I don’t know about you, but I love fajitas! It doesn’t matter if it’s ground beef fajitas, baked chicken fajitas, or a plant-based option such as delicious portobello fajitas.

My favorite part of fajitas is all the delicious vegetables that come with the protein. If you have ever been to Chipotle, every time I am asking for extra fajita veggies.

My children don’t love vegetables as much as I do, however, there's one exception to this rule - Fajita Veggies! These sizzling, colorful long strips of bell peppers and onions have somehow won over their picky taste buds.

I like my fajita veggies to be tender, crisp, and full of color. For that reason, I often add yellow bell peppers along with green, red, and even orange peppers.

If you’re looking to taste your favorite Mexican restaurant at home, these fajita vegetables are the ultimate way to get it.

This healthy side dish recipe is always a staple when I'm cooking Mexican-inspired cuisine. Whether I’m whipping up sheet pan steak fajitas, black bean tostadas, or chicken burrito bowls, these delicious fajita veggies always find their way onto the table.

Why You’ll Love My Fajita Veggies Recipe

  • Simple to make: One of my favorite things about this fajita vegetable recipe is its simplicity. It doesn’t take a million spices to achieve that mouthwatering flavor, just veggies, oregano, salt, and a little olive oil.
  • Fast and easy: Did I mention they come together in under 10 minutes? That’s perfect for those busy weeknights when you don’t have a lot of time to prepare dinner.
  • Perfect accompaniment: Serve it alongside classic fajitas, chicken fajita bowls, a burrito bowl, tacos, or rice and beans with all your favorite toppings at your next weeknight family dinner or social gathering.

Key Ingredients

To make these homemade fajita veggies, you will need the following essential ingredients:

  • Bell peppers. I like to use green peppers along with yellow and red bell peppers for a nice pop of color, but you can use any combination of bell peppers you like. Make sure to cut them into thin strips so they cook thoroughly without burning.
  • Onions. Red onions are perfect for their subtle sweetness and vibrant pop of color that pairs beautifully with brightly colored peppers. You can also use white or yellow onions (or even a mixture) if needed.
  • Spices. All you need is oregano and salt. Nice and simple! The veggies have plenty of flavor all on their own, but these basic spices add a delicious boost of flavor that takes these fajita vegetables to the next level.
  • Olive oil. I like to use olive oil, but you can also use avocado oil.

How to Make Fajita Veggies

This easy recipe only takes ten minutes to make! For full instructions, print the recipe card below.

  1. After all your veggies are sliced into thin strips, you'll cook them in a large pan on the stove (I prefer to use a cast iron skillet).
  2. Make sure your pan is HOT to get a nice char on your vegetables. The idea is to get them tender yet crisp with some beautiful caramelization. If you notice the veggies are starting to char too much, add a little water.
  3. Season the veggies with salt, pepper, and oregano.

Recipe Variations

Looking for a twist? Here are some of my favorite ways to switch up this recipe:

  • Spice it up. If you’re a lover of spicy food, try adding chili powder, red pepper flakes, or sliced jalapenos to bring some heat to this dish.
  • Change up the spices. While we keep this recipe simple with oregano and salt, you can easily add different flavors to fit with a variety of dishes. Add taco seasoning, a fajita seasoning blend, cumin, garlic powder, paprika, or onion powder.
  • Swap out the veggies. Not a fan of peppers? No problem. Try swapping them out for thinly sliced zucchini or portobello mushrooms, or cook the onions on their own.
  • Add fresh herbs. To enhance the flavor of these tasty veggies, try adding chopped herbs like fresh cilantro, parsley, or basil.
  • Make a fajita buffet. For a delicious fajita spread, make some tasty slow cooker chicken fajitas and pair them with extra fajita veggies, guacamole, refried beans, and cilantro lime rice.
  • Add the perfect drink. When cooking up a Mexican-inspired feast, it’s only fitting to pair it with a delicious beverage. Try my Easy Mojitos or Skinny Margaritas.
  • Make it more filling: Add black beans or pinto beans to the veggies for a meatless taco or burrito filling. For a tasty meal, all you need are warm flour tortillas, salsa, shredded cheese, and sour cream.
