All of the ingredients are easy to find at your local grocery store. You may already have all of the ingredients you need in your fridge and pantry.
- Bell Peppers: You can use a mix of any color bell peppers. I love using a mix of red, yellow and green bell peppers for color contrast. Ue fresh bell peppers for the best results.
- Onion: Use red onions or yellow onions. I prefer the red onions for fajitas due to its mild flavor and vibrant color. But yellow onions are a great choice too with a natural sweetness that pairs well with the peppers.
- Olive Oil: Use high quality extra virgin olive oil for the best flavor. You can also substitute with avocado oil, if desired.
- Seasonings: You will need chili powder, ground cumin, dried oregano, garlic powder, paprika, salt and pepper for the homemade fajita seasoning. You can also substitute the seasonings for store-bought fajita seasoning.
- (Optional): A pinch of cayenne and freshly squeezed lime juice are optional but add delicious flavor.
I usually use a standard cast iron skillet for this recipe. The cast iron pan heats evenly and allows the veggies to get slightly caramelized yet crisp and tender. You will also get that classic fajita sizzle. You can also use an enameled cast iron skillet or another type of large skillet.
How to Make Fajita Veggies
Fajitas are so easy to make. Here are the three steps you need to follow:
- Prepare the pan and vegetables: Heat the oil in a large skillet set over medium heat. Slice the bell peppers and onions into thin strips.
- Make the fajita seasoning: Combine all of the ingredients for the seasoning in a small bowl and mix well.
- Cook the veggies: Add the sliced bell peppers and onions to the preheated skillet. Sprinkle the seasoning over the veggies. Saute for 4 to 8 minutes, stirring frequently, until the veggies are crisp tender, or softened to your liking. Squeeze the lime juice over the sautéed peppers and onions and toss to combine, if desired. Remove from the heat and serve immediately.

Fajita Veggies in the Oven (On a Sheet Pan)
You can cook the veggies on a sheet pan in the oven instead of on the stovetop. Simply preheat the oven to 425 degrees Fahrenheit. Stir together all of the ingredients in a large bowl. Line a baking sheet with parchment paper. Add the veggies in a single layer. Roast in the preheated oven for 15 minutes, then stir and continue cooking for another 10 minutes, until tender.
- Slice the bell peppers into thin, even-sized slices. This will ensure they cook evenly.
- Feed a crowd! Fajitas are a great option for dinner parties or to feed a large family. You can double or triple to recipe and cook in batches to feed a crowd.
- Storage: Store leftovers in an airtight container in the refrigerator for up to 2 days. You can reheat in a skillet or in the microwave.
- Make chicken fajitas, steak fajitas or shrimp fajitas! Serve the protein and veggies with flour or corn tortillas.
- Make veggie fajitas: Simply add the fajita veggies to tortillas or add sliced mushrooms to the bell peppers and onions while cooking. You can also serve the fajita veggies with pinto beans or black beans.
- Add toppings: Serve the bell peppers and onions over tortillas and load up the toppings. Sour cream, guacamole, sliced jalapenos, fresh tomatoes, hot sauce and cilantro are great choices.
- Serve them over a ground beef burrito bowl, tacos or in a quesadilla.
