Sheet Pan Skirt Steak Fajitas

For a super simple and healthy dinner, these sheet pan skirt steak fajitas are full of flavor with minimal effort!

Move over Taco Tuesday- time to meet Fajita Friday!

Fajitas always make me think of a sizzling skillet at Chilis. Tender and juicy steak, with grilled veggies. This effortless weeknight meal, can quickly be adjusted to feed a crowd! And clean up is always easy!  

This recipe is a true original- the first base meat used in fajitas was skirt steak!

And, just like tacos- fajitas are so easily customizable! Beef. Chicken. Shrimp. Sliced, grilled peppers and onions are the norm- but, no one is watching! Go ahead and add your favorite veggies! I created my own fajita marinade/seasoning. You can also use a prepackaged fajita seasoning or even taco seasoning. This dish is already fairly low in carbs, but you can serve solo or atop a salad.

You can easily cook the steak to your liking too! By using the broiler and allowing the meat to rest while the veggies roast, you can slice and add back to the oven for a few minutes, to reach your desired doneness.

I marinated the steak for 30 minutes for added flavor. After marinating the meat, dinner can be on the table in 30 minutes or less!

To save even more time...cut veggies ahead of time- you can even freeze!

What is the difference between a fajita and a taco?

Overall, fajitas and tacos are very similar. Fajitas have grilled meat and veggies that are cut into strips. In a taco, the veggies are usually diced and served raw.


Are fajitas healthy?

You bet! Well, it depends on the ingredients used, but fajitas can definitely be part of a healthy diet! I used steak, but chicken and shrimp are other great options! And- have fun with some toppings, just don't go crazy with the cheese and sour cream!

For a super simple and healthy dinner, these sheet pan skirt steak fajitas are full of flavor with minimal effort!



  • 2 Tbsp. olive oil
  • 2 Tbsp. coconut aminos (or soy sauce)
  • Zest of 1 lime
  • Juice of 1 lime
  • 2 cloves of garlic, minced
  • 1 tsp. brown sugar
  • Salt and pepper
  • 1 skirt steak (about 1 lb.)
  • 2 - 3 bell peppers, sliced
  • 2 medium onions, sliced
  • In a small bowl, whisk the olive oil, coconut aminos, lime zest, lime juice, garlic, and brown sugar. Pour into a Ziploc bag. Add the steak, seal, and shake. Refrigerate for 30 minutes up to 2 hours.
  • Set the oven to high broil. Remove steak from the marinade. Then, season each side of the steak with salt and pepper. Broil for 4 minutes, then flip and broil for 2-3 minutes. Remove steak from the sheet pan and allow to rest.
  • Set the oven to 425 degrees. Add the veggies to the Ziploc bag or pour leftover marinade over the veggies. Season with salt and pepper. On the same sheet pan, spread the peppers and onions into a single layer. Roast for 25 minutes, until beginning to brown. Slice the steak. If you prefer steak that is more well-done, add sliced steak back to the sheet pan with the veggies for the last few minutes of roasting.
