Breadcrumbs – Creates a crunchy topping; gluten-free breadcrumbs can be used if needed.
Garlic – Fresh garlic elevates flavor, while garlic powder works as an alternative.

Step‑by‑Step Instructions for Stuffed Mushroom Casserole

Step 1: Sauté Aromatics
Begin by heating 2 tablespoons of butter in a large skillet over medium heat. Once melted, add 1 chopped onion and 2 minced garlic cloves. Sauté for about 4-5 minutes until the onions are soft and fragrant, creating a delightful aroma that fills your kitchen.

Step 2: Prepare Mushrooms
Next, add 8 cups of chopped mushrooms—using a mix of button and cremini—to the skillet. Cook for 8-10 minutes until the mushrooms release their liquid and it evaporates. The mushrooms should become tender and most of the moisture should be gone, ensuring a rich flavor for your Stuffed Mushroom Casserole.

Step 3: Mix Filling
In a large mixing bowl, combine the sautéed mushroom mixture with 8 ounces of cream cheese, 1 cup of shredded cheese, 1 cup of breadcrumbs, and a sprinkle of salt, pepper, and any desired herbs. Mix gently until everything is well combined but don’t overdo it; you want to retain a bit of texture for the filling.

Step 4: Assemble Casserole
Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking dish with butter. Spoon the creamy mushroom mixture into the dish, spreading it evenly. If desired, top with an extra sprinkle of breadcrumbs and shredded cheese for a crunchy, golden topping that enhances the Stuffed Mushroom Casserole.

Step 5: Bake
Place the assembled casserole in the preheated oven and bake for about 30 minutes. Keep an eye on it; you’ll know it’s ready when the cheese is bubbly and golden brown on top. This step allows all the delicious flavors to meld together beautifully.

Step 6: Serve
Once baked, remove the casserole from the oven and let it cool for about 5-10 minutes before serving. This brief cooling period helps the filling set a little more, ensuring a perfect slice. Your Stuffed Mushroom Casserole is now ready to bring heartwarming comfort to your table!
