Ingredients

Scale

Mushroom Filling

  • 2 tbsp unsalted butter
  • 20 button mushrooms, stems chopped, caps reserved
  • 1/2 yellow onion, finely chopped
  • 2 cloves garlic, minced
  • 1 tbsp finely chopped fresh parsley, plus more for sprinkling
  • 1 (5.2-oz) block Boursin cheese
  • 1/2 cup plain breadcrumbs, plus more for sprinkling
  • 1/2 cup grated Parmesan cheese
  • Kosher salt, to taste
  • Freshly ground black pepper, to taste
  • Extra-virgin olive oil, for drizzling

Instructions

  1. Prep and Sauté Filling: Preheat oven to 350°F (175°C). In a large skillet over medium-high heat, melt the unsalted butter. Add the chopped mushroom stems, finely chopped onion, minced garlic, and 1 tablespoon of chopped fresh parsley. Cook, stirring occasionally, until the onions are softened and the mixture is fragrant, about 5 to 7 minutes.
  2. Combine Filling Ingredients: Transfer the sautéed mixture to a medium bowl. Add the block of Boursin cheese, 1/2 cup plain breadcrumbs, and 1/2 cup grated Parmesan cheese. Stir everything together until well combined. Season the mixture with kosher salt and freshly ground black pepper according to your taste.
  3. Stuff Mushrooms: Using a small spoon, fill each reserved mushroom cap generously with the Boursin and breadcrumb mixture. Arrange the stuffed mushrooms on a baking sheet. Sprinkle additional breadcrumbs over the tops for extra crunch and drizzle with a little extra-virgin olive oil. Garnish with more chopped parsley for freshness.
  4. Bake to Perfection: Bake the stuffed mushrooms in the preheated oven for about 20 minutes, or until the tops are deeply golden and the mushrooms are cooked through. Remove from the oven and serve warm as a delightful appetizer or snack.

Notes

  • Use button mushrooms for best results as their size and shape hold the filling nicely.
  • Make sure to finely chop the mushroom stems and cook them with the other aromatics to enhance the filling’s flavor.
  • You can substitute Boursin with cream cheese mixed with herbs if unavailable.
  • For a gluten-free version, use gluten-free breadcrumbs.
  • These mushrooms can be prepared ahead and baked just before serving.
