Ingredients

Scale
  • 1.5 pounds flank steak or skirt steak, trimmed and sliced thinly against the grain
  • 23 medium bell peppers (red, yellow, green), sliced into strips
  • 1 large yellow or white onion, thinly sliced into half-moons
  • 2 tablespoons olive oil, plus more if needed for roasting
  • 1 teaspoon chili powder
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon cumin
  • 1/2 teaspoon garlic powder
  • 1/4 teaspoon cayenne pepper (optional)
  • Salt and black pepper to taste
  • 1/2 cup sour cream or Greek yogurt
  • Juice of 1 lime
  • 1 garlic clove, minced or grated
  • Salt to taste (for lime crema)
  • A handful of fresh cilantro, chopped (optional, for garnish)
  • Flour or corn tortillas, warmed, for serving

Instructions

  1. In a medium bowl, combine olive oil, chili powder, smoked paprika, cumin, garlic powder, cayenne pepper (if using), salt, and black pepper. Add the sliced steak and toss to coat evenly. Let marinate for at least 10 minutes, up to 30 minutes if time allows.
  2. While the steak marinates, slice the bell peppers and onion into thin strips about 1/4 inch thick.
  3. Preheat oven to 425°F (220°C).
  4. Spread the marinated steak in a single layer on one half of a large rimmed sheet pan. Spread the peppers and onions on the other half. Drizzle a little more olive oil over the veggies and sprinkle with salt and pepper.
  5. Place the sheet pan in the oven and roast for 15-18 minutes. Halfway through (around 9 minutes), use tongs to flip the steak pieces and stir the vegetables for even cooking and browning.
  6. Check that the steak is browned on the edges and cooked to medium-rare or medium, depending on thickness. Vegetables should be tender with some charred spots.
  7. While roasting, whisk together sour cream or Greek yogurt, lime juice, minced garlic, and a pinch of salt in a small bowl to make the lime crema. Adjust lime or salt to taste.
  8. Remove the sheet pan from the oven and let the steak rest for a few minutes.
  9. Warm tortillas in a dry skillet or microwave.
  10. Assemble fajitas by placing steak and veggies on tortillas, topping with lime crema and chopped cilantro.

Notes

Do not overcrowd the sheet pan to ensure proper roasting and caramelization. Slice steak thinly against the grain for tenderness. Use fresh lime juice for the crema for best flavor. Marinate steak and prep vegetables ahead to save time. For dairy-free lime crema, substitute sour cream with coconut yogurt or avocado crema. Corn tortillas make this recipe gluten-free.
