How to Make Sheet Pan Chicken Fajitas
Ingredients
- 1 lb (450 g) chicken breast, thinly sliced
- 1 large bell pepper (any color), thinly sliced
- 1 medium onion, thinly sliced
- 2 tablespoons olive oil
- 1 tablespoon chili powder
- 1 teaspoon ground cumin
- 1 teaspoon garlic powder
- Salt and freshly ground black pepper, to taste (start with 1/2 teaspoon salt and adjust)
- 8 small tortillas (corn or flour), for serving
- Optional toppings: sliced avocado, salsa, shredded cheese, sour cream, lime wedges, chopped cilantro
Substitutions and optional ingredients
- Use chicken thighs (boneless) for more fat and flavor — increase cook time slightly if thicker.
- Swap olive oil with avocado oil or a neutral oil.
- Add 1/2 teaspoon smoked paprika or a pinch of cayenne for smokier or spicier notes.
- For a lower-sodium version, omit added salt and use fresh lime and herbs to boost flavor.
Method (step-by-step)
- Preheat the oven to 400°F (200°C). Line a large sheet pan with parchment paper or foil for easy cleanup.
- In a large bowl, combine the sliced chicken, bell pepper, and onion.
- Drizzle with 2 tablespoons olive oil. Add 1 tablespoon chili powder, 1 teaspoon cumin, 1 teaspoon garlic powder, and salt and pepper.
- Toss until everything is evenly coated — use your hands or tongs and avoid overmixing, which can bruise the vegetables.
- Spread the mixture in an even layer on the prepared sheet pan. Leave a little space between pieces so they roast rather than steam.
- Bake for 18–22 minutes, tossing once halfway through, until the chicken reaches an internal temperature of 165°F (74°C) and the vegetables are tender with some caramelized edges.
- Remove from the oven and let rest 2–3 minutes. Squeeze lime over the top if using.
- Serve hot in warmed tortillas with your favorite toppings.
Practical tips
- Check doneness with a meat thermometer; thickness of slices affects cook time.
- If vegetables are cooking faster than chicken, push them to one side of the pan for the last 5 minutes.
- For extra char, broil for 1–2 minutes at the end while watching closely.

Best Pairings
- Side salads: A crisp cabbage slaw with lime and cilantro cleanses the palate.
- Rice or grain bowls: Serve fajita chicken over cilantro-lime rice or quinoa for a heartier meal.
- Beans: Black beans or refried beans make excellent, protein-rich sides.
- Drinks: Margaritas, light Mexican lagers, or iced tea — choose depending on occasion.
- Kid-friendly option: Serve deconstructed with rice and mild salsa for little ones.
Storage Instructions
- Room temperature: Do not leave cooked chicken out more than 2 hours (1 hour above 90°F). Per USDA food safety guidelines, bacteria can grow rapidly at room temperature.
- Refrigeration: Store in an airtight container for 3–4 days. Reheat gently in a skillet or oven to avoid drying out.
- Freezer: Freeze cooked chicken and veggies in a sealed freezer-safe container or heavy-duty zip-top bag for up to 3 months. Thaw overnight in the refrigerator before reheating.
Chef’s Advice
- Slice chicken thin and uniform: Thin, even slices cook quickly and evenly.
- Use high heat for good color: 400°F gives charred edges without overcooking the chicken.
- Don’t overcrowd the pan: Crowding traps steam and prevents browning. Use two pans if needed.
- Layer flavor: Add a squeeze of lime and fresh cilantro at the end to brighten roasted flavors.
- Reheating: Warm gently in a skillet over medium heat with a splash of water or broth to restore moisture.
Creative Twists
- Tex-Mex BBQ: Toss the chicken and veggies with 2 tablespoons BBQ sauce at the end, then finish under the broiler for glossy, smoky bites.
- Vegetarian/Vegan: Replace chicken with firm tofu or tempeh (press briefly), or use a combination of portobello mushrooms and chickpeas; adjust seasoning and cook time.
- Mediterranean Fajita Fusion: Swap spices for oregano and smoked paprika, add kalamata olives and feta as toppings, and serve in warm pita.
- Low-carb: Serve over cauliflower rice or wrapped in large lettuce leaves.
- Citrus-chili glaze: Mix orange juice, a splash of honey, and a pinch of chili powder; toss with the cooked fajitas for a bright-sweet finish.
Frequently Asked Questions
Q: Can I make this ahead of time?
A: Yes — cook and cool, then refrigerate up to 3 days. Reheat gently in a skillet or oven. For parties, you can roast the components ahead and crisp them briefly under the broiler before serving.
Q: Can I use frozen chicken?
A: Thaw fully in the refrigerator before slicing and seasoning so it cooks evenly. Cooking from frozen will yield uneven results.
Q: How do I make it spicier or milder?
A: For heat, add cayenne, fresh jalapeños, or chipotle powder. To mellow the spice, reduce the chili powder and balance with a touch of honey or more citrus.
Q: Are corn tortillas better than flour?
A: It’s about preference. Corn tortillas are gluten-free and have more texture; flour tortillas are softer and can be larger for heartier wraps.
Q: What if my vegetables get too soft?
A: Roast at a slightly higher temperature briefly or cut veggies thicker. Tossing halfway helps even cooking and prevents over-softening.
