Ingredients
- 1 lb button mushrooms, sliced
- 1 tbsp olive oil
- 1 tsp garlic powder
- 1 tsp dried thyme
- 1/2 tsp salt
- 1/4 tsp black pepper
- 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)
- Fresh parsley, chopped (for garnish)
Instructions
1. Preheat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.
2. In a large bowl, toss the sliced mushrooms with olive oil, garlic powder, dried thyme, salt, and black pepper until evenly coated.
3. Spread the seasoned mushrooms evenly into the prepared baking dish.
4. Sprinkle the shredded cheddar and grated Parmesan cheese evenly over the mushrooms.
5. Pour the heavy cream evenly over the entire casserole.
6. In a small bowl, combine the melted butter and breadcrumbs until well mixed, then sprinkle the mixture evenly over the top.
7. Bake for 25 to 30 minutes, or until the top is golden brown and the sauce is bubbling.
8. For an extra crispy topping, broil for an additional 2 to 3 minutes, watching carefully to prevent burning.
9. Remove from the oven and let rest for a few minutes before garnishing with freshly chopped parsley and serving.
Notes
For a lower-carb version, omit the breadcrumbs or substitute them with crushed nuts.
You can add sautéed onions or spinach for extra flavor and texture.
Allowing the casserole to rest briefly helps the sauce thicken before serving.
