These garlic butter miso mushrooms are the ultimate burger topping. They’re loaded with flavor, simple to make, and will take your cookouts to the next level. 


  • 1/3 cup dairy-free butter, melted
  • 8 oz shiitake mushrooms
  • 4 cloves garlic, finely diced
  • 1 tablespoon soy sauce (or tamari for gluten-free)
  • 1 tablespoon miso paste
  • 1/2 tablespoon rice vinegar
  • Sprinkle black pepper


  1. In a medium bowl add all of the ingredients except the mushrooms and whisk them together until smooth.
  2. Add in the mushrooms and gently mix them into the marinade. Set aside for 10-15 minutes while the grill preheats to 500 degrees.
  3. Transfer your mushrooms to a cast iron pan, put them on the grill, and let them cook until golden and crispy. This will take around 15-20 minutes. As your mushrooms cook you can also prepare your burger.
  4. Assemble your burger with the mushrooms and other toppings as desired and enjoy! 


  • For our burger, we like to use vegan brioche buns, lettuce, vegan cheese, garlic miso mushrooms, and vegan big mac sauce.
  • These can be prepared on the stove as well.
