Peppers are stars in the summer garden, but quickly fall to autumn’s chilly frost. If you’ve still got peppers coming in from the garden, it’s time to get picking and preserving before the season ends. Here are a few ways to preserve peppers for winter use.
Note: When working with peppers, particularly hotter varieties, it’s a good idea to wear gloves and safety glasses and work in a well-ventilated area. We sometimes even wear masks when working with large quantities of hot peppers. While you wouldn’t normally do this to cook a pepper or two, processing large quantities of peppers can be extremely irritating.
Preserve Peppers with Pickling
If you love pickled banana peppers on sandwiches or pickled jalapeños on your nachos, this one is a great option. Pickled peppers are simple to make and safe for water bath canning, a straightforward process to make them shelf-stable at home.
You can create traditional pickled banana pepper or jalapeño rings or opt for something with a bit more seasoning, like this recipe for marinated peppers, which works well with bell, Hungarian, banana, or jalapeño peppers.
Ferment Your Own Hot Sauce
Hot sauce is a pantry staple, but few people make it at home. While there are hot sauce recipes that are as simple as blending peppers, vinegar, and salt, there’s also some amazing hot sauce recipes that rely on fermentation. The process isn’t as difficult as it sounds and is part of the flavor of some popular commercial brands like Sriracha and Tabasco.
You can use many varieties of peppers to ferment your own hot sauce. Serious Eats has a great deep dive into fermenting hot sauce at home, including how to select a hot sauce style, choosing your peppers, preparation, and even adding some additional flavors.
Preserve Peppers by Pressure Canning
Peppers are a low-acid food, meaning that if you want to water bath can them, you must pickle in vinegar, as mentioned above. If you want plain peppers without vinegar, you’ll need to pressure can them.
Pressure canning is a little intimidating, but it’s easier than you’d think and is a great way to put up many low-acid garden vegetables like green beans, peppers, or sweet corn. Pressure-canned foods are shelf-stable and ready to go when you need them.
The National Center for Home Food Preservation has instructions for pressure canning peppers and some great resourcesfor folks new to pressure canning.
Create Your Pepper Powders or Flakes
Drying or dehydrating your peppers is a great way to make your own spices or seasoning mixes. Drying works especially well if you’ve grown paprika, chili, or spice peppers, which have thinner, more tender skins and plenty of flavor.
If you’ve ever seen strings of chili peppers, you know that they’re an easy vegetable to air dry, as long as you can keep them somewhere warm and dry. To air-dry them, it’s best to string them. Thread a needle and create a loop at the tail end for easy hanging once you’ve threaded the peppers. Then thread the peppers by pressing the needle through the green stem or cap. Some people prefer to dry them indoors, while other people dry them into the open air and sunlight. Air-drying peppers can take 3 to 4 weeks.
For faster results, you can use a dehydrator. Depending on the variety and thickness, a temperature between 125° and 140°F will work well. Lay your peppers on the dehydrator rack in a single layer with air space between them. Large peppers may need to be sliced.
It can be tricky, but you can also dry peppers in your oven; you just don’t want them to get too hot and burn. Lay your peppers in a single layer on a cookie sheet with space between them. Turn your oven to its lowest setting and then place the peppers in with the door propped open with a wooden spoon. You can also turn the oven on for a bit and then turn it off again for a while, alternating until the peppers are dry.
No matter what method you use, you want your peppers to be dry and crisp. Then you can process them into chili flakes, spice blends, or even hot sauce.
Freeze Your Peppers
Unlike many other vegetables, peppers don’t have high levels of enzymes that cause flavor and color loss in the freezer. This means you can skip blanching! Peppers are one of the easiest vegetables to freeze.
Cut your peppers into strips or chunks that you’ll use in recipes, then lay them on a cookie sheet in the freezer. Once completely frozen, you can transfer them to a container or bag, or vacuum seal them, and they won’t stick together.
Preserve Peppers in Salsa
Salsa and chips are a top-tier snack, and a colorful jar of homemade salsa makes it even better! Depending on the recipe, you can incorporate bell peppers, poblanos, jalapeños, and more.
As salsa typically contains plenty of acidic vinegar, it’s safe for water bath canning; just make sure you use a tested recipe. Here’s a great roundup of 60+ tested salsa canning recipes so you can find one that suits your taste.
Peppers are a beautiful and flavorful powerhouse of the summer garden, but a few good pepper plants can result in armloads of peppers that’s tough to use. This fall, as frost approaches, try one of these ways to preserve peppers from your garden.
