Yes. Reusing pickled onion [1] brine for 2 to 3 times is generally considered safe, but it is essential to use proper storage and hygiene practices to avoid potential health risks.

To reduce the risk of contamination, transfer the brine to a clean, airtight container and store it in the refrigerator. 

Use the brine within a few weeks and discard any that appears cloudy or has an off smell. Diluting the brine with water is also an option to make it milder and more versatile for cooking.

  1. Salad dressings: Use pickled onion brine as a base for a tangy salad dressing. Mix the brine with olive oil, honey, and Dijon mustard for a simple vinaigrette.
  2. Marinades: Add pickled onion brine to marinades for meats, poultry, or tofu. The acidity of the brine can help tenderize the meat and add flavor.
  3. Pickling other vegetables: Use the pickled onion brine to pickle other vegetables, such as carrots, radishes, or cucumbers. Slice the vegetables thinly and add them to a clean jar with the brine.
  4. Cocktails: Use pickled onion brine to add a tangy twist to your favorite cocktails. Mix the brine with vodka or gin, or add it to a Bloody Mary for extra flavor.
  5. Soups and stews: Add pickled onion brine to soups and stews for a tangy kick. It works particularly well in bean soups and chili.
  6. Deviled eggs: Add a tablespoon or two of pickled onion brine to the filling of deviled eggs for a tangy twist on a classic dish.

How To Store Pickled Onion Brine

  1. Transfer the brine to a clean, airtight container.
  2. Label the container with the date to know how long it has been stored.

  4. Make sure the container is tightly sealed to prevent air from getting in.
  5. Use the brine within a few weeks. While pickled onion brine can last for several months in the refrigerator, it is best to use it within a few weeks to ensure its quality and freshness.
