Creamy Cucumber Salad

Last summer I found myself with an absurd amount of cucumbers from my dad's garden and started experimenting with cold salads. This creamy version became the one my friends started requesting for every barbecue. The way the cool cucumbers contrast with that tangy dressing is something special.

I made this for a July 4th cookout and watched three different people ask for the recipe. My cousin Sarah who claims to hate cucumbers went back for thirds. That is when I knew this recipe was a keeper for all summer gatherings.

Ingredients

• 2 large cucumbers: English or garden cucumbers work perfectly here just slice them thin so they really soak up that dressing
• 1 small red onion: The red onion adds this beautiful color and a mild sharpness that cuts through all the creaminess
• 3/4 cup sour cream: This is the base of your dressing full fat gives you the best texture but light works too
• 2 tablespoons mayonnaise: Just enough to add richness and help the dressing cling to every slice
• 1 tablespoon white wine vinegar: This brightens everything up and keeps the creamy elements from feeling too heavy
• 1 tablespoon fresh dill: Fresh dill makes such a difference here but dried works in a pinch
• 1 teaspoon sugar: Just a touch to balance the vinegar and bring out the natural sweetness of the cucumbers
• 1/2 teaspoon garlic powder: Gives you that savory backbone without any raw garlic harshness
• 1/2 teaspoon salt: Essential for drawing out moisture and amplifying flavors
• 1/4 teaspoon freshly ground black pepper: Adds a little warmth and depth

Instructions

Prep your vegetables:

Slice those cucumbers and onion as thin as you possibly can. A mandoline makes this effortless but a sharp knife and steady hand work perfectly fine.

Make the creamy dressing:

Whisk together your sour cream mayonnaise vinegar dill sugar garlic powder salt and pepper until you have something smooth and velvety. Taste it and adjust anything that needs tweaking.

Combine everything:

Pour that gorgeous dressing over your sliced vegetables. Toss so every single piece gets coated in that herby creamy goodness.

Let it hang out:

Pop it in the fridge for at least 20 minutes but honestly an hour is better. This is when the cucumbers start to soften slightly and really absorb all those flavors.

Serve it up:

Give it one last stir before serving and maybe scatter some extra fresh dill on top if you are feeling fancy.

This has become my go to for potlucks because it travels so well and everyone gets excited about something fresh and creamy. Last week I made a triple batch for a neighborhood block party and came home with an empty bowl.

Make It Your Own

Sometimes I swap in Greek yogurt for the sour cream when I want something lighter. The tang stays similar but it feels a bit more wholesome.

Serving Suggestions

This salad is the perfect partner for anything hot off the grill. Burgers chicken salmon even spicy sausages all love having this cool creamy element alongside.

Recipe Questions & Answers

→ How long should I chill the salad before serving?

Refrigerate for at least 20 minutes before serving. This resting period allows the cucumbers and onions to absorb the dressing flavors while maintaining their crisp texture. For even better flavor development, you can chill it for 1-2 hours.

→ Can I make this ahead of time?

Yes, this dish is excellent for meal prep. You can make it up to 2-3 days in advance. Store it in an airtight container in the refrigerator and give it a quick stir before serving. The cucumbers will release some liquid over time, but they'll stay delicious.

→ What can I substitute for sour cream?

Greek yogurt makes a wonderful lighter substitute for sour cream. It provides similar tanginess and creaminess with less fat. For a dairy-free option, try a plant-based yogurt or a cashew cream base.

→ Do I need to peel the cucumbers?

Peeling is optional and depends on your preference and the cucumber variety. English cucumbers have thin, tender skins that don't need peeling. For standard cucumbers with thicker skin, you might prefer to peel them or simply leave strips of skin for visual appeal.

→ How do I prevent the salad from becoming watery?

Salt the sliced cucumbers and let them sit in a colander for 15-20 minutes before combining with the dressing. This draws out excess moisture. Rinse briefly and pat dry before proceeding. This step is optional but helpful if you plan to store the salad for more than a day.

→ What herbs work well in this dressing?

Fresh dill is traditional and pairs beautifully with cucumber, but you can also try fresh parsley, chives, basil, or a combination. Dried herbs work in a pinch—use about one-third the amount of fresh herbs called for in the instructions.
