Ingredients You’ll Need

The magic of this Easy Spicy Tuna Sushi Bake (Using Canned Tuna!) lies in its straightforward ingredients. Each component plays a vital role in building layered flavors and pleasing textures, from the creamy avocado to the tangy rice seasoning.

• Nori sheets (10 sheets, cut in half): These provide the classic sushi seaweed flavor and make perfect wraps for serving.
• Furikake (1 tbsp, optional): A Japanese rice seasoning that adds an extra touch of umami and crunch.
• Sesame seeds (1 tsp, optional): For a nutty aroma and a subtle crunch that complements the rice.
• Avocado (4 medium, ripe): Adds a luscious creaminess that balances the spicy tuna perfectly.
• Japanese mayo (2-5 tbsp): The key to that silky, slightly sweet mayo layer; regular mayo works in a pinch.
• Sriracha sauce (2-4 tbsp): Brings heat and depth to the tuna mix and a drizzle on top.
• Green onion (1, finely chopped): Freshness and a pop of color as garnish.
• Vegetable oil (1 tsp): Used to grease the baking dish so the rice doesn’t stick.
• Canned tuna in oil (15.87 oz total, drained): The star protein—drain well to avoid sogginess; canned salmon works as a tasty variation.
• Short-grain rice (1.5 cups uncooked): Perfect sushi rice with sticky texture to hold everything together.
• Rice vinegar (1 tbsp): Provides that signature sushi rice tang.
• White granulated sugar (2 tsp): Balances the vinegar with a touch of sweetness.
• Salt (about 3/4 tsp total): Enhances all the individual flavors.

How to Make Easy Spicy Tuna Sushi Bake (Using Canned Tuna!)

Step 1: Prepare Your Baking Dish and Cook Rice

Start by greasing a 9×9-inch baking dish with vegetable oil. This simple step makes cleanup easier and ensures your sushi bake won’t stick. Next, cook your short-grain rice following the package instructions so it’s perfectly tender yet sticky—this foundation is crucial for the dish’s structure.

Step 2: Season the Rice

While the rice is still hot, transfer it to a large bowl and gently stir in salt, sugar, and rice vinegar. This seasoning brings that classic sushi rice flavor alive. Then, spread the rice evenly into the greased baking dish and press it down firmly for a compact base that’s easy to slice later.

Step 3: Sprinkle Furikake and Sesame Seeds

Evenly scatter furikake and sesame seeds over the rice layer. These tiny extras pack a punch in flavor and texture, giving your sushi bake that authentic Japanese flair and a slight crunch.

Step 4: Mix the Spicy Tuna

Drain your canned tuna thoroughly, pressing out as much liquid as possible to avoid sogginess. In a medium bowl, combine the tuna with Japanese mayo, sriracha sauce, and salt for a creamy, spicy filling. Spread this mixture evenly over the rice base.

Step 5: Add Avocado and Drizzle Sauce

Thinly slice ripe avocados and arrange them beautifully over the tuna layer. Then, generously drizzle a mixture of Japanese mayo and sriracha sauce on top—this layer adds richness and an irresistible spiciness that will bubble up beautifully under the broiler.

Step 6: Broil until Bubbly and Golden

Place the sushi bake under a 500°F broiler for about 10 minutes, until the top is golden and bubbly. This step caramelizes the sauce and brings warmth to the entire dish—a truly tantalizing sight and aroma!

Step 7: Garnish and Serve

Once out of the oven, sprinkle finely chopped green onions across the top for freshness and color. Slice into 20 pieces with a wet knife to keep the layers neat. Serve by scooping a portion onto nori sheets—then enjoy the perfect handheld sushi bake experience.

Side Dishes

Creative Ways to Present

Try serving the sushi bake in mini mason jars for an elegant individual portion or layer the ingredients in clear glass dishes so guests can admire the beautiful layers before digging in. Alternatively, spread the bake on a large platter surrounded by nori squares for a fun interactive meal.

Make Ahead and Storage

Storing Leftovers

Store any leftover sushi bake in an airtight container in the refrigerator for up to 2 days. Keep the nori separate to avoid sogginess. When ready to eat, simply scoop out the portion and reheat gently.

Freezing

While freezing is possible, it may slightly alter the texture of the avocado and rice. If you want to freeze, wrap portions tightly with plastic wrap and place in a freezer bag. Consume within one month for best quality.

Reheating

Reheat leftovers in the oven at 350°F for about 10 minutes or until warmed through. Avoid the microwave if possible to keep the rice from becoming too mushy, and add fresh toppings after reheating to refresh the taste and texture.

FAQs

Can I use canned salmon instead of tuna?

Absolutely! Canned salmon works wonderfully in this recipe and offers a slightly different but equally delicious flavor profile.

Is it necessary to use Japanese mayo?

Japanese mayo has a lighter, tangier taste that complements sushi flavors perfectly, but regular mayo can be used as a substitute without losing much in taste.

Can I make this recipe vegan?

You can adapt it by replacing tuna with mashed chickpeas or shredded hearts of palm and swapping mayo for a vegan alternative. The avocado and rice layers still bring plenty of delicious texture!

What rice can I use if I don’t have short-grain sushi rice?

Short-grain rice is ideal for stickiness and texture, but medium-grain rice can be an acceptable substitute. Avoid long-grain rice, as it will be too loose to hold together.

How spicy is this dish?

The heat comes mainly from the sriracha, which you can adjust to your taste. Start with less if you’re sensitive to spice and add more as you like—it’s easy to customize!
