Salads
This chunk light tuna salad recipe transforms simple pantry staples into a restaurant-worthy dish with crisp celery crowns and a perfectly balanced, zero-mayo creaminess. The secret lies in using finely diced celery and red onion for texture, while Greek yogurt replaces mayo for a lighter yet rich foundation.
I developed this recipe after realizing most tuna salads either taste too heavy or lack freshness—this version fixes both problems with just 10 minutes of prep.
The magic happens in the seasoning blend: lemon juice brightens the tuna, Dijon mustard adds depth, and fresh dill brings that signature seafood salad freshness. What makes this different is the yogurt base—it provides creaminess without the heaviness of mayo, while still delivering that classic tuna salad satisfaction.
The celery gets finely chopped and tossed in just before serving to maintain its crisp texture.
By the time you assemble this salad, you'll have a dish that's light enough for a lunch salad but substantial enough to serve as a main course. The tuna stays tender and flavorful, the celery maintains its satisfying crunch, and the yogurt dressing creates just the right amount of creaminess.
It's the kind of recipe that proves healthy eating can still be indulgent.
Perfect for meal prep, potlucks, or a quick lunch that feels special. This version scales beautifully—double the batch and store in the fridge for up to 3 days.
The flavors actually improve as the celery softens slightly and absorbs more of the dressing, making it even more delicious when reheated gently.
Ingredients for chunk light tuna salad
Pantry staples meet fresh flavors for this light, creamy tuna salad without mayo.
| Ingredient | Amount | Notes |
|---|---|---|
| Chunk Light Tuna in Water 🐟 | 15 oz | High-quality, drained well |
| Plain Greek Yogurt 🥛 | ¾ cup | Full-fat for creaminess |
| Fresh Dill 🌿 | ¼ cup | Chopped, stems removed |
| Red Onion 🧅 | ¼ cup | Finely diced, crisp |
| Celery 🧅 | 2 cups | Finely chopped, crisp |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | For extra richness |
| Lemon Juice 🍋 | 1 ½ tbsp | Freshly squeezed |
| Dijon Mustard 🌶️ | 1 tsp | For depth of flavor |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Ground Black Pepper 🌶️ | ¼ tsp | Freshly ground preferred |
| Capers 🍈 | 1 tsp | Chopped, optional |
| Fresh Lemon Zest 🍋 | 1 tsp | For brightness |
The tuna is the star here—high-quality chunk light makes all the difference. Trader Joe's or Wild Planet brands are my go-tos for that perfect texture. If you're using canned tuna, drain it really well—no one likes soggy salad. The Greek yogurt should be full-fat for that classic mayo creaminess without the guilt. Fage or Siggi's are my favorites, but any plain Greek yogurt works. Fresh dill is non-negotiable for that signature seafood flavor—dried just won't cut it here.
No Greek yogurt? Vegan mayo or sour cream works in a pinch, but the texture will be slightly different. Short on dill? Fresh parsley at half the amount gives a milder flavor. The capers are optional but add that briny punch—Trader Joe's has them pre-chopped for convenience. For extra richness, swap half the yogurt for avocado (mashed). The celery and onion need to be finely chopped and crisp—use a sharp knife or food processor for even bits. Taste as you go—this salad needs just a touch of sweetness, so the lemon zest is key.
This salad keeps beautifully for 3 days in the fridge—flavors actually meld better overnight. Store the dressing separately if you want to keep the celery extra crisp. For meal prep, portion into containers with a little extra dressing at the bottom so everything stays moist. The tuna stays fresh longest if you add the celery and onion just before serving—trust me on this. Freezes for 1 month if you're prepping ahead, but the texture changes slightly after thawing.

Step-by-step instructions for chunk light tuna salad
Here's how to make a bright, creamy tuna salad without mayo—crisp celery and tangy lemon shine through.
Drain and Flake the Tuna
Open the 15 oz can of chunk light tuna and drain it thoroughly in a fine-mesh strainer, pressing gently on the chunks to remove all water. Transfer the drained tuna to a large mixing bowl—you want it completely dry to prevent a watery salad. I like to use my fingers to break up any large chunks into smaller, bite-sized pieces while keeping the texture intact.
This step is crucial because any remaining water will dilute your dressing later. If you notice any liquid pooling in the bowl, drain it again. The tuna should look dry and slightly oily, not wet. This ensures your salad stays creamy and holds together beautifully.
Chop the Celery and Onion
Use a sharp chef's knife to finely chop the 2 cups of celery into small dice—about 1/8-inch pieces. The goal is to keep the celery crisp, so don't over-chop it into a paste. Transfer the chopped celery to the bowl with the tuna. Next, finely dice the 0.25 cup red onion into tiny pieces—you want them so small they'll practically disappear in the final salad.
Here's the thing—crisp celery and finely diced onion are what give this tuna salad that classic, satisfying crunch. If you're worried about the onion being too strong, don't worry; the lemon and dill will balance it out perfectly. I like to use a food processor for the onion to ensure uniform tiny pieces, but a sharp knife works just as well if you take your time.
Mix the Dressing Ingredients
In a small bowl, whisk together the 0.75 cup plain Greek yogurt, 1 tbsp extra-virgin olive oil, 1.5 tbsp lemon juice, 1 tsp Dijon mustard, 0.5 tsp salt, and 0.25 tsp ground black pepper until completely smooth. The mixture should be thick and creamy—this is your base. Then, stir in the 0.25 cup chopped fresh dill, 1 tsp chopped capers, and 1 tsp fresh lemon zest.
This is where the magic happens—the yogurt replaces mayo while keeping the salad rich and creamy. The lemon juice and zest add that bright, fresh flavor that cuts through the richness. I always taste the dressing before adding it to the tuna to make sure it's balanced—you want it tangy but not sour, and well-seasoned but not overpowering. If it needs more salt, add a pinch now.
Combine Everything
Pour the dressing mixture over the tuna, celery, and onion in the large bowl. Using a wooden spoon or spatula, gently fold everything together until fully combined and evenly coated. Be careful not to overmix—just combine until the ingredients are distributed evenly. The salad should look creamy with visible chunks of tuna, celery, and onion.
This is the moment that matters: let the salad sit for 5 minutes before serving. This gives the flavors time to meld together and the celery a chance to soften just slightly—still crisp, but not crunchy. If you're serving it on sandwiches or crackers, this resting time ensures everything holds together beautifully. Taste again before serving and adjust seasoning if needed—sometimes the flavors need a little more lemon or salt after everything's mixed.
Pro Tips For Making Chunk Light Tuna Salad
- Drain and Pat Dry: Chunk light tuna in water has way more liquid than you’d expect—skip draining it straight from the can, and your salad will turn into a watery mess. Instead, pour the tuna into a fine-mesh strainer, let it drain for 30 seconds, then press the chunks gently with a paper towel to soak up extra moisture. (Yes, it’s tedious, but trust me, the texture makes a real difference.)
- Mix Yogurt Last: Adding Greek yogurt too early makes the tuna release more water, turning your salad into a sad, soupy thing. Hold off until the very end, and fold it in just enough to coat the tuna—about 2 tablespoons per 5-ounce can. If you’re worried about it separating, stir in a splash of lemon juice first to stabilize it.
- Soak the Onion: Red onion is sharp and bitter raw, and no amount of chopping will fix that. Toss the thinly sliced pieces in ice water for 10 minutes before adding them to the salad—it mellows the flavor and keeps them crisp. (Pro move: Drain them well or they’ll dilute the whole thing.)
- Pulse the Celery: Instead of chopping celery into tiny pieces (which turn to mush), pulse it in a food processor with a splash of water until it’s finely minced but still holds its shape. This keeps it from turning into a watery sludge while adding just the right texture. (No food processor? Use a knife, but chop it small—think rice-sized bits, not matchsticks.)
Make-ahead tips for this chunk light tuna salad
Fridge Prep Timeline
Make this tuna salad 24 hours ahead for the best flavor development. The Greek yogurt dressing thickens slightly in the fridge, while the lemon and dill flavors deepen.
I always prep mine the night before—just store it in an airtight container with parchment paper pressed against the celery to maintain crispness. The tuna stays fresh longest when kept separate until serving. 💪
Freezer-Friendly Packaging
For longer storage, portion the dressing and tuna separately in freezer-safe containers. Freeze the dressing for up to 1 month—it thaws in 15 minutes in the microwave. When ready to serve, combine with freshly chopped celery and onion.
The texture changes slightly after freezing, but the flavor remains bright and tangy. I use Glasslock containers for easy reheating.
Meal Prep Containers
Divide into 4-6 portions in glass containers with tight-sealing lids. Store the dressing at the bottom first, then add the tuna mixture on top. This keeps everything moist and prevents the celery from getting soggy.
I like using Pyrex wide-mouth containers because they're microwave-safe and stackable. Label with dates—this salad stays fresh for 3 days in the fridge.
Reheating Secrets
For a quick lunch, microwave individual portions on medium power for 1-2 minutes, stirring halfway. Add 1 tsp water to prevent drying out. The yogurt base reheats beautifully, but the celery will soften more—keep this in mind if you prefer extra crunch.
For sandwiches, assemble fresh to maintain texture. The flavors actually improve after reheating slightly! 🔥
Portion Control Tips
Use ½ cup portions for single servings or 1 cup portions for larger meals. Store extra dressing separately in a small container—this lets you adjust creaminess when serving. I keep a small jar of dressing in my fridge for quick tuna salad sandwiches.
The yogurt base also works great for dipping crackers or veggies when mixed with a splash of water.
Day-of Assembly
Just before serving, add freshly chopped celery and onion to maintain crispness. The yogurt dressing absorbs flavors better when combined fresh. I like to garnish with extra lemon zest and dill right before eating.
This keeps the salad looking vibrant and tasting fresh. The 5-minute rest before serving ensures perfect texture and flavor balance. 💫

Frequently asked questions
Can I use regular tuna instead of chunk light tuna?
While you can use regular tuna, chunk light tuna is ideal for this recipe because its flaky texture holds up better when mixed with the yogurt dressing. Regular tuna tends to break down more, potentially making your salad too soft. If you must use it, look for "chunk" style tuna rather than flaked varieties to maintain texture.
Why does my tuna salad get watery?
Watery tuna salad usually means the tuna wasn't drained properly or the celery released too much moisture. Always drain the tuna thoroughly in a strainer and press gently to remove excess water. For extra insurance, pat the drained tuna with a paper towel before mixing. Also, chop celery just before adding it to keep it crisp rather than prepping it hours ahead.
What's the best way to keep celery crisp in this salad?
Add celery just before serving to maintain maximum crunch. If prepping ahead, store it separately in an airtight container with a paper towel to absorb moisture. Another trick is to toss chopped celery in cold water for 10 minutes before draining and adding to the salad—this helps preserve its crispness. For meal prep, add celery only when ready to eat.
Can I make this salad without Greek yogurt?
Yes! For a dairy-free version, use vegan mayo or blend silken tofu with lemon juice and olive oil until smooth. For a lighter option, mix mashed avocado with a little Greek yogurt (if tolerating dairy). The key is maintaining creaminess—just ensure your substitute has enough fat content to bind the ingredients properly. The flavor will differ slightly but still be delicious.
How do I make this tuna salad extra flavorful?
Add a pinch of smoked paprika or a dash of hot sauce for depth, or stir in 1 tablespoon of chopped pickles for tangy crunch. For umami, try adding 1 teaspoon of soy sauce or Worcestershire sauce. Fresh herbs like parsley or chives also brighten the flavor. Always taste as you go—small adjustments make a big difference!
