Ingredients

Scale

Onions

  • 4 large onions (yellow or sweet onions)

Boiling Liquid

  • 4 cups water
  • 1/4 cup soy sauce
  • 1/4 cup apple cider vinegar
  • 2 tablespoons brown sugar
  • 2 tablespoons olive oil
  • 4 cloves garlic (minced)
  • 1 tablespoon fresh ginger (grated)
  • 1 teaspoon black peppercorns
  • 1 teaspoon red pepper flakes (optional)

Garnish

  • Fresh herbs such as thyme or parsley (for garnish)

Instructions

  1. Prepare the Onions: Peel the onions and trim off the tops and bottoms. Leave them whole or cut them in half if preferred, depending on your texture preference.
  2. Make the Boiling Liquid: In a large pot, combine the water, soy sauce, apple cider vinegar, brown sugar, olive oil, minced garlic, grated ginger, black peppercorns, and red pepper flakes if using. Stir the mixture until the brown sugar is fully dissolved for an even flavor base.
  3. Cook the Onions: Bring the liquid to a boil over medium-high heat. Once boiling, add the prepared onions. Reduce heat to low, cover the pot, and let the onions simmer gently for about 30 minutes, or until they become tender and absorb the flavors.
  4. Serve: Remove the cooked onions from the pot and let them drain briefly. Serve warm and garnish with fresh herbs like thyme or parsley to add a fresh aromatic touch to the dish.

Notes

  • You can leave the onions whole or cut them in halves depending on your preference for serving size or cooking speed.
  • Red pepper flakes are optional and can be adjusted or omitted for less heat.
  • Fresh herbs such as thyme or parsley add a nice finishing flavor but can be substituted with other herbs like cilantro or chives.
  • This recipe works well as a savory side dish or as a flavor-packed addition to salads and grain bowls.
