Instructions Step-by-Step Creamy Chicken and Mushroom Casserole
1. Preheat Your Oven
Start by preheating your oven to 350°F (175°C). This ensures your casserole will bake evenly and thoroughly.
2. Sauté the Vegetables
In a large skillet, heat the olive oil over medium heat. Add the chopped onion and sliced mushrooms, cooking until they’re tender (about 5-7 minutes). Stir in the minced garlic and cook for an additional minute until fragrant.
3. Prepare the Sauce
Pour in the heavy cream and chicken broth, stirring to combine. Season with salt and pepper to taste. Allow the mixture to simmer for about 5 minutes until slightly thickened.
4. Combine Ingredients
In a large mixing bowl, combine the cooked chicken, sautéed vegetables, cooked rice, and half of the cheddar cheese. Mix until everything is coated with the creamy sauce.
5. Assemble the Casserole
Transfer the mixture into a greased 9×13 inch baking dish. Top with the remaining cheddar cheese, spreading it evenly over the top.
6. Bake & Serve
Bake in your preheated oven for 30 minutes, or until the cheese is bubbly and golden. Once it’s done, remove from the oven and let it sit for a few minutes before serving. Garnish with fresh parsley if desired!
