- 1/4 cup milk: Lightens the creaminess just enough for silky texture.
- 2 tablespoons butter, melted: Infuses the potatoes with a rich, buttery flavor and helps them crisp up.
- 1/2 teaspoon garlic powder: Adds a subtle, warm garlic undertone.
- 1/2 teaspoon onion powder: Enhances savory notes without overpowering.

How to Make Baked Potato Chicken and Broccoli Casserole Recipe
Step 1: Prepare the Baking Dish and Potatoes
Start by preheating your oven to 375°F (190°C) and lightly greasing a 9×13-inch baking dish so nothing sticks and everything bakes evenly. In a large bowl, toss the diced russet potatoes with melted butter, garlic powder, onion powder, salt, and pepper. This seasoning mix ensures the potatoes develop amazing flavor and a touch of crispiness as they bake in the oven.
Step 2: Bake the Potatoes
Spread the seasoned potatoes in a single, even layer in your prepared dish. Bake them for 25 to 30 minutes until they become tender and just start to turn a beautiful golden color. This step forms a perfect base that’s soft inside and slightly crisp on top, setting the stage for the rest of the casserole’s flavors.
Step 3: Prepare the Broccoli and Chicken Mixture
While the potatoes bake, steam or blanch your broccoli until it’s just tender but still bright and firm—this helps retain that fresh bite. In a separate bowl, combine the cooked chicken, broccoli, sour cream, milk, and shredded cheddar cheese. This creamy mixture is the heart of the casserole, balancing the textures and tastes beautifully.
Step 4: Assemble and Bake the Casserole
Once your potatoes are perfectly baked, remove the dish from the oven and evenly spread the chicken and broccoli mixture over them. If you love cheesy dishes, sprinkle a little extra cheddar on top—it creates a marvelous golden, bubbly crust that’s hard to resist. Return the casserole to the oven and bake for an additional 15 to 20 minutes until everything is hot, melty, and inviting.
How to Serve Baked Potato Chicken and Broccoli Casserole Recipe

Garnishes
Simple garnishes can elevate the cozy appeal of this casserole. A sprinkle of fresh chopped green onions brightens the dish with a mild zest, while a dash of paprika or freshly cracked black pepper adds a subtle pop of color and flavor. For extra flair, a few crispy bacon bits or toasted breadcrumbs can provide a pleasant crunch.
Side Dishes
Though this casserole is a fulfilling meal on its own, pairing it with a light side salad or roasted vegetables can create a well-rounded dinner. Fresh greens with a lemon vinaigrette cut through the richness wonderfully, while warm crusty bread offers a satisfying texture contrast and helps scoop up any leftover sauce.
Creative Ways to Present
For a fun twist when serving, try dishing up the casserole in individual ramekins or small cast-iron skillets for a personal touch. Alternatively, add a handful of colorful bell pepper slices into the chicken and broccoli mixture before baking for a splash of vibrant color and sweet crunch. This casserole also reheats beautifully, so leftovers can transform into quick lunch bowls with a side of fresh fruit or greens.
Make Ahead and Storage
Storing Leftovers
This Baked Potato Chicken and Broccoli Casserole Recipe stays fantastic in the fridge for up to three days. Be sure to cover it tightly with foil or plastic wrap to keep it fresh. Refrigerated leftovers often taste even better as the flavors have more time to meld together.
Freezing
You can freeze this casserole either before or after baking. To freeze before baking, assemble the casserole in a freezer-safe dish, cover it well, and freeze for up to two months. When ready, bake it straight from frozen, adding additional baking time. If freezing after baking, cool completely, wrap tightly, and store for up to one month—then reheat gently to preserve texture.
Reheating
Reheat leftover casserole in the oven at 350°F (175°C) until warmed through, typically about 20 minutes. This method helps keep the potatoes and chicken tender while restoring that creamy, melty cheese goodness. If in a hurry, microwaving works too—just cover loosely and heat in short intervals to avoid drying out.
FAQs
Can I use other types of cheese in this casserole?
Absolutely! While cheddar cheese is traditional and melts perfectly, feel free to experiment with mozzarella, Monterey Jack, or even a sharp Parmesan for a different flavor profile that suits your taste.
Is this recipe suitable for meal prep?
Yes, it’s a fantastic meal prep option because it keeps well in the fridge and freezer. You can make it on the weekend, portion it out, and enjoy quick, homemade comfort food all week long.
Can I substitute the chicken for another protein?
Definitely—try cooked turkey, ham, or even tofu for a vegetarian-friendly alternative. Just adjust the seasoning slightly if needed to complement your chosen protein.
How do I make this casserole dairy-free?
To keep it dairy-free, swap cheese and sour cream for plant-based alternatives like vegan cheese shreds and coconut or cashew-based sour cream. The flavor and creaminess will be a bit different but still delicious.
What can I add for extra crunch on top?
For added texture, sprinkle crushed crackers, panko breadcrumbs, or crispy bacon bits on top before the final bake. This adds a delightful contrast to the creamy, tender layers below.
