How to Make Quick Pickled Red Onions

Step 1: Pack the Jar

Pack the sliced red onion into a pint-sized jar. Ensure it is very tightly packed; this helps create enough brine for proper pickling.

Step 2: Prepare the Brine

  1. In a small saucepan or microwave-safe bowl, combine water, vinegar, sugar, and salt.
  2. Heat the mixture on the stove top or in the microwave until it just starts to boil.
  3. Stir until both the sugar and salt have completely dissolved.

Step 3: Pour Over Onions

Once the brine is ready, pour it over the packed onions in the jar. Make sure all slices are submerged in the liquid.

Step 4: Let it Rest

Let the onions rest at room temperature for at least 30 minutes if they are very thinly sliced. If they are thicker slices, allow more time.

Step 5: Refrigerate

After resting, refrigerate your Quick Pickled Red Onions. They will keep well in the fridge for up to three weeks! Enjoy adding this zesty topping to your favorite dishes!

Common Mistakes to Avoid

When making Quick Pickled Red Onions, a few common mistakes can affect your results. Here are some tips to ensure your pickled onions turn out perfectly.

  • Overpacking the Jar: If the jar is not packed tightly enough, there won’t be enough brine to cover the onions. Make sure to pack them in snugly for optimal flavor absorption.
  • Skipping the Brine Dissolution Step: Mixing water, vinegar, sugar, and salt without heating can leave undissolved sugar or salt. Always heat the mixture until everything is dissolved for a balanced taste.
  • Ignoring Slice Thickness: Thin slices will pickle quickly, while thick slices need more time. Adjust your soaking time based on how you slice your onions to avoid under-pickling.
  • Not Refrigerating Promptly: Leaving your onions at room temperature for too long can lead to spoilage. Refrigerate them after 30 minutes to keep them fresh for longer.
  • Using Non-Acidity Compliant Vinegar: Not all vinegars have the same acidity level. Use vinegar that is at least 5% acidity for effective pickling and safety.

Refrigerator Storage

  • Store Quick Pickled Red Onions in an airtight container to maintain freshness.
  • They can be kept in the refrigerator for up to 3 weeks.
  • Make sure to always use clean utensils when retrieving onions from the jar.

Freezing Quick Pickled Red Onions

  • It’s not recommended to freeze pickled onions as it affects their texture.
  • If needed, store them in the fridge instead of freezing for optimal quality.

Reheating Quick Pickled Red Onions

  • Oven: While not necessary, if you prefer warm pickled onions, place them in a preheated oven at a low temperature until warmed through.
  • Microwave: Place a small amount in a microwave-safe bowl and heat in short intervals until desired warmth is achieved.
  • Stovetop: Gently heat on low in a saucepan with a splash of water until warmed through without cooking them down.
