Ingredients You’ll Need for Sheet Pan Steak Fajitas
To make the best sheet pan steak fajitas, you only need a handful of fresh ingredients and pantry staples.
For the Fajitas:
- 1 ½ pounds flank steak or skirt steak (sliced thin against the grain)
- 3 bell peppers (use a mix of red, yellow, and green for color)
- 1 large red onion, sliced into thin strips
- 2 tablespoons olive oil
- Salt and pepper, to taste
For the Marinade:
- 3 tablespoons olive oil
- 2 tablespoons lime juice (fresh squeezed)
- 2 cloves garlic, minced
- 1 ½ teaspoons chili powder
- 1 teaspoon smoked paprika
- 1 teaspoon cumin
- ½ teaspoon oregano
- ½ teaspoon onion powder

For Serving:

How to Make Sheet Pan Steak Fajitas
This easy fajita recipe comes together in just a few simple steps. Let’s go through them one by one.
Step 1: Prepare the Marinade
In a medium bowl, whisk together olive oil, lime juice, garlic, and all the spices. This bold marinade infuses the steak with smoky, zesty Mexican-inspired flavors.
Step 2: Marinate the Steak
Place your sliced steak in a large resealable bag or bowl. Pour in the marinade, toss to coat, and refrigerate for at least 30 minutes (or up to 8 hours for deeper flavor).
Pro Tip: If you’re short on time, even a 15-minute quick marinade helps boost the flavor.
Step 3: Preheat and Prep the Pan
Preheat your oven to 425°F (220°C). Line a large sheet pan with foil or parchment paper for easy cleanup.
Spread the sliced bell peppers and onions evenly on the pan. Drizzle with olive oil, season lightly with salt and pepper, and toss to coat.
Step 4: Add the Steak
Remove the marinated steak from the fridge and arrange it on top of the veggies in a single layer.
Be sure not to overcrowd the pan—everything should roast evenly.
Step 5: Roast in the Oven
Bake for 15–20 minutes, or until the steak reaches your desired doneness and the vegetables are tender and slightly caramelized.
For extra flavor and char, you can broil for 2–3 minutes at the end of cooking.
Step 6: Rest and Serve
Remove the sheet pan from the oven and let the steak rest for 5 minutes. This helps lock in the juices.
Serve your sheet pan steak fajitas hot with warm tortillas and your favorite toppings. Don’t forget a squeeze of fresh lime juice for that final burst of flavor.
Tips for Perfect Sheet Pan Fajitas
- Slice against the grain: This ensures tender steak that’s easy to chew.
- Use high heat: Roasting at 425°F helps caramelize the veggies and sear the steak quickly.
- Don’t skip the lime juice: It balances the spices and brightens the dish.
- Prep ahead: Slice veggies and marinate the steak the night before for a 10-minute dinner.
- Add extra heat: Include jalapeño slices or chili flakes for a spicier kick.
What Kind of Steak Works Best?
The key to great fajitas is using a cut that’s flavorful and tender when cooked quickly. The top choices are:
- Flank steak: Lean, flavorful, and cooks beautifully on a sheet pan.
- Skirt steak: Classic for fajitas with rich, beefy flavor.
- Sirloin steak: Slightly thicker but still works well when sliced thin.
Whichever cut you choose, always slice against the grain after cooking for the best texture.
