Step-by-Step Instructions
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
Step 2: Cook the Broccoli
Bring a pot of water to a boil and blanch the broccoli florets for 2 minutes. Drain and immediately rinse with cold water to keep them bright green.
Step 3: Prepare the Chicken
If using freshly cooked chicken, dice or shred it into bite-sized pieces.
Step 4: Sauté the Aromatics
Melt the butter in a large skillet over medium heat. Add the onion and cook for 3–4 minutes until softened. Stir in the garlic and cook for another 30 seconds.
Step 5: Make the Roux
Sprinkle the flour over the onions and garlic. Stir continuously for 1 minute.
Step 6: Add the Liquids
Slowly whisk in the milk and chicken broth until smooth.
Step 7: Season
Add garlic powder, onion powder, paprika, salt, and black pepper. Simmer for 4–5 minutes until slightly thickened.
Step 8: Melt the Cheese
Reduce the heat to low and stir in 1½ cups cheddar, the mozzarella, and Parmesan cheese until completely melted and smooth.
Step 9: Combine
In a large bowl, combine the chicken, broccoli, cooked macaroni (if using), and cheese sauce. Mix until evenly coated.
Step 10: Fill the Baking Dish
Transfer the mixture to the prepared casserole dish and spread it evenly.
Step 11: Add the Topping
Sprinkle the remaining cheddar cheese evenly over the top.
Step 12: Bake
Bake uncovered for 25–30 minutes, or until the casserole is hot and bubbly.
Step 13: Broil (Optional)
Broil for 2–3 minutes for a golden, lightly browned cheese topping.
Step 14: Rest
Allow the casserole to rest for 5–10 minutes before serving.
Step 15: Garnish and Serve
Sprinkle with chopped parsley and freshly cracked black pepper. Serve warm.
