Quick and Easy Pickled Onions

Pickled Onions are hands down one of the best spring/summer condiments to have on hand. You can put them on sandwiches, tacos, or chop them in salads! I make a couple of jars at the start of spring so I have plenty on hand for fresh summer dishes!

I like to make a batched with red chili flakes for a spicy kick!

Whenever I make pickled onions, I tend to let them sit in the refrigerator for a day or two before I use them. I find doing that allows the onions to soften and absorb the vinegar.

Equipment

  • 1L Glass Jar with Lid

Ingredients

  • 2 Large Red Onions Sliced
  • 1 cup Apple Cider Vinegar
  • 2 cups Water
  • 2 tbsp Raw Sugar
  • 3 tsp Sea Salt
  • ½ tsp Red Chilli Flakes Optional

Instructions

  • Slice the red onions into thin slices. I like to slice them into full rounds, but you can also slice the onion in half to create a flat surface.
  • Add the onion slices into the clean jar. Pack in the onions tight.
  • In a small saucepan, add the water, vinegar, salt, and sugar. Heat on low until the sugar and salt have dissolved.
  • Pour the warm liquid over the onions in the jar. Use a skewer to poke through the jar to help remove air bubbles.
  • Place the lid on the jar and allow it to cool before placing it in the fridge.
  • For best results, leave the jar unopened for 2 days before consuming.
  • Keep in the fridge, keeps well for up to a month.
