Ingredients

Main Ingredients
- 2 cups cooked chicken breast, cubed
- 4 medium potatoes, peeled and diced
- 2 cups broccoli florets
- 1 cup shredded cheddar cheese
- 1 cup shredded mozzarella cheese
- 1/2 cup grated Parmesan cheese
For the Creamy Sauce
- 2 tablespoons butter
- 3 tablespoons all-purpose flour
- 2 cups milk
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1/2 teaspoon paprika
- Salt and black pepper to taste
Step-by-Step Instructions
Step 1: Prepare the Vegetables
Preheat your oven to 375°F (190°C). Peel and dice the potatoes into 1-inch cubes. Cut the broccoli into small florets. Steam or boil the potatoes and broccoli for 5-7 minutes until slightly tender but still firm. Drain thoroughly.
Step 2: Make the Cheese Sauce
In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1 minute until golden. Gradually whisk in the milk until smooth. Cook for 3-4 minutes until thickened. Remove from heat and stir in the garlic powder, onion powder, paprika, salt, and pepper. Add 3/4 of the mixed cheeses (reserve some for topping).
Step 3: Assemble the Casserole
In a 9×13 inch baking dish, combine the cooked chicken, potatoes, and broccoli. Pour the cheese sauce over everything and mix gently to coat. Top with the remaining cheese mixture.
Step 4: Bake to Perfection
Cover with foil and bake for 20 minutes. Remove foil and bake for another 10-15 minutes until the cheese is bubbly and golden brown. Let stand for 5 minutes before serving.
Expert Tips
Perfect Cheese Sauce: For an extra creamy sauce, use whole milk and don’t rush the thickening process. The sauce should coat the back of a spoon before adding the cheese.
Vegetable Variations: Feel free to add carrots, peas, or corn to make this a complete vegetable chicken bake. Just adjust cooking times accordingly.
Make-Ahead Option: Assemble the casserole completely, cover, and refrigerate overnight. Add 10-15 minutes to the baking time when cooking from cold.

How do I store leftovers?
Store cooled leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave until heated through.
Can I make this recipe gluten-free?
Yes! Simply use gluten-free flour blend for the sauce and ensure all other ingredients are gluten-free certified.
What’s the best way to cook the chicken?
You can use rotisserie chicken for convenience, or bake chicken breasts seasoned with salt and pepper at 375°F for 25-30 minutes until cooked through.
