Ingredients
Scale
1 large red onion, thinly sliced
1/2 cup apple cider vinegar
1/2 cup water
1 tbsp sugar
1 tsp salt
1/2 tsp black peppercorns
1/2 tsp crushed red pepper flakes (optional, for heat)
1–2 garlic cloves, smashed (optional)
1 sprig fresh thyme or 1/2 tsp dried thyme (optional)
Instructions
Thinly slice the red onion and place the slices into a clean jar or airtight container.
In a small saucepan, combine apple cider vinegar, water, sugar, salt, black peppercorns, red pepper flakes (if using), garlic, and thyme. Bring the mixture to a simmer over medium heat, stirring to dissolve the sugar and salt.
Once the sugar and salt are dissolved and the mixture is heated through, pour the hot liquid over the sliced onions in the jar, ensuring the onions are fully submerged.
Seal the jar with a lid and let it cool to room temperature. Once cooled, place the jar in the refrigerator.
Allow the onions to pickle for at least 1-2 hours before serving, though they will be best after 24 hours. They can be stored in the refrigerator for up to 2 weeks.
Notes
If you prefer a milder flavor, reduce the amount of vinegar or sugar.
Feel free to experiment with other herbs and spices, such as mustard seeds, cumin, or coriander, to add your personal touch.
