How to Make 3-Ingredient Chicken à la King Casserole
1. Prepare the Oven
Preheat your oven to 350°F (175°C). Lightly grease a 2-quart casserole dish.
2. Combine the Ingredients
Add the cooked chicken, condensed cream of chicken soup, and drained mushrooms with pimientos to a large mixing bowl.
Stir gently until everything is thoroughly combined and the chicken is evenly coated in the creamy sauce.
3. Transfer to the Casserole Dish
Spoon the mixture into the prepared baking dish and spread it into an even layer.
4. Bake
Bake uncovered for 30–35 minutes, or until the casserole is hot and bubbling around the edges with a lightly golden top.
5. Rest and Serve
Allow the casserole to rest for about 5 minutes before serving. This gives the creamy sauce a moment to settle.
Serve it over toast points, rice, biscuits, or buttered egg noodles for a hearty meal.
Helpful Tips
Add a crispy topping: For extra texture, sprinkle buttered breadcrumbs or crushed buttery crackers over the casserole before baking.
Use leftover turkey: Replace the chicken with cooked turkey for an easy post-holiday casserole.
Thin the sauce if needed: If the mixture seems too thick, stir in 2–4 tablespoons of milk before baking.
Serve it over a starch: Toast, rice, biscuits, or egg noodles help soak up the creamy sauce and make the casserole more filling.
Make it ahead: Assemble the casserole several hours in advance, cover, and refrigerate. Let it sit at room temperature for about 20 minutes before baking, then add a few extra minutes to the cooking time.
