This recipe is great for those following a low-carb diet. You can serve as is or with keto tortillas. It's also paleo-friendly, gluten-free, dairy-free, and Whole30 compliant! Our only recommendation? Say, "Yes, I'll take the guacamole, please." Because we all know that avocados are life, no matter what kind of dietary plan you're following.


Sheet Pan Chicken Fajitas Ingredients

Who wouldn't want to eat fajitas for lunch all week? Or dinner! Here's what you need:

  • 1 ½ pounds chicken breasts
  • 1 tablespoon olive oil
  • 1 tablespoon taco seasoning
  • 3 bell peppers, any color, sliced
  • 1 onion, sliced
  • Limes, for serving

How to Make Chicken Fajitas

This couldn't be easier. Slice everything up and toss it with taco seasoning and olive oil. Then, load it onto the sheet pan, which you've also greased with a little bit of oil, and bake for less than a half an hour. It's really that quick. Clean-up is a snap because you're basically only washing a knife, a cutting board and, once the meal is prepped or served, the sheet pan. Seriously.

Substitutions and Alterations

  • Feel free to use chicken thighs instead of chicken breasts.
  • Add fresh herbs at the end like chopped cilantro.
  • Use a red onion for something a little sweeter, or a Vidalia onion for the sweetest onion.
  • Kick up the heat and use a few shishito peppers if desired; not all of them are spicy but some are. It's an adventure!

How to Serve Sheet Pan Chicken Fajitas

Granted, we like this for a weeknight meal for all the aforementioned reasons. But there's no reason why you can't double or triple this (get more sheet pans, you'll need 'em!) recipe and serve it for a party. Put out all the fixins on the side so people can load up with the toppings they want, like sour cream, pico de gallo, cheddar and/or Monterey jack cheeses, chopped cilantro and, of course, guacamole. (Any kind of salsa would work, though, if you don't have pico. Skip the tortillas or opt for gluten-free or low-carb ones as needed. Or serve with regular rice or cauliflower rice.

How to Store Chicken Fajitas

Once they're prepped, this recipe will keep for up to 4 days in a sealed and airtight container in the fridge. Just reheat gently in the microwave or on the stovetop with a little bit of olive oil in the pan. You can also freeze these in an airtight zip-close plastic bag. Defrost overnight in the refrigerator and then reheat as directed. This kind of meal prep takes well to the freezer.

  1. Loved this recipe but I would like to know the macros for this meal, or at least the total calories at a bare minimum.

    1. Hi Andrew - We are so happy you enjoyed the recipe. Unfortunately, we did not calculate out the nutritional profile for this
      the recipe, however, you can easily add it to your food tracker such as MyFitnessPal to get the full nutrient breakdown based
      on the specific ingredients, you use.

  2. Why was the recipe changed to “taco seasoning” instead of the list of spices? It was our favorite combination of spices. Now I have to scoure the internet for a new combination and, so far, none of them quite do it for us. 😩
