Instructions
Wash the cucumbers thoroughly, then slice them into thin rounds about 1/8-inch thick using a mandoline slicer or sharp knife. Leave the skin on for English or Persian cucumbers; peel regular garden cucumbers first.
Place cucumber slices in a colander, sprinkle with 1 tsp salt, toss to coat, and let sit for 15–20 minutes to draw out excess moisture. Press firmly and pat dry with paper towels before using.
Slice the red onion as thinly as possible, then soak the slices in a small bowl of cold water for 5–10 minutes to mellow the sharpness. Drain and pat dry before adding to the salad.
In a large mixing bowl, whisk together the sour cream, mayonnaise, white wine vinegar, and sugar until smooth. Stir in the minced garlic, black pepper, and chopped fresh dill, then taste and adjust seasoning as needed.
Add the drained and dried cucumber slices and the prepared red onion to the bowl with the dressing. Gently fold everything together until every cucumber slice is evenly coated.
Cover the bowl and refrigerate for at least 30 minutes to allow the flavors to meld. Stir gently before serving, drain any pooled liquid, and garnish with fresh dill sprigs.
Notes
Salt the cucumbers: Don't skip this step — salting for 15–20 minutes draws out excess moisture and prevents a watery, diluted dressing.
Use fresh dill: Fresh dill gives the brightest, most vibrant flavor. If substituting dried dill, use 1 tablespoon in place of 1/4 cup fresh.
Best cucumbers to use: English or Persian cucumbers are ideal — thin skin, few seeds, and a crisp texture. If using regular garden cucumbers, peel and seed them first.
Slice thin: Aim for 1/8-inch slices for the best texture and dressing coverage. A mandoline slicer makes this effortless.
Greek yogurt swap: Substitute full-fat plain Greek yogurt for the sour cream for a tangier, slightly lighter dressing.
Make it dairy-free: Use dairy-free sour cream and vegan mayonnaise for a fully plant-based version.
Make ahead: Slice and salt the cucumbers separately from the dressing; combine up to 1 hour before serving for the freshest texture. The finished salad keeps for up to 3 days in the fridge.
Storage: Store in an airtight container in the refrigerator for up to 3 days. Stir before serving and drain any liquid that collects at the bottom. Do not freeze.
Boost the flavor: Add a pinch of red pepper flakes for heat, crumbled feta for a Greek twist, or diced avocado for extra creaminess.
Serving tip: This salad doubles as a dip for pita chips or a topping for grilled salmon, lamb chops, or halibut burgers.
