How to Make Cheesy Baked Potato Chicken and Broccoli Casserole
This Cheesy Baked Potato Chicken and Broccoli Casserole is a dream to make, combining simple ingredients into a flavor-packed masterpiece. With its creamy sauce, tender chicken, and hearty potatoes, it’s a dish that truly warms the soul. The preparation time is approximately 20 minutes, and the baking time is about 45-55 minutes, making it perfectly manageable for a weeknight.
Step-by-Step Instructions
- Preheat your oven and prepare the baking dish: Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish with cooking spray or butter. This will prevent the casserole from sticking.
- Cook the chicken: In a large skillet over medium-high heat, cook the bite-sized chicken pieces with a tablespoon of oil (if not using an oil-free method) until they are browned and cooked through. Season with salt, pepper, garlic powder, and onion powder as they cook. Once cooked, remove the chicken from the skillet and set aside.
- Blanch the broccoli (if using fresh): If you are using fresh broccoli, it’s a good idea to blanch it briefly to ensure it’s tender. Bring a pot of lightly salted water to a boil, add the broccoli florets, and cook for 2-3 minutes. Immediately drain and rinse with cold water to stop the cooking process. If using frozen broccoli, you can skip this step.
- Prepare the creamy sauce: In a medium bowl, whisk together the condensed cream of chicken soup, milk, and melted butter until smooth. Stir in ½ cup of the shredded cheddar cheese and ¼ cup of the grated Parmesan cheese. Season with additional salt and pepper to your liking.
- Assemble the casserole: Arrange the thinly sliced potatoes in a single layer on the bottom of the prepared baking dish. If some slices overlap slightly, that’s perfectly fine.
- Add the chicken and broccoli: Evenly distribute the cooked chicken pieces over the layer of potatoes. Then, scatter the blanched (or frozen) broccoli florets over the chicken.
- Pour the sauce: Pour the prepared creamy sauce evenly over the chicken, broccoli, and potatoes, ensuring all ingredients are well-coated.
- Top with cheese: Sprinkle the remaining ½ cup of shredded cheddar cheese and ¼ cup of grated Parmesan cheese over the top of the casserole.
- Bake the casserole: Cover the baking dish tightly with aluminum foil and bake for 30 minutes.
- Uncover and finish baking: Remove the aluminum foil and bake for an additional 15-25 minutes, or until the potatoes are tender when pierced with a fork and the cheese topping is golden brown and bubbly. The exact baking time will depend on the thickness of your potato slices and your oven.
- Rest and serve: Let the casserole rest for 5-10 minutes before serving. This allows the flavors to meld and the casserole to set slightly, making it easier to serve. Garnish with fresh parsley if desired.

Storing and Reheating Tips
- Refrigeration: Once the Cheesy Baked Potato Chicken and Broccoli Casserole has cooled completely, you can store any leftovers in an airtight container in the refrigerator for up to 3-4 days. Ensure the container is sealed tightly to maintain freshness and prevent contamination.
- Freezing: For longer storage, you can freeze portions of the casserole. Allow the casserole to cool completely before transferring it to freezer-safe containers or heavy-duty aluminum foil. It can be frozen for up to 2-3 months.
- Reheating from Refrigerator: To reheat, transfer a portion of the casserole to an oven-safe dish. Cover with foil and bake in a preheated oven at 350°F (175°C) for 20-30 minutes, or until heated through and bubbly. You can also reheat individual portions in the microwave, covered, until hot.
- Reheating from Freezer: To reheat from frozen, it’s best to thaw the casserole in the refrigerator overnight first. Once thawed, follow the reheating instructions for refrigerated leftovers. Alternatively, you can bake directly from frozen, but it will take significantly longer (approximately 45-60 minutes), covered, at 350°F (175°C), until heated through.
