Casa M Pickled Onions

At Casa M Spice Co® we love versatility and one of the most versatile toppings are pickled onions. They are one of those things that you always want to have on hand. With such easy preparation, there are no excuses not to have a couple of jars always waiting for you in your fridge. You’ll be amazed at how much they enhance any meal you are having.

For these pickled onions we used Casa M Spice Co® Chain Reaction® because its flavor profile perfectly compliments both the onion and the vinegar and gives the final product just the right amount of zest.

Typically, pickled onions are used in sandwiches, burgers, hot dogs, gyros, salads, tacos, but you can put them in basically anything you can think of. Soon we’ll show you an interesting and unique way we used these beautiful pickled onions, so be on the lookout! As always, from our table to yours... #SpiceConfidently #EssenceOfFlavor #ChemistryInTheKitchen #CasaMSpice

  • 1.

    There's no set rules here, but with two onions, one sweet and one red, you can throw all the red onions into one and all the sweet into another or you can mix them up and make both available in both jars.

  • 2.

    Prepare your onions, cut them in half, pull off the tough layer from each, and slice into 1/2 rings, then place them into the mason jars (however you decided — mix them up or not).

  • 3.

    In a small pot add the water, vinegar, Chain Reaction® or Uncontrolled Chain Reaction®, sugar, and salt and bring to a boil. Watch carefully as the liquid will evaporate quickly and affect the proportions.

  • 4.

    Once the liquid has come to a boil, carefully pour over the top of the onions in the mason jars all the way to the top. If you need more liquid, top off with added vinegar, then seal with the mason jar lid.

  • 5.

    Store these gems in the refrigerator and use on just about everything.


  • These pickled onions should be good up to a couple weeks. However, there are some things you can do to improve that shelflife, including sterilizing all items (utensils, jars, lids, cutting surfaces, and even the onions) before you start and keeping the jar sealed until you’re ready to use them.
