Do the bite sized chicken pieces need to be fully cooked before putting in oven?
Nope, you don’t have to fully cook the chicken first! Just brown it a bit and it’ll finish in the oven.
Can I use instant rice?
Yes, you can use instant rice, but reduce the baking time and check for doneness earlier!
Could you use bone in chicken thighs or drumsticks with skin on? If yes, what would be the steps? Thank you.
Yes, you can! Sear the chicken pieces first until the skin is golden, then place them on top of the rice and veggies in the casserole dish. Bake covered for about 40–45 minutes, then continue with the rest of the steps as usual. Hope this helps! 🙂
