Ingredients for weight watchers tuna salad
Simple swaps make this tuna salad light yet packed with satisfying protein—no heavy mayo here.
| Ingredient | Amount | Notes |
|---|---|---|
| Canned Tuna in Water 🐟 | 1 ½ cans | Drained, high-quality preferred |
| Non-Fat Plain Greek Yogurt 🥛 | ½ cup | Full-fat for creaminess if preferred |
| Light Mayonnaise 🥫 | 2 tbsp | Or sub Greek yogurt for fewer calories |
| Dijon Mustard 🍯 | 1 tsp | For tangy depth |
| Red Onion 🧅 | ¼ cup | Finely diced, fresh preferred |
| Celery Stalks 🥬 | 2 whole | Finely chopped, for crunch |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground preferred |
| Dried Dill 🌿 | ½ tsp | Or sub fresh dill at 1 tsp |
| Capers 🍈 | 1 tsp | Optional, for briny kick |
| Iceberg Lettuce 🥬 | 4 cups | Shredded, for serving |
| Whole Grain Crackers 🍞 | 12 pieces | For serving, optional |
The Greek yogurt is the game-changer here. Non-fat works best for Weight Watchers points, but trust me on the full-fat version if you're craving extra creaminess. I grab Fage or Chobani from the store—they’re consistent and stay fresh longer. The tuna? Wild-caught or light tuna in water keeps calories down. Skip the oil-packed kind unless you're going for a richer flavor. For the celery, I always buy the pre-cut bags from Trader Joe's—saves time and avoids the crunchy ends. Fresh dill is ideal, but dried works in a pinch (just use half the amount).
No Greek yogurt? Light mayo or avocado mash gets you close, but the yogurt keeps it lighter. Hate celery? Extra red onion or pickles add crunch without the calories. The capers are optional but worth it—they add that classic briny tang. If you’re watching points, skip the crackers and serve it over lettuce instead. The Dijon mustard is non-negotiable though—it’s what makes this taste like real tuna salad, not just canned fish with mayo. For extra flavor without extra points, add a pinch of smoked paprika or a dash of hot sauce.
This keeps beautifully in the fridge for 3-4 days if stored in an airtight container. I portion mine into small containers for easy grab-and-go lunches. The texture stays perfect—no soggy lettuce or mushy celery. For meal prep, double the batch and freeze half in an ice cube tray. Thaw overnight in the fridge and mix with a splash of lemon juice to revive the flavor. The lemon juice is key here—add it just before serving so the salad stays bright and fresh.

Step-by-step instructions for Weight Watchers tuna salad recipe
This tuna salad keeps calories in check while packing in flavor and protein—perfect for meal prep.
Drain and Flake the Tuna
Open the 1.5 cans of canned tuna in water and drain them thoroughly over a bowl, pressing down gently on the fish with a fork to remove excess liquid. Transfer the drained tuna to a large mixing bowl. I like to break it up into flakes with my fork—this helps it blend smoothly with the other ingredients and creates that classic tuna salad texture.
The reason we drain so well is that watery tuna salad gets soggy fast. You want the mixture to hold together nicely when you spread it on crackers or lettuce wraps later. If your tuna comes in oil instead of water, drain that too and pat it dry with paper towels.
Mix the Creamy Base
Add the 0.5 cup non-fat plain Greek yogurt, 2 tablespoons light mayonnaise, and 1 teaspoon Dijon mustard to the bowl with the tuna. Using a fork or small spatula, gently fold everything together until just combined. I like to mix gently at first—this keeps the tuna flakes intact for that satisfying texture.
Here's the thing—Greek yogurt replaces most of the mayo, cutting calories while keeping it creamy. If you want even fewer calories, you could swap in more yogurt, but the mayo adds that classic richness. Taste the mixture now—it should be tangy but mild. If it needs more zing, we'll add the lemon juice next.
Add the Fresh Vegetables and Seasonings
Finely dice the 0.25 cup red onion and chop the 2 whole celery stalks into small pieces. Add these to the bowl along with the 1 tablespoon lemon juice, 0.5 teaspoon salt, 0.25 teaspoon black pepper, 0.5 teaspoon dried dill, and 1 teaspoon capers. Stir everything together until the vegetables are evenly distributed and the seasonings are fully incorporated.
Don't skip the celery—it adds that classic crunch that makes tuna salad special. The red onion gives a bright bite, while the lemon juice brightens everything up. The capers add a briny kick that ties all the flavors together. If you're using fresh dill instead of dried, add 1 teaspoon—it's more potent.
Chill and Serve
Cover the bowl and refrigerate the tuna salad for at least 30 minutes before serving. This chilling time lets the flavors meld together and makes the texture even creamier. I usually make it the night before so it's ready to grab for lunch the next day—it actually tastes better after resting.
When you're ready to serve, assemble your tuna salad with 4 cups shredded iceberg lettuce for a light wrap or with 12 whole grain crackers for a satisfying snack. The lettuce adds freshness, while the crackers give you a bit of crunch and fiber. If you're watching points, skip the crackers and use the lettuce as your base.
Customize and Enjoy
Taste your tuna salad one more time and adjust the seasoning if needed. Maybe it needs a pinch more salt or a squeeze of lemon. The beauty of this recipe is how flexible it is—you can make it as light or as rich as you like by adjusting the yogurt-to-mayo ratio.
This tuna salad keeps well in the fridge for up to 3 days, making it perfect for meal prep. Pack it in small containers for easy lunches or use it as a filling for lettuce wraps, sandwiches, or even as a topping for baked potatoes. The key is keeping it chilled until you're ready to eat—this ensures it stays fresh and delicious.
Pro Tips For Making Weight Watchers Tuna Salad
- Drain and press the tuna: Drain the tuna in a fine-mesh strainer, then press it gently with the back of a spoon to squeeze out excess water. I learned this the hard way—wet tuna makes the salad soggy, and nobody wants a watery mess when you’re aiming for clean, creamy texture.
- Mix in the onion last: Finely dice the red onion and fold it into the salad just before serving. Raw onion softens quickly in yogurt and mayo, losing its bite—adding it last keeps that sharp crunch you actually want.
- Use cold ingredients only: Take the canned tuna, Greek yogurt, and mayo straight from the fridge—no room-temperature shortcuts. Cold ingredients blend smoother and stay stable longer, so your salad doesn’t turn grainy or separate halfway through the day.
- Balance the mayo-to-yogurt ratio: Start with 1 part light mayo to 2 parts Greek yogurt, then adjust to taste. Too much mayo makes it heavy; too much yogurt can taste bland. Taste as you go—this is where the magic happens, and you’ll find your sweet spot fast.
Best sauces and condiments for this dish
Greek Yogurt Swap
Replace mayo with non-fat Greek yogurt—it’s the secret to keeping calories low while maintaining creaminess. I use ½ cup Fage 0% for its tangy flavor and protein boost. For a richer texture, blend in 1 tablespoon light mayo or avocado.
The yogurt also adds a subtle protein kick that keeps you full longer. Just remember to taste as you mix—sometimes you need a splash of lemon juice to balance the tang.
Dijon Mustard Boost
That 1 teaspoon Dijon mustard is non-negotiable—it adds depth without calories. I grab the Maille brand from the store because it’s smooth and well-seasoned. If you prefer a sharper kick, add ½ teaspoon hot sauce or a pinch of smoked paprika.
The mustard cuts through the richness of the yogurt and mayo, making each bite brighter. Trust me, skipping this step leaves your tuna salad tasting flat.
Bright Citrus Finish
A squeeze of 1 tablespoon fresh lemon juice keeps this salad vibrant and fresh. I always use freshly squeezed juice—it makes a world of difference compared to bottled. If you’re prepping ahead, add the lemon juice just before serving to prevent the salad from becoming watery.
For extra zing, try lime juice instead, or mix both for a tropical twist. The acidity also helps balance any saltiness from the capers or red onion.
Caper Crunch
Those 1 teaspoon capers bring a briny, umami punch that elevates the whole dish. I use the non-pasteurized kind from the Mediterranean section at my local grocery store—they’re packed in brine, not oil. If you’re watching sodium, rinse them first or use ½ teaspoon.
For a smoky variation, swap in 1 teaspoon chopped cornichons or a dash of smoked sea salt. The capers add texture and a salty contrast that makes the salad irresistible.
Herb Infusions
Fresh dill is the classic choice, but don’t be afraid to experiment. Try 1 teaspoon chopped chives for a milder flavor or ½ teaspoon dried tarragon for an elegant twist. If you’re using fresh herbs, add them just before serving so they stay vibrant.
For a Mediterranean vibe, mix in ½ teaspoon dried oregano with the capers. The herbs not only add freshness but also help mask any fishy notes in the tuna.
Sweet Heat Balance
For a sweet-and-spicy kick, stir in ½ teaspoon honey or maple syrup with the lemon juice. The sweetness balances the tang and salt perfectly. If you love heat, add ¼ teaspoon cayenne pepper or a few drops of hot sauce.
I keep a small bottle of Cholula on hand for this—it adds a smoky depth that pairs beautifully with the tuna. Adjust to taste, but remember: small amounts go a long way.

Frequently asked questions
Can I use oil-packed tuna instead of water-packed?
You can, but it will add extra calories and fat. Drain the oil completely and pat the tuna dry with paper towels to keep the recipe light. For every 2 tablespoons of oil removed, you'll save about 50 calories. If you love the flavor, use just 1 can of oil-packed tuna instead of 1.5 cans of water-packed to balance the points.
How do I make this tuna salad extra creamy without adding calories?
Blend ¼ cup silken tofu or 2 tablespoons mashed avocado into the Greek yogurt before mixing. Both add creaminess with minimal calories—silken tofu contributes 10 calories per tablespoon, while avocado adds healthy fats that keep you full. Just add them at the same time as the yogurt in Step 2.
What are the best ways to serve this tuna salad on Weight Watchers?
Try these zero-point bases: 4 cups mixed greens for a light salad, 2 large lettuce leaves for wraps, or 1 cup cucumber slices for a refreshing twist. For 1-2 points, add 5 whole grain crackers or ½ cup cooked quinoa. Always check the latest WW app for current point values on your toppings.
Why does my tuna salad get watery after chilling?
This happens when you don't drain the tuna well or use too much liquid ingredients. Always press the tuna thoroughly with a fork to remove excess water, and measure your Greek yogurt and lemon juice precisely. If it still gets watery, add 1 tablespoon extra celery or diced bell pepper—they absorb moisture and add crunch.
Can I make this ahead of time for meal prep?
Store in an airtight container for up to 3 days in the fridge. For longer storage, freeze portions in ice cube trays, then transfer to a bag. Thaw overnight in the fridge and stir in a splash of lemon juice before serving. The flavors actually meld better after resting, but add fresh herbs just before eating.
