Are Portobello Mushroom Burgers Vegan?
They certainly can be! This portobello mushroom burger recipe uses portobello mushroom caps, balsamic vinegar, oilve oil and some spices – all are vegan friendly.
Then the rest of the ingredients you need to make a burger are really up to you.
- lettuce
- onion
- tomato
- vegan mayo – Primal Kitchen and Chosen Foods make vegan mayo, or I highly recommend making this chipotle aioli.
- buns – buy certified vegan ones if you’d like
- cheese – there are so many plant based cheese slices options out there now. Miyokos brand, Follow Your Heart and Field Roast all make vegan cheese slices.
Mushroom Marinade
The key to making this mushroom burger taste amazing is the balsamic marinade.
You just need:
- balsamic vinegar
- coconut aminos (or tamari or soy sauce)
- olive oil
- onion, garlic, & paprika powder
- pepper
Let the mushroom caps sit in the marinade for about 20 minutes, flipping halfway through and making sure to brush into the mushroom gills.
What does a Mushroom Burger Taste Like?
Mushroom burgers won’t taste like a hamburger patty, but they are hearty and meaty in their own way. They’re a great way to eat more plants and an easy-to-make vegetarian burger option.
When you factor in all of the traditional burger toppings, you may not even miss the meat.
You can grill the portobello mushroom caps, or use a cast iron skillet to cook over medium-high heat.
Serve with steak fries (and a beer!) for an “authentic” burger experience.

Portobello Mushroom Burger
Ingredients
Mushroom Burgers
- 4 large organic portobello mushrooms, stems trimmed
- 2 tablespoons balsamic vinegar
- 2 tablespoons coconut aminos, or tamari, or soy sauce
- ½ teaspoon onion powder
- ½ teaspoon garlic powder
- ½ teaspoon paprika
- ½ teaspoon black pepper
- ¼ teaspoon fine sea salt
For Serving
- 4 burger buns
- 4 slices steak tomatoes
- 4 slices red onion
- lettuce or greens of choice
- vegan mayo, or other condiments
Instructions
- Place mushrooms, tops up, in a shallow dish.
- In a small bowl whisk together balsamic vinegar, olive oil, spices, salt and pepper. Pour over mushrooms and use a pastry brush to make sure mushroom caps have been well seasoned. Flip over and brush marinade into mushroom gills. Let sit for 10 minutes before flipping over and marinating for another 10 minutes.
- Meanwhile prepare the rest of the ingredients for serving.
- After the mushrooms have marinated, add to a hot cast iron grill pan (or heated grill) and cook for about 5 minutes per side. If using a grill pan or outside, feel free to brush the mushrooms with leftover marinade. (If doing this in a traditional cast iron skillet, the mushrooms may get a little too soggy.)
- Add lettuce to buns, then mushroom, cheese slices if using, tomato slices, onion and top bun with mayo if you’d like. Serve immediately with favorite sides like steak fries, sweet potato fries, or I like this brussels quinoa salad.
