Ingredients
- 1 1/2 pounds cremini or white mushrooms (cleaned and sliced)
- 3 tablespoons unsalted butter
- 1 medium onion (chopped)
- 3 cloves garlic (minced)
- 1/2 teaspoon salt
- 1/2 teaspoon black pepper
- 1 teaspoon dried thyme
- 1/2 teaspoon dried oregano
- 1 cup Italian-style breadcrumbs
- 1 cup shredded mozzarella cheese

- 1/2 cup heavy cream
- 1/4 cup chopped fresh parsley (for garnish)
Instructions
Step 1: Preheat the Oven
- Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish or a similar-sized casserole dish with cooking spray or butter.
Step 2: Cook the Mushrooms
- In a large skillet over medium heat, melt the butter. Add the chopped onion and sauté for about 5 minutes, or until softened.
- Add the sliced mushrooms to the skillet and cook for another 8-10 minutes, or until the mushrooms have released their moisture and are golden brown.
- Stir in the minced garlic, salt, black pepper, thyme, and oregano. Cook for another 1-2 minutes, until fragrant.
Step 3: Assemble the Casserole
- Transfer the mushroom mixture to the prepared baking dish.
- In a bowl, mix together the Italian-style breadcrumbs, mozzarella cheese, and Parmesan cheese.
- Sprinkle the breadcrumb and cheese mixture evenly over the mushrooms.
- Drizzle the heavy cream over the top of the casserole.
Step 4: Bake
- Bake in the preheated oven for 25-30 minutes, or until the top is golden brown and bubbly.
Step 5: Garnish and Serve
- Remove from the oven and let cool for 5 minutes.
- Garnish with chopped fresh parsley and serve warm as a side dish or main course.
Cooking Notes
- Mushrooms: Cremini or white mushrooms work well for this casserole, but you can also use a mix of mushrooms, such as shiitake or portobello, for added depth of flavor.
- Cheese: Mozzarella adds a melty, creamy texture, but you could also use Gruyere or fontina for a richer flavor.
- Breadcrumbs: Italian-style breadcrumbs add extra flavor, but plain breadcrumbs will work just as well. You can also make your own by toasting and seasoning leftover bread.
Variations
Sausage-Stuffed Mushroom Casserole
- Add 1/2 pound of cooked Italian sausage to the mushroom mixture before assembling the casserole for a heartier dish.
Spinach and Mushroom Casserole
- Stir in 2 cups of fresh spinach leaves with the mushrooms until wilted for added greens and flavor.
Vegan Stuffed Mushroom Casserole
- Use vegan butter, a non-dairy cream alternative, and dairy-free cheese to make this casserole vegan-friendly.
