What To Serve With It
I love adding pickled red onions to tacos and burritos because they bring a tangy crunch that balances rich fillings. They’re also fantastic on salads and sandwiches, giving a bright pop of flavor that makes every bite more exciting. Once you try them, you’ll want to keep a jar handy for nearly everything.
Tacos and Burritos
When I’m loading up tacos or burritos, I always reach for something tangy and crisp to balance the richness—that’s where pickled red onions shine. They cut through the heaviness of melted cheese, savory meats, and creamy sauces, adding a bright pop of flavor. I love how their sharp acidity contrasts with smoky grilled fillings or spicy chorizo. Plus, their vibrant pink hue makes every bite look Instagram-worthy. Whether folded into a burrito or piled high on a taco, they bring a revitalizing crunch that ties everything together. Trust me, once you try them, you’ll never skip this topping again.
Salads and Sandwiches
Beyond tacos and burritos, pickled red onions are fantastic in salads and sandwiches, adding a zesty kick that wakes up every bite. I love tossing them into a simple green salad with avocado and feta—the tangy crunch balances the creaminess perfectly. On sandwiches, they’re a game-changer, cutting through rich flavors like roasted turkey or grilled cheese. Try them on a veggie burger, too; they’ll make it sing. Once, I ran out of lettuce and piled them on toast with hummus—instant upgrade! Trust me, once you start adding these to your meals, you’ll wonder how you ever ate without them.
