This tuna salad redefines what a healthy lunch can be. I replaced traditional mayo with Greek yogurt, creating a protein-packed base that’s creamy without the guilt.
The addition of crisp celery, red onion, and cucumber introduces fresh crunch and vibrant texture. Each bite delivers balanced flavor without compromising on the classic tuna salad experience.
What sets this version apart is its ability to stay fresh longer than mayo-based alternatives. The yogurt keeps everything moist while maintaining a light, clean finish.
Perfect for meal prep, this salad holds up beautifully in the fridge for up to three days. Serve it in lettuce wraps, on whole grain bread, or straight from the bowl.
Ingredients for Healthy Tuna Salad Recipe No Mayo
Pantry staples plus fresh veggies make this light and bright lunch.
| Ingredient | Amount | Notes |
|---|---|---|
| Canned Tuna in Water 🐟 | 2 cans | Drained and flaked |
| Plain Greek Yogurt 🥛 | 1 cup | Full-fat for creaminess |
| Celery Stalks 🌿 | 3 whole | Finely diced for crunch |
| Red Onion 🧅 | ½ whole | Small dice for bite |
| English Cucumber 🥒 | 1 whole | Seeds removed, diced |
| Fresh Lemon Juice 🍋 | 2 tbsp | Brightens the flavor |
| Dijon Mustard 🟡 | 1 tbsp | Adds tangy depth |
| Fresh Dill 🌿 | 2 tbsp | Chopped, or 2 tsp dried |
| Garlic Cloves 🧄 | 2 cloves | Minced for aroma |
| Sea Salt 🧂 | ½ tsp | Adjust to taste |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Olive Oil 🫒 | 1 tbsp | Extra-virgin for richness |
The tuna is the base, so wild-caught in water is what I grab from Whole Foods or Trader Joe’s—it’s firmer and less fishy. Greek yogurt is the magic here; Fage or Chobani full-fat gives that creamy texture without the mayo heaviness. Celery should be crisp (bendy stalks = old), and red onion adds just enough bite without overpowering. Fresh dill is ideal, but dried works in a pinch at a third the amount.
No Greek yogurt? Sour cream or plain yogurt (strain it first) can step in. Skip the red onion? Green onions or shallots are milder. Want extra crunch? Toss in diced bell peppers or radishes. The Dijon mustard is flexible too—yellow mustard or whole-grain both work. If you’re out of fresh lemon, bottled is fine (just use a little less).
This keeps 3-4 days in the fridge, sealed tight. The flavors actually improve overnight. Don’t freeze it—tuna gets weirdly spongy. Best served chilled, so it’s perfect for meal prep.

Step-by-Step Instructions for Healthy Tuna Salad No Mayo
This Greek yogurt version comes together quickly with fresh, crunchy ingredients.
Step 1: Prep Vegetables for Crunch and Flavor
Start by finely dicing the 3 whole Celery Stalks to create a consistent crunch throughout the salad. I like to remove any stringy bits first for a more pleasant texture. Then, take the 0.5 whole Red Onion and small-dice it for a mild bite that doesn’t overpower.
Next, halve the 1 whole English Cucumber lengthwise and scrape out the seeds with a spoon before dicing. This prevents excess water from making the salad soggy. Place all the prepped vegetables in a large bowl—this ensures even distribution of flavors later.
Step 2: Drain and Flake 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 as much liquid as possible—this keeps the salad from getting watery. Transfer the drained tuna to a plate and flake it with a fork into smaller, bite-sized pieces.
I always check for any stray bones or skin pieces at this stage, even though they’re rare. The flaked tuna should look light and airy, not clumped together. Once prepped, add it to the bowl with the vegetables.
Step 3: Whisk Together the Creamy Dressing
In a small bowl, combine the 1 cup Plain Greek Yogurt, 2 tbsp Fresh Lemon Juice, 1 tbsp Dijon Mustard, 1 tbsp Olive Oil, and 2 cloves Garlic Cloves (minced). Whisk vigorously until the mixture is smooth and fully emulsified—this takes about 30 seconds of consistent whisking.
The lemon juice and mustard will brighten the yogurt’s tang, while the olive oil adds a silky richness. Stir in the 2 tbsp Fresh Dill, 0.5 tsp Sea Salt, and 0.5 tsp Black Pepper to finish the dressing. Taste and adjust seasoning if needed before pouring it over the tuna and vegetables.
Step 4: Combine and Chill for Best Flavor
Pour the dressing over the tuna and vegetable mixture. Gently fold everything together with a spatula until all ingredients are evenly coated. The yogurt should cling to the tuna and veggies without pooling at the bottom of the bowl.
Cover the bowl with plastic wrap and refrigerate for at least 30 minutes. This chilling time allows the flavors to meld and the salad to thicken slightly. If you’re in a hurry, 15 minutes will work, but the longer it sits, the better it tastes.
Serve chilled over greens, in a wrap, or with whole-grain crackers. The salad keeps well in the fridge for up to 3 days in an airtight container.
Pro Tips For Making Healthy Tuna Salad Recipe No Mayo
- Drain the Tuna Well: Press the tuna between paper towels after draining—excess water makes the salad watery and dilutes the Greek yogurt’s creaminess.
- Salt the Cucumber: Sprinkle diced cucumber with a pinch of salt and let it sit for 5 minutes before adding, then squeeze out the liquid. Sounds weird, but it works: keeps your salad from getting soggy.
- Use Full-Fat Yogurt: I learned this the hard way—low-fat Greek yogurt can taste tangy and thin in this recipe. Full-fat balances the flavors and clings better to the tuna and veggies.
- Soak the Onion: Toss the diced red onion in cold water for 10 minutes while you prep the rest. Takes the harsh bite away without losing that crunch.
