Easy Sheet Pan Fajitas

We’ve made these fajitas at least 7 times over the past few months. I think it’s safe to say they’re a favorite.

Not going to lie – They take a little extra prep work (meaning you’ve gotta slice up peppers, onions, and chicken) but other than that, they’re a breeze!

A few things I love about these sheet pan fajitas is everything is cooked on the same sheet pan so all the flavors blend together. It is pretty healthy with all the veggies and protein. You don’t have to babysit it at the stove. And you have fewer dishes to do after dinner!!

How to Make Chicken Fajitas

MARINATE. You can marinate the chicken overnight in a liquid marinade but I prefer to use a dry rub because I usually forget to marinate my chicken in advance, plus dry rubs work better than liquid marinades! We want the moisture from the chicken to evaporate quickly so it will sear well and create a delicious caramelized crust.

PREP. While doing all your prep work, preheat your oven to 400 degrees and place your baking sheet in the oven so it is nice and hot! Begin by chopping the bell peppers, onions and chicken. For cutting raw chicken, use a sharp knife that is not serrated. Make a clean cut rather than a sawing motion.With peppers and onions, cut them in long strips.

ROAST. Place your bell peppers and onions on the sheet pan. Spread them out evenly across the pan and roast them for 8 minutes. (Tip: Warming the pan before adding the veggies gives you less of a risk that the veggies stick and burn on the pan.)

While the veggies are roasting, mix the chicken and seasonings (dry rub). You can use the store-bought version if you are looking for a short cut!  

Add the chicken to the pan (making sure to separate the pieces of chicken so they don’t stick together) and bake for another 15-20 minutes or until the veggies are roasted and the fajitas are golden brown! 

After it comes out of the oven squeeze some lime juice over top (add a touch of freshly chopped cilantro) and it’s ready to be devoured- and trust me it will!

SERVE. I like to put my fajitas in a flour tortilla, but you can use corn or omit the tortilla altogether if you are trying to eat keto/low carb! Then I like to top it with cheese, sour cream, salsa and lettuce

Recipe FAQs

How to control the spice level? If you are concerned about the spice level you can decrease the amount of chili powder and chili flakes. This might be something to consider if you’re making it for kiddos.

Can you put whole pieces of chicken on the pan? If you choose to not cut the raw chicken just make sure to cook until the chicken is cooked through. Use a meat thermometer to ensure that it reaches 165 degrees.

Crockpot Instructions: Cover the bottom of the pot with a can of diced tomatoes and then the boneless chicken breasts and then the sliced veggies. Cook on high for 2.5-3 hours or on low for 4-6 hours then you can cut or shred the chicken. Just cook until the chicken is done and the veggies are tender. This is a great option but you will miss out on the caramelized texture of the chicken and roasted flavor of the veggies!

Instant Pot Instructions: Toss the chicken in the dry rub and then place the chicken strips on the stainless steel insert in the instant pot with a little oil on the bottom. Top with sliced peppers and add a ½ cup of water. Then set to manual high pressure for 10 minutes and after that quick release the pressure.

How to Store + Make Ahead

Sheet pan chicken fajitas are definitely best fresh, but you can do some of the prep work ahead of time! You can chop the veggies and chicken, the night before or the morning of, and store them in separate containers in the fridge. Or you can even chop them and freeze them for a future meal, just thaw it in the fridge the night before!

If you have leftovers, store them in an airtight container in the refrigerator for up to 4 days. Reheat either in the microwave or in a pan on the stovetop!

Ingredients

  • 3 tbsp vegetable oil - OR grapeseed/avocado oil, divided**
  • 3 bell peppers - seeds removed, ¼-inch thick slices
  • 1 yellow onion - thinly sliced
  • 1-1 1/2 lb chicken breasts - ¼-inch thick slices*
  • 2 tsp chili powder
  • 1 tsp cumin
  • 1 tsp garlic powder
  • 1 tsp kosher sea salt
  • 1/2 tsp ground black pepper
  • 1/2 tsp paprika
  • 1/2 tsp coriander
  • 1/8 tsp chili flakes - or cayenne pepper(optional)
  • 1 lime

Instructions

  • Preheat oven to 400 degrees. Place a standard size rimmed baking sheet in the oven while it heats so that it's nice and hot.
  • In large bowl toss 1 tablespoon oil with the bell peppers and onions. Carefully remove the hot baking sheet from the oven and spread the peppers and onions evenly across the sheet. Place in the oven and bake for 8 minutes.
  • Meanwhile, in the same bowl, combine the remaining oil along with the chicken, chili powder, cumin, garlic powder, salt, black pepper, paprika, coriander and chili flakes.
  • Remove the sheet from the oven, drain off any excess liquid and add the chicken, making sure to separate the pieces of chicken from each other (that way they don't bake together.
  • Return to the oven and bake for 15-20 minutes or until the vegetables are roasted and the fajitas are golden brown. Remove, squeeze the lime juice over top and serve with desired toppings.

Notes

*I prefer cutting the chicken against the grain. I find that this method creates more tender strips of fajita meat.
**Do NOT use olive oil!! We are roasting at a very high temperature. Olive oil should not be used at 400 degrees. I've used all three types of oil, however, vegetable and avocado are my favorite.
