How to Freeze Onions Properly: A Step-by-Step Guide

Freezing onions is quite an easy process and you only need the onions themselves and some freezer bags/containers to get the process started and completed.

Below we take a look at the steps to take to properly freeze onions.

Step1: Prepare Your Onions for Freezing

You are going to peel the onions and then slice or chop them up. If you are doing a lot of onions, consider using the food processor to get the whole batch chopped up.

Step 2: Separate into Portions

It is a good idea to portion out your chopped onions before freezing. It makes life easier, as you will now have access to the exact portion you need for whatever recipe you plan on using them in.

Step 3: Place in a Freezer Bag/Container
