  • Fresh Sweet Corn — You want fresh corn on the cob with the husks and silk removed and the corn cleaned.
  • Water — Just a little water helps steam the corn and prevents it from burning in the bottom of the crockpot.
  • Butter — You can’t have fresh corn without lots of creamy butter! Use salted or unsalted, your preference.
  • Seasonings and Herbs — Add your favorite seasonings to the top of the corn before serving. I like to add some salt to bring out the sweetness of the corn, black pepper, and a bit of fresh parsley. You have loads of possibilities like adding grated Parmesan, Tajin, fresh cilantro, or even a drizzle of honey.

Equipment You’ll Need for Crockpot Corn on the Cob

To make this delicious side dish, you’ll need a slow cooker (4-6 quart size should work) and a set of tongs for handling the hot corn. While optional, corn holders are helpful for serving, too.

Serving Suggestions

Need another tasty side dish? Pair the corn cobs with cowboy crockpot beans, red skinned potato salad, or tri-color pasta salad. They’re all perfect for cookouts and potlucks.

Storage and Freezing

Refrigerator: Slow cooker corn is best eaten fresh out of the crockpot, but you can store leftover corn on the cob in an airtight container in the fridge for up to 3 days.

Freezer: I don’t recommend freezing corn after it’s been slow-cooked.

To reheat: cover with a damp paper towel and microwave for 20 seconds, then rotate the ears of corn and microwave for another 20 seconds. Continue until heated through.

Tips and Tricks for Slow Cooker Corn on the Cob

  • If the corn cobs are too large, cut them or break them in half. This will not affect the cooking time.
  • Don’t overcook the corn. This will make it tough and dry. Test the corn for doneness at the minimum suggested cooking time.
  • Use frozen corn if fresh corn is out of season. It will require a slightly longer cooking time and will be a bit softer, but it’s still delicious.

Additions and Variations

Replace the butter. Trying to cut back on saturated fats? Use olive oil instead of butter. Just brush it over the hot corn before applying your seasonings and herbs.

Try different seasonings. You’re not limited to salt. Chili powder, cayenne pepper, paprika, or Tajin (a mixture of red chili powder, lime zest, and sea salt) are all excellent choices.

Add cheese. Sprinkle some freshly grated parmesan cheese or crumbled cotija cheese.

Better with bacon. Doesn’t bacon make everything better? Sprinkle crunchy bacon bits over your ears of corn to elevate the flavor.

Get saucy. Drizzle some honey or hot sauce over the hot buttery corn to make it even more flavorful.

Easy Crock Pot Corn FAQ

How long does it take to cook corn in the crock pot?

You can cook it on high for 3-4 hours or low for 4-6 hours. Easy peasy!

Do I have to wrap the corn in aluminum foil?

No, you don’t need to use foil for this recipe. The corn, along with the added water, creates enough steam to keep the corn moist.

How do you keep corn on the cob warm?

If you need to keep the corn warm for a while, make sure there’s about a cup of liquid in the crock pot along with the corn. Turn the setting to the warm setting and remove the lid to let the steam escape so the corn doesn’t overcook.

Can I use frozen corn on the cob?

Absolutely, you can make easy slow cooker corn from frozen. However, the frozen corn will have a softer texture than fresh corn after it’s cooked.
