Ingredients

  • 30 ounce package slow cooked beef roast with au jus
  • 6 portobello mushrooms
  • 1 medium onion sliced thin
  • 6 slices pepper jack cheese
  • Fresh parsley chopped, for garnish

Instructions

  • Preheat oven to 350 degrees. Line a sheet pan with parchment paper. 
  • Remove stems and brown gills from the undersides of mushroom caps using a spoon, and discard. Place mushrooms on prepared baking sheet and brush the tops of the mushrooms with olive oil and set aside.
  • Place sliced onion in a large skillet along with beef and au jus. Cook covered over medium heat for 7-8 minutes until beef is heated through and onions are just tender. 
  • Turn over mushrooms and stuff each one with equal amounts of beef mixture and top with one slice of pepper jack cheese. Reserve au jus for topping once cooked.
  • Bake for 25 minutes. Remove and top with au jus and fresh chopped parsley.
