These community favorite Portobello Mushroom Burgers are packed with flavor, have a meaty texture, and can be cooked on the grill or stove! They’re a classic vegan or vegetarian burger recipe that’s quick to make and perfect for summer cookouts.

I used to think I didn’t like mushrooms. This recipe was my gateway to liking them. Nay, loving them.
Savory, meaty, grillable – it’s everything a burger should be.
I like to store them in the marinade until it’s BBQ time (which also makes them great for bringing to cookouts where you may be the only non-meat eater!).

“This was super good. Served on chibatta roll added peppers and onions. Sauce was great. Fussy husband loved it. He’s a burger man. It’s a do again.” —Carah

You just need a few ingredients
- Portobello Mushrooms: Grab the biggest ones you can find!
- Olive Oil: This is the base for the marinade that will infuse our mushroom burgers with flavor
- Soy Sauce: Brings salty, umami flavors and a deep brown color that helps these to look more like burgers.
- Lemon Juice: Brightens up the flavors of the burger. Fresh is best here!
- Garlic: We’re going big with 4 cloves.
- Seasonings: A quick mix of oregano, smoked paprika, salt, and pepper.

What about the gills?
Can you eat the gills of a Portobello mushroom? Yes! The texture can turn a little soft during cooking, so you can scrape them out if you prefer your mushroom caps without (we like them with gills and all).

Making these portobello burgers is a breeze
- Prep the mushrooms by brushing them in a tasty marinade.
- Cook until tender (either the grill or stove works!)
- Serve on a bun with all your favorite burger toppings.
Feeling adventurous?
Grill halloumi cheese and throw it on top of the mushroom for an ultra-filling burger!


Serve these with
- Summer Veggie Salad: Chop everything up and store in the fridge until serving time!
- Carrot Hot Dogs: Just…trust me on this one.
- Classic Black Bean Burgers for a grill full of veggie burger options!
Or for some tasty sauce ideas, you can’t go wrong by topping this burger with tzatziki or romesco!

- Cook Burgers: Heat a large non-stick skillet over medium/high. Add the mushrooms and cook for 3 minutes on each side, or until slightly softened, brushing with remaining marinade to add more flavor.

My new go-to burger. I am not vegan but family members are. This has an amazing flavor and would choose it over most any other burger. I wouldn’t change a thing.
Tasty & Quick meal !!!!
could you next time please inquire to what utensils we are meant to use while cooking, but the tast and flavor of the burger, amazing (also helpful for writing my school cooking project)
This was super good. Served on chibatta roll added peppers and onions. Sauce was great. Fussy husband loved it. He’s a burger man. It’s a do again.
I’m so happy to hear it, Carah!! Enjoy! 😀
I’ve never had a portabella burger and this was AMAZING!! The flavours were right on! Made it with grilled onion and steamed kale I needed to use, and a tomato oh and the special sauce!!! Sooooo good and so easy!! Thank you! This recipe is a keeper!
So happy to hear it, Connie! Enjoy! 😀
On a whim I bought some portabella mushrooms & came upon this recipe when trying to figure out what to do with them. My first time making a portabella burger & it was delicious! A great fast & easy meal. Thanks!
So happy to hear it, Melanie! Enjoy! 😀
We are on a very low salt diet. So I took a chance and used about 1/4 of the salt suggested in this recipe. It still turned out very delicious. I will use the same basic recipe but will try different herbs. Instead of using buns we put the mushroom burgers in large tortillas. Much healthier.
We just made these for the 31 day challenge. Discovered we were out of soy sauce! Substituted Japanese BBQ sauce from Costco. Came out great.
Happy to hear that substitute worked! Enjoy! 😀
This was the best burger I ever made! Definitely better than a Impossible burger, haha nd the saucy sauce was out of this world!!
Will definitely make again and again!
YAY! This makes me so happy to hear, Lauren! Thanks for letting us know how it went 😀
Delicious. I cooked them in air flyer.
