Freezing corn on the cob is very easy and does not require much prep work. You can use any of the following three methods to preserve this sweet taste of summer. 


Freezing corn on the cob whole is by far the easiest possible method. You simply need to husk the corn and remove all the silks. Then, place the cobs in a reusable freezer bag, and remove as much air as possible from the bag before closing and sticking in the freezer. Just remember to write the date on the bag, so you know when you put it in. 


Another common method for freezing corn on the cob is to blanch the cobs. To do this, you will need to remove the husk and silk from the cobs before adding them to a boiling pot of water. Cook for 7-10 minutes (depending on the size of your cobs), remove from the water, and plunge into an ice bath. Pat dry and cut the corn off the cobs, place into reusable freezer bags or containers, and place in the freezer. 


You can eat corn on the cob raw, which also means you can freeze raw corn. To use this method, husk your corn and remove the silk. Then, cut the corn off the cob and spread it into a single layer on a baking tray. Flash freeze the corn kernels by placing the baking tray in the freezer for 20-30 minutes or until they feel frozen through. Then add the frozen kernels into a reusable freezer container or bag.
