Ingredients You’ll Need

What makes this Loaded Chicken Casserole truly shine is its perfect balance of simple, flavorful ingredients. Each one brings something special to the table—texture, creaminess, sharpness, or a pop of color—that makes every bite absolutely irresistible.

Cooked chicken breast: Shredded or diced rotisserie chicken works beautifully here, infusing the casserole with hearty protein and tender, savory bites.
Diced potatoes (russet or Yukon gold): These form the foundation of the dish, turning delightfully golden and crisp under gentle roasting.
Shredded cheddar cheese: The classic melt and sharp flavor ties the casserole together, making it extra cheesy and comforting.
Cooked and crumbled bacon: Smoky and salty, bacon adds an irresistible savory crunch to every layer.
Sour cream: This gives the filling a velvety tang and keeps everything luxuriously moist.
Mayonnaise: Blends with the sour cream to create the irresistibly creamy sauce that holds the casserole together.
Chopped green onions: Fresh, vibrant, and a little peppery, these are perfect for both the middle and top of your casserole.
Garlic powder: Adds subtle depth and makes every forkful burst with flavor.
Onion powder: Complements both the potatoes and cheese, balancing out the creaminess.
Salt and black pepper: Essential for pulling all the flavors together—be sure to taste and adjust as you go.
Olive oil: Ensures the potatoes roast beautifully and don’t stick to the pan.

How to Make Loaded Chicken Casserole

Step 1: Prep and Roast the Potatoes

Start by getting your oven nice and hot at 400°F. While it preheats, toss your diced potatoes with olive oil, salt, pepper, garlic powder, and onion powder. This not only gives the potatoes flavor from the get-go but also gets them ready to roast up golden and crispy. Spread them out evenly in a greased 9×13-inch baking dish—which gives plenty of room for all the layers to shine—and pop the dish in the oven for about 25–30 minutes, just until the potatoes are tender but not too soft.

Step 2: Mix the Creamy Chicken Layer

While your potatoes are roasting away, grab a large bowl and combine the cooked chicken with the sour cream, mayonnaise, half of your shredded cheddar cheese, and half of the chopped green onions. This mixture becomes luxuriously creamy and perfectly seasoned, making every bite rich but surprisingly bright from the green onions.

Step 3: Layer and Assemble

When your potatoes are ready, pull them from the oven and don’t forget to lower the heat to 375°F. Spread the chicken mixture evenly over your roasted potatoes—be gentle so you don’t mash the potatoes. Top everything with the remaining cheddar cheese and the irresistible crumbled bacon, ensuring every corner promises cheesy, smoky goodness.

Step 4: Bake Until Hot and Bubbling

Slide your casserole back into the oven and bake for another 15–20 minutes. This final bake lets the cheese melt into gooey perfection and the whole casserole bubble invitingly. Once it’s golden and hot, sprinkle on those reserved green onions for a burst of color and freshness right before serving.

How to Serve Loaded Chicken Casserole

Garnishes

For your Loaded Chicken Casserole, a final handful of fresh green onions right before serving gives a vibrant crunch and a pop of color. If you’re feeling extra fancy, try a sprinkle of fresh parsley, or for spice lovers, a scattering of sliced jalapeños for some heat. A spoonful of extra sour cream on the side never hurts, either!

Side Dishes

This casserole truly stands on its own, but if you want to round out your meal, serve it with a crisp garden salad tossed in a tangy vinaigrette to balance the creaminess. Roasted or steamed green veggies like broccoli or green beans complement the hearty, savory flavors beautifully. For special occasions, a slice of cornbread makes it extra homey.

Creative Ways to Present

If you’re feeding a crowd or want to offer individual servings, scoop your Loaded Chicken Casserole into ramekins before the final bake for cute, single-serve portions. Or, for game day, serve spoonfuls inside baked potato skins for the ultimate finger food. Let your creativity guide you—this casserole adapts deliciously to your favorite presentation.

Make Ahead and Storage

Storing Leftovers

Leftover Loaded Chicken Casserole stores wonderfully. Simply cover the baking dish tightly with foil or transfer portions to an airtight container and refrigerate for up to 3 days. The flavors meld and deepen, making your next-day meal even tastier.

Freezing

To freeze, let the casserole cool completely, then wrap it (whole or in individual portions) tightly with plastic wrap followed by foil. Freeze for up to 2 months. When you’re ready to enjoy it, thaw overnight in the refrigerator for best results.

Reheating

Reheat leftovers in a 350°F oven, covered with foil, for about 20–25 minutes or until hot throughout. For crispier edges and a bubbly top, remove the foil for the last 5 minutes. The microwave also works for quick lunches—just use a microwave-safe dish and heat in 1-minute increments until warmed through.

FAQs
