This salad turns humble zucchini into something crisp, zesty, and full of texture from toasted seeds. The mint and lemon dressing keeps every bite light, while the seeds add a nutty crunch that makes it feel satisfying enough for lunch.

You slice, salt, toss, and eat in about the time it takes to scroll a social feed, so it fits hot days when you avoid the stove. It also works with all kinds of main dishes, so you can bring it to a cookout and watch it quietly steal the spotlight from the burgers.

Ingredients You Need

Fresh produce

3 medium zucchini, very thinly sliced (use small, firm zucchini for best crunch)
1 small cucumber, thinly sliced (optional, adds extra hydration and crunch)
1 small red onion or 2 shallots, very thinly sliced
1 packed cup fresh mint leaves, roughly chopped
Zest of 1 large lemon (organic if possible, since you use the peel)

Seeds and crunch

3 tablespoons hulled sunflower seeds
2 tablespoons pumpkin seeds (pepitas)
1 tablespoon sesame seeds (white or mixed; I like toasted white sesame from Asian markets)
1 tablespoon chia or hemp seeds (optional, for extra nutrition and texture)

Lemon mint dressing

1 large lemon, juiced (about 3 tablespoons)
3–4 tablespoons extra-virgin olive oil (use your favorite fruity one; this dressing highlights the flavor)
1 teaspoon Dijon mustard (helps the dressing cling to the zucchini)
1 small garlic clove, very finely minced or grated
1–1½ teaspoons honey or maple syrup (balances the acidity; adjust to taste)
½ teaspoon fine sea salt, plus more to taste
¼ teaspoon freshly ground black pepper
Pinch of red pepper flakes (optional, for a gentle kick)

Pantry shortcuts & substitutions

Use bottled lemon juice only in a pinch; fresh lemon gives a brighter flavor.
Swap red onion with pickled onions from a jar if you want extra tang and zero chopping.
Replace honey with agave or maple syrup to keep the salad vegan.
Use pre-toasted seed mixes from the snack aisle to save time; just check for added salt and adjust seasoning.

Equipment list

Sharp chef’s knife or mandoline (for thin, even zucchini slices)
Large mixing bowl
Small bowl or jar with lid (for shaking the dressing)
Small skillet (for toasting seeds)
Microplane or fine grater (for lemon zest and garlic)
Tongs or salad servers

Quick Tips & substitutions

Slice zucchini very thin so it stays crisp yet soaks up the lemon mint dressing.
Sprinkle a little salt over sliced zucchini and let it sit 10 minutes, then pat dry to pull out excess moisture and boost crunch.
Toast seeds in a dry skillet over medium heat until fragrant, then cool before adding, so they stay crisp.
Swap zucchini with yellow squash or use half and half for color.
Use basil or flat-leaf parsley if you run out of mint, or mix herbs for a more complex flavor.
Add crumbled feta or goat cheese for extra richness, or use a vegan feta for a dairy-free option.
Replace olive oil with avocado oil if you prefer a milder flavor.
Skip red onion and use thinly sliced green onions if you want a softer onion bite.

How to Make Summer zucchini salad with seeds, mint and lemon dressing

Step 1: Prep and salt the zucchini

Wash the zucchini and trim the ends. Slice them very thinly into rounds or half-moons, using a sharp knife or mandoline. Place the slices in a large mixing bowl, sprinkle with a small pinch of salt, and toss. Let them sit for about 10 minutes while you prep the rest, then gently blot with a clean towel to remove excess moisture.

Step 2: Toast the seeds

Place a small dry skillet over medium heat. Add sunflower seeds, pumpkin seeds, and sesame seeds. Stir frequently until they turn lightly golden and smell nutty, about 3–5 minutes, then transfer them to a plate to cool. Add chia or hemp seeds after toasting, since they do not need heat.

Step 3: Mix the lemon mint dressing

In a small bowl or jar, add lemon juice, lemon zest, Dijon mustard, minced garlic, honey or maple syrup, salt, pepper, and red pepper flakes. Whisk or shake until the dressing looks emulsified and slightly thick. Taste and adjust with a bit more salt, sweetener, or lemon juice until it hits that bright, tangy-smooth balance you like.

Step 4: Build the salad base

Add the sliced red onion or shallots and cucumber (if using) to the bowl with zucchini. Scatter the chopped mint over the top. Pour about two-thirds of the lemon mint dressing over the vegetables. Toss gently with tongs until everything looks lightly coated.

Step 5: Add seeds and finish

Sprinkle the toasted seed mixture and any extra chia or hemp seeds over the salad. Toss again, then taste and add more dressing or salt if needed. If the salad tastes sharp, drizzle in a tiny bit more honey or maple syrup to round it out. Serve right away or chill for 10–15 minutes to let the flavors mingle.

Recipe Variations

Gluten-free: The base recipe already avoids gluten; just confirm your mustard and any seed mixes use gluten-free ingredients.
Vegan: Use maple syrup or agave instead of honey and skip any dairy add-ins.
Low carb: Skip the honey or maple syrup or cut it in half, and leave out the optional cucumber.
Extra protein: Add chickpeas, grilled chicken strips, or marinated tofu cubes.
Cheesy twist: Add shaved Parmesan, crumbled feta, or goat cheese.
Herb swap: Replace mint with basil, cilantro, or a mix of soft herbs.
Crunch boost: Add chopped toasted almonds, pistachios, or walnuts along with the seeds.

Ways to Serve Summer zucchini salad with seeds, mint and lemon dressing

Serve as a fresh side next to grilled chicken, shrimp, or tofu.
Pile it over cooked quinoa or farro for a light lunch bowl.
Spoon it into lettuce cups for a cool, crunchy snack.
Use it as a topping for avocado toast.

Storage Success

Store leftover Summer zucchini salad with seeds, mint and lemon dressing in an airtight container in the fridge. The zucchini softens slightly by the next day, but the flavors deepen and still taste bright and lemony. If the salad releases extra liquid, stir it and add a small handful of fresh seeds or herbs to bring back some texture. Eat leftovers within 2 days for the best crunch and flavor.
