Detailed Recipe Steps
Now, let’s dive into the cooking process. Follow these detailed steps to make your casserole:
- Preheat Your Oven: Start by preheating your oven to 350°F (175°C). This ensures that your casserole cooks evenly.
- Sauté the Vegetables: In a large skillet, heat 2 tablespoons of olive oil and 1 tablespoon of butter over medium heat. Once melted, add the chopped onion, minced garlic, diced celery, and carrots. Sauté for about 5-7 minutes, or until the vegetables are tender.
- Add the Mushrooms: Stir in the sliced mushrooms and continue cooking for another 3-4 minutes until they become soft and fragrant.
- Mix the Filling: In a large mixing bowl, combine the cooked chicken, sautéed vegetables, frozen peas, cream of mushroom soup, chicken broth, thyme, parsley, salt, and pepper. Mix everything well to ensure all ingredients are evenly coated.
- Assemble the Casserole: Pour the chicken mixture into a greased 9×13 inch baking dish, spreading it out evenly.
- Add Cheese: Sprinkle the shredded cheddar cheese generously over the top of the chicken mixture. This will create a delicious, cheesy crust.
- Prepare the Breadcrumb Topping: In a small bowl, combine the breadcrumbs with an additional tablespoon of melted butter. Mix well and sprinkle this mixture evenly over the cheese layer.
- Bake the Casserole: Cover the baking dish with aluminum foil and place it in the preheated oven. Bake for 25 minutes. After this time, remove the foil and bake for an additional 15-20 minutes, or until the casserole is bubbly and the breadcrumbs are golden brown.
- Cool and Serve: Once baked, allow the casserole to cool for a few minutes before serving. This will help it set and make it easier to serve. Enjoy your Chicken Mushroom Casserole!
