Mushroom Sliders Recipe

  • 1 pound lean ground beef, or more to taste
  • 1 large egg
  • 1 small onion, finely chopped
  • 1 cup finely chopped mushrooms
  • 1 teaspoon ground black pepper
  • 1/2 teaspoon garlic salt
  • salt to taste
  • 6 portobello mushrooms, or more to taste
  • 1 green bell pepper, halved and seeded
  • 1 red bell pepper, halved and seeded
  • 1 yellow bell pepper, halved and seeded
  1. Preheat an outdoor grill for medium-high heat and lightly oil the grate.
  2. Mix ground beef, egg, onion, and chopped mushrooms together in a bowl, seasoning with pepper, garlic salt, and salt as you mix. Form mixture into patties about 2 inches in diameter.
  3. Grill patties on the preheated grill until browned and desired doneness is reached, 5 to 7 minutes per side. An instant-read thermometer inserted into the center should read at least 160 degrees F (70 degrees C).
  4. Grill portobello mushrooms, green bell pepper, red bell pepper, and yellow bell pepper on the grill until tender, 3 to 5 minutes per side. Use 2 mushrooms and as the 'bun' for the burgers.
