Ingredients

  • 2 medium (140g total) Portobello mushroom caps, gills scraped
  • 2 tsp Olive oil
  • 4 oz (113g) Ground beef (80/20)
  • 1 (28g) Cheddar slice
  • 1 tbsp Butter
  • 1 clove Garlic, minced
  • 1 tsp Fresh parsley, chopped
  • to taste Salt and black pepper

Method

  1. Brush portobello caps with olive oil and season with salt and pepper.
  2. Grill or pan-sear caps stem-side down over medium-high heat 3-4 minutes per side until tender and lightly charred. Set aside on paper towels — mushrooms release liquid.
  3. Form the beef into a patty matching the cap diameter; season generously and sear 3 minutes per side for medium.
  4. Melt butter with minced garlic in a small skillet over low heat for 1 minute; stir in parsley.
  5. Top the patty with cheddar in the last 30 seconds and cover briefly to melt.
  6. Brush garlic butter on the inside of each cap, sandwich the patty between them, and serve immediately.
