Frequently Asked Questions
Can I prepare Sheet Pan Chicken Fajitas ahead of time?
Yes. Slice the chicken and vegetables ahead of time and store them separately in the refrigerator. Mix the seasoning in advance so everything is ready to cook.
Can I freeze leftovers?
Absolutely. Let the cooked chicken and vegetables cool completely before storing them in a freezer-safe container for up to three months.
Which vegetables work best for fajitas?
Bell peppers and onions are classic choices, but mushrooms, zucchini, and poblano peppers also roast beautifully.
How do I keep the chicken juicy?
Cook only until the chicken reaches 165°F (74°C). Overcooking can make the meat dry.
Are corn tortillas a good substitute?
Yes. Corn tortillas make a delicious gluten-free alternative to flour tortillas.
Storage
Store leftover chicken and vegetables in an airtight container in the refrigerator for up to 4 days.
For longer storage, freeze the cooked fajita mixture for up to 3 months. Thaw overnight in the refrigerator before reheating.
Reheat gently in a skillet over medium heat or in the microwave until warmed through. Add a squeeze of fresh lime juice before serving to brighten the flavors.
