California Roll Sushi Bake Recipe: Creamy Baked Sushi Casserole

This sushi bake captures the flavors of a California roll with far less work, making it perfect for weeknight dinners or parties. It’s a crowd-pleaser that disappears fast whether you serve it family-style or let guests assemble their own bites at the table.

Originally a viral favorite in the Philippines, sushi bake also gained popularity in the U.S. during lockdowns when dining out and restaurant sushi were less accessible. Once you try it, though, it’s easy to see why it has staying power: it’s delicious, customizable, and much quicker than rolling large quantities of sushi.

In our home this recipe has become a weekly ritual. There are countless variations, but here I share a classic California roll–style version: seasoned sushi rice, nori, creamy crab, cucumber, avocado, and a few finishing sauces and seasonings for maximum flavor with minimal fuss.

How to Make Sushi Rice

Good sushi rice starts with three basics: use short- or medium-grain rice, rinse it thoroughly, and cook it following the package directions. I usually use a consistent medium-grain rice, but short-grain is ideal if you have it. Long-grain will work in a pinch, though the texture won’t be as authentic. Avoid instant/minute rice.

If you prefer brown rice, you can substitute it, but be aware the texture and flavor of the finished bake will differ. I recommend rinsing the rice until the water runs mostly clear. That removes dust and excess bran from polishing and prevents overly sticky rice and off aromas.

To rinse, place the rice in the pot you’ll cook it in, cover with cool water, swirl and rub the grains gently, then drain. Repeat three to four times until the water is clear. Cook rice in a rice cooker, Instant Pot, or a heavy-bottomed saucepan with a tight-fitting lid.

How to Cook Sushi Rice on the Stove Top

Combine rinsed rice and water in a medium saucepan and bring to a boil over high heat, stirring only occasionally. When it boils, reduce heat to low, cover tightly, and simmer 15 minutes. Remove from heat and let stand, covered, 10 minutes. While the rice rests, warm rice vinegar with sugar and salt until dissolved, then drizzle over the hot rice and toss to coat evenly.

What is Furikake

Furikake is a common Japanese dry seasoning made from shredded nori (seaweed), toasted sesame seeds, bonito flakes, salt, sugar, and other flavorings. It’s traditionally sprinkled on cooked rice, fish, or vegetables. For this sushi bake, sprinkle furikake over both the rice and the creamy crab layer for an umami boost.

If you don’t have furikake, you can pulse nori sheets in a food processor and mix with toasted sesame seeds and a pinch of salt as a close substitute.

What is Imitation Crab Meat?

Imitation crab is not crab, but it’s real fish—typically deboned and minced fish turned into surimi, then seasoned and shaped to mimic crab. It’s an economical, tasty stand-in that’s commonly used in California rolls and works wonderfully in sushi bake. If you prefer, substitute cooked crab meat instead.

Leftover real crab can be repurposed in crab rangoon or other dishes if you do choose to splurge on fresh crab for this recipe.

What Ingredients Do I Need for Sushi Bake

Along with medium-grain rice, imitation crab and cream cheese, you’ll need mayonnaise, sriracha, sesame oil, furikake, nori, and green onions. Optional finishing sauces include unagi (eel) sauce, oyster sauce, or teriyaki glaze. Kewpie mayonnaise gives the nicest flavor and a tidy squeeze-bottle drizzle, but regular mayo works—just pipe it through a small corner snip of a sandwich bag for the same effect.

Lightly brushing the baking dish with sesame oil adds a subtle nutty aroma. If you don’t have sesame oil, use a light coating of vegetable or peanut oil.

How to Make Nori Snacks

If you can’t find pre-cut toasted seaweed snacks, make them at home. Preheat oven to 400ºF. Lightly brush nori sheets with toasted sesame oil on one side and sprinkle with salt. Toast in a single layer on a baking sheet until crisp, about 8–10 minutes. Cool and cut into rectangles for serving.

Sushi Bake

Preheat oven to 400ºF and lightly brush a 9×13-inch baking dish with toasted sesame oil. Cook the rice according to package instructions and, while it rests, heat rice vinegar with sugar and salt until dissolved. Drizzle the seasoned vinegar over the hot rice and toss to combine. Spread the rice in the prepared pan with lightly wet hands, forming an even layer without compressing it. Generously sprinkle furikake over the rice.

In a bowl, mash softened cream cheese with mayonnaise, sriracha (adjust to taste), and a splash of pickled ginger brine if you have it. Fold in flaked imitation crab meat. Dollop the creamy crab mixture over the rice and spread evenly. Sprinkle more furikake over the top and drizzle unagi sauce, extra mayonnaise, and a little sriracha decoratively if desired.

Bake for 10–12 minutes until heated through and the rice is sizzling. Remove from the oven and let rest 5–10 minutes. Scatter sliced green onions on top, then cut into rectangles while the bake is still in the pan. Use a narrow flexible spatula to lift portions out. Serve with toasted nori rectangles, diced cucumber, and sliced avocado so diners can assemble their own bites.

This sushi bake delivers the flavor of a California roll with a fraction of the effort, making it excellent party food that vanishes quickly. It’s easy to adapt—swap or add ingredients to suit your taste—and perfect for feeding a crowd.
