How to Make Cheesy Mushroom Casserole

Step 1: Prepare the Mushrooms

Start by cleaning and slicing your mushrooms. Heat butter in a large skillet and sauté the mushrooms with chopped garlic and onions on medium heat until they release their moisture and become golden brown—this intensifies the savory flavor.

Step 2: Make the Cheese Sauce

In a separate saucepan, melt cream cheese with milk or cream while stirring continuously. Add shredded cheese little by little until you reach a smooth, creamy consistency. Season with salt, pepper, and fresh herbs to taste.

Step 3: Combine and Assemble

Mix the sautéed mushrooms into the cheese sauce gently. Transfer this mixture into a greased baking dish, smoothing it evenly. Sprinkle breadcrumbs or crushed crackers over the top for a crunchy crust.

Step 4: Bake to Perfection

Place the casserole in a preheated oven at 350°F (175°C) and bake for about 15-20 minutes. Bake until the top is golden and bubbly, signaling that everything is perfectly cooked and ready to enjoy.

Pro Tips for Making Cheesy Mushroom Casserole

• Use Fresh Mushrooms: Avoid pre-sliced or canned mushrooms for the best texture and flavor.
• Don’t Overcrowd the Pan: Give mushrooms space while sautéing to avoid steaming, which results in sogginess.
• Grate Cheese Fresh: Freshly grated cheese melts better and enhances the dish’s creaminess.
• Let It Rest: Allow the casserole to cool for a few minutes before serving to let flavors meld.
• Mix Herbs Carefully: Add fresh herbs towards the end of cooking to keep their vibrant aroma intact.

Creative Ways to Present

Make Ahead and Storage

Storing Leftovers

Cool the casserole completely before storing it in an airtight container in the refrigerator. It will keep well for 3 to 4 days, making it perfect for weekday lunches.

For longer storage, freeze the casserole in a freezer-safe dish or container for up to 2 months. Thaw overnight in the fridge before reheating.

Reheating

Reheat leftovers covered in the oven at 325°F (160°C) until warmed through to maintain the creamy texture, or microwave in short bursts while stirring if in a hurry.
