How to Make Quick Pickled Red Onions
Let’s dive into the cozy process of creating these delicious pickled onions together!
-
In a saucepan, combine the white vinegar, water, sugar, and salt. Heat gently until the sugar and salt have fully dissolved into the tangy mixture. You’ll start smelling the sweet aroma wafting through the kitchen!
-
While the vinegar mixture is warming, place the thinly sliced onions into a clean jar. I love using a mason jar as it makes for beautiful food storage too.

Once dissolved, pour the hot vinegar mixture over the onions, ensuring they’re fully submerged. If you’d like to add in those optional spices—like cumin or peppercorns—now’s the time!
-
Let the jar cool to room temperature before covering it tightly. After it’s cooled, refrigerate it for at least 30 minutes so the flavors meld together beautifully before serving.
Delicious Variations to Try
You can easily customize your quick pickled red onions to add a personal flair! Here are some fun twists:

- Herb-Infused: Toss in a few fresh sprigs of dill or thyme for a fragrant infusion that brightens up your pickles.
- Citrus Kick: Mix in a splash of lemon or lime juice for a zesty twist that uplifts the whole jar.
- Taste of the Southwest: Incorporate a teaspoon of smoked paprika for a deep, rich flavor profile that goes well with grilled meats.
