Ingredients You Need
To make perfect pickled red onions, you’ll need just a few simple ingredients:
- Red onions – thinly sliced for quick pickling and maximum surface area
- Vinegar (white, apple cider, or red wine) – the acidic base that preserves and brightens the onions
- Water – to balance the vinegar
- Sugar – a little sweetness to round the flavor
- Salt – enhances the flavor and helps mellow raw onion sharpness
- Optional aromatics – peppercorns, garlic, bay leaf, or fresh herbs
Here’s a basic version of the brine ratio:
- 1 large red onion, thinly sliced
- 1 cup vinegar
- ½ cup water
- 1–2 tablespoons sugar
- 1–2 teaspoons salt
- Optional: garlic cloves, peppercorns, herbs
How to Make Pickled Red Onions
1. Slice the Onions
Peel and thinly slice the red onions into rings or half‑moons, depending on how you prefer to serve them.
2. Prepare the Brine
In a small saucepan, combine vinegar, water, sugar, and salt. Warm over medium heat, stirring until sugar and salt dissolve.
3. Add Optional Flavors
For extra flavor, add a clove of smashed garlic, a few peppercorns, or a sprig of fresh herbs like thyme or oregano.
4. Pack the Jar
Place the sliced onions into a clean jar. Pour the warm brine over the onions, making sure they are fully submerged.
5. Cool & Refrigerate
Let the jar cool to room temperature, then seal and refrigerate. You can enjoy them in as little as 30 minutes, but they taste even better after a few hours.
How to Use Pickled Red Onions
Pickled red onions are incredibly versatile — here are some tasty ways to use them:
- Tacos & burritos – adds a burst of acidity and color
- Salads – perfect on green salads or grain bowls
- Sandwiches & burgers – cuts through rich, creamy flavors
- Charcuterie boards – brightens salty meats and cheeses
- Avocado toast or eggs – adds tang and crunch
- Grilled fish or chicken – pairs beautifully with smoky flavors

Tips for the Best Pickled Red Onions
- Use thin slices — they pickle faster and are more tender to eat.
- Warm brine is key — it infuses flavor efficiently and softens onions just right.
- Let them rest — they’re good after 30 minutes, but best after a few hours.
- Store properly — keep in the fridge for up to 2–3 weeks.
- Mix vinegars — try half apple cider and half red wine for a richer flavor.
Frequently Asked Questions
Can I use other types of onions?
Yes! White or sweet onions work too, but red onions give the best color and flavor contrast.
Do pickled onions lose their crunch?
A quick pickle is not as crisp as a raw onion, but they should still hold a pleasant bite. If they get too soft, reduce the soaking time or slice slightly thicker next time.
Can I can these for long‑term storage?
This recipe is intended for refrigerator pickles. If you want to can them shelf‑stable, follow a proper canning procedure with sterilized jars and pressure or hot‑bath canning guidelines.
