Ingredients & substitutions

• Beef: The best cuts of beef for sheet-pan steak fajitas are flank or skirt steak. Both varieties soak up marinades and seasonings quite well and cook relatively fast.
• Bell pepper: I like to use brightly colored bell peppers, like red, orange, and yellow, to give the dish some vibrance. Feel free to use green or any color combination you prefer!
• Yellow onion: The natural sugars of the onion are brought out beautifully by cooking it down with bell peppers. A white or red onion will also work to create a similar flavor.
• Spices: For a rich, smoky, spicy, and savory blend that holds up to steak, I use chili powder, cumin, smoked paprika, oregano, garlic powder, onion powder, and cayenne powder. Play around with the ratios until it is just right for you!
• Salt: Enhances the flavors of the fajitas. Taste and adjust the salt to your liking.

• Olive oil: To cook the steak and vegetables, I recommend extra-virgin olive oil. You can also try other vegetable oils, like canola, sunflower, or safflower.
• Lime juice: I love a good squeeze of fresh lime juice on my steak fajitas. It adds acidity and the perfect amount of brightness. If you don’t have any limes, use lemons instead.
• Scallions: To finish the fajitas off and add more color. Cilantro also works here.
• Tortillas: You can use either flour or corn tortillas for sheet-pan steak fajitas. Whatever the case, just make sure they are nice and warm before serving.
• Toppings: This is where you can get really creative! Try mixing and matching toppings like sour cream, guacamole, salsa, pickled onions, or pickled jalapeños.

How to make sheet-pan steak fajitas

Step 1: Cut the steak and veggies and Make seasoning

Preheat the oven to 400F and line a pan with foil. In the meantime, slice the steak, onions, and bell peppers into thin strips. In a large bowl, combine the steak, bell pepper, and onion. In a separate bowl, whisk together the spices and salt.

Step 2: Season the fajitas

Toss the steak, peppers, and onions with the olive oil and fajita spice mixture until well-coated. Let the mixture marinate at room temperature for about 20 minutes to better infuse flavor.

Step 3: Bake the fajitas

Transfer the steak and vegetables to the prepared baking sheet in a single layer. Bake the fajitas for 10-12 minutes, or until the steak is cooked to your liking. Remember to stir the fajitas at the halfway point.

Just before serving, toss the mixture with lime juice and scallions. Serve your sheet-pan steak fajitas in warm tortillas with your choice of toppings and sides!

Serving suggestions

Sheet-pan steak fajitas go incredibly well with classic garnishes and side dishes like sour cream, guacamole, salsa, pickled onions, pinto beans, refried beans, Mexican grilled corn on the cob, pickled jalapeños, fresh cilantro, and more.

You can serve them in warm corn or flour tortillas, or add them to the top of Mexican rice or cilantro-lime rice to make fajita bowls.

For a delicious Mexican meal, serve along with another main dish like Blackened Chicken Enchiladas.

Recipe variations

• Vegetarian: Instead of beef, try portobello mushrooms for an equally rich and savory meat-free option.
• Low-carb: Replace corn or flour tortillas with lettuce wraps for a low-carb meal.
• Extra vegetables: Add veggies, like mushrooms, zucchini, and corn, for extra flavor and texture.

Tips and tricks

• Use a thermometer: To achieve your preferred doneness, use a meat thermometer to measure the internal temperature of the steak.
• Let the meat rest: Let the meat rest for at least 5-10 minutes before serving so the juices have time to redistribute.
• Slice against the grain: Cut against the fibers to keep the steak extra tender and juicy.

• Marinate the fajitas: Allow the steak and veggies to marinate for at least 20-30 minutes to absorb the flavors.
• Cut the veggies evenly: Slice the bell peppers and onions into similarly-sized strips for even cooking.
• Preheat: Don’t forget to preheat the oven to ensure an even cooking temperature.

What to do with leftovers

If you have leftover sheet-pan steak fajitas, here’s what to do:

• Fridge: Once completely cooled, store leftovers in an airtight container for up to 3 days.
• Freezer: Freeze leftovers in airtight containers or freezer-safe bags for up to 3 months.
• Reheating: Reheat the fajitas in a skillet over medium heat until warm. You can also heat them in the microwave in 30-second intervals, stirring in between.
• Prep ahead: You can slice the vegetables and prepare the toppings in advance to save time during cooking.
