Vegan Gluten-free Mushroom Burger

Dominic Perri for TOPS Club, Inc.

These “burgers” pair with all the garnishes for a traditional beef patty to give you a burger experience that is both vegan and satisfying. Scrape the gills—those dark brown frills—out of the caps, otherwise they’ll be overly moist.

Prep and cook time: 20 min. Servings: 2 (1 “burger” per person)

Gluten Free Vegan


  • 1 small onion, sliced into thick rings
  • 4 small portobello mushroom caps, stems and gills removed
  • cooking spray
  • 1 T. Dijon mustard
  • 2 thick tomato slices
  • pinch salt
  • 2 lettuce leaves
  • 6 slices dill pickle


  1. Prepare your grill.
  2. For security, lay onion slices flat and insert a toothpick or bamboo skewer into the center of each one to hold all of the rings together. For extra security, slide a second skewer opposite the first one.
  3. Spray the mushrooms and onions with cooking spray and lay them on the grill. Let them cook for about 4 min. per side. Move the vegetables to the cooler side of the grill and let them continue to cook until tender, about 5 min. more.
  4. Build your “burgers” by spreading the inside of the mushroom caps with a little Dijon mustard. Then top them with the grilled onions (remove the skewers first), a tomato slice (season with a pinch of salt), lettuce and pickles. Top with a second mushroom cap. Enjoy!
