Ingredients
- Canned tuna: 4 cans (5 oz each), drained well; use tuna in water for lighter calories or in olive oil for richer flavor
- Greek yogurt: 1/2 cup (for creaminess with extra protein)
- Mayonnaise: 3–4 tablespoons (adjust to taste)
- Dijon mustard: 2 teaspoons
- Lemon juice: 2 tablespoons, plus more to taste
- Celery: 2 ribs, finely chopped
- Red onion: 1/4 cup, finely chopped (or use green onion for a milder bite)
- Fresh herbs: 2 tablespoons chopped dill or parsley
- Pickles or capers: 2 tablespoons, chopped (optional for briny bite)
- Salt and black pepper: to taste
- Olive oil: 1 tablespoon (optional, boosts richness)
- Veggie sides: cherry tomatoes, cucumber slices, carrot sticks, bell pepper strips
- Carb options: whole-grain crackers, pita, or cooked quinoa/brown rice
- Healthy fats: avocado slices or a small container of olives (optional)
- Greens: baby spinach or mixed greens for layering (optional)
- Lemon wedges: for serving (optional)
How to Make It
- Drain the tuna well. Press gently with the lid to squeeze out excess liquid.
Too much moisture will make the salad watery.
- Make the dressing. In a large bowl, whisk Greek yogurt, mayo, Dijon, lemon juice, olive oil (if using), salt, and pepper. Taste and adjust lemon or salt as needed.
- Add the mix-ins. Stir in celery, red onion, herbs, and pickles or capers. Fold in the tuna with a fork, breaking up big chunks while keeping some texture.
- Prep the sides. Wash and chop your veggies.
If you’re using grains, cook them ahead and let them cool completely.
- Assemble the boxes. Divide the tuna salad into 4–5 meal prep containers. Add a handful of veggies, a portion of grains or crackers (pack dry items separately if needed), and optional avocado or olives.
- Finish with freshness. Add lemon wedges or pack a small container of extra dressing if you like things zestier.
- Chill. Seal and refrigerate. The flavors meld nicely after an hour, making them even better the next day.
How to Store
- Refrigerator: Keep sealed for up to 4 days.
Store crackers, pita, or chips separately so they don’t soften.
- Greens and avocado: Layer greens under the tuna or pack separately. Add avocado the day you eat to prevent browning.
- No freezing: Tuna salad with yogurt or mayo doesn’t freeze well and can separate when thawed.
- Meal prep tip: If you prefer maximum crunch, mix the tuna salad base and stir in celery and onion the day of eating.
Health Benefits
- High-quality protein: Tuna delivers complete protein to keep you full and support muscle health.
- Omega-3 fats: Tuna contains EPA and DHA, which support heart and brain health.
- Lighter dressing: Using Greek yogurt cuts calories and adds calcium and extra protein.
- Veggie fiber: Crunchy vegetables boost fiber for digestion and satiety.
- Balanced macros: Combine tuna, healthy fats, and smart carbs for steady energy through the afternoon.
Common Mistakes to Avoid
- Not draining tuna enough: Excess liquid waters down the dressing and dulls flavor.
- Overmixing: Mashing the tuna too much leads to a paste-like texture. Keep some flakes for bite.
- Skipping acid: Lemon or a splash of vinegar brightens and balances the creamy dressing.
- Packing wet and dry together: Keep crackers or pita separate to stay crisp.
- Overloading onion: Raw onion can overpower the salad over time.
Start small and adjust.
- Ignoring salt: Tuna needs seasoning. Taste and tweak before packing.
Variations You Can Try
- Mediterranean: Add chopped cucumber, cherry tomatoes, kalamata olives, and feta. Use parsley and an extra splash of olive oil.
- Spicy Sriracha: Mix sriracha into the dressing and fold in sliced green onions and cilantro.
Serve with edamame and rice.
- Avocado Lime: Swap some yogurt for mashed avocado, add lime juice and cumin. Pair with corn, black beans, and bell pepper.
- Curried: Stir in mild curry powder, golden raisins, and diced apples. Serve with spinach and whole-grain pita.
- No-Dairy: Use all mayo or a dairy-free yogurt.
Add extra lemon and herbs to keep it bright.
- Tuna Nicoise-Inspired: Include blanched green beans, baby potatoes, olives, and a jammy egg. Keep the dressing tangy with Dijon and lemon.
FAQ
Can I use tuna in oil instead of water?
Yes. Tuna in oil is richer and more flavorful.
Just drain it well and reduce the added olive oil or mayo so the salad doesn’t get heavy.
How long does tuna salad stay fresh?
Up to 4 days in the fridge when stored in a sealed container. If you’re sensitive to onion getting strong, add it fresh on the day you eat.
What can I use instead of Greek yogurt?
Use all mayo for classic flavor, or try dairy-free yogurt or mashed avocado for a creamy alternative. Adjust lemon and salt to balance.
Is there a lower-sodium option?
Rinse canned tuna briefly and pat dry, choose low-sodium mustard and pickles, and season with lemon and herbs instead of extra salt.
Can I make this with fresh tuna?
You can use cooked, flaked fresh tuna.
Sear or poach until just cooked, cool completely, then proceed with the recipe. The flavor is milder and very clean.
What’s the best container for meal prep?
Use a divided bento-style container or pack the tuna in one small container and sides in another. This keeps textures separate and crisp.
How do I keep the tuna from smelling in the office?
Pack it cold in a tight, leakproof container and eat it chilled.
Adding lemon and fresh herbs helps keep the aroma clean and mild.
Can I add eggs?
Absolutely. Chopped hard-boiled eggs add richness and more protein. Reduce the mayo slightly to keep the texture balanced.
What carbs pair best?
Whole-grain crackers, pita, quinoa, brown rice, or a small portion of pasta salad all work well.
Choose one to round out your macros.
How can I make it kid-friendly?
Go lighter on onion and pickles, add sweet corn or diced apples, and serve with crackers or mini pitas for scooping. Keep the seasoning mild.
