If you’ve ever enjoyed a vibrant pink topping on a salad, taco or sandwich, chances are you’ve already met the humble pickled red onion. Tangy, crunchy and bursting with flavour, pickled onions have become a kitchen staple for good reason.
Not only do they add colour and zing to almost any meal, but they’re also incredibly easy to make at home using just a handful of ingredients. The best part? A single batch can elevate your lunches and dinners throughout the week.
Whether you’re looking to reduce food waste, experiment with homemade condiments or simply add more flavour to healthy meals, pickling your own onions is a great place to start.
Why Pickle Your Own Onions?
Store-bought pickled vegetables can often contain added sugars and preservatives. Making your own allows you to control exactly what goes into the jar while creating a fresher, more vibrant flavour.
Red onions are particularly popular because they soften beautifully during pickling while maintaining a satisfying crunch. Their naturally bold colour also transforms into the striking pink hue that makes dishes look instantly more appetising.
Pickled onions are delicious on:
- Salads
- Sandwiches and wraps
- Burgers
- Tacos and burritos
- Grain bowls
- Roasted vegetables
- Eggs and avocado toast
Easy Pickled Red Onion Recipe
Makes:
1 medium jar
Preparation Time:
10 minutes
Ingredients:
- 1 large red onion, thinly sliced
- 1 cup white vinegar or apple cider vinegar
- 1 cup warm water
- 1 tablespoon honey or maple syrup (optional)
- 1 teaspoon salt
- 1 teaspoon whole peppercorns (optional)
- 1 sprig fresh rosemary or thyme (optional)
Method:
Step 1: Prepare the onions
Thinly slice the red onion and place it into a clean glass jar.
Step 2: Make the pickling liquid
In a jug or bowl, combine the vinegar, warm water, salt and honey or maple syrup. Stir until the salt dissolves completely.
Step 3: Assemble
Pour the liquid over the onions until fully covered. Add peppercorns and herbs if desired.

Seal the jar and allow it to cool before placing it in the refrigerator.
The onions will start developing flavour within an hour, but they’re best after resting overnight.
Are Pickled Onions Healthy?
Pickled onions can be a nutritious addition to a balanced diet. Onions contain antioxidants and beneficial plant compounds, while the pickling process adds flavour without relying on excessive fats or sauces.
Because they are packed with flavour, a small amount can make healthy meals feel more exciting and satisfying. Choosing homemade versions also allows you to keep salt and sugar levels in check.
A Simple Way to Add Big Flavour
Healthy eating doesn’t have to mean bland meals. Sometimes the smallest additions can make the biggest difference. A jar of homemade pickled red onions can transform everything from salads to sandwiches, helping you enjoy more vegetables and experiment with new flavours.
With just a few minutes of preparation, you’ll have a colourful condiment ready to brighten your meals all week long. Give it a try—you may never go back to plain onions again.
