Grilled Tuna Sashimi Bowl

Ingredients

Scale

8 oz sushi-grade tuna (ask your fishmonger specifically for this)
2 tbsp soy sauce (use the good stuff from the Asian section)
1 tbsp sesame oil (toasted, not light cooking oil)
1 tsp honey
1/2 tsp fresh ginger, grated (microplane works best)
1/4 cup cucumber, diced small and uniform
1/4 avocado, sliced (ripe but still firm)
1/2 cup cooked sushi rice (short-grain is traditional)
Sesame seeds and sliced green onions for garnish (don’t skip these)

Instructions

Preheat your grill or grill pan over high heat until it’s smoking hot—you should only be able to hold your hand 6 inches above it for 2-3 seconds.
In a small bowl, whisk together soy sauce, sesame oil, honey, and grated ginger until smooth and glossy—this becomes both marinade and finishing sauce.
Brush the tuna generously with marinade on both sides, but don’t let it sit longer than 2 minutes or the acid will start “cooking” the fish.
Grill the tuna for exactly 1-2 minutes per side for rare doneness (look for 1/4 inch golden crust with pink center)—resist the urge to move it before it’s ready.
Let the tuna rest for 3-4 minutes before slicing against the grain into thick pieces—this finishing step is crucial for perfect texture.
Place warm sushi rice in bowls and arrange sliced tuna, diced cucumber, and avocado in sections on top for that classic poke bowl presentation.
Drizzle with any remaining marinade and sprinkle generously with sesame seeds and green onions—serve immediately while the tuna is still warm.

Notes:

Sushi-grade fish is safe to eat raw—don’t overcook it out of unnecessary fear
Your grill must be blazing hot for proper searing—don’t rush this step
Slice against the grain for the most tender texture
If you’re nervous about doneness, 125°F internal temperature is perfect rare

Storage Tips:

This dish is best eaten immediately after preparation
Leftover components can be stored separately for up to 2 days
Don’t store already-grilled tuna—it’s never as good reheated
Prep rice and vegetables ahead but grill the fish fresh each time

Traditional style: Serve with pickled ginger and wasabi on the side
Dinner party mode: Present in individual ceramic bowls with chopsticks for elegant presentation
Lunch version: Pack rice and vegetables separately, grill tuna fresh when ready to eat
