This lightened-up tuna salad proves you can enjoy a creamy, satisfying lunch without the guilt. I replaced traditional mayo with Greek yogurt, cutting fat while adding protein and a subtle tang that enhances the tuna’s natural flavor.
The texture remains rich and spreadable, but the dish feels fresher and more balanced. A squeeze of lemon brightens the yogurt base, while crisp celery and red onion add necessary crunch and bite to every forkful.
Ready in under 10 minutes, this salad is ideal for quick lunches or meal prep. It holds up well in the fridge, making it a reliable choice for packed lunches throughout the week.
Serve it on whole-grain bread, over mixed greens, or with cucumber slices for a light, protein-packed meal that satisfies without heaviness.
Ingredients for Low Fat Tuna Salad Recipe with Greek Yogurt
Light, creamy, and packed with protein for a guilt-free lunch everyone loves.
| Ingredient | Amount | Notes |
|---|---|---|
| Canned Tuna in Water 🐟 | 2 cans | Drained and flaked |
| Plain Greek Yogurt 🥛 | 1 cup | Full-fat or 2% for creaminess |
| Celery 🥬 | 1 whole | Finely diced for texture |
| Red Onion 🧅 | ¼ whole | Finely diced for bite |
| Fresh Lemon Juice 🍋 | 2 tbsp | Brightens the flavor |
| Dijon Mustard 🟡 | 1 tbsp | Adds tangy depth |
| Fresh Dill 🌿 | 2 tbsp | Chopped, or 2 tsp dried |
| Salt 🧂 | ½ tsp | Adjust to taste |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground preferred |

| Cucumber 🥒 | 1 whole | Sliced, for serving |
| Whole-Grain Bread 🍞 | 8 slices | For serving sandwiches |
The Greek yogurt is key here—Chobani or Fage are my go-to brands for that rich, tangy base. Look for plain, unsweetened to keep the focus on the tuna. For the tuna, wild-caught in water (not oil) gives you cleaner flavor. Most grocery stores carry decent options, but Trader Joe’s has great canned tuna at a good price. Fresh dill from the produce section brightens everything up (that pre-cut stuff in tubes? Skip it).
No Greek yogurt? Substitute plain skyr—it’s got the same thick texture. Out of fresh dill? Dried dill at one-third the amount works, or use fresh parsley if that’s what you’ve got. The red onion can be swapped for green onions if you prefer milder bite. Want more crunch? Add some chopped bell pepper or apple. The Dijon mustard is flexible too—yellow mustard in a pinch.
This keeps beautifully in the fridge for up to 4 days—actually tastes better after a day. Store in an airtight container with a paper towel on top to absorb extra moisture. It’s perfect for meal prep: make a big batch on Sunday and you’re set for lunches all week. Serve it cold or at room temp (I prefer it slightly chilled).

Step-by-Step Instructions for Low Fat Tuna Salad With Greek Yogurt
This method delivers a creamy, flavorful salad that’s light yet satisfying for lunch.
Step 1: Prep and Drain the Tuna
Open the 2 cans Canned Tuna in Water and drain them thoroughly in a fine-mesh strainer. Press gently with a spoon to remove excess liquid—this prevents a watery salad. Transfer the tuna to a large mixing bowl and flake it with a fork until it’s in even, bite-sized pieces.
I like to let the drained tuna sit for a minute to ensure all the water drips out. You’ll notice the difference in texture when you take this extra step.
Step 2: Combine Wet Ingredients and Aromatics
To the bowl with the tuna, add the 1 cup Plain Greek Yogurt, 2 tbsp Fresh Lemon Juice, 1 tbsp Dijon Mustard, 0.5 tsp Salt, 0.25 tsp Black Pepper, and 0.25 tsp Garlic Powder. Stir gently until fully combined—the yogurt will create a creamy base without the heaviness of mayo.
Next, fold in the finely diced 1 whole Celery and 0.25 whole Red Onion. These add a fresh crunch and subtle sharpness that balances the richness of the tuna. The mixture should look evenly coated and slightly glossy.
Step 3: Finish with Fresh Herbs and Chill
Chop the 2 tbsp Fresh Dill finely and stir it into the salad. The dill brightens the flavor and pairs perfectly with the lemon and mustard. Taste and adjust the salt if needed, but remember the flavors will meld as it chills.
Cover the bowl and refrigerate for at least 30 minutes to let the flavors develop. This resting time is key—it allows the ingredients to marry and the salad to thicken slightly.
Step 4: Serve on Bread with Cucumber
Slice the 1 whole Cucumber thinly and set aside. Give the salad one final stir—if it seems thick, a splash of water or extra lemon juice can loosen it slightly. Spoon the mixture onto the 8 slices Whole-Grain Bread, dividing it evenly for 4 sandwiches.
Layer the cucumber slices on top for a refreshing crunch. Serve immediately, or wrap the sandwiches tightly for a grab-and-go lunch. The bread stays soft, and the flavors taste even better after a short rest.
Pro Tips For Making Low Fat Tuna Salad Recipe With Greek Yogurt
- Drain the Tuna Well: Press the drained tuna between paper towels to remove every last drop of water—I learned this the hard way after my first batch turned into soup.
- Use Full-Fat Yogurt: Despite the name, 2% Greek yogurt actually holds up better than non-fat and keeps the salad from tasting watery.
- Soak the Onion: Toss the diced red onion in cold water for 5 minutes to mellow the bite, or your salad will taste like raw onion overpowers everything.
- Add Lemon Last: Stir in the fresh lemon juice right before serving—adding it too early makes the celery go limp.
Common Mistakes When Making low fat tuna salad recipe with greek yogurt
Over-Draining the Tuna
While draining is essential, pressing too hard can make your salad dry. I gently squeeze the tuna in the strainer for 5-10 seconds—just enough to remove excess water without stripping away all moisture. You want some natural juices to keep the texture creamy. 💡
Skipping the Chill Time
Rushing to serve immediately means missing out on flavor development. I always refrigerate for at least 30 minutes—this lets the yogurt absorb the seasonings and the dill infuse throughout. The texture also improves, becoming more cohesive.
Using Watery Yogurt
Thin, runny yogurt creates a soggy salad. I use full-fat Greek yogurt—brands like Chobani or Fage are ideal. If your yogurt seems watery, strain it in a fine-mesh sieve for 10 minutes before mixing to thicken it naturally.
Over-Seasoning Early
Salting before chilling can lead to over-seasoning as flavors concentrate. I add just ½ tsp salt initially, then taste after chilling and adjust. The lemon and mustard also enhance flavor without needing extra salt.
Dicing Vegetables Too Large
Big celery or onion chunks disrupt the creamy texture. I finely dice both to ⅛-inch pieces so they distribute evenly. This ensures every bite has balanced flavor and crunch without overwhelming the tuna.
Ignoring Tuna Quality
Oil-packed tuna or poor-quality brands can make your salad greasy or fishy. I always choose water-packed wild-caught tuna—it has cleaner flavor and better texture. Trader Joe’s or Safe Catch are my go-to brands for consistent quality.

Frequently Asked Questions
Can I use regular yogurt instead of Greek?
Strain regular yogurt for 10 minutes to thicken it first. Greek yogurt’s thickness is key for that creamy texture without excess liquid.
How long does this keep in the fridge?
It stays fresh for up to 4 days in an airtight container. The flavors actually improve after 24 hours.
What can I serve this with besides bread?
Try cucumber slices, crackers, or over mixed greens. It also works great stuffed into avocado halves for a low-carb option.
How can I make this even lower in fat?
Use non-fat Greek yogurt and skip the garlic powder if it contains oil. Every little bit helps while keeping it flavorful.
