Thinly sliced red onion softened in a bright, tangy apple cider vinegar brine adds a necessary pop of acidity to almost any meal. The sharpness of the raw onion mellows quickly in the boiling water and vinegar mixture, resulting in a crisp, pliable texture that keeps well in the refrigerator for whenever you need a quick garnish.
Keeping a jar of these pickled onions on hand transforms everyday lunches and dinners. They provide a clean, zesty counterpoint to fatty meats like carnitas or brisket, brighten up a simple avocado toast, and add a satisfying crunch to grain bowls and fresh salads. The subtle sweetness from a touch of sugar balances the brine, making them approachable enough to pile onto a burger or fold into a deli sandwich.
Because they come together in just a few minutes of active prep, they are a practical staple for busy weeknights. Once the brine cools and the onions sit, they develop a distinct, neon-pink hue that looks as good as it tastes. Having a batch ready to go makes it easy to add a professional-looking finish to your cooking without any extra effort at mealtime.
