To pickle red onions quickly and easily, follow these general steps based on multiple reliable recipes:
Ingredients Needed
- Red onions (thinly sliced)
- Vinegar (white vinegar, apple cider vinegar, or a mix)
- Water
- Sugar (granulated, cane sugar, or alternatives like maple syrup or honey)
- Salt (sea salt or kosher salt)
- Optional: garlic cloves, peppercorns, or other spices for extra flavor
Basic Method
- Slice the onions thinly: Use a mandoline slicer or a sharp knife to get uniform thin slices for better pickling and texture
- Prepare the pickling brine: In a saucepan or microwave-safe container, combine vinegar, water, sugar, and salt. Heat the mixture until the sugar and salt dissolve completely. Typical ratios are about 1 part vinegar to 1 part water, with sugar and salt to taste (e.g., 1 tablespoon sugar and 1 teaspoon salt per cup of liquid)
- Combine onions and brine: Place the sliced onions in a jar or bowl. Pour the warm brine over the onions, ensuring they are fully submerged. You can add garlic cloves or peppercorns at this stage if desired
- Let them sit: Allow the onions to cool to room temperature, then cover and refrigerate. They can be ready to eat in as little as 30 minutes to 1 hour for quick pickling, though flavor improves if left overnight or up to several days. Pickled onions keep well in the fridge for up to 2 weeks or more depending on the recipe
Additional Tips
- Using a mandoline helps achieve thin, uniform slices that pickle evenly and look attractive
- You can vary the vinegar type for different flavor profiles, such as white wine vinegar, rice vinegar, or apple cider vinegar
- Adjust sugar for sweeter or more tangy pickles according to your taste
- Some recipes skip heating the brine and simply mix vinegar, water, salt, and sugar cold, then refrigerate for a lighter texture
