Why you’ll love these veggie packed fajitas

Our fajitas are packed full of different veggies and spices. They will tantalize your taste buds and get even your pickiest eaters to enjoy their vegetables.

You’ll also love that these veggie filled treats are naturally vegan. If you don’t follow a vegan diet though, you can easily top them with sour cream or your favorite cheese. 

For ease, we provide you with two different ways to cook them. You can place them in your oven or you can use your air fryer to create perfectly charred and slightly crispy veggies for your filling. 

Since these are homemade, you can control what goes in them. You can add additional veggies if you like or even omit some of our suggestions without drastically altering the recipe. 

Ingredients for Vegetable Fajita

When you are hungry for fajitas, you’ll need the following ingredients: 

• Olive oil -you could use a different light tasting oil if you prefer
• Garlic powder
• Onion powder
• Paprika
• Cumin powder
• Chili powder
• Salt
• Red, green, and yellow bell peppers - you’ll need to cut them into stripes
• Onion 
• Portobello mushrooms
• Tortillas
• Additional toppings - guacamole, salsa, sour cream or vegan crema, chopped fresh cilantro (coriander), or cheese

How to make Fajitas

• First, mix together the olive oil and all of the spices in a small bowl or measuring cup. Once mixed, set the bowl aside.
• Next, place the vegetables into a large mixing bowl and then pour the spiced olive oil on top of them. We often use tongs to mix until the veggies are all coated in the spices.

• Once the veggies are ready, you need to either line a baking sheet or your air fryer basket with parchment paper. Next, spread the veggies over the paper.
• When using the oven, preheat it to 450°F and then cook for about 20 minutes or until the vegetables have softened and browned. 
• If you want to use your air fryer, first preheat it to 200C / 390F and then cook for 15 minutes.Half way through frying them, carefully open the fryer up to mix the vegetables.

• Whether you use the oven or fryer, the veggies are ready when they become juicy and appear a bit charred. If they are not to your desired level of doneness, you can cook them for about 5 more minutes or until they reach your desired level of perfection.
• Serve the fajitas in flour or corn tortillas alongside your favorite sides and with your favorite toppings.

Pro tips and tricks to make best Vegetable Fajita

If you are ready to make fajitas like a pro, check out these tips below:

• Sub in as many additional veggies as you like. Just try to cut them into similar size pieces or stripes whenever possible.
• Don’t skip the onions or peppers, these provide part of their great flavor.
• When using an air fryer, always make sure to leave a bit of room between veggies. Air needs to hit each side of veggies to provide uniform charring and cooking.

What is the best fajitas seasoning?

When you buy a premade packet or bottle of fajita seasoning, you are often buying salt mixed with a few spices. And though this may provide some flavor, it is often very salty. 

But if you are looking for good flavor and far less salt, you can make your own seasoning at home using spices you probably already have on hand. All you need for delicious flavor is garlic powder, onion powder, paprika, cumin powder, chili powder, and a small amount of salt.

What are the best vegetables to use for veggie fajitas?

Without question, you really can’t make a fajita without bell peppers and onions. But they are really just a starting point.

In our recipe, we use mushrooms as an added veggie. For added flavors, textures, or nutrients, you could easily add veggies like:

• zucchini 
• corn 
• broccoli
• squash 
• black beans
• potatoes
• jalapenos 

Tips, tricks, and substitutions

When making homemade fajitas, you can follow these easy tips to make your life a bit easier:

• If you can’t find different colored peppers, you can use the same variety of peppers.
• For added spice, thinly slice a jalapeno pepper.
• When baking or cooking in the air fryer, leave them in a bit longer for more charring.
• Try to make the pepper and onion slices about the same size for uniform cooking.
• Add as many toppings and extras as you like to dress them up.

What to serve with Vegetable Fajita?

Fajitas pair well with a lot of different Tex-Mex inspired foods. 

For rice lovers, you could serve them alongside our Spanish Rice or our spicy Fiesta Rice.

If you love beans, you could try our homemade refried beans recipe. Or if you are looking for a lower carb option with plenty of flavor, you could serve them with our Mexican  Cauliflower Rice Bowl.

Do I need a skillet to cook Fajitas?

Some recipes call for cooking fajitas on the stovetop using a cast iron or other heavy iron skillet. You may have even seen a server bring out a sizzling skillet full of fajita filling at a local restaurant. And while this is one great way to cook the filling, you don’t have to use a skillet to get a great tasting fajita. 

In our recipe, we use either an air fryer or oven to crisp up and roast the veggie filling. The slight charring provides additional flavor that is not always easy to get from a skillet.

What tortillas are best with Vegetable Fajita?

You can use your favorite type of tortilla when making fajitas. Both flour and corn tortilla work very well, so it really comes down to a matter of taste and texture.

Flour tortillas tend to be softer and have a mild flavor. Corn tortillas are often a bit tougher and can break a bit more easily. They also have a slight corn flavor to them.

Though not traditional for fajitas, you could also use crunchy taco shells if you are in a pinch or just like the flavor. 

How to store veggie fajitas

When storing veggie fajitas, it is a good idea to keep the veggies and any leftover tortillas separate. You should place any tortillas back in their bag or in any air tight container.

You can then place the fajita filling in an airtight container. Once sealed, you can place the container in the fridge for up to about 5 days. 

How long does this vegetable fajita recipe keep?

The veggies should stay fresh in the fridge for up to five days. The sooner you eat them, the fresher they will taste. You can make these ahead to serve for lunch during the week or as a very quick leftovers night on a busy weeknight.

How to reheat vegetable fajita?

It is super easy to reheat the filling. You can place the container or an individual serving in the microwave and cook for about 2 minutes or until heated through.

Or if you prefer, you could gently reheat them over medium low heat on the stove top. If you use the stove top, make sure to gently stir them as they heat through.
