Step‑by‑Step Instructions for Creamy Chicken Mushroom Casserole

Step 1: Prepare Chicken
Begin by seasoning the chicken strips generously with sea salt and black pepper. Dredge the seasoned chicken in all-purpose flour until thoroughly coated. In a large skillet, heat a splash of olive oil over medium-high heat. Add the chicken strips to the pan and sauté for 3-4 minutes on each side, or until they are golden brown and cooked through. Remove the chicken from the skillet and set aside.

Step 2: Sauté Vegetables
In the same skillet, add a bit more olive oil if needed, then toss in the thick-sliced mushrooms and diced onion. Sauté for about 7-8 minutes until the vegetables become softened and golden. In the last minute of cooking, add minced garlic, stirring continuously until fragrant and its aroma fills the kitchen. This step is crucial for building flavor in your Creamy Chicken Mushroom Casserole.

Step 3: Make Sauce
Reduce the heat to medium and add butter to the skillet, allowing it to melt. Whisk in a couple of tablespoons of flour to create a roux, cooking for about 1-2 minutes until bubbly. Gradually pour in chicken broth while continuously whisking to prevent lumps. Next, mix in fresh lemon juice and half and half. Let the sauce simmer for around 3-5 minutes until it thickens and becomes creamy.

Step 4: Assemble
Layer the sautéed mushrooms and onions evenly over the cooked chicken in a large casserole dish. Pour the luscious sauce over the top, ensuring everything is well covered. Use a spatula to gently spread the sauce, allowing it to seep into the layers. Cover the casserole with aluminum foil to retain moisture during baking, which is crucial for achieving that comforting texture in your Creamy Chicken Mushroom Casserole.

Step 5: Bake
Preheat your oven to 350°F (175°C) and place the covered casserole dish on the middle rack. Bake for 45 minutes, removing the foil in the last 5-10 minutes to let the top gently brown and bubble. The casserole is done when the sauce is creamy and the chicken is heated through. Allow it to rest for a few minutes before serving, garnished with fresh parsley or thyme for added color and freshness.

Storage Tips for Creamy Chicken Mushroom Casserole

Freezer: Wrap the casserole tightly in plastic wrap, then aluminum foil. It can be frozen for up to 2-3 months. Thaw in the fridge overnight before reheating.

Reheating: To reheat, place the casserole in a preheated oven at 350°F for about 20-30 minutes, or until heated through. Feel free to add a splash of broth or cream if the sauce thickens too much.

Expert Tips for Creamy Chicken Mushroom Casserole

Don’t Overcrowd the Pan: When sautéing the chicken, make sure not to crowd the skillet. This ensures a beautiful sear instead of steaming the meat.
Add Extra Herbs: For a burst of flavor, consider adding additional herbs like thyme or rosemary into the sauce. It enhances the overall profile of your Creamy Chicken Mushroom Casserole.
Prep Ahead: If you want to save time later, assemble the casserole a day in advance. Just bake it the next day, allowing extra time if it’s coming from the fridge.
Watch for Thickness: Keep an eye on the sauce while it simmers. If it’s too thick for your liking, whisk in a bit more chicken broth to achieve your desired consistency.
Garnish for Freshness: Always remember to sprinkle fresh parsley or thyme on top before serving. It adds color and a hint of freshness to your comforting casserole.

To store your leftovers, wait until the casserole has cooled completely, then transfer it to an airtight container. It can stay fresh in the fridge for up to 3 days.

When you’re ready to enjoy it, thaw it overnight in the refrigerator and then reheat it in the oven at 350°F (175°C) for about 20-25 minutes until heated through.

What is the best way to reheat the casserole?
For the best results, reheat your Creamy Chicken Mushroom Casserole in the oven at 350°F (175°C) for around 20-25 minutes, covered with foil to retain moisture.
