Preserving Peppers: A Complete Guide to Saving Your Harvest

Last summer, I overestimated how many pepper plants one person needed. The result? Bowls of shiny bells, piles of jalapeños, and a counter that looked like a farmers’ market. I refused to waste a single one. After a little experimenting, I learned that preserving peppers is simple—and once you start, you’ll never let a harvest go to waste again.

If you’ve grown more peppers than you can eat fresh, here’s how to save that homegrown flavor for months to come. Each method is beginner-friendly, and you don’t need any special canning equipment.

Freeze Peppers for Easy, Quick Storage

Freezing is the easiest way to preserve peppers. It keeps their fresh flavor and color without the need to blanch or cook first.

Best for: Bell peppers, banana peppers, jalapeños

Here’s how:

1. Wash and dry your peppers thoroughly.
2. Slice, chop, or dice them. Remove seeds if desired.
3. Spread the pieces on a baking sheet in a single layer and freeze until solid (about 1–2 hours).
4. Transfer to labeled freezer bags and squeeze out the air before sealing.

Frozen peppers keep for up to 8–10 months. Use them straight from the freezer in stir-fries, soups, or casseroles.

Tip: Roasted peppers also freeze beautifully. Roast first for a smoky flavor (see below).

Pickle Peppers for Tangy Flavor

Pickling adds a bright, zesty kick to sandwiches, tacos, and salads. It’s also a great way to use up smaller peppers.

Best for: Banana peppers, jalapeños, shishitos

Quick refrigerator pickle recipe:

1. Slice peppers into rings and pack them into clean jars.
2. In a saucepan, heat equal parts white vinegar and water.
3. Add 1 teaspoon salt and 1 teaspoon sugar per cup of liquid (optional but balances flavor).
4. Pour the hot brine over the peppers, making sure they’re fully covered.
5. Let cool, seal the jars, and refrigerate.

They’ll be ready in 24 hours and taste even better after a few days.

No need to can. These quick pickles last up to 3 months in the fridge.

Roast Peppers for Rich, Sweet Flavor

Roasting brings out a sweetness and depth that even store-bought peppers can’t match.

Best for: Bell peppers, poblanos, Anaheim

To roast:

1. Place peppers on a baking sheet under a hot broiler or directly on a grill.
2. Turn occasionally until the skins blister and blacken on all sides.
3. Transfer to a bowl and cover for 10 minutes to steam.
4. Peel off the skins, remove seeds, and slice as desired.

Store roasted peppers in olive oil in the refrigerator for up to a week, or freeze for long-term use.

Try this: Layer roasted peppers on sandwiches, toss into pasta, or blend into homemade sauces.

Dry Peppers for Long-Lasting Heat

Drying peppers is the best way to make your own crushed flakes or chili powder.

Best for: Cayenne, Thai, ghost, or any thin-walled hot pepper

How to dry peppers:

• Air drying: Thread peppers on string and hang them in a warm, dry place for 2–3 weeks.
• Dehydrator: Set to 125–135°F and dry for 8–12 hours.
• Oven method: Bake at the lowest setting with the door slightly open until brittle.

Once completely dry, store in airtight jars in a cool, dark place. They’ll keep their heat and flavor for a year or more.

Homemade chili flakes: Crush dried peppers with your hands or pulse in a blender for homemade pepper flakes.

Bonus: Mix and Match Your Methods

You don’t have to choose just one method. Try freezing sliced bell peppers for quick meals, pickling a batch of jalapeños, and drying the hot ones for spice blends. The goal is to stretch your harvest and enjoy your peppers all year long.
