Steps to Make Cheesy Mushrooms Casserole

Step 1: Prepare Oven and Dish

Set oven to 375°F and coat a 9×13-inch baking dish with cooking spray or butter to prevent sticking.

Step 2: Season Mushrooms

• Olive oil
• Garlic powder
• Dried thyme
• Salt
• Black pepper

Toss ingredients until mushrooms are evenly coated with seasonings.

Step 3: Arrange Mushroom Layer

Spread seasoned mushrooms uniformly across the prepared baking dish, creating an even base layer.

Step 4: Add Cheese Goodness

• Shredded cheddar cheese
• Grated Parmesan cheese

Ensure complete coverage for maximum cheesy flavor.

Step 5: Create Creamy Base

Pour heavy cream evenly across the entire dish, allowing it to settle between mushroom and cheese layers.

Step 6: Craft Crunchy Topping

Mix melted butter with breadcrumbs until thoroughly combined.

Distribute this mixture across the casserole’s surface for a crispy golden finish.

Step 7: Bake to Perfection

Place casserole in preheated oven and bake for 25-30 minutes until top turns golden brown and sauce bubbles around edges.

Step 8: Final Crisp

Optional: Broil for 2-3 minutes to achieve an extra crispy, slightly charred topping.

Step 9: Rest and Garnish

Allow casserole to rest for 5 minutes.

Sprinkle freshly chopped parsley on top before serving for a pop of color and fresh flavor.

Handy Tips for a Perfect Mushroom Casserole

• Experiment with different cheese combinations like gruyère, mozzarella, or gouda to create unique flavor profiles that complement the earthy mushrooms.
• Pat mushrooms dry before seasoning to prevent excess liquid and ensure a crispy, golden-brown topping without sogginess.
• Toast breadcrumbs in a skillet with butter before sprinkling to enhance their texture and add a rich, nutty flavor to the casserole.
• Substitute heavy cream with coconut milk for a dairy-free version, or use gluten-free breadcrumbs to make the dish suitable for various dietary restrictions.
• Add fresh thyme or rosemary alongside parsley for an extra layer of aromatic complexity that brightens the entire dish.

Best Way to Store and Reheat Mushroom Casserole

• Store leftover casserole in an airtight container for up to 3-4 days, keeping it fresh and tasty in the refrigerator.
• Warm slices at 350°F for 10-15 minutes, covering with foil to prevent drying out and maintain the creamy texture.
• Heat individual portions for 1-2 minutes, stirring halfway through to ensure even warming and preserve the mushroom's delicate flavor.
• Wrap tightly in plastic wrap and freeze for up to 1 month, thawing overnight in the refrigerator before reheating for best results.

What to Serve with Cheesy Mushrooms Casserole

• Unleash Red Wine Magic: Select a robust Pinot Noir or earthy Burgundy that complements the mushroom's deep, umami flavors and cuts through the creamy cheese richness.
• Craft the Perfect Protein Partner: Serve alongside roasted chicken with herbs or grilled medium-rare steak to create a balanced, satisfying meal that elevates the casserole's savory profile.
• Create Fresh Salad Contrast: Prepare a crisp arugula salad with lemon vinaigrette and toasted pine nuts to provide a bright, tangy counterpoint to the dense, creamy casserole texture.
• Enhance with Crusty Bread: Add warm, crusty sourdough or French baguette slices to soak up the delicious cheesy cream sauce, creating an irresistible dining experience.

Flavor Variations for Cheesy Mushrooms Casserole

• Dairy-Free Delight: Swap heavy cream with coconut milk and use nutritional yeast instead of cheese for a vegan-friendly version that maintains rich, creamy flavor.
• Gluten-Free Option: Replace traditional breadcrumbs with crushed gluten-free crackers or almond flour to create a crispy topping while keeping the dish celiac-friendly.
• Protein Power Boost: Add cooked diced chicken or crumbled bacon between mushroom layers to transform the casserole into a more substantial main course with extra protein.
• Herb Garden Remix: Experiment with different herb combinations like rosemary, sage, or basil instead of thyme to create unique flavor profiles that complement the mushrooms' earthy taste.

Instructions

1. Prepare the oven environment by heating to 375°F (190°C) and coating a 9×13-inch baking dish with a light layer of grease.
2. Create a flavor foundation by combining sliced mushrooms with olive oil, garlic powder, thyme, salt, and pepper, ensuring each mushroom slice is thoroughly seasoned.
3. Distribute the aromatic mushroom mixture uniformly across the prepared baking dish, creating an even layer.
4. Enhance the dish’s richness by generously scattering shredded cheddar and grated Parmesan cheese over the mushroom layer.
5. Delicately cascade heavy cream across the entire surface, allowing it to seep between the mushrooms and cheese.
6. Craft a crispy topping by blending melted butter with breadcrumbs until achieving a consistent, crumbly texture.
7. Sprinkle the butter-infused breadcrumb mixture evenly over the cheese and cream-covered mushrooms, creating a golden, textured crown.
8. Transfer the casserole to the preheated oven and bake for 25-30 minutes, watching for a beautifully golden-brown surface and bubbling sauce.
