- ½ cup milk – Milk helps create a smooth sauce that coats the potatoes evenly.
- 2 cups shredded cheddar cheese, divided – Cheddar cheese melts beautifully and creates a golden, bubbly topping. Save some for sprinkling over the casserole before baking.
- 1 small onion, diced – Onion adds sweetness and extra flavor as it cooks.
- 2 garlic cloves, minced – Fresh garlic gives the casserole a rich, savory taste.
- 1 teaspoon Italian seasoning – Italian seasoning adds a blend of herbs that complements the chicken and potatoes.
- 1 teaspoon paprika – Paprika adds mild smoky flavor and a touch of color.

How to Store and Reheat
Refrigerator
Store leftover Chicken Potato Casserole in an airtight container in the refrigerator for up to 4 days.
Freezer
Freeze the baked casserole in a freezer-safe container for up to 3 months. Thaw overnight in the refrigerator before reheating.
Reheating
Reheat individual portions in the microwave until hot, or bake the casserole in a 350°F (175°C) oven for about 20 minutes. If needed, stir in a splash of milk before reheating to restore the creamy texture.
Common Mistakes to Avoid
Cutting the potatoes too large
Dice the potatoes into evenly sized 1-inch pieces so they cook at the same rate. Larger pieces may still be firm when the casserole is finished.
Skipping the foil
Covering the casserole during the first part of baking traps steam, helping the potatoes become tender without drying out the top.
Using pre-shredded cheese only
Freshly shredded cheddar cheese melts more smoothly and creates a creamier casserole than pre-shredded cheese.
Overbaking the casserole
Bake only until the potatoes are fork-tender and the cheese is golden. Overbaking can dry out the chicken and sauce.
Forgetting to let it rest
Allow the casserole to sit for 10 minutes before serving. This helps the sauce thicken and makes it easier to scoop.
Frequently Asked Questions
Can I use rotisserie chicken?
Yes. Rotisserie chicken is a great shortcut and adds plenty of flavor while reducing prep time.
Do I need to cook the potatoes first?
No. As long as you cut the potatoes into evenly sized pieces and cover the casserole during baking, they’ll cook until tender in the oven.
Can I make Chicken Potato Casserole ahead of time?
Absolutely. Assemble the casserole, cover it tightly, and refrigerate it for up to 24 hours before baking.
Can I freeze Chicken Potato Casserole?
Yes. Bake the casserole first, let it cool completely, then freeze it for up to 3 months. Thaw overnight in the refrigerator before reheating.
What vegetables can I add?
Try broccoli, mushrooms, peas, spinach, corn, bell peppers, cauliflower, or green beans to make the casserole even more filling and nutritious.
Chicken Potato Casserole
Ingredients
Method
- Preheat the oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.
- Bring a large pot of salted water to a boil. Add the diced potatoes and cook for 8 to 10 minutes until just barely fork-tender. Drain well.
- Melt the butter in a large skillet over medium heat. Add the onion and cook for 4 to 5 minutes until softened.
- Stir in the garlic and cook for 30 seconds until fragrant.
- Sprinkle the flour over the onion mixture and cook for 1 minute, stirring constantly.
- Gradually whisk in the milk and chicken broth until smooth. Stir in the garlic powder, onion powder, thyme, salt, and black pepper, then simmer for 3 to 5 minutes until slightly thickened.
- Remove the skillet from the heat and stir in 1½ cups of the cheddar cheese and the Parmesan until melted and smooth.
- Gently fold the cooked chicken and potatoes into the cheese sauce until evenly coated.
- Transfer the mixture to the prepared baking dish and sprinkle with the remaining cheddar cheese.
- Bake for 25 to 30 minutes, or until the casserole is hot and bubbly. Broil for 2 to 3 minutes if desired for a golden cheese topping. Let the casserole rest for 10 minutes before garnishing with fresh parsley and serving.
Notes
- Parboil the potatoes before baking so they become tender without overcooking the cheese sauce. Skipping this step can leave the potatoes undercooked.
- Yukon Gold potatoes are the best choice because they hold their shape and have a naturally creamy texture. Russet potatoes will create a softer, fluffier casserole.
- Drain the potatoes well after boiling so excess moisture doesn’t thin the cheese sauce.
- Freshly shredded cheddar melts much more smoothly than pre-shredded cheese, resulting in a creamier casserole.
- The casserole can be assembled up to 24 hours in advance and refrigerated. Let it sit at room temperature for 20 to 30 minutes before baking, or add 10 to 15 minutes to the baking time if baking straight from the refrigerator.
