Ingredients
You only need a handful of simple ingredients to make this kitchen staple. Most are probably in your pantry right now!
- 1 large red onion: The star of the show! Red onions give us that beautiful pink color and a slightly sharper flavor that pickles wonderfully. Thinly sliced is key here!
- 1/2 cup apple cider vinegar: This is my go-to for pickled onions. It has a nice, mellow tang.
- 1/2 cup water: Helps to dilute the vinegar just enough so it’s not too harsh.
- 2 tablespoons sugar: Don’t skip this! It balances the acidity from the vinegar perfectly. You won’t taste sweetness, just balance.
- 1/4 teaspoon whole black peppercorns: Adds a subtle warmth and peppery note that makes them feel a little fancy.
- 1/4 teaspoon fine sea salt: Essential for flavor and helps with the pickling process.
- 1 bay leaf: Optional, but I love the subtle herby depth it adds. It’s a classic pickling spice for a reason!
How to Make It
Alright, let’s get pickling! You won’t believe how simple this is.
- First things first, grab a clean jar. A pint-sized Mason jar works perfectly.
- Now, slice up that beautiful red onion. The thinner, the better! I find slicing them about 1/8th inch thick is just right. You can use a sharp knife or a mandoline (carefully!).
- In a small bowl or a liquid measuring cup, whisk together the apple cider vinegar, water, sugar, and salt until the sugar and salt are dissolved. This is your magical pickling brine!
- Pop your thinly sliced red onion into the clean jar. Try not to pack them in too tightly, but fill it up! Tuck in the bay leaf and sprinkle in the whole black peppercorns.
- Pour the vinegar mixture directly over the onions in the jar. Gently press down on the onions if needed to make sure they are submerged in the liquid.
- Seal the jar tightly with a lid. Give it a little shake to distribute everything.
- Now, the hardest part: waiting! Let the jar sit on your counter for about 30 minutes at room temperature to start pickling. For the best flavor and color, transfer it to the fridge and let it chill for at least a couple of hours. They get even better after 24 hours!
Substitutions & Additions
Want to mix things up? Here are a few ideas:
- Vinegar Swap: While apple cider vinegar is classic, you can use white vinegar or white wine vinegar for a slightly different tang.
- Sweetener: Honey or maple syrup can be used instead of sugar, though they will impart their own flavor. Start with a little less and taste the brine!
- Spice It Up: Add a pinch of red pepper flakes for a bit of heat, or a clove of garlic (sliced) for garlicky pickled goodness. A pinch of mustard seeds or coriander seeds would also be lovely.
- Herbs: A small sprig of fresh dill or thyme can be added to the jar along with the onions.
Tips for Success
Making pickled onions is pretty foolproof, but a couple of tips can ensure they turn out perfectly every time:
- Slice Thinly: This helps the onions pickle faster and gives them a better texture.
- Use a Clean Jar: While not strictly required to be sterilized for quick pickles that live in the fridge, starting with a very clean, dry jar is always a good practice.
- Submerge the Onions: Make sure the brine covers the onions completely. This ensures even pickling and helps with preservation.
- Give Them Time (If You Can!): While they are quick pickled, their flavor mellows and the color becomes more vibrant the longer they sit. Letting them go overnight in the fridge is ideal.
How to Store It
Once your pickled onions are ready, store the sealed jar in the refrigerator. They will last for about 2-3 weeks (though honestly, mine never make it that long!). The flavor will continue to develop over the first day or two.
FAQs
- How long until they are ready? You can technically eat them after about 30 minutes on the counter, but they’ll be best after at least 2 hours in the fridge, and even better after 24 hours.
- What can I use them on? Oh, the possibilities are endless! Burgers, hot dogs, tacos (fish tacos especially!), salads, grain bowls, sandwiches, avocado toast, scrambled eggs, or alongside grilled meats.
- Do I need to heat the brine? For quick pickles like this recipe, nope! A cold brine works just fine and keeps things super simple.
- Can I use a different type of onion? You could, but red onions give you that signature vibrant pink color and pickle up with a great balance of sweet and sharp. White or yellow onions will work but won’t look as pretty and might have a different flavor profile.
