Ingredients

  • 2 lbs boneless skinless chicken breast cut in half horizontally and cut ½ inch slices (*see notes)
  • 3 medium peppers (poblanos or bell peppers) cut in ½ inch slices (**see note)
  • 1 medium yellow or sweet onion cut in ¼ inch slices
  • 3 tablespoon olive oil
  • 2 teaspoon kosher salt
  • ½ teaspoon pepper
  • 2 teaspoon chili powder
  • teaspoon cumin
  • teaspoon smoked paprika
  • 1 teaspoon garlic powder
  • teaspoon granulated sugar
  • 10-12 tortillas
  • Optional toppings: Salsa, sour cream, limes, lettuce, avocado, shredded cheese

Instructions

  • Preheat the oven to 425°F. I leave my sheet pan unlined, but feel free to line with foil if you want.
  • Place the sliced chicken, peppers, and onions in the middle of the sheet pan. Drizzle with olive oil and sprinkle evenly with seasonings. Toss well with tongs until evenly combined.
    2 lbs boneless skinless chicken breast, 3 medium peppers (poblanos or bell peppers), 1 medium yellow or sweet onion, 3 tablespoon olive oil, 2 teaspoon kosher salt, ½ teaspoon pepper, 2 teaspoon chili powder, 1½ teaspoon cumin, 1½ teaspoon smoked paprika, 1 teaspoon garlic powder, 1½ teaspoon granulated sugar
  • Spread everything into a single layer. Bake for 14-16 minutes, or until the chicken is cooked through and a thermometer registers 165°F. During the last 3-5 minutes, switch your oven setting to broil. Place the sheet pan on the highest rack and broil until veggies and chicken are charred on the edges.
  • Serve with warm tortillas and toppings of choice. Enjoy!

Notes

*Chicken: You can use boneless skinless chicken thighs instead. Do not cut them in half horizontally; just cut them into ½ inch slices.
**Peppers: We used 2 poblanos and 1 yellow bell pepper in the pictures, but you can use any combination you like. 
***We use an extra large baking sheet. You can use regular, but if it doesn't fit in a single layer you should use two pans. 
 
Tips and Tricks
  • An extra large baking sheet will cook the most evenly and roast beautifully.
  • There will be some juices on the pan after cooking (that's a normal part of sheet pan dinners). You can drain the juices before serving if you prefer.
  • Don't cook anything else in the oven at the same time. This will prevent steaming.
 
Storage and Reheating
  • Store in an airtight container in the fridge for 3-4 days.
  • Reheat in a hot cast iron skillet, in the microwave for 1-2 minutes, or under the broiler for 3-4 minutes until warmed through.
