Ingredients

  • 1 pound steak flank, sirloin, or skirt, sliced into thin strips
  • 1 red onion sliced
  • 1 red bell pepper sliced
  • 1 green bell pepper sliced
  • 1 yellow bell pepper sliced
  • 2 Tablespoons olive oil
  • 2 Tablespoons fajita seasoning
  • 6 cloves garlic minced

Instructions

  • Preheat Oven: Set your oven to 400°F (200°C).
  • Prepare Ingredients: Slice the steak, onion, and bell peppers into thin strips.
    1 pound steak, 1 red onion, 1 red bell pepper, 1 green bell pepper, 1 yellow bell pepper
  • Season & Coat: In a large bowl, toss the steak and vegetables with olive oil, fajita seasoning, and minced garlic. Mix well to coat evenly.
    2 Tablespoons olive oil, 2 Tablespoons fajita seasoning, 6 cloves garlic
  • Arrange on Sheet Pan: Spread everything out in a single layer on a large baking sheet.
  • Bake: Cook for 15-20 minutes, tossing halfway through, until the steak is cooked to your desired doneness and the vegetables are tender.
  • Serve: Enjoy with warm tortillas, fresh lime wedges, and your favorite toppings like sour cream, avocado, or cilantro.

Notes

Storage: Transfer leftovers to an airtight container, and store them in the refrigerator for up to 3 days. If possible, keep the proteins and veggies in a separate container from the tortillas. For longer storage, freeze the fajitas in a sealed container for up to 2 months. Reheat in the air fryer or a skillet to bring back the texture.
