Additional Cheese Topping

  • 1/2 cup shredded cheddar cheese

Vegetables (optional)

  • Optional: 1/2 cup broccoli florets or spinach

Seasoning

  • 1/2 tsp garlic powder

Instructions

Preheat the Oven

  • Preheat oven to 375°F (190°C).

Prepare the Chicken

  • Rinse chicken under cold water, pat dry, and season with salt, pepper, and garlic powder.

Make the Cheese Sauce

  • Melt butter in a saucepan over medium heat. Add flour and cook for 1 minute, stirring constantly to form a roux.
  • Slowly whisk in milk and simmer for 3-5 minutes until thickened. Remove from heat and stir in 1 cup of shredded cheddar cheese. Season with salt and pepper.

Assemble the Casserole

  • Place cooked chicken pieces in a large baking dish. Pour the cheese sauce evenly over the chicken. Add any additional vegetables if desired.
  • Sprinkle the remaining 1/2 cup of cheddar cheese on top.

Bake

  • Bake for 30-35 minutes or until the chicken is heated through, and the cheese is melted and bubbly.

Serve

  • Let the casserole rest for 5 minutes before serving.

Notes

  • Make-Ahead Tip: Assemble the casserole, cover it, and refrigerate until baking. Perfect for meal prep!
  • Variations: Try mixing in different cheeses like mozzarella, Parmesan, or Gruyère for a unique flavor. You can also use rotisserie chicken for convenience.
  • Customizations: Add your favorite vegetables like bell peppers, mushrooms, or broccoli for added flavor and nutrition.

Expert Tips

  • For Extra Creaminess: Use a high-quality sharp cheddar cheese and whisk in the milk slowly to prevent lumps.
  • To Keep Moisture: Cover with foil for the first half of baking, then uncover for a golden-brown crust.
