Prepare the Sushi Rice: Begin by rinsing the sushi rice under cold water until the water runs clear. In a medium-sized pot, combine the rinsed rice with 2 cups of water. Bring to a boil, then reduce heat to low, cover, and cook for 18-20 minutes. Turn off heat and let it steam for an additional 10 minutes.
Season the Rice: In a small bowl, whisk together rice vinegar, sugar, and salt until dissolved. Transfer the cooked rice to a large bowl and gently fold in the vinegar mixture. Allow to cool slightly.
Make the Filling: In a separate bowl, combine shredded imitation crab meat, diced avocado, finely chopped cucumber, softened cream cheese, mayonnaise, and sriracha. Mix well and adjust sriracha to taste.
Assemble the Sushi Bake: Preheat oven to 350°F (175°C). Grease a 9x9 inch baking dish. Spread the seasoned sushi rice evenly in the dish and press down gently. Spread the crab mixture on top.
Bake: Place the dish in the oven and bake for 20-25 minutes until golden brown and bubbly.
Garnish and Serve: Remove from oven and let cool for a few minutes. Garnish with chopped green onions and sesame seeds. Serve with strips of nori.
Notes
Serve with extra sriracha on the side for added heat.
