Why You’ll Love This Baked Potato Chicken and Broccoli Casserole

This recipe checks all the boxes: it’s filling, family-friendly, freezer-friendly, and a breeze to put together.

What Kind of Potatoes Work Best for This Casserole?

Russet potatoes hold their shape nicely after baking and soak up the creamy sauce well, making them a solid choice. Yukon golds also work if you prefer a slightly buttery texture. Avoid red potatoes, which can become too soft and waxy for this kind of bake.

Ingredients for the Baked Potato Chicken and Broccoli Casserole

The ingredients in this casserole are simple and easy to find, but each one plays an essential role in making the dish creamy, cheesy, and satisfying.

Chicken breast: This lean protein becomes tender and flavorful baked into the creamy sauce.
Russet potatoes: They hold up well during baking and absorb all the delicious flavors.
Broccoli florets: Adds a burst of green color and freshness to balance the richness.
Cheddar cheese: Melts into the sauce and gives that golden crust on top.
Cream cheese: Brings tanginess and richness to the sauce.
Milk: Helps loosen the sauce to the perfect pourable consistency.
Garlic powder: Adds subtle savory depth without overpowering the dish.
Salt and black pepper: Essential for seasoning and enhancing every layer of flavor.
Olive oil: Helps roast the potatoes and chicken evenly.

How To Make the Baked Potato Chicken and Broccoli Casserole

Step 1: Prep the Ingredients

Preheat your oven to 400°F. Peel and dice the russet potatoes into bite-sized cubes. Cut the chicken into chunks and lightly season with salt and pepper. Steam or blanch the broccoli just until it turns bright green.

Step 2: Roast the Potatoes and Chicken

Toss the diced potatoes and chicken pieces in olive oil, salt, and garlic powder. Spread them on a large baking sheet and roast for 20 minutes until the chicken is cooked through and the potatoes are fork-tender.

Step 3: Make the Cheese Sauce

In a saucepan, melt the cream cheese with milk over medium heat, whisking until smooth. Stir in shredded cheddar cheese and continue to whisk until the sauce is thick and creamy. Season with salt and pepper to taste.

Step 4: Assemble the Casserole

In a greased baking dish, layer the roasted potatoes and chicken with the broccoli florets. Pour the cheese sauce over the top, using a spatula to spread it evenly. Sprinkle extra cheese on top if desired.

Step 5: Bake Until Golden

Place the dish in the oven and bake uncovered for 15–20 minutes, or until the cheese is bubbly and golden brown.
