Simple Vegan Portobello Mushroom Burgers with Sweet Onions, Avocado, Tomato and Vegan Cheese. Inexpensive, Simple To Make And Full Of Flavor. #vegan #mushroom #burgers #veganburger #simple #portobellomushroom #recipes Hi hoes, let’s go. Today’s recipe is for the Easiest Vegan Portobello Mushroom Burgers. These vegan burgers are one of the easiest ones out there because they do not require you to make a Veggie Patty – the whole, meaty texture of Portobello Mushrooms alone are enough to be used as meat or veggie patty replacement. Cool story bro.

Easiest-Vegan-Portobello-Mushroom-Burgers-3I start off with some de-stemmed Portobello Mushrooms, marinating them in a mixture of Oil, Balsamic Vinegar, Agave Nectar, Garlic, Black Pepper, Onion and Tamari. Whilst the mushrooms for your Vegan Mushroom Burgers are marinating, I cook up a batch of Red Onions nice and slow in a frying pan with a touch of Sugar, Salt and Thyme. This mixture cooks down to something very similar to Caramelized Onions, and provides so much fujking flavas to your burger. Some fancy sh*t there mate.

Simple Vegan Portobello Mushroom Burgers with Sweet Onions, Avocado, Tomato and Vegan Cheese. Inexpensive, Simple To Make And Full Of Flavor. #vegan #mushroom #burgers #veganburger #simple #portobellomushroom #recipes After your Mushrooms have sat and soaked up that lovely marinade, it’s time to bake them in the oven for 15 minutes. After 15 minutes, top with Vegan Cheese (I use BioCheese Cheddar), grill to melt, and voila, your god damn Vegan Portobello Mushroom Burgers are ready. Serve tucked in a toasted bun with Avocado, Tomato, Your Sweet Onion Mixture and a side of Sweet Potato Fries and you’re set. So if you’re keen like Tom Keen (does anyone watch The Blacklist? He’s so damn hot..), scroll down and grab the full recipe for my Vegan Portobello Mushroom Burgers. Ciao!

        This recipe is FANTASTIC. I made extra sauce and use it to marinate tofu and flavor other dishes. The mushrooms really absorbs the flavor. I marinate mine overnight and then on the grill they go! Thank you.

        I have not had a portobello mushroom burger since I was a newbie vegan - and my sweet carnivore Mum made them for me! I found 'bellos yesterday very cheap and had to buy! Thank you so much for the recipe and a new brand of vegan cheese to try! I was sure i had accidentally come to the wrong site, that looks exactly like the stuff i used to eat as a kid. Off to find the sweet potato fries, I swear I saw some in the freezer! Thank you again for sharing this recipe, I am so hungry! :0)

        The recipe says 1 1/2 balsamic vinegar. Cups? Ounces? Tablespoons? And you have the cheese listed with the marinade ingredients. Surely that doesn't get soaked to right? Thanks!

          Hey Eva, so sorry, I changed recipe plugins and I think it screwed a few things up when copying the recipes. Let me fix that for you now! :)
