FAQs

How do I know when the chicken is fully cooked?

I always use a meat thermometer to check that the internal temperature reaches 165°F (74°C). The juices should also run clear when pierced.

Yes! I can prep everything ahead, store it in the fridge, and bake it when ready. It’s a great make-ahead meal.

What can I serve with Cheesy Baked Fajita Chicken?

I love serving it with rice, cauliflower rice, tortillas, or a side salad for a complete meal.

Can I use store-bought fajita seasoning?

Absolutely! A packet of store-bought seasoning works perfectly, but I can also make a homemade blend with chili powder, cumin, garlic powder, onion powder, and paprika.
