Cooler Corn:
How to Cook Corn in a Beer Cooler ♥

Cooler Corn - How to Cook Corn in a Beer Cooler
How to cook fresh summer sweet corn in a cooler – and more importantly, why you want to cook those gorgeous ears of corn in one, whether you're camping or not.

Now let me confess right off, I got some grief for cooking corn in a beer cooler. "You might as well cook that corn in the dishwasher," was the less-than-excited response. But a real veggie evangelist will press on even under pressure, ever on the hunt for new and interesting – and always, useful – ways to cook vegetables.

Besides, I was pretty sure my dear Auntie Karen was onto something when she sent me the "recipe" awhile back. (Ha! Is something this easy a recipe? Yes, if it's life-changing, you bet.)

It felt like a good idea for cooking corn outside, camping, say, or for a shore lunch when fishing.
It felt like a good way to cook a whole mess of corn for a crowd with practically zero fuss and muss.

But here's the thing, why this is my new way to cook corn:

I don't have to deal with a huge pot of boiling water, especially emptying said huge pot of boiling water, with hungry corn eaters hanging around.
After just 30 minutes, the corn is perfectly cooked. That's a longer time than usual to cook corn, I understand, but the whole 30 minutes is without attention, letting the corn just cook merrily away, doing its own thing, in a corner of the kitchen or out on the patio or wherever while I pour myself Beer & Ginger Ale.
But more than that, after the cooking time of 30 minutes, the corn holds beautifully without getting soggy or overcooked. Two days in a row we made Cooler Corn, both times serving it more than 2 hours after the 30 minutes of cooking. It was as good as fresh-cooked, no questions asked, maybe even better.

In fact, three generations gobbled up two coolersful of corn this last weekend. The second day, the kids had been romping in the pool for a couple of hours and emerged, hungry, before dinner (this great Carne Asada published in the Sunday NYTimes Magazine, for the curious) was ready. Fending off hunger pangs, I quickly melted some butter on a plate in the microwave and then delivered it, a platter of sweet corn and a roll of paper towels to the patio. Whoosh, a Giant Corn Crunching Sound ensued. Even the six-year old who's more keen on hot dogs and candy than anything resembling a vegetable ate five ears!

So I'm not getting grief anymore, I'm getting, "When can we make some more Cooler Corn, Alanna?"


Hands-on time: 15 minutes
Time to table: 45 minutes
Serves as many as needed

Ears of corn
Boiling water

Wash the cooler inside and out. Depending on how the cooler's been treated, you might want to sterilize it with boiling water!

Shuck the corn, removing the husks and the silks. Rinse the ears under running water, rinsing off any grime that's gotten inside, any-anything that's transferred from the husks to your hands to the ears. If you like, snap the ears in half, drop into the cooler. This can be done in advance, as early as the morning of an evening dinner, I'd think.

Thirty minutes before serving, pour boiling water over the corn, enough to cover and then some. Close the cooler and leave it alone for 30 minutes.

After 30 minutes, check the corn for doneness and eat up!

Otherwise, if you want to serve the corn later, leave the corn in the still very-hot water with the cooler cover closed. Serve up to 2 hours later. (Two hours worked for us twice, any longer I haven't done.)

I've taken to breaking ears of corn in half, more people will take a half ear of corn than a whole ear. Maybe it's just more manageable? Also - a half ear is great for kids.
I was kind of surprised how little butter was used, just rolling the hot ears of corn in a plate of melted butter. For 8 ears, I melted 4 tablespoons of butter, at least one and maybe two were left over.
Word to the Wise: Don't forget to wash the cooler afterward, it gets mighty stinky mighty fast.

That is just plain cool for the summertime! Thanks for sharing!

question: I am no scientist but I wonder about putting boiling water in the plastic... do you know anything about what this might release from the plastic? This sounds like a super technique and I just want to be sure it is not doing funky things to the food.

Thanks for all your work gathering recipes for our tables!

We're talking SWEET corn, aren't we? To keep the most possible sugar in the kernels (including the yellow ones, not just the white ones), husk and parboil as soon as possible after it was picked. Ideally, pick your own, bring it home, then husk and immerse in boiling water one minute. At the very least, keep it COLD, as in ice, in the husk, until just before cooking. This halts the action of the turn-sugar-to-starch enzymes.

Did the boiling water do anything to the plastic interior of the cooler?

Michelle ~ Isn't it just plain summer? I wish I could show you the pictures of three kids gobbling up corn, that was pure victory for me!

TobyBo ~ Uh .... um ... I must admit, I didn't consider this and have no idea.

Anonymous ~ For most of us, the corn's been picked one or more or even more days ahead of time. You're right about the timing but for most of us, it just isn't practical.

Kathy ~ Not that I noticed, it's hard plastic.

If you don't eat the corn after 30 minutes, but let it sit, do you leave it sitting in the water?

Susan ~ Yes, leave the corn in the water. It stays nice and warm, frankly easier to eat than piping hot corn.

BTW I asked the same question. The first time we made this, our swimmer/supper people ran late and so I had the chance to experiment a little. After 30 minutes, I pulled out half the corn and put it on a platter, expecting that after awhile I'd warm it up again in the microwave or maybe in a skillet. Two hours later, the corn that had been left in the cooler was still so good, I put the corn that had been out on the counter back into the warm water and let the ears warm up for a few minutes before serving!

a little confused, after the corn sits for 30 min or more, do you drain the water or let it sit in the water/cooler? thx

This is way cool. Kinda down home sous-vide. ;-) Really, really clever. Thanks for a terrific idea.

I would not think that it is healthy to pour boiling water into a plastic cooler that is not meant to withstand such high temperatures. My concern is what kinds of chemicals leach into the water which your food is now sitting in. An interesting idea in concept, but you won't find me trying this recipe!

As the cooler didn't deform when the hot water was put in it, I imagine it's polypropylene (PP), which is thermostable and used to make microwaveable containers. I would have very little concern over any leaching of chemicals into the water.

I'm also concerned about the boiling water in plastic. If you boiled the water already, why can't you just throw in the corn into the pot and let it sit for half an hour away from additional heat?

Anonymous #1, Please see Anonymous #3's comment.

Anonymous #2, Thanks for that input.

Anonymous #3, I thought of that the other day but haven't tried it yet, but great idea. If the pot holds the heat, it'll work great. You'd have to have a big pot to match the size of even a small cooler but it would alleviate the plastic concern.
