Recipe preparation

Essential Ingredients

Here’s what you’ll need to make this delicious dish:

  • Red Onions: Pick firm, fresh bulbs for maximum crunch and flavor—avoid any that feel soft or look sprouted.
  • White Vinegar: This gives the tangy kick essential for the pickle flavor; you can also use apple cider vinegar if preferred.
  • Sugar: A touch of sweetness balances the acidity; adjust it based on your taste preference.
  • Salt: Use kosher or sea salt for best results—avoid table salt as it can dissolve too quickly.
  • Spices (optional): Add peppercorns or mustard seeds for an extra flavor boost; feel free to experiment!

The full ingredients list, including measurements, is provided in the recipe card directly below.

Let’s Make it Together

Prepare Your Ingredients: Start by thinly slicing the red onions; aim for about 1/8-inch thickness for optimal brining. Use a sharp knife or mandoline for even cuts.

Mix the Brine: In a medium pot, combine white vinegar, sugar, salt, and any spices you choose. Heat over medium until sugar dissolves completely—this should take about 1-2 minutes.

Add the Onions: Once the brine is hot (but not boiling), remove it from heat and add in those beautiful onion slices. Stir gently to coat every slice with that delicious brine.

Pack into Jars: Using tongs or a fork, carefully transfer the coated onion slices into clean jars. Pour remaining brine over them until fully submerged—make sure they’re packed tightly but not squished.

Cool & Refrigerate: Allow jars to cool at room temperature before sealing them. Store in the refrigerator for at least one hour before enjoying—though they get even better after 24 hours!

These quick pickled red onions will keep well in the fridge for up to two weeks—if they last that long! Enjoy them on tacos, salads, sandwiches—you name it!

Serving and storing

Add Your Touch

Feel free to experiment with different vinegars, spices, or even adding a dash of sugar for sweetness. You can also toss in herbs like dill or cilantro for extra zest.

Storing & Reheating

Store pickled red onions in a sealed jar in the refrigerator for up to two weeks. No reheating is necessary; just enjoy them cold directly from the jar.

Chef's Helpful Tips

  • Always slice onions as thinly as possible; this helps them absorb the pickling brine faster.
  • If you’re sensitive to onion fumes, chill them before slicing to minimize tears.
  • The longer the onions pickle, the better their flavor becomes!

I remember the first time I made pickled red onions for a family barbecue. My uncle couldn’t stop raving about how they transformed his favorite pulled chicken sandwiches into something extraordinary.
