Step 1: Prepare the Onions

Step 3: Pack the Jars

Sterilize 16-ounce Mason jars by boiling or washing in hot, soapy water and rinsing thoroughly. Pack the sliced onions into the jars, leaving about ½ inch of headspace at the top. Add one garlic clove per jar and any optional herbs or spices for flavor. Ensure the onions are tightly packed but not crushed.

Step 5: Process the Jars for Canning

Place the jars in a boiling water bath, ensuring water covers jars by at least 1 inch. Boil for 15 minutes. Carefully remove jars and place on a kitchen towel to cool. You should hear the lids pop as they seal, indicating a proper vacuum seal. Allow jars to cool completely, about 12 hours. Check seals before storing. Lids should not flex when pressed.

How to Serve

Pickled red onions can be served as a topping for tacos, burgers, or grilled meats. They enhance salads, roasted vegetables, and sandwiches with a bright, tangy crunch.

They also pair beautifully with creamy dips or spreads, offering contrast in both flavor and texture. For platters and charcuterie boards, arrange onions in small bowls or jars to maintain color and freshness.

Additional Tips

  • Use fresh, firm onions to maintain crispness during pickling.

  • Maintain a gentle simmer for the brine; boiling too aggressively can alter the flavor.
  • Leave headspace in jars to allow for expansion during processing.
  • Always use sterilized jars and lids to prevent contamination.
