Step-by-Step Preparation
Step 1: Slice the Onions
Peel and thinly slice your red onions. Thinner slices absorb the brine faster, giving you quick pickled onions ready in no time.

In a saucepan, combine the red wine vinegar, water, sugar, and salt. Add optional spices like garlic, peppercorns, or bay leaf for added flavor. Bring the mixture to a light simmer, stirring until the sugar and salt dissolve.
Step 3: Pack the Onions
Place the sliced onions into your clean jar. Don’t pack too tightly—allow room for the brine to circulate.

Carefully pour the hot brine over the onions until they are fully submerged. Use a spoon to press them down if needed.
Step 5: Let It Cool
Let the jar cool to room temperature (about 30–60 minutes). Once cooled, seal the jar and refrigerate.
