Ingredients

Red onions: These are the star of the show. Their natural sweetness and vibrant hue make them ideal for pickling. Slice them thin for the best texture and absorption.

Vinegar: I typically use white vinegar or apple cider vinegar. Both give that necessary tang and help preserve the onions. Apple cider vinegar adds a slightly fruity note.

Water: Used to dilute the vinegar slightly so it doesn’t overpower the onions. It also helps balance the brine.

Sugar: Just a bit to counteract the acidity of the vinegar. It brings out the natural sweetness of the onions.

Salt: Essential for flavor and for drawing out moisture from the onions.

Optional flavorings: Garlic, peppercorns, bay leaves, or red pepper flakes can be added depending on the mood or dish you’re prepping for.

How to Make Quick Pickled Red Onions

Step 1: Slice the Onions

Start by slicing your red onions very thin. This allows them to soften quickly and absorb the brine. A mandoline works great, but a sharp knife does the job too.

Step 2: Make the Brine

In a small saucepan, combine vinegar, water, sugar, and salt. Bring it to a light simmer just until the sugar and salt dissolve. If you’re adding spices or garlic, toss them in now to infuse the brine.

Step 3: Combine and Rest

Place your sliced onions into a clean jar. Pour the hot brine over the onions, making sure they’re fully submerged. Let them cool to room temperature, then refrigerate. They’ll be ready in 30 minutes, but the flavor intensifies after a few hours.

Recipe Variations and Possible Substitutions

This quick pickled red onions recipe is easy to customize. For a spicier version, toss in a few slices of jalapeño or a pinch of red pepper flakes to the brine. Craving more aromatics? Add smashed garlic cloves or a bay leaf. You can also try using rice vinegar for a milder, slightly sweet profile. White wine vinegar works beautifully, too. If you’re out of red onions, don’t worry—this method works with shallots, white onions, or even thinly sliced radishes.

Serving and Pairing Suggestions

Quick pickled red onions elevate everything they touch. Add them to burgers or sandwiches for a tangy crunch, or top tacos, nachos, and burritos for a burst of brightness. I love them with grilled meats, especially steak and chicken. They’re also amazing in grain bowls, pasta salads, or as a bold topper for avocado toast. Even breakfast gets better with a spoonful over scrambled eggs or breakfast wraps.

Storage and Reheating Tips

Store your pickled onions in a tightly sealed glass jar in the refrigerator. They keep well for up to three weeks. There’s no need to reheat them, and they actually taste better chilled as the flavors continue to deepen over time. Just make sure your onions are always submerged in the brine to maintain freshness.
