Ingredients
- 2 medium red onions
- 4 cups boiling water
- 1/2 cup apple cider vinegar
- 1/2 cup water
- 3 tablespoons honey (or substitute sugar)
- 1/2 teaspoon salt
- 1 teaspoon peppercorns
Instructions
- Step 1: Peel the red onions and slice them thinly. Using a mandoline slicer is ideal for even slices, but a sharp knife works fine too.
- Step 2: Transfer the sliced onions to a medium-sized bowl.
- Step 3: Pour the boiling water over the onions and let them soak for at least 5 minutes to soften the sharpness.
- Step 4: Drain the onions in a colander and let them sit while you prepare the marinade.
- Step 5: In a medium bowl, combine apple cider vinegar, water, honey, salt, and peppercorns. Stir until the honey and salt dissolve completely.
- Step 6: Add the drained onions to the marinade and let them sit for at least 10 minutes so the flavors meld.
- Step 7: Transfer the pickled onions and marinade into jars with tight-fitting lids.
- Step 8: Chill the jars in the refrigerator until very cold before serving. They’ll develop even more flavor after a few hours.
Tips & Variations
- Use red wine vinegar or white vinegar instead of apple cider vinegar for a different tang.
- Add sliced jalapeños or garlic cloves to the marinade for extra heat and flavor.
- For sweeter pickled onions, increase the honey or sugar slightly.
- To ensure crisp onions, avoid soaking for much longer than 5 minutes in boiling water.
Storage
Store pickled red onions in airtight jars or containers in the refrigerator. They will stay fresh and flavorful for up to 2 weeks. Use a clean fork when removing onions to prevent contamination. Reheat is not necessary—serve cold or at room temperature.
