How to Make Mushroom Gruyere Chicken and Rice Casserole
Step 1: Sauté the Vegetables
Heat butter and olive oil in a skillet over medium heat. Add onions and mushrooms and cook until softened and lightly golden. Stir in garlic and cook for 30 seconds.
Step 2: Build the Casserole Base
In the baking dish, add uncooked rice, cooked chicken, sautéed vegetables, salt, pepper, thyme, and paprika. Stir gently to combine.
Step 3: Add Liquids
Pour in the chicken broth and heavy cream, stirring so everything is evenly distributed.
Step 4: Add the Cheese
Sprinkle Gruyere evenly over the top. Don’t stir—this creates a beautiful cheesy layer.
Step 5: Bake
Cover tightly with foil and bake at 375°F (190°C) for 40 minutes. Remove foil and bake another 15–20 minutes until the rice is tender and the top is golden.
Step 6: Rest and Garnish
Let the casserole rest for 5–10 minutes before serving. Garnish with fresh parsley.
