Step 1: Wash the cucumbers thoroughly. If using English or Persian cucumbers, you can leave the skin on. If using regular slicing cucumbers, peel them and remove seeds if desired. Slice the cucumbers into thin rounds, about 1/8 inch thick. A mandoline slicer works best for uniform slices.
Step 2: Place the sliced cucumbers in a large colander and toss them with 1 teaspoon of the fine sea salt. Let them sit for at least 20-30 minutes, or up to an hour. This step draws out excess moisture, ensuring your creamy cucumber salad recipe remains crisp and isn't watery.
Step 3: While the cucumbers are draining, prepare the creamy dressing. In a medium bowl, whisk together the sour cream, Greek yogurt, white wine vinegar, granulated sugar, fresh chopped dill, the remaining 1/2 teaspoon of salt, and black pepper until smooth and well combined. If adding thinly sliced red onion, stir it into the dressing now.
Step 4: After the cucumbers have drained, gently squeeze handfuls of them to remove as much liquid as possible. You'll be surprised how much water comes out! Pat them dry with paper towels to ensure they are as dry as possible before mixing with the dressing. This is a crucial step for the best creamy cucumber salad recipe.
Step 5: Transfer the squeezed and dried cucumber slices to a large mixing bowl. Pour the prepared creamy dill dressing over the cucumbers. Toss gently until all the cucumber slices are evenly coated with the dressing.
Step 6: Cover the bowl with plastic wrap and refrigerate for at least 30 minutes to allow the flavors to meld and the salad to chill thoroughly. For best results and maximum flavor, chill for 1-2 hours. Stir again before serving. Enjoy your refreshing creamy cucumber salad recipe!
