Sheet Pan Fajitas Overview
This entire fajita mix is all prepped and baked in one single baking sheet. You don’t need to add a lot of extras to this meal.
You can add extra toppings if you want, like sliced avocado, fresh lime, cilantro, shredded lettuce, hot sauce, sour cream and guacamole. OR you can keep it super simple by just using the sheet pan fajitas as the filler with a little salsa – all rolled in a tortilla wrap or served over rice.

Recipe Tips

- Chicken slices tend to cook fast. Check the chicken using a meat thermometer so that you don’t overcook it.
- Serve this recipe with taco shells or over a bed of rice.
- You can add extra toppings if you want, like sliced avocado, fresh lime, cilantro, shredded lettuce, hot sauce, sour cream and guacamole.
How To Store Leftovers
Refrigerate – Let the recipe cool completely, then cover it with plastic wrap and chill in the fridge up to 3-4 days. The vegetables will naturally get a little soggier over time but can still be enjoyed.
