Ingredients for gelson's tuna salad
Bright, zesty layers with premium tuna and fresh herbs transform this classic into a café-worthy masterpiece.
| Ingredient | Amount | Notes |
|---|---|---|
| Gelson's Premium Canned Tuna in Water 🐟 | 1 can | High-quality, flaky variety preferred |
| Mayonnaise 🥛 | ½ cup | Dijon-infused for depth of flavor |
| Fresh Lemon Juice 🍋 | 2 tbsp | Freshly squeezed for tangy brightness |
| Celery Stalks 🧅 | 2 whole | Finely diced, crisp texture essential |
| Red Onion 🧅 | 2 tbsp | Finely minced, for subtle bite |
| Dijon Mustard 🍯 | 1 tbsp | For authentic depth and tang |
| Fresh Dill 🌿 | 2 tbsp | Chopped, for herbaceous brightness |
| Fresh Chives 🌿 | 1 tbsp | Finely chopped, for fresh aroma |
| Capers 🍅 | 1 tbsp | Chopped, for briny contrast |
| Kosher Salt 🧂 | ½ tsp | Diamond Crystal preferred |
| Freshly Ground Black Pepper 🌶️ | ¼ tsp | For subtle heat balance |
| Extra-Virgin Olive Oil 🫒 | 1 tsp | For finishing drizzle |
The foundation begins with Gelson's premium canned tuna in water—its rich, flaky texture is non-negotiable. Store-brand tuna can work in a pinch, but you'll notice the difference in mouthfeel. For the celery, organic stalks from the produce section yield the crispest texture, and avoid pre-diced varieties that lose their crunch. Fresh dill and chives should be bright green with no wilting—these herbs make the difference between a basic salad and a vibrant, restaurant-quality dish. Penzeys or local specialty markets often carry premium dried dill if fresh isn't available, but fresh is ideal. The red onion should be vibrant purple—yellowing indicates age and dulls the flavor profile.
No Dijon mustard? Substitute with 1 tsp of regular mustard plus 1/4 tsp of lemon zest for a similar tang. Capers unavailable? A pinch of salted cornichons or 1/2 tsp of caper juice from a jar works in a bind. For a lower-fat version, replace half the mayo with Greek yogurt—the texture remains creamy while reducing richness. If your celery tastes bitter, soak the diced pieces in ice water for 10 minutes before draining to restore crispness. The lemon juice should be freshly squeezed—bottled juice lacks the bright acidity needed to cut through the tuna's richness.
This salad maintains its peak freshness for 3-4 days when stored in an airtight container in the refrigerator. Portion into small containers for easy grab-and-go lunches—each serving stays vibrant and crunchy. For meal prep, add the celery and onion last to preserve their texture. If making ahead, omit the fresh herbs until serving to prevent wilting. The flavors actually improve after sitting for 1-2 hours, allowing the ingredients to meld. For a picnic-friendly version, pack the dressing separately and mix just before serving to maintain crispness.

Step-by-step instructions for Gelson's market tuna salad
This method delivers a perfectly balanced tuna salad with vibrant flavors and ideal texture.
Prepare the Celery and Onion Base
Using a sharp chef's knife, trim the ends from the 2 whole celery stalks and cut them into a fine dice—about ⅛-inch pieces. The celery should be uniformly small to distribute evenly throughout the salad without overwhelming the texture. Place the diced celery in a medium mixing bowl.
Next, finely mince the 2 tablespoons of red onion. For best results, cut off the root end and slice the onion in half lengthwise, then slice thinly before making your final mince. The onion should be so finely chopped it's nearly indistinguishable when mixed—this prevents any harsh bite from interfering with the smooth mayonnaise base.
Combine Wet Ingredients for Emulsion
In the same mixing bowl with the celery and onion, add the 0.5 cup mayonnaise, 2 tablespoons fresh lemon juice, and 1 tablespoon Dijon mustard. Using a silicone spatula, gently fold these ingredients together until fully incorporated. The mayonnaise should begin to lighten in color slightly as the lemon juice and mustard integrate.
This initial combination creates the foundational emulsion that will bind the salad. Be careful not to overmix at this stage—just enough to blend the ingredients without developing gluten or creating air pockets that could make the final texture uneven.
Incorporate the Tuna and Seasonings
Open the 1 can of Gelson's Premium Canned Tuna in Water and drain it thoroughly, pressing gently on the fish to remove excess liquid. Add the tuna directly to the mixing bowl and use your spatula to break up any large chunks into smaller, more uniform pieces. This ensures each bite has consistent texture.
Next, add the 0.5 teaspoon kosher salt and 0.25 teaspoon freshly ground black pepper. Sprinkle the chopped 2 tablespoons fresh dill and 1 tablespoon fresh chives over the mixture. Gently fold everything together until the herbs are evenly distributed throughout the salad. The tuna should now be fully coated in the mayonnaise emulsion, creating a cohesive texture.
Add Briny Contrast and Final Adjustments
Chop the 1 tablespoon capers into small pieces using kitchen shears for efficiency. Add them to the bowl along with the 1 teaspoon extra-virgin olive oil. The capers will provide a briny contrast that brightens the entire salad. Taste the mixture at this point and make any final adjustments—additional lemon juice if needed for brightness, or more salt if the flavors feel muted.
Once satisfied with the balance, give the salad one final gentle fold to ensure all components are uniformly distributed. The finished tuna salad should have a vibrant color from the herbs and capers, with a smooth yet textured consistency from the celery and onion.
Pro Tips For Making Gelson'S Tuna Salad
- Drain and Pat Dry: Gelson’s tuna in water holds onto its own juices like a stubborn kid at a pool. Drain it well, then press the tuna chunks between paper towels—this keeps your salad from turning into a sad, watery mess. I learned this the hard way after making a batch that looked more like tuna soup.
- Slice Onion Thin: Red onion should be paper-thin, not chunky. Use a mandoline or a sharp knife and slice against the grain—this prevents bite-sized onion bombs. My grandmother swore by this, and she was right: the flavor distributes evenly, not in clumps.
- Mix Lemon Last: Add the lemon juice after everything else is combined. If you toss it in early, the acid will break down the mayo and turn your salad into a greasy, curdled disaster. Wait until the end—trust me, your taste buds will notice.
- Chill Before Serving: Let the salad sit in the fridge for at least 30 minutes before eating. The flavors meld better when cold, and the celery softens just enough to be tender, not crunchy. I skip this when I’m lazy, but the dish is noticeably better when I don’t.
Health benefits of these flavors
Protein Powerhouse
This tuna salad delivers a high-quality protein punch with 25 grams of protein per serving—thanks to the Gelson’s premium canned tuna used in the recipe. Tuna is one of the most nutrient-dense fish available, packed with selenium (a powerful antioxidant) and vitamin B12 (essential for energy and nerve function).
The lean protein in tuna also makes this salad ideal for weight management or low-fat diets, as it keeps you full without the heavy feeling of creamier salads. 💪
Heart-Healthy Fats
The extra-virgin olive oil and Dijon mustard in this recipe contribute heart-healthy monounsaturated fats, which help lower LDL cholesterol when replacing saturated fats. The omega-3 fatty acids from tuna (especially if using wild-caught varieties) further support cardiovascular health by reducing inflammation.
Unlike traditional tuna salads made with heavy mayo, this version balances richness with bright, fresh ingredients that keep it light yet satisfying.
Digestive Support
The fresh celery and red onion in this salad provide prebiotic fiber, which feeds beneficial gut bacteria and supports digestive health. Celery is particularly high in insoluble fiber, promoting regularity, while the capers add a probiotic-friendly tang.
The lemon juice also aids digestion by stimulating stomach acid production, making this salad easier to digest than heavier, oil-based versions. For extra fiber, consider adding diced cucumber or avocado to your serving.
Vitamin Boost
This tuna salad is a vitamin powerhouse, thanks to the fresh herbs (dill and chives) and lemon juice. The vitamin K in celery supports bone health, while the vitamin C from lemon juice enhances iron absorption from the tuna.
The folate in dill aids in cell repair, and the flavonoids in red onion provide anti-inflammatory benefits. Even a single serving delivers 20% of your daily vitamin C needs, making it a nutrient-dense lunch option. 🌿
Low-Calorie, High-Nutrient
At just around 200 calories per serving, this tuna salad is a smart choice for those watching their calorie intake. The high protein and fiber content helps stabilize blood sugar, preventing energy crashes.
The absence of heavy cream or butter keeps it light yet filling, making it perfect for meal prep lunches or post-workout recovery. For an even lower-calorie option, swap half the mayo for nonfat Greek yogurt without sacrificing creaminess.
Antioxidant-Rich
The capers, lemon juice, and fresh herbs in this salad are antioxidant superstars, helping combat oxidative stress and cell damage. Capers are particularly rich in polyphenols, which have been linked to reduced risk of chronic diseases.
The astaxanthin in wild-caught tuna (if used) adds an extra layer of anti-inflammatory protection. This makes the salad not just delicious, but also a functional food that supports long-term health. ✨

Frequently asked questions
Can I use Gelson's tuna in oil instead of water?
Yes, but you'll need to adjust the oil content. Drain the tuna thoroughly and use 1 teaspoon less olive oil in the recipe to maintain balance. The tuna in oil version adds richness, so you may also want to reduce mayo slightly (¼ cup instead of ½ cup) to prevent heaviness.
How do I keep the celery from getting soggy?
Add the celery and red onion last, right before serving. If prepping ahead, store them separately in an airtight container with a paper towel to absorb moisture. For extra crunch, soak diced celery in ice water for 10 minutes before draining and adding to the salad.
What's the best way to serve this tuna salad?
This versatile salad works perfectly in whole-grain bread for classic sandwiches, as a topping for crackers or crostini, or alongside fresh greens for a light salad. For a gourmet touch, spoon it over avocado slices or toasted baguette rounds. It also makes a great appetizer with endive leaves or cucumber slices for scooping.
Can I make this tuna salad ahead of time?
This salad actually tastes better after 1-2 hours as flavors meld. Store in an airtight container for up to 3-4 days. Keep the fresh herbs separate until serving to maintain their vibrancy. For meal prep, portion into small containers for easy grab-and-go lunches.
What if I don't have Dijon mustard?
Mix 1 teaspoon regular mustard with ¼ teaspoon lemon zest for a similar tang. Alternatively, use 1 teaspoon yellow mustard and add an extra ½ teaspoon lemon juice to compensate. The Dijon adds depth, but these substitutes work in a pinch.
