Japanese Marinated Tuna Rice Bowl (Maguro Zuke Don)

A traditional Japanese rice bowl featuring succulent soy marinated raw tuna arranged over fluffy rice with fragrant shiso ginger and sesame seeds.

Ingredients

• 300 g Southern bluefin tuna block
• 3 tbsp soy sauce
• 3 tbsp mirin
• 1 small handful bonito flakes
• 2 servings cooked sushi rice or white rice
• 1 sheet nori seaweed
• 2 leaves shiso leaves, shredded
• 1 tbsp pickled ginger, slivered
• 1 tsp white sesame seeds
• 1 tsp wasabi, optional

Instructions

1. 1Slice the tuna

   

   Using a sharp sushi knife, carefully slice the block of raw Southern bluefin tuna into uniform pieces suitable for the donburi bowl.

   Tip: Keep the knife blade wet and use a single long, smooth motion to ensure clean cuts without tearing the delicate fish flesh.
2. 2Marinate the tuna

   

   Gently place the sliced raw tuna into the cooled soy-mirin marinade, ensuring each slice is fully submerged for even flavor absorption.

   Tip: Do not overcrowd the bowl; ensure there is enough room for the marinade to coat every surface of the fish slices.
3. 3Let the tuna marinate

   

   Allow the tuna slices to soak in the dark marinade for approximately 5 to 10 minutes, letting the fish absorb the savory flavors.

   Tip: Five to ten minutes is sufficient to infuse flavor without altering the delicate texture of the raw tuna.
4. 4Prepare the marinade

   

   Combine mirin and soy sauce in a 1:1 ratio in a small pot. Bring the mixture to a boil to evaporate the alcohol in the mirin, remove from heat, stir in the bonito flakes to infuse umami, then let the sauce cool completely before using.

   Tip: Boiling the mixture is essential to remove the sharp taste of raw alcohol from the mirin.
5. 5Prepare the rice base

   

   Place a serving of freshly cooked white rice into a black bowl, gently pressing it down to create an even, compact bed for the toppings.

   Tip: You can use either plain steamed white rice or lightly seasoned sushi rice as the base for this dish.
6. 6Garnish with seaweed

   

   Using chopsticks, take a portion of shredded dried seaweed (nori) and sprinkle it evenly over the bed of white rice.

   Tip: Distributing the seaweed thinly across the rice adds a nice depth of flavor and texture to each bite.
7. 7Assemble the tuna slices

   

   Place the marinated tuna slices over the rice and seaweed, arranging them in an overlapping circular pattern to create a beautiful and even layer.

   Tip: Handle the tuna slices gently so they remain intact and maintain their polished appearance.
8. 8Add fresh garnish

   

   Spoon the freshly chopped ginger and shredded green shiso leaves directly into the center of the tuna arrangement to provide a sharp, aromatic contrast.

   Tip: Use a generous amount of ginger and shiso to balance the rich umami flavor of the tuna.
9. 9Garnish with sesame seeds

   

   Finish the dish by lightly and evenly sprinkling white sesame seeds over the tuna and the ginger-shiso garnish to add a delicate crunch and nutty flavor.

   Tip: Toasted sesame seeds will provide an even deeper, nuttier fragrance.
