Ingredients for the Salad
Here’s what you’ll need to make this creamy and delicious cucumber onion salad:
• Cucumbers: The main ingredient, providing a crisp and refreshing base. The cucumbers add a light texture that contrasts beautifully with the creamy dressing.
• Red Onion: Adds a bit of sweetness and sharpness to balance the creamy flavors. You can substitute with other types of onions, depending on your taste preferences.
• Sour Cream: The base of the dressing, providing richness and a slightly tangy flavor.
• Mayonnaise: Adds creaminess and depth to the dressing. If you’re looking for a lighter option, you can substitute with Greek yogurt.
• Fresh Dill: This herb gives the salad its distinctive, refreshing flavor. Fresh dill really elevates the salad, but dried dill can also be used as a substitute.
• White Pepper: Adds a subtle warmth and slight kick to the dressing.
• Flaky Sea Salt: Used as a garnish to enhance the flavors and add a slight crunch.
Alternative Ingredient Suggestions
If you’re missing an ingredient or need a variation to fit your dietary needs, here are some useful substitutions:
• Cucumbers: You can also use English cucumbers, which have a thinner skin and fewer seeds.
• Sour Cream and Mayo: For a lighter option, use Greek yogurt instead of sour cream and mayonnaise. This will give the salad a tangier flavor.
• Fresh Dill: If you don’t have fresh dill, you can substitute it with dried dill. Use about 2 teaspoons of dried dill for every 2 tablespoons of fresh dill. Other herbs like parsley, cilantro, or tarragon can also be used for a different flavor profile.
• Red Onion: If you don’t have red onions, feel free to use yellow or white onions, or even sweet Vidalia onions for a milder flavor. If you prefer no onions, simply omit them from the recipe.
Step-by-Step Instructions
Making this creamy dill cucumber onion salad is easy and straightforward. Here’s how you do it:
- Combine the Cucumbers and Onions: Slice the cucumbers and red onions thinly. Add them to a large mixing bowl.
- Prepare the Dressing: In a separate bowl, mix together sour cream, mayonnaise, fresh dill, and white pepper. Stir until smooth and well-combined.
- Toss the Salad: Pour the dressing over the cucumbers and onions. Use a large spoon to toss everything together, ensuring the cucumbers and onions are evenly coated in the creamy dressing.
- Refrigerate the Salad: Transfer the salad to the refrigerator and let it chill for at least 15 minutes. This allows the flavors to meld together.
- Garnish and Serve: Just before serving, sprinkle some flaky sea salt over the salad. You can also add more fresh dill or freshly cracked black pepper for extra flavor.

Tips & Tricks
- Release Extra Moisture: If you have extra time before serving, you can help the cucumbers release excess moisture by salting them. Place the sliced cucumbers and onions in a colander, sprinkle with salt, and let them sit for about an hour. This step will help prevent the salad from becoming too watery.
- Crisper Cucumbers: To ensure your cucumbers are crisp, consider half-peeling them (peeling in strips, leaving some skin on). Alternatively, you can fully peel them if you prefer.
- Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Keep in mind that the cucumbers will release some liquid over time, but this won’t affect the flavor.
Pairing Ideas and Variations
This creamy dill cucumber onion salad is a versatile side dish that pairs wonderfully with many meals. Here are some ideas for pairing:
- Grilled Meats: It’s perfect alongside grilled chicken, steak, or even burgers, adding a refreshing contrast to the richness of the meat.
- Vegan or Vegetarian Meals: This salad can complement a variety of plant-based dishes, such as roasted vegetables or quinoa bowls.
- Add-ins: For extra nutrition and color, consider adding chopped purple cabbage, or spice things up with finely chopped jalapeños for a little heat.
- Make-ahead Option: This salad can be prepared in advance, making it an excellent choice for meal prepping or potlucks.
