Ingredients

For the Zesty Cilantro-Lime Marinade

  • 3 tbsp extra-virgin olive oil
  • Juice of 2 fresh limes (about 3 tbsp)
  • 1 tbsp lime zest
  • 4 cloves garlic, finely minced
  • 1.5 tsp ground cumin
  • 1.5 tsp chili powder
  • 1 tsp smoked paprika
  • 1/2 tsp dried Mexican oregano
  • 1/2 tsp sea salt and freshly ground black pepper
  • 1/4 tsp crushed red pepper flakes (optional for gentle heat)

For the Chicken and Sliced Vegetables

  • 1.5 lbs boneless skinless chicken breasts, sliced into 1/2-inch strips
  • 3 large bell peppers (1 red, 1 yellow, 1 green), sliced into 1/2-inch strips
  • 1 large red onion, sliced into 1/2-inch wedges
  • 1/4 cup fresh cilantro leaves, coarsely chopped

For Serving and Accompaniments

  • 8 small warm corn or whole-grain tortillas
  • 1 ripe avocado, diced or mashed with lime and sea salt
  • 1/2 cup fresh pico de gallo or salsa verde
  • 1/3 cup plain Greek yogurt (optional cooling crema)

Step-by-Step Instructions

1

Whisk the Marinade

In a medium mixing bowl, whisk together the olive oil, lime juice, lime zest, minced garlic, cumin, chili powder, smoked paprika, oregano, salt, black pepper, and red pepper flakes.

2

Marinate Chicken and Veggies

Place sliced chicken breast, bell peppers, and red onions into a large bowl (or two separate bowls if you prefer to arrange them separately on the pan). Pour the marinade over everything and toss thoroughly to coat. Let marinate for 15-20 minutes at room temperature (or up to 4 hours refrigerated).

Chef's Tip: Avoid marinating chicken in lime juice longer than 4 hours, as citrus acid can change the meat texture.
3

Arrange on a Preheated Sheet Pan

Preheat oven to 425°F (220°C). Lightly oil a large rimmed baking sheet (or line with parchment paper). Spread the chicken strips, peppers, and onions in a single even layer across the sheet pan, making sure ingredients are not piled on top of each other.

Chef's Tip: Spreading items out ensures roasting and browning rather than steaming.
4

Roast to Juicy Caramelization

Bake for 16-18 minutes until chicken is cooked through (internal temp 165°F / 74°C) and peppers are tender with lightly browned edges. For extra char, switch oven to BROIL for the final 2 minutes, watching closely.

5

Garnish and Assemble

Remove from oven, squeeze fresh lime juice over the pan, and sprinkle with fresh chopped cilantro. Serve hot with warm tortillas, fresh salsa, diced avocado, and Greek yogurt crema.

FAQ & Clarifications

Sheet-Pan Sizzling Chicken Fajitas with Cilantro Lime Marinade: FAQs

Evidence-aware answers to common questions about this topic.

Preheat your oven fully to 425°F (220°C) and do not crowd the pan. If your baking sheet is too small, use two separate sheet pans so moisture can evaporate freely, allowing the chicken and peppers to roast and caramelize.
