I’m a huge fan of cooking corn in the Instant Pot — somehow the high, fast heat makes fresh, in-season corn taste even sweeter. This season I’ve also fallen hard for butter bath corn. Sometimes called “milk boiled corn,” this method involves boiling corn on the cob in a mixture of water, milk, and butter. The technique is revelatory — butter bath corn is perfectly seasoned, buttery, and sweet straight out of the pot.

I bet you know where I’m going with this. Combining the two discoveries — that is, cooking butter bath corn in the Instant Pot — infuses the corn with sweet, buttery flavor, making this the only method you need for cooking corn on the cob this summer.

Instant Pot Butter Bath Corn

Adapting the butter bath technique to the Instant Pot is pretty easy if you keep a few things in mind. You’ll need slightly less water than traditional butter bath corn, and you’ll want to set the Instant Pot to cook for just one minute. To avoid buttery water spurting out of the pressure release valve, you’ll use the pot’s natural release of pressure. That means that this method isn’t necessarily faster than the stovetop method, but it will keep your kitchen cool, and is handy when your stove is otherwise occupied.

Instant Pot Butter Bath Corn

Prep time 15 minutes

Cook time 35 minutes

Serves 6 to 12

Nutritional Info


  • 8 tablespoons

    (1 stick) unsalted butter

  • 6 ears

    fresh corn, husked and broken in half

  • 3 cups


  • 1 cup

    whole milk

  • 1 teaspoon

    kosher salt


  1. Place the butter in an Instant Pot or electric pressure cooker and use the sauté to melt it. Turn off the sauté function. Add the corn, followed by the water, milk, and salt.

  2. Lock the lid on and make sure the valve is set to seal. Use the manual fucntion and set for 1 minute of HIGH pressure. The Instant Pot will take 12 to 15 minutes to come to pressure.

  3. When the cook time is up, naturally release the pressure, which will take 20 to 25 minutes. Carefully open the Instant Pot and serve.
