These Homemade Pickled Red Onions are Awesome on Tacos, Hot Dogs or Burgers! Very easy to make as well in your own kitchen.
Recently I was at a party where they had a Mexican food truck and one of my friends noticed I didn’t have pickled red onions on my tacos. I told him that the tacos were super flavorful just the way they were, but he insisted I tried some with my next tacos. Well, he was right! So here is my Homemade Pickled Red Onions recipe.
I will admit that I only recently got into pickling. It’s always been on my list of things to master but it never seemed to bubble to the top. So making this recipe was the perfect opportunity for me to try pickling.
If you’ve never pickled onions or anything else for that matter, don’t be intimated. It’s very easy, probably easier than 75% of the recipes on this blog. And that is saying a lot since I pride myself in providing easy to make recipes.
With just a handful of ingredients, a mason jar, and this recipe you are well on your way to making your very own pickled red onions.

💭 How to seal jars
Using a ladle, fill sterilized mason jars leaving about 1/2 inch of headspace.
Remove any air bubbles by inserting a flexible spatula down the sides of the jars. Adjust headspace if necessary.
Wipe jar rims, place lids on jar and screw on bands finger tight.
Place jars in a large pot of boiling water for 20 minutes. Move jars to a cooling rack and let cool until the lids "pop". Do not tighten bands. Let jars cool for at least 4 hours. Test seal by pressing the center of the lid. It should not give. If it makes a popping sound, it has NOT sealed.
