Is Jiffy corn casserole the same as corn pudding?
They are close cousins. Corn pudding usually leans more custardy. Jiffy corn casserole is a little more set and bread-like because of the corn muffin mix, but it still stays moist and spoonable.
Can I make this ahead of time?
Yes, with a small asterisk. Because Jiffy has chemical leaveners, the fluffiest result comes from baking soon after mixing.
Best option: Mix the wet ingredients and corn, then keep it covered in the fridge. Store the Jiffy mix separately. Combine right before baking.
Still works option: You can mix the full batter and refrigerate it for 12 to 24 hours. It may bake up a bit denser. Give it a quick stir before pouring into the dish.
You can also bake it, cool it, and reheat it the next day at 325°F until hot.
Why is my corn casserole dry?
Most often it is overbaked or baked in a pan that is too large for the batter. For this single batch, use an 8x8 or 9x9 so it stays thick and tender. Pull it when the center is just set and still looks moist. Also double-check that you used both creamed corn and sour cream.
Can I double it?
Absolutely. Double the ingredients and bake in a 9x13-inch dish (or a large disposable foil roasting pan). Start checking around the 45 minute mark and bake until the center is set.
Can I make it gluten-free?
You can if you swap in a gluten-free corn muffin mix in place of Jiffy. The texture may be slightly different depending on the brand, but the method stays the same. Also, check your creamed corn label. Some brands may be processed on shared equipment. If you are highly sensitive, labels are your best friend here.
Should I drain the corn?
Drain the whole kernel corn. Do not drain the creamed corn. That liquid is part of what keeps the casserole fluffy and moist.
Does pan material matter?
A little. Glass can bake slightly slower and sometimes browns differently than metal. Use the doneness cues over the clock and start checking around 40 minutes either way.
