Ingredients You'll Need
Simple ingredients are the secret to this Quick Pickled Red Onions Recipe, but each one plays a crucial role in creating the perfect balance of flavor, color, and texture. From the sharpness of the red onion to the sweetness of grenadine or sugar, these elements come together effortlessly.
- 1 medium red onion: Provides that beautiful purple color and sharp bite that softens with pickling.
- ½ cup white vinegar: The classic acidic base that tangily preserves and flavors the onions.
- ½ cup water: Helps mellow the vinegar to keep the onions crisp and balanced.
- 2 tablespoons grenadine or white sugar: Adds essential sweetness that smooths out the acidity with a subtle fruity note if you choose grenadine.
- 1 teaspoon salt: Enhances all the flavors and keeps the onions perfectly seasoned.
How to Make Quick Pickled Red Onions Recipe
Step 1: Slice the Onion
Start by peeling your red onion and slicing it very thin. A mandoline slicer set to about 3mm thickness is perfect for ensuring even slices that will soak up the pickling liquid beautifully. Thin slices mean the onions pickle quickly and develop the best texture.
Step 2: Prepare the Pickling Liquid
Combine the white vinegar, water, grenadine (or sugar), and salt in a small saucepan. Heat until it just reaches a boil, stirring until the sugar or grenadine dissolves into a smooth mixture. This warm pickling liquid will infuse the onions with flavor in no time.
Step 3: Pickle the Onions
Place the sliced onions into a mason jar or a similar airtight container. Carefully pour the warm vinegar mixture over the onions, making sure they are fully submerged. Stir gently, then allow the jar to cool to room temperature before sealing and placing it in the refrigerator.

Make Ahead and Storage
Storing Leftovers
Your leftovers will keep beautifully in the refrigerator for up to two weeks. Just make sure the onions stay fully submerged in the pickling liquid to maintain their texture and flavor. They’ll deepen in taste the longer they sit, making them even more delicious over time.
Freezing
Freezing is not recommended for this Quick Pickled Red Onions Recipe because it will compromise the crisp texture and vibrant appearance. The onions will become soggy and lose their signature crunch upon thawing.
Reheating
Since these onions are served chilled or at room temperature, there’s no need to reheat them. If you prefer a slight warmth, just bring them to room temperature before serving, but avoid heating as it will soften their delightful snap.
FAQs
Can I use a different type of vinegar?
Absolutely! Although white vinegar is classic, apple cider vinegar or rice vinegar can also be used for a slightly different tang and flavor profile. Just keep the vinegar to water ratio the same for best results.
How long do quick pickled red onions last in the fridge?
They typically stay fresh and tasty for up to two weeks when stored properly in an airtight container with the onions submerged in the brine.
Can I make this recipe without sugar or grenadine?
Yes, but the sweetness balances out the acidity and roundness of the flavor. You can try using a natural sweetener like honey or skip it entirely if you prefer a more tart and sharp pickle.
What can I use to slice the onions if I don’t have a mandoline?
A very sharp chef’s knife will do the trick. Just take your time and slice as thinly as possible to ensure the onions pickle quickly and evenly.
Are there any variations to add extra flavor?
Definitely! You can toss in a few peppercorns, a clove of garlic, or even some fresh herbs like thyme to customize the brine and add complexity to your pickled onions.

Vegetables
- 1 medium red onion
Instructions
