Drying, an age-old preservation method, has stood the test of time as a straightforward and effective way to extend the shelf life of chili peppers. Throughout the centuries, people have harnessed the power of air and sunlight to naturally dry these fiery gems. Thanks to technological advancements, such as the dehydrator, preserving chili peppers has never been more convenient, offering consistent results and a taste of history.

Whole peppers

Whole peppers are a versatile preservation option, ready to rehydrate and infuse dishes with vibrant flavors. Whether you reconstitute them for intense heat or grind them into seasoning, these peppers offer adaptability. They can elevate soups, stews, and chilis while serving as a convenient spice source. Remember that drying whole peppers can take significantly longer than sliced ones.

Chili powders

Chili powder, a culinary essential, is a transformative outcome of drying chilis. Regardless of the variety’s heat, the process involves thorough drying followed by grinding into a potent powder. This homemade chili powder elevates dishes with its distinct warmth all year round, offering creative freedom to preserve chili types separately or craft personalized spice blends.

Crushed peppers

Crushed dried pepper is a fiery delight, adaptable to various chili types. Common in pizzerias, this form is easily achieved by drying and grinding chilis coarsely. Its culinary uses are extensive, adding zest to sauces, soups, seasonings, and rubs or enhancing pizzas with an exhilarating kick.


Freezing peppers is a highly effective preservation method, allowing you to enjoy their flavors for 9-10 months, bridging the gap to your next harvest. Its simplicity requires minimal effort yet yields long-lasting freshness—ideal for gradual pepper yields that might not suffice for larger culinary projects. 

You can harvest and freeze peppers whole or slice them into strips for future sautés and sauces. If your peppers are coming in slowly and you don’t quite have enough to make a big batch of hot sauce, you can freeze them as you harvest and save them until you have enough. 

Unlike many veggies, you don’t have to blanch peppers before freezing, making it extremely convenient and easy. 

Freeze drying

Beyond the simplicity of freezing or traditional drying, freeze-drying emerges as a sophisticated method, impressively extending the shelf life of your peppers up to 25 years. This meticulous process impeccably preserves your produce’s nutritional content while maintaining the texture, color, and flavor of fresh peppers, setting it apart from other methods.

However, the benefits of freeze drying come with considerations. This technique requires specialized equipment, freeze dryers, which can be costly and bulky. While a few home freeze dryers are available on platforms like Amazon, many opt for established brands like Harvest Right. The investment may demand thoughtful planning, but the rewards in extended preservation and culinary quality are substantial. I’m hoping to get a Harvest Right freeze dryer within the next few years.


Canning, a centuries-old preservation method, reliably extends the shelf life of your peppers. This technique is easy to do at home with proper tools. There are a few different methods you can try, including water bath canning, pressure canning, and steam canning.

Note that canning unsafely can lead to botulism, a severe foodborne illness. Prioritize trusted recipes from sources like university extensions and reputable brands like Ball, who has a number of canning cookbooks you can buy. Given peppers’ low pH, safety hinges on introducing an acidifier during water bath canning or opting for pressure canning if not using one.

A diverse array of recipes exist for canning peppers to ensure long-term storage:

  • Salsas: Elevate your dishes with the vibrant flavors of salsa, an excellent candidate for canning.
  • Moles and Chili Sauces: Preserve the richness of mole and chili sauces to enhance future culinary creations.
  • Pickled Peppers: Transform peppers into tangy delights by pickling them, ready to add a burst of flavor to your dishes.
  • Pepper Jelly: Craft delectable pepper jellies, a delightful accompaniment for charcuterie boards and sandwiches.
  • Cowboy Candy: Enjoy the satisfying combination of sweetness and heat with cowboy candy.

As you delve into the art of canning, remember to prioritize safety.

Fermentation and salt curing

Among the oldest approaches to food preservation, fermentation and salt curing shine as enduring methods. Fermentation utilizes a saline brine, while salt curing relies solely on salt without water. When properly fermented, chilis can last up to 6 months or more. However, it’s vital to prioritize safety by selecting a proven and tested recipe.

Making hot sauce

Hot sauce, a condiment that ignites taste buds and elevates dishes, often falls into two categories: acidified, typically achieved by incorporating vinegar or fermented. These methods contribute to hot sauce’s remarkable endurance, allowing it to retain quality for as long as six months when stored in a cool, dry environment. Crafting hot sauce preserves your peppers and presents an exciting avenue to explore diverse flavors and techniques, offering an array of possibilities limited only by your imagination.

With many techniques available, preserving peppers has never been more accessible or rewarding. From freezing and canning to fermentation and hot sauce creation, we’ve explored various methods to ensure your pepper bounty transcends the seasons. 

Remember that the art of preservation not only extends the life of your peppers but also invites you to experiment, innovate, and savor their flavors in new and exciting ways.
