  • 15 (about 1½ lbs.) large button mushrooms
  • ½ lb. lean ground beef
  • ½ cup finely chopped mushroom stems
  • 1 cup cooked brown or white rice
  • 1 cup shredded mozzarella cheese, divided

cooking methods

  • Bake
  • Stovetop


Preheat oven to 350°. Clean mushrooms and remove stems. With a spoon, gently scrape out the gills (the dark brown striated flesh on the underside of the mushroom). Place in a 9 x 13 baking dish. Set aside.

Combine beef, chopped mushroom stems and Onion Onion™ Seasoning in a large skillet over medium-high heat. Cook and crumble until beef is no longer pink. Drain. Remove from heat and stir in rice and ½ cup cheese. Fill mushroom caps. Sprinkle with remaining cheese and bake 25 minutes.
