Ingredients for apple walnut tuna salad

Crunchy walnuts, sweet apples, and flaky tuna—this salad packs protein and texture in every bite.

Ingredient Amount Notes
Flaked Tuna in Water 🐟 15 oz High-quality, drained well
Honeycrisp Apples 🍎 1 ½ cups Diced small, skin on
Walnuts 🥜 1 cup Toasted lightly, chopped
Plain Greek Yogurt 🥛 ¾ cup Full-fat for creaminess
Lemon Juice 🍋 2 tbsp Freshly squeezed
Honey 🍯 1 ½ tbsp Wildflower preferred
Extra-Virgin Olive Oil 🫒 1 tbsp For richness
Celery 🧅 ½ cup Diced fine, optional
Fresh Dill 🌿 2 tbsp Chopped, stems removed
Diamond Crystal Kosher Salt 🧂 ½ tsp Adjust to taste
Freshly Ground Black Pepper 🌶️ ¼ tsp For finishing
Crusty Bread 🍞 8 slices For serving, optional

The walnuts are non-negotiable here—they bring that satisfying crunch. Trader Joe's has the best pre-toasted ones, but if you toast your own, 5 minutes at 350°F makes all the difference. Honeycrisp apples are ideal for their crisp texture, but Fuji or Gala work too—just dice them small so they don’t get mushy. The tuna? Wild-caught brands like Wild Planet or Vital Choice have the best texture, but any high-quality canned tuna in water will do. For extra freshness, drain it really well and pat it dry with paper towels.

No honey? Maple syrup at half the amount works in a pinch, though it’ll be slightly less floral. Swapping walnuts? Pecans or candied pecans add a similar crunch, but walnuts are the star here. Short on dill? Fresh parsley or chives give a milder flavor. The Greek yogurt makes this creamy without mayo—full-fat is key for that rich texture. If you’re avoiding honey entirely, a splash of apple cider vinegar adds tang to balance the sweetness.

This salad keeps beautifully for 3-4 days in the fridge, sealed in an airtight container. The apples stay crispest if you toss them with a pinch of salt and lemon juice before adding to the mix. For meal prep, store the dressing separately and mix everything just before serving. The walnuts can be toasted ahead and stored in the freezer for up to 3 months—just toast again before using. Serve on toasted sourdough for a hearty sandwich or with lettuce cups for an elegant appetizer.

Step-by-step instructions for apple walnut tuna salad

This protein-packed salad combines sweet apples, crunchy walnuts, and flaky tuna for a refreshing bite.

1

Prepare the Apples and Celery

Start by dicing the 1.5 cups Honeycrisp Apples into small, even pieces—about ¼-inch cubes. The skin-on texture adds subtle sweetness and visual appeal. Place them in a medium bowl and immediately toss with 1 tbsp Lemon Juice to prevent browning. This acidity also brightens the natural apple flavor.

Next, dice the 0.5 cup Celery into fine pieces—you want them almost confetti-like. Add them to the bowl with the apples and toss gently to combine. The celery provides a crisp contrast that balances the richness of the tuna and walnuts. If you prefer a more pronounced celery flavor, you can lightly pulse it in a food processor before dicing.

2

Toast and Chop the Walnuts

Spread the 1 cup Walnuts in a single layer on a baking sheet and toast them in a 350°F oven for 5-7 minutes until they release their nutty aroma and turn a few shades lighter. Watch closely—they toast quickly and can burn easily. Let them cool for 2 minutes before transferring to a cutting board.

Chop the toasted walnuts coarsely—you want chunks that add texture without overwhelming the salad. Set them aside for now. The toasted flavor enhances the walnuts' natural richness, making them the perfect crunchy counterpoint to the creamy tuna mixture.

3

Mix the Creamy Base

In a separate bowl, combine the 0.75 cup Plain Greek Yogurt, 1.5 tbsp Honey, and 1 tbsp Extra-Virgin Olive Oil. Whisk until smooth and fully incorporated. The Greek yogurt provides a tangy, creamy foundation that binds the salad together. The honey adds subtle sweetness, while the olive oil contributes richness and helps emulsify the mixture.

Add the 15 oz Flaked Tuna in Water (drained thoroughly) to the yogurt mixture and gently fold it in with a fork. Be careful not to overmix—just combine until the tuna is evenly distributed. The flakes should remain intact for texture. Season with 0.5 tsp Diamond Crystal Kosher Salt and 0.25 tsp Freshly Ground Black Pepper to taste. This step creates the creamy base that ties all the ingredients together.

4

Combine All Ingredients

Add the prepared apple and celery mixture to the tuna-yogurt base and gently fold everything together. The apples should soften slightly from the lemon juice, but they should still hold their shape. Sprinkle in the 2 tbsp Fresh Dill and the toasted walnuts, then fold them in just until distributed—you want the walnuts to remain visible for texture.

Taste the salad and adjust the seasoning if needed. You might want to add a pinch more salt or a drizzle of honey if the apples need balancing. The final mixture should be creamy yet bright, with a perfect balance of sweet, savory, and crunchy elements. Let it sit for 5 minutes before serving to allow the flavors to meld.

5

Serve with Crusty Bread

Divide the salad evenly among 4 serving bowls or plates. Garnish with an extra sprinkle of fresh dill and a few more toasted walnuts for visual appeal. Serve immediately with 8 slices Crusty Bread on the side for scooping. The bread adds a satisfying crunch and helps soak up any extra dressing.

This salad keeps well in an airtight container in the refrigerator for up to 2 days, though the apples may soften slightly over time. For best texture, serve within a few hours of preparation. The combination of sweet apples, nutty walnuts, and protein-rich tuna makes this a satisfying meal any time of day.

Pro Tips For Making Apple Walnut Tuna Salad

  • Drain and Pat Tuna Dry: That water in canned tuna makes the salad soggy—trust me, I’ve drowned salads before. Drain it well, then grab a clean kitchen towel and press out every last drop. The texture stays crisp, not mushy, and the flavors shine through.
  • Toast Walnuts Low and Slow: I used to burn them in a screaming-hot pan, then wonder why they tasted bitter. Instead, toast them in a dry skillet over medium-low heat for 5-6 minutes, stirring constantly, until they’re fragrant and just golden. Remove them before they darken—you want nutty, not smoky.
  • Use Cold Yogurt Straight: Warm Greek yogurt thins out and turns the salad into a sad, watery mess. Scoop it straight from the fridge, let it sit out for 10 minutes max, and mix it in last. Cold yogurt keeps the apples from breaking down and adds that perfect tangy creaminess.
  • Slice Apples Last, Toss Fast: Honeycrisp apples oxidize fast—even if you squeeze lemon juice on them, they’ll still turn brown and mushy if you prep them too early. Slice them right before mixing, then toss the whole salad together immediately. The lemon juice and yogurt will cling better, and the texture stays bright.

Best sauces and condiments for this dish

Creamy Yogurt Dressing

The Greek yogurt base is the secret weapon here—it keeps the salad light yet rich without the heaviness of mayo. I like using full-fat Greek yogurt (like Fage 5%) for that velvety texture, but if you prefer a lighter option, 2% works too.

For extra tang, add 1 tsp Dijon mustard to the yogurt mixture before combining with other ingredients. This adds depth that balances the sweetness of the apples beautifully. 🥛

Lemon-Honey Glaze

The honey-lemon dressing is what elevates this salad from ordinary to extraordinary. I recommend using wildflower honey for its floral notes, but clover honey is a great budget-friendly alternative. For a tangier twist, increase the lemon juice to 3 tbsp and reduce honey to 1 tbsp.

This dressing not only ties the flavors together but also prevents the apples from browning too quickly. 🍋

Spicy Mustard Twist

If you love a little heat, swap the honey for 1 tbsp whole-grain mustard mixed with 1 tsp apple cider vinegar. This creates a tangy, slightly spicy dressing that pairs perfectly with the sweet apples and nutty walnuts.

For extra kick, add a pinch of cayenne pepper or a dash of hot honey (like Chimayó brand). It’s a game-changer for those who enjoy bold flavors. 🌶️

Herb-Infused Olive Oil

For a brighter, fresher take, infuse your olive oil with herbs before adding it to the salad. Heat 1 tbsp extra-virgin olive oil with 1 tsp fresh dill and 1 tsp fresh parsley in a small saucepan for 1 minute, then let it cool.

Stir this into the yogurt base for an aromatic boost. The herbs add a subtle earthiness that complements the tuna and apples wonderfully. 🌿

Sweet and Tangy Vinaigrette

For a lighter option, replace the yogurt with a simple vinaigrette. Whisk together 2 tbsp olive oil, 1 tbsp apple cider vinegar, 1 tsp honey, and ½ tsp Dijon mustard.

This dressing keeps the salad fresh and bright, with a perfect balance of sweet and tangy notes. It’s ideal if you’re watching your fat intake or prefer a lighter texture. 🍯

Frequently asked questions

1

Can I use canned tuna in oil instead of water?

You can, but it will make the salad richer and slightly oilier. Drain the tuna thoroughly and pat it dry with paper towels to remove excess oil. For every 5 oz of tuna in oil, reduce the Greek yogurt by 1 tbsp to balance the extra fat. The flavor will be more robust, but the texture may be slightly heavier.

2

How do I keep the apples from turning brown?

Toss the diced apples with 1 tbsp lemon juice immediately after cutting—this prevents browning by breaking down enzymes that cause oxidation. For extra insurance, store the prepped apples in an airtight container with a damp paper towel until ready to use. The lemon juice also enhances their natural sweetness.

3

Can I make this salad ahead of time?

Yes, but store the dressing and tuna separately from the apples and walnuts. Combine everything just before serving to maintain crispness. The apples will soften slightly over time, but the salad still tastes delicious. If prepping ahead, keep the walnuts toasted separately and add them fresh for maximum crunch.

4

What’s the best way to serve this salad?

This salad shines as a sandwich filling with crusty bread, a protein-packed appetizer in lettuce cups, or a side dish with grilled fish. For extra flair, serve it in a hollowed-out apple or on a bed of mixed greens. The creamy texture makes it perfect for scooping—great for picnics or office lunches!

5

Can I substitute walnuts with another nut?

Try pecans for a sweeter crunch or almonds for a milder flavor. Toast them first (same method) and chop coarsely. For a nut-free version, use toasted pumpkin seeds or crushed potato chips for a salty crunch. Just adjust the quantity to taste.
