Tex-Mex Vegan Fajitas are made with roasted vegetables and a homemade seasoning mix. There's no need to stand over the stove since they are cooked in the oven on a sheet pan rather than in a skillet. Serve them with tortillas, a side of beans and your favorite toppings for a complete meal.
I remember when I first started seeing fajitas served in Mexican restaurants. It was so exciting to hear the sound of the sizzling plate of food coming towards the table. And it was fun to select the ingredients and wrap them in a tortilla with your favorite toppings, like a DIY meal.
While I still order them in restaurants, making your own veggie fajitas at home in your oven is incredibly easy. Any of your favorite seasonal vegetables you normally roast will work really well in this recipe.

Why you'll love this recipe
- The seasoning is incredibly flavorful yet only requires 5 ingredients (plus salt and pepper).
- You can customize it with your favorite vegetables or whichever ones you have on hand.
- It can be served in a variety of delicious ways.
Ingredients
In addition to the traditional bell peppers and onions, I like to make fajitas with asparagus and mushrooms. You can also use zucchini, cauliflower, and eggplant.
While most supermarkets sell fajita seasoning in packets, it's really easy to make it yourself with a handful of herbs and spices, plus salt and pepper. And you probably already have most of these in your pantry:
- chili powder
- paprika
- ground cumin
- garlic powder
- oregano
While any oregano can be used, I enjoy the flavor of Mexican oregano in this recipe.
Dried Mexican Oregano
- Sourced from the finest farms in Mexico
- Fresh whole leaf provides a stronger more robust flavor than Mediterranean or Italian Oregano
- Resealable bag
For the complete list of ingredients with measurements plus recipe instructions, please see the recipe card at the bottom of this post.
Instructions
- In a large bowl, toss together the sliced vegetables, olive oil, and seasoning mix until well combined.
- Spread them out in a single layer on two sheet pans. (Line the pans with parchment paper for easier cleanup.)
- Roast until tender and lightly browned.
- Serve immediately with warmed tortillas and your favorite toppings.
Serving suggestions
Traditionally fajitas are served in small flour or corn tortillas. Then you can top them with fresh salsa, hot sauce, guacamole, and vegan cheese or sour cream.
I particularly enjoy them topped with homemade guacamole, but sliced avocados also work well in fajitas. And I usually serve some seasoned black beans on the side or you can add the beans to your fajita, too.
If you want to skip the tortillas, you can make your fajitas into lettuce wraps. Or add them to Quinoa Burrito Bowls. These roasted seasoned vegetables are also delicious as a side dish or simply served with rice and beans or on a bed of greens.
Storing and freezing
Store any leftovers covered and refrigerated for up to 5 days. Or they can be frozen for up to 3 months.
To freeze, first remove the vegetables from the baking sheets and allow them to cool completely. Then place them in a freezer-safe container with a lid and freeze. When you're ready to enjoy them, allow the container to defrost in the refrigerator overnight before reheating.
FAQ
According to Taco Literacy's History of Fajitas, fajita originates from the word "faja," meaning belt in Spanish. Traditionally fajitas were sliced skirt steak wrapped in tortillas, the skirt portion being the mid section where a belt would be on a cow, if cows wore belts. But today you'll find fajitas made with all different ingredients, including vegan fajitas with various vegetables.
According to registered dietitian nutritionist (RDN) Sharon Palmer, "Mushrooms, asparagus and cabbage supply more antioxidant compounds when cooked compared with raw. And antioxidant compounds in foods we eat may help protect against cancer and other diseases."
It's easy to make your own seasoning blend at home rather than buying a pre-mixed packet at the supermarket. Simply combine chili powder, paprika, ground cumin, garlic powder, oregano, and salt and pepper.

I make this evert other week or more, great recipe. I many 2 big roaster pans full, more than double the spices. Leftovers are chopped up a bit and mixed in with vegan Mac and cheese. That is great too.
We love these fajitas and they are easy. I do cook them for longer as it is not on a sheet pan. Thank you for a great recipe!!!!

Absolutely loved the ease in creating this recipe and of course the taste with the ingredients suggested… I did add some fresh ground pepper and I don’t ear asparagus so I did not add that. Recently been diagnosed with type two diabetes and trying to find more healthy recipes and this is a keeper.

Dinah
These fajitas taste amazing! I’ve made this recipe countless times. My husband loves it. Thanks for this wonderful recipe.

I'm so glad you are enjoying it, Dinah!
Lynn
Because my husband doesn’t eat mushrooms I usually leave them out of recipes I make, but I decided to leave the mushrooms in since I could cook them as large slices. When I made the fajitas I told my husband he could just pick out the mushrooms. He loved this recipe so much he forgot about the mushrooms! I have made this recipe three times and it’s been a winner every time!
Amy Katz
Oh my gosh, that's amazing he ate it with the mushrooms! I'm so happy everyone enjoyed it!

The seasoning is what makes this dish delicious! Also, by oven-roasting the vegetables rather than frying them, you retain the vital nutrients and taste without adding an unnecessary amount of fat. The ingredients can be varied by what you have on hand and the seasoning really makes the vegetables shine. This is wonderful rolled inside tortillas, served over rice, or eaten alone. A definite keeper!
Amy Katz
I'm so happy you enjoyed the recipe, Jayne!
Brenda

Great seasoning and the time on the recipe was perfect. I cooked at 425 because I have a hot oven.
