Ingredients for the Baked Potato Chicken and Broccoli Casserole

Each ingredient in this casserole plays a key role in building flavor and texture:

• Chicken Breast – Lean and protein-rich, diced chicken breast adds heartiness and substance to the dish.
• Russet Potatoes – Their starchy texture holds up well during baking and soaks up the cheesy sauce.
• Broccoli Florets – Adds a nutritious crunch and a pop of color, balancing out the richness.
• Cheddar Cheese – Melty and sharp, cheddar brings that classic casserole comfort.
• Mozzarella Cheese – For gooey stretchiness and a creamy complement to the cheddar.
• Heavy Cream – Adds richness to the sauce and binds the ingredients beautifully.
• Garlic Powder & Onion Powder – Boost the savory flavor without overpowering the dish.
• Olive Oil – Used for roasting the potatoes and chicken, adding depth and a crisp texture.
• Salt and Pepper – Essential for seasoning throughout the layers.

How To Make the Baked Potato Chicken and Broccoli Casserole

Step 1: Roast the Potatoes and Chicken

Preheat your oven to 400°F (200°C). Toss the diced potatoes and chicken with olive oil, salt, pepper, garlic powder, and onion powder. Spread evenly on a baking sheet and roast for 20-25 minutes until golden and cooked through.

Step 2: Steam the Broccoli

While the chicken and potatoes are roasting, lightly steam the broccoli florets until just tender. This helps keep their color and crunch.

Step 3: Make the Cheese Sauce

In a saucepan, warm the heavy cream over medium heat. Stir in the shredded cheddar and mozzarella cheeses until melted and smooth. Season with a pinch of salt and pepper.

Step 4: Combine Everything

In a large mixing bowl, combine the roasted chicken and potatoes, steamed broccoli, and cheese sauce. Gently fold everything together so it’s evenly coated.

Step 5: Bake the Casserole

Transfer the mixture into a greased baking dish. Sprinkle some extra cheddar and mozzarella on top. Bake at 375°F (190°C) for 15-20 minutes, or until the top is bubbly and golden brown.

Step 6: Cool and Serve

Let the casserole cool for about 5 minutes before serving. This helps the sauce thicken slightly and makes it easier to portion.

Frequently Asked Questions

1. Can I make this casserole ahead of time?
Yes! Assemble everything up to the baking step and refrigerate for up to 24 hours. When ready to bake, add 10 extra minutes to the cook time since it’s starting from cold.

2. Can I use rotisserie chicken instead of raw chicken breast?
Definitely. Shredded rotisserie chicken is a great time-saver and adds extra flavor. Just skip the roasting step for the chicken and mix it in when combining ingredients.

For a lighter take, substitute the heavy cream with milk or half-and-half, and use reduced-fat cheese. You can also cut back slightly on the cheese without losing too much richness.

Be sure to steam and drain the broccoli well and don’t skip roasting the potatoes and chicken. This helps eliminate excess moisture that can cause sogginess.

5. Can I add other vegetables to this casserole?
Absolutely! Cauliflower, spinach, bell peppers, or mushrooms would all be delicious additions. Just make sure to cook or drain them as needed to avoid excess liquid.
