Ingredients You Need

• Red onion – Buy the thinnest small onion you can find. I have trouble finding small one so I’ll use half a large one, but small are better.
• Apple cider vinegar – Strain it if your apple cider vinegar has the mother in it.
• Water – Warm water, but not boiling.
• Sugar – I use granulated sugar.
• Salt – Sea salt is what I use, small flakes so they dissolve easily.
• Optional: red pepper flakes for some heat

Equipment Needed

• 2x 10-ounce jars with lids – I use these plastic storage jars with hinge lids. You can also use one 20-ounce jar.
• Large bowl or measuring cup – The measuring cup makes it easier to pour the marinating liquid into the jars.

Best Tips for Making Quick Pickled Red Onions

• Slice Evenly: Make sure your onions are evenly sliced to ensure uniform pickling. Smaller slices are best, especially if your onion is big, because the rings are wider.
• Shake It Up: Give the jar a good shake every once in a while to redistribute the brine.
• Experiment: Feel free to tweak the brine by adding garlic, black peppercorns, herbs, or even other vegetables like jalapeños or carrots.

How to Make Quick Pickled Red Onions

Step One: Prepare the Onion

Slice the onions into thin slices using a mandolin or a sharp knife. Tightly pack the sliced onions into one large or two small jars.

Step Two: Prepare the Pickling Liquid

Mix vinegar, hot tap water, sugar, and salt in a bowl or large measuring cup. Whisk until fully dissolved. Pour the brine over the onions in the jar. It’s okay if the onions aren’t fully submerged; they’ll sink down.

Step Three: Marinate

Seal the jars and let the onions sit for 30 minutes to reach room temperature. You can enjoy the onions immediately or store them in the fridge to enhance their flavor.
