Using 300 grams excellent quality tuna cut into thick cubes, the recipe balances the rich, buttery bite of tuna and avocado with crisp cucumber, toasted sesame seeds, and a lively togarashi-spiced dressing. It’s simple enough to pull together in under 20 minutes, but feels and tastes elegant enough for company.

Why this Tuna tartare with togarashi dressing works

The success of any raw fish dish comes down to three things: quality, contrast, and seasoning. This recipe uses 300 grams excellent quality tuna cut into thick cubes to preserve a meaty chew and showcase the fish. Creamy avocado and crunchy Mediterranean cucumber (or a 10 cm English cucumber, skin on, small dice) add texture contrast, and the togarashi-inspired dressing—blending sesame oil, peanut oil, soy, honey, ginger, garlic, and chillies—adds heat, umami, and a touch of sweetness. A scatter of black and white toasted sesame seeds finishes it with a nutty crunch and visual flair.

Ingredients

• 300 grams excellent quality tuna cut into thick cubes
• ½ an avocado diced
• ½ Mediterranean cucumber or 10 cm English cucumber, skin on, small dice
• Black and white toasted sesame seeds for garnish
• A few slices of radish (optional)
• Lime wedges to serve
• 1 tsp finely grated ginger
• 1 clove garlic minced
• ½–1 red chilli deseeded and finely chopped (adjust to heat preference)
• 2 tsp (10 ml) sesame oil
• 1 Tbsp (15 ml) peanut oil
• 1 tsp honey
• 2–3 tsp soy sauce
• ¼–½ tsp chilli powder or togarashi spice blend to taste

Tools and prep notes

• A sharp chef’s knife and a small paring knife for neat cubes
• Two small mixing bowls — one for dressing and one for tossing
• Measuring spoons and a teaspoon for the oils and soy
• A small spoon to drizzle dressing and a fork for tasting
• Toast sesame seeds lightly in a dry pan if they aren’t pre-toasted

Flavor tips

• Use tuna that is labeled for raw consumption and comes from a trusted fishmonger; its texture makes all the difference.
• If you prefer a milder heat, start with ½ teaspoon of the chilli powder or togarashi and ½ of the red chilli, then taste and add more.
• Peanut oil adds a subtle richness; if you need an alternative due to allergies, use a neutral oil like grapeseed oil and increase sesame oil by ½ tsp for aroma.
• Gently toss the ingredients—over-handling the tuna will break up the cubes and change the texture.

Rewritten step-by-step directions

1. Prepare the tuna: Pat 300 grams excellent quality tuna dry with paper towel. Cut the tuna into thick, even cubes and place them in a medium mixing bowl. Keep the cubes intact so they hold their shape when tossed with the dressing.
2. Dice the produce: Dice ½ an avocado and set aside in a small bowl. Dice ½ Mediterranean cucumber or a 10 cm English cucumber (skin on) into small, even pieces. If using radish, slice a few thinly and set them aside as a garnish.
3. Make the dressing: In a small bowl, combine 1 tsp finely grated ginger, 1 clove garlic minced, ½–1 red chilli deseeded and finely chopped, 2 tsp (10 ml) sesame oil, 1 Tbsp (15 ml) peanut oil, 1 tsp honey, and 2–3 tsp soy sauce. Whisk these together until the honey is dissolved and the oils and soy are combined. Taste and adjust the soy sauce for saltiness and the chilli for heat.
4. Add spice: Stir ¼–½ tsp chilli powder or togarashi spice blend into the dressing to infuse it with smoky heat. Start with ¼ tsp and increase to ½ tsp if you want a bolder spice presence. Mix until evenly distributed.
5. Toss tuna with dressing: Pour most of the dressing over the cubed tuna in the mixing bowl, reserving a small amount to finish the plate. Gently fold the dressing into the tuna using a rubber spatula or two forks so the cubes remain intact. Work quickly to coat the fish evenly without over-mixing.
6. Combine with avocado and cucumber: Add the diced avocado and diced cucumber to the dressed tuna. Using gentle folds, combine the ingredients until the avocado and cucumber are evenly distributed among the tuna. Take care not to mash the avocado—the goal is distinct cubes and bright texture contrast.
7. Plate the tartare: Arrange the mixture on a chilled plate or in a ring mold for a tidy presentation. If you used a ring mold, gently lift it straight up to keep the shape. Spoon the reserved dressing around or over the top for extra shine and flavor.
8. Garnish: Sprinkle black and white toasted sesame seeds generously over the top for nutty crunch. Add a few radish slices if using, tucking them around the tartare for color and a peppery bite. Place lime wedges on the side to squeeze over just before eating.
9. Serve immediately: Tuna tartare with togarashi dressing is best enjoyed right away while the tuna is cool and the textures are fresh. Offer extra soy or lime on the side for guests who want to boost salt or acidity.

Serving suggestions

Present this Tuna tartare with togarashi dressing simply so the flavors sing. Serve it atop thinly sliced cucumber rounds, on crisp toasted rounds, or with neutral crackers. It also pairs beautifully with steamed rice or on top of small rice cakes for a slightly fuller bite. A chilled glass of crisp white wine, a citrusy mocktail, or green tea are excellent companions.

Make-ahead and storage

Because this dish is best fresh, do not dress the tuna more than 10–15 minutes before serving. You can prepare the dressing, dice the avocado and cucumber, and cube the tuna up to 30 minutes ahead, keeping each component chilled and covered. Once combined, serve immediately; leftovers will become watery and lose texture, and should be eaten within 12 hours if refrigerated tightly.

Variations and swaps

• Vegetable-forward: Add finely diced mango for a sweet contrast or thinly sliced scallions for a sharper onion note.
• Nut-free variation: Replace peanut oil with grapeseed oil and increase sesame oil by ½ tsp for flavor.
• Less heat: Use ½ of the red chilli and ¼ tsp spice to keep things mild and approachable for those sensitive to heat.

Notes on presentation

Small details elevate this Tuna tartare with togarashi dressing: chill your serving plates ahead of time, use a ring mold for a clean cylinder, and scatter seeds and radish for contrast. Finish with a squeeze of lime over the top just before eating—the acidity brightens the fish and ties the dressing together.
