Ingredients

Scale

Mushrooms

  • 1 1/2 lbs. baby Bella mushrooms
  • cooking spray (for pan)

Stuffing

  • 2 tablespoons butter (unsalted)
  • 2 tablespoons green onions (diced)
  • 4 cloves garlic (minced)
  • 1/4 cup breadcrumbs (plain)
  • 1/4 teaspoon Kosher salt
  • freshly ground black pepper (to taste)
  • 1/3 cup freshly grated Parmesan (plus more for topping)
  • 4 oz. cream cheese (softened to room temperature)
  • 2 tablespoons mayo
  • 1 teaspoon Italian seasoning dried herbs
  • 2 tablespoons freshly chopped parsley

Instructions

  1. Preheat Oven: Preheat your oven to 400°F (204°C) to get ready for baking the mushrooms.
  2. Prepare Baking Sheet: Line a baking sheet with parchment paper and lightly spray it with cooking oil to prevent sticking. Set aside.
  3. Prepare Mushrooms: Clean the mushrooms thoroughly, remove the stems, and roughly chop the stems. Place the mushroom caps with the hollow side up onto the prepared baking sheet.
  4. Make Stuffing Mixture: In a bowl, combine the chopped mushroom stems with butter, green onions, minced garlic, breadcrumbs, Kosher salt, black pepper, freshly grated Parmesan, softened cream cheese, mayo, Italian seasoning, and freshly chopped parsley. Stir well until fully combined.
  5. Stuff Mushrooms: Spoon the prepared stuffing mixture into each mushroom cap, filling them generously.
  6. Bake: Place the baking sheet in the preheated oven and bake for about 15-20 minutes or until the stuffing is golden-brown and the mushrooms are cooked through.

Notes

  • For best results, use fresh baby Bella mushrooms and avoid washing them under running water; instead, wipe with a damp cloth.
  • The stuffing can be prepared a few hours ahead and kept refrigerated before baking.
  • To make this dish gluten-free, substitute plain breadcrumbs with gluten-free breadcrumbs.
  • Feel free to add cooked sausage or crab meat into the stuffing to make it heartier.
  • Use freshly grated Parmesan for a better flavor compared to pre-grated varieties.
