FAQ – Crockpot Corn Casserole

Can I make this ahead of time?
Yes! Mix everything and refrigerate up to 24 hours before slow cooking.

Can I use homemade cornbread mix instead of Jiffy?

Is it supposed to be jiggly in the middle?
Yes — it firms up as it cools. The texture should be soft and moist, not dry.
