Looking for an EASY vegan dinner idea? This healthy recipe can be made in under 20 minutes! Sheet pan veggie fajitas are easy to make and incredibly delicious. Taco seasoning plus vegetables are an irresistible combination. This vegan recipe is perfect for meal prep and everyone will love making their own vegetable fajitas.
Veggie Fajitas defy being pigeon holed into a season. Am I right or am I right? I feel like they are always a good choice. Of course, I think a DIY taco bar, or fajita bar is the best possible choice for dinner (any time of year)….whether you’re having 1, 2 or 17 people over. So easy, and everyone can make theirs exactly how they want. When you use a sheet-pan to make the vegetables you make this dish that much easier on yourself. And why in the world not??
Are veggie fajitas hard to make?
Um…NO! One of the best reasons to make sheet pan veggie fajitas is because they are so easy to make. PRO TIP: You can meal prep the veggies in advance for a super quick weeknight meal.
- Prep the Veggies.
- Drizzle on olive oil, lime juice, spice mixture.
- Roast.
- Build your fajita inside a shell with your favorite toppings.
What to put in fajitas?
Traditionally, fajitas are made with bell peppers and onions. That’s it for veggies. BUT….you could really use any vegetables you want. Maybe I’d call that roasted veggie tacos….but with this spice mixture it would definitely have a fajitas vibe! I added mushrooms to the mix to give these a little umami, and still keep them vegan. What would you add to your mix?
What about shells?
Well…that depends on your preference. I like almond flour shells best, but we often use corn tortillas because those are hubbies favorite. Look for non GMO or organic corn and no processed oils in your tortillas. I like to heat the tortillas on the stove top over an open flame. You can also wrap the shells in a damp paper towel and heat/steam them in the oven. Lettuce leaves are great for wrappers as are collard greens or swiss chard. Cabbage leaves also work well.
What are good toppings for Vegetable Fajitas?
Guacamole or avocado slices are my personal favorite.
Many restaurants serve rice and beans on the side. I opt for Mexican Cauli-Rice. Another sheet pan recipe that is simple…and a great low-carb alternative to rice.
Salsa or pico de gallo is a tasty topping. This recipe for tomatillo salsa is great when tomatillos are in season. You can sub regular tomatoes using that same recipe too.
I like spice, so you will always see fresh jalapenos (or other spicy peppers) sliced in our fajita bar.
A simple slaw is another option for on top of or on the side of fajitas.
I always have a bowl of extra lime slices and fresh cilantro as additional toppings.
What do I do with leftover veggie fajitas?
Store any leftover veggies in an air-tight container in the fridge for up to 5 days. They can be reheated in the oven or in a heavy skillet on the stove. They are awesome the next day, served hot or cold….as a topping for salad or inside of tacos. The flavors will be a bit more intense…in the best possible way. I also use them as the base for a frittata…YUM.
So, as we try our best to make summer last…just a bit longer, please….and enjoy endless rounds of sheet pan veggie fajitas, I know that another season is upon us and I will enjoy these just as much in the fall and the winter and the spring. Truthfully, I’ve never met a veggie fajita I didn’t like.

You can never go wrong with great sheet pan dinners. With school back in action, we all need fast and easy weeknight meals. No takeout in our house.
Debra Klein
YAY….I love to see a commitment to home cooked meals…and this is perfect for a school night!
Amy Chung
Mexican cuisine is the one cuisine I wish we do better in Australia. I love this idea of being able to make everything in one sheet pan. That saves so much washing during those busy weeknights. Wish we could also get the different types of shells and tortillas. The range isn’t so great. But I will definitely give this healthy recipe a whirl!
Debra Klein
Love your “can do” attitude. Making what you want from scratch at home is always the best option! Enjoy.
Tina
There are 3 types of recipes that really appeal to me. One pot meals, slow cooker meals and sheet pan meals. This looks fantastic and is right up my alley. Thanks for sharing this, going to have to make this soon because this is definitely an all-year type of recipe, I agree!
Debra Klein
I’m totally with you on those categories….and you are right….they stay in the rotation all year round!
Melissa
Such a simple and delicious meal, and I love how easy it is! Throw it all together on a pan and DONE! Our family would love this, everyone likes to be involved in the meal so being able to customize their own fajitas is a bonus!
Debra Klein
My favorite kinda meal….easy clean up and everyone is happy!

What a great idea for a quick and healthy weeknight meal! So easily made on a sheet pan, and I love the idea of charring the tortilla’s over the stove top flame. Usually I just cook then in a pan, but this must be quicker!
Marisa F. Stewart
How can you possibly go wrong with fajitas?? Everyone loves them!! Frankly, I don’t think they’d even miss not having any meat in them. The peppers are loaded with flavor and they’d be so satisfying. I really love this idea for a meatless dish – plus the easy clean-up with the sheet pan.
Debra Klein
You’re so right. As long as the food is tasty and satisfying, people are happy.
Debra Klein
It IS quicker to char the tortillas over an open flame…and I also think they’re tastier…plus it saves time on clean up with one less thing to wash.
Dana
I absolutely LOVE sheet pan fajita meals! I’ve done shrimp and chicken, but never veggie. So this is awesome. I’m always looking for tasty meatless spins on dishes like this. You really don’t miss the meat with an abundance of produce like this.
Debra Klein
My thoughts exactly. Nothing to miss when the taste is all there.
Trish Bozeman
We make veggie fajitas about once a week, but I love your sheet pan version. We always just saute the veggies in the skillet, but I’ll be trying out this method for sure this week. Genius!
Debra Klein
Definitely a time saver to use the sheet pan. Less mess and a total hands off approach. We eat some version of these fajitas every week as well.

Debra Klein
Right? Nothing better than a one pan, easy clean up too.
Carole
Lacking all the fresh veggies, I used up the rest of a bag of mini sweet peppers, added an onion and some frozen veggies that needed eating — wow… that roasting spice mix is so good. Whatever you do, never neglect the lime zest and juice, plus the jalepeno’s are a must. I make my own tortillas since I cannot find good ones where I live–and tortillas are the simplest and quickest of all flat breads to make.
Debra Klein
Good job….yes, the spice mixture is what makes the veggies fajita flavor….good for you to use what you had…and it sounds like it came out great!
Donna
Yum, these veggie fajitas were so full of flavor and color! The perfect weeknight meal, and great for meatless Monday.
Debra Klein
Awesome Donna…glad you enjoyed them.
