Equipment

  • Baking Sheet
  • Large Skillet
  • Pastry Brush

Ingredients
  

  • 4 large portobello mushrooms  stems removed, gills scraped
  • 1 lb thinly sliced beef (ribeye or sirloin)
  • 1 small onion thinly sliced
  • 1 green bell pepper thinly sliced
  • 1 cup shredded provolone or mozzarella cheese
  • 2 tbsp olive oil
  • Salt and pepper to taste
  • 1 tsp garlic powder (optional)

Instructions
 

  • Preheat the oven to 400°F (200°C). Place the cleaned mushrooms on a baking sheet, brush them with olive oil, and season with salt. Bake for 5-7 minutes to soften slightly. Remove and set aside.
  • Heat the remaining olive oil in a large skillet over medium heat. Add the onions and bell peppers, sautéing until softened and slightly caramelized, about 5 minutes. Move the veggies to one side of the skillet.
  • Add the sliced beef to the empty side of the skillet. Season with salt, pepper, and optional garlic powder. Cook until the beef is browned.
  • Evenly spoon the beef and veggie mixture into each mushroom cap. Top each with shredded cheese.
  • Bake for 8-10 minutes until the cheese is melted and bubbly.
  • Let cool slightly and serve warm.
