Ingredient Notes

  • Apple cider vinegar ​is the base of the pickling solution and is what gives these onions the best, tangy flavour. I prefer to make my quick pickled onions with apple cider vinegar as opposed to regular white vinegar because it is slightly less acidic and has a milder, sweeter flavour. If you prefer a sharper, more pungent flavoured quick pickled red onion recipe, feel free to use regular white vinegar. 
  • Black peppercorns add spiciness and compliments the acidity and subtle sweetness in the quick pickling liquid. 
  • A single bay leaf is key for adding a sweet and earthy aroma, and complex depth of flavour.
  • Salt adds savouriness that enhances the flavour and helps keep the onions crisp!
  • Agave adds a subtle sweetness that balances the acidity in the vinegar. No white sugar or granulated sugar needed! You can also substitute agave for maple syrup.

Prep Time 10 minutes
Marinade time 30 minutes
Total Time 40 minutes
Serves 10 people

Ingredients

  • 1 medium red onion
  • 1/2 tsp peppercorns
  • 1 bay leaf
  • 1 1/4 cups apple cider vinegar
  • 1/2 cup water
  • 1 tsp salt
  • 1 tbsp agave

Instructions

  • Slice the onions into very thin rings or half moons using a knife or mandoline. 
  • Add the sliced onions to a mason jar (I used a large 750ml jar) with peppercorns and one bayleaf. Set aside.
  • In a small saucepan, pour in the vinegar, water, salt and agave and bring to a low simmer. As soon as you starts to see bubbles turn off the heat (Alternatively, place the ingredients in a glass bowl, stir to combine and warm in the microwave for 1-2 minutes. Allow to cool for 1 minute).
  • Pour the vinegar mixture into the jar of onions. Gently press down on the onions with a spoon to make sure the onions are under the liquid. Screw on the lid.
  • Place the pickled onions in the fridge and let marinade for at least 30 minutes before using. (I like to leave them overnight so they go super pink. The longer you leave them the more vibrant they will be).
  • Serve these pickled onions as a topping for your favourite burgers, sandwiches, wraps, burritos and tacos.

Notes

These pickled onions will keep in the fridge for 2 weeks.
