Ingredients
- 1 large red onion
- 120 ml white vinegar
- 60 ml water
- 1 tablespoon granulated sugar
- 1 teaspoon kosher salt
- 1 teaspoon black peppercorns
- 1 clove garlic, thinly sliced
- 0.5 teaspoon optional red chili flakes
Directions
Step 1
Peel and thinly slice the red onion into rings or half-moons, depending on your preference.
Step 2
In a small saucepan or microwave-safe bowl, combine the white vinegar, water, granulated sugar, and kosher salt. Heat gently either on the stovetop or in the microwave until the sugar and salt dissolve completely. Do not boil.
Step 3
In a clean glass jar or bowl, layer the sliced red onions. Add the black peppercorns, sliced garlic, and optional red chili flakes for extra kick and flavor.
Step 4
Pour the warm vinegar mixture over the onions, ensuring they are fully submerged. Use a fork or the back of a spoon to press the onions down if needed.
Step 5
Cover the jar or bowl and let it sit at room temperature for 30 minutes to allow the onions to marinate.
Step 6
Once cooled, transfer the jar or container to the refrigerator. For best flavor, allow the onions to marinate for at least 1 hour before using.
Step 7
The marinated red onions can be stored in the refrigerator for up to 2 weeks. Enjoy them as a topping or side dish with your favorite meals!
