Ingredients
  

  • For the Stuffed Mushrooms:
  • 18–20 large white or cremini mushrooms
  • 1 tablespoon olive oil (for brushing)
  • 1 tablespoon butter (for sautéing mushroom stems)
  • 1 clove garlic, minced
  • 1/2 cup finely chopped onion
  • 1/2 cup breadcrumbs (preferably Panko for crunch)
  • 1/4 cup grated Parmesan cheese
  • 1/4 cup cream cheese, softened
  • 1/4 cup mayonnaise
  • 1 teaspoon Dijon mustard
  • 1 tablespoon fresh parsley, finely chopped
  • 1/2 teaspoon Old Bay seasoning (optional, but recommended)
  • 1 cup lump crab meat (fresh or canned, drained)
  • Salt and black pepper, to taste
  • For the Garlic Butter Topping:
  • 3 tablespoons unsalted butter, melted
  • 2 cloves garlic, minced
  • 1 tablespoon lemon juice
  • 2 tablespoons breadcrumbs
  • 1 tablespoon grated Parmesan cheese
  • 1 teaspoon parsley, finely chopped

Instructions
 

  • Step 1: Prepare the Mushrooms : Preheat oven to 375°F (190°C). Clean the mushrooms gently with a damp paper towel. Remove the stems carefully and set them aside (for stuffing mixture). Lightly brush mushroom caps with olive oil and place them hollow-side up on a baking sheet lined with parchment paper.
  • Step 2: Make the Filling : Finely chop the mushroom stems. In a skillet, melt butter over medium heat. Add onion and chopped mushroom stems; sauté for 3–4 minutes until soft. Add minced garlic and cook for 30 seconds until fragrant. Transfer the mixture to a bowl and let it cool slightly. Stir in breadcrumbs, Parmesan, cream cheese, mayonnaise, mustard, parsley, Old Bay seasoning, salt, and pepper. Fold in crab meat gently to avoid breaking it up too much.
  • Step 3: Stuff the Mushrooms : Spoon the crab mixture into each mushroom cap, mounding it slightly. Arrange them evenly on the baking sheet.
  • Step 4: Prepare the Garlic Butter Topping : In a small bowl, combine melted butter, garlic, lemon juice, breadcrumbs, Parmesan, and parsley. Sprinkle a little of this mixture over each stuffed mushroom.
  • Step 5: Bake ; Bake for 20–25 minutes, until the tops are golden and bubbly. Remove from the oven and let cool for 5 minutes before serving.
