Full Ingredients

Microwave Sushi Rice

• 1 cup (200 g) sushi rice (short-grain Japanese rice)
• 1 1/4 cups (300 g) water
• 2 tbsp rice vinegar
• 1 tbsp granulated sugar
• 1/2 tsp fine salt

California Roll Bowl Toppings

• 6 oz (170 g) imitation crab, shredded (or 6 oz/170 g cooked shrimp, chopped)
• 1/2 medium cucumber, diced (about 1 cup / 130 g)
• 1 medium avocado, diced
• 1 tsp toasted sesame seeds
• 1/2 cup crushed seaweed snacks (about 10–12 snack sheets, crushed)
• Optional: 2 tsp soy sauce, for serving

Light Sriracha-Mayo Drizzle

• 2 tbsp mayonnaise
• 1 to 2 tsp sriracha (use 1 tsp for mild, 2 tsp for medium-spicy)
• 1 tsp water (to thin to a drizzle)

Step-by-Step Instructions

Step 1: Rinse and drain the sushi rice

Place 1 cup (200 g) sushi rice in a fine-mesh sieve. Rinse under cool running water, stirring the rice with your fingers, until the water runs mostly clear (usually 45–60 seconds). Let it drain well for 1 minute so you don’t start with excess water.

Step 2: Microwave the rice (covered)

Add the drained rice to a medium microwave-safe bowl (at least 2-quart capacity to prevent boil-overs). Pour in 1 1/4 cups (300 g) water and stir once.

Cover with a microwave-safe lid or plate (leave it slightly vented so steam can escape). Microwave on High (100%) for 5 minutes, then reduce power to 50% and microwave for 10 minutes.

Important: Keep the bowl covered and let the rice rest for 10 minutes after microwaving. This finishing steam is what makes the texture tender instead of crunchy.

Step 3: Season the rice like sushi rice

While the rice rests, stir together in a small bowl: 2 tbsp rice vinegar, 1 tbsp sugar, and 1/2 tsp fine salt until the sugar dissolves (about 30 seconds).

After the 10-minute rest, uncover the rice and gently fluff with a fork or rice paddle. Drizzle the vinegar mixture over the hot rice and fold gently until evenly coated. Let the rice cool for 5 minutes so it’s warm (not piping hot) when you add the toppings.

Step 4: Prep the bowl toppings

While the rice cools, prep your toppings:

Shred or chop 6 oz (170 g) imitation crab (or chop 6 oz cooked shrimp). Dice 1/2 medium cucumber (about 1 cup / 130 g). Dice 1 medium avocado.

Crush seaweed snack sheets into small flakes (you want pieces you can sprinkle, not a fine powder). Measure 1/2 cup crushed.

Step 5: Mix a light sriracha-mayo drizzle

In a small bowl, whisk together 2 tbsp mayonnaise, 1 to 2 tsp sriracha, and 1 tsp water until smooth and drizzleable. If you want it thinner, add another 1/2 tsp water.

Step 6: Assemble the sushi bowls

Divide the seasoned rice between 2 bowls. Arrange the imitation crab (or shrimp), cucumber, and avocado on top in sections so each bite gets a little of everything.

Step 7: Finish with sesame, seaweed, and sauce

Drizzle the sriracha-mayo over each bowl. Sprinkle with 1 tsp toasted sesame seeds (total for both bowls) and a generous pinch of crushed seaweed snacks.

Taste and, if you like, finish with soy sauce (about 1 tsp per bowl) right before eating.

Pro Tips

• Microwave power varies: These times are designed for a 1000-watt microwave. If your rice seems a little firm after resting, microwave at 50% power for 2 more minutes, then rest covered 5 minutes.
• Prevent boil-overs: Use a bowl that’s at least 2-quart capacity and keep the cover slightly vented.
• Best rice texture: Season the rice while it’s hot so it absorbs the vinegar mixture evenly, then cool briefly so the avocado doesn’t get warm and mushy.
• Seaweed timing: Add crushed seaweed right before eating to keep it crisp.
• Clean avocado cubes: Dice avocado in the skin, then scoop with a spoon for neat pieces.

Variations

• Spicy “crab” bowl: Mix the shredded imitation crab with 1 tbsp mayonnaise and 1 tsp sriracha, then pile it on top and skip the drizzle (or drizzle lightly).
• Shrimp California bowl: Use 6 oz cooked shrimp (thawed if frozen), chopped. Add a squeeze of 1 tsp fresh lime juice over the shrimp for a brighter flavor.
• Extra crunch bowl: Add 2 tbsp panko breadcrumbs toasted in a dry skillet for 2–3 minutes (optional), or top with extra cucumber and sesame.

Storage & Make-Ahead

For the freshest “sushi” vibe, these bowls are best eaten right after assembling.

Make-ahead: You can cook and season the rice up to 24 hours ahead. Cool completely, then store airtight in the refrigerator. For best texture, re-warm gently in the microwave at 50% power for 45–60 seconds (add 1 tsp water and cover) to take the chill off before assembling.

Storage: Store leftovers in separate containers if possible (rice, toppings, and sauce) for up to 2 days. Add seaweed snacks only at serving time so they stay crisp.
