Quick Tip

All ingredient amounts are listed in the recipe card below

Canned tuna (120 grams): I prefer tuna packed in water for a lighter flavor and easy mixing with the yogurt and avocado.
Avocado (½ medium): Adds rich creaminess and healthy fats that make the salad incredibly satisfying.
Plain Greek yogurt (¼ cup): The star replacement for mayo, bringing tang, protein, and a silky texture.
English cucumber (½ cup, diced): Offers refreshing crunch and moisture, balancing the creamy ingredients.
Green olives (¼ cup, chopped): Impart subtle salty, briny notes that elevate the overall flavor.
Fresh dill (¼ cup, chopped): Delivers a fragrant, herbaceous lift that brightens the dish.
Fresh lemon juice (from ½ lemon): Adds essential zing and lightness.
Garlic powder (1 tsp): Infuses a gentle depth without overpowering the other ingredients.
Salt + pepper (to taste): Enhances and balances all the flavors perfectly.

Directions

Step 1: Start by dicing the English cucumber, chopping the green olives, and finely chopping the fresh dill. Set these aside for when you mix the salad.

Step 2: In a large bowl, mash the half avocado until smooth but still a little chunky—that texture makes the salad delightfully creamy and interesting.

Step 3: Add the canned tuna (make sure it’s drained well), Greek yogurt, diced cucumber, chopped olives, and chopped dill into the bowl with the avocado.

Step 4: Squeeze the fresh lemon juice over the mixture, then sprinkle in the garlic powder, salt, and pepper to your liking. I always start with a little and adjust as I mix.

Step 5: Gently fold everything together until well combined but avoid overmixing—you want to keep some of the texture from the olives and cucumber for that satisfying bite.

Step 6: Taste and adjust the seasoning if necessary, then it’s ready to serve! I love scooping this tuna salad into crisp lettuce leaves or spreading it onto crunchy whole-grain toast for an easy meal.

When I serve this salad, I love how versatile it is. One of my favorite ways is as a scoop inside crisp butter lettuce cups, which adds a fresh crunch and keeps the meal light. If I’m feeling like something more substantial, I spread it thickly over toasted multigrain bread or place it on top of a bed of mixed greens for a quick protein boost that feels wholesome and satisfying.

For garnishing, I often sprinkle a little extra fresh dill on top along with a light drizzle of lemon juice to brighten the presentation. Adding a few thin cucumber slices or a couple of green olive halves for visual appeal also makes a lovely finishing touch. This salad is best served chilled or at room temperature, which really lets the flavors shine through without any heaviness.

It’s a fantastic dish for casual occasions like quick weeknight dinners, healthy office lunches, or a refreshing addition to a summer picnic spread. Pair it with a side of crunchy celery sticks, cherry tomatoes, or a simple quinoa salad to round out the meal. For drinks, I like to keep things light—cold sparkling water with a twist of lemon or an iced herbal tea complements the fresh flavors beautifully.

Variations

I enjoy experimenting with this recipe to suit different tastes and dietary needs. For example, if you want to boost the veggie content even more, try adding finely chopped bell peppers or shredded carrots for extra crunch and color. I’ve also swapped the green olives for capers when I wanted a sharper, tangier note—that’s a great way to change things up without losing the salad’s character.

For those who are dairy-free or vegan, I recommend substituting the Greek yogurt with a plant-based yogurt alternative like coconut or almond yogurt. You can also replace the canned tuna with chickpeas or mashed white beans to keep it high in protein but completely plant-based. Experimenting with fresh herbs like parsley or cilantro instead of dill gives the salad a different herbal twist I find really refreshing.

If you want to add a little heat, a pinch of smoked paprika or a dash of chili flakes works wonders without overpowering the delicate flavors. This salad is designed to be no-cook and quick, but I’ve also tried gently warming it with sautéed veggies on the side for a cozy variation that still feels fresh and vibrant.

Storage and Reheating

Storing Leftovers

If you have any leftovers, I recommend storing the tuna salad in an airtight container in the refrigerator. Make sure it’s tightly sealed to keep it fresh and to prevent it from absorbing other fridge odors. It will keep well for up to 2 days, though I find it tastes best the same day since the avocado can start to brown and the yogurt texture may change after a couple of days.

Freezing

Because of the avocado and Greek yogurt, this salad isn’t ideal for freezing. These ingredients tend to separate and lose their bright texture when thawed, resulting in a less appealing consistency. I usually suggest making only as much as you plan to eat within a couple of days to enjoy it at its best.

Reheating

This salad is best enjoyed cold or at room temperature, so I don’t recommend reheating. If you want a warm meal, I suggest serving the tuna salad alongside warm sides rather than heating it directly. Keeping it chilled preserves the fresh, creamy texture and vibrant flavors that make this salad so enjoyable.

FAQs

Can I use tuna packed in oil instead of water?

Absolutely! Tuna packed in oil will add a richer flavor and a bit more fat to the salad. You might want to reduce the amount of avocado slightly to keep the creaminess balanced. Just be sure to drain the tuna well to avoid making the salad too oily.

Is this recipe suitable for meal prepping?

This recipe is great for meal prepping, but I recommend preparing it fresh or within a day or two. The avocado can brown and the texture of the yogurt may change over time. To keep things fresh longer, you can store the avocado mashed separately with a bit of lemon juice and mix just before serving.

Can I add other vegetables or ingredients for extra flavor?

Definitely! I love tossing in diced bell peppers, cherry tomatoes, or even some finely chopped celery for extra crunch and color. You can also add herbs like parsley or chives to vary the flavor. Just keep the balance of textures in mind so the salad stays lively.

What can I use if I don’t have Greek yogurt?

If Greek yogurt isn’t available, you can substitute with plain yogurt, strained yogurt, or a plant-based yogurt alternative. Straining regular yogurt through a cheesecloth to remove excess whey helps achieve a thicker consistency similar to Greek yogurt, which is ideal for this salad.

Is this recipe gluten-free?

Yes! All the ingredients in this recipe are naturally gluten-free. Just be cautious if you pair the salad with bread or crackers—choose gluten-free options to keep it safe for gluten-sensitive individuals.
