What are Sheet Pan Chicken Fajitas?
Sheet pan chicken fajitas are a simple way of cooking a traditional Mexican Food favorite, with minimal fuss and minimal cleanup. No need to have hot oil splattered all over or multiple pans on the stove top. Instead, we’ll take a slightly different approach and lay out all the seasoned ingredients on a sheet pan (cookie sheet, baking sheet), and let it cook to perfection in the oven for around 20 minutes. When it’s done, it’s done. We take it out and serve it immediately on fresh tortillas with our favorite toppings. And just like that we have a whole fajita meal in a fraction of the time of traditional methods with all the fresh, vibrant flavors we know and love.
Fun Fact
Chicken fajitas are believed to have originated in Texas, where ranch workers of Mexican descent combined Mexican culinary techniques with ingredients commonly available in the region, such as skirt steak. Chicken was later substituted for beef as an alternative protein option, creating the now-popular dish known as chicken fajitas.
Ingredients
We like to keep things simple and this recipe is no exception. Fajitas seasoning is a mix of simple, pantry-friendly ingredients.
Seasonings include:
- Chili powder
- Cumin
- Smoked paprika
- Garlic powder
- Salt
- a pinch of sugar
Our main ingredients include:
- Chicken breast, thinly sliced
- Red bell pepper
- Green bell pepper
- Onion
It all comes together with some olive oil.
Preparation
We start with 1lb of fresh boneless, skinless chicken breast. Pat the chicken dry and trim off any visible fat. If they are very thick, pound them to an even thickness of about ½″. Alternately, you can place the breast on a cutting board and hold it flat with the palm of your hand, while carefully using a sharp knife to slice horizontally through the middle of the breast, keeping the knife parallel to the cutting board, until you have two even, thinner pieces. Now, cut the chicken against the grain into thin strips, approximately ¼ to ½ inch thick.
Pro Tip: Slice the chicken breast at a 45-degree angle. Cutting at this angle increases the surface area of each piece for better seasoning absorption and even cooking, while also shortening muscle fibers for more tender chicken strips in your fajitas!
Now it’s time to slice the bell peppers into strips, as well as the onion. For the onion, first remove the stem and root ends and peel away the outer skin. Next, place the onion on its side and slice it into even, circular rings. Finally, take each ring and cut it in half to create semi-circular onion slices.
Place the chicken and veggies into a bowl, toss with the vegetable oil and coat everything with the seasoning mix. Make sure to get all the pieces well-coated.
Line a sheet pan with foil or parchment paper and spread out all the seasoned vegetables and chicken into an even, single layer. Separate pieces of chicken that are stuck together as best possible.
Bake at 400°(F) for 18-22 minutes
Place the loaded sheet pan into an oven preheated at 400°(F) for 18-22 minutes. The internal temperature of the chicken should be 165°(F), and the vegetables will become tender.
When done, remove from oven and they’re ready to serve!
How to Serve
One of the things I love about making fresh, homemade fajitas is setting out all the toppings. The fajitas will be served on warm, flour tortillas. You can heat them up on a pan real quick or in the microwave for a few seconds. Then use tongs and load up the tortillas with the mixture.
Favorite toppings for chicken fajitas include:
- Shredded cheese
- Guacamole or avocado slices
- Sour cream
- Pico de gallo
- Salsa
- Jalapeño slices
- Fresh chopped cilantro
- Lime wedges for a squeeze of fresh lime juice

Frequently Asked Questions
Simply store in an air-tight container in the refrigerator for up to 3 days. You can also package for meal prep! Simply place the amount of cooked fajitas you you want in each tortilla in individual zip-top bags or wrap tightly with plastic wrap. Then store in an air-tight container with toppings and tortillas.
Absolutely you can! Cook time will be the same.
Sugar in fajita seasoning adds a touch of sweetness, balancing the spiciness, tanginess, and savoriness of other ingredients. It can aid in caramelization, creating a more appealing appearance and richer flavor when the fajitas are cooked, especially considering we are baking these in the oven and won’t get the caramelization we’d normally get using other, traditional methods.
As written, it is not. The chili powder you use may contain a hint of cayenne that can give the flavor profile a little heat, but otherwise, it is on the mild side. Add cayenne for additional punch!
Yes it can. Simply use thinly sliced flank or skirt steak. The cooking time will be close to the same. Just keep an eye on doneness of the steak strips for desired outcome.

I followed all your instructions except the seasoning. I used a the seasoning from Low Histamine Baby since I couldn’t eat yours due to food intolerance. It was perfect. Fast, easy and delicious! I will definitely be making this often. Thanks.
Fennel says
I’ve been making this since it was introduced; we have it at least once every two weeks, sometimes more. The recipe is perfect as written although I sometimes add some slices of jalapeño and I also squeeze a lime or lemon over it before serving. Yum! In Texas, where I’m from, fajitas are generally served with a side of refried beans which are really good spread over the tortilla. Yum, yum!! Mucho kudos, Jason!
