How to Make Cheesy Mushroom Casserole

Step 1: Prepare the Mushrooms and Aromatics

Start by cleaning and chopping your mushrooms into bite-sized pieces. In a large skillet, melt butter over medium heat and sauté diced onions and garlic until translucent and fragrant. Add the mushrooms and cook until all their moisture has evaporated and they become tender and slightly browned.

Step 2: Mix the Creamy Base

In a mixing bowl, combine cream cheese and sour cream until smooth. Stir in shredded cheddar cheese, then season the mixture with salt and pepper to taste. This creamy blend will become the luscious foundation of your casserole.

Step 3: Combine Ingredients and Transfer to Baking Dish

Fold the sautéed mushroom mixture gently into the cheese mixture until fully incorporated. Pour the combined mixture into a greased casserole dish, spreading it into an even layer to ensure every bite is bursting with flavor.

Step 4: Add Topping and Bake

Sprinkle breadcrumbs evenly over the surface for a crunchy finish. Bake the casserole in a preheated oven at 350°F (175°C) for about 25 to 30 minutes, or until the top is golden brown and bubbly around the edges.

Step 5: Garnish and Serve

Once out of the oven, let it cool for a few minutes before sprinkling with fresh parsley. This garnish adds a fresh, vibrant flavor and a pleasing visual touch to the Cheesy Mushroom Casserole.

Pro Tips for Making Cheesy Mushroom Casserole

• Drain Mushrooms Well: Removing excess moisture prevents a soggy casserole and intensifies mushroom flavor.
• Use Sharp Cheese: A stronger cheese like sharp cheddar adds a tangy richness that complements mushrooms perfectly.
• Don’t Skip the Breadcrumb Topping: It adds texture contrast and an irresistible golden crust.
• Let it Rest: Allow the casserole to cool slightly before serving so it firms up and slices neatly.
• Double the Recipe: This casserole makes a fantastic leftover lunch or potluck dish.

How to Serve Cheesy Mushroom Casserole

Garnishes

Fresh parsley or chives bring a bright, fresh note to balance the creamy richness, while a light sprinkle of smoked paprika can add subtle warmth. Adding a few thinly sliced green onions right before serving warms up the flavors beautifully.

Side Dishes

Pair this casserole with crispy roasted vegetables or a crisp green salad to cut through the richness. It also complements simple grilled chicken or a slice of crusty bread, making for a well-rounded meal.

Creative Ways to Present

For a stunning dinner party touch, serve individual portions in small ramekins topped with extra breadcrumbs and broiled for a minute to get a golden crust. Alternatively, layer the casserole with fresh spinach for a colorful, textured look that invites guests to dig in.

Make Ahead and Storage

Storing Leftovers

Keep any leftover Cheesy Mushroom Casserole in an airtight container in the refrigerator for up to 3 days. It tastes even better once the flavors have had time to meld overnight.

Freezing

This casserole freezes beautifully. Transfer it to a freezer-safe dish, cover tightly with foil, and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.

Reheating

Reheat leftovers in the oven at 325°F (160°C) until warmed through to help restore that crispy breadcrumb topping. Microwaving is faster but may soften the crust.
