Start by rinsing the sushi rice under cold water, making sure the water runs clear to remove excess starch. In a rice cooker or pot, combine the rinsed rice and water. Cook according to your rice cooker’s instructions, or if using a pot, bring the mixture to a boil, then lower the heat and cover. Let it simmer for 20 minutes. After cooking, allow the rice to sit covered for an additional 10 minutes off the heat for perfect texture.
In a small bowl, whisk together the rice vinegar, sugar, and salt until fully dissolved. Pour this flavorful mixture over the warm rice. Gently fold it into the rice using a spatula, taking care not to smash the grains. Let the rice cool slightly to room temperature.
In a medium mixing bowl, combine the shredded imitation crab, diced avocado, finely chopped cucumber, mayonnaise, sriracha, and sesame oil. Mix everything until well combined, tasting as you go to adjust the sriracha to your preferred spice level.
Preheat your oven to 375°F (190°C).
Lightly grease a muffin tin with cooking spray or oil. Take a small handful of sushi rice and press it firmly into the bottom of each muffin cup, creating a layer that's approximately 1/4 inch thick.
Spoon the crab mixture generously over each rice layer in the muffin cups, filling each to just about the top. Ensure you pack it gently to avoid compressing it too much.
Carefully place the muffin tin in your preheated oven. Bake for 15-18 minutes, or just until the tops are lightly golden and the filling is warmed through.
Once baked, remove the muffin tin from the oven and let it cool for a few minutes. Gently run a knife around the edges to help release the sushi cups, then carefully lift them out. Garnish each cup with small squares of nori and a sprinkle of chopped green onions for that final touch.
Serve your delicious Sushi Bake Cups with soy sauce on the side for dipping. Enjoy this fun and flavorful twist on sushi!
Notes
Adjust the sriracha to your preferred spice level.
