Portobello mushrooms turn into meaty, savory vegan fajitas with one sheet pan and 30 minutes. This plant based weeknight dinner is a winner!

Homemade fajita seasoning

These 30 minute vegan fajitas are flavor-packed. All of that flavor comes from our homemade fajita spice blend.

It's warming, a bit sweet, with just the right amount of heat. Plus, if you're looking to make this dinner even faster, you can make the spice blend ahead of time. Just whip it up and store it in an airtight container.

You could even make a big batch of our fajita seasoning. Then, you'll have some on hand to flavor any kind of vegetable or protein.

If you've got meat lovers in the family, the fajita spice could flavor chicken, beef or pork. Or, sprinkle it over all kinds of vegetables.

Then roast them up or make a fajita spiced stir fry for dinner. This seasoning would also be delicious on crumbled tofu or beans for a plant-based high-protein dinner.

Ingredients

  1. Coconut sugar. This natural sweetener adds a bit of sweetness to our fajitas and balances the spices.
  2. Chili powder. Chili powder packs just a hint of heat. It's fairly mild, so we add a whole tablespoon and a half to our seasoning blend.
  3. Cumin. Cumin is a foundational Mexican spice. It's warming and nutty.
  4. Garlic powder. We rely on garlic powder for most dry spice blends. A little goes a long way though! It packs a lot of garlicky flavor, and unlike fresh garlic, it lasts a long time in your pantry.
  5. Paprika. One of my personal favorite spices, paprika is the secret to smoky flavor without a grill. Or even going outside. You can pack smokiness into your meals all year long with a stocked supply of smoked paprika.
  6. Dried oregano. If you can, go for Mexican oregano for these fajitas. It's less finely ground, which adds texture to the spice blend. It's also more floral tasting.
  7. Cayenne. This is where most the heat in our fajitas come from. Use only as much as you like. If you're very sensitive to spice, you could also leave the cayenne out.

After mixing all of these fragrant Mexican spices together, you've got a flavor-packed homemade spice blend to use whenever you want! Now, just sprinkle it over your vegetables and you're 20 minutes from these vegan mushroom fajitas.

Fajita Ingredients

While mushrooms steal the show of this satisfying plant-based dinner, we had to toss some more vegetables in for color and, of course, nutrition. We like a fajita that's hard to close, there's so much delicious vegetable filling packed inside.

Potatoes add heartiness and make this sheet pan dinner super filling. We used Yukon gold potatoes, but purple would make a beautiful accent. Sweet potatoes would work, too!

The key is to cut the taters into thin wedges of the same size. That way, they'll cook at the same time as the mushrooms and other veggies.

Purple onion complements our portobellos in these fajitas. They provide a foundational sweet flavor. If you ask me, no meal is complete without melty onions!

Yellow and green peppers bring festive color to these fajitas. And what's better than peppers and onions? Of course, you can use whichever pepper color you like best. Red or orange would add even more brightness.

When you're making these sheet pan mushroom fajitas, slice everything in similar sizes. Also, don't be afraid to break out a second sheet pan.

Whenever you roast veggies, you want to give them plenty of space. If they're touching or too close together, you'll end up steaming the veggies rather than roasting them.

Remember: space makes things crispy!

Toppings

Now comes the fun part. It's time to top and assemble your vegan portobello fajitas! Sliced avocado (or guacamole) is a no-brainer. Fresh cilantro and lime slices brighten everything up.

Lastly, if you have a few extra minutes, you could mix up a batch of quick-pickled onions.

Finally, before digging into these mushroom fajitas, warm your tortillas. You can pop them into the oven directly on the racks. They'll warm up in just 2 minutes. Alternatively, heat them directly over the flame on a gas stove until slightly charred and pliable.

More topping ideas include sour cream, cheese, hot sauce, salsa, etc.

Description

Portobello mushrooms turn into meaty, savory vegan fajitas with one sheet pan and 30 minutes. 


Ingredients

Scale

Homemade fajita seasoning:

  • 1 tbsp coconut sugar 
  • 1½ tbsp chili powder 
  • 1 tbsp cumin 
  • 1½ tsp garlic powder
  • 1¼ tsp paprika 
  • 1 tsp dried oregano
  • ¼-½ teaspoon cayenne, depending on how spicy you want it
  • 1¾ -2 teaspoon kosher salt 
  • ½ tsp black pepper

Fajitas:

  • 2 medium or 3 small portobello mushroom caps, sliced
  • 2 cups potato, thinly sliced
  • 1 large purple onion, thinly sliced
  • 1 large red pepper, sliced
  • 1 large green pepper, sliced
  • ½ cup olive oil
  • 1½ tbsp lime juice
  • ⅓ cup freshly chopped cilantro, plus more for topping
  • 4 tortillas
  • Pickled red onion, for topping
  • 1 avocado, sliced thinly, for topping

Instructions

  1. Preheat oven to 400˚ F. Line a baking sheet with parchment paper. In a small bowl, combine the coconut sugar, chili powder, cumin, garlic powder, paprika, oregano, cayenne, salt and pepper. 
  2. Add the mushrooms to one bowl and the potato, onion and peppers to a separate bowl. Whisk the olive oil and lime juice together. Add 2 tablespoon of the spice blend, 2 tablespoon of the oil mixture, and 1 tablespoon chopped cilantro to the mushrooms and toss very gently to avoid breaking up the mushrooms. Add the rest of the spice blend, chopped cilantro, and olive oil mixture to the rest of the vegetables and toss well to coat evenly.  
  3. Spread the veggies out on the prepared baking sheet and roast for 25 minutes, stirring halfway. You may need two baking sheets if the veggies don’t fit on one in a single layer. 
  4. Before serving, warm the tortillas directly on the oven racks for 2 minutes.
  5. Serve the fajita veggies on warmed tortillas topped with pickled onions, avocado, and fresh cilantro. 

Notes

You could also add tofu to the sheet pan for protein or serve with black or pinto beans.  For the meat lover in your family, try adding thinly sliced beef or sliced chicken.

    I love using portobellos in recipes in place of meat and that blend with coconut sugar sounds absolutely amazing. I have never used coconut sugar in my fajita spice - and I totally have to try this.

    One huge thing I really like about these fajitas is the color. Colors to be more precise. I don't know why but when I look at the photos, I get a feeling I look at some sort of art, and it feels amazing. Can't wait to recreate these at home now!

    I always buy my own Fajita seasoning because I did not know it is very easy to make. The ingredients are always present in my pantry, so next time, I will make my own.
