Add an extra boost of flavor to your meal with these quick pickled onions! They’re sweet, tangy and crunchy and take only 5 ingredients and 5 minutes to prep.
I recently added these pickled onions to a taco salad and instantly became obsessed. They were the perfect addition and added such great flavor. I’m going to make these all the time now and add them to all of my favorite meals!
I’m not actually a huge fan of raw onions, but when I first tried pickled onions it was a whole different story. For whatever reason, these taste SO much better. The marinade infuses an awesome flavor and creates a tangy, sweet and slightly crunchy onion. You will be adding these to everything after your first batch. They add an extra boost of flavor to any meal!
- Onion: Red onions work best and have the most flavor.
- Vinegar: I used a mixture of half apple cider vinegar and half white vinegar. You could use one or the other though.
- Sugar: Adding the sugar helps cut the acidity and gives it a slight sweet taste. Honey also works too.
- Salt: A small amount of salt is added for extra flavor.
- Water: The warm water helps soften the raw onions and takes the bite out.
How to pickle onions
These quick pickled red onions are so easy to make and only take 5 ingredients. They also only take about 5 minutes to prep and then you’ll just let them sit until they’re well marinated and the liquid has turned pink.
CUT. Start by cutting the onion into very thin slices with a sharp knife or mandoline. If the slices are too thick, they’ll take longer to soften and infuse with flavor. Aim for about 1/8 inch slices.
COMBINE. Mix together the remaining ingredients in a small bowl or glass jar and stir until dissolved. I prefer to use a glass jar so that I can easily mix and store them all in the same container.
MARINATE. Add the sliced onions into the jar or bowl and then cover with lid. Let the onions marinate in the mixture for 30 minutes before serving.
Once the onions are done marinating, cover the jar or bowl with a lid and store in the fridge. They will keep refrigerator for up to 2 weeks. You can even double the batch so that you have lots of extras on hand to add to any breakfast, lunch or dinner.
Thinly slice the onions. In order for them to marinate quickly, it’s important that the onions are very thinly sliced. They’ll soften up and gain more flavor faster. If you prefer thicker sliced onions, you’ll likely need to marinate them for 1-2 hours.
Add extra flavor. Feel free to add in extra spices like peppercorns, garlic, Italian seasoning and more.
Use warm water. Warm water helps to soften the onions, which in turn helps the vinegar soak into them quicker. If you want them to marinate quickly, make sure your water is warm.
