These savory fajita veggies make a flavorful, low-carb side for grilled meats, and they also shine wrapped in a warm tortilla for excellent vegetarian fajitas.

What are Fajita Veggies?
Fajita veggies are the classic accompaniment to sizzling fajitas: sliced onions and bell peppers cooked until tender alongside other vegetables and a bold spice mix. They’re typically sautéed or grilled with chili powder, paprika, cumin and finished with a squeeze of lime to brighten the flavors.
This version is my go-to skillet recipe and pairs well with grilled pork tenderloin, shrimp, or a jalapeño-lime salmon.
Fajita Veggie Ingredients
Here’s a concise overview of what you’ll need. Scroll down for the complete recipe and instructions.
- Vegetables: sliced bell peppers (use a mix of colors), red onion, jalapeños, garlic and mushrooms.
- Fat: olive oil, avocado oil, butter or ghee.
- Fajita seasoning: a homemade blend is listed below, or substitute taco seasoning.
- Lime: fresh lime adds the finishing touch.


How to Make the Best Fajita Veggies
- Slice the vegetables into thin strips so they’re easy to fill into tortillas and each bite has a balanced mix.
- Don’t skip the lime: citrus is a defining flavor for fajitas and brightens the whole dish.
- Cook in batches if necessary. Avoid overcrowding the pan so the vegetables brown evenly and retain some texture.

Fajita Seasoning
I usually use a homemade fajita seasoning for these veggies, but taco seasoning works fine too. You’ll need about 2 tablespoons of the blend for the vegetables. This mix is versatile and great on chicken, steak, seafood or other vegetables.
Fajita seasoning blend
- 1/4 cup chili powder
- 2 tablespoons paprika
- 1 tablespoon cumin
- 1 tablespoon onion powder
- 1 tablespoon garlic powder
- 2 teaspoons oregano
- 1 teaspoon salt
- 1 teaspoon black pepper
How to Serve These Veggies
These fajita veggies are excellent wrapped in a warm corn or flour tortilla with cheese, sour cream and salsa for a satisfying vegetarian fajita. They also work well in several other ways:
- Serve alongside grilled salmon or shrimp for a complete, heart-healthy meal.
- Pair with chimichangas or other Mexican-style mains as a colorful side.
- Use them as a filling for lettuce wraps or on top of grain bowls for extra flavor and texture.
