Ingredients You’ll Need
The beauty of this recipe is its simplicity. Here’s what you’ll need to get started:
Red Onion: The star of the show. One large red onion is perfect for a standard 16-ounce mason jar. Look for one that is firm and free of blemishes.
Vinegar: Apple cider vinegar is a fantastic choice for its mild, slightly fruity flavor. You can also use white wine vinegar or red wine vinegar for different flavor profiles.
Water: We’ll use equal parts water and vinegar to create a balanced brine that isn’t overly harsh.
Sweetener: A little bit of sugar balances the acidity of the vinegar. You can use granulated sugar or maple syrup for a refined sugar-free option.
Salt: Essential for flavor. I prefer using sea salt or kosher salt for the best results.
How to Make Pickled Red Onions (Step-by-Step)
Making your own Pickled Red Onions is a simple three-step process. Follow along, and you’ll have a delicious jar ready in no time.
Step 1: Prepare the Onion
First, slice your red onion. You can use a sharp knife or a mandoline for this. Aim for thin, uniform slices, about 1/8-inch thick. This thickness ensures they become tender but retain a satisfying crunch. Pack the sliced onions tightly into a 16-ounce glass jar or another heatproof container.
Step 2: Create the Brine
In a small saucepan, combine the apple cider vinegar, water, sugar, and salt. Bring the mixture to a gentle boil over medium-high heat, stirring until the sugar and salt have completely dissolved. This should only take a couple of minutes.
Step 3: Combine and Pickle
Carefully pour the hot brine over the sliced onions in the jar, making sure to submerge them completely. If needed, use a spoon to press the onions down. Let the jar sit at room temperature for about 20-30 minutes. You’ll see the onions transform into a vibrant pink color right before your eyes! Once cooled, secure the lid and transfer them to the refrigerator.
Tips for the Best Pickled Onions
While this recipe is straightforward, a few tips can ensure perfect results every time.
- Slice Evenly: Using a mandoline is the best way to get perfectly uniform slices. This helps the onions pickle evenly.
- Use a Glass Jar: Always use a glass jar for pickling. The acidic brine can react with metal or plastic containers.
- Press Them Down: Ensure all onion slices are fully submerged in the brine for proper pickling and food safety.
- Let Them Marinate: While they are ready to eat in 30 minutes, the flavor deepens and improves after a few hours in the refrigerator. I find they are best after 24 hours.
Recipe Variations
This base recipe for Pickled Red Onions is fantastic as is, but it’s also a great canvas for experimentation. Try adding some of these to the jar along with the onions:
- Spicy: Add a sliced jalapeño or a few red pepper flakes for a kick of heat.
- Herby: A sprig of fresh dill, thyme, or a few bay leaves can add a lovely aromatic quality.
- Garlicky: Toss in a few whole, smashed garlic cloves for an extra layer of flavor. They pair wonderfully with dishes like a classic homemade meatloaf.
- Peppercorns: Whole black peppercorns add a mild, pungent spice.

How to Store
Store your pickled red onions in an airtight glass jar in the refrigerator. Because this is a quick pickle recipe (not a true canning process), they are not shelf-stable. They will stay fresh and delicious in the fridge for up to 3 weeks.
Frequently Asked Questions About Pickled Red Onions
Yes, boiling the brine is a crucial step. It allows the sugar and salt to dissolve completely and helps the hot liquid slightly soften the onions, allowing them to absorb the brine faster for that ‘quick pickle’ effect.
When stored in a sealed jar in the refrigerator, these quick pickled red onions will last for up to 3 weeks. Their texture will soften slightly over time, but they will remain delicious.
Pickled red onions have a delicious tangy, sweet, and slightly salty flavor. The pickling process mellows the sharp bite of the raw onion, leaving you with a crisp, bright, and acidic crunch that enhances other foods.
Apple cider vinegar is a popular choice for its mild, slightly fruity flavor that complements the onions well. However, white wine vinegar, red wine vinegar, or even rice vinegar also work beautifully. You can choose based on your flavor preference!
The vibrant pink color comes from the reaction between the red onion’s natural pigments and the acidic vinegar. If your onions aren’t turning pink, ensure they are fully submerged in the brine. They will become pinker as they sit and marinate.
