Crockpot Corn on the Cob

Sweet, juicy, delicious corn is not just something you imagine tasting. You can hear it too right? That initial crunch of biting into perfectly cooked corn is something we all look forward to!

The fact that we’re adding melted butter with lemon, herbs, and seasonings on top only adds to its deliciousness.

Once it’s done, you can serve it as a side dish or use it in things like shepherd’s pie, and crockpot chicken tortilla soup.

Making corn on the cob in the crockpot takes away the need to watch over a pot of boiling water, you can make a lot at a time, and because it’s electric you can pretty much plug it in anywhere. It’s a portable and an effortless way to make corn!

Why you’ll love making Corn on the Cob in the Slow Cooker

Convenient – Once you dump in the corn, it’s basically hands-off after that. You can walk away and take care of other things, without the worry about water boiling over.

Taste & texture – Crispy, juicy, and buttery and all kinds of messy when you bite into one. We are here for all of it!

Versatile – We love corn in the summer of course, but this recipe is great year-round. No grill is needed, no turning on the oven or the stovetop, and yet the results are amazing whether it’s for a summer cookout or Thanksgiving dinner!

Equipment you’ll need

  • Slow Cooker – This one is my favorite. It’s large enough to feed a crowd!
  • Tongs – You’ll need a pair of these handy for yourself and any guests serving themselves.
  • Herb Scissors – For easily preparing fresh herbs.

Ingredients

Below is a list of the ingredients you’ll need to gather to make this recipe. Scroll all the way down for the full recipe card.

  • EARS OF CORN – We use 5 for this recipe. Shucked and cleaned and then cut in half so they fit nicely in the pot. You don’t have to cut it in half, I just prefer to do this so it’s already ready to serve that way. You can use more than 5 ears and stack them, you’ll just need to adjust cook time.
  • WATER – Needed for cooking the corn. It’s what helps to create steam which helps to get the corn nice and juicy.
  • MELTED BUTTER – Some of this will be cooked at the same time as the corn and some will be added just before serving. All the buttery goodness you can ask for.
  • LEMON JUICE – A nice acidic component that will brighten up the flavors, and cut through the butter a bit, which gives it a nice balance.
  • SALT & PEPPER – Just a bit of seasoning is all these need! Salt on corn is almost the law.
  • HERBS – I use parsley and chives for an earthy herbaceous layer of flavor. Paired with lemon juice, it is amazing! Stick to fresh parsley if you can, but the chives you can use fresh or freeze-dried.

How to make Slow Cooker Corn on the Cob

  1. STEP ONE: Add 1/2 cup of water to the bottom of the crockpot and add your corn on top. It’s ok if they overlap a bit. Whether you’re keeping them whole or cutting them in half, you just want to make sure that they fit mostly in a single layer.
  2. STEP TWO: Mix half of the melted butter, lemon juice, and salt, and pepper then pour that over the corn.
  3. STEP THREE: Cover and cook on HIGH for 2.5 hours or LOW for 4 hours. Make sure there’s always water in the bottom of the pot, you may need to add more.
  4. STEP FOUR: Once it is finished cooking, mix the remaining melted butter with the herbs. You can either pour it right into the crockpot, transfer the corn to a serving dish and pour it in there, or reserve some on the side for people to decide for themselves if they’d like to add the herbs.

That’s what I call easy entertaining!

What to serve with Slow Cooker Corn on the Cob

Tender crispy corn pairs well with so many things. It’s a traditional side for meatloaf and mashed potatoes or Italian roast beef, but it’s also great for all kinds of dinner ideas such as easy garlic steak bites, slow cooker dill pickle chicken, air fryer Buffalo chicken wings, and garlic parmesan chicken.

It makes a great accompaniment to other sides like crockpot baked potatoes and oven roasted potatoes.

Serve it any day during the busy week, on the weekend, or for the holidays. It’s always the right time for corn!

Tips & Possible Substitutions 🌽

  • Use at least a 6-quart slow cooker. It will fit the amount called for in this recipe. If you have something smaller, or even larger, you can easily halve or double the recipe.
  • Each slow cooker cooks differently, you’re essentially steaming the corn so make sure there is water in the bottom of the crock at all times. If it cooks off, add a bit more to avoid burning.
  • Take a shortcut and buy corn that’s already had its husks removed.

How to reheat and store Crockpot Corn on the Cob

How to store leftovers

Keep it fresh by storing it in an airtight container or a zip-top bag. Make sure to cool them completely, otherwise, the residual heat will add too much moisture making them soggy.

How long will corn on the cob in the slow cooker last in the fridge?

When wrapped tightly, it will last for up to 5 days in the refrigerator.

FAQs

How long can I keep the corn on the warm setting?

Corn is always the best tasting and the freshest tasting when eaten right away. However, when serving a crowd it’s not always the case that everyone eats at the same time.

You can keep it on the warm function of the crockpot, and always make sure there’s water on the bottom. Plan for a maximum of two hours before needing to store it in the fridge.

Should I wrap each ear individually in foil?

It’s not necessary or recommended for this recipe. The purpose of the foil is to trap steam. However, the water does this already! Plus, using the lid traps the steam and allows it to circulate back into the corn.

How long can corn be kept at room temperature?

Again, this should be no more than 2 hours.
