The smell of fresh herbs and zest fills the air as tender, flaky albacore tuna combines with crisp celery and bright, briny capers. It looks like every classic tuna salad you grew up with, but there is one massive difference: the heavy, cloying weight of store-bought mayonnaise is completely gone.
Instead, a silky, luxurious dressing made from low-fat Greek yogurt, cold-pressed extra virgin olive oil, sharp Dijon mustard, and freshly squeezed lemon juice coats every bite. This velvety blend mirrors the rich mouthfeel of traditional mayo while lifting the seafood with a clean, vibrant taste that keeps you coming back for more.
Why is The No-Mayo Tuna Salad Hack So Good?
- Protein Powerhouse: Swapping mayo for Greek yogurt adds over 10 grams of extra high-quality protein per serving to support muscle repair and keep you full for hours.
- Zero Seed Oils: Processed soybean and canola oil base is replaced with heart-healthy monounsaturated fats from cold-pressed olive oil.
- Clean, Vibrant Flavor: Fresh lemon juice and Dijon mustard cut through seafood richness without masking it.
- Unbeatable Crunch: Dice of crisp celery, shallots, and briny capers create texture in every forkful.
Ingredients
- Canned Wild Albacore Tuna in Water — dense, clean protein base for maximum flavor and nutrition (340 g)
- Plain 2% Greek Yogurt — rich, probiotic-dense base providing velvety creaminess without heavy fats (120 g)
- Extra Virgin Olive Oil — rich monounsaturated fats providing a glossy mouthfeel and heart health benefits (15 ml)
- Dijon Mustard — sharp, tangy emulsifier that adds depth and classic bite (15 g)
- Fresh Lemon Juice — bright acidity that cleanses the palate and cuts through rich tuna (15 ml)
- Finely Diced Celery — crisp, watery crunch that contrasts with tender tuna (80 g)
- Finely Diced Red Onion — subtle pungent sweetness and vibrant color (40 g)
- Drained Capers — salty, floral bursts that enhance seafood flavors (20 g)
- Fresh Dill — aromatic, sweet herb notes that elevate simple ingredients (10 g)
- Sea Salt and Black Pepper — essential minerals to heighten every natural flavor component (to taste)
Step-by-Step Instructions
- Drain the canned tuna completely using a fine-mesh strainer, using the back of a fork to press out all excess liquid so the salad does not become watery.
- Whisk the plain Greek yogurt, extra virgin olive oil, Dijon mustard, and fresh lemon juice together in a medium mixing bowl until the dressing is smooth and fully emulsified.
- Add the thoroughly drained tuna, diced celery, red onion, capers, and chopped fresh dill directly into the bowl with the creamy dressing.
- Flake the tuna gently with a fork while folding all ingredients together until everything is coated uniformly, leaving nice texture rather than over-mashing.
- Season with sea salt and freshly cracked black pepper, taste, and adjust with extra lemon juice or herbs if desired before serving.
Tips for the Best No-Mayo Tuna Salad
- Dry the tuna well: Moisture is the enemy of creamy tuna salad. Pressing the tuna dry ensures the Greek yogurt dressing clings to every flake rather than slipping off.
- Choose whole milk or 2% Greek yogurt: Non-fat yogurt can be overly watery and excessively tart. A small amount of fat yields a luscious, mayo-like emulsion.
- Let it chill: Allow the assembled tuna salad to rest in the refrigerator for 15–20 minutes before serving so the flavors meld together harmoniously.
Storage and Freezing Instructions
- Refrigerator: Store in a sealed glass container in the fridge for up to 3 days. Stir gently before serving if any natural juices separate.
- Freezing: Freezing is not recommended. Dairy-based dressings and fresh, high-water vegetables like celery break down and become soggy upon thawing.
No-Mayo Tuna Salad Your Way
- Dairy-Free Alternative: Replace Greek yogurt with 120 g of ripe, mashed avocado or blended silken tofu for a rich, plant-based texture.
- Sub the Capers: If capers aren't your favorite, swap them for an equal weight of finely chopped dill pickles or green olives.
- Add Extra Greens: Fold in a handful of baby arugula or chopped English cucumber for added hydration and micronutrients.
Make Ahead
You can easily meal-prep this dish! Whisk the dressing components together in advance and store in a jar for up to 5 days. For maximum crunch, chop the vegetables and store them separately, combining everything with the tuna the night before your busy day.

Frequently Asked Questions
Can I use tuna packed in oil instead of water?
Yes! Tuna packed in olive oil works wonderfully and adds extra healthy fats. Just drain it well before mixing into the dressing and reduce the extra virgin olive oil in the recipe to 5 ml.
Does this taste like Greek yogurt?
The tartness of Greek yogurt is neutralized by the combination of Dijon mustard, lemon juice, and savory capers. It creates a rich, balanced flavor profile that tastes remarkably like high-end deli tuna salad.
How should I serve this no-mayo tuna salad?
Serve it scooped over a bed of crisp butter lettuce, stuffed into half an avocado, rolled into a high-fiber whole-wheat wrap, or served alongside whole-grain seeded crackers for a balanced meal.
