Spicy Tuna Salad

A vibrant, creamy, and crunchy spicy tuna salad loaded with crisp greens, quick-pickled onions, and a fiery sesame-mayo dressing that actually stays emulsified.

Why This Recipe Works:

• Osmotic Control: Salting and draining the cucumbers beforehand prevents them from weeping water into the dressing.
• Yolk-Rich Emulsion: Kewpie mayonnaise uses only egg yolks, creating a stronger, creamier protein matrix than standard mayo.
• Toasted Aromatics: Incorporating pure toasted sesame oil blooms the green onions, unlocking fat-soluble flavor compounds.

The first time I tasted this was in Kyoto.

I was hooked.

A retired chef served it over warm, seasoned rice in a tiny, humid basement kitchen that smelled of toasted sesame.

I watched him whip the dressing with a tiny bamboo whisk.

But back home, my early attempts turned into a watery puddle, which got annoying fast. Bear with me here, because the physics of this is simple.

Salt pulls water straight out of vegetable cell walls.

It ruins everything.

When osmotic pressure dilutes your beautiful emulsion, you are left with a soggy, separated mess at the bottom of the bowl.

This brand of failure is entirely preventable.

The simple fix is hands down the easiest trick.

Just salt first.

By drawing out the moisture from the cucumbers beforehand, we protect the integrity of our creamy, egg-yolk-rich Kewpie mayonnaise dressing which relies on oil-soluble flavor compounds to bind beautifully.

This builds a robust protein matrix that clings to every leaf, ensuring your salad stays perfectly emulsified for hours.

Ingredients

• 2 cans (5 oz each) solid white albacore tuna in olive oil, drained
• 1 cup English cucumber, thinly sliced
• 1/2 tsp Diamond Crystal kosher salt
• 3 cups mixed baby greens
• 2 green onions, thinly sliced
• 3 tbsp Kewpie mayonnaise
• 1 tbsp sriracha
• 1 tsp toasted sesame oil
• 1 tsp soy sauce
• 1 tbsp toasted sesame seeds

Directions

1. Toss the sliced cucumbers with the Diamond Crystal kosher salt in a colander and let them drain for 10 minutes. Squeeze them gently with your hands to remove excess moisture.
2. In a medium bowl, whisk together the Kewpie mayonnaise, sriracha, toasted sesame oil, and soy sauce until smooth and fully emulsified.
3. Flake the drained tuna into the dressing bowl, using a fork to gently break up the larger chunks without turning it into mush.
4. Add the drained cucumbers and sliced green onions to the bowl, folding them gently into the tuna mixture.
5. Arrange the crisp greens in a modern serving bowl, scoop the spicy tuna mixture over the top, and garnish generously with toasted sesame seeds.

Notes

• Mayo Swap: Use Kewpie mayonnaise for the ultimate creamy texture; if substituting regular mayonnaise like Hellmann's, add 1/4 teaspoon of sugar and a splash of rice vinegar to mimic Kewpie's distinct flavor profile.
• Tuna Selection: Tuna packed in oil is highly recommended over water-packed tuna because the oil-soluble flavor compounds in the fish are preserved, resulting in a richer, less metallic taste.
• Toasting Warning: When toasting your sesame seeds, keep the pan moving constantly over medium-low heat; they transition from perfectly golden to bitter and burnt in a matter of seconds.
• Storage Behavior: After a day in the fridge, the greens will inevitably wilt, but the spicy tuna mixture itself holds up beautifully and actually tastes better as the flavors meld.
• Salt Conversion: We use Diamond Crystal kosher salt here; if you are using Morton's kosher salt or fine table salt, cut the volume in half to avoid over-salting.

Serving Suggestions

This vibrant salad is incredibly versatile and can be enjoyed as a light lunch or transformed into a hearty dinner.

• Scoop it onto toasted slices of rustic sourdough bread for an open-faced sandwich.
• Serve it alongside a refreshing cucumber salad to double down on the crunch.
• Add it to a gorgeous tinned fish board for your next casual gathering.
• Wrap it in large butter lettuce leaves for low-carb, hand-held wraps.

Storage and Reheating

Eat this fresh if you can.

If you do have leftovers, store the spicy tuna mixture and the crisp greens in separate airtight containers. Mixing them beforehand is a one-way ticket to soggy town, and nobody wants that.

The tuna mixture keeps in the fridge for three days. Just stir before serving.

Do not freeze this.

Mayonnaise-based dressings do not survive the freezing and thawing process. The emulsion will break completely, leaving you with a separated, oily mess.

Ingredient Substitutes

If you don't have everything in your pantry, don't panic. Here are some easy swaps that work beautifully:

1. Tuna: Swap the canned tuna for canned salmon or even shredded chicken breast if you prefer.
2. Kewpie Mayo: Use Greek yogurt mixed with a touch of olive oil for a lighter, high-protein alternative.
3. Sriracha: Use chili garlic sauce or gochujang paste for a deeper, fermented spicy kick.
4. English Cucumber: Persian cucumbers work perfectly without needing to be peeled.
