Total Time 10 minutes
Servings 16

Ingredients

  • 2 medium red onions (or 3 small ones)
  • 1 1/4 cup (300 ml) water
  • 1 1/4 cup (300 ml) white vinegar
  • 3 tbsp sugar of choice (see notes)
  • 1 tbsp sea salt
  • 1/4-1/2 tsp red pepper flakes (optional)

Instructions

  • You can watch the video in the post for visual instructions.
    In a saucepan, heat the water on the stove, turn off the heat before it starts simmering, set aside.
  • Slice the onions thinly (into rings or half-moons) with a knife, or use a mandoline. Transfer the sliced onions to a large (750 ml) mason jar (or use 2-3 smaller jars).
  • Add the salt, red pepper flakes (if using), sugar of choice, and white vinegar to the warm water. Give it a good stir and wait until the sugar and salt dissolve.
  • Pour the mixture into the mason jar, over the onions. Press them down gently with a spoon, close the lid, and transfer the jar to your fridge. You can try them after just 30 minutes, however, I prefer to let them marinate overnight for best results.
  • Enjoy on avocado toast, falafel, tacos, burgers, pizza, and more!

Notes

  • You can use organic cane sugar, coconut sugar, or a sugar-free sweetener like Erythritol.
  • Add other spices/herbs of choice, such as peppercorns, coriander seeds, mustard seeds, fresh ginger, fresh garlic. Read the blog post for many suggestions and serving ideas.
  • The total time doesn't include the marinating time.
