Can I make this casserole ahead of time?
Yes. Assemble the casserole, cover with foil, and refrigerate up to 24 hours. Add 5–10 minutes to baking time if baking from cold.
What temperature should I bake this at?
Most versions bake at 350°F until the cornbread topping is golden and a toothpick inserted into it comes out clean, typically 25–35 minutes.
Can I use fresh cornbread batter instead of mix?
Yes. Substitute a homemade cornbread batter of similar volume for the boxed mix to maintain consistent baking time and texture.
How do I prevent the cornbread topping from burning?
Cover the casserole loosely with foil for the first 15–20 minutes, then uncover to allow the top to brown in the final 10–15 minutes.
Can I double this recipe?
Yes, but use two 9×13-inch baking dishes. Baking time may increase by 5–10 minutes depending on oven heat distribution.
