Taste and texture notes

This Spicy Tuna Poke Bowl relies on contrast. The marinade is savory and slightly acidic from the soy or tamari, with sesame oil adding a toasty note. A combination of light mayonnaise and sriracha creates a creamy, slightly spicy coating that clings to each tuna cube. Crisp cucumber and scallions provide freshness and crunch, while avocado brings a smooth, cooling element. A scattering of black sesame seeds finishes the bowl with a subtle nutty crunch and a pretty visual pop.

How to pick and prep ingredients

Start with truly sushi-grade tuna from a reputable fishmonger. The texture and flavor of the finished bowl depend on it. If you prefer a milder heat, reduce the sriracha; if you want a kick, add a touch more. Use short grain brown rice for a slightly nutty chew or sushi white rice for the classic poke texture. Peel the Persian cucumbers if their skins are waxed; otherwise leaving the skin on adds color and crunch.

Step-by-step instructions

1. Prepare the rice: If you haven’t already, cook 1 cup short grain brown rice or sushi white rice according to package directions. Fluff and keep warm while you prepare the other components.
2. Slice the scallions: Thinly slice 1/4 cup scallions. Reserve 2 scallions and slice them for garnish later.
3. Dice the cucumbers: Peel (if desired) and dice the Persian cucumbers into 1/2-inch cubes until you have 1 cup.
4. Cube the tuna: Cut 1/2 pound sushi grade tuna into 1/2-inch cubes. Place the tuna in a medium mixing bowl.
5. Make the savory dressing: In a small bowl, whisk together 2 tablespoons reduced sodium soy sauce or gluten-free tamari, 1 teaspoon sesame oil, and 1/2 teaspoon sriracha. Pour this mixture over the cubed tuna and gently toss so each piece is coated. Set aside to let the flavors marry for 2–5 minutes while you make the spicy mayo.
6. Make the spicy mayonnaise: In a separate small bowl, combine 2 tablespoons light mayonnaise and 2 teaspoons sriracha sauce. Stir until smooth. Taste and adjust the heat by adding more sriracha if you prefer it spicier.
7. Combine tuna with scallions and spicy mayo: Add the 1/4 cup sliced scallions to the marinated tuna. Spoon the spicy mayonnaise over the tuna and gently fold until the tuna cubes are evenly coated but still hold their shape.
8. Assemble the bowl: Divide 1 cup cooked rice between serving bowls. Top each bowl with half of the spicy tuna mixture, half of the diced cucumbers, and half of the avocado slices (from 1/2 medium Hass avocado total). Arrange the components so they sit side-by-side for visual appeal.
9. Garnish: Sprinkle the bowls with the reserved sliced scallions and 1 teaspoon black sesame seeds. For extra seasoning, offer reduced sodium soy or gluten-free tamari and additional sriracha at the table.
10. Serve immediately: Poke bowls are best fresh. Serve right away so the tuna stays cool and the avocado maintains its texture.

Quick tips and variations

• Make it less spicy: Reduce the sriracha in both the marinade and the mayo, or omit it from one of the components.
• Add crunch: Toss a handful of toasted nori strips, pickled ginger, or crushed macadamia nuts on top.
• Extra umami: A small drizzle of toasted sesame oil or a splash of ponzu (if available) at the end brightens the flavors.
• Vegetarian swap: Replace tuna with marinated pressed tofu cubes for a plant-based bowl while keeping the other flavors intact.
• Meal prep note: For make-ahead lunches, store components separately. Keep the dressed tuna chilled and assemble onto rice just before eating to prevent mushy textures.

Serving suggestions

Serve this Spicy Tuna Poke Bowl with a crisp green salad, miso soup, or steamed edamame. A chilled glass of green tea or a light citrusy white wine pairs nicely. If you like a little extra seasoning at the table, offer reduced sodium soy or gluten-free tamari and an extra bottle of sriracha.

Storage

Leftover dressed tuna is best eaten within 24 hours when stored in an airtight container in the refrigerator. Keep avocado slices separate and add them just before serving to avoid browning. Cooked rice can be refrigerated for up to 3–4 days; gently reheat before assembling bowls.

Nutrition snapshot (approximate per serving)
