Tangy Asian Style Pickled Onions Ingredients

For the Pickled Onions
• Red onions (2 medium-sized) – Their natural sweetness pairs beautifully with the brine; yellow or white onions can be used for a lighter taste.

Step‑by‑Step Instructions for Tangy Asian Style Pickled Onions
Step 1: Prepare the Onions
Start by slicing two medium-sized red onions thinly using a mandoline slicer for precise, uniform thickness. This ensures even pickling and a delightful crunch in your Tangy Asian Style Pickled Onions. Once sliced, place them in a mixing bowl and set aside as you prepare the brine.
Step 2: Make the Brine
In a small saucepan, combine 1 cup of rice vinegar, 1/4 cup of sugar, 1 tablespoon of salt, and 1/2 cup of water. Heat the mixture over medium heat, stirring continuously until the sugar and salt dissolve completely, about 3-5 minutes. Once the brine is clear and well combined, remove it from heat and let it cool slightly.
Step 3: Combine
Pour the warm brine over the sliced onions in the mixing bowl, ensuring that the onions are fully submerged. This helps the flavors soak in deeply, creating the perfect Tangy Asian Style Pickled Onions. Allow the mixture to sit and cool for about 10 minutes, letting the onions absorb the briny goodness.
Step 4: Refrigerate
Transfer the onions and their brine into a clean, airtight jar. Seal it tightly and place it in the refrigerator. For optimal flavor infusion, let the onions pickle for at least one hour—though they’ll taste even better after sitting for a few hours or overnight. Enjoy the vibrant flavors!
