Recipe FAQs
Can I make this casserole ahead of time?
This can be made up to a day ahead. Prepare the casserole, cover it, and set it in the fridge until you are ready to bake it.
Can I use frozen corn directly without thawing it?
I recommend thawing the corn first. Otherwise, the dish may have excess moisture, which can alter its overall texture.
How do I know when the casserole is done?
The casserole is done when the center is set and the crackers are golden brown. This typically takes about 45-55 minutes in the oven.
