How to Make Beef Fajitas in the Oven

Detailed instructions and measurements to make Sheet Pan Steak Fajitas are listed in the recipe card at the bottom of this page.

  1. Preheat the oven to 425ºF.
  2. Lightly spray the skirt steak with avocado oil spray and generously coat it in fajita seasoning. Repeat for both sides.
  3. Spray a heavy bottomed skillet with avocado oil spray and heat over medium-high heat. Add the skirt steak and sear quickly on both sides. Don’t cook it through, you’re only looking to sear it.
  4. Add the skirt steak to a sheet pan along with the onion, poblano, and bell peppers.

  6. Place the baking sheet in the oven for 15-20 minutes depending on how well done you would like your skirt steak.

Tips, Tricks, and FAQs for Oven Fajitas

  • Try to slice your vegetables in equal sizes to ensure even cooking.
  • Searing your steak will give it an excellent flavor. You can technically skip this step, but I highly recommend it.
How long should I cook beef fajitas in the oven?

I recommend cooking them for 15-20 minutes. The full length of time will depend on how you’d like your skirt steak cooked.

Should I line the sheet pan?

While lining the sheet pan is not required, using parchment paper will help with clean up.

Can I use different vegetables?

Yes, you can use whatever vegetables are your favorite. You’ll need to keep cooking time in mind if you change them out.

What cut of steak is used for fajitas?

I recommend using either flank or skirt steak when making beef fajitas.

How do I get my Fajita Meat Tender?

It’s important to not overcook the fajita meat in order to keep it tender.

What kind of sheet pan is best for Sheet Pan Steak Fajitas?

It’s best to use a sheet pan with rimmed edges to keep any liquid from spilling out into the oven.

Toppings for Fajitas

Some great toppings for fajitas include:

  • Sour cream
  • Cheese
  • Guacamole
  • Pico de Gallo

substitutions and alterations

  • skirt steak – While I feel that skirt steak will give you the best results, you can also use flank steak. It won’t be as tender and may not absorb as much flavor, but it will still taste great.
  • bell peppers – I use a variety of colors, but all colors work well.
  • poblano pepper – If you’re worried about spice or don’t like poblanos, you can omit this entirely.
  • onion – white onion lends the best flavor to this recipe, but red will work as well.
  • fajita seasoning I like using homemade, but you can use store bought or even use taco seasoning in a pinch.
  • avocado oil spray – I recommend avocado oil because of the high smoke point, but feel free to substitute olive oil if you prefer.

What To Serve With Oven Baked Fajitas

How to Store and Reheat Sheet Pan Steak Fajitas

To store the leftover fajitas, I recommend waiting until they cool completely and then placing them in an airtight container in the refrigerator up to 3 days.

To reheat them, I recommend reheating them in a skillet on the stove top. This will prevent your beef from becoming overcooked and you end up with a much better result.

If you reheat them in the microwave, you run the risk of overcooking your beef. I recommend if you do decide to take this route, reheating them 30 seconds at a time on medium heat.
