Ingredients for your cucumber salad with mayo and sour cream

Ingredient substitutions for this salad

• Mayonnaise: If you have an egg allergy or just aren’t a fan of mayo, you can leave it out completely. Add a little more sour cream, some Greek Yogurt, or even a bit of tahini to ensure the dressing is creamy enough.
• Sour Cream: You can use Greek yogurt and even kefir in place of sour cream. If you want to go dairy-free completely, look for a vegan sour cream at your local grocery store.
• Fresh Dill: If you don’t like the flavor of fresh dill, you can altogether omit this or, instead, use fresh fennel, tarragon, parsley, or cilantro.
• Red Onion: If you aren’t a fan of onions, you can leave these out completely, or if you can’t find any red onions, a sweet yellow onion will work well in its place.

Creamy dill cucumber salad FAQs

Can I make creamy cucumber and onion salad ahead of time?

Yes, you can, and I encourage it. The longer the flavors have to marry, the better! I like to refrigerate it, but only for a couple of hours. If you plan to make this a day in advance, note that cucumbers will start to get soggy and watery if refrigerated for too long.

In this case, it’s best to store cucumbers and onions in one airtight container and the creamy dill sauce in another. A little before you’re ready to serve, mix together.

If you have some extra time before serving, I would suggest adding the cucumbers to a bowl, adding some salt, and letting them sit in the refrigerator for awhile. This will ensure the cucumbers don’t release too much liquid within the salad. Your salad will be a lot creamier this way, but it’s not essential. If you want to get the salad on the table in 30 minutes, you can skip this step!

Can I add anything else to this recipe?

Of course! Adding in veggies like purple cabbage provides a beautiful pop of color, plus it’s delicious. If you want to spice it up a notch, try adding a couple of jalapeno slices for that kick of heat. Keep in mind that adding other vegetables will affect the total carb count.

How long can creamy dill cucumber salad sit out for serving?

You shouldn’t leave cucumber salad out for more than 2 hours. If possible, keep your cucumber dill salad on ice to keep it fresh longer.

I don’t like the flavor of dill. Do I have to use it?

No, although the dill really brings this recipe to life, chopped parsley or cilantro can be used as an alternative.

How do I store cucumber salad?

Always store leftovers in an airtight container. Creamy dill cucumber salad will last three days in the refrigerator. Do not freeze.
