Ingredients You’ll Need
These ingredients are straightforward but essential, each playing a key role in balancing tang, sweetness, and that signature pink hue. The red onion provides a crisp crunch and vibrant color, while the vinegar delivers the punchy acidity that pickling is all about. A little sweetness softens the edges and salt boosts all those flavors to perfection.
- 1 medium red onion: The star ingredient, sliced thinly for perfect pickling and crunch.
- 1/2 cup white vinegar: Brings sharp acidity that preserves and flavors the onions beautifully.
- 1/2 cup water: Lightens the vinegar and helps mellow the intense tartness.
- 2 tablespoons grenadine or white sugar: Adds subtle sweetness to balance the tanginess.
- 1 teaspoon salt: Enhances all ingredients and helps extract moisture from the onion for crispness.
How to Make Quick Pickled Red Onions Recipe
Step 1: Slice and Prep the Onion
Start by peeling your red onion and slicing it as thin as possible. I love using a mandoline set to about 3mm (1/8 inch) for perfectly even slices that soak up the pickling liquid beautifully. Place these slices directly into a clean mason jar, which will serve as your pickling vessel.
Step 2: Make the Pickling Brine
In a small saucepan, combine the white vinegar, water, grenadine (or sugar), and salt. Heat the mixture until it just starts boiling, stirring constantly to dissolve the sugar and salt completely. This step ensures that every layer of flavor blends seamlessly for that perfect tangy-sweet balance.
Step 3: Combine and Chill
Carefully pour your hot vinegar mixture over the sliced onions in the jar. Give it a gentle stir to coat every slice, then let it cool to room temperature. Once cooled, seal the jar with a lid and pop it in the fridge. While you can enjoy these pickled onions right away, they taste best after resting for a few hours or overnight, allowing the flavors to deepen and the texture to firm up.
How to Serve Quick Pickled Red Onions Recipe
Garnishes
Quick pickled red onions make a stunning garnish. Their bright pink color livens up tacos, burgers, grilled meats, or even simple bowls of rice and beans. Sprinkle a few slices over salads to add a zesty crunch that contrasts beautifully with creamy dressings or soft greens.

Pair them with roasted vegetables or grilled proteins for an acidic punch that cuts through richness. They’re fantastic alongside barbecue ribs, grilled chicken, or fried fish, lifting the whole meal with that fresh, tangy bite.
Creative Ways to Present

Make Ahead and Storage
Storing Leftovers
Once your pickled onions are made, keep them refrigerated in a sealed jar. They’ll stay fresh and flavorful for up to two weeks, giving you plenty of time to enjoy their zing in multiple meals without worrying about them going soggy or losing their crunch.
Freezing
Freezing pickled red onions isn’t recommended because it tends to ruin their crisp texture. The water contained in the onions expands when frozen and causes them to become mushy upon thawing, losing the delightful crunch that makes this Quick Pickled Red Onions Recipe so special.
Reheating
These pickled onions are meant to be eaten cold or at room temperature to retain their crunch and brightness. Warming them changes the texture and dulls their tangy flavor, so it’s best to serve directly from the fridge or after resting at room temperature.
FAQs
How soon can I eat the pickled onions after making them?
You can enjoy your Quick Pickled Red Onions Recipe right after they cool down, but for the best flavor and texture, letting them sit in the fridge for a few hours or overnight is ideal.
Can I use a different type of vinegar?
Absolutely! While white vinegar gives a classic tang and bright color, you can experiment with apple cider vinegar or red wine vinegar for a slightly different flavor profile. Just keep in mind that darker vinegars might change the color of your onions.
Is grenadine necessary? Can I just use sugar?
Grenadine adds a lovely fruity sweetness and deepens the pink color, but plain white sugar works perfectly fine too. Use whichever you have on hand or prefer.
Can I add spices to the pickling liquid?
Definitely! Feel free to toss in some peppercorns, garlic cloves, or bay leaves for extra flavor. This Quick Pickled Red Onions Recipe serves as a fantastic base that you can customize.
Will the onions stay crunchy after pickling?
Yes, if sliced thinly and refrigerated properly, they should maintain a satisfying crunch for at least a week. The quick pickling method preserves that delightful texture wonderfully.
