How to Make Baked Cheesy Mushroom Casserole

Step 1: Prepare the veggies

Start by cleaning and slicing your mushrooms, then sauté them with minced garlic and chopped onions in butter until they’re tender and golden. This step unlocks the mushrooms’ rich flavor and softens the onions.

Step 2: Make the creamy cheese mixture

In a separate bowl, combine heavy cream or sour cream with shredded cheese, salt, pepper, and your fresh herbs. Stir until everything is smoothly blended and ready to enrich the casserole.

Step 3: Combine all ingredients

Mix the sautéed mushrooms and onions into the cheese mixture, ensuring each piece is coated with creamy goodness. This mix forms the savory filling of the casserole.

Step 4: Assemble and top

Spread the mixture evenly in a greased casserole dish, then sprinkle breadcrumbs and a bit more shredded cheese on top to create a golden crust when baked.

Step 5: Bake until bubbly

Bake the casserole in a preheated oven at 350°F (175°C) for 25 to 30 minutes, or until the top is bubbly and golden brown. Let it cool a little before serving for the best texture.

Pro Tips for Making Baked Cheesy Mushroom Casserole

• Use fresh mushrooms: They release less water when cooked, preventing sogginess in your casserole.
• Don’t skip the sautéing: Cooking mushrooms and onions first deepens the flavor of the dish.
• Choose a combination of cheeses: Mixing sharper and milder cheeses adds complexity and creaminess.
• Let it rest before serving: This helps the casserole set and makes slicing easier.
• Season carefully: Taste your cheese mixture before baking to adjust salt and pepper perfectly.

How to Serve Baked Cheesy Mushroom Casserole

Garnishes

Finishing with freshly chopped parsley or thyme adds a pop of color and fresh flavor, perfectly complementing the richness of the casserole.

Side Dishes

Serve with a crisp green salad or garlic roasted vegetables to balance the creamy casserole. Crusty bread or buttery mashed potatoes make excellent companions for a full comfort meal.

Creative Ways to Present

For a festive touch, serve the casserole in individual ramekins or small cast-iron skillets. You can also sprinkle toasted nuts or a drizzle of truffle oil on top for an elevated flavor profile.

Make Ahead and Storage

Storing Leftovers

Keep leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently to maintain the creamy texture without drying out.

Freezing

This casserole freezes well; place it in a freezer-safe dish and freeze for up to 2 months. Thaw overnight in the fridge before reheating for best results.

Reheating

Reheat in the oven at 325°F (160°C) until warmed through and bubbly again. Avoid microwaving, which can make the texture rubbery.

FAQs

Can I use canned mushrooms instead of fresh?

Fresh mushrooms are best because they hold up better when baked, but if you must use canned, drain them thoroughly to prevent excess moisture.

Is this casserole gluten-free?

Not by default due to the breadcrumbs, but you can easily swap in gluten-free breadcrumbs or crushed nuts to make it gluten-free.

Can I prepare this casserole in advance?

Yes! Assemble it and refrigerate for up to 24 hours before baking to save time on a busy day.

What type of cheese works best?

Sharp cheddar is a classic choice, but mixing cheddar with mozzarella or gruyere enhances creaminess and flavor complexity.

How can I make this recipe vegan?

Use dairy-free cheese, plant-based cream, and vegan butter, and substitute breadcrumbs with gluten-free or vegan-friendly options.
