What Are Pickled Onions?
Pickled onions are onions that have been preserved in a solution of vinegar, salt, sugar, and various spices. This pickling process gives them their characteristic zing and a longer shelf life. You can use red, white, or even shallots, but red onions are the most popular choice because of their vibrant color and natural sweetness.
Health Benefits of Pickled Onions

- Probiotic Potential: If naturally fermented, pickled onions may support gut health.
- Low-Calorie Flavor Booster: Add flavor without piling on calories.
- Blood Sugar Regulation: Vinegar in the pickling liquid can help stabilize blood sugar levels.

How to Make Pickled Onions in 5 Simple Steps
If you’re wondering how to make pickled onions at home, this simple method is all you need.
Step 1: Prepare the Onions
Peel and thinly slice the onions into rings or half-moons, depending on your preference.
Step 2: Make the Pickling Liquid
In a bowl or saucepan, mix the vinegar, sugar, salt, and hot water. Stir until the sugar and salt dissolve completely.
Step 3: Add Flavors
Add your choice of spices, garlic, or herbs to the jar or bowl with the onions.
Step 4: Pour and Soak
Pour the warm pickling solution over the onions until fully submerged. Let it cool to room temperature.
Step 5: Refrigerate
Seal the jar and refrigerate. Your quick pickled onions will be ready in as little as 30 minutes, but they’re best after a few hours or overnight.
✅ Here are some tips to keep them fresh:
- Use a clean, airtight glass jar to prevent contamination.
- Always use a clean utensil (not your fingers) to take onions from the jar.
- Keep them fully submerged in the pickling liquid to avoid spoilage.
- Store at a consistent cold temperature, ideally below 40°F (4°C).
🔒 If you follow proper hygiene and storage, they may even stay good for up to a month — but for the best flavor and texture, consume within the first two weeks.
If you want longer storage (months instead of weeks), you’ll need to use a proper canning method with sterilized jars and boiling water bath processing.
Storage Tips: How Long Do Pickled Onions Last?
Pickled onions can last in the fridge for up to 2 to 3 weeks. Use a clean, airtight glass jar for best results. Always use clean utensils to remove onions from the jar to prevent contamination.
