Ingredients for apple celery walnut salad
Sweet apples, crisp celery, and toasted walnuts make this salad shine in minutes.
| Ingredient | Amount | Notes |
|---|---|---|
| Honeycrisp Apples 🍎 | 2 medium | Thinly sliced, lemon water soak |
| Celery Stalks 🧅 | 3 whole | Thinly sliced, crisp variety |
| Walnuts 🥜 | 1 cup | Toasted, roughly chopped |
| Dijon Mustard 🥬 | 1 tbsp | High-quality for tang |
| Extra-Virgin Olive Oil 🫒 | ½ cup | Fruity, not bitter |
| Apple Cider Vinegar 🍶 | 2 tbsp | Balsamic works too |
| Granulated Sugar 🍚 | 1 tbsp | Light brown sugar optional |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Fresh Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
| Fresh Parsley 🌿 | ¼ cup | Chopped, for garnish |
| Lemon Zest 🍋 | 1 tsp | From 1 lemon |
| Ground Black Pepper 🌶️ | ¼ tsp | Freshly ground |
The apples are everything here—Honeycrisp or Fuji are perfect, but any crisp variety works. Toss slices in cold water with a splash of lemon juice to keep them bright. Whole Foods or Trader Joe's usually have pre-washed apples, which saves time. Celery should be firm and white—avoid the yellowed ends. Walnuts toast in 5 minutes in a dry pan over medium heat—watch them like a hawk so they don't burn. I always toast mine fresh, but pre-toasted from the store is fine if you're in a rush.
No Dijon mustard? Yellow mustard thinned with water works in a pinch, but trust me on the Dijon—it's what gives this dressing that signature tang. The sugar balances the acidity perfectly, but maple syrup at half the amount is a great swap. Olive oil matters here—California avocado oil is my go-to for neutral flavor. Lemon juice? Fresh is non-negotiable—bottled tastes like sad juice. Parsley is optional but adds a pop of color. If you hate chopping, skip it and use dried oregano instead.
This salad keeps for 2 days in the fridge, but walnuts get stale after that. Store dressing separately if you're prepping ahead—it'll last 1 week. I always double the dressing because it disappears fast. For meal prep, pack the apples and celery separately to keep them crisp. The walnuts? Add them fresh before serving so they stay crunchy. Leftovers? Toss with a little extra dressing and enjoy as a quick lunch.
Why You'll Love This Recipe
- Here’s what sold me: the dressing stays fresh for days if you make it separately. Toss it in just before eating, and you’ll have leftovers that taste just as good as day one. Plus, the ingredients cost pennies—Dijon mustard and olive oil stretch forever, and apples stay crisp in the fridge for weeks.
- No Knife Skills Needed: Honestly, I chop apples and celery so rarely that my knife stays dull. This salad’s magic? Toss pre-sliced Honeycrisp apples and store-bought celery sticks straight into the bowl—no dice, no fuss. The walnuts? Just toast them in a dry pan for 3 minutes. That’s it.
- Sweet-Savory Magic: Between us, the combo of crisp Honeycrisp apples, sharp celery, and toasted walnuts with that tangy Dijon mustard is ridiculously good. The olive oil ties it all together—creamy but bright, like autumn in a bowl. (Yes, even on a Tuesday night.)
- Lunchbox Superstar: I pack this salad in mason jars for work all the time—apples and celery at the bottom, dressing on top so everything stays crisp. It’s my go-to for school lunches too, and the kids actually eat it. (My daughter picks out the walnuts first, but still asks for seconds.)
Step-by-step instructions for apple celery walnut salad
Here's how to assemble this vibrant salad with perfect texture balance every time.
Prep the Apples and Celery
Core the 2 medium Honeycrisp Apples and slice them into ⅛-inch thick pieces. Immediately place them in a large bowl and toss with 1 tablespoon of the fresh lemon juice. This prevents browning while adding bright acidity. The apples should look fresh and glistening after tossing.
Next, trim the ends from the 3 whole Celery Stalks and slice them into ¼-inch thick pieces. Add them to the bowl with the apples. The celery will add satisfying crunch that contrasts beautifully with the tender apples. Give everything another quick toss to distribute the lemon juice evenly.
Toast the Walnuts
Spread the 1 cup Walnuts on a baking sheet lined with parchment paper. Toast them in a preheated 350°F oven for 8-10 minutes, stirring once halfway through. You're looking for walnuts that smell deeply nutty and develop light golden spots on their edges.
Let them cool completely before chopping roughly with a chef's knife. The toasted walnuts will add rich, earthy flavor and satisfying bite to balance the salad's sweetness. Don't skip this step—the raw walnuts won't provide the same depth of flavor.
Whisk the Dressing
In a small bowl, whisk together the 0.5 cup Extra-Virgin Olive Oil, 2 tablespoons Apple Cider Vinegar, 1 tablespoon Granulated Sugar, 0.5 teaspoon Salt, 1 tablespoon Fresh Lemon Juice, 1 teaspoon Lemon Zest, and 0.25 teaspoon Ground Black Pepper. Start with a slow whisk to emulsify the oil and vinegar, then increase speed until the dressing is completely smooth.
Taste and adjust seasoning if needed—you might want more sweetness or acidity depending on your preference. The dressing should coat the back of a spoon with a silky, balanced flavor that's tangy, slightly sweet, and herby. This is the foundation that ties all the components together.
Combine Everything
Add the toasted walnuts to the apple and celery mixture in the large bowl. Pour the dressing over everything and toss gently but thoroughly with your hands or a large spoon. You want all the ingredients coated evenly without crushing the apples or celery.
Let the salad sit for 5 minutes before serving. This allows the flavors to meld slightly and the dressing to penetrate the ingredients. The apples should be tender but still hold their shape, the celery crisp, and the walnuts warm from their toasting.
Garnish and Serve
Just before serving, sprinkle the 0.25 cup Fresh Parsley over the top and give one final gentle toss. The parsley adds a fresh, herbaceous note that brightens the entire salad. Serve immediately while the walnuts are still warm and the dressing is most flavorful.
This salad keeps well in the refrigerator for up to 2 days, but the walnuts will lose their crispness over time. For best results, assemble just before serving. The perfect balance of sweet apples, crisp celery, nutty walnuts, and tangy dressing makes this salad a standout for any occasion.
Pro Tips For Making Apple Celery Walnut Salad
- Toss Apples Last: The acid in Dijon mustard and olive oil will make Honeycrisp apples turn dull if left too long. Dice them right before mixing—even 10 minutes early will soften the texture and dull the bright flavor. Save the best for last.
- Toast Walnuts Dry: Cold walnuts taste bland in salads. Toast them in a dry skillet over medium heat for 3-4 minutes until fragrant and golden—no oil needed. Watch closely; they burn faster than you think.
- Cut Celery Thin: Thick celery stalks get soggy fast. Slice them paper-thin (⅛-inch or less) so they hold up in the dressing. A sharp knife and steady hand make this easier—no need for a mandoline.
- Whisk Dressing Fast: Combine Dijon, olive oil, and a splash of water (or apple cider vinegar) first—it emulsifies faster than mixing everything at once. Stir vigorously for 20 seconds, then add the apples. The dressing will coat better.

Frequently asked questions
Can I substitute pears for apples in this salad?
Pears work beautifully and add a slightly different texture. Use Bosc or Anjou varieties for extra crispness. Toss the sliced pears in lemon water just like the apples to prevent browning. The natural sweetness of pears enhances the walnuts' richness perfectly.
How do I keep the apples from turning brown?
Toss freshly sliced apples with 1 tablespoon lemon juice immediately after cutting. This acidity slows oxidation. For extra protection, add 1 teaspoon sugar to the lemon juice - it creates a light syrup that preserves color. Work quickly and keep everything chilled until serving.
Can I make this salad ahead of time?
Yes, but with a few adjustments. Store the apples and celery separately in the fridge for up to 2 days. Toast walnuts fresh before serving to maintain crispness. Make the dressing separately - it keeps for 1 week. Combine everything just before eating for the best texture and flavor.
What's the best way to toast walnuts?
Spread walnuts on a baking sheet and toast in a 350°F oven for 8-10 minutes, stirring once. They're done when golden and fragrant. For a quicker method, toast in a dry skillet over medium heat for 5-7 minutes, shaking frequently. Watch closely - they burn fast!
Can I add protein to this salad?
Try adding grilled chicken strips, smoked salmon, or crumbled feta cheese. For a vegetarian option, include white beans or tofu cubes. Add protein just before serving to prevent sogginess. The salad's bright flavors complement both lean meats and plant-based options.
