Sheet pan dinners are some of my most favorite recipes. Mostly because they’re simple to throw together, especially on busy weeknights. These oven fajitas are no different. With some simple prep before-hand, these baked chicken fajitas go all on one sheet pan, and right into the oven.

Here’s the simple steps to making these Easy Sheet Pan Chicken Fajitas

Step 1: Start by prepping your ingredients

Here’s the ingredients you’ll need for these oven fajitas:

1 1/2 lbs. boneless, skinless chicken breasts
Green, yellow and red bell peppers (1 of each)
Red onion
Minced garlic (about 3 cloves)
Lime juice (juice of 2 limes
Olive oil
Spices: chili powder, cumin, smoked paprika, garlic salt and ground pepper.
For Serving: corn or flour tortillas, sour cream, avocado slices or guacamole, diced tomatoes or pico de gallo salsa, shredded cheese of your choice.

Step 2: Slice the peppers and onions and place on a Sheet Pan

Slice all of the peppers and onions in long strips. Lightly spray an 17 x 12″ sheet pan with non-stick coconut oil spray. Place the all of the sliced peppers and onions on to the pan.

Step 3: Add the sliced chicken, garlic, olive oil, lime juice and seasoning

On top of the peppers and onions you’ll add the chicken breast that has been sliced into long, thin strips. Add the minced garlic cloves. Top with the lime juice and olive oil.

In a small bowl, add the chili powder, cumin, smoked paprika, garlic salt and pepper. Stir together to combine. Sprinkle over the top of the ingredients on the pan.

Directly on the pan, toss all of the ingredients together to coat well. You can use a couple of spatulas or rubber scrapers, however, what worked best for me was using my hands.

Step 4: Place the fajita mixture into the oven to bake

Once all of the ingredients are coated, make sure they are all in an even layer on the pan. You’ll bake at 400 degrees for 18-25 minutes or until the chicken is cooked through.

To make sure everything cooks evenly, about 10 minutes into cooking, toss the ingredients to make sure everything is cooking evenly.

These baked chicken fajitas will come out of the oven smelling amazing! Serve right away while hot with some warm tortillas, and all of your favorite Tex-Mex toppings.

Frequently Asked Questions about Baked Chicken Fajitas:

How can I meal prep these sheet pan chicken fajitas?

To cut carbs, I like to enjoy these fajitas over cauliflower rice, as a Chicken fajita bowl. To your favorite meal prep container, add in a 1/2 cup of cauliflower rice, then a 1 1/2 cup serving of the chicken fajitas (Chicken, peppers & onions).

Top with all of your favorite toppings, like cherry tomatoes, cilantro, avocados, jalapeno peppers and a sprinkle of cheese.

What should I top these oven fajitas with?

Just like tacos, burritos and enchiladas, these oven fajitas are perfect with Classic Pico de Gallo Salsa, Loaded Guacamole, my Homemade Taco Sauce, Avocado Lime Ranch Dressing and my Black Bean Corn Salsa.

Other toppings include cilantro, shredded cheese, queso fresco, sliced jalapeno peppers, salsa, fresh limes (for lime juice) and guacamole or avocados.

How do you keep fajitas warm for a party?

You can do this a couple of ways:

First, you can put the chicken fajita filling in a crock pot or slow cooker on the lowest temperature setting to keep warm. Serve along side all of your toppings and sides (listed above).
The second way you can do this in keep the fajitas on the sheet pan in the oven, at at around 200 degrees. Keep the fajitas covered with foil to keep moisture in and prevent the chicken from drying out. Take out of the oven just before your ready to serve.

What type of tortillas are typically served with fajitas? Corn or Flour?

A medium-sized flour tortilla is typically the best choice for a fajita. Corn tortillas, although a healthier option, have a tendency to tear and rip when the meat, peppers and onions are added along with all the other toppings.
