Sheet Pan Fajita Veggies & Ingredients

One of the best things about making veggie fajitas is the versatility. Just like some people use steak, chicken, or shrimp you can add and swap out your favorite vegetables. There’s no wrong way!

For this recipe I used:

  • Mushrooms
  • Red and green bell peppers
  • Red onion
  • Cauliflower

Some other options are broccoli, squash, and asparagus.

Once you decide on your fajita vegetables all you need is your seasoning. I used my homemade fajita seasoning. It’s super easy to make and is a blend of chili powder, paprika, garlic powder, onion powder, cumin powder, oregano, and a little cayenne for heat.

How To Make Vegan Sheet Pan Fajitas

This recipe could not be any easier or healthier.

  1. Preheat your oven to 425˚F and line a large baking sheet or 2 smaller baking sheets with parchment paper.
  2. Spread the prepared vegetables in a single layer on the baking sheet, sprinkle with the fajita seasoning, and gently toss all of the vegetables until they are evenly covered with the seasoning.
  3. Place the vegetables in the oven and bake for 25 minutes. While the vegetables are roasting begin preparing the tortillas and any toppings you desire. My favorites are a little guacamole and my tofu sour cream.
  4. To serve, spoon a generous amount of veggies onto the tortillas and top with guac and sour cream then drizzle with a little fresh lime juice.

Enjoy!

Serving Suggestions

Burrito Bowls: Serve the veggies over rice and make some delicious burrito bowls.

Sauces: Top with some delicious sauces like hot sauce, salsa, or vegan chipotle aioli to add extra layers of flavor.

Sides: black beans or fat-free refried beans add extra protein, and fiber, and really complete the meal.

Tortillas: Corn tortillas are my favorite but whole wheat flour tortillas are excellent as well.

Make a batch of my healthy crunchy taco shells and make some killer veggie tacos.

Storing and Freezing

Refrigerator: Place leftovers in an airtight container and refrigerate for up to one week.

Freeze: Let the vegetables completely cool. Place them in a freezer-safe container with a lid and freeze for up to 3 months. When you’re ready to enjoy, place the container in the refrigerator overnight allowing the veggies to thaw and reheat.

    Made the veggies and served with jackfruit kabobs. Made enough for tomorrow’s fajitas to have with a green salad. Two very easy meals and so good. Thanks Shane , you never fail with the winners.

    Delicious and easy. Followed recipe exactly except I used cashew sour cream instead of tofu sour cream and husband loved it too. Will have leftovers tomorrow.
    Thank you.

    Can I use frozen veggies for this? If so, how long would I roast them? Thanks!

    These are amazing. My husband hates cauliflower so I only used half a head. The homemade seasoning was excellent. Will definitely make these often. Great 4th of July dinner! Thank you, Shane.
