Fresh herbs and a bright squeeze of lemon transform simple canned tuna into a zesty, herb-infused dish that’s satisfying yet light. It comes together in 5 minutes with pantry staples.
Ingredients for Low Fat Tuna Salad
Pantry staples plus fresh herbs make this dish sing in minutes.
| Ingredient | Amount | Notes |
|---|---|---|
| Canned Tuna in Water 🐟 | 2 cans | Drained and flaked |
| Plain Greek Yogurt 🥛 | ¾ cup | Non-fat or low-fat preferred |
| Celery Stalks 🌿 | 2 whole | Finely diced for crunch |
| Red Onion 🧅 | ¼ whole | Minced for sharp bite |
| Fresh Dill 🍃 | ¼ cup | Chopped, stems removed |
| Fresh Parsley 🌿 | ¼ cup | Chopped, flat-leaf variety |
| Lemon 🍋 | 1 whole | Zested and juiced |
| Dijon Mustard 🟡 | 1 tbsp | For tangy depth |
| Garlic Cloves 🧄 | 2 cloves | Minced for aroma |
| Capers 🫒 | 2 tbsp | Drained, optional for briny kick |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
The tuna is the base, so wild-caught in water is ideal (less oil, cleaner flavor). Trader Joe’s or Whole Foods have great options. Greek yogurt needs to be thick—Fage 2% or Chobani non-fat work perfectly. Fresh herbs are non-negotiable here; dried just won’t cut it. Grab dill and parsley from the farmers market if you can—they’re night-and-day better than grocery store bunches.
No Greek yogurt? Low-fat sour cream gets you close but less protein. Skip the capers? Chopped pickles or olives add that briny pop. Out of fresh dill? Fresh tarragon at half the amount works, but the flavor shifts. The Dijon can be swapped for whole-grain mustard (more texture) or yellow mustard (milder). Red onion too strong? Green onions or shallots are gentler.
This keeps 3-4 days in the fridge—actually tastes better after 24 hours once flavors meld. Don’t freeze (yogurt separates). Perfect for meal prep: portion into containers with whole-grain crackers or greens. That’s it.

Step-by-Step Instructions for Low Fat Tuna Salad
Here’s my go-to method for a bright, herb-packed creation without heavy mayo weighing it down.
Step 1: Drain and Flake the Canned Tuna in Water
Open the 2 cans Canned Tuna in Water and drain them thoroughly in a fine-mesh strainer. Press the tuna gently with a spoon to remove any excess liquid—this prevents a watery final dish.
Transfer the drained tuna to a large mixing bowl and flake it with a fork until it’s broken into small, even pieces. You want a consistent texture throughout, not large clumps. This step ensures every bite has the perfect balance of tuna and flavor.
Step 2: Prepare the Aromatics and Herbs
Finely dice the 2 whole Celery Stalks and mince the 0.25 whole Red Onion—you’ll want these pieces small enough to blend seamlessly into the salad. Chop the 0.25 cup Fresh Dill and 0.25 cup Fresh Parsley, removing any thick stems from the dill first.
Mince the 2 cloves Garlic Cloves and add them to the bowl with the celery and onion. The garlic should be fine enough to distribute its aroma evenly without overwhelming any single bite. Drain the 2 tbsp Capers if you’re using them, as their briny kick pairs perfectly with the tuna.
Step 3: Zest and Juice the Lemon
Zest the 1 whole Lemon first, then cut it in half and juice it. The zest adds a bright, citrusy punch, while the juice brings acidity to balance the richness of the other ingredients.
Add the zest and 1-2 tbsp of lemon juice to the bowl with the aromatics. The exact amount of juice depends on your preference, but start with 1 tbsp and adjust as needed. This step is crucial for that zesty infusion promised in the title.
Step 4: Mix in the Creamy Base and Seasonings
Add the 0.75 cup Plain Greek Yogurt and 1 tbsp Dijon Mustard to the bowl. The yogurt replaces mayo for a lighter texture, while the mustard adds a tangy depth that ties everything together.
Sprinkle in the 0.5 tsp Salt and 0.5 tsp Black Pepper, then fold all the ingredients together with a spatula. Mix until just combined—overworking can make the salad dense. Taste and adjust the lemon juice or salt if needed.
Step 5: Chill and Serve
Cover the bowl and refrigerate for at least 30 minutes to let the flavors meld. This resting time allows the herbs and aromatics to infuse the salad fully, creating a cohesive, vibrant dish.
Serve chilled on whole-grain crackers, in a sandwich, or over a bed of greens. The texture should be creamy but not heavy, with bright herbal notes and a refreshing citrus finish. This makes 4 servings of perfectly balanced, low-fat tuna salad.
Pro Tips For Making Low Fat Tuna Salad
- Drain the Tuna: Press the canned tuna in a fine-mesh strainer for 30 seconds to remove every last drop of water—I learned this the hard way after my first few batches turned out watery.
- Chill the Yogurt: Use cold Greek yogurt straight from the fridge; it binds better with the tuna and keeps the salad from getting greasy.
- Fine Dice the Onion: Soak the minced red onion in cold water for 5 minutes to mellow the sharpness, then drain well—no one wants a harsh bite in their tuna salad.
- Fold, Don’t Stir: Gently fold the ingredients with a spatula instead of stirring to keep the tuna chunks intact and the texture pleasant.
Regional Styles of low fat tuna salad
Mediterranean Style
In Greece, they add Kalamata olives and fresh oregano for a briny, earthy twist. I use ½ cup chopped olives and 1 tbsp dried oregano with the base recipe. A drizzle of extra-virgin olive oil before serving enhances the Mediterranean vibe. This version pairs perfectly with pita bread. 🌟
French Niçoise
The Niçoise approach skips the creamy base entirely. Combine flaked tuna with cherry tomatoes, green beans, and hard-boiled eggs. Dress with 2 tbsp olive oil and 1 tbsp red wine vinegar instead of yogurt. It’s lighter but packed with vibrant flavors.
Southern US
Down South, they love a little sweetness. I mix in 2 tbsp sweet pickle relish and 1 tsp paprika for warmth. Serve it on whole wheat bread with lettuce for a satisfying lunch. The relish replaces capers for a milder, sweeter briny note.
Asian Fusion
For an Asian twist, swap the herbs for cilantro and mint. Add 1 tbsp grated ginger and 1 tbsp soy sauce to the yogurt base. Serve in butter lettuce cups with a sprinkle of sesame seeds. This version is refreshing and light. ✨
Midwest Classic
In the Midwest, they keep it simple and hearty. I add ½ cup diced cucumber and ¼ cup shredded carrots for extra crunch. Serve it on a bed of iceberg lettuce with a side of whole-grain crackers. Perfect for a quick, no-fuss meal.

Frequently Asked Questions
Can I use canned tuna in oil instead of water?
Drain and rinse it well to remove excess oil. This reduces fat but may slightly dilute flavor. For best results, stick with water-packed for the cleanest taste.
How long does this keep in the fridge?
It stays fresh for 3-4 days in an airtight container. The flavors actually improve after 24 hours as they meld together. Don’t freeze it, as yogurt separates.
What can I substitute for Greek yogurt?
Low-fat sour cream works well, though with less protein. For a dairy-free option, try mashed avocado for creaminess, but use it fresh.
Can I make this ahead for a party?
Prepare it the night before and chill. Add fresh herbs right before serving to keep them vibrant. This dish travels well in a cooler.
