Creamy Cucumber and Red Onion Salad

Creamy Cucumber and Red Onion Salad is a cool, refreshing, and flavorful side dish that is perfect for warm days, family dinners, potlucks, and backyard barbecues. Crisp cucumber slices and slightly sharp red onion are coated in a smooth, tangy, and creamy dressing made with sour cream, mayonnaise, lemon juice, and a touch of Dijon mustard.

One of the best things about this recipe is its simplicity. You don’t need complicated ingredients or special cooking skills to make a delicious salad. With a little slicing, mixing, and chilling time, you can create a creamy side dish that pairs beautifully with grilled chicken, fish, sandwiches, burgers, and many other meals.

The secret to a great cucumber salad is removing some of the excess moisture from the cucumbers before mixing them with the dressing. This simple step helps keep the salad creamy instead of watery. After chilling in the refrigerator, the flavors blend together beautifully, creating a refreshing dish that tastes even better when served cold.

Ingredients

2 large cucumbers, thinly sliced

½ small red onion, thinly sliced

½ cup sour cream

¼ cup mayonnaise

1 tablespoon fresh lemon juice

1 tablespoon apple cider vinegar

1 teaspoon sugar

1 teaspoon Dijon mustard

Salt and black pepper, to taste

Fresh dill, chopped, optional for garnish

Instructions

Step 1: Prepare the cucumbers and onion

Wash the cucumbers thoroughly under cool running water. If the cucumber skin is thick or waxy, you can peel it completely or partially. Thinly slice the cucumbers into even rounds. A sharp knife or mandoline slicer can help create uniform slices.

Next, peel the red onion and slice it as thinly as possible. Thin slices work best because they blend easily with the creamy dressing and add a mild, slightly tangy flavor without overpowering the cucumbers.

Step 2: Remove excess moisture

Place the sliced cucumbers in a colander or strainer. Sprinkle them lightly with salt and gently toss to distribute the salt.

Allow the cucumbers to sit for approximately 10 to 15 minutes. The salt will help draw out some of their natural moisture. After resting, gently pat the cucumber slices dry with paper towels.

This step is especially helpful if you are preparing the salad ahead of time. Removing excess water helps the dressing stay thick, smooth, and creamy.

Step 3: Make the creamy dressing

In a large mixing bowl, add the sour cream, mayonnaise, fresh lemon juice, apple cider vinegar, sugar, and Dijon mustard.

Whisk everything together until the dressing is smooth and well combined. Season with salt and freshly ground black pepper to taste.

The sour cream gives the dressing a pleasant tang, while the mayonnaise adds richness and a silky texture. Lemon juice and apple cider vinegar bring brightness to the recipe, and the small amount of sugar helps balance the tangy flavors.

Step 4: Combine the salad

Add the prepared cucumber slices and red onion to the bowl with the creamy dressing.

Using a large spoon or spatula, gently toss everything together until all the vegetables are evenly coated. Try not to crush or break the cucumber slices while mixing.

At this point, you can taste the salad and adjust the seasoning if needed. Add a little more salt, pepper, lemon juice, or dill according to your personal preference.

Step 5: Chill the salad

Cover the bowl tightly and place it in the refrigerator for at least 30 minutes.

Chilling gives the cucumbers and onions time to absorb some of the delicious flavors from the dressing. The cold temperature also makes this salad extra refreshing.

For the best texture, serve the salad within a few hours of preparing it.

Step 6: Garnish and serve

Before serving, give the salad a gentle stir. Sprinkle freshly chopped dill over the top if desired.

Serve the Creamy Cucumber and Red Onion Salad cold as a refreshing side dish. Enjoy!

Tips for the Best Creamy Cucumber Salad

Choose fresh, firm cucumbers. Fresh cucumbers with firm flesh will provide the best crunch and texture.

Don’t skip the moisture-removal step. Cucumbers naturally contain a lot of water. Salting and drying them helps prevent a watery dressing.

Slice the vegetables evenly. Thin, even slices make the salad easier to eat and ensure that every bite has a good balance of cucumber, onion, and dressing.

Adjust the sweetness. If you prefer a more tangy salad, reduce or omit the sugar. If you enjoy a slightly sweeter dressing, add a little extra sugar.

Use fresh lemon juice when possible. Fresh lemon juice gives the dressing a bright and natural flavor.

Add dill just before serving. Fresh herbs can lose their bright appearance if they sit in the dressing for too long. Adding dill near serving time keeps the salad looking fresh.

Chill before serving. This salad tastes best when it has had enough time in the refrigerator for the flavors to blend.

Serving Suggestions

This creamy cucumber salad is a versatile side dish that works with many different meals. Try serving it alongside grilled chicken, roasted fish, burgers, sandwiches, or barbecue dishes.

It is also a wonderful addition to summer picnics, potlucks, and family gatherings. Because the salad is cool and refreshing, it provides a delicious contrast to warm and spicy foods.

For a simple lunch, enjoy a bowl of this salad with grilled chicken or a slice of crusty bread.

Frequently Asked Questions

Can I make this salad ahead of time?

Yes. You can prepare the salad a few hours before serving and keep it covered in the refrigerator. However, cucumbers continue to release moisture over time, so the salad is usually best enjoyed on the same day.

How do I keep cucumber salad from becoming watery?

The best way is to lightly salt the cucumber slices and allow them to rest before drying them with paper towels. This removes some of their excess moisture before they are mixed with the dressing.

Can I use Greek yogurt instead of sour cream?

Yes. Plain Greek yogurt can be used as a substitute for sour cream. It will give the salad a slightly different flavor and can create a lighter, protein-rich dressing.

What type of cucumber should I use?

Most varieties of cucumber will work well. English cucumbers are a popular choice because they generally have thin skin and fewer seeds. Regular cucumbers also work perfectly after washing and preparing them.

Can I leave out the red onion?

Absolutely. If you prefer a milder salad, you can reduce the amount of red onion or leave it out completely. You can also substitute a small amount of thinly sliced sweet onion.

How long does leftover cucumber salad last?

Store leftovers in an airtight container in the refrigerator and enjoy them as soon as possible. Because cucumbers release water over time, the texture and consistency of the dressing may change after sitting for too long.
