Ingredients

  

For the Casserole

• 1.5 lbs boneless, skinless chicken breasts cut into 1-inch cubes
• 2.5 lbs Yukon Gold potatoes peeled and sliced 1/8-inch thick
• 1 medium yellow onion diced
• 3 cloves garlic minced
• 2 tbsp olive oil
• 2 cups shredded sharp cheddar cheese divided
• 2 tbsp fresh parsley chopped, for garnish
• 1 tsp salt for seasoning chicken
• 0.5 tsp black pepper for seasoning chicken

For the Creamy Cheese Sauce

• 4 tbsp unsalted butter
• 0.25 cup all-purpose flour
• 2 cups whole milk warmed
• 1 cup low-sodium chicken broth
• 1 tsp Dijon mustard
• 1 tsp paprika
• 1 tsp dried thyme
• 0.5 tsp salt
• 0.25 tsp black pepper

Equipment

• 9x13 inch Casserole Dish
• Large Skillet
• Medium Saucepan
• Large Mixing Bowl
• Whisk

Method

 

Prepare the Base

• Preheat your oven to 400°F (200°C). Grease a 9x13 inch casserole dish with butter or non-stick spray.
• Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Season the chicken cubes with 1 tsp salt and 0.5 tsp pepper. Add the chicken to the skillet and cook for 5-7 minutes, until browned and cooked through. Remove the chicken from the skillet and set aside.
• In the same skillet, add the remaining 1 tablespoon of olive oil. Add the diced onion and cook for 4-5 minutes, until softened. Add the minced garlic and cook for another minute until fragrant. Remove from skillet.

Make the Creamy Cheese Sauce

• In a medium saucepan, melt the 4 tablespoons of butter over medium heat. Whisk in the flour and cook for 1 minute, stirring constantly, to create a roux.
• Gradually whisk in the warm milk and chicken broth until the mixture is smooth. Bring to a simmer and cook for 3-5 minutes, stirring frequently, until the sauce has thickened.
• Remove the saucepan from the heat. Stir in the Dijon mustard, paprika, dried thyme, 0.5 tsp salt, and 0.25 tsp pepper. Add 1 cup of the shredded cheddar cheese and stir until the cheese is completely melted and the sauce is smooth.

Assemble and Bake

• In a large mixing bowl, combine the cooked chicken, sautéed onions and garlic, and the thinly sliced potatoes. Pour the cheese sauce over the mixture and gently toss everything together until well-coated.
• Transfer the mixture to the prepared casserole dish and spread it into an even layer. Top with the remaining 1 cup of shredded cheddar cheese.
• Cover the casserole dish tightly with aluminum foil. Bake for 35 minutes. Then, remove the foil and bake for an additional 20-25 minutes, or until the potatoes are tender and the top is golden brown and bubbly.
• Let the casserole rest for 10-15 minutes before serving. This allows it to set up. Garnish with fresh parsley before serving.

Notes

Potato Slicing Tip: For perfectly even potato slices, a mandoline slicer works best. If you don't have one, slice them as thinly and uniformly as you can with a sharp knife. Uniform thickness ensures they cook evenly.
Make-Ahead: You can assemble the casserole (without the final cheese topping) up to 24 hours in advance. Cover and refrigerate. When ready to bake, add 10-15 minutes to the initial covered baking time.
Storage: Store leftovers in an airtight container in the refrigerator for up to 4 days.

Pro Tips for Making This Chicken Potato Casserole

Over the years, I’ve learned a few things that take this dish from good to great. Here are some of my favorite tips:

• Don’t Overcook the Potatoes: Boil the potatoes just until they are tender-crisp (a fork can pierce them but with some resistance). They will finish cooking in the oven, and this step prevents them from turning to mush.
• Shred Your Own Cheese: This is a big one! Pre-shredded cheeses are often coated in starches that can make your sauce grainy. Shredding a block of sharp cheddar yourself will give you the smoothest, meltiest sauce.
• Taste the Sauce: Before you assemble the casserole, taste the cheese sauce! It might need an extra pinch of salt or pepper. A well-seasoned sauce is the key to a flavorful Chicken Potato Casserole.
• My Secret Trick: A tiny bit of Dijon mustard in the cheese sauce is my secret weapon. You won’t taste the mustard, but it magically brightens and deepens the cheddar flavor.

Fun Variations / Easy Substitutions for Chicken Potato Casserole

One of the things I love most about cooking is making a recipe my own! Here are a few fun ways to switch up this casserole:

• Add a Veggie Boost: This recipe is fantastic with added vegetables. Stir in a cup of steamed broccoli florets or sautéed mushrooms for extra flavor and nutrients. It reminds me of my Cauliflower and Broccoli Casserole.
• Bring Some Heat: If your family likes a little spice, add a pinch of cayenne pepper or a dash of hot sauce to the cheese sauce. Diced jalapeños would also be a delicious addition.
• Switch Up the Cheese: While sharp cheddar is classic, don’t be afraid to experiment! A mix of Gruyère and white cheddar adds a wonderful nutty flavor, or you could try Monterey Jack for an extra creamy melt.
• Crispy Topping: For a crunchy top, mix a half-cup of Panko breadcrumbs with two tablespoons of melted butter and sprinkle over the casserole before baking.

What to Serve With Chicken Potato Casserole

Because this Chicken Potato Casserole is so rich and hearty, I love to pair it with something light and fresh. Here are a few of my go-to sides:

• A simple green salad with a bright lemon vinaigrette.
• Steamed green beans or roasted asparagus.
• Garlic bread for scooping up every last bit of that creamy sauce.

My main philosophy is to keep the sides simple. The casserole is the star of the show, so a simple, crisp vegetable is all you need to round out the meal.

How to Store Chicken Potato Casserole

This is one of my favorite dishes for leftovers! Here’s how to store it properly:

• In the Fridge: Allow the casserole to cool completely, then cover it tightly or transfer it to an airtight container. It will keep in the refrigerator for up to 4 days.
• Reheating: To reheat, you can microwave individual portions or place the entire casserole (covered with foil) in a 350°F (175°C) oven until warmed through. My little tip is to add a splash of milk before reheating to help make the sauce creamy again.

Nutritional Benefits

This hearty Chicken Potato Casserole is a wonderful source of protein and carbohydrates, making it a balanced and satisfying meal for the whole family. It provides lasting energy and is the kind of comforting food that nourishes both body and soul.

FAQs

Can I use a different type of potato?

Yes, Russets work, but they can be a bit grainier. Red potatoes are another great option as they hold their shape well. Yukon Golds are my favorite for this Chicken Potato Casserole because they become so wonderfully creamy.

Can I make this ahead of time?

Absolutely! You can assemble the entire casserole, cover it tightly, and refrigerate for up to 24 hours before baking. Just remember to add 10-15 minutes to the baking time since it will be going into the oven cold.

Can I use leftover chicken?

Yes, this is a perfect recipe for leftover cooked chicken! Just shred or dice about 3 cups of cooked chicken and skip the step of cooking it from raw. It makes this Chicken Potato Casserole come together even faster.

Is this recipe freezer-friendly?

Yes! Bake and cool the casserole completely. Cover it tightly with both plastic wrap and foil, then freeze for up to 3 months. For best results, thaw it overnight in the refrigerator before reheating in the oven.
