What Are Pickled Onions?
Pickled onions are onions marinated in a blend of vinegar, salt, sugar or honey, and assorted spices. This method softens the onions, infusing them with a tangy, sweet, and lively taste that enhances a variety of dishes. Not only are they flavorful, but pickled onions also last longer, helping you enjoy them over time and reduce food waste.
Ingredients
- Red Onion: This recipe uses one small red onion (about 3 ounces/86 grams), sliced into 1/4-inch thick half moons. While white or yellow onions are fine substitutes, red onions offer a beautiful color.
- Vinegar: Apple cider vinegar is preferred for its slightly fruity taste, but rice vinegar or white wine vinegar work too. Avoid balsamic vinegar for this recipe.
- Lime Juice: Add 2 tablespoons, equivalent to the juice from one medium-sized lime. Bottled lime juice is also suitable, offering a fresh citrus note.
- Honey: Honey provides a light, fruity sweetness. For a vegan alternative, use maple syrup or sugar.
- Salt: Essential for pickling, use 1/4 teaspoon of kosher salt or 1/8 teaspoon of regular table salt.
- Water: Helps to balance the vinegar’s tartness, making the pickling mixture milder.
Pro Tip: Customize your pickled onion with fresh herbs like thyme or rosemary, an orange peel, a garlic clove, or a bay leaf. Remember, the longer these additions sit in the mixture, the more pronounced their flavors will be. Remove them once the onions reach your desired flavor profile.
Recipe Variations
- Asian-Inspired Pickled Onions: Add rice vinegar, soy sauce, and some sliced ginger to the vinegar solution. This will give the pickled onions an Asian-inspired flavor profile.
- Mexican-Style Pickled Onions: Toss in some jalapeno slices, a hint of oregano, and cilantro to give your pickled onions a Mexican flair.
- Sweet and Spicy Pickled Onions: Add honey and a dash of crushed red pepper flakes to create a balance of sweet and spicy flavors.
- Mediterranean Pickled Onions: Incorporate a couple of bay leaves, some thyme, and a clove of garlic into your pickling mixture to give your onions a Mediterranean touch.
Notes:
Use your favorite herbs and spices. There are endless possibilities when it comes to herbs and spices, so feel free to experiment with your favorites.
Don’t be afraid to adjust the amounts. If you like your quick pickled onions more flavorful, add more herbs or spices. If you like them more sweet, add more honey or maple syrup.
How To Make Pickled Onions
These step-by-step photos and instructions help you visualize how to pickle an onion. See the recipe box below for ingredient amounts and full recipe instructions.
- Prepare the Onion: Peel a small red onion and slice it in half from top to bottom, cutting through the stem. Place the halves flat-side down on a cutting board and thinly slice them into 1/4-inch pieces. Place these slices in a small mason jar – a 2-cup size is ideal. Avoid using metal or plastic containers as metal can react with vinegar, and plastic may absorb flavors.
- Make the Pickling Liquid: In a small saucepan, combine water, vinegar, lime juice, honey, and salt. Heat the mixture over medium-high heat, stirring occasionally. Once it simmers and the honey dissolves completely, remove it from the heat.
- Pickle the Onions: Let the brine cool slightly. Then, carefully pour it over the onions in the jar, doing it gradually to avoid cracking the jar. Use a spoon to gently press and move the onions around, ensuring they are fully submerged in the liquid.
- Let It Sit and Store: Cover the jar and let the onions sit at room temperature for 30 minutes. After that, store them in the refrigerator. This recipe makes about 2/3 cup (70 grams) of pickled red onions.
Pro Tip: For the best flavor, keep your pickled onions sealed in an airtight jar in the fridge. They improve in taste after a few days!
Expert Tips
- Choose the Right Vinegar: The type of vinegar used in the pickling brine can impact the flavor of your pickled onions. While apple cider vinegar or white vinegar is a common choice, you can also experiment with red wine vinegar or even rice vinegar for unique taste variations. Just be sure to avoid balsamic or malt vinegar, as their strong flavors can overpower the onions.
- Customize the Flavor: Feel free to get creative with your pickling spices and seasonings. This is a basic pickled onions recipe so consider including other additions. Classic choices include peppercorns, mustard seeds, and bay leaves, but you can also add red pepper flakes for heat, fennel seeds for an anise flavor, or a pinch of cumin for earthiness. Adjust the sugar and salt levels in the brine to suit your personal taste preferences, creating a pickled onion recipe that’s uniquely yours.
- Slice the onions thinly, but not too thinly: The pickling process often thins out the onions a little and the moisture from the brine makes them soft. I like to slice my onions to 1/4-inch thickness.
- Use the right-sized jar for pickling: Since we are not heat processing these onions, you do not need to use a canning jar. Any jar with a lid or even a glass storage container will work. I use a 2-cup (1-pint) mason jar.
- Clean and dry your jar well before using it: You don’t want to introduce bacteria to the onion pickling process.

Love it! Two questions, can you use this same brine to pickle other veggies? Also can you use lemon instead of lime juice? Thanks Joanie 🙂
Yes to both questions. Lemon juice can be used instead of lime and you can use the brine to pickle other vegetables like cucumbers, carrots, cauliflower, and radishes.
I’m wondering if this recipe can be canned?
Would love to send some to my sister.
No. This recipe is a “refrigerator pickled onions” recipe and is not designed for canning in a water bath, and has not been tested for canning safety. I would recommend using a recipe specifically designed for canning instead.
These pickled onions are delicious.
I followed the recipe exactly as written.
Love the crunch and the liquid used is perfect
not too harsh.
My forever recipe.
Thank you Joanie 👍
I made these and LOVE them. Need to make more but was wondering if I can use the brine leftover from the first batch to make the second batch. Thoughts?
Yes, but I would recommend only using the brine one more time. Bring the brine to a boil again before using. The flavors will likely be diluted and you’ll have less liquid to work with. Either use fewer onions for your next batch or add additional vinegar, honey, and water.
Great recipe.
Delicious. Great on hot dogs and hamburgers. Salads and sandwiches too!
