Make these Sheet Pan Steak Fajitas for a quick, flavorful weeknight meal. You cook juicy steak strips, peppers, and onions on one pan for simple prep and cleanup. This recipe delivers restaurant-style fajitas fast.

Ingredients

Scale
  • 1.5 lbs flank steak, sliced against the grain
  • 2 tablespoons olive oil
  • 1 tablespoon chili powder
  • 1 teaspoon cumin
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1 red bell pepper, sliced
  • 1 green bell pepper, sliced
  • 1 yellow onion, sliced
  • Optional: Tortillas, salsa, sour cream, or lime wedges for serving

Instructions

  1. Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper for easy cleanup.
  2. In a medium bowl, combine the chili powder, cumin, smoked paprika, garlic powder, onion powder, salt, and pepper.
  3. Add the sliced steak, bell peppers, and onion to the bowl. Drizzle with olive oil. Toss everything together until the steak and vegetables are evenly coated with the spice mixture.
  4. Spread the steak and vegetable mixture in a single layer on the prepared baking sheet. Do not overcrowd the pan; use two sheets if necessary to ensure proper roasting.
  5. Bake for 12 to 15 minutes, tossing halfway through, until the steak reaches your desired doneness and the vegetables are tender-crisp.
  6. Remove from the oven. Serve the steak fajitas immediately with warm tortillas and your favorite toppings.

Notes

  • For extra juicy steak fajitas, marinate the steak in the spice mixture and oil for at least 30 minutes before baking.
  • If you prefer a slow cooker steak fajitas method, combine all ingredients in the slow cooker and cook on low for 6-8 hours or high for 3-4 hours, then broil briefly if you want some char.
  • This recipe works well for healthy steak fajitas when served over rice or greens instead of tortillas, making a great steak fajita bowl.
