If there is one dish that I would eat non-stop, it would be this vegan sushi bake. This bubbly, hot dish is so delicious, creamy, and even a little spicy. It has all the flavors that you'd expect in a typical roll, but deconstructed and in a casserole form. It's easy to make, mix the toppings, prepare the rice, and broil it for a few minutes. This is the perfect dish for upcoming parties and gatherings.

What is a vegan sushi bake? Think about it as a deconstructed sushi or even a sushi casserole. Using the same elements that you find in an American-style sushi roll. Yes, I said American-style. Traditional Japanese sushi doesn't contain mayonnaise, cream cheese, or even imitation crab meat. Anyway, then you broil it in the oven, to get a little char on the top and to melt everything together.Sushi bake is a local favorite, it started in Hawaii but made its way to my home island of Guam. It's such a rich and indulgent dish, that you'll keep wanting more!

✏️Ingredient Notes
- Sushi Rice - It wouldn’t be a sushi bake without rice!
- Oyster Mushrooms - The texture is kinda meaty and kinda chewy, which makes a perfect meat-free substitute in place of imitation crab meat.
- Vegan Mayonnaise - Normally, this dish uses Japanese mayonnaise. I haven’t found a vegan Japanese mayonnaise, so I’ve added a little bit of rice vinegar and agave to make it taste similar.
- Vegan Cream Cheese - It adds another level of creaminess to the dish and it tastes great with the rest of the ingredients.
- Sriracha - For added heat and flavor.
- Furikake - Adds a bit of nuttiness and other great flavors that make it taste like you’re eating sushi

🍴How to Make Vegan Sushi Bake
Top Tip: Use a food scale to weigh out the ingredients. That way, you'll only need one or two bowls, and you won't have to wash a bunch of measuring cups!

Step 1: Step 1: Cook rice as you normally would. I cooked mine in a rice cooker. Meanwhile, in a small bowl combine the unseasoned rice vinegar, granulated sugar, and salt. Heat it in the microwave for 15-20 seconds. Stir until the sugar and salt has dissolved.

Step 2: When the rice is done cooking, transfer it to a large bowl. Pour the vinegar mixture over, and fold the rice until it is well-coated. Place a towel over the bowl and allow it to cool to room temperature.

Step 3: In a bowl, add the cubed oyster mushrooms, soy sauce, onion powder, garlic powder, salt and pepper. Mix until well combined.

Step 4: Heat oil in a large pan over medium heat, and add in the seasoned mushrooms. Cook until they have softened slightly, about 5-7 minutes. Remove from heat and set aside until ready to use.

Step 5: Add the vegan mayonnaise, rice vinegar, agave, vegan cream cheese, and sriracha in a large bowl. Mix until well combined. Then add the cooked mushrooms and coat it in the sriracha mayo mixture.

Step 6: When the sushi rice has cooled completely, transfer it to a 9x13-inch baking dish. Spread it evenly, while making sure to lightly pack it down into the dish.

Step 7: Next, sprinkle an even layer of furikake over the top of the rice. Then add the mushroom mixture, and spread it evenly across. Sprinkle a little more furikake on the top.

Step 8: Place one of the racks in your oven to the top. Carefully place your baking sheet on the rack, and set your oven to high broil.

Step 9: Allow the top to broil for 3-5 minutes, or until bubbly. This will be a quick process, so you need to pay close attention. We don’t want it to burn!

Step 10: Remove from the oven and allow it to cool down before serving. Drizzle some teriyaki or unagi sauce and add some sliced avocado over top. Scooping the sushi bake onto a piece of seaweed snack. Enjoy!

⭐Expert Baking Tips
- If you can, use a rice cooker. This will save you so much time and save you from cooking one less thing over the stove.
- Use the right vegan cream cheese. I love using Kite Hill cream cheese for all of my recipes. It always turns out great, especially when baking. Other vegan cream cheese will completely melt off during baking.
- Do not skip out on the sushi rice vinegar. This mixture is what will give this recipe its sushi flavor.
💭Common Questions
I haven't personally tried it, but you could give short-grain brown rice a shot. But, I don't think it'd work for cauliflower rice. Sushi rice is kind of the star here because of its stickiness. That's what gives this dish its sushi-like texture.
I would not skip the sriracha as it adds flavor to this vegan sushi bake. However, if you’re worried about it being too spicy, reduce the amount or use a milder version of sriracha.

🍥How to Serve
Sushi bakes are eaten kind of like a taco, using a roasted seaweed snack or nori to hold it together. You can also serve it with some avocado over top and drizzle with a little bit of teriyaki sauce or even unagi sauce.
🥣Storage & Reheating
- You can store this vegan sushi bake in an airtight container in the fridge for about 3-4 days.
- You can easily reheat this in the microwave. Portion out a serving and place it in the microwave for about a minute.
- If you want to reheat the entire dish, you can place it in the oven at 325°F oven for about 10—15 minutes. Be sure to use a baking dish!

Floured Frame says

Tina Patel says
This was Amazing!!! I added some premade seasoned tofu i had leftover on top!!!
Could the rice recipe here be something that could be rolled and then baked into individual rolls?
Floured Frame says
I'm so glad you loved this recipe! So yes, the rice can be made into rolls! But if you're going to roll them using nori, I would be careful because it can react when it comes in contact with heat.
