FAQ and tips:

Can I make sheet pan chicken fajitas ahead of time?

Yes! Slice chicken and vegetables a day ahead of time, drizzle with olive oil and seasoning. Toss to coat well and store in the fridge. Bring to room temp on the counter while the oven preheats then bake.

What size sheet pan should I use?

Use a large rimmed sheet pan or baking sheet so everything can spread out in a single layer. If the pan is overcrowded, the vegetables will steam instead of roast.

How do I know when the chicken is done?

Cut chicken into similar size pieces so they cook evenly then cook to an internal temperature of 165 degrees.

Can I double the recipe?

Absolutely. Use two sheet pans so everything roasts evenly.
