Freezing Green Peppers & Onions

Green peppers and onions, the veggies of champions. A joyous occasion when I am making meals like meatloaf, and a compliment to mushrooms and spinach when you add a kiss of garlic powder. 

In our house, it is a staple, at least to me. And since I had so many, I didn’t want them to waste. Now, there are many ways to preserve this dynamic duo, such as dehydrating and pickling, but today, we will focus on freezing. Why? Because this is the simplest way to preserve your veggies for future use. Any who, let’s start with the materials.

  • Cutting Board
  • Bowls

  • Ziploc Bags
  • Permanent Marker

Cleaning Your Peppers and Onions

Take time to clean your veggies by running them under some warm water and rubbing off any dirt. After washing all the veggies, make sure that you allow them to dry for a few minutes before you cut them. 

The first veggie we’re going to start with is peppers. I made sure that I cut off all tops and pulled all the seeds and white flesh out of the core. Now, you can cut off as much of the pepper around the stem as you want and throw it in your compost bin. I did a little bit of both. 

As for the seeds, you could preserve those for your garden next year.

Cut up the Peppers

After I removed the top and the seeds, I started to cut the pepper into slices. Now, there is a variety of ways you can cut your peppers. They can be sliced, diced, or kept whole for stuffed peppers. 

In this case, I’m just going to slice and dice mine because it worked well with the recipes I use them for. What type of peppers do we use, Mea? Just feel free to use a variety of sweet bell peppers. Just keep in mind that when it’s green, it has more of a mild, bitter flavor, but as it ripens to yellow or red, it becomes sweeter. Now, another thing about freezing peppers and onions is that you don’t need to blanch them. In other words, dip them in hot water. They will do fine by being put in a Ziploc bag.

Cut the Onions

Next, let’s go ahead and move on to the onions. To remove the brown skin, I cut off the top and bottom of the onion and made a minor cut on the side to go through the first layer. After that, I cut the onion in half and broke them apart. Quick tip about onions. If you are very sensitive to the smell, try putting it in the refrigerator for a few hours before cutting. This can help reduce the impact that it can have on your eyes. As always, do not touch your face when cutting an onion. You can make you cry.

Its Time for Storage

Now, it is time for storage. Make sure that when you are preparing your Ziploc bag, you write the name of the veggies, the date, and a description (i.e., sliced, diced) back. Since I used both green peppers and onions simultaneously, I decided to mix them before freezing. 

After you bag them, make sure that you squeeze all the air out as much as possible, close them up, and lay them flat. This will help with storage in your freezer, preventing the food from becoming one big brick. After getting everything in the bag, you get the air squeezed out, and everything’s labeled; the project is complete. Lay those bad boys flat and stick them in the freezer.

Well there you have it! A simple method to preserving your green peppers and onion. I hope this helps!
