Enjoy a delicious and easy dinner with this one pan sheet pan steak fajitas recipe. Simply toss all the ingredients onto a baking sheet, bake, and enjoy a flavorful meal in no time!
Stir together the seasonings in a small bowl and set aside.
Place the flank steak in a large bowl or ziplock bag, and add the 3 tablespoons oil, lime juice, and lime zest. Add 2 tablespoons of the seasoning as well, and toss everything to combine and coat the beef. Marinate in the fridge for 4-8 hours or overnight in the refrigerator. Reserve the remaining seasoning (there should be about 4 teaspoons left over).
Preheat the oven to 400°F and spray a large baking sheet with cooking spray.
Arrange the marinated beef and vegetables in a single layer on the baking sheet. Drizzle the remaining 1 tablespoon oil over the vegetables and sprinkle them with the remaining seasoning. Bake the sheet pan dinner for 12-14 minutes (12 for medium-rare, 13 for medium, 14 for medium-well), broiling for the last 1-2 minutes.
Remove the sheet pan from the oven and transfer the meat to a cutting board. Cover with aluminum foil for 10 minutes. After rest time, slice the steak, then serve the fajitas with warmed tortillas and toppings!
Notes
Marinating the beef is not required but does yield more tender and flavorful beef!
Leftovers keep in the fridge for up to 3 days.
Feel free to use store-bought fajita seasoning in place of the homemade version!
At 400°F, the beef goes from medium-rare to medium-well very quickly, especially after broiling. So keep an eye on it! We wouldn't skip the broiling step, though—it adds tons of flavor and gets you that classic charred fajitas look!
