Pickled Red Onions

If I’m being honest, I’ve never been a huge fan of pickled onions. Most pickled onions I’ve ever had always tend to be way too vinegary. However, these Pickled Red Onions are the perfect balance of tangy, sweet, and savory. These crisp pickled onions are perfect to top just about any dish. They are great on burgers, tacos, avocado toast, omelets, sandwiches, and more. Not only do they add so much flavor to other foods, they also add a pop of color with their redish-pinkish hue. Pickled onions are surprisingly easy to make with just a few simple ingredients. We always keep these in our fridge and will quickly become a staple in your kitchen too!

Are pickled red onions good for you?

Red pickled onions and other fermented vegetables contain a high amount of good probiotics and digestive enzymes. Which are great for your gut health and digestive system. In addition, red onions are a great source of vitamin B6 and folate as well as vitamin C.

How long do pickled onions last?

Pickled onions will last 3-4 weeks in the refrigerator. Keep them in a mason jar tightly closed.

Which vinegar is best for pickling?

White distilled vinegar is mostly used when pickling any vegetable. It has a tart acid taste and mild aroma. It’s a clear, colorless vinegar therefore it doesn’t alter the color of the food. Apple cider vinegar is also a great option for pickling because of it has more of a sweet and less sharp taste from white vinegar. Personally, I like to use a combination of both.

What you need to make Pickled Red Onions:

Ingredients:

• Red Onion
• Clove of Garlic
• Apple Cider Vinegar
• Distilled White Vinegar
• Pink Sea Salt
• Honey

Equipment:

• Small Saucepan
• Small Wide Mouth Mason Jar

How to Pickle Red Onions:

1. Thinly slice red onion into thin rings. Use hands to break each ring apart as much as possible or as much as you’d like. Mince garlic and add to mason jar. Place onion rings in mason jar over minced garlic. Set aside. 
2. In a small sauce pan combine apple cider vinegar, white distilled vinegar, salt, and honey. Place on stovetop and simmer on low heat for 5 minutes until all ingredients have dissolved and mixed together.
3. Pour vinegar mixture while it’s still hot into mason jar over onion and garlic. Press down on onion making sure it is submerged in the vinegar mixture. 
4. At this point let the onion sit on your kitchen counter for 1 hour until it cools down. Place lid on mason jar and close tightly. Refrigerate and leave in the fridge for 24-48 hours before serving. Serve over favorite foods and keep refrigerated for 3-4 weeks.

Tips and Substitutions:

1. Use a mandoline slicer if you have one- This will make the onions nice and thin. A sharp knife is just as fine too.
2. Substitute for other vinegars if you prefer- Apple cider vinegar has a sweetness to it that has a great contrast to the sourness white distilled vinegar has. You can use one vinegar of you prefer or rice vinegar or red wine vinegar. If you are using just one vinegar, substitute the other 1/2 cup for water.
3. Allow vinegar mixture to completely cool-off- Before you place onions in the fridge, they should be completely cooled-down. Refrigerating foods while they are still hot can cause harmful bacteria to be formed.
4. You can use other kinds of onions too- Red onions are best to serve raw which also makes them great for pickling. Plus they make such a pretty color when pickled. However, you can use any other kinds of onions for pickling like white or yellow onions.
5. Substitute for honey- You can use maple syrup.
