Quick High-Protein Tuna Salad with Greek Yogurt

When you need a no-cook lunch that actually keeps you full, this tuna salad with Greek yogurt is the one I reach for. It takes about 10 minutes and swaps the usual mayo for tangy yogurt, so it tastes lighter but stays creamy.

Pile it on toast or scoop it with crackers, and you have a protein-packed meal that feels fresh, not heavy.

What Makes This Tuna Salad a Keeper

I love that this version doesn’t leave me feeling sluggish afterward. The Greek yogurt gives it a bright, clean tang and enough creaminess that I never miss the mayo.

It’s quick to throw together, and you can make a batch on Sunday for lunches all week. The celery and red onion stay crunchy, so the texture holds up even after a day in the fridge.

Ingredients

• 2 (5 oz) cans tuna, drained: solid white albacore for a firmer texture, or chunk light for a softer, more affordable option
• 1/3 cup plain Greek yogurt: full-fat or 2% both work well; nonfat can be used but might give a slightly thinner, grainy result
• 1/4 cup finely diced celery: adds a fresh crunch
• 2 tbsp minced red onion: soak in cold water for 5 minutes if you want a milder bite
• 1 tbsp chopped fresh dill: (or 1 tsp dried): fresh is brighter, but dried works in a pinch
• 1 tsp Dijon mustard: optional, but it deepens the flavor nicely
• 1 tsp fresh lemon juice: brightens the whole salad
• salt and black pepper: to taste

Variations / Substitutions

• No dill?: Use fresh parsley or chives instead; they each bring a different fresh note without overpowering the tuna.
• Add extra crunch: Stir in 2 tbsp chopped toasted almonds or sunflower seeds right before serving.
• Make it dairy-free: Swap the Greek yogurt for an equal amount of unsweetened plain coconut or almond milk yogurt.
• Go extra creamy: Fold in half a mashed avocado along with the yogurt, and reduce the yogurt by 2 tbsp.
• Swap the protein: This recipe works equally well with one 14 oz can of drained salmon.

How to Make Tuna Salad with Greek Yogurt

Step 1: Whisk the Dressing

In a medium bowl, whisk together the 1/3 cup Greek yogurt, 1 teaspoon Dijon mustard, 1 teaspoon lemon juice, and a pinch of salt and pepper. Stir in the 1 tablespoon chopped dill. This takes about 30 seconds, and the dressing should taste tangy and a little sharp.

Step 2: Fold in the Tuna and Crunch

Break the drained tuna into small flakes with a fork and add it to the bowl along with the 1/4 cup celery and 2 tablespoons red onion. Fold everything together gently until the tuna is evenly coated. You want the tuna in bite-sized pieces, not pulverized, so the salad has some body and doesn’t turn into a paste.

Step 3: Scoop Onto Toast and Serve

Scoop the tuna salad generously onto toasted whole-grain bread, butter lettuce cups, or sturdy crackers. A final crack of black pepper on top makes it look and taste fresh. Serve right away, or chill for 10 minutes if you have time—it firms up just a little and the flavors meld.

A Few Quick Tips

• Press the tuna firmly with the can lid after opening to remove as much liquid as possible; any leftover water will make the salad soggy.
• If you’re packing this for lunch, keep the tuna salad in a separate container and spoon it onto bread or crackers right before eating to avoid a soggy sandwich.
• Taste and adjust the salt after mixing—canned tuna varies widely in sodium, and some brands need a more generous pinch than others.
• A squeeze of extra lemon juice just before serving wakes up the whole bowl.

Storing Leftover Tuna Salad

• Refrigerate: Store in an airtight container for up to 3 days. The salad keeps well and often tastes even better on day two after the dill and onion have had time to mingle.

What to Serve With Tuna Salad with Greek Yogurt

This salad goes well with crisp crackers for scooping or stuffed into a warm whole-wheat pita with lettuce and cucumber slices. For a low-carb option, serve it in romaine boats or endive leaves—they add a satisfying crunch. It also makes a great open-faced sandwich on sourdough with a thin smear of extra Dijon.

Frequently Asked Questions

Can I freeze tuna salad?

Freezing is not recommended. The yogurt and vegetables will release water and turn mushy when thawed.

Why is my tuna salad watery?

It usually means the tuna wasn’t drained well enough. Press the tuna firmly to remove all liquid before adding it to the bowl.

Can I use this recipe for a tuna melt?

Absolutely. Pile the salad onto a slice of bread, lay a piece of cheese on top, and broil until the cheese is bubbly and the edges are golden.

Is this recipe gluten-free?

The tuna salad itself is naturally gluten-free. Just serve it on gluten-free bread or in lettuce cups.
