Sheet Pan Chicken Fajitas
Ingredients
Method
- Preheat the oven to 425°F (220°C) and lightly grease a large sheet pan.
- In a small bowl, mix together the chili powder, smoked paprika, cumin, garlic powder, onion powder, oregano, cayenne, salt, and black pepper.
- Place the sliced chicken, peppers, and onion into a large mixing bowl.
- Drizzle with olive oil and lime juice.
- Sprinkle the seasoning mixture over everything and toss until evenly coated.
- Spread the chicken and vegetables into a single layer on the prepared sheet pan.
- Roast for 20 to 25 minutes, stirring halfway through, until the chicken is fully cooked and the vegetables are tender with lightly charred edges.
- For extra browning, broil for 2 to 3 minutes at the end.
- Serve immediately in warm tortillas with your favorite toppings.
Notes
- Slice the chicken and vegetables into similar-sized strips so they cook evenly.
- Don’t overcrowd the pan or the ingredients will steam instead of roast.
- Use a large sheet pan for the best caramelization.
- Chicken is done when it reaches an internal temperature of 165°F (74°C).

FAQs
Can I make Sheet Pan Chicken Fajitas ahead of time?
Yes. You can slice the chicken and vegetables up to one day in advance and store them separately in the refrigerator. Season everything just before baking for the freshest flavor.
Can I use chicken thighs instead of chicken breasts?
Absolutely. Boneless, skinless chicken thighs stay extra juicy and work perfectly in this recipe. Cooking time is about the same.
Why are my vegetables soggy?
The pan was likely overcrowded. Spread everything into a single layer with some space between the ingredients so they roast instead of steam.
Can I freeze the leftovers?
Yes. Allow everything to cool completely before freezing in airtight containers for up to 3 months. Thaw overnight before reheating.
What tortillas are best?
Both flour and corn tortillas work well. Flour tortillas are softer and more traditional for fajitas, while corn tortillas offer a slightly firmer texture and are naturally gluten-free.
Can I cook these on the grill?
Yes. Place the seasoned chicken and vegetables in a grill basket or on a griddle over medium-high heat until the chicken is cooked through and the vegetables are lightly charred.
Conclusion
Sheet Pan Chicken Fajitas are an easy one-pan dinner that delivers bold Tex-Mex flavor with very little effort. Juicy chicken, roasted peppers, and onions come together in under 40 minutes, making this a perfect weeknight meal that’s just as great for meal prep.
