Ingredients
- 1 lb boneless, skinless chicken breasts, thinly sliced
- 3 bell peppers (red, yellow, and green), sliced into strips
- 1 large yellow onion, thinly sliced
- 2 tablespoons olive oil
- 2 tablespoons fajita seasoning (blend of chili powder, cumin, smoked paprika, garlic powder, and salt)
Step-by-Step Guide to Perfectly Roasted Chicken and Veggies
- Preheat your oven to 425°F (220°C). This high heat will give your chicken and veggies a beautiful caramelized edge.
- In a large bowl, drizzle the olive oil over the sliced chicken, bell peppers, and onion. Toss together until all pieces glisten evenly.
- Sprinkle the fajita seasoning over the mixture. Toss well to coat every piece in that bold, smoky blend. For an extra hit of flavor, marinate for 10-15 minutes if time permits.
- Spread everything evenly across a large sheet pan in a single layer, ensuring the chicken and vegetables aren’t overcrowded for optimal roasting.
- Roast in the oven for 20-25 minutes, stirring or flipping halfway through. Look for golden, slightly charred edges and cooked-through chicken with an internal temp of 165°F (74°C).
- Once roasted, give a quick taste and adjust seasoning if necessary-sometimes a pinch of salt or extra squeeze of lime brightens the dish beautifully.
Tips for Customizing Your Fajitas to Suit Every Palate
By mastering these 5-Ingredient Sheet Pan Chicken Fajitas, you have a versatile base to experiment with flavor variations. Swap chicken for thinly sliced steak, shrimp, or tofu to keep everyone satisfied. Add a sprinkle of fresh chopped cilantro or a squeeze of lime for enhanced brightness. For heat lovers, add sliced jalapeños before roasting or serve with a smoky chipotle salsa.
Vegetable swap ideas include zucchini, mushrooms, or cherry tomatoes, which all roast beautifully alongside the classic peppers and onions. Feel free to increase seasoning quantities for a spicier bite or incorporate a dash of smoked sea salt for deeper flavor complexity.
Serving Suggestions and Easy Sides to Complete Your Feast
Accompany your fajitas with warm, soft flour or corn tortillas-wrapped around the juicy chicken and roasted veggies for the classic experience. For garnish, offer toppings like sliced avocados, tangy sour cream, shredded cheese, and fresh lime wedges for that final pop of zest. This recipe shines with simple sides such as Mexican rice, refried beans, or a crisp green salad sprinkled with cotija cheese.
If you want an easy, no-fuss side, serve with a chilled cucumber and tomato salad dressed lightly in lime juice and olive oil for refreshing contrast.

Chef’s Notes: Tips for Success
- Even slicing matters: Consistent sizes ensure uniform cooking and beautiful presentation.
- Don’t overcrowd the pan: Spacing allows veggies and chicken to roast instead of steam, locking in those savory charred flavors.
- Make-ahead option: Prep veggies and chicken with seasoning up to 12 hours ahead, store covered in fridge, then roast fresh when ready.
- Leftovers taste amazing: Reheat gently in a skillet over low heat to keep chicken tender and veggies crisp.
