Asparagus is a short-season veggie, but with this simple canning technique, you can enjoy it year-round. This recipe, based on guidance from the National Center for Home Food Preservation, pickles asparagus into a salty, spicy treat your whole family will love.
Pick asparagus that is firm, fresh, and crisp—avoid any wilting or soft stalks. The best asparagus for canning should snap easily when bent. If your store sells asparagus in bundles with a rubber band, ask to remove it to prevent any uneven pressure on the stalks.
Clean and Cut Your Asparagus
Rinse each stalk under cool water. To ensure no dirt is left behind, I prefer to wash each stalk individually. Using a sharp knife, cut the tough bottom end of each stalk. Make sure each piece fits neatly into the jars, leaving about ½ inch of headspace.
Cut one stalk to test the size and use it as a guide to cut the rest of your asparagus.
Clean Your Peppers
While not required, hot peppers add a nice spicy kick to the pickled asparagus. I used serrano peppers, but you can try habanero or Anaheim peppers as well. Cut off the stems and shake out the seeds.
Prepare Your Jars and Lids
You’ll need 6 wide-mouth pint jars for a full batch. Wash the jars thoroughly with hot, soapy water, and inspect them for cracks. Place the clean jars in your canner, cover them with water, and bring the water to a boil. This will sterilize the jars while you work. In a separate saucepan, heat the lids to soften the adhesive.
Create Your Brine
In a saucepan, combine the following ingredients:
4 ½ cups water
4 ½ cups white vinegar
6 prepared hot peppers (optional)
½ cup canning salt
3 teaspoons dill seed
Bring the brine to a boil while stirring occasionally. Be cautious, as hot vinegar fumes can irritate your lungs—turn on your kitchen vent for better air circulation.
Add Garlic to Jars
Peel 6 garlic cloves using the flat edge of a knife to crush them, which makes the skins come off easily. Place one garlic clove in the bottom of each jar.
Pack Asparagus in Jars
Using the jar lifter, remove the hot jars from the canner and place them on a cutting board. Pack the prepared asparagus tightly in each jar, with the blunt ends at the bottom. Leave ½ inch of headspace at the top of the jar to allow for expansion during the canning process.
Pro Tip: To check for proper packing, flip the jar upside down. If the asparagus falls out, it’s not packed tightly enough.
Add Peppers to Jars
If you're using hot peppers, place one pepper on top of each jar. Don’t worry if the peppers float to the top—they’ll still add flavor.
Top Vegetables with Brine
Place your canning funnel over each jar and fill it with the hot brine, covering the asparagus completely. Be sure not to overfill—leave ½ inch of headspace. Run a knife along the sides of the jar to remove any air bubbles.
Apply Lids and Rings
Use a damp paper towel to wipe the rims of the jars to remove any syrup or brine that could interfere with the seal. Using the lid lifter, place a lid on each jar and screw down the ring until it’s finger-tight.
Process the Jars
Carefully place the filled jars into the water canner, making sure the lids are covered by at least 1 inch of water. Bring the water to a rolling boil, cover the canner, and process the jars for 10 minutes. If you're at a higher elevation, adjust the processing time accordingly.
Rest the Jars
After 10 minutes, turn off the heat and remove the canner lid. Let the jars rest in the water for 5 minutes to stabilize. Then, using the jar lifter, remove the jars from the canner and place them on a towel or cutting board to cool.
Test the Lids
After 24 hours, check the seals by pressing down in the center of each lid. If it doesn't pop, the jar is sealed properly. If any jars didn’t seal, place them in the refrigerator and consume them within a few days.
Label and Store
Once the jars are sealed, remove the rings and label each jar with the date. Store them in a cool, dark place. The asparagus will remain good for about a year.
Notes
If you prefer less heat, omit the hot peppers and simply use the brine to preserve the asparagus.
Always make sure there is ½ inch of headspace in the jar to allow for expansion during the canning process.
If you have leftover asparagus bits after cutting to fit in the jars, try roasting them for a tasty snack!
