These Sheet Pan Chicken Fajitas are a favorite Mexican weeknight dinner recipe that’s ready in only 30 minutes. Seasoned chicken breast, bell peppers, and onions are baked on one sheet pan all at the same time!
Say hello to the easiest way to make fajitas ever – on a sheet pan! Whether you make them for taco night or incorporate them into your weekly meal prep routine, these fajitas will not disappoint.
Highly seasoned with my favorite blend of Tex-Mex spices like ground cumin, chili powder, garlic powder, and smoked paprika, this sheet pan dinner is packed with flavor and requires very minimal effort. It’s also low in carbs, high in protein and packed with veggies.
It’s pretty much everything you could ever want in an easy dinner recipe!
How to make Sheet Pan Chicken Fajitas
To make this recipe, all you need is one large mixing bowl and one large baking sheet.
- Add sliced chicken, bell peppers and onions to a mixing bowl.
- Toss together with fajita seasoning, olive oil and a splash of white wine vinegar.
- Transfer to a large baking sheet and bake for 20-25 minutes at 425°F.
That’s it! No need to flip the chicken and veggies halfway through cooking. Leaving them in the oven undisturbed really helps to caramelize the peppers and onions, which adds a beautiful rich and deep flavor.
Once out of the oven, sprinkle some fresh lime juice and cilantro on top for extra flavor. Then eat up!
I love serving these sheet pan fajitas in corn tortillas with a drizzle of Mexican crema and cotija cheese. They make for a super quick and easy taco night during the week that is always welcome in my house.
