Sheet Pan Chicken Fajitas
Tender chicken, colorful bell peppers, and sweet onions roast together on one pan for an easy weeknight dinner.
Ingredients
- 1 lb boneless skinless chicken breast, sliced into 1/4-inch strips, about 450 g
- 3 bell peppers cored and sliced into 1/4-inch strips, mixed colors
- 1 large yellow onion sliced into 1/4-inch strips
- 1/4 cup avocado oil or other high-smoke-point oil 60 ml
- 1 tbsp fajita seasoning
- 1 tbsp fresh lime juice from about 1/2 lime
- 1 tbsp tomato paste
- 2 tbsp water
- 2 cloves garlic minced
- 3/4 tsp kosher salt
Instructions
- Position an oven rack in the upper third of the oven. Place a large, rimmed baking sheet on the rack and preheat the oven to 425°F (220°C).
- In a large bowl, whisk together the avocado oil, fajita seasoning, lime juice, tomato paste, water, minced garlic, and salt to create the marinade.
- Add the sliced chicken to the bowl and toss until it is well coated.
- Add the sliced bell peppers and onion to the bowl. Toss again until the vegetables and chicken are evenly coated.
- Carefully remove the hot baking sheet from the oven. Pour the chicken and vegetable mixture onto the pan and spread it into a single, even layer.
- Bake for 15 to 18 minutes, or until the chicken is cooked through and the vegetables are tender.
- For food safety, check that the chicken has reached an internal temperature of 165°F (74°C) on an instant-read thermometer.
- For extra char, you can switch the oven to broil and cook for 2 to 4 minutes, watching closely to prevent burning.
- Let the fajita mixture cool for a moment before serving warm with tortillas and your favorite toppings.
Notes
Food Safety: Always ensure chicken is fully cooked. The safest way to check is with a meat thermometer, which should read 165°F (74°C) in the thickest part of the chicken.
Hot Pan Tip: Preheating the sheet pan helps the ingredients sizzle on contact. This gives them a better texture and prevents them from steaming.
Avoid Crowding: Spreading the ingredients in a single layer is important for even roasting. If your pan seems too full, it's better to use two sheet pans.
