 Fajita Vegetables

Fajita Vegetables are a quick and easy side dish we make with all of our latin themed recipes. With tender crisp vegetables and lean proteins you can add a lot of flavor, crunch (those red onions even pop with crisp and juicy textures).

Every weekend we work with base recipes around here to prepare for the upcoming week. I roast vegetables, grill vegetables (if the weather permits) and cook off a bunch of them in the cast iron skillet to bulk up our meals throughout the week.

These fajita vegetables are an easy prep recipe because the peppers and onions taste great even when made ahead of time and we end up using them throughout the whole week for breakfast, lunch and dinner.

Fajita vegetables


My favorite secret to make these fajita veggies look a little more like a fancy restaurant? I use the mini bell peppers that come in the bag so the strips are smaller and sized more similarly to the red onion slices. This also allows for a faster cook time.

Yes, the mini bell peppers are going to be marginally more work to prep and slightly more expensive, but if you’re hosting a dinner these fajita veggies will look and taste fantastic served along side them.

Recipes that use fajita veggies:

  • Your favorite fajitas, burritos, burrito bowls, tacos, nachos, quesadillas or taco salads.
  • Omelets, chilaquiles, breakfast scramble plates and any other breakfast favorites.
  • Seasoned pasta recipes like taco pasta or even cajun pasta recipes.
  • Your favorite sandwiches *these are amazing in grilled chicken sandwiches*

Vegetables included in Fajita veggies:

  • bell peppers of all varieties
  • red onions (my favorite), yellow onion, green onions
  • thinly sliced jalapenos or pasilla peppers
  • thinly sliced portabello mushrooms
  • quartered roma tomatoes
  • cilantro

How to make Fajita Vegetables:

The classic way is to use a cast iron skillet or griddle to sear the vegetables quickly while keeping them tender-crisp. You can also roast them off on a sheet pan at 400 degrees for 18-20 minutes or use a grill pan on your grill to cook them over medium heat.
