These New Mexico inspired vegan Portobello Fajitas will take your taste buds to the Southwest! They are an easy weeknight meal.
These Portobello Fajitas are made in minutes in a cast iron skillet or grill pan. You could also make them on the grill. Serve them on a tortilla with avocado or guacamole, vegan sour cream, and salsa.
I vacationed in New Mexico a few years ago and ate a mushroom fajita pretty much every day. The vegan fajitas were made with Portobello mushrooms, red and green bell peppers, and onion. They were served with corn tortillas, rice, and refried beans.
Of course, I cannot leave out the famous red and green salsas that New Mexico is famous for. If you visit New Mexico and the server asks "red or green," but you want both, order "Christmas."
I reminisced about that vacation while I was making these Portobello Fajitas. I am not sure what the restaurants used to season the veggies, but I used tamari, cumin, and chili powder, and was pleased with the results.

🧾 Ingredients
- Portobello mushrooms: Adds a meaty texture and umami flavor.
- Bell peppers: I used red bell pepper and green bell pepper, but you could use whatever combination of bell peppers you like.
- Onion: Cooked onion adds a sweet, savory, pungent flavor.
- Tamari: I used low-sodium gluten-free tamari because I like to control the amount of sodium. It adds a salty umami flavor.
- Cumin and chili powder: Add warm spice flavors that are found in taco seasoning.
- Salt and pepper: To enhance the flavors and add flavor.
