- For reference, this is the pressure cooker I have and use for all recipe creations.
- If fresh corn on the cob isn’t in season I opt for something like this.
- Mini ears of corn in the freezer section are super cheap and are the perfect size for little hands.
I will say I prefer fresh, of course, but we live in an area where it snows so during the Winter time they can be expensive. AND let’s just say I am frugal……
Corn on the cob in the Instant Pot
Is it better to steam or boil corn on the cob??
- Steaming is always best, that’s why this method is perfect.
- Boiling any vegetable means you’re losing nutrients.
We will show you how here. Using a vegetable basket and a cup of water you can make kernels tender in just 2-3 minutes!
1. You will lose the natural sweetness.
2. It will become mushy.
You just want to warm it and soften the kernels. Cooking cobs in their freshest state is ideal, right after picking is best.
You can use the one it comes with which is flat. OR use an “old fashioned” vegetable steamer basket that opens up.
I will explain how to cook all kinds of Instant Pot corn but this is the one I am showing you in the pictures here as an example.
- These are the basic steps to making pressure cooker corn, our favorite Instant Pot side dish:
- If using fresh whole cobs I like to cut the ends off like you see here.
- Then remove husks and silks.
- Pour water into your pot with 1-2 cups of water.
- Place fresh or frozen cobs into a vegetable steamer or on a rack so they don’t touch the water.
- If cooking just kernels you will not sure a rack of any kind.
Then close the lid and steam valve.
- Setting valve to venting will not work.
- When done do a quick release and carefully remove corn as it will be very hot.
- Add your butter and salt and enjoy!
Instant Pot corn on the cob
Timing for all different types:
- Fresh kernels – Use enough water to cover kernels, at least 2 cups = 1 minute
- Frozen kernels – Use enough water to cover frozen corn kernels, at least 2 cups = 2 minutes
- Fresh corn on the cob – Place in vegetable steamer basket with 1.5 c. water = 2 minutes
- remove husks and silks
- Frozen corn on the cob – Place in vegetable steamer basket with 1.5 c. water = 3 minutes
Now keep in mind times depend on how many kernels or cobs you put into your Instant Pot. Also longer times mean softer kernels so it depends on your preference.
This is how to cook fresh corn 4 other ways too.
Time needed: 3 minutes.
Instant Pot Corn on the Cob
- Add water
Put a trivet or vegetable steamer basket in the bottom of your Instant Pot. Pour your water into your pot.
- Remove husks
If not already done, remove corn husks and silks. It is easier if you set each one on it’s side, cut off open end and stalk hard end. Then peel them away over a trash can.
- Add ingredients
Place your frozen or fresh corn in the cobs (ours were cut in half) into your pot and close lid and steam valve.
Close lid and vent to closed. Pressure cook on high for 3 minutes for whole cobs of frozen corn on the cob or 2 minutes for fresh corn on the cob. Do a natural release for 1 minute, then a quick release when done and serve immediately for best results.
