Simple Sheet Pan Steak Fajitas

I love how versatile this recipe is. Switch up the protein, and you’ll end up with sheet pan chicken fajitas or shrimp fajitas. Or take out the protein altogether and add more veggies like red onion, zucchini, or mushrooms! If you’re trying to eat low-carb, you can cut out the tortilla and make lettuce wrap fajitas! You really can’t go wrong!

I love fajita seasoning! If you’re like me and love these flavors, you’ve got to try out my chicken fajita soup, grilled steak fajitas, and blackened shrimp fajitas. They are all packed with flavor and simple to make!

• Flank Steak: This is the main protein and gives the dish a hearty, meaty texture and rich beef flavor.
• Lime Juice: Adds acidity and helps marinate the meat. It also gives the dish a bright flavor.
• Olive Oil: Provides a base for the marinade and helps in the caramelization process.
• Fajita Seasoning: This combination of spices—paprika, garlic powder, chili powder, cumin, onion powder, and dried oregano—gives the dish a burst of flavor. You can make your own by following my fajita seasoning recipe!
• Yellow Onion: Provides a hearty flavor that compliments the steak.
• Red, Green, and Yellow Bell Peppers: These vegetables give the dish color, crunch, and delicious flavor.
• Salt & Pepper: To taste!

For Serving

• Small flour or corn tortillas: These provide the perfect shell to hold all of your meat and vegetable mixture and any toppings you desire!
• Limes: With a squeeze of lime juice, your fajitas will be next level!
• Cilantro: Fresh cilantro is not only a beautiful garnish, it adds that fresh herbal flavor that elevates any dish!
• Avocado (optional): I love using avocado to top my tacos, whether simply sliced or mixed into guacamole!

Sheet Pan Steak Fajitas Recipe

This recipe is very straightforward. Make your sauce, slice the meat, chop your veggies, and bake! Dinner is served!

1. Preheat: Preheat the oven to 400 degrees Fahrenheit and then line a baking sheet with foil. Prepare the steak by slicing it into ½ inch strips.
2. Whisk: In a bowl, whisk together two tablespoons of olive oil, 1 ½ tablespoons of fajita seasoning, and lime juice to make a marinade.
3. Marinate: Add the sliced steak and marinade to a bag and let it rest while you prepare the vegetables.
4. Slice and Toss: Slice the peppers and onion into ½-inch slices, then toss them in a bowl with the remaining olive oil, fajita seasoning, and salt and pepper.
5. Spread out on sheet pan: Lay the vegetables out on the foil-lined sheet pan, leaving room for the steak. Then, place the steak on the sheet pan next to the vegetables.
6. Bake: Bake the fajita mix for 12-15 minutes, but you will need to toss and turn the vegetables and steak halfway through baking.
7. Prep items for serving: While the fajita mix is baking, toast the flour tortillas and slice the limes and fresh cilantro.
8. Let rest: When the steak is cooked through, and the vegetables are tender, remove the pan from the oven and allow them to cool for a few minutes. Then, you can serve it with your favorite toppings!
