Ingredients in vegetable fajitas

Veggie fajitas keep things pretty simple. Begin with an easy 3-ingredient marinade, followed by a quick and easy mushroom, pepper, and onion vegetable blend. Finish things off with tortillas and your favorite toppings!

Marinade

• Olive Oil: Start with ¼cup of olive oil as the base of the veggie marinade.
• Lime Juice: 2 tablespoons of lime juice will add that zing that’s so crucial with fajitas!
• Taco Seasoning: Finish off the marinade with 2½ tablespoons of taco seasoning. (Want to make your own taco seasoning? See below for an easy make-it-yourself blend of spices!)

Veggies

• Mushrooms: First up, you’ll need 4 to 5 portobello mushrooms.
• Bell Peppers: For the peppers, I recommend using 3 different colors, both for presentation and for flavor!
• Onion: Finally, 1 medium red onion will add a serious amount of flavor.
• Extras: Feel free to throw whatever other veggies you want in the mix! I love adding strips of nopales (cactus leaves)!

To Serve

• Tortillas: Serve in tortillas, using either 4 large or 6 small tortillas. Feeling adventurous? Make your own flour or flavored tortillas!
• Toppings: Top with your favorite toppings, like sour cream, cilantro, salsa, avocado, and/or lime juice (these fajitas + this blender salsa = a match made in heaven).

How to make veggie fajitas

These easy vegan fajitas are all about the marinade. When you get that rolling and coat the veggies, you wind up with a seriously flavorful result. Top with your favorites, and you’re in for a mouth watering meal!

Step 1: Prep the marinade
First, preheat the oven to 450°F (230°C). Stir together all of the marinade ingredients (olive oil, lime juice, and taco seasoning).

Step 2: Prep the veggies
Next, slice the mushrooms into ¼ inch slabs. Add them to a large bowl, then toss with the marinade. Cut the peppers and onions into slices, and then add them to the bowl and toss to lightly coat with the marinade.

Step 3: Roast the vegetables
Arrange the veggies in a single layer on a parchment-lined baking sheet. Roast for 20 minutes, or until the veggies are tender and slightly charred at the edges.

Step 4: Serve
Warm the tortillas prior to serving, and then spoon the hot veggies into the tortillas. Serve with desired toppings such as cilantro, salsa, pico de gallo, avocado, and lime juice. You can also add sour cream, either regular or a vegan version.

Fajitas from Scratch

Want to make your own tortillas? Here’s an easy recipe to make your own flour tortillas that uses only 4 ingredients and tastes so good with the fajita veggies.

To make your own taco seasoning, use this blend of spices: 1 teaspoon each of chili powder, salt, smoked paprika, cumin, onion powder, garlic powder, and oregano + 1/2 teaspoon of ground black pepper.

Change up the veggies by adding your favorite Mexican vegetables, like beans or other types of peppers! Zucchini, broccoli, and eggplant also work well here.

Finally, make your own sauce to complete the meal. Some of our favorite fajitas sauces are homemade Greek yogurt (instead of sour cream) and avocado crema! Or go with a classic like our healthy guacamole or pico de gallo.
