πŸ§… What You Will Need

All you need are a few simple ingredients to make this quick and easy pickled red onions.

1. Red Onions

Use red onions as they give bright pink color than the normal onions when dissolved in a vinegar solution. Very thinly slice them using either a sharp knife or a mandoline. Note that if you slice the onions thick, you will need to let them sit in the vinegar solution for at least twice the amount of time.

2. Vinegar

I prefer a combination of apple cider vinegar and white vinegar, but you can use just white vinegar instead. Apple cider vinegar gives a slightly sweet taste so there’s no need to add much sweetener.

Remember to keep the amount of vinegar almost similar to the amount of water, as vinegar provides a certain level of acidity that is essential for safe pickling.

3. Water

Dissolves salt and reduces the acidity of the brine.

4. Salt

Add about a teaspoon to balance the flavors.

5. Sugar

Balances the tartness of the vinegar. Sugar is most commonly used to pickle onions, but feel free to use honey or any other natural sweetener.

6. Other Optional Ingredients

These pickled onions will be delicious even if you use the basic recipe, but if you’d like to add more flavor then add garlic, cloves, black peppercorns, cinnamon stick, or red chilli flakes to the glass jar with sliced onions or you can boil these ingredients along with the vinegar solution.

The onions will be ready to serve when they are tender and pink in color. This could take about 10-12 hours or more, depending on the thickness of your onions. Once ready, enjoy them with almost any savory dish.

You can keep them tightly sealed in the fridge to last for up to 2-3 weeks.
