The best part? You can make this easy tuna salad recipe with everyday ingredients, no fancy equipment and very little fuss. It’s a practical choice for meal prep, quick weekday lunches and those moments when you open the fridge and need inspiration fast.

Whether you’re collecting healthy lunch ideas, looking for easy high-protein meals or planning a delicious lunch that keeps you feeling satisfied, this recipe deserves a place in your regular rotation.

Why You’ll Love This High-Protein Tuna Spread

This recipe brings together three simple ingredients that work beautifully together.

Tuna provides a savoury, flaky base, hard-boiled eggs add richness, and cucumber delivers a cool, refreshing crunch. A little Greek yogurt and mayonnaise create a creamy dressing without making the mixture feel overly heavy.

Unlike a traditional tuna salad that can become soft and one-dimensional, this version balances creamy, crunchy and tangy textures. The cucumber gives every mouthful a fresh finish, while Dijon mustard, lemon juice and black pepper brighten the flavour.

It’s also wonderfully versatile. Make it for a quick lunch at home, pack it for work, prepare it for a picnic or serve it as a simple protein-rich snack.

And because the ingredients are easy to find, you don’t need an expensive shopping list to make something that feels fresh, colourful and satisfying.

Ingredients for Tuna Egg Cucumber Protein Spread

This recipe makes approximately 3 generous servings. The measurements give you a creamy, scoopable spread with enough cucumber for freshness without watering everything down.

What You’ll Need

• 2 cans tuna in spring water, drained (approximately 240 g drained weight)

• 3 large eggs

• ½ medium cucumber (approximately 100 g)

• 3 tablespoons plain Greek yogurt (45 g)

• 1 tablespoon mayonnaise (15 g)

• 1 teaspoon Dijon mustard (5 g)

• 1 tablespoon fresh lemon juice (15 ml)

• 2 tablespoons finely chopped red onion (20 g)

• 1 tablespoon chopped fresh parsley or dill

• ¼ teaspoon salt, or to taste

• ¼ teaspoon freshly ground black pepper

Optional extras: Add ¼ teaspoon garlic powder for a savoury kick, a pinch of chilli flakes for gentle heat or a little lemon zest for extra freshness.

For the best texture, choose tuna that flakes easily and a firm cucumber with crisp flesh. Greek yogurt adds a pleasant tang, while a small amount of mayonnaise gives the dressing a familiar, creamy finish.

How to Make Tuna Egg Cucumber Protein Spread

Step 1: Boil the Eggs

Place the eggs in a saucepan and cover them with cold water. Bring the water to a boil, then reduce the heat to maintain a gentle simmer.

Cook for 10–12 minutes, depending on the size of your eggs. Transfer them immediately to a bowl of ice-cold water and leave them for around 5 minutes before peeling.

Allowing the eggs to cool makes them easier to handle and helps keep the finished spread pleasantly chilled.

Step 2: Prepare the Tuna and Cucumber

Drain the tuna thoroughly, pressing out excess liquid with a fork. This small step makes a big difference because too much moisture can turn your creamy tuna salad into a watery mixture.

Finely dice the cucumber. If it has particularly watery seeds, scoop them out before chopping.

For extra-crunchy cucumber tuna salad, sprinkle the diced cucumber with a tiny pinch of salt, leave it for 5 minutes, then pat it dry with kitchen paper.

Finely chop the red onion and fresh herbs.

Step 3: Make the Creamy Dressing

In a medium mixing bowl, combine the Greek yogurt, mayonnaise, Dijon mustard and lemon juice.

Stir until smooth, then season with black pepper and salt to taste.

The dressing should taste bright, lightly tangy and savoury. If you prefer a creamier tuna egg salad, add another teaspoon of Greek yogurt. For a sharper finish, add a small squeeze of lemon.

Step 4: Combine Everything

Chop the cooled eggs into small chunks and add them to the bowl with the drained tuna.

Fold in the cucumber, red onion and fresh herbs. Add the dressing and gently mix until everything is coated.

Avoid stirring too vigorously. You want the tuna and eggs to remain slightly chunky rather than turning into a completely smooth paste.

Taste and adjust the seasoning. A little extra black pepper or fresh dill can make the flavours pop.

Step 5: Chill and Serve

You can enjoy the spread immediately, but chilling it for 10–15 minutes helps the flavours come together.

Spoon it onto wholegrain toast, fill a sandwich, serve it with crackers or add a generous scoop to a bowl of crunchy salad leaves.

For an easy high-protein lunch, pair it with wholegrain toast and cherry tomatoes. If you’re after a lighter option, cucumber rounds, lettuce cups or sliced bell peppers make excellent alternatives.

My Best Tips for a Perfect Tuna Egg Salad

1. Remove Excess Moisture

This is the secret to a thick, delicious tuna spread. Drain the tuna well and pat the cucumber dry if needed.

Too much liquid can dilute the dressing and leave your sandwich soggy.

2. Keep Some Texture

Don’t mash every ingredient into oblivion. Small chunks of egg, flaky tuna and crisp cucumber make the spread much more enjoyable.

A fork is all you need to achieve that lovely homemade texture.

3. Balance the Creaminess

Greek yogurt brings tang, while mayonnaise adds richness. Using both gives you a creamy tuna salad without relying entirely on mayonnaise.

You can adjust the ratio to suit your taste, but add extra dressing gradually to avoid making the mixture too loose.

4. Let the Flavours Develop

A short rest in the refrigerator gives the lemon, mustard and herbs time to mingle with the tuna and eggs.

Ten to fifteen minutes is enough to make a noticeable difference when you have time to spare.

5. Assemble Sandwiches Just Before Eating

For the freshest lunch, keep the tuna egg cucumber spread separate from your bread until you’re ready to eat.

This helps preserve the bread’s texture and keeps your sandwich from becoming soggy.

Delicious Ways to Serve This Easy Tuna Salad

One of my favourite things about this recipe is how easily it fits into different meals. You can serve the same batch in several ways without feeling like you’re eating the same lunch every day.

Tuna Egg Sandwich

Spread a thick layer between two slices of toasted wholegrain bread. Add lettuce, tomato and a little cracked black pepper for a classic tuna salad sandwich with extra freshness.

Crunchy Cucumber Boats

Slice a cucumber lengthwise, scoop out the centre and fill it with the tuna egg mixture. These little cucumber boats are colourful, crunchy and perfect when you want a lighter lunch or an easy appetiser.

High-Protein Lunch Bowl

Add a generous scoop to a bowl of mixed leaves, cherry tomatoes, grated carrots and sliced avocado. Serve with wholegrain crackers or a slice of toast for a more substantial meal.

Quick Tuna Crackers

Spoon the mixture onto seeded crackers just before serving. Finish with chopped dill or a little lemon zest for an easy snack that looks lovely on a lunch platter.

Lettuce Wraps

Use crisp romaine or butter lettuce leaves as little edible cups. Fill them with the tuna egg spread, add sliced radishes and enjoy a fresh, crunchy alternative to a sandwich.

Easy Variations to Try

Once you’ve made the basic recipe, it’s easy to customise it with ingredients you already have.

• Avocado tuna salad: Replace the mayonnaise with ¼ mashed avocado for a creamy twist.

• Spicy tuna spread: Add a pinch of chilli flakes or a dash of hot sauce.

• Mediterranean tuna salad: Stir in chopped olives, diced red pepper and a little extra lemon juice.

• Herby tuna egg salad: Use fresh dill, parsley or chives for a fragrant finish.

• No-mayo tuna salad: Replace the mayonnaise with an extra tablespoon of Greek yogurt, adjusting the seasoning to taste.

These simple variations give you plenty of healthy tuna salad ideas without needing to learn an entirely new recipe.

Storage and Meal Prep

Transfer leftover tuna egg cucumber protein spread to an airtight container and refrigerate promptly.

Because this recipe contains tuna, eggs and a dairy-based dressing, keep it refrigerated at 4°C or below and eat it within 3 days as a conservative meal-prep guideline. Always follow the storage instructions on your ingredients and discard the mixture if it has been left at room temperature for more than 2 hours.

For the best texture, store the mixture without adding any extra cucumber until serving if you’re preparing it ahead. You can also drain and chop the ingredients in advance, then combine everything shortly before lunch.

I don’t recommend freezing this spread. The cucumber can release water after thawing, while the eggs and creamy dressing may develop an unpleasant texture.

Frequently Asked Questions

Can I make tuna egg cucumber protein spread ahead of time?

Yes! You can prepare it a few hours ahead and refrigerate it in an airtight container. For the crunchiest results, prepare the cucumber separately and fold it in shortly before serving.

Can I use canned tuna in oil?

Absolutely. Drain it thoroughly before mixing. Tuna in oil usually creates a richer flavour, while tuna in spring water gives you a lighter-tasting result.

Is this a good high-protein lunch?

It can be an excellent protein-rich lunch option. Tuna and eggs provide most of the protein, while Greek yogurt contributes a little more. Your overall meal will depend on portion size and what you serve alongside it.

How can I make the spread less creamy?

Reduce the mayonnaise to 1 teaspoon and use just enough Greek yogurt to bind the ingredients. Keep the tuna chunky and add cucumber gradually until you achieve your preferred texture.

What can I use instead of cucumber?

Finely diced celery, red bell pepper or spring onions can add crunch. The flavour will be slightly different, but the spread will still make a tasty filling for sandwiches, wraps and crackers.
