Kohlrabi and Apple Salad Recipe: Crisp Celery Twist With Sweet-Tart Balance

This kohlrabi apple salad transforms humble ingredients into a crisp, vibrant dish that balances sweet and tart flavors perfectly. 🍏 The secret lies in the texture contrast—crunchy kohlrabi, tender apples, and a bright dressing that keeps every bite fresh.

I developed this recipe after discovering kohlrabi at a local farmers market and realizing its potential as a salad star.

The preparation is straightforward yet rewarding: peel and shred the kohlrabi into thin ribbons (no peeling required if you prefer a rustic look), slice apples into matchsticks for crispness, and toss with a zesty vinaigrette.

For extra depth, roast the kohlrabi first—this caramelizes the edges and adds a subtle sweetness that complements the apples beautifully.

What you’ll end up with is a visually stunning salad that’s as satisfying to eat as it is to look at: bright green kohlrabi, crisp red apples, and a dressing that clings just enough to keep everything cohesive.

The celery twist adds a refreshing crunch, while a sprinkle of toasted nuts or seeds can elevate it to restaurant-quality.

Perfect for weeknight dinners, potlucks, or as a light lunch, this salad holds up beautifully for up to 24 hours in the fridge. Pair it with grilled chicken, fish, or serve it as a standalone vegetarian dish. Here’s how to bring it to life in your kitchen.

Ingredients for kohlrabi apple salad

Bright green kohlrabi meets crisp apples—just eight ingredients for a salad that pops with color and flavor.

Kohlrabi is the star here, so grab the freshest you can find—local farmers markets or well-stocked grocery stores like Whole Foods or Trader Joe's usually have the best. Look for firm, smooth bulbs with vibrant green skin; avoid any with soft spots or wrinkles. Honeycrisp or Fuji apples add that perfect sweet-tart crunch—Honeycrisp holds up best when sliced, but any crisp variety works. The celery? Organic stalks from the produce section keep things fresh and add that signature crunch. If you're feeling fancy, roast the kohlrabi first for a caramelized edge that takes this salad to the next level.

No Dijon mustard? Yellow mustard at half the amount works in a pinch, but trust me, the Dijon makes all the difference. Short on walnuts? Toasted pecans or almonds give a similar crunch. The dressing is the soul of this salad—balance is key. If your apples are extra tart, bump the maple syrup to 2 tbsp. For a spicier kick, add a pinch of cayenne to the dressing. And if you're prepping ahead, store the dressing separately until ready to toss—keeps everything crisp longer. The celery can be prepped a day ahead too, just wrap it tightly in a damp paper towel.

This salad keeps beautifully for 24 hours in the fridge, though the apples get slightly softer over time. Store the dressing separately and toss just before serving to maintain that perfect crunch. For extra freshness, add the dill and nuts/seeds right before eating. The dressing? It makes about 1/2 cup, so if you're doubling the salad, make a second batch. The roasted kohlrabi? Even better the next day—flavors meld perfectly. Portion into containers for meal prep, and you've got a week's worth of ready-to-eat lunches.

Step-by-step instructions for kohlrabi and apple salad

Here's how to assemble this vibrant, crunchy salad with a perfect sweet-tart balance.

Start by peeling the 2 medium kohlrabi using a vegetable peeler, removing just the outer skin. I like to use a mandoline set to ¼-inch thickness for even ribbons, but a sharp knife works too. Cut the kohlrabi into long, thin ribbons by holding the vegetable firmly and slicing at a slight angle—this creates more surface area for that satisfying crunch.

Next, core the 2 medium apples (Honeycrisp or Fuji work best) by slicing off the top and bottom, then cutting out the core in one clean piece. Slice the apples into matchstick-thin strips—about ⅛-inch thick. Toss them immediately with 1 tablespoon fresh lemon juice to prevent browning while you finish prepping. For the celery, thinly slice the 3 whole celery stalks on the diagonal for extra crunch and visual appeal.

In a small bowl, combine the 0.5 cup extra-virgin olive oil, 2 tablespoons apple cider vinegar, 1.5 tablespoons maple syrup, 1 teaspoon Dijon mustard, and 0.5 teaspoon salt. Whisk vigorously until fully emulsified—you should see tiny oil droplets disperse completely. The dressing should look silky and homogeneous.

Add the 1 tablespoon fresh lemon juice and 2 tablespoons chopped fresh dill, then give it one final whisk. Taste and adjust the balance: need more tang? Add a splash more vinegar. Too sweet? A pinch of salt or extra lemon juice will cut through it. Here's the thing—this dressing is the soul of the salad, so don't rush it.

In a large mixing bowl, combine the prepared kohlrabi ribbons, apple matchsticks, and celery slices. Pour the dressing over the vegetables and toss gently but thoroughly with your hands. I like to use a light touch here—just enough to coat everything evenly without bruising the delicate apple slices. The salad should look vibrant and inviting, with the colors popping against each other.

For texture contrast, sprinkle in the 0.25 cup toasted walnuts and 2 tablespoons pumpkin seeds right before serving. These add a satisfying crunch that balances the tender kohlrabi and apples. If you're feeling fancy, you can even toast the walnuts fresh in a dry skillet over medium heat for 2-3 minutes until fragrant.

Let the salad sit for 10-15 minutes before serving. This resting time allows the flavors to meld and the dressing to penetrate the vegetables fully. You'll notice the kohlrabi softens slightly while maintaining its crunch, and the apples develop a subtle sweetness that pairs beautifully with the tart dressing.

Serve immediately while the celery is still crisp and the apples retain their bright color. This salad holds up well for 2-3 hours in the fridge if stored in an airtight container, but the texture will be best when fresh. Pair it with grilled chicken, smoked salmon, or simply enjoy it as a light, refreshing meal on its own.
