Ingredients You’ll Need for Chicken and Mashed Potatoes Casserole
To make this comforting casserole, you only need a handful of ingredients that are commonly found in your kitchen. Here’s everything you’ll need:
- 6 tablespoons unsalted butter, divided
- 1 pound boneless skinless chicken breasts, cut into 1-inch cubes
- Salt and pepper to taste
- 8 ounces fresh mushrooms, sliced
- 2 large garlic cloves, minced
- 2 tablespoons flour
- ¾ cup milk
- 1 cup chicken broth
- 1 cup diced bell pepper (any color or combination)
- 3 cups mashed potatoes
How to Make Chicken and Mashed Potatoes Casserole
Step 1: Preparing the Chicken
Begin by seasoning your chicken cubes with salt and pepper. Melt 2 tablespoons of butter in a large skillet over medium-high heat, then sauté the chicken until it’s fully cooked, about 10 minutes. Transfer the chicken to a separate bowl and set it aside.
Step 2: Cooking the Vegetables
In the same skillet, melt another 2 tablespoons of butter over medium heat. Add the sliced mushrooms and cook them for 3-4 minutes until tender. Then, add the remaining butter and minced garlic, cooking for about 30 seconds until fragrant.
Step 3: Making the Sauce
Sprinkle the flour over the garlic and mushrooms, stirring constantly for about a minute until the flour turns golden. Gradually whisk in the milk and chicken broth until the sauce is smooth. Season with salt and pepper to taste.
Step 4: Combining Ingredients
Return the cooked chicken to the skillet and add the diced bell peppers. Mix everything thoroughly, ensuring the chicken is coated with the creamy mushroom sauce. Allow it to simmer for 2 minutes, then turn off the heat.
Step 5: Preparing for Baking
Preheat your oven to 350°F (175°C). Spread the mashed potatoes evenly over the chicken and sauce mixture. Use the back of a spoon to level the top, and create decorative lines or patterns with a fork if desired.
Step 6: Baking the Casserole
Place the skillet in the middle rack of your oven and bake for 45 minutes, or until the mashed potato topping turns golden brown. This creates a satisfying crunch on top while keeping the sauce underneath creamy and rich.
By following these steps, you’ll have a casserole that is both flavorful and comforting. The process is simple, and the result is a dish that will impress anyone at your dinner table.
How to Serve Chicken and Mashed Potatoes Casserole
Serving this casserole is as simple as baking it. Once golden and bubbly, let it cool for a few minutes before serving. This will help the sauce settle and make it easier to portion out. You can serve it straight from the skillet, creating a rustic, homey presentation that’s perfect for family dinners.
Pair the casserole with a light side salad or steamed vegetables to add freshness to the meal. You can also sprinkle fresh herbs, like parsley or chives, on top of the mashed potatoes for a touch of color and flavor. Individual servings can be placed on plates, ensuring everyone gets a generous portion of chicken, sauce, and mashed potatoes in each bite.
For a casual dinner, serve it with a side of crusty bread to soak up any extra sauce. The creamy texture of the dish pairs wonderfully with the crunch of bread or a simple vegetable side, making it a complete and satisfying meal.
Expert Tips for Making the Perfect Chicken and Mashed Potatoes Casserole
- Choosing the Right Chicken: Boneless, skinless chicken breasts work well for this recipe, but you can also use chicken thighs or tenders for more flavor and juiciness. If you have leftover cooked chicken, it can be added directly, skipping the initial sauté step.
- Creamy Sauce Tips: For a richer sauce, use half-and-half or heavy cream instead of milk. If you prefer a lighter option, milk works perfectly. Make sure to whisk the sauce thoroughly to prevent lumps and achieve a smooth consistency.
- Vegetable Variations: While bell peppers are used here, you can add peas, zucchini, or green beans. Keep in mind that adding vegetables with high water content may slightly change the consistency of the sauce.
- Mashed Potato Topping: Store-bought mashed potatoes are convenient, but homemade mashed potatoes give a richer flavor. You can also add cheese to the topping for extra indulgence.
- Browning Tips: The mashed potato layer should be golden for a crunchy top. If you prefer a softer top, remove it from the oven before it browns completely.
- Time-Saving Options: If you’re short on time, prepare the chicken and sauce a day ahead, then assemble and bake the casserole when needed. This allows the flavors to meld beautifully while reducing active cooking time on the day of serving.
How to Store Chicken and Mashed Potatoes Casserole
Leftovers from this casserole store well in the refrigerator for 3-4 days. Allow the dish to cool completely before covering it with foil or placing it in an airtight container.
To reheat, use either a microwave or oven. If using the oven, cover the casserole with foil to prevent the mashed potato topping from burning, and heat at 350°F (175°C) until warmed through. In the microwave, reheat individual portions until hot, stirring occasionally to distribute the sauce evenly. Proper storage ensures you can enjoy this comforting dish without sacrificing its creamy texture or flavor.
Variations of Chicken and Mashed Potatoes Casserole
You can easily adapt this recipe to suit different tastes or dietary preferences. For example, add a layer of cheese between the chicken and mashed potatoes for a cheesy casserole. Experiment with different types of mushrooms or include more colorful vegetables like carrots and corn for added texture and nutrition.
For a lighter version, substitute half of the butter with olive oil and use skim milk instead of whole milk. You can also swap chicken for turkey or even a vegetarian protein, using a creamy vegetable sauce to replicate the same comforting flavors.
Another fun twist is to create individual servings using small ramekins. This allows for portion control and makes the dish more elegant for dinner parties. Leftovers can also be frozen for future meals; simply wrap portions tightly in foil and store in the freezer for up to two months. Reheat slowly to maintain the creamy texture.
