  • 2 Vidalia onions
  • 1/2 tbsp olive oil unrefined
  • 1/2 tbsp unrefined salt
  • 1/2 tbsp balsamic vinegar

Lions Mane Mushroom

  • 1 lb Lions mane mushroom
  • 1/2 tbsp olive oil unrefined
  • 1 tsp black garlic salt or unrefined salt
  • 1/2 tbsp dried thyme
  • 1/2 tbsp black pepper
  • 2 burger buns
  • 2 slices vegan smoked gouda


Caramelized Onions

  • Slice onions into slices:
    Cut onion in half on its pole. Cut off the bottom and peel off the outer layer.
    Cut off the top of each half, and cut thin slices.

Lions Mane Mushroom

  • Heat cast iron over medium heat. Add olive oil and onion slices. Add salt.
    Stir every 2-3 minutes. Add a splash of water if onion starts to stick to the pan.
    Cook for about 25-35 minutes. Right before removing from the pan, add the balsamic vinegar and quickly stir.
  • Clean the skillet, and re-heat to medium heat. Slice the mushroom into 1/2" steaks.
    Add steaks to the dry pan. Cook until lightly brown, for about 5 minutes on each side.
  • Add olive oil and coat each steak. Add salt, pepper, and thyme.
    Cook for another 3-4 minutes on each side until a beautiful golden-brown flavor develops.
    Remove from pan.

Assemble Burger

  • Toast burger bun using residual heat from cooking the mushrooms.
  • Add caramelized onions to bottom bun.
    Place cooked mushroom steaks on top.
    Add a piece of vegan smoked gouda and top bun.
  • Enjoy it!!!
