How to Freeze Peppers & Onions

Do you still have bell peppers and maybe onions in the garden? If not, if you can find them on sale, grab as many as you can. I was so excited we had a bumper crop of peppers in the garden again this year. We are still picking several each week. I wish I could grow onions as well as the peppers, but they never get over golf ball size, so I buy onions instead of trying to grow them. Maybe next year on fresh onions from the garden.

We probably eat at least six meals a week that have peppers and onions in one form or another. Ours may not be as large as the store bought peppers, but they are still just as tasty! Since those babies are so expensive in the winter time, I like to put as many as I can in the freezer. They are great for adding to recipes that are cooked, but not so much for eating raw.

Peppers are extremely healthy too, having more Vitamin C than oranges.

No Blanching Required

Preparing peppers and onions for the freezer is super easy, because they do NOT need to be blanched before freezing. After rinsing, all you have to do is cut them up the way you intend to use them, then spread them out on a rimmed baking sheet to freeze. I use the plastic snap on lids from large cake pans. Spread the pieces out on trays barely touching and freeze for a couple of hours or overnight. When moving the peppers to freezer bags, remove as much air as possible from the bags. You could go ahead and bag them in recipe size portions before freezing, but they tend to stick together. Peppers and onions will keep for about 8 months in the freezer according  to University of Nebraska.

Freezing Bell Peppers & Onion

Whole Bell Peppers – the largest and nicest looking bell peppers are frozen whole for stuffed peppers. The main criteria is that they will stand on their own, sometimes requiring slicing a sliver off the bottom. I carefully cut the top off and remove the seeds, then use a small metal spoon to scrape the veins out. The peppers are then rinsed and set upside down on a dish towel to dry before freezing. Once frozen, they go in gallon freezer bags.

Unfortunately, we don’t harvest enough whole peppers at one time to stuff before freezing, so this is what I do…when I have enough frozen for 2 meals, I’ll plan on making a big pot of spaghetti, using a package of my spaghetti sauce and I’ll cook up a package of raw hamburger out of the freezer, plus make a big batch of brown rice. We’ll have a spaghetti dinner that night, and once the leftovers are cooled completely, I’ll mix enough meat sauce and rice together to quickly fill the frozen peppers. I set the filled peppers upright in a muffin pan to freeze solid before bagging in meal size portions. I’ll plan on a stirfry the next evening using some of the rice, and then freeze the rest in 2 cup portions.

Bell Pepper & Onion strips – I find it easiest to cut large slabs off of the sides of the peppers, then going back and carefully cutting away the veins with my knife. Cut the larger flat pieces into strips. Peel and cut an onion vertically into 8-10 pieces, then separate into individual strips. I generally keep each separated on trays until I get ready to bag them up. Since we don’t get a lot of red bell peppers, I like to use the red pepper strips to mix with green strips and onions for fajitas, to sauté  to put on hotdogs or smoked sausages on buns, or in a stirfry.

Diced Bell Pepper & Onions – prepare peppers and onions as described above, then hold several strips tightly together and cut in 1/2″ pieces. After freezing, if I have enough diced red peppers, first I will put together a bag with equal portions of diced red peppers, green peppers and onions for omelets, etc, where the red pepper pieces will show up. I put the rest of the cut up peppers in quart freezer bags, so I can take out just what I need.

I apologize for the pictures. I had taken nice step by step pictures, but they were lousy when I uploaded them. So I had to take peppers out of the freezer for these pictures and they are a little frosty.

I’ll be back next week with a few more ideas to use all of those peppers!

  1. Our peppers are still finishing out turning red. Some we picked and made stuffed peppers with the other day. I like your spaghetti meat & sauce leftover idea. We use a meat loaf recipe for ours. I also still have onions in the ground, but they’re not supposed to get big I don’t think. So, not sure what to expect. We seem to eat up our bell peppers faster than we can grow them, since Bob moved in a couple yrs ago. Before that, I used to freeze them chopped up like you show here. Now, they don’t last long before they’re in our bellies.

    1. I’m guessing we’ll still get a bunch more, since it’s still in the 80’s and 90’s. I have to pick ours when they are half red, before the bugs get to them. Sometimes they will finish ripening on the counter though. May be a garden expansion in your future? 🙂


  2. I am lazy. I chop up my sweet peppers and put them directly into a baggie that has a slider top and freeze. When I need some I just take them out of the freezer and bang them on the counter and they break apart. Take what I need and put the rest back into the freezer. I have been doing this for decades. You have to make sure you don’t freeze them in a big ball but nice and flat so the chunks will brake off when you smack them on the counter. I was given red, yellow and orange sweet peppers last week that I froze for the winter. I like to use them in potato salad and other salads for color. I just put the frozen chopped peppers directly in the salads. They taste fine and add a lot to the salad.
