Healthy and flavorful Chicken, bell peppers, onions, garlic, and fajita seasoning all bake in one sheet pan in under 30 minutes. This quick sheet pan meal makes a delicious weeknight dinner with minimal mess and clean-up! 

For years I’ve been making fajitas at home and every time I’ve always aimed for that smokey grilled flavor that authentic fajitas must-have. I didn’t expect the authentic flavor with the baked version but boy was I surprised. Turns out roasting the chicken and vegetables in the oven gives them that slightly charred edge and smokey authentic fajita favor.


To make these delicious fajitas you will need:

Chicken breasts: Chicken breasts work best because they cook quickly and are healthy too. They can easily be replaced with boneless skinless chicken thighs or sliced steak if desired.

Bell pepper: Bell peppers are an essential part of chicken fajitas and are highly recommend for the full experience. For a colorful dish, we like to use a mixture of red, yellow, and green bell peppers but whatever you have on hand will work!

Onion: Onion will add so much flavor and texture to the dish and is another essential part of chicken fajitas. We highly recommend using it as any type of onion will work well.

Garlic: The garlic is optional because we are already using garlic powder but I LOVE garlic especially in Mexican dishes because it adds so much flavor.

Olive oil: Olive oil is a healthy option but it can also be replaced with any vegetable oil or even avocado oil, as desired.

Fajita seasoning: You can use store-bought fajita seasoning mix if desire but we highly suggest trying our homemade version which is so much healthier, cheaper and tastier than store-bought seasoning!


Making sheet pan chicken fajitas is as easy as combining all the ingredients in a large bowl and baking in a sheet pan for 20 minutes or until the chicken is cooked through and the veggies are charred and tender.


For the spice mix, you can use a store-bought packet or try my homemade version which is so much better!

To make the homemade version you simply combine chili powder, paprika, cumin, ground coriander, garlic powder, salt & pepper.

To make extra simply double or triple the ratios and store in an airtight container for future recipes!

  1. I have not tried this yet but I am putting this as one of the recipes in a meal plan I am creating for someone. This looks delicious and I will definitely try it out myself!

    I have one question though. This recipe feeds 6 people so what would you consider to be equal to 1 serving? I need to know this to track macronutrients in MyFitnessPal.

    I would really appreciate your response to this question and I hope to hear from you soon!

  2. Yum! Made this in a pinch after realizing it was too late to start the slow cooker Mexican shredded chicken I had planned! Oops. I used my premixed taco seasoning as it’s about the same as the spice blend here. Preheated a stoneware sheet pan to 400F convection roast setting, slid the chicken and veggies on (sizzle sizzle!) and they chicken was cooked in 10 minutes! I broiled it for 5, I would have done it a bit longer but realized that my stoneware pan probably isn’t supposed to be under a 500F broiler! (I checked that manufacturer’s website and it is safe to 550- so next time I will broil a bit longer). Served on homemade keto tortillas with avocado, shredded cabbage, cilantro and green onions. I wanted sour cream but I’m out. Sads. Will have to make again. Could make a smaller amount in a preheated cast iron skillet, I bet that would give the chicken a nice dark sear!

  3. is the fajita mix in addition to all the dried seasonings, or are the listed seasonings the fajita mix?

    1. Yes, the spices listed are the spice mix but you can use fajita seasoning INSTEAD if you’d like. Enjoy!

  4. Tried this yesterday and it was soooo good! The chicken was juicy and had great flavor from the seasoning and veggies.

  5. I am going to make this tomorrow. Can’t wait. My question is, why is the Fajta Seasoning Mix different than the Fajita seasoning Mix in the One Pan Chicken Fajitas?

    1. I don’t like to stick to exact recipes every time I cook. I like to switch up the spices but they are both very similar!

  6. Made this tonight and it was easy and very delicious! Didn’t add as much cumin as I’m not very fond of it. Before broiling I put cheese on top. So glad I pinned this 🙂 thank you!

  7. This looks delicious! Do you know the calories for two fajitas?

  8. Do you have a printer friendly version? Want to try this for dinner tonight :). Thanks!

    1. Never mind. . After a lot of scrolling I found it lol.
