Ingredients You’ll Need

Each ingredient in this Boursin-Stuffed Mushrooms Recipe plays an important role, from the buttery sautéed stems to the tangy cheese and crunchy breadcrumbs. I always recommend using fresh mushrooms and real Boursin cheese for the best flavor and texture.

• Unsalted butter: Helps sauté the mushroom stems and vegetables without adding extra salt; gives a rich base flavor.
• Button mushrooms: A classic choice—small, firm, and perfect for stuffing.
• Yellow onion: Adds sweetness and depth when cooked down with the mushroom stems.
• Garlic: Gives that irresistible aroma and flavor that pairs beautifully with the cheesy filling.
• Fresh parsley: Brings a bright, fresh note inside the filling and as a sprinkle on top.
• Boursin cheese: The star of the show—creamy, herby, and full of flavor.
• Plain breadcrumbs: Add texture to the filling and a crispy topping when sprinkled and baked.
• Grated Parmesan: Adds nuttiness and umami, balancing the creaminess of the Boursin.
• Kosher salt and freshly ground black pepper: Essential for seasoning every layer of flavor.
• Extra-virgin olive oil: A light drizzle before baking helps crisp up the breadcrumb topping wonderfully.

Variations

I love to customize this Boursin-Stuffed Mushrooms Recipe depending on what I’m in the mood for or what’s in the fridge. Feel free to play with herbs and add-ins to make it your own.

• Adding cooked bacon or pancetta: My family goes crazy when I toss in some crispy bacon bits into the filling—adds a smoky crunch that pairs perfectly with the creamy cheese.
• Using different mushrooms: I’ve tried cremini or even baby portobellos for a meatier bite, and they work beautifully.
• Make it vegan: Swap out the Boursin for a plant-based herbed cheese and use vegan butter and breadcrumbs.
• Adding fresh herbs: If you have thyme or rosemary on hand, chop some finely and add for extra fragrance.

How to Make Boursin-Stuffed Mushrooms Recipe

Step 1: Prepare and Sauté the Filling

Start by preheating your oven to 350°F. While it warms up, take your mushroom stems and chop them finely—this is key for a juicy filling without wasting any of the mushrooms. Heat unsalted butter in a skillet over medium-high heat and cook the chopped stems, diced yellow onion, minced garlic, and parsley. Stir occasionally until the onions soften and everything smells heavenly, which usually takes about 5 to 7 minutes. This step builds a flavorful base that you’ll mix with the Boursin cheese.

Step 2: Mix the Filling Ingredients

In a medium bowl, combine the sautéed mixture with softened Boursin cheese, plain breadcrumbs, and grated Parmesan. I usually add salt and freshly ground black pepper here to taste. The breadcrumbs help hold the filling together while adding a little texture, and the Parmesan boosts savoriness. Give it a gentle mix—you want everything evenly incorporated without mashing it too much.

Step 3: Stuff the Mushroom Caps

Grab your reserved mushroom caps and carefully fill each one with a generous spoonful of the Boursin mixture. Don’t be shy—make sure each cap is nicely filled so you get a perfect bite. Sprinkle a bit more breadcrumbs on top for some crunch after baking, then drizzle lightly with extra-virgin olive oil. Finally, add a sprinkle of fresh parsley for a pretty, fresh finish.

Step 4: Bake Until Golden and Delicious

Place your stuffed mushrooms on a baking sheet or in an oven-safe dish and bake at 350°F for about 20 minutes. You’re aiming for the filling to be bubbly and golden brown on top. One thing I’ve learned is to watch the breadcrumbs closely – if they start browning too fast, you can tent them loosely with foil. Once they’re cooked through and beautifully golden, take them out and let them cool for a few minutes before serving.

How to Serve Boursin-Stuffed Mushrooms Recipe

Garnishes

I love topping these mushrooms with a bit of fresh parsley or chives for color and brightness right before serving. A tiny drizzle of balsamic glaze can be a surprising but delightful addition if you want to jazz things up. Sometimes, a squeeze of lemon juice adds a nice hint of acidity that balances the rich cheese.

Side Dishes

These stuffed mushrooms go wonderfully with simple green salads, crusty bread, or even alongside hearty mains like roasted chicken or steak. I’ve also paired them with a light pasta dish and a glass of white wine for easy yet elegant weeknight dinners.

Creative Ways to Present

For special occasions, I like arranging the mushrooms on a large serving platter lined with fresh herbs or edible flowers to make a stunning visual. You could also serve them on individual appetizer spoons or mini plates at a cocktail party—makes the experience feel all the more luxe and inviting.

Make Ahead and Storage

Storing Leftovers

Once cooled, place any leftover stuffed mushrooms in an airtight container and refrigerate; they stay delicious for about 3 days. I find the texture and flavor hold up nicely, especially if you reheat them gently to keep the cheese creamy.

Freezing

While I don’t usually freeze this recipe because fresh mushrooms are best, you can freeze them if needed. Pop them on a baking sheet to freeze individually first, then transfer to a freezer-safe bag. Thaw overnight in the fridge and reheat gently. The texture might be a bit softer but still tasty.

Reheating

To reheat, I preheat the oven to 325°F and warm the mushrooms for 10 to 15 minutes until heated through. This keeps the topping crisp while melting the filling back to its creamy glory—microwaves tend to make them soggy.
