Ingredients:
- 1 lb button mushrooms, sliced
- 1 tbsp olive oil
- 1 tsp garlic powder
- 1 tsp dried thyme
- 1/2 tsp salt (or to taste)
- 1/4 tsp black pepper (or to taste)
- 1 cup shredded cheddar cheese
- 1/2 cup grated Parmesan cheese
- 1 cup heavy cream
- 2 tbsp unsalted butter, melted
- 1/2 cup breadcrumbs (optional, for topping)
- 1 tbsp fresh parsley, chopped (for garnish)
Instructions:
Step 1: Preheat and Prepare the Dish
- Begin by preheating your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with butter or non-stick spray to ensure an easy release after baking.
Step 2: Season the Mushrooms
- In a large mixing bowl, combine the sliced mushrooms with the olive oil, garlic powder, dried thyme, salt, and black pepper. Toss everything together until the mushroom slices are evenly and thoroughly coated with the seasonings and oil.
Step 3: Assemble the First Layers
- Transfer the seasoned mushroom mixture to the prepared baking dish, spreading them out into a single, even layer across the bottom. Sprinkle the shredded cheddar and grated Parmesan cheese evenly over the mushrooms, creating a uniform cheesy layer.
Step 4: Add the Cream and Topping
- Pour the heavy cream evenly over the mushrooms and cheese. In a small separate bowl, stir together the melted butter and breadcrumbs until the breadcrumbs are fully moistened. Sprinkle this breadcrumb mixture evenly over the entire surface of the casserole.
Step 5: Bake to Perfection
- Place the baking dish in the preheated oven and bake for 25-30 minutes, or until the top is a deep golden brown and the sauce is bubbling vigorously around the edges.
Step 6: Broil for Crispiness (Optional)
- For an extra crispy and deeply browned top, switch your oven to the broil setting for the final 2-3 minutes of cooking. Watch it closely during this time to prevent the topping from burning.
Step 7: Rest and Garnish
- Remove the bake from the oven and let it rest for 5-10 minutes. This allows the sauce to thicken slightly, making it easier to serve. Garnish with freshly chopped parsley just before serving to add a fresh, colorful finish.
Tips:
- Mushroom Variety: For a more complex flavor, use a blend of mushrooms such as cremini, shiitake, and oyster mushrooms instead of just button mushrooms.
- Prevent Sogginess: Ensure your mushrooms are clean and dry before slicing and seasoning to avoid excess water in the bake.
- Fresh Herbs: If you have them, one teaspoon of fresh thyme leaves will provide a more vibrant flavor than dried.
- Add Protein: For a non-vegetarian version, cooked, diced chicken or turkey can be layered in with the mushrooms before adding the cheese.
Storage Options:
- Refrigerator: Store leftovers in an airtight container in the refrigerator for up to 3 days.
- Reheating: Reheat portions in the microwave until warm, or for a crisper top, reheat in a 350°F (175°C) oven for 10-15 minutes.
- Freezing: It is not recommended to freeze this dish, as the creamy sauce may separate and the mushrooms can become watery upon thawing.
This Cheesy Mushroom Bake is a testament to how simple ingredients can be transformed into something truly special. Its creamy, savory, and comforting nature makes it a dependable and delicious choice for any occasion. Enjoy!
