How to Make Baked Potato Chicken and Broccoli Casserole Recipe
Step 1: Preheat and Prepare Your Oven
Start by setting your oven to 375°F (190°C). Preheating ensures your casserole cooks evenly and the top crisps up beautifully.
Step 2: Cook the Potatoes
Boil the peeled and cubed russet potatoes in salted water for about 10 minutes until tender but still holding their shape. Drain and set them aside – these will provide the creamy base that makes this casserole so comforting.
Step 3: Blanch the Broccoli
Using the same pot, bring fresh water to a boil and blanch the broccoli florets for 3 minutes. This keeps them bright green, tender-crisp, and full of vibrant color, ready to add freshness and texture to your dish.
Step 4: Prepare the Creamy Sauce
In a large mixing bowl, combine sour cream, milk, one cup of shredded cheddar cheese, garlic powder, onion powder, salt, and pepper. Stir until everything is smooth and well blended. This luscious sauce will coat the chicken, potatoes, and broccoli, creating a luscious harmony of flavors.
Step 5: Combine Ingredients
Gently fold the cooked potatoes, diced chicken, and blanched broccoli into the creamy sauce, making sure every piece is nicely covered. Then transfer this mixture into a greased 9×13-inch baking dish, spreading it out evenly to prepare for baking.
Step 6: Add the Topping and Bake
Mix the breadcrumbs with melted butter in a small bowl to create that golden crust magic. Sprinkle the remaining cheddar cheese evenly over the casserole, followed by the breadcrumb mixture. Slide your dish into the oven and bake for 20-25 minutes or until the top is beautifully golden brown and bubbly.
Step 7: Let it Rest Before Serving
Once out of the oven, allow the casserole to rest for about 5 minutes. This brief pause makes it easier to serve and helps all the flavors settle perfectly.
How to Serve Baked Potato Chicken and Broccoli Casserole Recipe

Garnishes
A sprinkle of freshly chopped parsley or chives brightens up the plate with color and adds a subtle fresh note that pairs wonderfully with the richness of the casserole. For extra indulgence, a dollop of sour cream on top can elevate each bite.
Side Dishes
This casserole is a complete meal on its own but pairs wonderfully with simple sides like a crisp garden salad or roasted vegetables to add extra greens and variety to the plate. A crusty bread roll on the side is also great to mop up any creamy goodness left on your plate.
Creative Ways to Present
Consider serving this casserole in individual ramekins for a charming, personalized touch at dinners. You can also turn leftovers into stuffed bell peppers or bake them into a hearty breakfast hash – the savory flavors lend themselves to many tasty reinventions.
Make Ahead and Storage
Storing Leftovers
Place any leftover Baked Potato Chicken and Broccoli Casserole Recipe in an airtight container, and it will stay fresh in the refrigerator for up to 3 days. This makes it perfect for quick weeknight lunches or dinners when time is tight.
Freezing
You can freeze the casserole either before baking or after – just wrap it tightly with plastic wrap and foil to prevent freezer burn. When frozen properly, it will keep well for up to 2 months without losing flavor or texture.
Reheating
Reheat your casserole in the oven at 350°F (175°C) for about 20 minutes until it’s warmed through and bubbly again. Avoid the microwave for reheating if possible, as the crust may lose its crunch, and the dish might become a bit watery.
FAQs
Can I use frozen broccoli instead of fresh?
Yes, you can substitute frozen broccoli, but be sure to thaw and drain it thoroughly to avoid adding excess water that could make the casserole soggy.
Is there a good vegetarian substitute for the chicken?
Absolutely! You can use cooked mushrooms, tofu, or extra vegetables like cauliflower for a delightful vegetarian version of this casserole.
Can I use a different type of cheese?

How spicy is this recipe?
This Baked Potato Chicken and Broccoli Casserole Recipe is mild and comforting by nature, but you can add a pinch of cayenne or some chopped jalapeños to give it a gentle kick if you like.
Can I prepare this casserole ahead of time?
Yes! You can assemble the casserole the day before and keep it covered in the refrigerator. Simply add the breadcrumb topping right before baking to keep it crisp and fresh.
