Ingredients to make Quick Pickled Red Onions

- Red onion – Of course, red onion is the main ingredient here! I have also used shallots for a little bit of a different taste.
- Water – A mix of half water and vinegar creates the brine. I like to use filtered water but tap water works just fine too.
- Vinegar – I use white vinegar because I always have a lot on hand and it is very budget-friendly. However, you could really use any type of vinegar and change up the flavor. Apple cider vinegar is another great option.
- Honey – A little sweetness balances out the flavors. I like to use honey, but you can use any type of sweetener you’d like, such as white sugar, maple syrup, or coconut sugar.
- Salt – I like a sea salt or a mineral-rich salt likeĀ Redmond Real Salt.Ā

Instructions to make Quick Pickled Red Onions

Step 1
In a small saucepan, add the water, vinegar, salt, and honey. Stir together and bring to a simmer.

Step 2
As the liquid heats, slice the onions. I prefer to use a mandoline slicer to get thin slices, but you can also use a sharp knife and cut the onion thinly. Add the sliced onions to a quart-sized mason jar.

Step 3
After the liquid comes to a simmer, remove from the heat and pour over the onions.

Step 4
Leave the onions on the counter until they reach room temperature, and then store in the fridge for 2-3 weeks. They are best after sitting for a few hours or overnight.

Tips for Quick Picked Red Onions
- Be sure to use a heat-safe container when making the pickled onions because you are pouring the hot brine over the onions. I find a quart mason jar to be the perfect size to fit the sliced onions and the brine.
- The onions are best the next day to give them time to soften and pick up all of the flavor from the vinegar, but if you are in a pinch they are still yummy right away.
