Pickled Red Onions Canning Recipe (1)

I grow mostly storage onions and they are cured and stored in baskets on shelves in the coolest part of our unheated basement. These usually last until springtime. As temperatures warm, the onions start getting soft and are triggered to begin sprouting.

We ended up with a bunch of red onions last year. There was no way we would use them up before they went bad. I decided to can a few batches of pickled onions so they would last longer. Now that the storage onions are gone, I still have a few jars of pickled onions left to tide us over until the new crop is ready.

Tips for Pickling Onions

This is a simple canning recipe that relies on pure vinegar to preserve the onions. Here are some tips to make the best quality pickled red onions:

Start with healthy firm onions

This recipe uses red onions, but you can pickle any type of onion from sweet Spanish to pungent yellow. Choose firm onion bulbs with no mold or spongy spots. If your onions are soft or sprouting, consider freezing them instead. Plan on about 3 pounds of onions to fill 6 half-pint jars.

Use commercial vinegar with 5% acidity

You can safely swap the type of vinegar used to pickle vegetables as long as the acidity is at least 5%. I found the white vinegar made a sharp flavored pickled onion, apple cider works well too. But our favorite is the red wine vinegar. It has a nice, slightly sweet flavor.

  • White vinegar is clear vinegar made by distilling corn and rye. It tastes more sour and acidic, but this may be just what you love about pickled vegetables. Choose an organic brand to avoid genetically modified corn.
  • Apple cider vinegar is made from fermented apples. It has a fruity tart flavor that blends well with vegetables. The color is amber brown and may darken your pickles slightly, but the flavor is worth it.
  • Red wine vinegar is my favorite vinegar for pickled onions. It is made from fermented red wine, and adds a slightly sweet fruity flavor to the onions.

How to cut onions without crying

Slicing into an onion releases an enzyme that turns into a vapor that irritates the eyes. In response, your eyes tear up to flush the irritant out of your eyes. Here are tips for cutting onions without crying:

  • Chill the onions: Chilling the onions before cutting to decrease the amount of gas released into the air. Pop the onions in the refrigerator for a couple of hours, or freeze for 30 minutes before slicing.
  • Cut the root last: The root end of the onion has a higher concentration of enzymes.
  • Protect your eyes: Wear kitchen goggles to shield your eyes from the gas.
  • Use a sharp knife: Cutting onions with a sharp knife will release fewer enzymes into the air.
  • Use a fan: Cut the onions in a well-ventilated area and run a fan towards your work area to move the air away from your face.

If your eyes are irritated after slicing onions, flush them with cool water and use eye drops. Wash your hands well and avoid touching your eyes.

How to Can Pickled Onions

Preserving pickled red onions is pretty straightforward. You simply slice the onions, heat a simple vinegar brine, fill the jars, and process in a water bath canner for shelf stable jars. This canning recipe is based on the “Vinegared Red Onions” from the Ball Blue Book Guide to Preserving. It has been adapted slightly to add more flavors to the brine with pickling spices.

If this is your first time canning, or if you haven’t canned in a while, it may be helpful to review theses article on Principles of Home Canning and Using Boiling Water Canners at the National Center for Home Food Preservation website. A more detailed and printable recipe can be found at the bottom, but these are the general steps for making and canning pickled red onions:

Step 1: Prepare the Canning Equipment

You’ll need:

  • Water bath canner and canning rack
  • 6 half-pint canning jars
  • Canning lids and bands (new lids for each jar, bands can be reused)
  • Canning tools: jar lifter, canning ladle, funnel, and bubble popper
  • Plus basic kitchen supplies such as a large saucepan, large prep bowl, liquid measuring cup, kitchen towels, tongs, mandoline, or knife and a cutting board.

Wash your jars, lids, bands, and canning tools in warm, soapy water. Rinse well, and set the lids, bands, and tools aside to air dry until you are ready to use them.

Setup your water bath canner with the canning rack on a large burner of your stove. Place the jars upright in the canner, and add water to cover. Bring the canner to a simmer (180˚F) for 10 minutes, and keep the jars hot until you are ready to fill them.

Step 2: Prepare the onions

Cut off the stem end of the onions and peel off the paper skins. Using a mandolne, or sharp knife, cut the onions into 1/4-inch slices. Freeze the root end and trimmings to use for making homemade stock.

Step 3: Heat the pickling vinegar

Bundle the pickling spices in a spice bag or coffee filter and tie with kitchen string. If you don’t have pre-mixed pickling spice, you can mix up a batch with this homemade pickling spice recipe, or simply combine 1 teaspoon mustard seeds, 1 teaspoon coriander seeds, 1 teaspoon dill seeds, 1 teaspoon black peppercorns, 2 allspice berries, 1 bay leaf, and a pinch of red pepper flakes.

Since this is an all vinegar pickle recipe, you can safely alter the herbs, spices, and even add a little sugar to adjust the flavor to your liking. Feel free to include any dried or fresh herbs and spices, such as oregano, rosemary, fresh ginger, cumin seeds, crushed cinnamon, or star anise. Your spice mixture doesn’t have to be perfect. You just want to infuse the vinegar with extra flavor.

Add the vinegar, crushed garlic cloves, and spice bag to a medium sauce pan. Bring to a boil over medium-high heat, reduce the heat, and simmer (180˚F) for 5 minutes. Add the prepared onions, cover, and simmer for 5 minutes. Remove the garlic and spice bag and fill your jars.

Step 4: Can the onions

Lay a kitchen towel on the counter. Use the jar lifter to remove a jar from the canner, drain, and place on the towel. Keep the remaining jars in the canner, so they stay warm.

Use tongs to pack the sliced onions into the warm jar. Add two sprigs of thyme on top, and pour hot pickling liquid over the onions leaving 1/2 inch headspace. Run the bubble popper through the jar to remove trapped air and compress the onions so they are submerged in the liquid. Remove any that stick out, and adjust the headspace again if needed.

Wipe the rim with a damp towel to remove residue. Center a lid on the jar, place the band over the lid, and screw it on until fingertip tight. Place the jar back into the canner, and repeat with the rest of the jars. Adjust the water level so it is covering the jars by two inches, bring the canner to a boil, and process the jars for the times indicated in the recipe below.

Once processing time is complete, remove the jars, and let them cool undisturbed for 12 to 24 hours. After cooling for at least 12 hours, test the seals. Refrigerate any that did not seal, and use up within a week.

Wash the jars with warm soapy water, dry, label and date the jars, and store in a cool, dark location for 12 to 18 months. Wait several weeks for the onions to develop its flavor before opening a jar.

Ways to Use Pickled Onions

Pickled red onions can be enjoyed in so many ways. The sharp flavor of onion mellows when it is pickled, making it a tasty pairing to most savory recipes. The onions add a nice pop of color, and bite of acidity balances out the flavors of a rich, heavy meal.

  • Sandwich Topping: Try layering your favorite sandwich with a fork of pickled onions. Add them to burgers, wraps, roast beef, and barbecue pulled pork sandwiches.
  • Mexican Dishes: Pickled onions add acidity and texture to your favorite Mexican and Tex-mex style dishes, such as tacos, quesadillas, enchiladas, tostadas, nachos, burritos, and fajitas.
  • Fresh Salads and Salsas: Garnish a leafy green salad with bright pink pickled onions for a pop of color and mild onion flavor. Pickled onions also combine well with mayonnaise-based foods, adding zing to your summer potato salad, macaroni salad, coleslaw, and pasta salads. Chop and add to fresh salsas such as this Italian salsa cruda, grilled salsa, or corn salsa.
  • Meat and Seafood: Add a spoonful of pickled onions over roasted and barbecued meats and seafood, such as chicken, pork, steak, fish, or shellfish.
  • Save the Pickling Liquid: You can use the mild onion-flavored vinegar in any recipe that calls for vinegar. Try drizzling a spoonful of the vinegar on roasted vegetables and oven-baked fries. You can also turn the pickling liquid into tasty vinaigrette that can be used to marinade meat or as a salad dressing.

Ingredients

  • 3 pounds red onions
  • 3 tablespoons pickling spices
  • 4 cups vinegar at least 5% acidity
  • 1 clove garlic crushed
  • 12 sprigs of fresh thyme optional

Instructions

Prepare the canning equipment:

  • Wash your jars, lids, screw bands, and canning tools in hot soapy water. Rinse thoroughly to remove all suds. Set aside to air dry on a clean kitchen towel.

  • Place the jar rack into water bath canner, place jars in the canner, and add water to cover. Bring the canner to a simmer (180˚F) for 10 minutes, and keep the jars hot until you are ready to fill them.

Prepare the onions:

  • Peel the onions and remove the root and stem ends. Cut the onions into 1/4-inch slices. Break apart to separate the segments. Set aside.

Heat the pickling brine:

  • Add the 3 tablespoons of pickling spice to a spice bag or coffee filter and tie with kitchen string.

  • Add the vinegar, crushed garlic cloves, and spice bag to a medium sauce pan. Bring to a boil over medium-high heat, reduce the heat, and simmer (180˚F) for 5 minutes.

  • Add the prepared onions, cover, and simmer for 5 minutes. Remove the garlic and spice bag and fill your jars.

Can the onions:

  • Lay a dry kitchen towel on the counter. Use the jar lifter to remove a jar from the canner. Drain the water back into the canner, and place on the towel. Keep the remaining jars in the canner so they stay hot.

  • Using tongs, fill the jar with the onions, add two sprigs of thyme, then ladle hot pickling liquid over the onions leaving a 1/4-inch headspace.

  • Run the bubble popper through the jars to release air bubbles. Wipe the rim to remove any residue, center a lid on the jar, and screw on a band until it is fingertip tight. Use the jar lifter to place the jar back into the canner, and repeat with the remaining jars.

  • Once all the jars are in canner, adjust the water level so it is two inches above the jar tops.

  • Cover the canner and bring to boil over high heat. Once water boils vigorously, continue boiling for 10 minutes at altitudes of less than 1,000 feet. Adjust processing time for your altitude if necessary (See Notes).

  • When processing time is complete, turn off the heat, and let the canner cool down and settle for about 5 minutes.

  • Spread a dry kitchen towel on the counter. Remove the cover by tilting lid away from you so that steam does not burn your face.

  • Use the jar lifter to remove the jars from canner and place on the towel. Keep the jars upright, and don't tighten bands or check the seals yet. Let sit undisturbed for 12 to 24-hours to cool.

  • After 12 to 24-hours, check to be sure jar lids have sealed by pushing on the center of the lid. The lid should not pop up. If the lid flexes up and down, it did not seal. Refrigerate jar and use up within a week.

  • Remove the screw on bands and wash the jars. Label, date, and store in a cool, dark place for 12 to 18 months. Let the pickled onions stand for about a week before opening for the flavors to develop.

  • Use home canned jars within 12-18 months. Makes about 6 half-pint jars of picked red onions. Refrigerate the jar after opening.

Notes

This is a tested safe canning recipe from the Ball Blue Book Guide to Preserving. Altering the recipe may make it unsafe for canning.

All times are at altitudes of less than 1,000 ft. Adjustments must be made for altitudes greater than 1,000 ft. For altitudes of 1,001–6,000 feet = 15 minutes, above 6,001 feet = 20 minutes.

I am happy to answer any questions, but if you need immediate canning help or answers, please contact your local extension office.
