How to Make Fajita Veggies

Once you’ve mixed the marinade together, this recipe couldn’t be simpler to make. Here’s what you need to do:

• Slice your veggies! I like to cut the onions into wedges and the peppers into thin slices. Just stem the mushrooms and leave the caps whole.
• Drizzle on the marinade. Toss the peppers with a scant tablespoon of the marinade, and pour the remaining marinade over the mushrooms and onions. Rub a splash of balsamic vinegar onto the mushrooms too.
• It’s time to grill! Preheat the grill with a cast iron skillet or grill pan on one side. When it’s hot, put the pepper slices in the hot skillet and grill the mushrooms and onions directly on the grill grates.
• Don’t forget to flip halfway… Cook the veggies until they soften and char marks form on the onions and mushrooms, flipping halfway through. I use tongs to toss the peppers in the skillet and cook until they get a little char too.

Celebrate summer with these rainbow fajita veggies! Incredibly easy and insanely flavorful, this veggie fajita recipe is perfect for entertaining.

After you try these rainbow fajita veggies, you’ll never need to visit Chipotle again. These guys are super fresh and colorful, tangy, smoky, and perfectly charred. They’d be a great addition to a burrito or bowl, but for my money, they make a great main dish too. Served alongside tortillas and fresh fixings like guac and salsa, this veggie fajita recipe is a delicious quick and easy dinner.

These fajita veggies would make a great weeknight dinner, but they’re perfect for parties, too! Not only can you make them in under 30 minutes, but they’re also ideal for serving a crowd because everyone can customize their final dish to their liking. Jack’s not a fan of avocado (crazy, I know), so he skipped it. I loaded mine up with all the fixings and generous squeezes of lime, and the next day, I enjoyed the leftovers in a burrito bowl with rice, beans, arugula, and lots of guac and salsa.

Veggie Fajita Recipe Ingredients

• Sweet bell peppers – I love to use a mix of colors. Red, yellow, green, and orange peppers (even though they’re not pictured) would be great.
• Red onion – For bold purple color and savory flavor.
• Portobello mushrooms – Thanks to their hearty, meaty texture, they make a delicious veggie fajita recipe without any meat!

You don’t need a fancy fajita seasoning mix to pack these veggies with flavor! I use a simple 5-ingredient marinade. It’s a lightly spicy mix of avocado oil, garlic, chili powder, cumin, and sea salt. I use Simply Nature Avocado Oil here because I like its neutral taste with the Tex Mex spices. In addition, it’s great for grilling because it has a high smoke point, so you don’t need to worry about putting it on the hot grill.

Ingredients

• 3 multi-colored peppers, stemmed and sliced into strips
• 3 portobello mushrooms, stemmed and wiped clean
• 1 red onion, sliced into wedges
• 2 tablespoons avocado oil
• 2 garlic cloves, chopped
• ½ teaspoon chili powder, more to taste
• ½ teaspoon cumin
• ½ teaspoon sea salt, more to taste
• Splash of balsamic vinegar
• 2 limes, sliced into wedges
• Freshly ground black pepper

For serving

• 8 Flour or Corn Tortillas
• Guacamole or avocado slices squeezed with lime
• Pickled Jalapeños or sliced plain jalapeños
• Diced tomatoes or Pico de Gallo
• Cilantro
• Tomatillo Salsa or Pineapple Salsa

Instructions

• Heat a grill to medium heat with a 12-inch cast-iron skillet (or grill pan) inside.
• Arrange the peppers on a tray and the mushrooms and onion wedges on a separate rimmed plate. In a small bowl, whisk together the avocado oil, garlic, chili powder, cumin, salt, and several grinds of pepper. Drizzle 1 scant tablespoon of the mixture over the peppers and toss to coat. Drizzle the remaining marinade over the mushrooms and onions. Drizzle the mushrooms with a splash of balsamic vinegar and use your hands to coat the mushrooms on both sides.
• Grill the peppers in the cast-iron pan for 8 to 10 minutes, tossing occasionally, until charred and soft. Be careful not to overfill the pan or the veggies won’t char on the edges – cook them in 2 batches, if necessary. Grill the mushrooms and onion wedges directly on the grill for about 4 minutes about per side. Remove everything from the grill, using a potholder to remove the cast-iron pan. Squeeze the juice of ½ lime over the peppers and season with salt, pepper, and more chili powder, to taste. Slice the mushrooms into strips and place on a serving dish. Transfer the onions and the peppers to a serving skillet or large platter.
• Serve with the tortillas, guacamole, jalapenos, tomatoes, cilantro, salsa, and remaining lime wedges for serving.
