Pickles Onions Ingredients
To make this pickled onion recipe, you really only need 5 basic ingredients; red onions, vinegar, sugar, salt and water. Then you can embellish as you like!
- Red onion: One small red onion, 3-4 inches in diameter.
- Vinegar: Using white vinegar will ensure the brightest clearest color, as well as the longest shelf life in the fridge. White vinegar is more concentrated than Rice Wine Vinegar, Apple Cider vinegar or Red wine vinegar– all of which will also work but check the recipe notes.
- Sweetener: White cane sugar offers up the clearest, cleanest-looking pickling liquid- but honey, maple syrup, coconut sugar or agave can all work too; however, know that they can “muddy” the color.
- Salt & Spices: Whole Spices add so much flavor here, depending on the direction you are going. Our favorites include fennel seeds, peppercorns, coriander seeds cumin seeds, caraway seeds, star anise, juniper berries, allspice berries, and peppercorns.
- Optional additions: Garlic, jalapeno slices, bay leaves, and fresh herbs.
How to make Pickled Onions
- Slice red onions thinly using a sharp chef’s knife or a mandolin.
- In a small pot, bring white vinegar, water, salt, sugar to a simmer. Add the onions and stir for 30 seconds. Turn the heat off, cool on the counter, then store in a clean jar and refrigerate!
- Pickled red onions will keep up to 3 weeks in the fridge.
Variations
Depending on what you are serving up for dinner, you can enhance the pickled onions with different whole spices, seeds and flavors!
- Mexican Pickled Onions: add whole cumin seeds and coriander seeds plus Mexican oregano to the pickling liquid. Thinly sliced jalapenos are nice too.
- Scandinavian Style: add fresh dill, caraway and peppercorns.
- Indian pickled onions: fennel seeds, coriander black mustard seeds, and fenugreek.

Ingredients
- 1 cup red onion, very thinly sliced
- 1/2 cup white vinegar (or use rice wine vinegar, apple cider vinegar or red wine vinegar – see notes)

Optional additions:
- garlic cloves, cut in half
- Bay leaves
- Fresh or dried herbs (oregano, cilantro, scallions, curry leaves, dill)

Notes
Vinegar: White vinegar is more concentrated than other kinds of vinegar. If subbing other vinegar like rice wine viniegar, apple cider vinegar or red wine vinegar, and you plan on keeping this for 3 weeks in the fridge, I would lower the water by 2 tablespoons. White vinegar will also ensure the clearest-looking pickling liquid and amplify the red onion’s color.
