Ingredients

  • 1 ½ pounds white mushrooms cleaned, with stems removed
  • Mushroom stems finely diced
  • 1 cup grated Romano cheese**
  • ½ cup breadcrumbs*
  • 8 tablespoons butter
  • 1 sweet onion finely diced (about 1 cup)
  • 2 garlic cloves minced
  • Kosher salt to taste
  • Freshly ground pepper to taste

Instructions

  • Preheat the oven to 400°F (200°C).
  • In a large skillet, melt the butter over medium heat. Add the diced mushroom stems and onions, sautéing until the onions become translucent, about 10 minutes.
  • Stir in the minced garlic, cooking briefly until fragrant. Remove the skillet from heat.
  • Incorporate the breadcrumbs and grated Romano cheese into the skillet, stirring until evenly combined. Season with salt and pepper to taste, being cautious with the salt as the cheese adds a natural saltiness.
  • Using a teaspoon, fill each mushroom cap with the mixture, gently mounding extra filling on top to form a small peak.
  • Arrange the stuffed mushrooms on a baking sheet lined with parchment paper or foil.
  • Bake in the preheated oven for 15-20 minutes, or until the tops are golden and crispy.

Notes

  • If opting for panko breadcrumbs, use twice the amount specified.
  • Parmesan cheese can replace Romano for a milder taste, though it will slightly reduce the sharpness.
  • To prepare in advance, refrigerate the filled mushrooms, loosely covered, to allow some moisture to escape. Chilling them beforehand results in a delightful texture post-baking.
