Recipe FAQ’s
Can I use brown rice instead of white rice?
Yes! However, brown rice takes longer to cook, so you may need to increase the baking time and add extra broth.
Can I make this dish ahead of time?
Absolutely! Assemble everything in the baking dish, cover, and refrigerate until ready to bake. You may need to add a few extra minutes of cooking time.
What’s the best cheese to use?
A Mexican cheese blend, cheddar, or pepper jack works best for a gooey, melty topping.

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! 🙂
This was delicious but my rice didn’t cook all the way, it was crunchy, which ruined the dish. I used brown rice and cooked it for 40 min covered and about 15 min uncovered (I was trying to get rice to cook more). What could I do differently next time? This is too good not to make again!
