Cucumber Onion Salad

This simple Cucumber Onion Salad makes for a refreshing side dish. A couple hours rest time means you can prep it ahead of time!

What Is Cucumber Salad?

This is a really simple and refreshing side dish of fresh cucumbers and onions that are marinated in a tangy vinegar mixture. There’s another kind of cucumber salad that is creamy and if that’s what you’re looking for, you can try my creamy Cucumber Dill Salad.

The ingredient list for this is pretty short. We’re using English cucumbers and sweet onions for this cucumber salad recipe. English cucumbers are great because they have thin skin that doesn’t need to be peeled. Some recipes use red onion instead of the sweet variety, so you can also try that, but stay away from harsher flavored white or yellow onions for this dish.

The vinegar mixture that the veggies soak in is simply vinegar, water, salt, and sugar. I like to sprinkle some fresh dill on top when serving, but that’s totally optional.

Why Marinate In A Baking Dish?

Lots of cucumber onion salad recipes I’ve seen have you marinating the veggies in a bowl in the fridge. While that does take up less space, it also means that only some of the vegetables are actually getting submerged in the mixture.

You may decide you’re okay with that, but I wanted the deliciously tangy flavor in each and every bite. That’s why I prefer to let my salad marinate in a large, shallow baking dish, like a 9×13 casserole dish.

Using a baking dish instead of a bowl to marinate the cucumbers and onion allows the vegetables to be in better contact with more of the seasoned vinegar, ensuring that every bite of cucumber and onion is flavorful.

Serving Cucumber Onion Salad

To serve this salad, use a slotted spoon to transfer the cucumbers and onions to a serving dish. You can drizzle over a few tablespoons of the vinegar mixture over the salad, but you don’t want the salad to continue to sit in the mixture, getting too soft. (You can use the remaining mixture to marinate other veggies or as the base of a salad dressing!)

This cucumber onion salad goes great alongside burgers and hot dogs or other grilled meats. Enjoy! – Christine xo
