Ingredients:
- 3 cups Cooked Chicken Breast, shredded or diced
- 3 cups Fresh or Frozen Broccoli Florets
- 2 cups Milk (Whole or 2%)
- 1 cup Chicken Broth (Low Sodium)
- 4 tablespoons Unsalted Butter
- 4 tablespoons All-Purpose Flour
- 1 teaspoon Salt
- ½ teaspoon Black Pepper (freshly ground)
- ½ teaspoon Garlic Powder
- ¼ teaspoon Mustard Powder
- 1 ½ cups Sharp Cheddar Cheese, shredded
- ½ cup Gruyère or Monterey Jack Cheese, shredded
- ½ cup Shredded or grated carrot
- ½ cup Panko Breadcrumbs
- ¼ cup Grated Parmesan Cheese
- 1 tablespoon Melted Butter (for topping)
Instructions:
- Preheat oven to 375°F (190°C). Lightly grease a 9x13 inch casserole or baking dish.
- Briefly boil or steam the broccoli florets until they are tender-crisp (about 3 minutes). Drain thoroughly and set aside.
- In a large saucepan over medium heat, melt the 4 tbsp of butter. Whisk in the flour constantly for 1-2 minutes until a smooth paste (the roux) forms.
- Slowly whisk in the cold milk, followed by the chicken broth, ensuring no lumps form. Bring the mixture to a gentle simmer, whisking often, until the sauce thickens enough to coat the back of a spoon (about 5-7 minutes).
- Remove the sauce from the heat. Whisk in the salt, pepper, garlic powder, and mustard powder. Stir in 1 cup of the shredded Cheddar and all of the Gruyère/Jack until melted and smooth.
- In a large bowl, gently toss the cooked chicken, blanched broccoli, grated carrot, and the remaining ½ cup of Cheddar cheese. Pour the cheese sauce over the mixture and stir carefully until everything is evenly coated.
- Transfer the mixture into the prepared casserole dish, spreading it evenly.
- In a small bowl, mix the Panko breadcrumbs, Parmesan cheese, and 1 tbsp of melted butter until crumbly. Sprinkle evenly over the casserole filling.
- Bake for 25–30 minutes, or until the filling is bubbling hot throughout and the topping is golden brown and crisp. Let rest for 5 minutes before serving.
