Recipe at a Glance

Ingredients

For the Tuna Salad

• 2 cans tuna in water, approximately 5 oz (142 g) each, drained
• ½ cup plain Greek yogurt
• 1 tablespoon mayonnaise, optional
• ¼ cup finely diced celery
• ¼ cup finely diced cucumber
• 2 tablespoons finely diced red onion
• 2 tablespoons chopped dill pickles
• 1 tablespoon fresh parsley, chopped
• 1 teaspoon Dijon mustard
• 1 teaspoon fresh lemon juice
• ½ teaspoon garlic powder
• ¼ teaspoon black pepper
• ¼ teaspoon salt, or to taste

Optional Additions

• 1 hard-boiled egg, chopped
• 1 tablespoon chopped green onion
• 1 teaspoon capers
• ¼ avocado, diced
• 1 tablespoon sunflower seeds
• 1 tablespoon chopped walnuts
• Fresh dill
• Pinch of paprika
• Pinch of red pepper flakes

Step-by-Step Instructions

1. Drain the Tuna

Open the tuna cans and drain them thoroughly.

For the best texture, press out as much excess water as possible.

Transfer the tuna to a large mixing bowl.

Use a fork to break it into smaller pieces.

Do not mash it into a paste; leaving some small chunks gives the salad a better texture.

2. Prepare the Vegetables

Finely dice:

• Celery
• Cucumber
• Red onion
• Pickles

Chop the parsley.

Smaller pieces distribute throughout the tuna much better and make every bite flavorful.

3. Make the Creamy Dressing

In a separate small bowl, combine:

• Greek yogurt
• Mayonnaise
• Dijon mustard
• Lemon juice
• Garlic powder
• Black pepper

Mix until smooth.

Taste the dressing before adding it to the tuna.

Add a little more lemon juice or mustard if you prefer a tangier flavor.

4. Combine Everything

Add the celery, cucumber, onion, pickles, and parsley to the tuna.

Pour the dressing over everything.

Gently fold together with a spoon or spatula.

Don’t overmix.

5. Adjust the Seasoning

Taste the tuna salad.

Add salt if necessary.

For more flavor, add:

• Extra black pepper
• Fresh dill
• A little Dijon mustard
• Lemon juice
• Paprika

6. Chill

For the best flavor, cover and refrigerate for approximately 20–30 minutes.

This gives the ingredients time to blend together.

You can also eat it immediately.

What Makes This Tuna Salad High in Protein?

The main protein sources are:

Tuna

Tuna provides a concentrated source of protein.

Greek Yogurt

Greek yogurt increases protein while creating the creamy texture without requiring a large amount of mayonnaise.

Optional Egg

A chopped hard-boiled egg adds additional protein and makes the salad even more filling.

How to Make It Even Higher in Protein

For a very high-protein version, use:

• 2 cans tuna
• ¾ cup nonfat Greek yogurt
• 1 hard-boiled egg
• Vegetables and seasonings

You can also add a small amount of cottage cheese that has been blended until smooth.

The exact protein content depends on the brands and quantities used.

Healthier Creamy Dressing

For a lighter version, skip the mayonnaise completely.

Use:

• ¾ cup Greek yogurt
• 1 teaspoon Dijon mustard
• 1 teaspoon lemon juice
• Garlic powder
• Black pepper
• Fresh dill

This creates a creamy dressing with more protein and less fat.

Mediterranean Tuna Salad

For a Mediterranean-inspired version, add:

• Chopped cucumber
• Cherry tomatoes
• Kalamata olives
• Red onion
• Fresh parsley
• Feta cheese
• Lemon juice

Replace the mayonnaise with extra Greek yogurt and a small drizzle of extra-virgin olive oil.

Spicy Tuna Salad

Add:

• ½ teaspoon hot sauce
• ¼ teaspoon red pepper flakes
• ½ teaspoon smoked paprika
• Finely diced jalapeño

For extra creaminess, mix in a little Greek yogurt.

Avocado Tuna Salad

Replace the mayonnaise with:

• ½ ripe avocado

Mash the avocado and combine it with the tuna and Greek yogurt.

Add extra lemon juice to help balance the richness.

Crunchy Tuna Salad

For extra crunch, add:

• Celery
• Cucumber
• Bell pepper
• Pickles
• Sunflower seeds

Chopped apples can also provide a pleasant sweet-and-crunchy contrast.

No-Mayonnaise Tuna Salad

For a completely mayo-free version, use:

• ¾ cup Greek yogurt
• 1 teaspoon Dijon mustard
• 1 teaspoon lemon juice
• Fresh dill
• Garlic powder
• Black pepper

The Greek yogurt provides plenty of creaminess.

Low-Carb Version

For a lower-carb meal:

• Serve over leafy greens.
• Use cucumber and celery.
• Avoid bread and crackers.
• Skip sweetened sauces.
• Use Greek yogurt instead of mayonnaise.
• Add avocado for healthy fats.

No-Sugar Version

The basic recipe contains no added sugar.

For a strict no-added-sugar version:

• Choose plain Greek yogurt.
• Use unsweetened tuna.
• Check pickle labels for added sugar.
• Use mustard without added sugar.
• Avoid sweet relish.

Meal Prep Instructions

This recipe is excellent for meal prep.

Prepare the tuna salad and place it into airtight containers.

Keep bread, crackers, lettuce, and other toppings separate so they don’t become soggy.

For best quality, refrigerate promptly and use within 3–4 days.

If the salad has been sitting at room temperature for an extended period, discard it rather than attempting to refrigerate and reuse it.

Storage

Store the tuna salad in an airtight container in the refrigerator.

Keep the refrigerator at 40°F (4°C) or below.

Don’t leave the salad at room temperature for more than about 2 hours; if the surrounding temperature is very hot, food should not remain out for more than about 1 hour.

Freezing

Freezing is not recommended.

Greek yogurt, mayonnaise, and fresh vegetables can separate and become watery after thawing.

For the best texture, prepare it fresh or refrigerate it for a few days.

Troubleshooting Guide

Pro Tips for Perfect Tuna Salad

Tip 1: Drain the tuna extremely well

Excess liquid is one of the main causes of watery tuna salad.

Tip 2: Don’t overdo the mayonnaise

Greek yogurt provides plenty of creaminess while keeping the recipe protein-focused.

Tip 3: Add lemon gradually

A little lemon brightens the entire recipe.

Tip 4: Use fresh herbs

Fresh dill or parsley can dramatically improve the flavor.

Tip 5: Let it rest

Even 20 minutes in the refrigerator allows the flavors to develop.

Tip 6: Keep toppings separate

If meal prepping, keep lettuce, bread, crackers, and crunchy vegetables separate.

Tip 7: Taste before adding salt

Tuna, pickles, mustard, and mayonnaise can already contain significant salt.

Best Serving Combination
