I started experimenting with this recipe a few weeks ago and couldn’t be happier with how it came out. The best part is it only contains a handful of simple ingredients and is ready in less than 30 minutes. I recommend preparing this recipe on a grill since it adds a pleasant smokey and chard element to the mushrooms, but preparing them on a stovetop indoors works well too. 

ingredients for Garlic Butter Miso Mushrooms (Ultimate Burger Topping)

Here’s What You Need for These Garlic Butter Miso Mushrooms:

  • Vegan Butter: To add some richness to our marinade, melted dairy-free butter is the key. If you don’t have or don’t want to use butter, you can also use a neutral high-heat oil like avocado. We like to use Country Crock Plant Butter.
  • Mushrooms: I recommend using shiitake mushrooms for this recipe, but oyster mushrooms, button/cremini mushrooms, or any other type of mushroom would also work well. 
  • Rice Vinegar: The addition of rice vinegar adds an acidic element to round out the rest of the flavors in the recipe. Rice vinegar also has a subtle sweetness that helps give depth to the mushrooms. If you don’t have or don’t have access to rice vinegar, you can also use white or apple cider vinegar. 
  • Soy Sauce: This will add some saltiness and umami to our mushrooms. If you want to make this recipe gluten-free, you can swap soy sauce for tamari.
  • Miso Paste: If you’re unfamiliar with miso, it’s a light, salty, and savory paste made from soybeans. White miso paste works best for this recipe. Here’s one we recommend!
  • Garlic: Lots of fresh garlic is the key to this recipe. We recommend four cloves, but feel free to add more if that’s your thing. Dicing the cloves as finely as possible will help bring out all of the delicious garlicky flavors. 
  • Black Pepper: A sprinkle of black pepper is the final touch for our mushrooms.

Additional Equipment:

  • Cast iron pan – You can also use a saucepan if you’re not cooking these on a grill. 
  • Grill (optional) – This recipe was tested on a gas grill and the flavor was incredible.
  • Stovetop (optional) – If you don’t have, or are unable to use a grill, this works well, too.
  • Small bowl/medium bowl
  • Large spoon

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.  
  • Prep Time: 20 minutes
  • Cook Time: 20 minutes

  1. This recipe is so yummy. I usually use mushrooms for omelet and rice mainly, but I will try for burgers too.
