma from the oven.
Ingredients
- Chicken breast: 2 cups cooked, diced or shredded
- Broccoli florets: 3 cups fresh
- Unsalted butter: 2 tablespoons
- All-purpose flour: 2 tablespoons
- Whole milk: 1 cup
- Low-sodium chicken broth: 1/2 cup
- Dijon mustard: 1 teaspoon
- Garlic powder: 1/2 teaspoon
- Onion powder: 1/2 teaspoon
- Salt: 1/2 teaspoon
- Black pepper: 1/4 teaspoon
- Sharp cheddar cheese, shredded: 1 1/2 cups (divided)
- Panko breadcrumbs: 1/2 cup
- Olive oil: 1 tablespoon
- Crushed red pepper flakes: 1/4 teaspoon (optional)
Instructions
- Prep the Oven & Dish:
- Preheat the oven to 375°F (190°C). Lightly grease a 9x13-inch (23x33 cm) baking dish.
- Prepare the Broccoli:
- Steam or blanch broccoli florets in boiling water for 2-3 minutes until just tender and bright green. Drain and set aside.
- Make the Sauce:
- In a medium saucepan, melt butter over medium heat. Stir in flour and cook for 1 minute, whisking constantly. Gradually add milk and chicken broth, whisking to prevent lumps. Cook for 3-4 minutes until sauce thickens. Stir in Dijon mustard, garlic powder, onion powder, salt, and black pepper. Remove from heat. Add 1 cup cheddar cheese to the sauce and stir until melted and smooth.
- Combine & Assemble:
- In a large bowl, combine cooked chicken, blanched broccoli, and cheese sauce. Mix well. Spread mixture evenly in prepared baking dish.
- Add Cheese & Topping:
- Sprinkle remaining 1/2 cup cheddar cheese over the top. In a small bowl, toss panko breadcrumbs with olive oil (and red pepper flakes, if using), then sprinkle over casserole.
- Bake & Serve:
- Bake for 25-30 minutes until bubbling and top is golden brown. Let cool for 5 minutes before serving.
