Portobello mushroom tacos are a great meat substitute

Mexican food is so easy to veganize! I grew up eating carne asada plates with beans, avocado, tortillas and grilled vegetables all the time. I knew I had to find a way to enjoy a that meaty, umami experience that meat provides… and this is it!
There are so many ways to substitute beef in the world of plant-based proteins. You can choose from seitan, soy curls and much more. However, my favorite meat replacement continues to be mushrooms! To be more specific, portobello and king oyster mushrooms. Portobello mushroom tacos always hit the spot if I’m ever craving something meaty!

Why are Mushrooms a Great Substitute?

Portobello mushrooms are so meaty but not TOO meaty (aka meat shreds won’t get stuck in-between your teeth). In the meat-eating world there is an obsession with “tender” meats and how to get meat to be more tender. Well portobello mushrooms are so deliciously tender and savory! Craving a carne asada-style plate? Use portobello mushrooms. Craving a shredded meat-style bowl? Use shredded king oyster mushroom.
I made these portobello mushrooms using an authentic carne asada marinade that is used in most Mexican households when we make carne asadas/barbeques! I promise this will be on of the best vegetarian portobello mushroom recipes you ever try. I hope you LOVE THEM.

Tips to make the best portobello mushroom tacos:

  • Cook them at high heat and use a heavy item to press them down while cooking so they get a nice sear. I use a molcajete or a cast iron pan.
  • I don’t recommend using another type of mushroom to substitute for portobellos for this recipe.  Find them at Trader Joe’s, Safeway, Sprouts, and most large markets.
  • You can use lime juice instead of orange juice but orange juice is highly recommended. Lime juice is great to add after it is cooked — like squeezing a fresh lime onto your carne asada taco!
  • If you want a spicer shroom I recommend using cayenne powder or chili powder from chiles de arbol. Chiles de arbol are small dried red chilis that are spicy but also so delicious.
  • If you don’t have tamari or soy sauce you can also use liquid aminos to substitute. These help give the mushrooms more of an umami flavor.
  • I highly recommend mixing all the marinade ingredients well before adding them to the zip lock bag or shaking it well after adding them in to make sure it’s evenly distributed.

This is very popular in a Mexican household and for a good reason. Pair your portobello asada with Mexican rice, beans, guacamole, grilled onions, bell peppers and some tortillas.

Burrito or burrito bowl
This is a great way to add texture and extra flavor to a plant-based burrito bowl or burrito. I like to dice the portobello slices into smaller pieces when I add to a burrito or bowl.
Carne asada quesadillas are oh so delicious! I recommend using mozzarella Follow your Heart shreds or Miyoko’s pepper jack shreds.
