Ingredients

  • 1 red onion thinly sliced (about ⅛-inch thick)
  • 1 cup vinegar use apple cider vinegar, red wine vinegar, rice vinegar, or distilled white vinegar.
  • 1 teaspoon salt
  • 1 teaspoon ground black pepper for a spicy version use ½ teaspoon of red pepper flakes instead
  • 2 tablespoon sugar you can use honey, brown sugar, or maple syrup instead. If you are on a keto diet, use a sugar-free sweetener.

Instructions

    Cup of Yum
  1. In a microwave-safe container, heat the vinegar, sugar, salt, and pepper for about 2-3 minutes in the microwave or until hot. Or, heat the mixture in a pan over high heat on the stovetop until just beginning to boil.
  2. Place thinly sliced red onions in a 16-24 ounce glass jar or glass container.
  3. Pour pickling liquid on top of onions, close lid tightly, shake the jar, and let marinate at room temperature for at least 30 minutes.

Notes

  • If you don’t plan on serving them right away, make sure the jar is cool before storing in the fridge for up to 2 weeks. The longer they soak, the softer, sweeter, and pinker in color they’ll become!
