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

Step-by-Step Instructions
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.
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).
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.
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.
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
Frequently Asked Questions
How do I prevent sheet-pan fajitas from becoming watery?
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.
Can I make this on an outdoor grill or cast-iron skillet instead?
Yes. For a skillet, cook over high heat in two batches for 8-10 minutes. For grilling, use a perforated grill basket for the vegetables and grill chicken breasts whole for 6 minutes per side before slicing.
Is this recipe good for healthy meal prepping?
It is one of the best meal prep recipes. Divide the cooked fajita meat and roasted vegetables into four glass meal prep containers with brown rice, black beans, and lime wedges for a ready-to-heat lunch throughout the workweek.
What makes this chicken fajita recipe healthier than takeout?
Takeout fajitas are frequently cooked in excessive commercial vegetable oils and high-sodium marinades. This recipe uses pure cold-pressed olive oil, fresh citrus, heart-healthy antioxidant spices, and delivers over 36g of protein with minimal sodium.
