Follow these steps to create your mouth-watering Spicy Salmon Sushi Bake:

1. Preheat Oven: Start by preheating your oven to 375°F (190°C).

2. Prepare Sushi Rice: Rinse the sushi rice under cold water until the water runs clear. Combine the rinsed rice and water in a rice cooker and cook according to the manufacturer’s instructions.

3. Cook Salmon: While the rice is cooking, place the salmon fillet in a baking dish. Bake it in the preheated oven for about 15-20 minutes or until fully cooked and flaky.

4. Flake Salmon: Once cooked, remove the salmon from the oven and use a fork to flake the fish into smaller pieces.

5. Make Spicy Salmon Mix: In a bowl, combine the flaked salmon, mayonnaise, Sriracha sauce, soy sauce, rice vinegar, green onion, and sesame oil. Mix until ingredients are well combined.

6. Season Rice: When the rice is done, fluff it with a fork. Season it with a little sea salt and stir gently to incorporate.

7. Layer Ingredients: In a baking dish, spread the cooked sushi rice evenly on the bottom. Press it down lightly to create an even layer.

8. Add Salmon Mixture: Spread the spicy salmon mixture over the layer of rice, ensuring it covers the rice evenly.

9. Bake: Place the dish back into the oven and bake for an additional 15 minutes until heated through.

10. Final Touches: Remove the dish from the oven and let it cool slightly. Optionally, top with diced cucumber, sliced avocado, and nori flakes for added flavor and a beautiful presentation.
