These super easy steak sheet pan fajitas are one of my go-to weeknight recipes. It’s healthy and fast, and everyone in the family loves it.

Plus, you only have to clean up one pan! Well… maybe not you. I think it’s only fair that if you cook, they clean, am I right? This is the easiest meal, no matter which way you slice it.

What You’ll Love About This Recipe

  • Healthy. For sheet pan fajitas, steak is my favorite. Harvard Health suggests a moderate amount of saturated fat is A-Ok, and steak is rich in protein and iron.
  • Full serving of veggies. I like to cook up at least twice as many veggies to balance the meat but keep all the flavor. Add healthy fats from a side of guac, and you have a well-rounded meal.
  • Easy. Sheet pan steak fajitas are easy to make and even easier to clean up. No splatter, no frying pans… just chop, wait, and chow down.
  • Fast. Only 10 minutes of prep time. Better yet, these easy steak fajitas cook up in less than 15 minutes. Who’s hungry?

Recipe Notes

You can make this recipe with any protein that you like. I’ve personally made it with chicken, steak, and shrimp. They are all amazingly flavorful and super easy.

Ingredients you’ll need for steak fajitas

  • Protein. One to two pounds of chicken, steak, or shrimp.
  • Veggies. Bell peppers and red onions.
  • Spices. You’ll need a good taco seasoning blend. I make mine from scratch with chili powder, cumin, oregano, garlic, onion, coriander, paprika, and cayenne pepper.

Let’s Get Cooking

Step 1 — Cut the peppers and onions into strips. Set aside.

Step 2 — Slice the steak into strips.

I like to use a nice flank steak or strip steak, but you can use any cut of meat you like. My personal favorite is skirt steak.

One way to tenderize meat naturally is to marinate it in lime juice for at least 30 minutes in a small bowl. The acid in the lime juice does double duty for tenderness and flavor!

Step 3 — Season.

I usually add the veggies and the onions right to the sheet pan. Sprinkle with a little taco seasoning and your favorite oil. Olive oil works great here, but I love avocado oil in this recipe. The flavors combine beautifully, and avocado oil has a much higher smoke point than other oils.

I toss it all together with my hands and then spread the fajitas on the sheet pan in a single layer before popping it in the oven.

Clean-up is a breeze. You can also line your pan with parchment paper or aluminum foil for even quicker cleanup. Did I mention this meal just seriously couldn’t be easier?

Step 4 — Cook.

Preheat the oven to 425℉/220℃. Bake for 25 minutes total.

Bake the veggies for 10 to 15 minutes.

Add the steak to the sheet pan.

Return the sheet pan to the oven to bake another 10 minutes.

When I make steak or shrimp fajitas, I add the steak or shrimp after I’ve let the veggies cook for 10 to 15 minutes. Steak and shrimp take less time to cook than chicken does.

If you like your steak more on the well-done side, you can add the steak right from the beginning.

Season with a squeeze of lime.

Pro tip: Microwaving limes for 15 seconds makes it easier to squeeze out lots of juice!

FAQs and Recipe Variations

Follow the directions below (and in the recipe card) for different proteins.

How to make shrimp fajitas:

Shrimp cooks very quickly, so I usually bake the veggies for 10 to 12 minutes, then add the shrimp and let it cook for the remainder of the time. Shrimp is ready when it is pink all the way through.

How to make sheet pan chicken fajitas:

Add the chicken and veggies to the sheet pan, season, and then bake for 25 minutes in an oven preheated to 425℉. The chicken and vegetables will have the same cooking times. Chicken is cooked when it reaches 165 degrees.

What to serve with sheet pan fajitas:

A few toppings. I love to serve fajitas with homemade fresh guacamole + pico de gallo. Sour cream and cilantro are also pretty much required. Fresh limes and hot sauce add a nice, bright shot of authentic flavor.

Flour or corn tortillas. I love corn tortillas. Cooking tortillas only takes a few minutes per side. If you’re watching your carbs, you can buy your favorite kind, make your flour tortillas, or even make keto tortillas.
