Spicy Tuna Salad

A fresh, crunchy, and creamy spicy tuna salad loaded with crisp vegetables and a fiery dressing that beats any takeout joint.

Why This Recipe Works:

• Maximum Emulsion: Squeezing the tuna dry prevents the dressing from breaking and getting watery.
• Kewpie Richness: Using Japanese mayonnaise provides an ultra-rich, savory base thanks to egg yolks and natural MSG.
• Structural Crunch: Sliced radishes and Persian cucumbers add a refreshing bite that holds up beautifully over time.

The first time I had a truly life-changing spicy tuna bowl was in a cramped, neon-lit basement diner near Shibuya Station. The chef aggressively whipped the dressing with a tiny bamboo whisk.

My hands were literally cramping from holding oversized chopsticks, but I could not stop shoveling the cold, fiery fish into my mouth.

Back home, my early attempts to recreate it were absolute disasters because I ended up with a soggy, metallic-tasting mush.

Here is the science behind why your homemade tuna salad often turns into a watery, sad mess. Canned tuna is packed with water or oil that clings to the protein matrix of the fish. If you do not aggressively press that moisture out, it will slowly leak into your dressing, breaking the emulsion and leaving you with a soggy puddle.

It is incredibly frustrating.

The fix is simple but non-negotiable. Grab a fine-mesh strainer and press the tuna with a heavy spoon until your forearms ache and the fish is bone-dry. This allows the creamy dressing to cling to every single flake of fish.

Then, we toss in crisp cucumbers and radishes. They provide a crucial, refreshing crunch that offsets the rich mayo, much like the texture profile in my favorite Sushi Cucumber Salad.

Trust me, this technique changes everything.

Ingredients

• 2 cans (5 oz each) albacore tuna in water, drained
• 1/3 cup Kewpie mayonnaise
• 1 tbsp sriracha (adjust to taste)
• 1 tsp toasted sesame oil
• 1/2 cup Persian cucumbers, finely diced
• 1/4 cup red radishes, finely diced
• 2 green onions, thinly sliced
• 1/2 tsp Diamond Crystal kosher salt
• 1/2 tsp toasted black sesame seeds (for garnish)

Directions

1. Drain the canned tuna thoroughly. Place it in a fine-mesh strainer and press firmly with a spoon to extract as much liquid as possible.
2. In a medium bowl, whisk together the Kewpie mayonnaise, sriracha, toasted sesame oil, and Diamond Crystal kosher salt until smooth and emulsified.
3. Flake the dried tuna into the bowl with the dressing. Use a fork to mix until the tuna is fully coated.
4. Gently fold in the diced Persian cucumbers, radishes, and sliced green onions.
5. Divide into bowls and garnish with toasted black sesame seeds before serving.

Notes

• Salt Conversion: I highly recommend using Diamond Crystal kosher salt. If you are using fine table salt or Morton's, cut the volume in half to 1/4 teaspoon to avoid over-salting.
• The Kewpie Difference: Kewpie mayonnaise is essential here because it is made exclusively with egg yolks rather than whole eggs, creating a tighter emulsion and a richer, more savory flavor profile due to natural MSG.
• Texture Warning: Do not overwork the tuna when mixing it with the dressing. Over-mashing will break down the fish fibers into a baby-food-like paste instead of keeping those desirable, flaky pockets of texture.
• Storage Behavior: After 24 hours in the fridge, the vegetables will naturally release some water. Give it a quick, vigorous stir with a fork to re-emulsify the dressing before eating.

Serving Suggestions

This versatile salad can be enjoyed in several delicious ways. Here are my favorite ways to plate and serve it for a quick meal:

• Serve it over a bed of warm jasmine rice for an easy, deconstructed sushi bowl.
• Scoop it up with crispy seaweed snacks (nori sheets) for a low-carb crunch.
• Stuff it into a halved avocado to make a rich, satisfying lunch.
• Pair it with a side of California Roll Cucumber Salad for a double dose of fresh greens.

Storage and Reheating

This salad is best enjoyed fresh, but it will keep in an airtight container in the fridge for up to two days. Do not freeze it under any circumstances. The mayonnaise emulsion will completely break upon thawing.

It gets watery if left longer.

For meal prep, store the chopped vegetables and the tuna mixture in separate containers. Combine them right before serving to maintain crunch.

Ingredient Substitutes

If you need to swap out some ingredients, these alternatives work beautifully without sacrificing flavor:

1. Kewpie Mayonnaise: Use regular mayonnaise mixed with a pinch of sugar and a drop of rice vinegar.
2. Persian Cucumbers: English cucumbers work perfectly; just scoop out the watery seeds first.
3. Sriracha: Substitute with chili garlic sauce or sambal oelek for a different kind of heat.
4. Radishes: Jicama or water chestnuts can provide a similar crisp, refreshing bite.
