Ingredients for apple walnut tuna salad
Here's what you need to make this vibrant, textured tuna salad that feels anything but basic.
| Ingredient | Amount | Notes |
|---|---|---|
| Canned Tuna in Water 🐟 | 15 oz | Drained well, flaked with fork |
| Greek Yogurt 🥛 | ½ cup | Plain, full-fat for creaminess |
| Granny Smith Apples 🍎 | 1 medium | Firm, peeled, finely diced |
| Walnuts 🥜 | ½ cup | Toasted, roughly chopped |
| Celery Stalks 🧅 | 2 whole | Finely diced, crisp |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | For light dressing |
| Dijon Mustard 🌶️ | 1 tsp | For subtle tang |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground |
| Fresh Dill 🌿 | 2 tbsp | Chopped, optional garnish |
| Crusty Bread 🍞 | 8 slices | For serving, optional |
The apples are non-negotiable for that tart crunch—Granny Smith holds up best, but Honeycrisp works too. Trader Joe's has pre-sliced apples if you're short on time, but fresh is always better. Toast the walnuts in a dry pan for 2-3 minutes until fragrant—they should smell like pure nuttiness, not burnt. For the tuna, Wild Planet or StarKist brands are my go-tos—they flake perfectly without fishy aftertaste. Celery? The fresher, the better—look for stalks that snap, not bend when broken.
No Greek yogurt? Sour cream or vegan yogurt works in a pinch, though the texture will be slightly heavier. Short on walnuts? Pecans or almonds add a different crunch, but walnuts are the star here. The lemon juice can be swapped for white wine vinegar if you prefer, but fresh lemon brightens everything. For a tangier kick, add another ½ tsp Dijon—trust me, it balances the sweetness. If you're prepping ahead, hold off on adding the apples until serving to keep them crisp.
This salad keeps beautifully for 3-4 days in the fridge, but the apples soften over time—add them fresh when serving for that perfect bite. Store the dressing (yogurt, lemon, mustard, oil) separately if prepping ahead, then mix everything together just before eating. For meal prep, portion into small containers with a slice of bread on the side—no soggy sandwiches here. The flavors actually improve after 30 minutes chilling, so make it ahead if you can.
Why You'll Love This Recipe

Step-by-step instructions for apple walnut tuna salad
Here's how to combine tart apples, crunchy walnuts, and flaky tuna into a bright, satisfying salad.
Prepare the Crunchy Base Ingredients
Toast the walnuts first—this adds depth of flavor and prevents them from turning mushy. Spread the 0.5 cup walnuts on a baking sheet and toast in a preheated 350°F oven for 8-10 minutes until fragrant and lightly golden. Watch them closely—they burn quickly! Let them cool completely before chopping roughly.
While the walnuts toast, peel and finely dice the 1 medium Granny Smith apple. I like to use a mandoline for even slices, then chop them into small cubes. Toss the diced apple with 1 tablespoon lemon juice immediately to prevent browning—this keeps them crisp and bright. Finely dice the 2 whole celery stalks and set aside. Both the apple and celery should have a clean, crisp texture when you're done.
Flake the Tuna and Mix the Dressing
Drain the 15 oz canned tuna in water thoroughly, pressing gently to remove excess moisture. Flake it with a fork into small, even pieces—this ensures even distribution in the salad. In a large mixing bowl, combine the tuna with the 0.5 cup Greek yogurt, 1 tablespoon extra-virgin olive oil, and 1 teaspoon Dijon mustard. Mix well until fully incorporated—the yogurt creates a creamy base while the mustard adds subtle tang.
Add the toasted walnuts, diced apple, celery, 0.5 teaspoon salt, and 0.25 teaspoon black pepper to the bowl. Here's the thing—don't overmix. Just gently fold everything together until combined. You want to keep those apples and celery pieces distinct for texture contrast. The salad should look vibrant with flecks of green celery, white apple, and golden walnuts throughout.
Finish and Serve
Taste the mixture and adjust seasoning if needed. I usually find the lemon juice and Dijon mustard provide enough acidity, but if it tastes flat, add a pinch more salt or a splash of lemon juice. Stir in the 2 tablespoons chopped fresh dill at the end—this adds a bright herbal note that cuts through the richness of the tuna and yogurt.
Transfer the salad to a serving bowl and chill for at least 30 minutes before serving. This lets the flavors meld together beautifully. Serve with the 8 slices crusty bread on the side for dipping. The contrast of the crispy bread with the creamy, crunchy salad makes every bite satisfying. Store leftovers in an airtight container in the refrigerator for up to 3 days, though I've never had any last that long!
Pro Tips For Making Apple Walnut Tuna Salad
- Drain and Pat the Tuna: Dump that canned tuna into a colander and give it a good press—don’t just pour it straight into the bowl. The extra water dilutes the flavor, and you’ll end up with a soggy salad instead of something that holds together. I learned this after making a batch that tasted more like tuna broth than anything else.
- Toast the Walnuts Low: Skip the high-heat blaze—walnuts burn faster than you think. Toss them in a dry pan over medium-low heat for 3-4 minutes, stirring constantly, until they’re golden and smell nutty. Overcook them, and they’ll taste bitter. (Yes, even if you’re impatient like me.)
- Grate, Don’t Dice, the Apple: A food processor does half the work here—pulse the Granny Smith until it’s a fine, pea-sized texture, not chunks. This keeps the salad creamy and prevents the apples from turning mushy after mixing with the yogurt. I used to chop them by hand, and by lunchtime, the salad looked like a fruit salad.
- Mix Celery Last: Add the celery stalks right before serving—otherwise, they’ll release water and make the whole thing watery. Cut them into thin half-moons and toss them in just as you’re dishing it up. (Pro move: Sprinkle a pinch of salt over the celery first to draw out any excess moisture.)
Regional styles of this dish
Northeast Crunch
In the Northeast, I've seen this salad elevated with local ingredients like freshly baked sourdough bread from a nearby bakery and local apples from orchards in New England. The crisp air keeps the apples extra firm, so I recommend adding them just before serving.
A dash of maple syrup—about 1 teaspoon—adds a subtle sweetness that balances the tangy lemon perfectly. This version is especially popular in New Hampshire and Vermont, where maple is a staple. 🍁
Pacific Northwest Twist
Out west, the focus shifts to fresh Dungeness crab mixed with the tuna for extra protein and a briny depth. Swap the walnuts for toasted hazelnuts—they're more common in Pacific Northwest grocery stores—and add 1 tablespoon chopped fresh chives instead of dill.
A splash of rice vinegar replaces lemon juice, giving the salad a lighter, more delicate flavor that pairs beautifully with sourdough rye bread. This version is a hit in Seattle and Portland brunch spots. 🌊
Southern Comfort
Down South, the salad gets a smoky kick with crumbled bacon (about 2 ounces) mixed into the tuna base. I also add pickled red onions—just 2 tablespoons of finely chopped ones—for a tangy crunch.
The heat is balanced with a touch of honey (about ½ teaspoon) instead of maple syrup. Serve it on buttermilk biscuits for a true Southern touch. This variation is a crowd-pleaser at Georgia and Alabama potlucks. 🍖
Midwest Heartland
The Midwest takes a simpler approach, focusing on homestyle flavors. Here, the salad often includes crispy fried onions (about ¼ cup) for extra crunch and a sprinkle of poppy seeds (about 1 teaspoon) for a nutty finish.
A splash of apple cider vinegar adds a homestyle tang, and the salad is often served with wheat dinner rolls instead of crusty bread. This version is a classic at Iowa and Ohio picnics. 🌽
West Coast Fresh
On the West Coast, the salad leans into bright, fresh flavors with avocado slices (about ½ medium avocado) added just before serving to keep them crisp. Swap the walnuts for pumpkin seeds (about ¼ cup) for a different crunch, and use lime juice instead of lemon.
This version is lighter and pairs well with whole-grain crackers or multigrain toast. It’s a staple at California and Oregon farmers' markets. 🌿

Frequently asked questions
Can I use walnut halves instead of chopped walnuts?
You can, but the texture will be different! Whole walnut halves add a satisfying bite, but they won't distribute as evenly through the salad. For best results, chop them roughly to maintain that crunchy contrast in every bite. If you prefer the halves, consider adding them as a garnish instead.
How do I keep the apples from turning brown in the salad?
Toss the diced apples with 1 tablespoon lemon juice immediately after chopping—the acid prevents browning. For extra insurance, sprinkle a pinch of salt over them, which also helps preserve their crispness. Add the apples to the salad just before serving if possible.
What's the best way to store leftovers?
Store the salad (without apples) in an airtight container for up to 3 days. Keep the apples separate and add them fresh when ready to eat to maintain their crisp texture. For longer storage, freeze the base mixture (without apples) for up to 2 months—just thaw and mix in fresh apples when serving.
Can I make this salad without Greek yogurt?
Swap the yogurt for ½ cup mayonnaise for a richer texture, or use ¼ cup sour cream for a lighter option. For a vegan version, try coconut yogurt or avocado mash—just adjust seasoning as needed. The key is maintaining that creamy base to balance the crunchy elements.
Why does my salad taste bland after sitting in the fridge?
Flavors often mellow when chilled, but a quick fix is to add a splash of lemon juice or Dijon mustard before serving. Also, try adding fresh herbs like dill or parsley—they brighten up the salad instantly. If it's still flat, a pinch of salt or a dash of hot sauce can wake up the flavors!
