Sushi Bake

Sushi Bake is a cozy, oven-baked twist on classic sushi that brings together seasoned sushi rice, salmon, imitation crab, creamy Japanese mayonnaise, and a little sriracha in one easy casserole-style dish. Instead of rolling individual sushi pieces, everything is layered in a baking dish and served with nori, seaweed snacks, or fresh toppings.

The base starts with sushi rice seasoned with rice vinegar, sugar, and salt. On top goes a savory seafood mixture made with cooked salmon, chopped imitation crab, Kewpie mayonnaise, soy sauce, sesame oil, and sriracha. Baking allows the flavors to meld together while warming the creamy topping.

Once the Sushi Bake comes out of the oven, you can finish it with spicy mayo, scallions, cilantro, sesame seeds, avocado, or cucumber. Scoop a little of the warm rice and seafood mixture onto a piece of nori or a seaweed snack, then eat it like a hand roll.

It’s an easy way to enjoy sushi-inspired flavors without the precision or time required to make traditional sushi rolls.

How to Make Sushi Bake

1. Cook the Sushi Rice

Rinse the sushi rice under cold water several times until the water runs mostly clear.

Cook the rice according to the package directions or using a rice cooker.

Once the rice is cooked, let it rest for about 5–10 minutes.

Transfer the warm rice to a large bowl.

In a small bowl, combine the rice vinegar, sugar, and salt. Stir until the sugar and salt are mostly dissolved.

Pour the mixture over the warm rice and gently fold it through using a rice paddle or spatula.

Avoid aggressively stirring or mashing the rice. You want to keep the grains intact while distributing the seasoning evenly.

Set the seasoned rice aside to cool slightly.

2. Cook the Salmon

Preheat your oven to 375°F (190°C).

Place the salmon fillet on a lightly greased or parchment-lined baking sheet.

Bake for approximately 12–15 minutes, depending on the thickness of the fillet.

The salmon should be cooked through and flake easily with a fork.

For food safety, check that the thickest part reaches 145°F (63°C).

Allow the salmon to cool slightly before flaking it into small pieces.

3. Prepare the Imitation Crab

While the salmon cooks, finely chop or shred the imitation crab.

You want relatively small pieces so the crab distributes evenly throughout the filling.

Place the crab in a large mixing bowl.

4. Make the Creamy Seafood Mixture

Add the flaked salmon and chopped imitation crab to the bowl.

Add the Kewpie mayonnaise, sriracha, soy sauce, and sesame oil.

Mix gently until everything is evenly coated.

Start with 1 teaspoon of sriracha if you’re sensitive to heat. You can add more later if you want a spicier filling.

Taste the mixture and adjust the seasoning if needed.

5. Prepare the Nori

Cut or crumble one nori sheet into small pieces.

Fold the nori into the seafood mixture and stir gently.

The nori adds the familiar roasted seaweed flavor associated with sushi.

You can also save the nori for serving instead of mixing it into the filling.

6. Assemble the Sushi Bake

Lightly grease an approximately 9×9-inch baking dish.

Spread the seasoned sushi rice evenly across the bottom.

Use the back of a spoon or a spatula to gently press the rice into an even layer.

Spread the salmon and imitation crab mixture over the rice.

Smooth the surface without pressing too firmly.

Sprinkle sesame seeds over the top.

7. Bake the Sushi Casserole

Place the assembled Sushi Bake in the preheated oven.

Bake for approximately 10–15 minutes, until the seafood mixture is hot and the edges are lightly bubbling.

If you want a more browned top, switch the oven to broil for 1–2 minutes at the end.

Keep a close eye on it during broiling because the mayonnaise-based topping can brown quickly.

8. Add the Fresh Toppings

Remove the Sushi Bake from the oven and let it rest for about 5 minutes.

Drizzle spicy mayonnaise over the top.

Add chopped scallions, cilantro, or black sesame seeds.

Arrange sliced avocado and cucumber on top or serve them on the side.

9. Serve with Nori

Cut or scoop the Sushi Bake into portions.

Place a spoonful onto a seaweed snack or piece of nori.

Add avocado, cucumber, or a little extra spicy mayo if desired.

Fold the nori around the filling and enjoy it like a casual sushi hand roll.

Recipe Tips for Success

Rinse the sushi rice well.
Removing excess surface starch helps produce rice with the sticky texture you want for Sushi Bake.

Don’t overwork the rice.
Fold the vinegar seasoning into the cooked rice gently to avoid turning it mushy.

Use cooked salmon.
The salmon should be fully cooked before the Sushi Bake is assembled. This also makes the filling easier to mix.

Adjust the sriracha gradually.
Start with a small amount and add more to taste. Different brands can vary considerably in heat.

Use Kewpie mayonnaise if you have it.
Kewpie has a richer, slightly tangy flavor that works especially well with the seafood mixture, although regular mayonnaise can be substituted.

Don’t make the seafood layer too thick.
An even layer helps the filling heat through without requiring excessive baking time.

Serve with crisp toppings.
Cucumber and scallions provide a fresh contrast to the creamy seafood and soft rice.

Don’t skip the nori.
Serving the Sushi Bake with seaweed snacks is what gives the dish much of its hand-roll-style eating experience.

Ingredient Substitutions

Sushi Rice

Short-grain Japanese rice is the best alternative. Other sticky short-grain rice varieties can work, although the texture may be slightly different.

Salmon

Cooked shrimp, canned salmon, or cooked tuna can be used instead. Make sure any seafood is fully cooked before assembling the casserole.

Imitation Crab

Cooked real crab meat can replace imitation crab if desired. Chopped cooked shrimp is another option.

Kewpie Mayonnaise

Regular mayonnaise works well if you don’t have Kewpie. For a tangier flavor, add a small splash of rice vinegar.

Sriracha

Use another chili sauce or your preferred hot sauce. You can also omit it completely for a mild Sushi Bake.

Soy Sauce

Tamari can be used instead of soy sauce. If using regular soy sauce, you may want to reduce the amount slightly because it can be saltier than low-sodium soy sauce.

Sesame Oil

Toasted sesame oil provides the strongest flavor, but regular sesame oil can also be used.

Cilantro

If you don’t enjoy cilantro, simply use scallions or leave the herb out.

Variations

Spicy Salmon Sushi Bake

Increase the sriracha and drizzle extra spicy mayo over the finished casserole. Add thinly sliced jalapeños for additional heat.

Shrimp Sushi Bake

Replace the salmon with cooked shrimp. Chop the shrimp into bite-sized pieces before combining it with the imitation crab and mayonnaise mixture.

California Roll Sushi Bake

Use imitation crab as the main protein and add avocado and cucumber generously when serving. This gives the casserole flavors reminiscent of a California roll.

Teriyaki Sushi Bake

Add a small drizzle of teriyaki sauce to the seafood mixture or over the finished casserole. Keep the amount moderate so the dish doesn’t become overly sweet.

Cream Cheese Sushi Bake

For a richer variation, add softened cream cheese to the seafood mixture. The creamy cheese pairs particularly well with salmon, crab, and spicy mayo.

Vegetarian Sushi Bake

Replace the seafood with roasted mushrooms, avocado, cucumber, edamame, and other sushi-inspired vegetables. Use a suitable plant-based mayonnaise if desired.

Extra-Crispy Top

After baking, broil the Sushi Bake for an additional minute or two until the top develops lightly browned spots. Watch carefully to prevent burning.

Storage and Reheating

Allow leftover Sushi Bake to cool before transferring it to an airtight container.

Refrigerate leftovers for up to 3 days.

Because this recipe contains cooked seafood and mayonnaise, keep it refrigerated promptly and avoid leaving it at room temperature for extended periods.

For the best texture, reheat individual portions in the microwave until hot throughout. You can also warm it in a covered oven-safe dish at 325°F (165°C) until heated through.

Fresh avocado and cucumber should be stored separately and added after reheating.

Store nori and seaweed snacks separately in a dry, airtight container so they remain crisp.

Freezing is not recommended for the best texture because the rice and creamy seafood mixture can change after thawing.

Serving Suggestions

Sushi Bake is especially fun when served as a build-your-own meal.

Put the warm casserole in the center of the table with bowls of toppings and let everyone assemble their own seaweed bites.

Serve it with:

• Nori sheets
• Seaweed snacks
• Spicy mayo
• Sliced avocado
• Cucumber
• Scallions
• Cilantro
• Sesame seeds
• Pickled ginger
• Edamame
• Japanese-style cucumber salad

For a simple dinner, pair the Sushi Bake with edamame and a crisp cucumber salad.

If you’re serving it as an appetizer, cut or scoop smaller portions and arrange the toppings separately so guests can build individual bites.

Frequently Asked Questions

What is Sushi Bake?

Sushi Bake is a baked, casserole-style dish inspired by sushi. It typically combines seasoned sushi rice with seafood, mayonnaise, sauces, and toppings, then gets baked and served with nori or seaweed snacks.

Do I have to use Kewpie mayonnaise?

No. Regular mayonnaise works well. Kewpie mayonnaise simply gives the filling a richer and slightly more savory-tangy flavor.

Can I use raw salmon?

For this recipe, the salmon should be cooked before it is mixed into the filling. Bake the salmon until fully cooked and flaky before assembling the Sushi Bake.

What kind of rice should I use?

Short-grain sushi rice is ideal because it becomes sticky enough to hold together when scooped onto nori. Follow the cooking instructions for your particular rice because water requirements vary by brand.

Can I make Sushi Bake ahead of time?

Yes. You can prepare the rice and seafood mixture ahead of time and refrigerate them separately. Assemble and bake when you’re ready to serve.

Can I make Sushi Bake without sriracha?

Absolutely. Simply leave it out for a mild version. You can also serve spicy mayo separately so everyone can control the heat.

What do you eat Sushi Bake with?

Sushi Bake is commonly served with nori sheets or seaweed snacks. You can scoop some of the warm mixture onto the seaweed and add avocado, cucumber, scallions, or spicy mayo.

How long does Sushi Bake last in the refrigerator?

Store leftovers in an airtight container and refrigerate for up to 3 days. Reheat thoroughly before eating and keep fresh toppings such as avocado and cucumber separate.

Final Thoughts

Sushi Bake takes the flavors of sushi and turns them into a simple baked dish that doesn’t require rolling, shaping, or special sushi-making skills. The seasoned sushi rice provides a sticky, lightly tangy base, while salmon, imitation crab, creamy mayonnaise, soy sauce, sesame oil, and sriracha create a savory seafood topping.

The best part is how easy it is to customize. Make it spicy, add avocado and cucumber, swap the salmon for shrimp, or serve everything with plenty of nori for a hand-roll-style meal.

For an easy dinner or a casual appetizer, this Sushi Bake delivers familiar sushi-inspired flavors in a much more relaxed format.
