How to Make Stuffed Mushroom Casserole
-
Preheat the oven to 350°F (175°C). This sets the perfect temperature for creating that golden, crispy topping you’re looking for.
-
Heat olive oil in a large skillet over medium heat. This will provide a rich base for the sautéed mushrooms, enhancing their flavor.
-
Sauté quartered mushrooms with salt and pepper until they become soft and the liquid has mostly evaporated. This should take about 7-9 minutes; the mushrooms will turn a lovely golden brown.
-
Add minced garlic to the skillet and sauté for around 1 minute until fragrant. The aroma of garlic will fill your kitchen, hinting at the deliciousness to come!
-
Stir in cream cheese until the mushrooms are well coated. The cream cheese will melt into a creamy mixture, enveloping the mushrooms in rich flavor.
-
Remove from heat and gently mix in mozzarella cheese, half of the breadcrumbs, and a quarter of the parmesan. This will create a delectable filling for your casserole.
-
Transfer the mixture to a greased 8×8-inch baking dish. Ensure it’s spread evenly for consistent cooking and that perfect topping crunch.
-
Combine parsley, melted butter, remaining breadcrumbs, and parmesan in a separate bowl. This will be your crunchy topping, adding texture and flavor.

Top the casserole with the breadcrumb mixture, making sure to cover it evenly. This will create a beautiful crust while baking.

Preparing the Stuffed Mushroom Casserole ahead of time is a fantastic way to save time during busy weeknights. You can sauté the mushrooms and mix in the cream cheese up to 24 hours in advance, then refrigerate the filling in an airtight container. On the day of serving, simply transfer the mixture to the baking dish, add the breadcrumb topping, and pop it in the oven. If desired, you can also prepare the entire casserole and refrigerate it for up to 3 days before baking. To maintain that delightful texture, cover it tightly to prevent drying out. When you’re ready to enjoy, bake straight from the fridge, adding an extra 5-10 minutes to the cooking time for a delicious meal with minimal effort!
