Ingredients for au bon pain tuna salad
High-quality tuna, crisp veggies, and bright herbs create this iconic café-style salad.
| Ingredient | Amount | Notes |
|---|---|---|
| Flaky Tuna 🐟 | 15 oz | High-quality, in water or oil |
| Mayonnaise 🥫 | ¾ cup | High-quality, like Hellmann's or Duke's |
| Celery Stalks 🧅 | 2 whole | Fresh, crisp, organic preferred |
| English Cucumber 🥒 | 1 whole | Seedless, peeled if preferred |
| Red Onion 🧅 | ¼ cup | Finely diced, white or red |
| Fresh Dill 🌿 | ¼ cup | Chopped, stems removed |
| Fresh Parsley 🌿 | ¼ cup | Chopped, flat-leaf preferred |
| Lemon Juice 🍋 | 2 tbsp | Freshly squeezed |
| Dijon Mustard 🍯 | 1 tbsp | For depth of flavor |
| Capers 🍃 | 1 tbsp | Chopped, packed in brine |

The tuna makes or breaks this dish—high-quality flaky tuna in water or oil is non-negotiable. Wild Planet or Trader Joe's brands are my go-to for that perfect texture. Celery and cucumber should be fresh and crisp, so check the stems for bruising. English cucumbers stay crunchier than regular ones. For the herbs, fresh dill and parsley give that signature Au Bon Pain brightness—dried just won’t cut it. If you can’t find microgreens, chopped chives or extra parsley work as a garnish.
No fresh dill? Dried dill at half the amount works in a pinch, but it’s noticeably different. Running low on capers? Pickle juice or chopped cornichons add a similar briny punch. The Dijon mustard is key—skip the yellow mustard, it lacks depth. For extra richness, add 1 tbsp of sour cream or Greek yogurt. This salad keeps its crunch best when prepped 1-2 hours ahead, so plan accordingly. The lemon juice should be freshly squeezed—bottled just doesn’t have the same zing.
Store any leftovers in an airtight container with a paper towel on top to keep the veggies crisp. Good for 2-3 days in the fridge. For best texture, serve chilled. I always double the batch—half goes in sandwiches, half gets piled on greens for lunch. The flavors actually improve after chilling, so make it the night before if you can. Freezing isn’t recommended as it ruins the crunch.

Step-by-step instructions for Au Bon Pain tuna salad
This method delivers the signature chunky texture and bright flavors that make this salad legendary.
Prepare the Crunchy Vegetable Base
Cut the 2 whole celery stalks into ¼-inch dice—small enough to eat but large enough to maintain texture. Peel the 1 whole English cucumber lengthwise, then cut into ½-inch cubes. The skin stays on for extra crunch but can be removed if preferred. Finely dice the 0.25 cup red onion—small pieces distribute evenly without overpowering.
Place all chopped vegetables in a large bowl. Sprinkle with 0.5 tsp salt and 0.25 tsp black pepper, then toss gently to coat. Let them sit for 5 minutes—this draws out moisture, preventing a soggy salad later. Drain any excess liquid that collects in the bowl before proceeding.
Drain and Flake the Tuna
Open the 15 oz flaky tuna and drain it thoroughly in a fine-mesh strainer for 2-3 minutes. Press gently with a spatula to remove all liquid—this prevents a watery salad. Transfer the drained tuna to the bowl with the vegetables and break it into large, uneven flakes with your fingers. The goal is texture, not mincing.
Add the 1 tbsp Dijon mustard and 1 tbsp capers to the bowl. The capers should be chopped into small pieces—they add a briny punch that balances the richness. Stir everything together lightly, just until the tuna and vegetables are evenly distributed. Avoid overmixing, which can break down the celery and cucumber into mush.
Create the Dressing
In a separate small bowl, whisk together the 0.75 cup mayonnaise, 2 tbsp lemon juice, and 1 tsp lemon zest. The zest adds a bright, citrusy aroma that cuts through the richness of the mayonnaise. Gradually fold in the 0.25 cup fresh dill and 0.25 cup fresh parsley, reserving a few sprigs for garnish later.
This dressing should be thick but pourable—if it’s too stiff, add 1-2 teaspoons of water to loosen it. Taste and adjust seasoning with additional salt or pepper if needed. The dressing should be tangy, herby, and just slightly briny from the capers.
Combine and Chill
Pour the dressing over the tuna and vegetable mixture, then fold gently with a large spoon or rubber spatula. Work quickly but deliberately to avoid crushing the celery and cucumber. Taste a spoonful—it should be bright, herby, and slightly tangy with a crisp texture. If it needs more acidity, add another ½ teaspoon of lemon juice. If it’s too dry, stir in 1 teaspoon of water to bind everything together.
Transfer the salad to an airtight container and refrigerate for at least 1 hour—this allows the flavors to meld and the celery to soften slightly without losing its crunch. The longer it chills, the better the flavors develop, but it’s best enjoyed within 24 hours for optimal texture.
Serve with Garnish
Before serving, sprinkle the salad with the reserved 0.25 cup microgreens and a final pinch of lemon zest for a pop of color and freshness. Serve immediately on a bed of mixed greens or with crusty bread for dipping. The contrast of crisp vegetables, flaky tuna, and creamy dressing makes this salad irresistibly satisfying.
For extra crunch, serve with a side of sliced radishes or pickled onions. The acidity of the pickles complements the richness of the tuna salad perfectly, balancing every bite.
Pro Tips For Making Au Bon Pain Tuna Salad
- Drain Tuna Thoroughly: I learned this the hard way—skipping this step turns your salad into a soggy mess. After opening the can, press the tuna through a fine-mesh sieve or paper towels to remove all the liquid. The flakes will stay crisp, and your texture stays perfect.
- Dice Onion Fine: Red onion adds bite, but big chunks make every bite a mouthful of sharpness. Use a sharp knife and cut into tiny, even pieces—think rice grain size. This way, the flavor blends smoothly without overpowering.
- Mix Celery Last: Celery releases moisture, which can turn mayo-based salad into a gloopy disaster. Add it just before serving so it stays crisp. If you must prep ahead, keep it separate until the last second.
- Use Cold Mayo: Room-temperature mayo makes the salad taste flat and heavy. Scoop it straight from the fridge and mix it in last—cold mayo keeps the tuna crisp and balances the flavors. No need to chill the whole bowl; just fold it together right before eating.

Frequently asked questions
Why does this recipe use English cucumbers instead of regular cucumbers?
English cucumbers have thinner, more tender skin and fewer seeds, making them crispier and milder than regular cucumbers. They stay firm when diced, adding that signature Au Bon Pain crunch without bitterness. Plus, their shape makes them easier to peel and cube evenly.
Can I make this tuna salad ahead of time for a lunch gathering?
This salad actually tastes better after chilling for 1-2 hours—the flavors meld and the celery softens slightly without losing crunch. For parties, prepare it the night before and store in an airtight container with a paper towel on top to absorb moisture. Serve chilled for optimal texture.
What's the best way to keep the celery from getting soggy?
Salt the celery and cucumber first, then let them sit for 5 minutes to draw out excess moisture. After draining, pat them dry with a paper towel before mixing with the tuna. Also, avoid overmixing once combined—gentle folds preserve the texture. If prepping ahead, store in a container with a paper towel layer on top.
Can I substitute Greek yogurt for mayonnaise to make it lighter?
Yes! Replace half the mayo with plain Greek yogurt for a lighter texture while keeping creaminess. Add 1 extra tbsp lemon juice to balance the tang. For extra richness, stir in 1 tsp Dijon mustard to compensate for the yogurt's milder flavor. The result will be just as satisfying but with fewer calories.
How do I serve this tuna salad like Au Bon Pain does?
Pile it high on toasted sourdough or rye bread for a classic sandwich, or serve it on a bed of mixed greens with sliced radishes. For presentation, garnish with microgreens and a sprinkle of lemon zest. Serve with crisp white wine or iced tea to complete the café experience. The key is generous portions—Au Bon Pain's version is always piled high!
