- ½ teaspoon salt – Draws out the flavors of the onions and other ingredients.
- 1 teaspoon dried oregano – Provides an earthy, herbaceous note.
- ¼ teaspoon black peppercorns – Adds subtle warmth and spice.
- ¼ teaspoon fennel seeds (optional) – Introduces a mild licorice-like flavor for added complexity.

How to Make Balsamic Vinegar Pickled Onions
Making balsamic vinegar pickled onions is a straightforward process. Here’s how to do it step by step:
Step 1: Prepare the Pickling Mixture
In a small saucepan, combine the balsamic vinegar, water, sugar, and salt. Heat the mixture over medium heat, stirring occasionally until the sugar and salt are fully dissolved. Once dissolved, remove the saucepan from the heat and set it aside to cool slightly.
Step 2: Slice the Onions
Peel and thinly slice the red onions using a sharp knife or a mandoline. Uniform slices are key to ensuring even pickling.
Step 3: Layer the Ingredients
Place the sliced onions in a clean glass jar. Add the dried oregano, black peppercorns, fennel seeds, red pepper flakes, and fresh oregano if desired. Distribute these ingredients evenly for consistent flavor throughout the jar.
Step 4: Add the Pickling Liquid
Pour the warm vinegar mixture over the onions in the jar, ensuring they are fully submerged. Leave about ½ inch of space at the top of the jar to allow for expansion as the onions pickle.
Step 5: Seal and Cool
Close the jar tightly with a lid. Allow it to cool to room temperature before transferring it to the refrigerator.
Step 6: Chill and Serve
Refrigerate the onions overnight for the best flavor. If you’re short on time, you can enjoy them after 20 minutes of refrigeration, but letting them sit longer allows the flavors to deepen.
Tips for Success
1. Use Fresh Ingredients
Fresh red onions and high-quality balsamic vinegar are key to achieving the best flavor. Avoid pre-sliced or old onions, as they may lack the necessary crunch and sweetness.
2. Balance the Sweetness and Acidity
Feel free to adjust the sugar and vinegar ratios based on your preference. If you prefer a more tangy result, reduce the sugar slightly or increase the balsamic vinegar.
3. Don’t Skip the Submerging Step
Make sure the onions are fully submerged in the liquid to prevent spoilage and ensure even pickling.
4. Experiment with Spices and Herbs
This recipe is highly adaptable. Swap out the oregano for thyme, rosemary, or basil, or add a clove of garlic for a bold twist.
Recipe Variations
1. Citrus Infused Pickled Onions
Add thin slices of lemon or orange to the jar along with the onions. The citrus will lend a refreshing brightness to the pickling liquid.
2. Honey-Sweetened Onions
Swap out the sugar for honey or maple syrup for a natural sweetener. This works particularly well in dishes like grain bowls or roasted vegetable salads.
3. Extra Spicy Version
Increase the red pepper flakes or add a sliced jalapeño to the jar for a fiery twist.
4. Smoky Pickled Onions
Incorporate smoked paprika into the pickling mixture for a smoky, barbecue-inspired flavor.
