Ingredients

Scale
  • 1 ½ cups sushi rice (short-grain rice works best for stickiness)
  • 2 cups water
  • 3 tablespoons rice vinegar
  • 1 tablespoon sugar
  • 1 teaspoon salt
  • 8 ounces imitation crab meat or cooked shrimp (shredded)
  • 1 cup mayonnaise (preferably Japanese Kewpie mayo)
  • 2 tablespoons Sriracha (adjust for heat preference)
  • 1 teaspoon soy sauce
  • 1 teaspoon sesame oil (optional)
  • 1 ripe avocado, sliced
  • 2 green onions, thinly sliced
  • 1 tablespoon toasted sesame seeds

Instructions

  1. Rinse 1 ½ cups sushi rice under cold water until water runs clear.
  2. Combine rinsed rice and 2 cups water in a medium saucepan. Bring to a boil, then reduce heat to low and cover. Simmer for 18 minutes without lifting the lid.
  3. Remove from heat and let sit, covered, for 10 minutes.
  4. In a small bowl, mix 3 tablespoons rice vinegar, 1 tablespoon sugar, and 1 teaspoon salt until dissolved.
  5. Transfer cooked rice to a large bowl and gently fold in the vinegar mixture. Spread the rice out to cool slightly (about 10 minutes).
  6. In a medium bowl, combine 1 cup mayonnaise, 2 tablespoons Sriracha, 1 teaspoon soy sauce, and 1 teaspoon sesame oil. Mix until smooth and creamy. Adjust spice level if needed.
  7. Spread the sushi rice evenly in a greased 9×9 inch baking dish, pressing down gently.
  8. Layer the shredded crab or shrimp evenly over the rice.
  9. Spoon the spicy mayo mixture evenly on top, smoothing it out.
  10. Arrange sliced avocado in a single layer on top of the spicy mayo.
  11. Sprinkle with sliced green onions and toasted sesame seeds for garnish.
  12. Preheat oven to 400°F (200°C). Bake for 12-15 minutes, or until the top is bubbly and golden brown at the edges.
  13. Remove from oven and let cool for 5 minutes before serving.

Notes

Rinse sushi rice thoroughly to remove excess starch for perfect stickiness. Use gluten-free soy sauce or tamari for gluten-free version. For dairy-free, substitute mayo with avocado spread or vegan mayo. Do not skip resting time after baking to allow flavors to meld. Tent with foil if spicy mayo browns too fast. Broil for 1-2 minutes at the end for extra crispiness, watching closely.
