Ingredients for a Sushi Bake

  • Fish: Fresh salmon and tuna make great toppings for this sushi bake. You can also add other fish, such as imitation crab, octopus, or red snapper. Canned tuna or salmon will also work for a sushi bake.
  • Sushi rice: It’s best to buy rice that is specifically for sushi. You can find it on Amazon or at most grocery stores. Sushi rice has more starch than regular Jasmine rice, which makes it ideal for sushi and will absorb seasonings well.
  • Kewpie Mayo: Also known as Japanese mayo, this ingredient is slightly different than American mayonnaise. It’s slightly sweeter and has a slightly different flavor profile.
  • Sriracha: A bit of spice will kick up this sushi bake. Add it into the fish or use a store-bought spicy mayo instead. (Tip: spicy mayo is kewpie mayo and sriracha mixed together. Save yourself one ingredient by mixing the Japanese mayo and Sriracha together.
  • Avocado: Adding avocado slices for serving add a nice fattiness to the sushi bake.
  • Persian cucumbers: Slices of cucumber added to the sushi bake will give some crunch, well-needed texture, to this casserole.
  • Unagi Sauce: Find this ingredient at an Asian grocery store or online. It will add sweetness to the casserole, so add as little or as much as you’d like to the dish.

How to Make a Sushi Bake with Salmon and Tuna

The first step in making this sushi bake is to make the sushi rice.

Wash your sushi rice until the water is clear. Make your sushi rice according to the package instructions. Make about 1 cup of rice, this should yield a little less than three cups of cooked sushi rice.

While the rice is cooking, cut up your tuna and salmon into small pieces. Add the fish to two separate bowls and add in 3 tablespoons of kewpie mayo and Sriracha if desired. Mix well and set aside.

Once the sushi rice is finished cooking, add in the rice vinegar and mix well. Add the seasoned sushi rice to a casserole dish.

Top the rice on one side with the salmon and the other side with the tuna. Top your casserole with unagi sauce and spicy mayo.

After adding the fish, add your sauces of choice – I recommend spicy mayo and unagi sauce. You can serve the sushi bake like this and add your favorite toppings or you can bake it.

Broil the casserole dish for 3 to 5 minutes – until the fish is slightly seared and the sauce looks baked. Broil for more or less time depending on how well-done you like your fish.

Making sushi rice is much easier than you might think.

The most important step when making sushi rice is making sure you purchased the correct type of rice. The package will say “sushi rice” on it, but don’t confuse sushi rice with glutinous rice, sweet rice or Jasmine rice.

There should be directions on the back that will tell you how to cook your sushi rice.

You should rinse the rice well with cold water. I usually rinse the rice about 3 times, until the water that drains from the rice is no longer murky.

Add more water than you would to your standard Jasmine rice. For reference, you will want about 2 cups of water for every 1.5 cups of rice.

Other Toppings for a Sushi Bake

The best part of making a sushi bake at home is the seemingly unlimited possibilities for different toppings. Customize the toppings as spicy, sweet or umami.

One of my favorite toppings (for really any dish!) is a spicy homemade garlic chili oil. If you want to avoid the spice, but enjoy a sweet tang, you can top your sushi bake with teriyaki sauce or even a ponzu sauce substitute.

More Recipes with Sushi Rice

There are many ways to use your seasoned sushi rice. Now that you purchased a bag of sushi rice, I’m sure you’ll be looking for more ways to use it!

A fan favorite (and kid favorite!) are these Spicy Salmon Pizza Sushi Bites. They’re a great appetizer and a fun way to serve sushi at home.

You can also make poke bowls at home with similar ingredients as this sushi bake. If you have any leftover fish, simply add it on top of sushi rice and toppings of your choosing, such as avocado, cucumber, seaweed salad and edamame.
