Ingredients for panera bread tuna

Simple pantry staples transform into Panera's iconic tuna salad with crispy croutons.

The tuna quality makes all the difference here. Wild-caught, high-quality brands like Wild Planet or Vital Choice flake beautifully and deliver that signature texture. The cans should be packed in water, not oil—this keeps the tuna moist while still allowing it to hold its shape when flaked. For the mayo, Hellmann's or Duke's are reliable choices, but if you're feeling fancy, Kewpie mayo adds a slightly richer flavor. The celery and red onion should be fresh—no wilting or browning at the base. Trader Joe's often carries pre-diced celery if you're short on time, but fresh is always better for that crisp bite.

No Dijon mustard? Yellow mustard works fine, though you might want to add an extra half-teaspoon of lemon juice to compensate for the tang. Running out of sourdough? Ciabatta or a soft white sandwich bread will work in a pinch, though the texture won't be identical. The croutons are key—toss the bread cubes in olive oil, garlic powder, and salt before baking until golden. For extra crunch, bake them twice: once until lightly golden, then cool and bake again until crisp. The potato chips on top aren't just for looks—they add that satisfying crunch that Panera's version is famous for.

This tuna salad keeps well in an airtight container for 3-4 days in the fridge, though the croutons will lose some crunch over time. For best results, assemble the sandwich right before serving. The croutons stay crisp for up to 2 hours if stored in a sealed container, but they're best enjoyed immediately. If you're making this ahead for meal prep, store the tuna salad and croutons separately and toast the croutons fresh before assembling. The lemon juice and mustard will mellow slightly over time, so you might want to add a splash of fresh lemon juice just before serving if you've made it in advance.

Step-by-step instructions for Panera bread tuna salad recipe

Here's how to recreate that iconic crispy crouton-topped, creamy tuna salad with perfect texture every time.

Open the 2 cans of high-quality tuna and drain them thoroughly over a fine-mesh strainer. I press down gently with a rubber spatula to remove any excess liquid, which prevents a watery salad later. Transfer the drained tuna to a large mixing bowl.

Using two forks, flake the tuna into medium-sized pieces—you want chunks that hold together when mixed but break apart easily in your mouth. Avoid overworking the tuna or it'll turn into a paste. The texture should be flaky but still substantial enough to provide structure to your salad.

Add the 0.5 cup mayonnaise and 1 tablespoon yellow mustard to the flaked tuna. Using a wooden spoon, gently fold these together until fully combined. The mixture should look thick but still spreadable. This is where the magic happens—the mayonnaise provides that signature creamy texture while the mustard adds a bright tang that balances the richness.

Next, fold in the 1 tablespoon freshly squeezed lemon juice. This not only brightens the flavors but also helps prevent the mayonnaise from separating later. The lemon juice should be well incorporated, but don't overmix—you're looking for a smooth, homogenous texture without developing any gluten.

Finely dice the 2 whole celery stalks and 0.25 cup red onion. I like to use a sharp chef's knife for this step to get uniform small pieces that distribute evenly throughout the salad. Add these to the tuna mixture and gently fold them in with a spatula.

The celery provides a satisfying crunch while the red onion adds a subtle sharpness that cuts through the richness. For best results, use fresh ingredients—they'll hold their texture better than canned or frozen alternatives. Taste the mixture now and adjust seasoning with the 0.5 teaspoon salt and 0.25 teaspoon black pepper if needed.

Cut the 1 package sourdough bread into 1-inch cubes, removing any crust. In a small bowl, toss the bread cubes with 1 tablespoon extra-virgin olive oil, 0.5 teaspoon garlic powder, 0.25 teaspoon salt, and a few grinds of black pepper until evenly coated.

Spread the bread cubes in a single layer on a baking sheet and bake at 375°F for 10-12 minutes until golden brown and crispy. You want them to be toasted but not burned—watch closely as ovens vary. Remove from the oven and let cool for 5 minutes before breaking them into smaller pieces. These crispy croutons are what elevate this salad from ordinary to restaurant-quality.

Gently fold the cooled croutons into the tuna mixture, reserving about 0.25 cup for topping. The croutons should be evenly distributed but still visible throughout the salad. Transfer the salad to a serving bowl and spread it out to create a flat surface.

Crush the 1 cup potato chips into small pieces and sprinkle them evenly over the top of the salad. Add the chopped 1 tablespoon fresh dill for a pop of color and freshness. Serve immediately while the croutons are still crispy and the flavors are at their peak. This presentation mimics the iconic Panera style with that perfect crunch contrast.

Dietary considerations for this panera bread tuna

Gluten-Free Adaptations

For a gluten-free version, swap the sourdough bread for gluten-free bread like Canyon Bakehouse or Schär. These brands mimic the texture well while staying crispy. I also recommend using gluten-free croutons or making your own with gluten-free breadcrumbs and olive oil.

The tuna mixture remains the same since it's naturally gluten-free, but always check mayo labels for hidden gluten. 🌾

Dairy-Free Options

Replace the mayonnaise with dairy-free mayo like Hellmann's Vegan or Sir Kensington's. These brands replicate the creamy texture perfectly. The rest of the recipe stays the same, as the tuna salad doesn’t contain dairy.

Just ensure all toppings, like potato chips, are also dairy-free if needed. The flavor remains rich and satisfying without any dairy. 🥛

Lower-Carb Versions

Cut carbs by using low-carb bread like Mission Carb Balance or Siete. For extra crunch, make croutons with almond flour breadcrumbs instead of bread cubes.

The tuna salad itself is already low-carb, but these swaps keep the dish satisfying while reducing carbs. Serve with lettuce wraps for a lighter option. 🥗

Allergen-Friendly Tips

For nut allergies, avoid almond flour croutons and stick to traditional bread-based croutons. If you're sensitive to mustard, reduce it to ½ tablespoon or omit entirely, adding extra lemon juice for tang.

Always check labels on mayo and potato chips for potential allergens like soy or dairy. Cross-contamination is key—use separate utensils and surfaces if needed. 🚫

Vegan Substitutions

Replace the tuna with vegan "tuna" made from hearts of palm, like Gardein or Tofurky. Use vegan mayo and ensure all bread and toppings are plant-based. The texture will differ slightly, but the creamy, chunky profile remains.

For extra protein, add chickpeas to the mix. The croutons can stay the same if using vegan bread. 🌱
