- 1 small red onion, thinly sliced
- 1/2 cup sour cream
- 1/4 cup mayonnaise
- 2 tablespoons white vinegar
- 1 tablespoon sugar
- 1 teaspoon dill weed

How To Make Grandma B’s Cucumber Salad Step by Step
- In a large bowl, combine the sliced cucumbers and red onion. Ensure they are evenly mixed for a consistent flavor in every bite.
- In a separate bowl, whisk together the sour cream, mayonnaise, white vinegar, sugar, dill weed, salt, and pepper until smooth and well blended.
- Pour the prepared dressing over the cucumber and onion mixture. Toss gently to coat all the vegetables evenly.
- Cover the bowl with plastic wrap and refrigerate for at least 30 minutes to allow the flavors to meld together.
- Before serving, give the salad a quick toss and adjust the seasoning if necessary. Serve chilled for the best taste and texture.

Storing and Prepping Your Salad
To store Grandma B’s cucumber salad, place it in an airtight container and refrigerate it for up to 2 days. While the flavors improve with time, the cucumbers may release some water — simply toss the salad again to redistribute the dressing.
This dish is not ideal for freezing due to the high water content of cucumbers and the cream-based dressing. To make it ahead, prepare the dressing separately and mix it with the vegetables just before serving.
A Brief History of This Dish
Variations of cucumber salad have been a staple in kitchens worldwide, thanks to their simplicity and refreshing ingredients. This creamy version with dill and vinegar hails from northern Europe, where such flavors are cherished for their balance and harmony.
Grandma B’s cucumber salad likely evolved from these traditions, blending classic techniques with a modern creamy twist to suit contemporary palates. The result is a timeless recipe that feels as fresh today as it must have decades ago.
Easy Ingredient Swaps and Substitutions
If you’re short on sour cream, Greek yogurt works as an excellent substitute, offering the same tang with a slight protein boost. For a lighter dressing, you can replace half the mayonnaise with plain yogurt, which retains creaminess while cutting down on fat.
Fresh dill can be swapped for 1/2 teaspoon dried dill if that’s what you have on hand. Additionally, apple cider vinegar can step in for white vinegar for a slightly sweeter, fruitier flavor profile.
Serving Ideas and Perfect Pairings
Grandma B’s cucumber salad complements grilled chicken or fish beautifully, as the creamy dressing offsets smoky flavors. Pair it with our lemon basil pasta salad for a vibrant, herbaceous side dish collection.
This salad also works well alongside sandwiches or wraps, cutting through the richness with its tangy freshness. For a simple summer meal, serve it with crusty bread and a light soup for a satisfying, balanced plate.
