Oven-Roasted Vegetable Fajitas | Vegan Recipe - Elavegan (1)

Hey, I hope you are as excited as I am about these delicious vegetarian fajitas with oven-roasted vegetables! As you know, I love Mexican food (well, rather Tex-Mex). Most of my Mexican inspired recipes are not “traditional” Mexican recipes though. Why? Because I always add my own twist which sometimes is not Mexican AT ALL, haha.

However, I want to share vegan recipes with you, which I enjoy most, and to me, it’s not important if they are “real”, “traditional” or whatever. They are yummy and that’s all that matters, right?

When my boyfriend came home with these beautiful peppers, I knew what I am going to make! Yummy veggie fajitas!

What are Fajitas?

I think it’s best if I quote Wikipedia here:

A fajita in Tex-Mex cuisine is any grilled meat that is served as a taco on a flour or corn tortilla. The term originally referred to skirt steak, the cut of beef first used in the dish. Popular meats today also include chicken and other cuts of beef, as well as vegetables instead of meat.

Of course, I didn’t use grilled meat since I am an ethical vegan. Some years ago I rescued two dairy-cows which now live on a farm of my friend and last year I rescued my pet chicken “Erna”. I prefer vegan fajitas with oven-roasted vegetables!

Why Oven Roasted Vegetable Fajitas?

  • Roasting the vegetables brings out so much flavor. I just LOVE caramelized veggies.
  • It’s easier to roast the veggies in the oven because they don’t require babysitting!
  • Crispy edges! Do I have to say more?!

How To Make Vegetable Fajitas?

You are only a few steps away from enjoying flavorful sheet pan fajitas. These bad boys are seriously so easy to make. All you need is:

  1. Vegetables (peppers, cauliflower, onion) or use veggies of choice
  2. Fajita seasoning
  3. Black beans or use kidney beans
  4. Guacamole
  5. Tortillas
  6. A little oil
  7. Vegan cheese sauce (totally optional and not “traditional” at all, haha)

All ingredients, measurements, and nutrition facts (calories, etc.) can be found in theprintable recipe card below.

Instructions:

STEP 1: Start by chopping the veggies and spread them on a baking sheet. Drizzle with some oil, toss with fajita seasoning and roast in the oven until nicely caramelized and tender.

STEP 2: It’s up to you if you prefer heating up the beans but I love to fry them for a few minutes in a skillet with a little balsamic vinegar, salt, and onion powder.

STEP 3: Make your own guacamole or use store-bought. I have a recipe for Oven Baked Potato Wedges with homemade Guacamole. Check it out if you want.

STEP 4: Finally, assemble your vegetable fajitas. Check the easy step-by-step photos below.

Healthy Veggies

These vegetarian fajitas contain onion, peppers, and cauliflower. Why cauliflower? Isn’t very Mexican right?! Nope, it’s not but I love roasted cauliflower. The flavor and texture are amazing. However, you can vary this fajita recipe as per your liking and add different vegetables. Maybe you will like the following ones:

  • Portobello mushrooms
  • Carrots
  • Zucchini

Instructions

  • This recipe has a video for easy instructions (see below).

FAQs

Are fajita veggies cooked in oil? ›

Cook the fajita veggies in hot oil in a cast iron skillet over medium-high heat. For firmer veggies, cook for about 5 to 7 minutes. I prefer to cook the veggies for 10 to 15 minutes so that they're softer and more charred. Add the seasonings in the beginning and sprinkle with salt throughout the cooking process.

Should fajita veggies be crunchy? ›

Get my tips for perfectly seasoned and cooked vegetables. There are two secrets to perfect fajita vegetables: (1) Stop cooking while they still look a little crunchy, and (2) Season them well.

Why do you roast vegetables in oil? ›

Not only does the oil help the vegetables cook more evenly and crisp up in the oven, but it also adds a rich flavor that makes roasted vegetables irresistible.

How do you keep fajita vegetables from getting soggy? ›

Use poblanos instead. Less water and can stand a long time in the pan without turning to mush. Edit to add: I use a dry pan and oil my veggies lightly, char them slightly, pull them out and then cook my meat before adding the veggies back in.

Are fajita veggies anti inflammatory? ›

Grilled or Sautéed Onions & Peppers in Fajitas

Both onions and peppers contain a lot of vitamin C which is a metabolized protein that helps boost our immune system. Onions are rich in antioxidants and work as an anti-inflammatory.

Do you normally put cheese on fajitas? ›

In restaurants, the meat is usually cooked with onions and bell peppers. Popular condiments include shredded lettuce, sour cream, guacamole, salsa, pico de gallo, shredded cheese, refried beans, and diced tomatoes.

What kind of onion is good for fajitas? ›

There's no one-size-fits-all answer to choosing the right onion for your fajitas. You can go for the traditional white or yellow onions, offering a more savory option, or experiment with sweet onions like Vidalia or Walla Walla to add a subtle sweetness to your dish.

Are chipotle fajita veggies cooked in oil? ›

Fajita veggies at chipotle are simply made with bell peppers, onions, oregano, oil, and salt.

Should I use oil when cooking vegetables? ›

The oil carries flavors and heat, and helps keep the vegetables from sticking. If they've already begun to stick before you think of it, pour a little water or stock or wine into the pan and deglaze (rub all over the pan with a wooden spoon to dislodge and melt the caramelized vegetable sugars into the boiling liquid).

Are vegetables still healthy when cooked in oil? ›

Sautéing quickly in a small amount of healthy oil, such as olive oil, helps vegetables maintain their nutrient content. It's crucial to use medium heat to avoid nutrient degradation and to keep cooking time short. This method enhances the flavor and texture of vegetables while preserving their nutritional value.

Do you saute vegetables in oil? ›

Heat a skillet or pan over medium-high heat with a splash of olive oil or butter to coat the bottom. Voila! You're ready to get started. Vegetables are ideal candidates for sauteing as it works best for food that cooks for a short amount of time.
