The Story Behind This Casserole

Let me guess. You’ve made stuffed mushrooms before.

They look beautiful. They taste incredible. But halfway through stuffing them, you start questioning your life choices.

That’s exactly how this casserole was born.

One holiday season, I had extra mushroom filling left over. Instead of stuffing more caps, I spread everything into a baking dish, topped it with breadcrumbs and cheese, and baked it.

The result? An accidental masterpiece.

It tasted like an Unstuffed Mushroom dream. All the flavor. None of the tedious prep.

Since then, this has become my go-to Mushroom Casserole Dinner when I want something comforting but impressive.

Ingredients Breakdown: Why Each One Matters

Let’s break this down so you understand exactly what makes this dish sing.

White Mushrooms (1.5 pounds)

The star. They bring earthy depth and meaty texture. When properly sautéed, they develop rich umami flavor that forms the base of this Mushroom Main Dish Recipe.

Key Tip: Brown them well. Don’t rush this step.

Extra Virgin Olive Oil

Helps sauté the mushrooms evenly and adds subtle richness.

Garlic (4 cloves)

Garlic and mushrooms are best friends. Enough said.

Cream Cheese (6 ounces)

This creates the creamy backbone. It coats the mushrooms and binds everything together.

Mozzarella (½ cup)

Adds stretch and melty goodness. It softens the filling beautifully.

Parmesan (½ cup total)

Sharp, salty, and nutty. It boosts flavor in both the filling and topping.

Breadcrumbs (¾ cup total)

These create structure inside and crunch on top. That contrast? Essential.

Fresh Parsley

Adds brightness so the dish doesn’t feel too heavy.

Butter (melted)

Mixed into the topping for that golden, crispy finish.

Salt and pepper? Always season confidently.

How to Make This Savory Casserole Recipe

Let’s keep this simple and direct.

Step 1: Preheat the Oven

Set it to 350°F (175°C). Let it fully heat before baking.

Step 2: Sauté the Mushrooms

Do not rush this step. Proper sautéing builds flavor.

Step 3: Add Garlic

Stir in minced garlic. Cook for about 1 minute until fragrant.

Stir until it melts and coats the mushrooms evenly.

Remove from heat.

Step 5: Add Cheeses and Breadcrumbs

Fold in mozzarella, half the Parmesan, and half the breadcrumbs.

Now you have the filling for your ultimate Casserole With Stuffing.

Step 6: Transfer to Baking Dish
