This recipe is a trendy, oven‑baked sushi casserole that layers seasoned sushi rice with a creamy mixture of salmon, sautéed mushrooms, spring onions, cream cheese, mayo, and Sriracha, then bakes it until warm and flavorful before serving it with chopped nori sheets. The dish takes all the beloved elements of sushi — seasoned rice and savory toppings — and turns them into a comforting, easy‑to‑prepare baked meal, with options to swap in tuna, shrimp, or other proteins and add vegetables for a healthier twist.
