How to Cook Corn on the Cob for Large Crowds: Cooler Corn
I saw one of the most amazing and baffling cooking tips ever, on Pinterest last Fall. I couldn’t wait until corn season returned, so I could give this idea of “Cooler Corn” a try. If you have ever wondered how to cook corn on the cob for a crowd, this is THE WAY!
Cooking corn on the cob for a big crowd, using a pot and water, can take a long time, or use up a lot of pots. By using a cooler (aka Ice Chest), you can cook a boatload of corn at once. Give your cooler a good wash and scrub, then lay out your corn on the cob. Poor two kettles, or pots, of boiling water over your corn. Close the lid of the cooler and let your corn sit for about 30 minutes. Voila!! We gave it a try over Mother’s Day weekend, and it worked perfectly! The corn should be able to sit and remain a good temperature, for a couple of hours.
Some people worry about the chemicals inside the cooler leaking into the food, but I checked with my manufacturer and my cooler is BPA free. You will want to do a quick search to make sure your cooler is BPA free, but these days brands are doing a much better job of keeping our products safe.
All your corn on the cob problems solved with these easy cooking method!

There’s always next reunion!

I’m curious, do you drain the water after the thirty minutes cook time? Thanks!
Corn on the cob is one of my favorite summer time foods. I organized a BBQ for mother’s day and this would have been perfect to test out. Will have to try for Memorial Day Weekend.
Thanks
Good luck!!
I would drain the water so the corn doesn’t get soggy.
Hey Emily, I was just wondering, does the water in the cooler have to be covering the corn? If Im cooking a lot of ears of corn, it seems I may need a couple more than 2 kettles of water. But just wanted to check…
Thanks for your help 🙂
I don’t believe we had our corn completely covered. We did go out and turn the corn on top, partway through. I don’t know if that is necessary, but it’s what we did to ensure cooking. I think the cooler kind of steams the corn.
Great idea! I’m gonna try it for our annual family beach party. Prepare it at home and add a stick of butter to the water. By the time I drive down to the beach they should be ready to eat. I’ll also take the powered cheese and chili a-la mexican style.
That sounds fabulous!!

Just wondering if this safe. Some plastics release chemicals when heated, which would then leach into the corn. I would be very cautious about using any product in so different a manner than it was intended.
I did some calling around and some research and found that this brand does say this is safe.
I have never tried this, but have been wanting to. I heard you can do the samething with potatoes (baked) and other veggies.
Do I need 2 coolers if I’m doing 6 dozen (72) ears?
It depends on the size of your cooler but I would venture to say yes.
Thank you so much. We are going to us this for my Mom’s 75th birthday bash.
How fun! Enjoy!
Any way you could use frozen corn?
I would imagine you can, but the cooking time might be different.
Have you tested this using frozen corn-on-the-cob?
Hi Ann,
I haven’t tested this with frozen corn, but I imagine it would work. I just wouldn’t leave it in the water for very long.
I was assigned to bring corn to family function of 18 people and I used this technique so I wouldn’t have to cook in batches. I loaded up the cooler, corn, and boiling water before throwing into my trunk. My husband thought I was crazy. I did have in there for about an 1hour before serving and worked like a charm! Plus kept me out of the kitchen!! Thanks for the idea!
Awesome, Tasha! I’m so glad it worked out!
I saw some ask about using frozen corn. Has anyone tried it!
Thanks!
Good question! I haven’t heard if anyone has tried it but I’d be interested to know how it turns out.
