Pickled Onions

My absolute favorite condiment, something I always keep in the fridge, is pickled onions. Maybe it’s the tangy, sweet taste, maybe it’s the crunchy texture, or maybe it’s that beautiful pink color, I don’t know, but these are a kitchen staple. Made with just a few simple ingredients like raw apple cider vinegar, sea salt, and freshly squeezed lemon juice, these onions marinate in the fridge and make even the simplest dishes something special.

How do I eat pickled onions? Honestly, they’re so versatile and I love them so much, that I find endless ways. They brighten salads, add acid to sandwiches and wraps, and make my breakfast plate a real dream. I’ve even been known to eat them right out of the jar with a fork (and so has my three year old!). I like them with eggs or on anything spicy, on my Loaded Taco Sweet Potato Nachos or on my quick Greek Salad with Shrimp.

A lot of pickled onion recipes call for refined sugar, but I just don’t think you need it. A bit of lemon juice works great to take the edge off the sharp vinegar taste. I recommend using raw, unfiltered apple cider vinegar (like Bragg’s). And if you’re in a hurry, they can be made quickly, too. Just gently heat the vinegar and spices in a small sauce pan until it begins to simmer, then carefully pour the mixture into the jar, over the onions. They’ll be ready to eat in a snap!
