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!).

Be sure to serve your mushroom burger with all your usual burger favorites (don’t skip my fancy sauce in the recipe card below!)

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).

Can you eat the gills of a Portobello mushroom? Yes! The texture can turn a little mushy during cooking, so you can scrape them out if you prefer your Portobello Mushroom Burgers without (but I like them with gills and all).

    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.

    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!

    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.

    1. Sarah Bond says:

      Happy to hear that substitute worked! Enjoy! 😀
