Portobello Burgers

A simple grilled hamburger recipe using portobello mushroom caps as the bun for a healthy alternative to regular hamburgers.

These delicious mushroom burgers will brighten up any meal! Portobello, or portabella, mushrooms are the mature form of baby crimini mushrooms. They grow up to 6 inches in diameter and possess a flat cap with a dense, meaty texture. Mushrooms are one of the few natural sources of vitamin D.


  • Chop the parsley finely.
  • Tip the burger ingredients into a large mixing bowl: mince, onion, parsley, eggs, salt and pepper (optional: chilli). Mix until well combined (you can use your hands). Shape into 8 burger patties. Heat a few glugs of olive oil in a large frying pan on medium to high heat. When the oil is hot, gently lay the burger patties in the pan and fry for about 6 to 8 minutes on each side until golden. Drain on paper towels and keep warm.
  • Turn the grill on in the oven. Place the mushrooms on a baking tray. Remove the stems and drizzle with olive oil. Season with salt and pepper. Grill for about 5 minutes on each side until done.
  • To serve, divide the mushrooms between the plates and top each with a burger patty, spinach leaf, slice of tomato and a dollop of mayonnaise.
  • You can also add some grated cheese for extra flavour.
