If you’re craving something cozy, Stuffed Mushrooms Casserole delivers big-time flavor with minimal fuss. This dish transforms the classic party appetizer into a bubbling, golden, scoopable side that fits right in at a holiday feast—or honestly, any dinner that needs a little extra wow.

Creamy. Garlicky. Buttery. Topped with a crisp, toasty layer of panko and cheese. It’s the kind of side that quietly steals attention from the main course.

Let’s break it down in a fresh way.

Scale

8 tablespoons unsalted butter, split
1½ pounds cremini mushrooms, cut into quarters

Instructions

Start by heating your oven to 350°F so it’s ready to go.
Place a large skillet over medium-high heat and melt half of the butter. Once it’s hot and shimmering, add the mushrooms. Season with salt and pepper right away.
Cook the mushrooms for about 6 to 8 minutes, stirring occasionally. Let them brown properly—don’t rush this step. You want them deeply golden and slightly caramelized. That’s where the flavor builds.
Toss in the minced garlic and stir for about 30 seconds, just until fragrant. Turn off the heat.
Transfer the sautéed mushrooms into a 2-quart baking dish and spread them evenly across the bottom.
In a separate mixing bowl, combine the remaining butter with the cream cheese, sour cream, mozzarella, panko breadcrumbs, and Parmesan. Stir until everything blends into a thick, cheesy mixture.
Spoon this mixture over the mushrooms in small dollops, spacing them across the surface so it melts evenly as it bakes.
Slide the dish into the oven and bake for 30 to 35 minutes. When the top turns beautifully golden brown and slightly crisp, it’s ready.
Let it rest for a few minutes before serving—then dig in.
Creamy center. Crunchy top. Pure comfort.
