Instructions

1. 1

   Cook the rice

   Rinse the rice in a fine-mesh strainer under cold water until the water runs clear. Add it to a medium pot with 590 ml (2½ cups) water and bring to the boil. Immediately turn the heat to its lowest setting, cover and simmer for 15–20 minutes, until the water has been absorbed. Remove from the heat and leave covered for 10 minutes.

2. 2

   Season the rice

   While the rice rests, whisk the rice vinegar, sugar and salt until dissolved. Once the rice has rested, fluff it with a fork or rice paddle and gently fold in the vinegar mixture.

3. 3

   Cut the tuna

   Pat the tuna dry with kitchen paper. With a sharp knife, cut it into even 1.3 cm (½-inch) cubes and put them in a medium non-reactive bowl.

4. 4

   Marinate the tuna

   In a separate small bowl, whisk together the low-sodium soy sauce, sesame oil, grated ginger and minced garlic. Pour over the tuna, then add the sweet onion and the white parts of the green onions. Toss gently and refrigerate for at least 10 minutes, but no longer than 30 minutes.

5. 5

   Build the bowls

   Divide the warm seasoned rice among four bowls. Spoon the marinated tuna over one side of each portion. Arrange the avocado, edamame, cucumber and pickled ginger around the tuna. Finish with the green parts of the green onions and sesame seeds, then serve immediately.

What is a poke bowl?

Poke is a Hawaiian dish whose name refers to fish cut into pieces, often served seasoned. This bowl takes that idea and pairs raw ahi tuna with sushi rice and a selection of toppings.

The combination works because the rice is gently tangy, the tuna brings savoury richness, and the vegetables add freshness and contrast. The assembled bowl is best eaten soon after the tuna has been marinated.

Nutrition and macros by portion

The nutrition label shows one serving as written: 730 calories, 58g protein, 91g carbs, 17g fat.

The rice supplies most of the carbohydrate, while the tuna and edamame contribute much of the protein. Sesame oil and avocado are the main sources of fat, with additional fat from the tuna. For a balanced plate, serve a generous amount of cucumber alongside the bowl.

Choose and cut the tuna carefully

Tuna: Use fish sold as sushi-grade or sashimi-grade, and keep it chilled until you are ready to prepare it. If you are unsure whether raw fish is suitable, ask your fishmonger for guidance.

Even cubes: Cutting the tuna into similarly sized pieces helps the marinade coat them evenly. A sharp knife also makes it easier to cut cleanly without crushing the fish.

Get the rice right

Rinsing: Wash the rice until the water runs clear to remove loose surface starch. This helps the cooked grains hold together without turning overly sticky.

Resting: Keep the lid on during the 10-minute rest after cooking. Fold in the vinegar mixture gently so the grains stay intact.

Keep the marinade brief

Timing: Refrigerate the tuna for at least 10 minutes and no more than 30 minutes, as directed. The short rest lets the soy, sesame, ginger and garlic season the fish without leaving it sitting in the marinade for too long.

Gentle mixing: Toss rather than stir vigorously, so the cubes keep their shape. Adding the sliced onions with the marinade gives them time to take on its savoury flavour.

Build contrasting textures

Fresh toppings: Avocado is soft and creamy, while cucumber gives a crisp counterpoint. Edamame adds a firm bite, and pickled ginger brings a sharp, sweet-sour note.

Finishing touches: Keep the green onion tops and sesame seeds for the final sprinkle. If using the optional toppings, add them at assembly so they remain distinct.

Serve it straight away

Temperature: The recipe pairs warm seasoned rice with chilled marinated tuna and toppings. Assemble just before eating so the rice and fresh ingredients keep their contrasting temperatures and textures.

On the side: A simple green salad or extra cucumber can round out the meal without competing with the bowl’s flavours. Divide the rice and toppings evenly to make four portions.

Recipe notes & tips

• Rinse the rice thoroughly before cooking.
• Keep the tuna refrigerated while preparing the other ingredients.
• Use a sharp knife to cut the tuna into even cubes.
• Measure the marinade time and keep it within the stated 10–30 minutes.
• Prepare the toppings before assembling so the bowls can be served promptly.

Variations

• Add seaweed salad: Spoon it alongside the other toppings for a briny contrast.
• Use tamari: Replace the soy sauce with the listed alternative.
• Add furikake: Sprinkle it over the finished bowls for an extra savoury finish.
• Make it spicy: Add the optional spicy mayonnaise at serving time.
• Toast the sesame seeds: Toast them briefly before sprinkling for a more fragrant finish.

Common mistakes to avoid

• Skipping the rice rinse: Wash until the water runs clear so excess surface starch is removed.
• Lifting the rice lid: Keep the pot covered while it simmers and during its 10-minute rest.
• Cutting uneven cubes: Aim for even 1.3 cm pieces so they are coated consistently.
• Marinating too long: Refrigerate for no more than 30 minutes, as the recipe directs.
• Assembling too early: Build the bowls just before serving to preserve the contrast between warm rice and chilled toppings.

How to store

For the best texture, serve the assembled bowls immediately. Refrigerate any leftover components promptly in separate airtight containers and use within 1 day; keep raw tuna cold and do not leave it at room temperature. Reheat only the rice, covered, until hot, then add the chilled tuna and toppings.
