Cucumber and peanut butter salad tastes cool, crunchy, nutty, and a little tangy, and it comes together in about 15 minutes, which makes it perfect for busy weeknights, hot summer days, or anyone who loves a salty-sweet snack in salad form.

Ingredients You’ll Need

Main ingredients

Cucumbers:
- 2 large English cucumbers or 4–5 Persian cucumbers
- English cucumbers give fewer seeds and thinner skin. Persian cucumbers stay extra crunchy.
Red onion or shallot: thinly sliced, about ¼ cup
Fresh cilantro or flat-leaf parsley: small handful, chopped
Roasted peanuts: ¼ to ⅓ cup, roughly chopped, salted or unsalted

Peanut dressing ingredients

Creamy peanut butter: 3 tablespoons
- Use a natural peanut butter with just peanuts and salt if possible. Stir it well so the oil blends in.
Soy sauce or tamari: 1½ to 2 tablespoons
- Tamari works great if you need a gluten free option.
Rice vinegar or apple cider vinegar: 1½ tablespoons
Lime juice: 1 tablespoon, fresh if you can
Honey or maple syrup: 1 to 1½ teaspoons, to taste
Toasted sesame oil: 1 teaspoon
Garlic: 1 small clove, finely grated or minced
Fresh ginger: ½ teaspoon finely grated, optional but tasty
Chili flakes, chili crisp, or sriracha: to taste, optional
Water: 1–3 tablespoons to thin the dressing

Optional add-ins

Shredded carrot
Thinly sliced bell pepper
Thinly sliced green onion
Thinly sliced radish
Sesame seeds

Pantry shortcuts and brand notes

Use a good-quality creamy peanut butter like Skippy Natural or Jif Natural if you prefer a slightly sweeter, thicker dressing.
Use bottled lime juice in a pinch, but fresh lime gives brighter flavor.
Use pre-chopped peanuts or a bag of salted cocktail peanuts when you feel low on energy.

Equipment

Cutting board and sharp knife
Medium mixing bowl for the dressing
Large bowl for tossing the salad
Whisk or fork
Measuring spoons and cups
Vegetable peeler (optional, if you want to peel cucumbers)

Tips & Tricks

Salt cucumbers lightly and let them sit 5–10 minutes, then pat them dry so the salad stays crunchy and the dressing does not water down.
Slice cucumbers on a slight diagonal to increase surface area for the peanut dressing.
Thin the peanut dressing gradually with water until it coats a spoon but still feels pourable.
Taste the dressing before you toss the salad and adjust salt, acid, and sweetness so it hits your favorite balance.
Add chili in small amounts, taste, then add more so you do not accidentally turn it into a fire drill.
Toss the salad right before serving if you want maximum crunch, or toss ahead if you prefer a slightly marinated, softer texture.
Keep peanuts and extra herbs aside and add them right before serving so they stay crunchy and bright.
Double the dressing and keep it in the fridge for quick cucumber and peanut butter salad all week.

How to Make Cucumber and peanut butter salad

Step 1: Prep the cucumbers

Slice off the ends of the cucumbers. Cut them in half lengthwise, then into half-moons about ¼ inch thick. If the seeds feel very watery, scoop some out with a spoon.

Sprinkle a small pinch of salt over the sliced cucumbers in a colander. Let them sit 5–10 minutes, then pat them dry with a clean towel or paper towel.

Step 2: Mix the peanut dressing

In a medium bowl, add peanut butter, soy sauce or tamari, rice vinegar, lime juice, honey or maple syrup, sesame oil, garlic, and ginger. Whisk until the mixture looks thick and smooth.

Add 1 tablespoon of water and whisk again. Add more water, a little at a time, until the dressing reaches a pourable but creamy consistency. Taste and add more soy sauce for salt, more vinegar or lime for brightness, or a bit more honey for sweetness.

If you want heat, stir in chili flakes, chili crisp, or a small squeeze of sriracha. Whisk again so everything blends well.

Step 3: Combine the salad

Place the cucumbers in a large bowl. Add sliced red onion or shallot, chopped cilantro or parsley, and any optional veggies you like.

Pour about two-thirds of the peanut dressing over the cucumbers. Toss gently with tongs or clean hands so the dressing coats every piece. Add more dressing as needed until the salad looks glossy but not soupy.

Step 4: Add crunch and taste again

Sprinkle chopped peanuts over the top and toss lightly. Taste a cucumber slice and adjust with a pinch of salt, a squeeze of lime, or a bit more chili.

If you plan to serve it later, hold back some peanuts and herbs. Add them right before serving so they keep their crunch and color.

Step 5: Chill or serve

Serve the cucumber and peanut butter salad right away at cool room temperature. If you prefer it extra cold, cover the bowl and chill it for 20–30 minutes.

Give it a quick toss before serving, since the dressing can settle a bit at the bottom. Top with extra peanuts, herbs, and sesame seeds if you want it to look extra fancy.

What to Serve with it?

This cucumber and peanut butter salad pairs well with grilled chicken, baked tofu, or simple pan-seared fish for a light meal. You can spoon it over warm jasmine rice or brown rice for a quick rice bowl. It also tastes great next to veggie dumplings, spring rolls, or a simple egg fried rice.

If you want a snack plate, serve it with crisp lettuce leaves, carrot sticks, and rice crackers. Kids often enjoy it alongside plain noodles or steamed edamame.

Storage Options

Store leftover cucumber and peanut butter salad in an airtight container in the fridge for up to 2 days.
Keep extra dressing in a separate jar in the fridge for up to 5 days and stir it before using.
Add fresh chopped peanuts and herbs right before serving leftovers so they stay crunchy and bright.
Skip the freezer for this salad, because cucumbers turn mushy after freezing and thawing.
Eat leftovers straight from the fridge, or let them sit at room temperature for 10–15 minutes so the flavors soften and the dressing loosens.
