Quick vegetarian fajitas skillet is a hearty, filling and delicious skillet meal that's just 6 ingredients and ready in 25 minutes!

Filled with black beans, peppers, zucchini and green chilies, these veggie fajitas are great served in warm tortillas or over rice.

Fajita night is a regular thing in our house, and I love finding fun variations.

Sometimes that's fajita chicken pasta or skillet shrimp fajitas.

I also love making vegetarian versions of some of our favorite dishes. See these vegetarian sweet potato and black bean enchiladas and slow cooker vegetarian curry.

So today we're making quick skillet vegetarian fajitas. 

These are loaded with black beans, peppers, zucchini and green chilies and they are soooo good!

We aren't even vegetarian and we adore these. They are healthy, hearty, filling and just so flavorful.

Also, if you have a family where some do follow a vegetarian diet and others do not, it's easy to add some seared shrimp or rotisserie chicken to this mix after reserving some and have it work for everyone.

Plus, this recipe is just 6 ingredients and about 25 minutes to make. So easy for any night of the week!

OK, let's get cooking.

Ingredients laid out in separate bowls for making a black bean and veggie fajitas skillet.

Ingredient Notes:

Peppers: Using two different colored bell peppers adds some great flavor and color interest. Feel free to choose from green, yellow, red and orange bell peppers. (Or substitute a mix of the cute mini sweet peppers from the bag.)

Zucchini: These add great texture and help bulk up the fajitas and give them more heft. 

Beans: Black beans are our favorite for these fajitas, but you could certainly try them with pinto beans if you prefer those.

Fajita seasoning: We love homemade fajita seasoning, which is so very easy to mix up yourself and has great, fresh flavor, but you can certainly use a store-bought mix.

As for serving, we love loading these up into warmed tortillas and adding ALL the toppings! 

Cheese, salsa, guacamole or avocado, shredded lettuce, Greek yogurt, yes please to all!

To note: These are vegan and gluten free as is, depending on how you serve them. Just in case that's helpful.

You can also serve these fajitas with steamed rice to make a vegetarian fajita rice bowl. I love doing that with the leftovers for lunch later in the week.

And if you need a side dish to bulk up and round out your meal, this Mexican coleslaw would be amazing, as would just a simple green salad for something light and fresh and green.

I hope you give these a try too for a quick and easy vegetarian dinner that's sure to satisfy!

Enjoy!

XO,

Kathryn

Ingredients

  • 1 tablespoon canola oil, divided
  • 1 medium white onion, sliced in ¼-inch thick slices
  • 2 medium bell peppers (mixed colors), sliced in ¼-inch thick slices
  • 1 medium zucchini, halved both ways and cut into long spears about ¼ inch thick
  • 1 (15 oz) can black beans, rinsed and drained
  • 1 (4 oz) can diced green chiles
  • 2 tablespoons fajita seasoning, divided

For serving:

  • Warmed tortilla shells

Optional toppings:

  • Shredded cheddar cheese, shredded lettuce, salsa, diced avocado or guacamole, sour cream or Greek yogurt, chopped fresh cilantro, lime wedges, hot sauce, etc.

Instructions

  • Heat ½ tablespoon of the canola oil in a large skillet over medium-high heat.
  • Add the sliced onion and one of the bell peppers to the pan. (We're cooking in batches so we get a nice char on the veggies instead of overcrowding the pan and just steaming them.) Sprinkle with ½ tablespoon of fajita seasoning. Cook, stirring occasionally, until the veggies are tender and lightly charred, about 6-7 minutes. Remove to a bowl.
  • Heat the remaining ½ tablespoon of canola oil in the same pan. Add the other sliced bell pepper and the zucchini to the pan, along with ½ tablespoon of fajita seasoning. Cook, stirring occasionally, until the veggies are tender and lightly charred, about 6-7 minutes.
  • Add the onion and pepper back to the pan and add the black beans, diced green chilies and remaining tablespoon of fajita seasoning. Stir to mix well. Cook 1-2 minutes, until warmed through.
  • Serve immediately with tortilla shells and desired toppings.
