Step-by-Step Instructions

Making this casserole is simpler than you’d think. Here’s exactly how to build it:

Step 1: Prepare Your Ingredients

Get your 8×8 or 9×9 baking dish ready and preheat your oven to 375°F. This is also when you’ll want to have your salmon flaked or cubed, rice cooled, and all your toppings prepped and within arm’s reach.

Step 2: Make the Spiced Mayo

In a small bowl, whisk together the mayo, rice vinegar, soy sauce, sriracha, and sesame oil until smooth. This becomes your flavor foundation, so taste it and adjust the sriracha if you like more heat.

Step 3: Layer the Rice

Spread the cooled rice evenly across the bottom of your baking dish. Press it down gently so it creates a solid base. This rice layer is your substitute for the nori wrapper in traditional sushi.

Step 4: Add Salmon and Mayo Mixture

Fold the flaked salmon together with about 3/4 of the spiced mayo until everything is coated. Spread this mixture evenly over the rice layer, making sure it covers everything.

Step 5: Bake

Pop the casserole into your preheated oven for 15 minutes. You’re looking for the salmon to heat through and the edges to get just slightly crispy.

Step 6: Top and Finish

Remove from the oven and immediately arrange the nori strips on top, followed by avocado slices, cucumber, pickled ginger, and a sprinkle of sesame seeds. Drizzle the remaining spiced mayo over everything and add a handful of green onions.

Step 7: Serve

Slice into pieces and serve immediately while everything is warm and the layers are still distinct. Add extra sriracha mayo on the side if you want more heat and richness.

Pro Tips for Perfect Results

Keep these strategies in mind to nail it every single time:

• Fresh is better: If you can get fresh salmon instead of canned, definitely go for it. It gives the dish a richer, more luxurious feel, though canned works beautifully too and costs way less.
• Rice temperature matters: Make sure your rice is completely cooled before assembling. Warm rice can make everything soggy and mess with the texture.
• Don’t skimp on nori: That crispy seaweed layer is essential for authentic sushi flavor. Tear or cut it roughly for easy eating and maximum nori in every bite.
• Layer mindfully: The key to restaurant-quality presentation is arranging your toppings thoughtfully after baking. It shows off all the beautiful colors and textures.

Real seafood chefs always say: The best sushi bake is the one that celebrates fresh ingredients without overthinking it. Let simplicity be your secret weapon.

Storage and Make-Ahead Tips

This casserole is perfect for planning ahead:

• Refrigerator: Store leftovers in an airtight container for up to 2 days. It actually tastes great cold the next day, or pop it in a 300°F oven for 5 minutes to warm through gently.
• Freezer: You can freeze the assembled casserole (before adding fresh toppings) for up to 1 month. Thaw overnight in the fridge, then bake as directed.
• Make-ahead strategy: Prep your rice and seasonings the day before. Assemble everything in the morning, cover it, and bake when you’re ready for dinner.

Fun fact: Sushi originated in Southeast Asia as a way to preserve fish by fermenting it with rice, making it one of the oldest preserved dishes in culinary history.
