Ingredients:

2 medium red onions (or 3 small ones)

1 1/4 cup water

1 1/4 cup white vinegar

3 tbsp sugar (of choice (see notes))

1 tbsp sea salt

1/4-1/2 tsp red pepper flakes (optional)

Instructions:

The process of making these delightful pickled red onions is wonderfully straightforward. It primarily involves preparing the onions, creating a simple brine, and then letting time do its magic. I find it’s best to prepare the onions first, ensuring they are sliced thinly so they pickle evenly and become wonderfully tender yet retain a slight bite. The thinner you slice them, the quicker they will pickle and the more delicate their texture will be.

Step 1: Prepare the Onions

Begin extract by peeling your red onions. I like to trim off just the very top and the root end. Then, slice each onion in half from root to tip. Place the flat side down and slice them as thinly as you can. A sharp knife is your best friend here. If you have a mandoline slicer, now is its time to shine! Aim for slices that are almost translucent. You can then separate the rings by gently pulling them apart. The goal is to have them thinly sliced and ready to absorb the pickling brine. Place all your prepared onion slices into a heatproof jar or a bowl. I prefer using a glass jar with a lid, as it makes storage easy. Ensure the jar is clean and sterilized if you plan to store them for longer periods. A clean jar is crucial for food safety and for the longevity of your pickles.

Step 2: Create the Pickling Brine

In a medium saucepan, combine the water, white vinegar, sugar, and sea salt. If you are using them, add the red pepper flakes now as well. Stir everything together gently. Place the saucepan over medium heat. We want to bring the mixture to a gentle simmer, just until the sugar and salt have completely dissolved. It’s important not to boil the brine vigorously; a gentle simmer is all that’s needed. Stir occasionally to ensure everything is well incorporated. The aroma as the brine heats up is already a promise of the deliciousness to come – a subtle sweetness with a hint of vinegar. Once the sugar and salt are dissolved, remove the saucepan from the heat.

Step 3: Combine Onions and Brine

Carefully pour the hot pickling brine over the sliced red onions that you have placed in your jar or bowl. Make sure that all the onion slices are fully submerged in the brine. You might need to gently press them down with a spoon or another utensil to ensure this. If using a jar, you can gently swirl it to help distribute the brine. The hot brine will start to soften the onions immediately, and you’ll notice a beautiful transformation in their color as they begin extract to turn a brighter, more vibrant pink. This is the start of the pickling magic!

Step 4: Cool and Steep

Once the onions are submerged, let the mixture cool down at room temperature. This is a crucial step for safety and for the texture of the onions. Do not put the hot jar directly into the refrigerator, as this can shock the glass and potentially cause it to break. Let it sit on your counter for at least 30 minutes to an hour, or until it has cooled down significantly. During this time, the onions will continue to absorb the flavors of the brine, and their texture will start to change from crisp to tender-crisp. This initial cooling period is where much of the flavor infusion begin extracts.

Step 5: Refrigerate and Allow to Pickle

After the mixture has cooled to room temperature, cover the jar tightly with a lid. Transfer the jar to the refrigerator. The magic truly happens in the fridge. For the best flavor and texture, I recommend letting them pickle for at least 2-4 hours. However, they are truly at their peak after 24 hours. The longer they sit in the refrigerator, the more the flavors will meld and deepen. You’ll notice the onions become more tender and their color will deepen further. Taste a slice after a few hours and then again the next day to experience the evolution of their flavor. Once they’ve reached your desired level of tangin extractess and tenderness, they are ready to be enjoyed!

Storage and Enjoyment

These pickled red onions will keep in the refrigerator for several weeks, becoming even more delicious with time. The brine itself becomes wonderfully flavored too, so don’t discard it! You can use it in salad dressings or other marinades. I love having a jar of these on hand at all times. They are perfect piled high on avocado toast, layered into burgers, sprinkled over a simple green salad for a burst of flavor and color, or served alongside grilled meats and fish. They also make a beautiful and thoughtful homemade gift if you package them nicely in a decorative jar!

Notes on Sugar:

The type of sugar you use can subtly affect the flavor. Granulated white sugar is standard and provides a clean sweetness. You can also experiment with:

Brown Sugar: Adds a richer, slightly molasses-like depth of flavor.

Maple Syrup: For a more complex, earthy sweetness. Adjust the amount slightly as it is more liquid than granulated sugar.

Honey: Offers a floral sweetness.

Whichever you choose, ensure it dissolves completely in the brine.

Conclusion:

So there you have it! This simple yet sensational pickled red onion recipe is a true kitchen game-changer. It’s incredibly forgiving, remarkably quick to make, and elevates even the most humble dishes with its vibrant color and tangy-sweet flavor.

Don’t be afraid to experiment with this foundational recipe! Consider adding a pinch of chili flakes for a spicy kick, a bay leaf for an extra layer of aroma, or even a sprig of fresh dill. I truly encourage you to give these pickled red onions a try – you’ll wonder how you ever lived without them. They’re a fantastic way to add a professional touch and a burst of flavor to your everyday meals.

Frequently Asked Questions about Pickled Red Onions:

How long do pickled red onions last?

Stored in an airtight container in the refrigerator, these pickled red onions can last for about 2-3 weeks. The vibrant pink color might fade slightly over time, but they’ll remain delicious and perfectly tangy for your culinary adventures.

Can I use a different type of onion?

While red onions are ideal for their beautiful color and balanced flavor, you can technically use other onions like white or yellow. However, they won’t achieve the same stunning pink hue, and their flavor profile will be slightly different. Red onions are definitely recommended for the best visual and taste experience.

What if I don’t have apple cider vinegar?

You can substitute apple cider vinegar with white grape juice vinegar or even plain white vinegar in a pinch. The resulting pickle might have a slightly different tang, but it will still be wonderfully delicious. Just aim for a vinegar with a similar acidity level.
