This recipe will make one large and one smaller casserole, so freeze one for later, or serve both to a crowd! I have made this casserole without using the cooked chicken and it is still very good, you can also add in cooked chopped bacon in place of the chicken if desired, then use the drippings for the cornbread! You can bake and then freeze the cornbread up to 1 month ahead if desired, then defrost to use in this recipe. If you don't have a 10-inch cast-iron skillet use a 9-inch round cake pan. Since my family likes spicy, I add in 1-2 jalapeno peppers, seeded and finely chopped into the cornbread mixture, if you like extra heat then add them in! This is a very good casserole! Servings is for both casseroles and is only estimated.
