Ingredients You’ll Need

Here’s everything you need to bring this dish to life:

For the Base

• 2 tablespoons butter

• 1 medium onion, diced

• 2 cloves garlic, minced

• 1/4 cup all-purpose flour

• 2 cups chicken broth

• 1 cup whole milk

• 1/2 cup heavy cream

• Salt and pepper to taste

• 1 teaspoon dried thyme

• 1/2 teaspoon paprika

• 1/4 teaspoon ground mustard (optional but adds depth)

Protein & Add-Ins

• 3 cups cooked chicken, shredded (rotisserie chicken works great)

• 1 cup frozen peas and carrots (thawed)

• 1 cup cooked mushrooms (optional)

• 1/2 cup sour cream or Greek yogurt

For the Topping

• 1 1/2 cups shredded cheddar cheese

• 1 cup crushed butter crackers or breadcrumbs

• 2 tablespoons melted butter

• Chopped fresh parsley (for garnish)

Step-by-Step Instructions

1. Prepare the Cream Sauce

In a large skillet or saucepan, melt butter over medium heat. Add the diced onions and sauté until they’re soft and translucent, about 5 minutes. Stir in the garlic and cook for another 30 seconds until fragrant.

Sprinkle the flour over the onions and stir to form a roux. Cook for about 1 minute to eliminate the raw flour taste. Slowly whisk in chicken broth, followed by the milk and heavy cream. Stir continuously until the mixture is smooth and begins to thicken—about 5–7 minutes.

Season with salt, pepper, thyme, paprika, and ground mustard. Lower the heat and simmer for a few minutes.

2. Combine with Chicken and Vegetables

In a large mixing bowl, combine the shredded chicken, peas and carrots, and mushrooms (if using). Pour the creamy sauce over the mixture and fold in the sour cream or Greek yogurt until everything is well coated.

3. Assemble the Casserole

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch casserole dish. Pour the creamy chicken mixture into the dish, spreading it evenly.

Sprinkle shredded cheddar cheese over the top.

4. Prepare and Add the Topping

Mix the crushed crackers or breadcrumbs with melted butter until evenly coated. Sprinkle this mixture evenly over the cheese.

5. Bake to Perfection

Bake uncovered for 25–30 minutes, or until the top is golden brown and the casserole is bubbling around the edges. Let it rest for 5–10 minutes before serving.

Garnish with chopped parsley for a touch of freshness and color.

Serving Suggestions

This creamy chicken casserole is a complete meal on its own, but it pairs beautifully with:

• Crisp Green Salad: Light and tangy to contrast the creamy richness.

• Steamed Broccoli or Green Beans: Adds a bit more veggie power.

• Dinner Rolls or Garlic Bread: Perfect for scooping up that sauce.

Make-Ahead and Storage Tips

To Make Ahead:

Assemble the entire casserole (minus the topping) and refrigerate for up to 24 hours. When ready to bake, add the topping and cook as directed.

To Freeze:

Wrap the unbaked casserole tightly in plastic wrap and aluminum foil. Freeze for up to 2 months. To bake from frozen, cover with foil and bake at 375°F for 60–70 minutes, removing foil for the last 15 minutes.

Leftovers:

Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat in the oven or microwave until warmed through.

Tips for the Best Creamy Chicken Casserole

• Use Rotisserie Chicken: Saves time and adds flavor.

• Don’t Skip the Roux: It ensures a smooth, non-runny sauce.

• Add Fresh Herbs: Fresh thyme, parsley, or chives elevate the flavor.

• Balance the Cream: A bit of tangy sour cream or Greek yogurt prevents the dish from feeling too heavy.

Variations to Try

This casserole is wonderfully versatile. Here are a few ways to switch it up:

1. Cheesy Broccoli Chicken Casserole

Swap peas and carrots for steamed broccoli florets and increase the cheese. A blend of sharp cheddar and mozzarella adds gooey richness.

2. Tex-Mex Style

Add black beans, corn, and diced green chiles. Use pepper jack cheese and sprinkle with cilantro for a spicy twist.

3. Low-Carb Option

Replace the flour with almond flour or omit it altogether. Use cauliflower florets instead of pasta or rice if you’re adding starch.

4. Add Pasta or Rice

Mix in cooked pasta (like penne or egg noodles) or rice before baking for a heartier dish. Just reduce the amount of chicken slightly to keep the balance.

FAQs About Creamy Chicken Casserole

Can I use canned soup instead of making the sauce from scratch?
Yes, for a shortcut, you can use one can of cream of chicken soup mixed with 1/2 cup milk. However, the homemade version delivers a far superior flavor.

Is this casserole gluten-free?
It can be! Just substitute the flour with a gluten-free all-purpose blend and use gluten-free breadcrumbs or crackers for the topping.

Can I add bacon?
Absolutely. Crumbled cooked bacon adds a smoky, savory layer that complements the creamy base beautifully.

What’s the best way to reheat it?
For best results, reheat in a 350°F oven covered with foil for 15–20 minutes. This keeps the topping from getting too crunchy or overbaked.
