I’ve made sushi bake for casual dinners, potlucks, and lazy weekend feasts — it hits the sushi craving without the rolling. This layered, broiled “sushi casserole” is creamy, crunchy, and surprisingly easy to scale for a crowd. If you want a one-dish, finger-food way to serve sushi flavors at home, this is it — and it’s a great intro before trying more hands-on sushi recipes like my go-to spicy salmon sushi bake.
Why you’ll love this dish
Sushi bake takes all the beloved elements of sushi — seasoned rice, mayo-spiced seafood, nori, furikake — and turns them into a shareable pan that’s quick to assemble. It’s perfect for weeknight dinners, potlucks, or when you want the sushi taste without rolling. It’s budget-friendly (imitation crab stretches a pound of protein), kid-approved (mild and creamy), and easy to adapt for dietary needs.
“Perfectly creamy, lightly charred on top, and everyone loved building their own bites — an instant crowd-pleaser.” — a regular at my dinner table
How this recipe comes together
Step-by-step overview:
- Cook and season short-grain sushi rice so it’s sticky and slightly glossy.
- Toss shredded imitation crab with mirin, sake, soy, sugar and a quick broil-friendly binder (Kewpie mayo).
- Spread rice in a baking dish, top with the crab mixture, and broil to get a golden, slightly caramelized finish.
- Finish with spicy mayo, sliced cucumber and avocado, furikake, and tear-and-share nori or seaweed snacks for scooping.

What you’ll need
- 2 cups sushi rice (medium or short-grain — yields about 4 cups cooked)
- 1/4 cup rice vinegar (regular — NOT seasoned)
- 1 1/2 tablespoons granulated sugar (for rice)
- 1 teaspoon salt (for rice)
- Toasted sesame oil (a few drops to grease the pan; optional)
- 1 pound imitation crab meat (surimi), shredded
- 1/2 cup Kewpie mayo (for crab mixture)
- 1/4 cup Kewpie mayo (for spicy mayo base)
- 1 tablespoon Sriracha (adjust to taste)
- 2 tablespoons sake
- 2 tablespoons soy sauce (light sodium)
- 2 tablespoons granulated sugar (for crab seasoning)
- 1 tablespoon mirin
- English cucumber, thinly sliced
- Avocado, sliced
- Furikake (for sprinkling)
- Seaweed snacks or nori sheets, for scooping
Notes/substitutions inline:
- Kewpie mayo gives that authentic umami creaminess; use regular mayo if necessary, but add a teaspoon of rice vinegar or a drop of MSG for depth.
- Sake and mirin add a subtle sweetness; if unavailable, use an extra tablespoon of mirin or a mix of 1 tbsp rice vinegar + 1 tsp sugar.
- For gluten-free, use tamari instead of soy sauce and ensure imitation crab is gluten-free.
Directions to follow
Make the sushi rice:
- Rinse rice under cold water until the water runs almost clear to remove surface starch.
- Cook rice in a rice cooker or on the stovetop with 2 cups rice + 2.2–2.5 cups water (follow your cooker’s directions for best results).
- While hot, transfer rice to a wide bowl. Gently fold in 1/4 cup rice vinegar, 1 1/2 tbsp sugar, and 1 tsp salt. Fan or stir gently to cool and gloss the grains. Set aside.
Make the crab mixture:
- Preheat oven broiler to high.
- Shred or chop 1 lb imitation crab into bite-size pieces.
- In a bowl, whisk 1/2 cup Kewpie mayo, 2 tbsp sake, 2 tbsp soy sauce, 2 tbsp sugar, and 1 tbsp mirin until smooth.
- Toss the crab in the sauce until well-coated. Taste and adjust sweetness or salt.
For the spicy mayo:
- Mix 1/4 cup Kewpie mayo with 1 tbsp Sriracha. Taste and add more Sriracha if you want more heat.
(Optional) For the unagi-style glaze:
- Simmer 1/4 cup soy sauce, 2 tbsp sugar, and 1 tbsp mirin until slightly thickened for a quick unagi-like drizzle. Cool before using.
Assemble and bake:
- Grease a 9×9-inch or similar shallow baking dish with a drop of toasted sesame oil (optional).
- Press the seasoned sushi rice evenly into the dish to form a compact base.
- Spoon and spread the crab mixture over the rice in an even layer.
- Broil 3–6 minutes until the top is bubbling and just golden — watch closely to avoid burning.
- Remove and let rest 2 minutes.
Serve:
- Drizzle spicy mayo over the top in a zigzag.
- Sprinkle furikake liberally.
- Arrange sliced cucumber and avocado on the side or layer on top.
- Break seaweed snacks or cut nori into squares for scooping. Serve warm and let everyone build their bites.
Best ways to enjoy it
- Serve family-style straight from the baking dish with seaweed snacks on the side for scooping.
- Offer small bowls of pickled ginger, soy sauce, and extra Sriracha.
- Pair with a crisp salad (sesame dressing), miso soup, or edamame for a fuller meal.
- For parties, provide individual plates and let guests top their bites with scallions, tobiko, or a drizzle of the optional unagi-style glaze.
Storage and reheating tips
- Refrigerator: Store leftover sushi bake in an airtight container for up to 3 days. Keep the avocado and cucumber separate if you expect leftovers.
- Freezing: Not recommended for the assembled bake (textures degrade). You can freeze the crab mixture in a sealed container for up to 1 month; thaw in the fridge before baking.
- Reheating: Reheat single servings in a 375°F (190°C) oven for 8–12 minutes until warm through, or microwave covered for 60–90 seconds. Finish under the broiler 30–60 seconds if you want to re-crisp the top.
- Food safety: Don’t leave the dish at room temperature more than 2 hours, especially with mayo-based toppings.
Pro chef tips
- Use a wide, shallow dish so more surface gets browned under the broiler.
- Cool the rice just enough to handle; warm rice compacts better. If it’s steaming hot, the top layer may become soggy.
- Press the rice firmly but gently; compact rice holds the crab layer and makes scooping easy.
- Taste the crab mixture before baking — flavors concentrate when heated.
- For a cleaner presentation, pipe the spicy mayo in a squeeze bottle.
Creative twists
- Real crab or shrimp: Substitute lump crab or chopped cooked shrimp for a premium version.
- Spicy tuna bake: Replace crab with chopped sushi-grade tuna tossed in spicy mayo for a tuna bake variant.
- Vegetarian: Use diced king oyster mushrooms or hearts of palm tossed with the same sauce and a touch of sesame oil.
- Vegan: Swap Kewpie for vegan mayo, use coconut aminos instead of soy, and choose vegan “crab” alternatives.
- Extra crunch: Top with panko mixed with a little oil and broil briefly for a crunch layer.
Your questions answered
Q: How long does this take to make?
A: Active time is about 30 minutes (most of that is prepping), plus time to cook rice (20–30 minutes depending on method). Plan ~1 hour total.
Q: Can I make it ahead and reheat?
A: You can assemble and refrigerate for up to 24 hours before broiling, but for best texture broil just before serving. Store leftovers refrigerated for up to 3 days.
Q: Is imitation crab safe to use and does it taste ok?
A: Yes — imitation crab (surimi) is cooked and safe. It’s a budget-friendly, mild option that works well in this creamy, flavored bake.
Q: Can I use regular mayo instead of Kewpie?
A: Yes, but Kewpie has a slightly sweeter, richer umami profile. If using regular mayo, add a teaspoon rice vinegar or a pinch of sugar for balance.
Q: Can I freeze the finished dish?
A: Freezing the fully assembled bake is not recommended; textures change. Freeze the crab mixture separately for up to a month.
