  • Fresh broccoli florets: 3 cups
  • 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: 1 1/2 cups, shredded (divided)

Instructions

Prep Oven and Baking Dish:
Preheat the oven to 375°F (190°C). Lightly grease a 9x13-inch (23x33 cm) baking dish.
Prepare Broccoli:
Steam or blanch the broccoli florets in boiling water for 2-3 minutes until just tender and bright green. Drain and set aside.
Make Cheese Sauce:
In a medium saucepan, melt the butter over medium heat. Stir in the flour and cook for 1 minute, whisking constantly. Gradually add the milk and chicken broth, whisking to prevent lumps. Cook for 3-4 minutes until the sauce thickens. Stir in Dijon mustard, garlic powder, onion powder, salt, and black pepper. Remove from heat. Add 1 cup of cheddar cheese to the sauce and stir until melted and smooth.
Combine Ingredients:
In a large bowl, combine the cooked chicken, blanched broccoli, and cheese sauce. Mix well. Spread the mixture evenly in the prepared baking dish.
Add Toppings:
Sprinkle the 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 the casserole.
Bake:
Bake for 25-30 minutes until bubbling and the top is golden brown. Let cool for 5 minutes before serving.
