Full Ingredients

Rice

• 1 1/2 cups jasmine or sushi rice, rinsed until water runs mostly clear
• 2 1/4 cups water
• Pinch of kosher salt

Ginger–Soy Glaze

• 1/3 cup low-sodium soy sauce
• 2 tbsp unseasoned rice vinegar
• 1 tbsp honey
• 1 tbsp finely grated fresh ginger
• 1 small garlic clove, finely grated
• 1 tsp toasted sesame oil
• 1 tsp cornstarch mixed with 1 tsp water

Sesame-Crusted Tuna

• 4 ahi tuna steaks (6 oz each, about 1-inch thick), sushi-grade if serving rare
• 1/3 cup mixed white and black sesame seeds
• 2 tbsp neutral oil (avocado, canola, or grapeseed)
• Kosher salt and black pepper, to taste

Bowl Toppings

• 1 large avocado, sliced or fanned
• 1 small cucumber, thinly sliced (half-moons or ribbons)
• 4 scallions, thinly sliced
• Lime wedges, for serving (optional)

Step-by-Step Instructions

Step 1: Rinse and cook the rice

Rinse 1 1/2 cups rice under cool water, swishing, until the water runs mostly clear (about 30–60 seconds). Combine with 2 1/4 cups water and a pinch of salt in a saucepan. Bring to a boil, then cover and reduce to low. Simmer for 12 minutes. Remove from heat and keep covered for 10 minutes to steam. Fluff with a fork and keep warm.

Step 2: Whisk and reserve the ginger–soy glaze base

In a bowl, whisk together 1/3 cup soy sauce, 2 tbsp rice vinegar, 1 tbsp honey, 1 tbsp grated ginger, 1 small grated garlic clove, and 1 tsp toasted sesame oil. Measure out 2 tbsp of this mixture into a shallow dish and set aside for brushing the tuna. Pour the remaining mixture into a small saucepan. Stir the cornstarch with 1 tsp water to make a slurry, then whisk it into the pan. Bring to a gentle simmer over medium heat and cook, stirring, until glossy and slightly thickened, 2–3 minutes. Keep warm on low.

Step 3: Prep the toppings

Slice the avocado, thinly slice the cucumber (half-moons or ribbons), and cut the scallions. If you like, toss the cucumber with a pinch of salt and a splash (1 tsp) of rice vinegar for extra brightness.

Step 4: Coat the tuna with a sesame crust

Pat the tuna steaks very dry with paper towels and season lightly with salt and pepper. Brush all sides with the reserved 2 tbsp glaze base to moisten. Spread 1/3 cup sesame seeds on a plate and press each steak into the seeds to coat all sides evenly. Press gently so the seeds adhere.

Step 5: Sear the tuna hot and fast

Heat a cast-iron or heavy stainless skillet over medium-high until very hot, about 2 minutes (surface temperature around 400–450°F; a drop of water should sizzle instantly). Add 2 tbsp neutral oil; when it shimmers, add the tuna. Sear 45–60 seconds per side for rare, just until the sesame seeds are toasted and the outer 1/8 inch is opaque. Sear the narrow edges 10–15 seconds each if desired. Target internal temperatures: 110–115°F for rare, 120–125°F for medium-rare (use an instant-read thermometer inserted into the side). Transfer to a board and rest 2 minutes.

Step 6: Slice the tuna

Using a sharp chef’s knife, slice the tuna across the grain into 1/4-inch slices, wiping the blade as needed for clean cuts. The center should be rosy and translucent with a crisp sesame crust.

Step 7: Build the bowls

Divide warm rice among 4 bowls (about 1 to 1 1/4 cups each). Shingle the tuna slices on top. Add avocado, cucumber, and scallions. Spoon 1–2 tbsp warm ginger–soy glaze over each bowl. Finish with extra sesame seeds and a squeeze of lime, if using. Serve immediately.

Pro Tips

• Use sushi-grade tuna if serving rare; if you prefer, cook longer for medium-rare to medium, adding 15–30 seconds per side.
• Pat the tuna very dry before brushing with glaze—dry fish sears better and helps the sesame crust adhere.
• For even browning, preheat the pan thoroughly and do not overcrowd; sear in batches if needed.
• Reserve glaze for drizzling only from the cooked, thickened batch; the small portion used to brush the raw fish should not be reused.
• Warm bowls slightly (30 seconds in a low oven) so the rice stays steamy and the glaze stays glossy on contact.

Variations

• Spicy drizzle: Stir 1–2 tsp sriracha or chili crisp into the finished glaze.
• Furikake rice: Sprinkle hot rice with 1–2 tbsp furikake for extra umami and crunch.
• Grain swap: Try sushi rice, brown rice, quinoa, or cauliflower rice to suit your preferences.

Storage & Make-Ahead

Rice can be cooked up to 3 days ahead; refrigerate and reheat with a splash of water. The glaze can be made 3 days ahead and chilled; warm gently before serving. Tuna is best seared and eaten immediately for ideal texture. If you must store leftovers, refrigerate sliced tuna in an airtight container up to 24 hours and enjoy chilled (do not re-sear). Slice avocado just before serving to prevent browning.
