Ingredients for old chicago apple walnut salad
Crisp walnuts, sweet apples, and tangy dressing create Old Chicago’s signature salad at home.
| Ingredient | Amount | Notes |
|---|---|---|
| Walnuts 🥜 | 1 ½ cups | Toasted until golden brown |
| Red Delicious Apples 🍎 | 3 medium | Thinly sliced, seeds removed |
| Red Onion 🧅 | 1 small | Thinly sliced, white part only |
| Romaine Lettuce 🥬 | 1 whole | Chopped into bite-sized pieces |
| Extra-Virgin Olive Oil 🫒 | ½ cup | For toasted walnuts and dressing |
| Dijon Mustard 🍯 | 1 tbsp | For tangy dressing base |
| Apple Cider Vinegar 🍎 | ¼ cup | For bright tang |
| Granulated Sugar 🍚 | 1 tbsp | Balances tartness |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground |
| Fresh Thyme Leaves 🌿 | 1 tbsp | Optional garnish |
The walnuts are non-negotiable for that signature crunch—Costco or Trader Joe’s have the best bulk prices. Toast them until they’re golden brown (about 5 minutes in a dry pan), then cool completely before adding to the salad. For apples, Red Delicious or Honeycrisp stay crispest when sliced—avoid Granny Smith unless you like tartness. The onion adds depth, so don’t skip it. I always buy organic red onions from the grocery store’s produce section—they’re sweeter and more flavorful than the pre-sliced bags.
No Dijon mustard? Yellow mustard at double the amount works in a pinch, but the Dijon gives that signature tang. Short on apple cider vinegar? White vinegar or lemon juice both work, though the flavor profile shifts slightly. The sugar balances the acidity—don’t skip it, even if you’re using sweet apples. For the dressing, whisk everything together until emulsified, then let it sit for 10 minutes before tossing with the salad. The flavors meld beautifully that way. If you’re prepping ahead, store the dressing separately until serving to keep the lettuce crisp.
This salad tastes even better the next day—3-4 days in the fridge, actually. Store the dressing separately in a small jar, and keep the salad components in airtight containers. The walnuts can be toasted and stored in a sealed container for up to 2 weeks if you’re meal prepping. When ready to serve, just toss everything together and drizzle with extra dressing. Garnish with fresh thyme leaves right before serving for that restaurant-quality touch.

Step-by-step instructions for Old Chicago apple walnut salad
Here’s how to assemble this perfect balance of crispy walnuts, sweet apples, and zesty dressing.
Toast the Walnuts to Perfection
Preheat your oven to 350°F. Spread the 1.5 cups walnuts evenly on a rimmed baking sheet. Toast for 8-10 minutes, stirring halfway through, until they’re golden brown and smell deeply nutty. Watch closely—they’ll darken quickly once they start browning.
Let the toasted walnuts cool completely before using them. This cooling step is important—it prevents them from releasing excess oil into your dressing later. While they cool, you’ll have time to prep the rest of the salad components without rushing.
Prepare the Crunchy Vegetable Base
Core and thinly slice the 3 medium red delicious apples, removing any seeds. Thinly slice just the white part of the 1 small red onion—this prevents the salad from becoming too sharp. Chop the 1 whole romaine lettuce into bite-sized pieces, removing any tough stems.
Place all the sliced ingredients in a large mixing bowl. Give them a gentle toss with your hands to distribute evenly. The apples should be evenly sliced for consistent texture throughout each bite. I like to work quickly here—the apples will start to brown if left exposed to air too long.
Whisk Together the Tangy Dressing
In a small bowl, combine the 0.5 cup extra-virgin olive oil, 1 tbsp Dijon mustard, 0.25 cup apple cider vinegar, 1 tbsp granulated sugar, 0.5 tsp salt, and 0.25 tsp black pepper. Whisk vigorously for 30 seconds until the sugar dissolves completely and the mixture emulsifies into a smooth dressing.
Taste and adjust—you might want to add a touch more vinegar for brightness or sugar for sweetness. The dressing should be tangy but balanced, with just enough sweetness to complement the apples. This is your chance to customize the flavor to your preference before combining everything.
Assemble and Toss the Salad
Add the cooled toasted walnuts to the vegetable mixture in the bowl. Pour the dressing over the top and toss gently but thoroughly with your hands. The walnuts should be evenly distributed throughout—this ensures each bite has that perfect crunch and flavor combination.
Let the salad sit for 5 minutes before serving. This brief resting time allows the flavors to meld together beautifully. The dressing will slightly soften the apples while maintaining their crisp texture, and the walnuts will keep their perfect toasted crunch.
Garnish and Serve Immediately
Transfer the salad to a large platter or individual serving dishes. Sprinkle with the 1 tbsp fresh thyme leaves just before serving for a fragrant finish. The thyme adds a subtle herbal note that complements all the other flavors beautifully.
Serve immediately while the walnuts are still perfectly crisp and the lettuce maintains its crunch. This salad tastes best when enjoyed fresh—each component maintains its ideal texture when served right away. Pair with grilled chicken or a crisp white wine for a complete meal.
Pro Tips For Making Old Chicago Apple Walnut Salad
- TOAST WALNUTS LOW AND SLOW: I learned this the hard way—walnuts burn faster than you think. Toss them in a dry pan over medium-low heat (not medium-high) and stir constantly for 3-4 minutes until they’re golden, not brown. High heat turns them bitter, and nobody wants that in their salad.
- SOAK RED ONION 10 MINUTES: That sharp onion bite ruins the balance. Thinly slice the red onion and toss it in ice water for 10 minutes before draining—it mellows the edge without turning mushy. (Yes, even if you’re impatient like me, this makes a real difference.)
- DICE APPLES SMALL AND ACIDIFY: Red Delicious apples oxidize fast. Cut them into ¼-inch cubes (not slices) and immediately toss with 1 teaspoon lemon juice or vinegar—this keeps them crisp and bright. Skip this, and your salad will look dull in 20 minutes.
- DRESS LETTUCE LAST: Romaine gets soggy fast. Keep the dressing (olive oil + vinegar/lemon) separate until serving—toss it right before eating. The crispness is the thing that matters most, and this guarantees it. (Your future self will thank you.)
Dietary considerations for old chicago apple walnut salad
Gluten-Free Adaptations
The classic Old Chicago Apple Walnut Salad is naturally gluten-free, but there are a few subtle adjustments to ensure complete safety. First, verify your Dijon mustard contains no hidden gluten—brands like Maille or Annie’s offer certified gluten-free options.
For the dressing, use gluten-free apple cider vinegar (like Bragg), as some vinegars may be processed in shared facilities. The walnuts, apples, and lettuce are all inherently gluten-free, but always double-check packaging for cross-contamination warnings. 🥜
Nut-Free Substitutions
For those avoiding nuts, replace the walnuts with toasted pumpkin seeds or sunflower seeds for a similar crunch. Toast them in the same way—350°F for 8-10 minutes—until golden brown. You’ll need about 1.5 cups of seeds to match the walnuts’ volume.
The seeds add a nutty flavor without the allergen risk, and they pair beautifully with the apple’s sweetness. Store-bought seeds work, but I prefer roasting my own for fresher flavor.
Dairy-Free Options
This salad is already dairy-free, but if you’re adding optional toppings like cheese, swap the traditional Gouda or cheddar for dairy-free alternatives like Miyoko’s or Violife shreds. These brands melt well and mimic the creamy texture without lactose.
For extra richness, drizzle with tahini instead of dressing—just mix 2 tbsp tahini with 1 tbsp lemon juice and 1 tsp maple syrup for a tangy, nutty alternative. 🧀
Low-Sugar Adjustments
To reduce sugar, cut the 1 tbsp granulated sugar in the dressing to ½ tbsp or use a sugar substitute like monk fruit sweetener (½ tsp). For apples, choose tart varieties like Granny Smith to balance the dressing’s acidity without added sweetness.
If you prefer a sweeter salad, add ¼ cup dried cranberries (unsweetened) for natural sweetness and a pop of color. Always taste as you go—flavor adjustments are easier before tossing!
Vegan-Friendly Swaps
This salad is vegan-friendly as written, but you can enhance it with plant-based proteins. Add ½ cup cooked quinoa or chickpeas for extra substance. For a smoky twist, toss in ¼ cup marinated artichoke hearts (drained).
Ensure your Dijon mustard is vegan (check labels—some contain honey), and use olive oil-based dressings without animal products. The salad’s natural flavors shine even without meat, making it a hearty vegan main dish. 🌱

Frequently asked questions
Can I use any type of apple for this salad?
For the best texture and flavor, stick to Red Delicious or Honeycrisp apples—they stay crisp when sliced and have a mild sweetness that pairs perfectly with the tangy dressing. Avoid Granny Smith unless you prefer a tart flavor, as their acidity can overpower the other ingredients. If you only have Granny Smith, toss them with a pinch of sugar before adding to the salad.
How long can I store the salad before serving?
The salad tastes best when served fresh, but you can prep it 1 day ahead for maximum flavor development. Store the dressing separately in a small jar and keep the salad components (apples, lettuce, walnuts) in airtight containers in the fridge. Toss everything together right before serving to maintain crispness. The walnuts will stay crunchy for up to 2 weeks if stored properly in a sealed container.
Can I make this salad without walnuts?
For a nut-free version, swap the walnuts for toasted pumpkin seeds or sunflower seeds—they provide a similar crunch and nutty flavor. Toast them at 350°F for 8-10 minutes until golden brown, just like the walnuts. You’ll need about 1.5 cups of seeds to match the walnuts’ volume. This works especially well if you’re avoiding nuts due to allergies or dietary restrictions.
Why does my dressing separate?
Dressing separation happens when the ingredients aren’t emulsified properly. To fix it, whisk the dressing vigorously for 30 seconds until smooth, then add 1 tsp Dijon mustard or a splash of cold water to help bind the mixture. If it keeps separating, store it in the fridge and give it another good whisk before using. For extra insurance, mix the dressing ingredients in a jar and shake it vigorously before pouring over the salad.
Can I add cheese to this salad?
Yes! Add ½ cup crumbled blue cheese or sharp cheddar for a richer flavor. Fold it in gently just before serving to prevent sogginess. For a lighter option, try feta cheese (drained well) or a dairy-free alternative like Miyoko’s shreds. The cheese pairs beautifully with the walnuts and apples, adding a creamy contrast to the crisp textures. Just be sure to add it last to keep everything fresh.
