Fajita Veggies Recipe (Chipotle Copycat)

While most believe the meat is what makes a good taco, I would have to argue that no taco is complete without a heap of fajita veggies on top!

Thankfully, it turns out that this simple and delicious accompaniment is super easy to make at home.

The subtle sweetness of the peppers and onions comes through when they’re tossed in a homemade Mexican seasoning mix and sautéed in a skillet until a gorgeous, crusty char forms.

They’re so full of flavor that you can even skip the meat entirely, and go vegetarian or vegan with dinner!

And if you’re a fan of Chipotle Mexican Grill, then you’re in luck. Because these delicious fajita veggies taste just as good, if not better than the restaurant version side dish! Once you make this copycat Chipotle fajita veggies recipe, there’s no going back.

Ingredients

  • Bell peppers. Using a mix of red, yellow, and green peppers creates a beautiful effect and gives a slightly more complex flavor. But you can go with all one color, if preferred.
  • Onion. Choose a red onion for its strong, pungent flavor. However, you can sub a sweet or white onion.
  • Oil. A neutral cooking oil with a high smoke point, such as avocado oil, is ideal. If it’s all that’s available, vegetable or olive oil will also do.
  • Garlic. Fresh garlic is preferred, however for each clove, ⅛-teaspoon of garlic powder may be substituted. 
  • Fajita Seasoning. A homemade mix of spices typical in Mexican cuisine, including chili powder, paprika, cumin, oregano, salt, and pepper.

How to Make Fajita Veggies

Please see the recipe card below for more detailed ingredient amounts.

1. Slice Peppers

Using a sharp chef’s knife, cut from the top to the bottom next to the core of the pepper. Repeat until only the core remains. Discard the core, and repeat with the remaining peppers. 

Trim away any lingering pieces of white membrane attached to the pieces of bell pepper flesh. Thinly slice the remaining pepper sections into ¼-inch thick strips.

2. Cut Onions

Before cutting, peel away as many layers of the thin, papery skin as possible from the onion by hand. Use a sharp knife to cut about ½- to 1-inch from the top and bottom of the onion.

Make a shallow incision into the thin outer layer of the onion, and peel that piece away as well. Place the onion flat-side down on the cutting board and slice it in half through the top, cutting through the core.

Lay each half, cut-side down, onto the board and thinly slice them lengthwise into ¼-inch thick strips. You should end up with pieces roughly the same size as the sliced peppers.

Red onions are cut into strips just like bell peppers.

3. Cook in Cast-Iron Skillet

Pour your oil into a large cast-iron pan heated on medium-high. When warm, add the garlic, and sauté it for 30-60 seconds, or until it becomes fragrant and begins to brown. Watch it carefully, as it can burn very easily. (If needed, reduce to medium heat.)

Add the thin strips of bell peppers, sliced large red onion, and homemade Fajita Seasoning, mixing to combine them. Cook over medium-high heat for 7-8 minutes, stirring occasionally to ensure even cooking.

For the best results and a little more of a charred effect, let the colorful vegetables sit for a minute or two between stirring. Charring helps to caramelize the natural sugars inside the vegetables, enhancing their flavors.

Keep a close eye on them, however, as they can very quickly go from charred to burned in the large cast-iron skillet!

4. Stir and Serve

When the vegetables are finished cooking, sample a few pieces and adjust the seasoning level to taste, if needed. 

Remove the skillet from the heat and stir the vegetables very well, trying to get up any browned bits clinging to the pan. 

Serve the fajita vegetables immediately. They can be enjoyed on their own or in a variety of dishes. Use these delicious sautéed peppers and onions with vibrant color as a topping for tacos, burrito rice bowls, veggie fajita salads, nachos, or even on a burger or sandwich!

Vegetables are cooked until tender in a cast-iron skillet.

FAQs

How do you properly serve fajitas?

Fajitas are traditionally served on flour or corn tortillas with sliced chicken or beef, peppers, and onions. They can include any preferred toppings such as rice, black beans, cheese, sour cream, corn, pico de gallo, cilantro, lime juice, and more!

What can I use instead of peppers in fajitas?

The peppers in fajitas can be substituted with any other preferred option such as zucchini, eggplant, or portobello mushrooms. Keep in mind that this may affect cooking times, which you should adjust accordingly.

What is the difference between a fajita and a taco?

Fajitas are generally defined by the presence of grilled or sautéed vegetables like peppers and onions, whereas tacos are most often served with finely chopped raw ingredients. The two concepts may be combined, however, as fajita vegetables make for an excellent topping on tacos!

Recipe Tips

  • Experiment with ingredients. Trying out different vegetable combinations for your fajita mix is a great way to explore new flavors. Eggplant, mushrooms, squash, and zucchini all make great additions.
  • Go for cast-iron. Using a cast-iron skillet is ideal for this recipe because it can retain the high heat needed for charring. 
  • Get colorful… or not. Using multiple types of bell pepper is a great way to add color contrast to your fajitas, but not necessary.
  • Add a little spice. For an extra kick of heat, try including a hotter variety of peppers such as jalapeños or poblanos.
  • Let them sit. Allowing the fajita vegetables to char a bit in the pan caramelizes the natural sugars in them, enhancing their flavor.

Notes

  • How to Slice Bell Peppers: Find a bulbous part of the bell pepper and cut this off. Locate the white membrane and continue cutting off the bell pepper flesh while keeping the white part attached to the seeds. You should end up with 4-5 pieces of bell pepper and the core with the seeds and membranes still attached. Repeat this with the remaining peppers. Trim and remove any white membranes, or pith, from the bell pepper flesh. Thinly slice into ¼-inch thick pieces.
  • How to Slice Onions: Cut and remove ½-1 inch from both ends of the onion. Make a shallow incision into the outer layer and then peel it off. Place the onion flat-side down onto the cutting board and slice it in half. Put the onion half cut-side down onto the board and cut it lengthwise into ¼-inch thick slices. Repeat this with the other half of the onion.
Prep-Ahead Instructions:
The vegetables can be sliced and stored in separate airtight containers in the fridge in advance. The onions may be cut up to 7 days ahead, and the peppers up to 3 days ahead.
Storage Directions:
Cooked fajita veggies may be stored in an airtight container in the refrigerator for up to 5 days. Leftovers can be frozen in a freezer-safe zip-top bag with all the air removed, to help prevent freezer burn. They can be stored in this manner for up to 3-6 months. Frozen fajita vegetables should be thawed in the fridge overnight, but may also be defrosted in the microwave at 50% power. To warm them, place them back into a large skillet with a tiny bit of water and sauté over medium-high heat for roughly 3 minutes, or until heated through.
Recipe Tips:
  • Experiment with ingredients. Trying out different vegetable combinations for your fajita mix is a great way to explore new flavors. Eggplant, mushrooms, squash, and zucchini all make great additions.
  • Go for cast-iron. Using a cast-iron skillet is ideal for this recipe because it can retain the high heat needed for charring. 
  • Get colorful… or not. Using multiple types of bell pepper is a great way to add color contrast to your fajitas, but not necessary.
  • Add a little spice. For an extra kick of heat, try including a hotter variety of peppers such as jalapeños or poblanos.
