This easy juicy sheet pan fajitas recipe delivers tender, flavorful chicken or beef with caramelized peppers and onions, perfect for quick weeknight dinners or meal prep.

Ingredients

Scale
  • 1.5 lbs boneless, skinless chicken breasts or chicken thighs, thinly sliced (thighs give more juiciness)
  • OR 1.5 lbs flank steak or sirloin, thinly sliced against the grain
  • 2 large bell peppers (red, yellow, or green), thinly sliced
  • 1 large yellow or white onion, thinly sliced
  • 2 tsp chili powder
  • 1 tsp smoked paprika
  • 1 tsp ground cumin
  • 1/2 tsp garlic powder
  • 1/2 tsp onion powder
  • 1/4 tsp cayenne pepper (adjust to taste)
  • 1 tsp kosher salt
  • 1/2 tsp freshly ground black pepper
  • 3 tbsp olive oil, divided
  • Juice of 1 lime
  • 2 cloves garlic, minced
  • Optional: fresh cilantro, chopped for garnish

Instructions

  1. Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper if desired for easier cleanup.
  2. Slice your protein and veggies thinly, about 1/4-inch thickness. Slice beef against the grain.
  3. In a small bowl, whisk together chili powder, smoked paprika, cumin, garlic powder, onion powder, cayenne, salt, and pepper.
  4. In a large bowl, combine sliced chicken or beef with 2 tablespoons olive oil, lime juice, minced garlic, and half of the fajita seasoning. Toss well and marinate for at least 10 minutes (up to 1 hour in the fridge).
  5. In another bowl, toss sliced peppers and onions with remaining 1 tablespoon olive oil and remaining fajita seasoning.
  6. Arrange the marinated meat in a single layer on one side of the sheet pan and the veggies on the other side, avoiding overcrowding.
  7. Roast for 18-22 minutes, stirring or flipping halfway through for even cooking. Meat should be cooked through and juicy; veggies tender with slight caramelization.
  8. Remove from oven, sprinkle with fresh cilantro if desired, and squeeze extra lime juice over the top.
  9. Serve immediately in warm tortillas with your favorite toppings such as sour cream, guacamole, and salsa.

Notes

Slice meat and vegetables thinly for even cooking and juiciness. Marinate meat for at least 10 minutes to enhance flavor and tenderness. Use high heat (425°F) for caramelization. Avoid overcrowding the pan to prevent steaming. Let meat rest briefly after cooking. Use parchment paper for easier cleanup. Leftovers store well in fridge for 3 days or freeze up to 3 months.
