Ingredients

1 ½ pounds cremini or baby bella mushrooms

8 ounces cream cheese, softened

1 cup shredded mozzarella cheese

½ cup grated Parmesan cheese

3 cloves garlic, minced

1 small onion, finely chopped

2 tablespoons butter

1 tablespoon olive oil (plus more for topping)

1 cup panko breadcrumbs

2 tablespoons fresh parsley, chopped

½ teaspoon salt

¼ teaspoon black pepper


Instructions

1. Clean mushrooms with a damp paper towel and remove stems. Slice larger mushrooms in half if necessary.

2. In a large skillet, heat butter and olive oil over medium heat. Sauté onion until translucent, then add garlic and cook for 30 seconds more.

3. Add chopped mushroom stems, salt, and pepper. Cook until tender, about 5–6 minutes.

4. Remove from heat. Stir in cream cheese, ½ cup mozzarella, and ¼ cup Parmesan until smooth.

5. Preheat oven to 375°F (190°C). Grease a baking dish and spread a thin layer of filling on the bottom.

6. Arrange mushroom caps open-side up in the dish. Spoon filling over and around the mushrooms.

7. Top with remaining mozzarella and Parmesan.

8. Toss panko breadcrumbs with a drizzle of olive oil and a pinch of salt. Sprinkle over the casserole.

9. Bake uncovered for 25–30 minutes until golden and bubbling.

10. Broil for 2–3 minutes if needed for a crispier topping.

11. Let rest for 5 minutes before garnishing with fresh parsley and serving hot.

Notes

Use room temperature cream cheese for easier mixing and smoother texture.

Don’t skip broiling—it adds a crunchy, golden top layer.

Make-ahead friendly: Assemble the night before and bake the next day.
