TIPS AND TRICKS FOR MAKING PICKLED RED ONIONS

  • The most important part of making quick pickled red onions is to think the red onion very thinly. This helps them to absorb the vinegar and pickle them with that tangy flavor. I use a mandoline or you can use a very sharp knife to do this as well. 

  • You can substitute the sugar with honey or maple syrup if you want to use natural sugar instead of white sugar. 

  • If you are wondering if you can – can this recipe the answer is no. This is a quick pickling refrigerator recipe not a canning recipe. You will not want to use this as a canning recipe and put it in a water bath. With canning you want to always follow a recipe designed for canning to avoid botulism.

  • If you keep this in the fridge for up to the two weeks you will want to make sure the onions are submerged under the liquid as best as you can to keep them fresh and so they don’t dry out.

Here are some of my favorites:

Rice bowls are a great way to use these red onions. I love adding them to this Slow Cooker Cuban Pork Rice Bowl, Mediterranean Buddha Bowl, Chicken Shawarma Rice Bowl or this Mediterranean Baked Turkey Meatball Rice Bowl. 

Tacos is another great way to use pickled red onions. I love adding them to these Slow Cooker Shredded Beef Tacos, Easy Cod Fish Tacos, Tilapia Fish Tacos or these Southwest Breakfast Egg Tacos.

A few other ways I like to use them is to add them to this Chilaquiles Recipe, Slow Cooker Mexican Beef Brisket or this Mexican Zucchini.
