How to Make Chicken Casserole

Step 1: Preheat

Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or non-stick spray.

Step 2: Sauté the Vegetables

In a large skillet, melt 3 tablespoons butter over medium heat. Add the onions, garlic, carrots, and celery. Cook for 5–7 minutes, until they soften and become fragrant. This builds the base flavor of your casserole.

Step 3: Make the Creamy Sauce

Sprinkle the flour over the cooked vegetables and stir to coat. This forms a roux, crucial for thickening the sauce.

Slowly pour in the chicken broth while whisking to prevent lumps. Once the mixture begins to thicken, add the heavy cream. Stir in the thyme, parsley, paprika, salt, and pepper. Let the sauce simmer for 3–5 minutes until creamy and smooth.

Step 4: Add Chicken and Peas

Add the shredded chicken and frozen peas into the skillet, stirring until everything is evenly coated in the sauce.

Step 5: Assemble the Casserole

Transfer the creamy chicken mixture into the prepared baking dish. Sprinkle the cheddar cheese evenly over the top.

Step 6: Add the Topping

In a small bowl, mix the crushed crackers (or bread crumbs) with 2 tablespoons melted butter. Sprinkle this mixture over the casserole to create a golden, crispy crust.

Step 7: Bake

Bake for 25–30 minutes, or until the top is golden brown and the casserole is bubbling around the edges.

Step 8: Rest and Serve

Let it sit for 5–10 minutes. This helps the casserole set and makes serving easier.

Serve warm and enjoy the creamy, cheesy, buttery goodness!

Tips for the Best Chicken Casserole

• Use cooked chicken: Rotisserie chicken is quick and flavorful.

• Don’t skip the roux: It makes the sauce thick and velvety.

• Taste the sauce: Adjust salt and pepper before baking.

• Add starch: Mix in cooked pasta or rice to make it heartier.

• Crispy topping: Ritz crackers create the best crunch, but panko works too.
