  • 12 large white mushroom caps (12 oz) brushed clean, stems removed and discarded
  • ½ cup extra virgin olive oil
  • 8 oz lump crabmeat
  • ¼ cup mayonnaise
  • 2 tsp dried minced onion
  • 1 Tbsp prepared horseradish
  • ¼ cup plain panko breadcrumbs
  • 1 Tbsp minced Italian flat-leaf parsley
  • ¼ cup freshly grated parmesan cheese
  • 1 pinch kosher salt
  • ¼ tsp Old Bay seafood seasoning plus additional for sprinkling


  • Preheat oven to 375°F.
  • Gently use a spoon to clean out the gills and cavity of the mushrooms to make more room for stuffing.
  • Brush the mushrooms all over with olive oil and place on ungreased baking sheet.
  • In a medium bowl, stir together all of the remaining ingredients.
  • Fill the mushroom caps. Lightly sprinkle Old Bay seasoning over top.
  • Bake at 375°F for 15 minutes or until very lightly browned on top and mushroom juices are sizzly around the bottom. Serve immediately.


If large white cap mushrooms are not available, small mushrooms can be used but reduce cooking time to 10-15 minutes.
