Instant Pot Frozen Corn
I talk all about of how to cook frozen corn on the cob in a machine like this, boiled, in the air fryer or otherwise. I’ll say this maintains the most flavor and nutrition steaming to tender. 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…… The biggest surprise when experimenting with these too is that the timing doesn’t really change!! The same with other foods too, you can use either and get the same results.
Ninja Foodi Option
Directions are the same no matter what brand of pressure cooker you have. BUT with this you could air crisp it as an alternative too which is fabulous. 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.

How long does it take to cook corn on the cob in a pressure cooker?
Fresh corn on the cob – Place in vegetable steamer basket with 1.5 c. water = 2 minutes. But for frozen corn on the cob – Place in vegetable steamer basket with 1.5 c. water = 3 minutes
Cook time for a frozen bag of corn
With fresh kernels cut off of the cob you would use enough water to cover kernels, at least 2 cups = 1 minute on high pressure for tender. If you are adding frozen kernels covered with broth or water to cover it which is typically 2 cups worth and cook on high for 2 minutes with a natural release for both.
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.

Tips
You need some liquid to steam and a way to keep the food out of the water below. Any type of liquid works though for steaming. 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.
Do a natural release for 1 minute for the best tender texture, then a quick release when done and serve immediately. The added time at the end will allow it to continue to steam as it sits in there. I have actually forgotten about them for up to 10 minutes before releasing the rest of the steam and they were just as good. 😉
** Note – Just like with Corn on the Cob in the Oven, cook times may vary very slightly if you are cooking very large cobs that are frozen. Otherwise this should turn out perfect every time using these times. You can also make air fryer corn which is a close second to how well this turns out.
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 when you submerge them into very hot water that sucks them right out.
