Crunchy Cucumber Zucchini Salad

Summer is when my garden gives me more zucchini and cucumbers than I know what to do with. Not that I’m complaining – these fresh veggies are perfect for light meals when it’s too hot to cook. My neighbors know they can count on me dropping off extras at their doorstep, but my favorite way to use them is in this simple cucumber zucchini salad.

I started making this salad a few years ago when I needed a quick side dish for our family BBQ. Now it’s become my go-to recipe whenever I want something cool and crisp. The best part? It takes just minutes to throw together, and the leftovers taste even better the next day. Plus, it’s a great way to get my kids to eat their vegetables without any fuss.

Whether you’re dealing with a garden overflow like me or just picked up some fresh veggies from the farmers market, this salad is exactly what you need. It’s light, refreshing, and pairs well with pretty much everything from grilled chicken to sandwiches.

What Kind of Cucumber Should I Use?

English cucumbers are the way to go for this salad, though regular slicing cucumbers can work in a pinch. English cucumbers (sometimes called hothouse or seedless cucumbers) have thinner skin, fewer seeds, and tend to be less bitter than their regular counterparts. They’re also typically wrapped in plastic at the store, which helps protect their thin skin. If you do end up using regular cucumbers, you might want to peel them and remove the seeds first since the skin can be a bit tough and waxy. Just remember that no matter which type you choose, look for cucumbers that feel firm and heavy for their size, with no soft spots or yellowing.

Options for Substitutions

This fresh salad recipe is pretty flexible and you can make several easy swaps if needed:

• English cucumber: Regular garden cucumbers work fine here – just peel them first and remove the seeds if they’re large. Persian cucumbers are another good option, just use 3-4 of them to match the amount.
• Red onion: You can swap in white or sweet onions, or even shallots for a milder flavor. If using shallots, you’ll need about 2 medium ones to match the amount.
• Apple cider vinegar: White vinegar or rice vinegar work well too. If using rice vinegar, you might want to reduce the sugar slightly since it’s naturally sweeter.
• Crushed red pepper flakes: Feel free to skip these if you don’t like heat, or try fresh cracked black pepper instead. You could also use a pinch of cayenne or a finely diced fresh jalapeño.
• White sugar: Honey or maple syrup can replace the sugar – start with 1 tablespoon since they’re sweeter than granulated sugar, and adjust to taste.

Watch Out for These Mistakes While Cooking

The biggest challenge when making cucumber zucchini salad is dealing with excess moisture – if you skip salting and draining your cucumbers and zucchini, you’ll end up with a watery salad that dilutes the tasty dressing. To prevent this, always salt your sliced vegetables and let them sit in a colander for at least 30 minutes, then pat them dry with paper towels. Another common mistake is cutting the vegetables too thick, which prevents them from properly absorbing the dressing – aim for thin, uniform slices (about ⅛ inch) using a sharp knife or mandoline for the best texture and flavor. For the most crisp and refreshing results, make sure to chill your salad for at least an hour before serving, allowing the flavors to meld together while maintaining that perfect crunch.

What to Serve With Cucumber Zucchini Salad?

This cool and crisp salad makes a perfect side dish for grilled meats – I especially love serving it alongside barbecued chicken or grilled salmon. The tangy apple cider vinegar dressing helps cut through richer main dishes, making it an excellent partner for hamburgers or pulled pork sandwiches. If you’re planning a Mediterranean-style meal, try pairing this salad with grilled lamb chops or kebabs, and maybe add some warm pita bread on the side. For a light lunch option, you can serve it alongside a quiche or frittata, letting the fresh vegetables balance out the richness of the eggs.

Storage Instructions

Keep Fresh: This cucumber zucchini salad tastes best when eaten within 24 hours of making it. Keep it in an airtight container in the fridge, where the flavors will continue to develop. The vegetables will stay crisp for the first day but will gradually soften as they marinate in the vinegar dressing.

Make Ahead: You can prep this salad up to 4 hours before serving – just combine everything and pop it in the fridge. The longer it sits, the more pickled the vegetables will become, which some folks really enjoy! If you want to prep further ahead, slice the veggies and store them separately from the dressing, then combine when you’re ready to serve.

Drain: If you have leftovers after a day or two, you might notice excess liquid in the container. Simply drain off the extra liquid before serving, and give the salad a quick toss to redistribute the seasonings. While it won’t be as crunchy as day one, it’s still good to eat for up to 3 days total.

Ingredients

• 1 tsp kosher salt (Diamond Crystal works wonderfully here)
• 1/2 cup apple cider vinegar
• 1 English cucumber (thinly sliced using a mandoline if possible)
• 1/2 small red onion (thinly sliced)
• 1/2 tsp crushed red pepper flakes (optional, for a little kick)
• 2 tbsp white sugar
• 1 medium zucchini

Step 1: Slice the Vegetables

Using a mandoline or a sharp knife, carefully cut the cucumber and zucchini into very thinly sliced rounds.

Aim to have about 2 cups of cucumber and 1½ cups of zucchini.

Ensure all slices are equally thin for uniform texture and flavor absorption.

Step 2: Combine and Salt the Vegetables

In a medium-sized bowl, toss the cucumber and zucchini slices together with thinly sliced onion and salt.

Mix thoroughly to ensure the salt is distributed evenly.

Allow this vegetable mixture to sit for 30 minutes to draw out excess moisture and intensify the flavors.

Step 3: Drain and Set Aside

After the vegetables have rested for 30 minutes, transfer the mixture to a colander to drain off the excess liquid.

Gently press to remove more moisture if necessary.

Return the drained veggie mixture to the bowl and set aside for the dressing.

Step 4: Prepare the Vinegar Mixture

In a separate bowl, combine apple cider vinegar, granulated sugar, and red pepper flakes.

Whisk or stir the mixture until the sugar has completely dissolved, creating a tangy and spicy dressing for your salad.

Step 5: Toss the Vegetables with Dressing

Pour the prepared vinegar mixture over the vegetable mixture.

Toss everything together thoroughly to ensure all the vegetables are evenly coated with the dressing for a harmonious flavor blend.

Step 6: Chill and Serve

Chill the salad in the refrigerator for at least 30 minutes to let the flavors meld and enhance.

Before serving, drain off any excess liquid once again to ensure the salad is not watery.

Serve cold and enjoy your refreshing veggie medley!
