Ingredients
Scale
- 1.5 pounds boneless, skinless chicken breasts, trimmed and sliced into strips
- 3 medium bell peppers (red, yellow, and green), sliced
- 1 large yellow onion, thinly sliced
- 2 tablespoons extra virgin olive oil
- 2 tablespoons fajita seasoning (homemade or store-bought)
- 2 cloves garlic, minced
- Juice of 1 lime
- Salt and pepper to taste
- Optional toppings: chopped cilantro, sliced avocado, sour cream, shredded cheese
Instructions
- Preheat your oven to 400°F (200°C). Line a rimmed baking sheet (about 18×13 inches) with parchment paper or lightly grease it.
- Slice the chicken breasts into roughly 1/2-inch strips, keeping them uniform for even cooking.
- Thinly slice the bell peppers and onion into strips similar in size to the chicken.
- In a large mixing bowl, combine the chicken strips, sliced peppers, and onions. Add olive oil, minced garlic, and fajita seasoning. Toss gently but thoroughly until all pieces are well-coated.
- Spread the mixture evenly across the sheet pan in a single layer, avoiding overcrowding.
- Roast in the preheated oven for 20-25 minutes. About halfway through, use tongs to flip the chicken and vegetables to ensure even cooking and caramelization.
- Check for doneness: chicken should reach an internal temperature of 165°F (74°C) and no longer look pink; peppers should be tender with slightly charred edges.
- Remove from oven and squeeze fresh lime juice over everything. Toss lightly to mix.
- Serve immediately with optional toppings like chopped cilantro, avocado slices, or sour cream.
Notes
Do not overcrowd the pan to avoid steaming the chicken. Use room temperature chicken for even cooking. Flip the chicken and vegetables once halfway through roasting for best caramelization. Let the chicken rest a few minutes before serving to keep it juicy. Fresh lime juice added after cooking brightens the flavors.
