This Japanese-inspired casserole transforms sushi into an effortless, shareable dish. Tender salmon bakes with seasoned rice, gets topped with a creamy Sriracha-mayo blend, and finishes with nori, avocado, and furikake. Ready in 45 minutes, it feeds six and works beautifully for gatherings or meal prep. Serve warm with pickled ginger and extra drizzles of unagi sauce.
The first time I made sushi bake, my roommate stood in the doorway watching me flake salmon into a bowl, looking completely betrayed that I was dismantling something we usually paid twenty dollars a roll for. Twenty minutes later, she was sitting on the kitchen floor with a spoon, scraping the corners of the baking dish and admitting maybe I was onto something. Now it's the only thing I make when friends come over and nobody wants to spend three hours rolling sushi.
Last winter my sister brought home three different kinds of store-bought sushi for what she called a taste test, and we ended up arguing about which was better until I remembered I had salmon in the fridge. We baked this instead, and halfway through eating, she stopped mid-sentence and said this was better than anything we'd bought, including the expensive place downtown.
Ingredients
- 2 cups sushi rice: Short-grain rice creates that signature sticky texture that holds everything together
- 2 1/4 cups water: The exact ratio matters for fluffy, perfectly cooked grains
- 3 tablespoons rice vinegar: This is what gives restaurant-style sushi rice its distinct tangy sweetness
- 1 tablespoon sugar: Balances the vinegars sharpness and helps the rice gloss
- 1 teaspoon salt: Enhances all the other flavors without making it taste salty
- 500 g skinless salmon fillet: Fresh salmon flakes beautifully but canned salmon works in a pinch
- 1 tablespoon soy sauce: Adds umami depth to the salmon as it bakes
- 1 tablespoon lemon juice: Brightens the rich salmon and cuts through the creamy layers
- 1 teaspoon sesame oil: Gives a subtle nutty aroma that smells like real sushi
- 1/2 teaspoon black pepper: A little heat that balances the richness
- 1/2 cup mayonnaise: Japanese Kewpie mayo is richer but regular mayo works fine
- 2 tablespoons Sriracha: Adjustable based on how much spice you want
- 100 g cream cheese: Makes the salmon mixture creamy and luxurious
- 2 sheets roasted nori: Cut into small strips for that crunch and seaweed flavor
- 2 tablespoons furikake seasoning: The rice seasoning that ties everything together
- 2 green onions: Fresh bite that cuts through the warm, rich layers
- 1 ripe avocado: Adds cool creaminess against the hot bake
- 1 tablespoon toasted sesame seeds: Final crunch and nutty garnish
Instructions
- Prep the rice foundation:
- Rinse the sushi rice under cold water until the water runs clear, then cook it with water in a rice cooker or on the stovetop. While still hot, fold in the rice vinegar, sugar, and salt, then let it cool slightly before spreading evenly into a lightly greased 9x13-inch baking dish.
- Bake the salmon:
- Preheat your oven to 200°C (400°F) and place the salmon fillet on a lined baking tray. Brush it with soy sauce, lemon juice, and sesame oil, sprinkle with black pepper, and bake for 12–15 minutes until cooked through, then cool slightly and flake into chunks.
- Mix the creamy salmon filling:
- In a bowl, whisk together the mayonnaise, Sriracha, and softened cream cheese until completely smooth. Gently fold in the flaked salmon until everything is well combined.
- Assemble and bake:
- Spread the salmon mixture evenly over the rice layer in your baking dish and sprinkle furikake seasoning across the top. Bake for 10 minutes until everything is heated through and slightly golden on top.
- Add the fresh toppings:
- Remove from the oven and immediately garnish with nori strips, green onions, sliced avocado, and toasted sesame seeds. Drizzle with extra Sriracha or unagi sauce if desired, and serve warm while the avocado is still cool against the hot bake.
My friend's eight-year-old, who claims to hate fish, took one suspicious bite and then proceeded to eat three bowls, picking out all the avocado pieces first like she'd discovered a hidden treasure. Now she requests it for her birthday dinner every year.
Making It Your Own
Once you make this a few times, you will start improvising with whatever you have on hand. I have used crab meat instead of salmon, added cucumber for crunch, and even thrown in masago when I wanted to feel fancy.
Serving Suggestions
Set out small bowls and let everyone build their own perfect bite. Some people go heavy on the avocado, others want extra Sriracha, and I have seen friends fight over the corner pieces with the most crispy rice edges.
Storage And Reheating
This keeps surprisingly well in the refrigerator for up to two days, though the avocado will brown so add it fresh when serving. Reheat individual portions in the microwave for about a minute, or cover the whole dish with foil and warm it in a 350°F oven until heated through.
- Let leftovers come to room temperature before reheating for the best texture
- A splash of water helps keep the rice from drying out in the microwave
- The flavors actually meld together overnight, so day-two leftovers are somehow better
There is something genuinely satisfying about scooping up that first bite, all the warm and cool and crunchy and creamy elements coming together in one spoon. It is comfort food that feels like an indulgence but comes together on a weeknight.
Recipe FAQs
- → Can I make this ahead of time?
-
Prepare components separately up to a day in advance. Store seasoned rice, cooked salmon, and creamy mixture in the refrigerator. Assemble and bake just before serving for the best texture and flavor.
- → What can I substitute for salmon?
-
Canned salmon works well for convenience. Crab sticks, shredded imitation crab, or cooked shrimp make excellent alternatives. For a vegetarian version, use marinated tofu or roasted vegetables.
- → Is this gluten-free?
-
The dish contains gluten in soy sauce and possibly furikake. Use tamari instead of soy sauce and verify your furikake is gluten-free. Serve with gluten-free nori sheets to complete the dish safely.
- → How spicy is the bake?
-
With 2 tablespoons Sriracha, the flavor offers moderate heat that's approachable for most palates. Adjust spice levels by reducing Sriracha for milder flavor or increasing it for extra kick. The cream cheese and mayonnaise help balance the heat.
- → Can I freeze leftovers?
-
Freezing affects the rice texture, making it less ideal. Refrigerate leftovers in an airtight container for up to 3 days. Re individual portions gently in the microwave or oven until warmed through.
