Sushi bake makes homemade sushi approachable. Instead of rolling individual rolls, layer everything in a baking dish—seasoned sushi rice, a creamy crab filling, and toppings—bake until hot and bubbly, then scoop onto nori sheets and eat with your hands.
It’s the same flavors as a California roll, in casserole form. And it’s genuinely easier than rolling sushi, which makes it one of the best “fun dinner” recipes for a weeknight, a date night, or a small gathering.
This version is built directly on the Japanese crab salad recipe from the previous post.
That salad — creamy, high-protein, and made with real lump crab, Japanese mayonnaise, cucumber, and a light soy-lemon dressing — becomes the filling for the bake. Combined with a little softened cream cheese for a bake-friendly texture, it holds up beautifully in the oven and scoops cleanly onto nori.
About 24–26 grams of protein per serving with real lump crab.
One honest thing to know: add avocado after baking, not before. Avocado turns brown and mushy in the oven. Slicing it fresh over the top once it comes out of the oven is what makes this dish look and taste like a California roll instead of a green-tinged casserole.
Why This Crab and Avocado Sushi Bake Works
It’s sushi flavors without the rolling. Seasoned sushi rice, creamy Japanese crab salad, avocado, sesame, and spicy mayo—layered in a baking dish and scooped onto nori sheets: same taste, much less technique.
The Japanese crab salad is the filling. Built with Japanese-style mayonnaise, rice vinegar, soy sauce, and toasted sesame oil, it already tastes like sushi filling. Adding a little softened cream cheese gives it the body it needs to bake without becoming runny.
Seasoned sushi rice is the foundation. Short-grain rice with rice vinegar, sugar, and salt gives you that unmistakable sushi flavor and helps the bake hold together when you scoop it.
Real lump crab is the star. About 17–20g of protein per 3.5 ounces. Imitation crab works as a budget substitute, but the protein count drops significantly.
Spicy mayo drizzle on top is non-negotiable. It’s the finishing touch that makes a sushi bake taste like sushi, not a seafood casserole.
It’s baked, not just assembled. The oven melts the cream cheese into the crab salad and warms the rice through. The edges get slightly crispy, which is the best part.
It’s a one-dish meal. Sushi rice, protein, and toppings in a single pan. Serve it family-style and let everyone scoop their own.
It reheats beautifully. Unlike rolled sushi, a sushi bake holds up in the fridge for 3 days and reheats in 90 seconds.
It’s a fun dinner. It’s the kind of dish people photograph and ask about. Serve it at a party and watch it disappear.
Creamy Crab and Avocado Sushi Bake
A creamy, high-protein sushi bake made with seasoned sushi rice, a Japanese-style crab salad filling, and fresh avocado.
Bake in one dish, then scoop onto nori sheets.
Ingredients
For the sushi rice:
- 2 cups short-grain sushi rice, rinsed
- 2½ cups water
- 3 tbsp rice vinegar
- 1 tbsp sugar
- 1 tsp kosher salt
For the filling:
- 1 full batch Japanese Crab Salad Recipe (about 1½ cups)
- 4 oz cream cheese, softened to room temperature
For the toppings:
- ¼ cup Japanese mayonnaise
- 1–2 tbsp sriracha
- 1 tbsp toasted sesame seeds
- 2 green onions, thinly sliced
- 2 avocados, sliced (added after baking)
- Nori sheets, for serving
- Soy sauce, wasabi, and pickled ginger, for serving
Instructions
1. Cook the sushi rice. Rinse the sushi rice under cold water until the water runs mostly clear. Cook with the water in a rice cooker or on the stovetop, following the package directions. Let it cool slightly.
2. Season the rice. While the rice is still warm, stir in the rice vinegar, sugar, and salt. Fold gently with a spatula. Let the rice cool to room temperature.
3. Make the Japanese crab salad. Prepare the full batch of Japanese crab salad following the linked recipe. Refrigerate it while you assemble the rest of the bake so the filling firms up slightly.
4. Enrich the filling. In a large bowl, beat the softened cream cheese with a hand mixer or a spatula until smooth. Add the chilled crab salad and fold gently with a spatula until just combined. Keep the crab lumps intact — don't over-stir.
5. Assemble the bake. Lightly grease a 9x13 baking dish or a 10-inch cast iron skillet. Spread the seasoned sushi rice across the bottom in an even layer, pressing gently with a spatula to compact it. Spoon the crab and cream cheese filling over the rice in an even layer.
6. Make the spicy mayo drizzle. In a small bowl, whisk together the Japanese mayonnaise and sriracha. Drizzle it over the crab filling in a zigzag pattern.
7. Bake at 400°F for 18–22 minutes, until the filling is hot and bubbly and the edges are lightly golden. If you want a deeper golden top, broil on HIGH for 1–2 minutes at the end — watch closely, because the mayo can go from golden to burnt quickly.
8. Add the avocado and toppings. Remove the bake from the oven and let it rest for 5 minutes. Scatter the sliced avocado over the top, then sprinkle with sesame seeds and green onions.
9. Serve family-style with nori sheets on the side. Scoop the bake onto a nori sheet, fold it like a taco, and eat it by hand. Serve with soy sauce, wasabi, and pickled ginger on the side.
Notes
Protein per Serving: About 24–26g
Nutrition note: Protein varies significantly depending on whether you use real crab or imitation crab in the crab salad. Real lump crab delivers about 17–20g protein per 3.5 oz; imitation crab delivers about 6–8g. Calculate with your specific ingredients for accurate numbers.
Tips for the Best Sushi Bake
Make the crab salad first and chill it. The Japanese crab salad needs to chill for at least 15–20 minutes before you use it, for both flavor and texture. Making it the night before works beautifully too.
Use short-grain sushi rice, not long-grain. Short-grain rice is sticky and holds together when you scoop it onto the nori. Long-grain rice falls apart.
Season the rice while it’s still warm. The vinegar, sugar, and salt absorb better into warm rice. Let it cool to room temperature before assembling so it doesn’t melt the cream cheese.
Soften the cream cheese to room temperature. Cold cream cheese won’t blend smoothly — it’ll leave lumps. Leave it on the counter for 30 minutes, or microwave it in 10-second bursts.
Fold, don’t stir. The crab salad already has delicate lumps of crab. Folding the cream cheese in gently keeps those lumps intact. Stirring turns the filling into a paste.
Press the sushi rice firmly into the dish. Compacting the rice helps it hold together when you scoop it. Use the back of a spatula to press it into an even layer.
Add the avocado after baking. Avocado turns brown and mushy in the oven. Slicing it fresh over the top once it comes out of the oven is what makes this dish look and taste like a California roll.
Watch the broiler closely if you use it. Mayo and cream cheese go from golden to burnt in about 60 seconds. Stay by the oven.
Don’t overbake. Everything in the bake is already cooked. The oven’s job is to heat the filling and melt the cream cheese. 18–22 minutes is plenty.
Serve with nori sheets and a spoon. The whole point of a sushi bake is to scoop it onto nori and eat it with your hands. Set out a stack of nori and let people build their own.
For meal prep, portion into containers and reheat gently. A sushi bake holds up in the fridge for up to 3 days. Reheat in the microwave for 90 seconds with a splash of water. Add fresh avocado after reheating.
Easy Variations
California Roll Bake
Use imitation crab (surimi) instead of lump crab in the Japanese crab salad. Prepare the salad with the spicy kani variation and add 1 diced avocado to the filling before baking. Top with additional fresh avocado after baking.
Salmon Sushi Bake
Skip the crab salad and use 1½ lbs of cooked salmon, flaked into bite-size pieces. Toss the salmon with the same Japanese dressing — mayonnaise, lemon, Dijon, rice vinegar, soy sauce, sesame oil, green onions, and cucumber — then fold in the cream cheese. About 26–28g of protein per serving.
Spicy Kani Sushi Bake
Double the sriracha in both the crab salad and the drizzle. Use imitation crab and add an extra teaspoon of rice vinegar and a teaspoon of toasted sesame oil to the salad. It’s the spicy version you’ll find at many sushi restaurants.
Healthy Sushi Bake (Lower Carb)
Swap the sushi rice for cauliflower rice seasoned with rice vinegar, sugar, and salt. This drops the carbs significantly while still delivering the sushi flavor—about 22g of protein and 8g of net carbs per serving.
Storage and Food Safety
Refrigerator: Store in an airtight container for up to 3 days. The rice firms up in the fridge — add a splash of water when reheating.
Freezer: Not recommended. The rice and cream cheese texture suffer after freezing.
Reheating: Reheat individual portions in the microwave for 90 seconds with a splash of water. Add fresh avocado and sesame seeds after reheating.
Food safety: Sushi bake is a cooked dish, but it contains perishable seafood and dairy. Refrigerate within 2 hours of cooking, and don’t leave it at room temperature for more than 2 hours.
Frequently Asked Questions
What is a sushi bake?
A sushi bake is a casserole-style dish that layers seasoned sushi rice, a creamy seafood filling, and toppings in a baking dish. Bake until hot and bubbly, then scoop onto nori sheets and eat with your hands. It has the same flavors as a sushi roll without the rolling.
Do I need to make the Japanese crab salad first?
Yes. The crab salad is the filling for the bake. Make it first, chill for 15–20 minutes, then fold in the softened cream cheese and bake.
How much protein is in each serving?
About 24–26g per serving with real lump crab meat in the crab salad, or about 15–18g per serving with imitation crab. The exact number depends on the crab you use and your portion size.
Can I use imitation crab instead of real crab?
Yes. Imitation crab (surimi) is much cheaper and works beautifully in the crab salad. Flake it into small pieces rather than leaving it in large lumps. Just know that the protein count drops significantly.
Why did my sushi bake turn out watery?
Almost always because the cucumber in the crab salad wasn’t squeezed dry enough, scoop the seeds out of the cucumber, dice it, then wrap it in a clean kitchen towel and wring it out before adding it to the salad.
Can I make this ahead of time?
You can assemble the bake up to 24 hours ahead, cover, and refrigerate. Add 5–10 minutes to the bake time since it’ll go into the oven cold. For the best texture, add the avocado fresh after baking.
Can I freeze sushi bake?
Not recommended. The rice and cream cheese texture suffers after freezing. This dish is best eaten fresh or within 3 days.
What kind of rice should I use?
Short-grain sushi rice. It’s sticky and holds together when you scoop it onto nori. Long-grain rice falls apart.
Do I have to use nori sheets?
Nori is the traditional way to eat a sushi bake, and it’s what makes it taste like sushi. You can also scoop it into lettuce cups, eat it with a fork, or serve it over greens.
Is this recipe gluten-free?
Not as written — soy sauce contains gluten. Use tamari or a gluten-free soy sauce in the crab salad, and confirm your mayonnaise, Dijon, and any seasonings are gluten-free. Everything else is naturally gluten-free.
What do I serve with sushi bake?
Serve with nori sheets, soy sauce, wasabi, pickled ginger, a simple cucumber salad, and edamame. A glass of cold sake or green tea rounds it out.
