Fajita Veggies

You can have the best grilled chicken, steak, or shrimp in your tortilla – but if the veggies aren’t good, then the whole fajita suffers! That’s why I always stick to the classics when it comes to my Fajita Veggies. Red onions, bell peppers, and mushrooms are all you need to make your fajitas the best that they can be. Well, those veggies and some flavorful add-ins, of course.

Aside from the fresh veggies, one of the most important ingredients here is the Homemade Fajita Seasoning. While you can certainly use your favorite store bought brand, I highly recommend making my simple mix of spices for these veggies.

My homemade blend lends a ton of flavor to the veggies, while I’ve found that many store bought brands lend mainly saltiness to everything they touch.

You’ll also need lime juice in the mix to really get the freshest flavor possible! For the BEST results, it’s vital to squeeze the lime (or limes) yourself to render the freshest juice.

Lime juice from concentrate just isn’t the same, and you can absolutely taste the difference. Any time I’ve used bottled lime juice on a whim, it always leaves a weird aftertaste. When making something as fresh as these Fajita Veggies, we don’t want any of that!

The ingredients for fajita veggies are presented on a cutting board.

How to Make Fajita Vegetables

  1. Heat the oil. Heat the olive oil in a large skillet over medium high heat.
  2. Cook the onions. Add the onions to the pan and cook until beginning to soften.
  3. Cook the peppers. Stir in the peppers and continue to cook until the peppers soften.
  4. Make it fragrant. Add the garlic and cook for 1 minute longer.
  5. Cook the mushrooms. Stir in the mushrooms and turn the heat to high. Continue to cook until the vegetables begin to char then turn the heat to low.
  6. Make it flavorful. Stir in the fajita seasoning, lime juice and zest. Cook for 1-2 minutes longer.
  7. Enjoy! Serve immediately with lime wedges, cilantro and hot sauce, if desired.

Are Fajita Veggies spicy?

When made with my favorite homemade fajita seasoning, these veggies have a little kick to them, but they’re definitely not too spicy. There’s chili powder and cayenne pepper in the seasoning mix that add heat, but they’re very balanced out by the other handful of spices. However, if you’d like to make these veggies spicy, it’s easy to do! Just sprinkle in more chili powder and/or cayenne until the spice level is to your liking.

How long will Fajita Veggies stay fresh?

In an airtight container in the fridge, any leftover Fajita Veggies you have will stay fresh for up to 3 days. Just make sure they’ve cooled to room temperature before storing. Also, I recommend reheating them in the pan as opposed to the microwave! The microwave will zap the texture right out of them and make these veggies pretty mushy.

Can I change up the bell peppers?

Absolutely! Many people prefer green bell peppers in their fajitas as opposed to red, yellow, or orange. Green peppers cook the same, so you can follow the same instructions that I have listed for my peppers. Just note that the flavor will be a little bit different. Red, yellow, and orange peppers have a more natural sweetness to them, while green peppers are notably more bitter.
