Freezing Peppers & Onions

Peppers and onions are a great addition to many meals. You can often buy them in bulk or marked down for a great deal. But, as fresh peppers tend to go bad really quickly, this post shares how how to prep and freeze sweet peppers and onions!

Even if you aren’t a big meal prepper, I guarantee that having these ingredients on hand and ready to go will be a big time saver (see all my other meal prep tips for beginners).

Whole onions and bell peppers

How-To Steps

Step One

Slice onions from root to tip, then slice off a bit of the top to get a clean edge. This will let you easily peel off the skin. If freezing in halves, cut off the root end.

Sliced onion on a cutting board

Slice peppers in half, cut off the stem, and remove seeds and ribs. You can use red peppers or green peppers, or any color of sweet bell pepper that you like.

I would skip the hot peppers as they aren’t as versatile as the sweet ones.

Please see the recipe card at the end of this post for the exact ingredients and measurements.

Step Two

Lay out halves on a parchment-lined baking sheet or cookie sheet.

Freeze for 8-12 hours – this ensures they will be individually frozen and not stuck together.

Step Three

Label zip-top freezer bags with item and date, then add fully frozen produce.

Recipe Tips

  • Feel free to slice or dice your onions and peppers into smaller pieces if you like – keeping bags of various sizes means you are ready for any recipe.
  • Have a food processor? You can use the dicing disk to make quick work of this prep work!
  • No matter the shape of your peppers and onions, be sure and freeze them in a single layer first before putting them into a heavy duty freezer bag or any other type of airtight container or vacuum-sealed bag.
  • Looks for fresh bell peppers and onions in the produce section of your local grocery store or at the farmers market.

Recipe FAQs

Can you freeze raw peppers?

Raw peppers are easy to freeze without the work of blanching them. You can likely still eat them raw once thawed without losing too much texture.

How long do frozen peppers and onion last in the freezer?

Both should last nicely for 10-12 months – the key to getting them to last longer is to get as much air out of the bag as possible each time you seal it.

How do you freeze cooked peppers and onions?

Freeze cooked peppers and onions the same way you would do with raw ones. Let them cool down after cooking, lay them in a single layer on a parchment paper-lined baking sheet, and freeze for 8-12 hours before placing them in a zip-top bag for long-term storage. Try them in my recipe for Air Fryer Sausage and Peppers!
