Peppers are a must-have in the summer garden. In fact, you’re most likely going to find a few different pepper varieties in my garden, the classic red bell pepper is one of them!

We eat most of our bell peppers fresh right from the garden as a snack. The peppers that reach the kitchen are usually served as a side to a sandwich or we add them to a salad.

I also love making Mediterranean stuffed peppers, we can eat this dish all day long! And I also make a delicious red pepper paste that you must try, and after all that, if I have any peppers left, I can them as roasted red peppers.

Canning Roasted Red Peppers…

Peppers are a low-acid food and for that reason, we have to use a pressure canner to can them. Canning roasted red peppers requires some work, but it’s not hard or complicated.

Equipment You’ll Need…

Before we start, let’s make sure we have all the needed equipment. First, to prep the peppers you’ll need a cutting board and a knife.

For the roasting part, you’ll need a baking sheet lined with parchment paper. An oil sprayer makes it easy to oil the peppers and a spatula makes it easy to scoop the peppers right into a ziplock bag, you’ll see why in a minute.

To can the peppers, make sure that you have jars with new lids (you can reuse rings). My favorite jar size for canning roasted red peppers is a pint, but you can also use half-pints.

You’ll need all of the canning utensils, a clean paper towel to clean the rim of the jar and your pressure canner. I use the Presto canner but this All American canner is also popular.

Selecting peppers for Canning…

Any pepper that you can use for cooking can be canned in this method it doesn’t have to be red bell peppers. You can choose hot peppers like jalapenos or a mild chili pepper like the poblano pepper.

Since we are going to roast and peel the peppers in this method of canning peppers, it will be easier to use medium or large peppers. The really small ones are just hard to clean and peel.

Also, try to choose meaty peppers. They are also easier to peel, however, you can see in the picture above, that the peppers I canned were rather small and not too meaty. It just means that prep work took me a little longer.

I started with 6.5 lb of peppers here and after cleaning them I was left with just under 5 lb. This 5 lb made three pints of canned roasted red peppers.

Roasting Red Peppers For Canning…

Step 1 – some people like to roast their peppers in the oven whole and clean them after they peel them. I prefer to first clean them and then char them. Start by cutting around the stem and removing it.

Then, halve the pepper and clean it from seeds before you quarter it.

Keep working until all of your peppers are clean.

Step 2 – line a baking sheet with parchment paper and lay the peppers in one layer with their skins up. Spray the peppers with oil (doesn’t matter what kind).

Step 3 – roast the peppers in a 400 degrees F preheated oven for anywhere between 10 to 20 minutes (depending on the size of the peppers).

Step 4 – you’ll notice that at some point the skin starts to separate from the flesh of the peppers. Once the peppers reach this stage, take the baking sheet out of the oven and use a spatula to scoop the hot peppers right into a plastic bag. Let the peppers rest for a few minutes in the plastic bag.

Step 5 – after a few minutes open the bag and let the peppers cool for a minute before peeling them. The skin comes off easily at this point.

Keep working until all of your peppers are peeled. I ended up giving the skins to the chickens, but if you have a dehydrator, you can dehydrate them and make powder with them that you can then use as seasonings for soups or many other dishes.

How to Can Roasted Red Peppers…

Step 6 – while you work on preparing the peppers, add about 2” of water to the pressure canner (or follow manufacture directions), set it on the stovetop, and turn the heat to high. Bring the water to a simmer (180 degrees F). Also, wash your jars, lids, and rings well with warm water and soap and set them aside.

Step 7 – once the peppers are ready and the jars are clean, it’s time to pack the jars. Add 1/2 teaspoon of canning or kosher salt to each pint jar (or 1/4 to each half-pint). If you like the taste of vinegar, you can also add 1 1/2 tablespoons of vinegar to each jar but this is optional.

Add the roasted red peppers to the jars. Make sure to leave 1” of headspace…

Then add a little bit of boiling water to each jar, still making sure that you leave 1” headspace. The peppers pack in there pretty well so usually there is not a lot of room for the liquid but do make sure that you add some.

Use the bubble remover to remove air pockets by inserting it between the peppers and the jar. Press the peppers towards the center of the jar and make sure that the liquid fills the spaces between the peppers.

Use a damp paper towel to clean the rim of the jar before centering the lid and closing the jar with the ring.

Step 8 – set the jars on the rack in the canner. Close the canner and turn your heat to high. The weight should be off of the vent at this point. The water inside the canner will come to a boil and steam will start escaping from the vent.

Let the canner vent steam for 10 minutes before placing the weight on the valve. Now watch the gauge. When it reaches 11 psi, turn the heat down to medium-high to keep the pressure on 11 psi. Process pint and half-pint jars for 35 minutes.

If you are using a weighted canner you need to process your jars under 10 pounds of pressure for the same amount of time. Remember to adjust processing time according to the table below if you live at an altitude higher than 1000 feet in elevation.

Once the 35 minutes are up, turn the heat off and let the canner cool to room temperature undisturbed. This will take a couple of hours.

Once the canner has cooled completely, open it but don’t remove the jars right away. Let the jars hang in the warm water for an additional 10 minutes or so before removing them. Set the jars on a kitchen towel on the kitchen counter and leave them undisturbed for at least 12 hours to cool.

Storing Canned Peppers…

Check to make sure that your jars have sealed by pressing the center of each lid. If there is no movement there it means that the jars have sealed and are ready for storage. Remove the rings (cause they rust and stick), wipe your jars, and store in the pantry for up to 18 months.

Using Canned Peppers…

My favorite way to use my canned roasted red peppers is in pasta sauce. This roasted red peppers pasta sauce from the Pioneer Woman has become one of my favorite pasta sauces!

Roasted red peppers are amazing in a grilled cheese sandwich. They go really well with fish, and also with chicken.

Have you ever made roasted red pepper hummus? It’s delicious and you have to try it. And of course, you also must try roasted red pepper soup! These are just a few ideas for you but there are so many more ways to use these canned roasted red peppers.
