Ingredients You’ll Need

Every great dish begins with a handful of ingredients that shine on their own while harmonizing beautifully together. For Cucumbers and Onions in Vinegar, each element plays a crucial role—from the crisp crunch of cucumbers to the gentle sweetness of onions, and the tangy zing of vinegar that ties everything into a delightful melody of flavors.

Distilled white vinegar or white wine vinegar: Adds the essential tang and acidity that awakens the palate.
Very warm water: Helps dissolve the salt and sugar evenly to create a smooth marinade.
Sugar (optional): Balances the sharpness of vinegar with a subtle sweetness.
Table salt or Kosher salt: Enhances flavors and helps the cucumbers soften slightly for ideal texture.
Large cucumbers or English cucumber: The star of the dish offering cool crunch and freshness.
Sweet onion slivers: Bring a mild, aromatic sweetness that complements the acidity perfectly.
Freshly ground black pepper (optional): Adds a hint of spice and an extra dimension of flavor.

How to Make Cucumbers and Onions in Vinegar

Step 1: Prepare the Vinegar Mixture

Start by whisking together the vinegar, very warm water, sugar if you’re using it, and salt in a medium bowl. This combination will form the vibrant marinade that brings zing and balance to your cucumbers and onions. Warm water helps dissolve the salt and sugar completely, ensuring every slice gets coated evenly with flavor.

Step 2: Peel and Slice the Cucumbers

Next, peel your cucumbers if they have a thick or waxy skin to avoid bitterness. If your cucumbers are large, you might want to remove the seeds, which can be a little watery. If you’re using English cucumbers, you can skip peeling and seeding as they’re tender and mild. Slice them thinly, between 1/8 to 1/4 inch thick, to create the perfect texture that soaks up the marinade without becoming soggy.

Step 3: Combine Cucumbers and Onions with Vinegar Mixture

Place the sliced cucumbers and sweet onion slivers into the bowl with the vinegar marinade. Stir gently to make sure everything is evenly coated. The onions add sweetness and a bit of crunch, balancing the crisp cucumbers and sharp vinegar beautifully.

Step 4: Marinate and Chill

Cover your bowl and place it in the fridge for at least two hours. This is the magic step where the cucumbers and onions soak up all those fantastic flavors. The longer you let them marinate, the more intense and delicious the dish becomes. Before serving, give everything a gentle stir and season with freshly ground black pepper if you like a bit of spice.

How to Serve Cucumbers and Onions in Vinegar

Garnishes

Simplicity is key when garnishing this dish. A sprinkle of fresh dill or a few chopped fresh herbs like parsley or chives can elevate the salad with vibrant color and complementary flavors. A light dusting of black pepper adds a finishing touch that wakes up the palate without overpowering the refreshing qualities of the cucumbers and onions.

Side Dishes

Cucumbers and Onions in Vinegar is a versatile side that pairs beautifully with grilled meats, sandwiches, or even light fish dishes. Think grilled chicken, BBQ ribs, or a soft sandwich — the vinegar’s brightness cuts through rich or smoky flavors perfectly, giving you balance and brightness with every bite.

Creative Ways to Present

Want to impress your guests or just have fun with this classic? Serve the salad in a hollowed-out cucumber bowl, or layer it beautifully in a clear glass jar or bowl to show off the vibrant layers of white, green, and pale purple. You can also serve it chilled on a bed of mixed greens to add an extra crunch or toss it with a bit of fresh mint for an unexpected twist.

Make Ahead and Storage

Storing Leftovers

Keep any leftovers in an airtight container in the fridge. The flavors will continue to deepen as they sit, and your Cucumbers and Onions in Vinegar will stay fresh and crunchy for up to three days. Just give everything a quick stir before serving again to refresh the marinade coating.

Freezing

This dish is best enjoyed fresh or chilled and does not freeze well. Freezing will cause the cucumbers to lose their crispness and release a lot of water, making the texture mushy and less enjoyable. Stick to making just enough or storing it in the fridge for the best experience.

Reheating

No reheating necessary here! Cucumbers and Onions in Vinegar are meant to be served cold, as a refreshing, crunchy salad. Serving it chilled is part of the charm that makes this simple dish so wonderfully satisfying.

FAQs

Can I use other types of vinegar?

Absolutely! While distilled white vinegar or white wine vinegar is traditional and provides a clean, balanced acidity, you can experiment with apple cider vinegar or rice vinegar for a slightly different flavor profile. Just adjust the quantity to keep the acidity pleasant.

Do I have to peel the cucumbers?

Not always. If you’re using smaller or English cucumbers, you can leave the skin on for extra texture and nutrients. For larger cucumbers with thicker skin, peeling helps remove bitterness and makes the salad more tender.

Can this dish be made ahead of time?

Yes! In fact, the flavors deepen and improve after resting for a few hours or overnight in the fridge. Just be sure to keep it chilled and covered for best results.

Is the sugar necessary?

Sugar is optional but recommended to balance the acidity of the vinegar with a touch of sweetness, making the salad more harmonious. You can easily leave it out or reduce it to suit your taste.

What can I add to customize this recipe?

Feel free to add sliced fresh herbs like dill or parsley, sprinkle some red pepper flakes for heat, or toss in a splash of olive oil for richness. This recipe is a fantastic base that welcomes your creative flair.

Description

A refreshing and simple side dish of cucumbers and onions marinated in a tangy vinegar dressing. Perfect for summer picnics, barbecues, or as a crisp accompaniment to your favorite meals.

Ingredients

Scale

Vinegar Mixture

1/3 cup distilled white vinegar or white wine vinegar
1/4 cup very warm water
1 teaspoon sugar (optional)
1 teaspoon table salt (or 1 teaspoon Kosher salt)

Main Ingredients

2 large cucumbers (or 1 large English cucumber, about 2 cups sliced)
1/2 cup sweet onion slivers (about half of a small onion)
Freshly ground black pepper (optional)

Instructions

Prepare the vinegar mixture: In a medium-sized bowl, whisk together the vinegar, very warm water, sugar (if using), and salt until the sugar and salt dissolve completely, creating a balanced tangy-sweet brine.
Prepare the cucumbers: Peel the cucumbers if they have a thick skin. For large cucumbers, remove the seeds to avoid excess moisture and bitterness. If using English cucumbers, peeling and seeding are not necessary due to their thin skin and mild flavor.
Slice and combine: Slice the cucumbers into 1/8 to 1/4-inch thick pieces. Add the sliced cucumbers and the sweet onion slivers directly into the vinegar mixture. Gently stir to coat all pieces evenly.
Marinate: Cover the bowl and refrigerate for at least 2 hours to allow the cucumbers and onions to soak up the flavors. The longer they marinate, the more intensely flavored they become.
Serve: Use a slotted spoon to serve the marinated cucumbers and onions. Optionally, sprinkle freshly ground black pepper over the top to add a mild spice and enhance the flavor.

Notes

Using white wine vinegar offers a milder flavor compared to distilled white vinegar.
Peeling and seeding large cucumbers helps minimize bitterness and excess water in the dish.
The sugar is optional; adjust to taste if you prefer a sweeter or more acidic pickle.
Marinate longer than 2 hours for more pronounced flavors, up to overnight.
This side dish pairs well with grilled meats and sandwiches.
