Step-by-Step Instructions

  1. Preheat your oven: Set to 425°F (220°C) with a sturdy rimmed sheet pan inside to heat up. A preheated pan encourages caramelization and prevents sticking.
  2. Prepare the vegetables and chicken: Slice chicken, peppers, and onions into even strips for consistent cooking.
  3. Mix your fajita seasoning: In a small bowl, combine chili powder, cumin, paprika, onion powder, garlic powder, crushed red pepper, salt, pepper, and sugar.
  4. Toss everything together: In a large mixing bowl, add chicken strips, peppers, and onions. Drizzle with olive oil, sprinkle with the seasoning blend, and toss to coat thoroughly.
  5. Spread on the hot sheet pan: Carefully remove the hot sheet pan from the oven. Spread the chicken and veggie mixture in a single layer.
  6. Roast: Return the pan to the oven and roast for 20-25 minutes, stirring halfway through, until the chicken is just cooked and veggies are caramelized on the edges.
  7. Finish with lime: Squeeze fresh lime juice over the hot fajitas before serving.
  8. Serve: Pile the chicken and vegetables onto warm tortillas and top with your favorite garnishes.

  • Vegetarian Option: Replace chicken with portobello mushrooms, tofu, or extra veggies.
  • Spice Adjustment: Scale up or down the chili powder and red pepper flakes to control heat level.
  • Add Extra Veggies: Try zucchini, poblano peppers, cherry tomatoes, or corn for variety.
  • Sharp Slicing: Even slicing ensures even cooking—use a sharp chef’s knife.
  • Servings and Meal Prep: Double the recipe for crowds or future lunches; leftovers reheat beautifully.

Expert Tips for Perfect Sheet Pan Fajitas

  • Don’t crowd the pan: Spread ingredients out in a single layer to ensure roasting (not steaming).
  • Preheat the pan: A hot pan helps the chicken and vegetables caramelize quickly and evenly.
  • Rest before serving: Let the fajita filling sit for a couple of minutes out of the oven to keep juices in.
  • Warm your tortillas: Wrap them in foil and heat briefly in the oven, or on a dry skillet, for soft, pliable results.
  • Personalize your toppings: Set up a toppings bar so everyone can customize their fajitas.

Frequently Asked Questions (FAQs)

Q: Can I use frozen peppers or onions if I don’t have fresh?

A: Yes, but for best texture, thaw and pat dry before adding to the pan as frozen vegetables release more liquid and may not caramelize as nicely.

Q: Can this recipe be made ahead?

A: Absolutely. Prepare everything up to the point of baking, refrigerate covered for up to 6 hours, then roast just before serving. Leftovers also keep well for meal prep.

Q: How do I make this recipe lower in carbs?

A: Serve the fajita filling over salad greens, in lettuce wraps, or with cauliflower rice instead of traditional tortillas.

Q: Is this recipe spicy?

A: The recipe has mild to medium spice. Adjust the amount of chili powder and crushed red pepper to taste for your preferred heat level.

Q: What’s the best way to reheat leftovers?

A: For best results, reheat fajita filling in a skillet over medium heat, stirring occasionally. This helps maintain texture better than microwaving.
