Chicken fajitas just got even easier with this one pan, sheet-pan recipe! Chicken is roasted in the oven with peppers and onions until tender, juicy and caramelized.

Sheet pan chicken dinner recipes are always a lifesaver when it comes to fast and healthy cooking. Whether it’s my Sheet Pan Lebanese Shish Tawook Chicken, Sheet Pan Sausage, Eggplant and Peppers, or Chicken and Acorn Squash Sheet Pan Dinner, I am a huge fan of sheet pan chicken dinners!

What’s great about roasting anything in the oven is that the meat and vegetables caramelize as they cook.

Since my family loves chicken fajitas (including my husband who isn’t a huge fan of traditional Mexican food), we make this sheet pan fajita recipe frequently.


When the sheet pan chicken fajitas come out of the oven you’ll be rewarded with tender, caramelized peppers and onions that have become sweet and delicious.

To serve, scatter the pan with chopped cilantro, jalapeno sliced or lime wedges if you wish. You can serve in a flour tortilla or keep low carb by eating over a bed of Mexican Cabbage Slaw.

Frequently asked questions:
Essentially any recipe that is roasted or baked in the oven on a single pan. I love using a traditional nonstick baking sheet and suggest using the largest size you can find.
Caramelization is essentially the oxidation of sugar which results in the delicious, nutty flavor and brown color you find in roasted garlic, roasted chicken or caramelized onions. Caramelization is a type of non-enzymatic browning reaction.
Any type of bell pepper works. I like to do a variety of red, orange, yellow or green. You can also add in jalapeno or poblano peppers.
We always have boneless skinless chicken breasts on hand but any type of chicken will work. Note: you’ll want a longer cook time for bone-in, dark meat or any other variety. You’ll know the chicken is done when it reaches an internal cooking temperature of 165 degrees or higher.
To season the chicken, I sprinkle it with cumin, fresh garlic, smoked paprika, salt, and pepper. Since these are boneless, skinless chicken breasts you’ll want to drizzle with olive oil as well to keep tender.
Absolutely – shrimp or skirt steak would both work well.
