Spicy Salmon Sushi Bake

The smell of sesame oil hitting warm rice always takes me straight back to my tiny apartment kitchen, where I first tried making this after scrolling too long through food videos at midnight. I had leftover salmon from dinner, a craving I couldn't shake, and zero patience for rolling individual sushi pieces. What came out of the oven that night was messy, bubbly, and so good I texted photos to three different people before I even sat down to eat. This dish taught me that sometimes the best recipes happen when you stop trying to be perfect and just layer flavors you love into one beautiful, shareable pan.

I made this for a small birthday gathering once, and I watched four grown adults hover around the pan with forks, too impatient to wait for me to portion it out. One friend who swore she didnt like cooked salmon went back for thirds. There's something about the way the rice gets lightly crisp on the edges, the way the spicy mayo melts into every layer, that turns skeptics into believers. It became my go-to whenever I want to feed people something that feels special but doesn't chain me to the stove.

Ingredients

• Sushi rice: Short-grain rice is essential here because it holds together and gets sticky in the best way, creating a cohesive base that you can scoop without it falling apart.
• Rice vinegar, sugar, and salt: This trio seasons the rice with that classic sushi tang and subtle sweetness, and I learned the hard way not to skip this step or your base will taste flat.
• Skinless salmon fillet: Fresh or frozen works, just make sure its boneless and patted dry before baking so it flakes beautifully and doesn't water down your topping.
• Mayonnaise (preferably Kewpie): Kewpie is richer and slightly sweeter than regular mayo, and it makes the spicy salmon mixture taste more authentic and luxurious.
• Sriracha sauce: This brings the heat and a little vinegar brightness, and you can dial it up or down depending on who youre feeding.
• Soy sauce: Adds salty umami depth that ties the whole dish together, use tamari or gluten-free soy sauce if needed.
• Toasted sesame oil: Just a couple teaspoons give the salmon mixture a nutty, roasted flavor that makes it taste like it came from a restaurant.
• Green onion: Finely chopped and stirred in, it adds a pop of freshness and a mild bite that cuts through the richness.
• Nori sheet: Crumbled over the rice, it brings that authentic seaweed flavor without overwhelming the dish.
• Shredded mozzarella cheese: Optional but highly recommended, it melts into a golden, bubbly top layer that adds creaminess and a little indulgence.
• Toasted sesame seeds: Sprinkled on top for crunch and a nutty finish that makes everything look polished.
• Avocado: Sliced and laid over the top just before serving, it adds cool creaminess and a pop of green that balances the heat.
• Roasted seaweed snacks: Perfect for scooping, they add crunch and make eating this feel interactive and fun.

Instructions

Prepare the sushi rice:

Rinse the rice under cold water until it runs clear to remove excess starch, then cook it in a rice cooker or pot with the water until tender and glossy. In a small saucepan, gently heat the rice vinegar, sugar, and salt until the sugar dissolves, then fold this mixture into the cooked rice while its still warm so it absorbs all that tangy sweetness.

Bake the salmon:

Preheat your oven to 200 degrees Celsius, place the salmon on a parchment-lined baking sheet, brush it lightly with neutral oil, and bake for 12 to 15 minutes until it flakes easily with a fork. Let it cool slightly, then break it into small, bite-sized pieces that will mix easily into the spicy topping.

Make the spicy salmon mixture:

In a mixing bowl, combine the flaked salmon, mayonnaise, sriracha, soy sauce, sesame oil, and chopped green onion, stirring gently until everything is well blended and creamy. Taste it and adjust the sriracha if you want more heat or add a touch more mayo if you prefer it milder.

Assemble the bake:

Lightly oil a 9x9-inch baking dish, spread the seasoned sushi rice evenly across the bottom, and press it down gently with a spatula so it forms a compact layer. Sprinkle the crumbled nori over the rice, then spread the spicy salmon mixture on top, and finish with shredded mozzarella if youre using it.

Bake until bubbly:

Slide the dish into your preheated oven and bake for 10 to 12 minutes, just until the top is heated through, the cheese is melted and bubbling, and the edges start to turn golden. Let it cool for about 5 minutes before garnishing so you dont burn your tongue in your excitement.

Garnish and serve:

Sprinkle toasted sesame seeds over the top, lay sliced avocado across the surface, and drizzle with extra sriracha and mayonnaise in a zigzag pattern for that classic sushi bar look. Serve it warm with roasted seaweed snacks on the side for scooping, or just grab a fork and dig in.

Pin it

There was one evening when I made this for a friend going through a rough week, and we sat on the floor with the pan between us, scooping it onto seaweed crisps and talking until the dish was empty. She told me later it was the first time she'd felt calm in days. Food like this does more than fill you up, it creates a moment, a memory, a small pocket of comfort that lingers long after the last bite.

Storing and Reheating

Leftovers keep well in an airtight container in the fridge for up to three days, and I actually think the flavors deepen overnight as the rice soaks up more of the spicy mayo. Reheat individual portions in the microwave for about a minute, or warm the whole dish in a 180-degree oven for 10 minutes until heated through. If the rice seems a little dry after reheating, a quick drizzle of soy sauce or a dab of mayo brings it back to life.

Customizing Your Bake

This recipe is endlessly adaptable, and I have swapped the salmon for lump crab meat, cooked shrimp, or even spicy tuna when I am feeling fancy. If you want extra crunch, layer in thinly sliced cucumber, pickled radish, or even crispy fried onions before baking. For a vegetarian version, try using marinated tofu or a mix of sauteed mushrooms with the same spicy mayo treatment, it is surprisingly satisfying and just as craveable.

Serving Suggestions

This pairs beautifully with a simple cucumber salad dressed in rice vinegar and a pinch of sugar, or a cold glass of sake if you are in the mood to make it feel like a real occasion. I have also served it alongside miso soup and edamame for a full Japanese-inspired spread that feels special without being complicated.

• Offer extra sriracha, soy sauce, and mayo on the side so everyone can customize their heat and creaminess levels.
• If you are serving a crowd, double the recipe and use a 9x13-inch pan, it scales up perfectly and disappears just as fast.
• Leftover seaweed snacks can be crumbled over the top for extra umami crunch right before serving.

This dish has earned a permanent spot in my rotation because it delivers restaurant flavors with minimal fuss and maximum comfort. I hope it becomes one of those recipes you turn to when you want to feel like you are treating yourself, even on the most ordinary Tuesday.

Recipe FAQs

→ What makes this different from regular sushi rolls?

This deconstructed version layers seasoned sushi rice with spicy salmon filling in a casserole format, then bakes it until warm and bubbly. It eliminates the rolling technique while delivering all the classic flavors in a shareable, family-style dish.

→ Can I make this ahead of time?

Yes, assemble the entire dish up to 24 hours in advance and refrigerate. When ready to serve, bake for 15-18 minutes until heated through. Leftovers reheat well in the oven at 350°F for 10-12 minutes.

→ What's the best way to serve sushi bake?

Serve warm, scooped onto roasted seaweed snacks, crackers, or small bowls of seasoned rice. Offer extra sriracha and mayonnaise for drizzling, along with pickled ginger, wasabi, or additional avocado on the side.

→ Can I substitute the salmon?

Cooked crab meat, imitation crab, or even shredded cooked chicken work well as alternatives. For a vegetarian version, use seasoned tofu, mushrooms, or a mix of roasted vegetables with the same spicy mayo coating.

→ Is Kewpie mayonnaise necessary?

Kewpie mayonnaise has a richer, eggier flavor than regular mayonnaise due to using egg yolks instead of whole eggs. While it's traditional, regular mayonnaise works fine in a pinch. Add a touch of MSG or dashi powder to mimic the umami depth.

→ How spicy is this dish?

With 2-3 tablespoons of sriracha, it delivers a moderate heat that's approachable for most palates. Adjust the amount up or down based on your spice tolerance. The creamy mayonnaise and rice help balance the heat.
