Makes about 16 stuffed mushrooms

  • 8 oz Cremini Mushrooms
  • 1 bag Schoolyard Snacks Sour Cream and Onion Puffs
  • 6 oz Cream Cheese, softened
  • 1/3 cup Gruyere, shredded
  • 2 tbsp Butter
  • 2 tbsp Chopped White Onion
  • 1/2 tsp Garlic Powder
  • 2 tbsp Fresh Chopped Parsley
  • 1/2 tsp Salt


  1. Preheat oven to 375F and wipe any dirt from the mushrooms with a damp cloth. Remove the stems finely chop to use in the filling; set the caps aside. 
  2. In a skillet melt the butter over medium heat and saute the onion until translucent. Add the chopped mushroom stems and continue to cook until soft; about five minutes. Remove from heat. 
  3. Pulse the Sour Cream and Onion Puffs in a food processor to large crumbs. In a large bowl mix the softened cream cheese, crushed puffs, onion mixture, shredded gruyere, onion powder, chopped parsley, and salt. 
  4. Fill the clean mushroom caps with the filling mixture and arrange in a baking dish. Bake uncovered for 15-20 minutes or until the mushrooms are tender. If the tops begin to overbrown, lightly cover with foil and continue baking. Serve hot.
