Creating this incredible Salmon Sushi Bake is simple if you follow these steps:

1. Preheat the Oven: Start by preheating your oven to 375°F (190°C).
2. Prepare the Rice: Rinse the sushi rice under cold water until the water runs clear. Combine the rice and water in a rice cooker and cook according to the manufacturer’s instructions. Alternatively, boil water in a pot, add rice, and reduce heat to low, covering the pot until the water is absorbed (about 18 minutes).
3. Cook the Salmon: While the rice cooks, season the salmon with salt and pepper. Place it in a baking dish and bake for about 15-20 minutes or until it flakes easily with a fork.
4. Make the Sauce: In a bowl, mix together the mayonnaise, sriracha sauce, sesame oil, rice vinegar, and sugar. Adjust seasoning to taste.
5. Flake the Salmon: Once cooked, remove the salmon from the oven and let it cool slightly. Flake the salmon into bite-sized pieces.
6. Combine Ingredients: In a large mixing bowl, combine the cooked rice, flaked salmon, diced avocado, chopped green onions, and the prepared sauce. Mix gently to combine without mashing the avocado.
7. Prepare for Baking: Spread the salmon mixture evenly in a greased baking dish.
8. Add Topping: In a separate bowl, mix the panko breadcrumbs with sesame seeds. Sprinkle this mixture evenly over the top of the salmon rice mixture.
9. Bake: Place the baking dish in the preheated oven and bake for 30-35 minutes or until the top is golden brown and crispy.
10. Cool and Serve: Remove from the oven and let it sit for 5-10 minutes before serving. Cut into squares and serve warm. You can also serve it with nori sheets for a fun sushi roll experience.
