What Is a Spicy Salmon Sushi Bake?
A sushi bake is a deconstructed version of sushi — think of it as a layered sushi casserole that’s baked until warm and creamy, then scooped onto roasted seaweed sheets or eaten with chopsticks.
In this version, we use fresh or canned salmon, spicy mayo, sushi rice, and a savory mixture of sauces and toppings. The result? A spicy, creamy, and slightly crispy sushi experience that’s comforting and totally addictive.
It’s the ultimate mashup between Japanese sushi and modern comfort food!

How to Make Spicy Salmon Sushi Bake
Follow these simple steps for the perfect spicy salmon sushi bake every time.
Step 1: Prepare the Sushi Rice
- Rinse your sushi rice under cold water until the water runs clear.
- Add the rice and water to a rice cooker or pot and cook according to package directions.
- In a small bowl, whisk together rice vinegar, sugar, and salt until dissolved.
- Once the rice is cooked, gently mix in the vinegar seasoning with a rice paddle.
- Spread the seasoned rice evenly in a 9×9-inch baking dish (or similar size).
Step 2: Cook and Shred the Salmon
- Preheat your oven to 375°F (190°C).
- Line a baking sheet with foil and place your salmon fillet on it.
- Lightly season with salt and pepper. Bake for 12–15 minutes until fully cooked.
- Once cooked, use a fork to flake the salmon into small pieces.
Pro Tip: You can also use canned salmon for a quicker version — just drain and flake it before mixing.
Step 3: Make the Spicy Salmon Mixture
In a medium bowl, combine the flaked salmon with:
- Japanese mayo
- Sriracha
- Soy sauce
- Sesame oil
- Cream cheese (optional)
- Chopped green onion
Mix until everything is well combined and creamy.
Taste and adjust the spice level — add more Sriracha for extra heat or a bit more mayo for a milder flavor.
Step 4: Assemble the Sushi Bake
- Take your baking dish with the sushi rice base.
- Sprinkle a light layer of furikake over the rice.
- Evenly spread the spicy salmon mixture on top.
- Drizzle extra spicy mayo over the top (mix Kewpie mayo and Sriracha).
- Sprinkle with sesame seeds and a bit more furikake if you like.
Step 5: Bake Until Hot and Bubbly
Bake your sushi casserole in the preheated oven at 375°F (190°C) for 10–12 minutes, or until it’s warmed through and slightly golden on top.
For a slightly crispy, caramelized top, broil it for an additional 1–2 minutes — but watch carefully so it doesn’t burn.
Step 6: Garnish and Serve
Once baked, remove from the oven and let it cool slightly for 5 minutes.
Top with:
- Chopped green onions
- Fresh avocado slices
- A drizzle of extra spicy mayo or unagi (eel) sauce
Serve warm with roasted seaweed sheets (nori). Simply scoop some of the sushi bake with a spoon, place it on a nori square, and enjoy like a mini hand roll!
Spicy Mayo Recipe
Here’s the quick and easy spicy mayo recipe you’ll need:
- ½ cup Japanese mayo (Kewpie)
- 2 tablespoons Sriracha
- 1 teaspoon lime juice (optional for tang)
Mix everything in a small bowl and drizzle it over the sushi bake before and after baking. Adjust spice to taste.
Tips for the Perfect Spicy Salmon Sushi Bake
- Use sushi rice – Regular long-grain rice won’t have the right texture or stickiness.
- Kewpie mayo matters – Japanese mayonnaise gives a richer, umami flavor than American mayo.
- Don’t overbake – The goal is to warm the dish and lightly brown the top, not dry it out.
- Add crunch – Top with crushed roasted seaweed, tempura flakes, or panko for extra texture.
- Serve immediately – It tastes best warm, fresh from the oven.

How to Store and Reheat Sushi Bake
If you have leftovers (lucky you!), here’s how to keep them fresh:
- Refrigerate: Store in an airtight container for up to 3 days.
- Reheat: Bake in a preheated oven at 350°F (175°C) for about 10 minutes, or microwave for 1–2 minutes until warmed through.
- Do not freeze: The texture of sushi rice doesn’t hold up well when frozen.
