Sheet Pan Chicken Fajitas

If I’m ordering Mexican food at a restaurant, there is about a 90 percent chance I’m getting chicken fajitas. There’s just something about those sizzling pans of chicken and peppers that I can’t resist. And if I have leftovers, I’m already planning lunch for the next day or even turning them into a quick omelette for breakfast.

This sheet pan version gives you all that flavor without standing over the stove. Everything cooks together in the oven, which means less mess and a whole lot less effort.

Sheet pan chicken fajitas are simply sliced chicken, peppers, and onions tossed with seasoning and roasted in the oven until tender and flavorful. It is one of the easiest ways to get that fajita flavor at home.

• Oregano – adds a light earthy note

The Secret to Flavorful Oven-Baked Chicken Fajitas

If you want fajitas that actually taste like fajitas and not just baked chicken and vegetables, here are a few key things to keep in mind.

• Roast at high heat. 425 degrees helps everything caramelize

• Spread everything out in a single layer

• Use smoked paprika for added depth

• Finish with fresh lime juice for brightness

These small details make a big difference.

Why Are My Sheet Pan Fajitas Soggy

This is probably the biggest complaint with sheet pan fajitas, and the good news is it is easy to fix.
