Volcano Roll

WANT TO SAVE THIS RECIPE?

I’ve always had a soft spot for sushi, but nothing quite satisfies my craving like a Volcano Roll. It’s the kind of roll that makes a statement the moment it hits the plate—steamy, spicy, and draped in a luscious creamy sauce that melts into each bite. The first time I made it at home, I was shocked by how quickly it disappeared. The flavor is complex but approachable, and the texture contrast—soft avocado, tender spicy topping, and chewy sushi rice—makes each bite irresistible.

What sets this roll apart from your typical sushi is that it’s built for drama. I’m talking about broiled spicy mayo-topped seafood cascading over neatly wrapped rolls of avocado and rice. You don’t need to be a sushi chef to pull it off either. With a little prep and the right ingredients, anyone can make a Volcano Roll that looks like it came from a restaurant.

What Kind of Sushi Rice Should I Use?

For the best Volcano Roll, short-grain Japanese sushi rice is non-negotiable. It’s sticky enough to hold the roll together but still tender and fluffy. After cooking, I always season it with a mixture of rice vinegar, sugar, and salt—this gives it that signature tang and a glossy finish. Avoid using long-grain or jasmine rice; they won’t stick properly and will fall apart when you roll.

Options for Substitutions

Not every ingredient needs to be set in stone when making a Volcano Roll. You can adjust it based on dietary needs or preferences:

• Seafood: Traditional volcano rolls use spicy baked scallops or imitation crab, but shrimp or even tofu can be used as a substitute.
• Avocado: Adds a creamy texture, but cucumber or mango can be swapped in for a crunchier or fruitier twist.
• Spicy Mayo: A mix of mayo and sriracha, but vegan mayo or Greek yogurt works great too.
• Sauce Topping: Instead of eel sauce, try soy glaze or teriyaki for a slightly different sweetness.
• Toppings: I love finishing with green onions and sesame seeds, but crispy onions or tobiko can add extra crunch or color.

Feel free to get creative while still staying true to that layered, molten character that makes a Volcano Roll unforgettable.

Ingredients for this Volcano Roll

• Sushi Rice – The backbone of any good roll. It needs to be sticky, tangy, and slightly sweet to balance the spicy topping.
• Nori Sheets – These seaweed sheets hold everything together and add a subtle briny flavor.
• Avocado – Adds richness and a buttery contrast to the spicy, tangy elements.
• Imitation Crab or Cooked Shrimp – The protein base inside the roll; you can also mix both for variety.
• Scallops or Extra Seafood Mix – Used in the volcano topping, baked and blended with spicy mayo.
• Spicy Mayo (Mayo + Sriracha) – This sauce is key for that signature heat and creaminess.
• Unagi Sauce (Eel Sauce) – A sweet, umami glaze that’s drizzled on top before serving.
• Green Onions – For a fresh, crisp finish on top.
• Black Sesame Seeds – Add a nutty crunch and enhance the visual appeal.
• Rice Vinegar, Sugar, Salt – Used to season the sushi rice perfectly.

Each component plays a role—either in structure, flavor, or presentation—to bring the Volcano Roll together in one glorious bite.

Step 1: Cook and Season the Sushi Rice

Rinse 1 cup of sushi rice until the water runs clear. Cook it according to package instructions. While still warm, gently fold in a mixture of 2 tablespoons rice vinegar, 1 tablespoon sugar, and ½ teaspoon salt. Let the rice cool completely before using.

---

Step 2: Prepare the Filling

Slice avocado into thin strips. Shred imitation crab or chop cooked shrimp finely. If you’d like, mix the seafood with a small spoonful of spicy mayo for extra flavor.

---

Step 3: Roll the Sushi

Lay a sheet of nori on a bamboo mat, rough side up. Spread a thin layer of cooled sushi rice over the nori, leaving a 1-inch border at the top. Add avocado and seafood filling in a horizontal line across the center. Roll tightly using the mat, applying gentle pressure to form a firm cylinder.

---

Step 4: Make the Volcano Topping

Combine chopped cooked scallops or shrimp with spicy mayo (about 2 tablespoons mayo and 1 teaspoon sriracha, adjust to taste). Spoon the mixture over the top of each sliced roll.

---

Step 5: Broil the Topping

Place the rolls on a foil-lined baking tray. Broil for 2–3 minutes until the topping begins to bubble and brown slightly. Watch closely to avoid burning.

---

Step 6: Garnish and Serve

Drizzle unagi sauce over the broiled rolls. Sprinkle green onions and sesame seeds on top. Serve immediately while warm and melty.

---

How Long to Cook the Volcano Roll

While the roll itself doesn’t require traditional cooking, the topping is broiled to create that signature molten finish. Once assembled, the volcano topping should be broiled for 2 to 3 minutes—just enough for it to bubble and slightly char. The rest of the prep, like cooking rice or assembling the rolls, takes about 30–40 minutes total depending on your pace.

Tips for Perfect Volcano Roll

• Use plastic wrap on your sushi mat to keep the rice from sticking and make rolling easier.
• Wet your hands before handling sushi rice—it’s sticky!
• Don’t overfill the roll, or it will burst when you try to close it.
• Chill the finished roll before slicing to get cleaner cuts.
• Broil briefly and watch carefully—the spicy mayo topping can go from golden to burnt in seconds.
• Use a sharp, wet knife for slicing rolls cleanly without smushing the rice.
• Balance the spice in your mayo—start mild and add more sriracha to taste.

---

Watch Out for These Mistakes While Cooking

• Skipping the rice seasoning – Without the vinegar mix, your sushi rice will taste flat.
• Using too much filling – Overloading makes the roll hard to seal and prone to breaking.
• Rolling too loosely – A loose roll falls apart when cut or topped. Use firm, even pressure.
• Using the wrong type of seafood – Raw fish isn’t ideal here; go with cooked or imitation for best texture and safety.
• Leaving the broiler unattended – That spicy mayo topping can burn quickly if you’re not watching closely.
• Cutting with a dull knife – It’ll crush your roll. Always use a sharp, wet blade for neat slices.

Storage Instructions

Volcano Rolls are best enjoyed fresh, especially because of the broiled topping. However, if you have leftovers, store them in an airtight container in the fridge for up to 24 hours. To reheat, remove any delicate garnishes and place the rolls under the broiler for a minute or two—just enough to warm the topping again. Avoid microwaving, as it will make the rice rubbery and the topping greasy.

If you’re prepping ahead, you can roll the sushi and store it uncut, covered in plastic wrap. Just add the volcano topping and broil right before serving.

Frequently Asked Questions

What kind of seafood can I use for the volcano topping?

You can use chopped cooked scallops, shrimp, imitation crab, or a combination of all three. Just make sure it’s cooked before mixing with the spicy mayo.

---

Can I make Volcano Rolls without a sushi mat?

Yes! You can use plastic wrap and a clean kitchen towel to roll, but a bamboo sushi mat gives the best results in terms of shape and tightness.

---

Is it safe to eat the topping without baking it?

The topping should always be broiled to ensure it’s hot and slightly caramelized. Even if the seafood is cooked, broiling enhances flavor and texture.

---

Can I make it vegetarian?

Absolutely. Replace seafood with avocado, cucumber, or cooked tofu and top with spicy vegan mayo and broiled mushrooms or vegan crab alternatives.

---

How spicy is a Volcano Roll?

Moderately spicy. You control the heat through the amount of sriracha in your spicy mayo. Start small and adjust to taste.

---

Can I use regular rice instead of sushi rice?

No, regular rice won’t be sticky enough to hold the roll together. Sushi rice is specially prepared to stay cohesive and flavorful.

---

How long do they keep in the fridge?

They can be stored up to 24 hours, but they’re best eaten the day they’re made. The topping tends to lose texture after refrigeration.

---

Can I freeze Volcano Rolls?

Not recommended. Freezing will ruin the texture of the rice and avocado, and the topping won’t reheat well.

---

With creamy, spicy seafood piled high on neatly rolled rice and avocado, they’re as fun to make as they are to eat. Whether you’re hosting sushi night or just want to treat yourself, this roll brings restaurant-level flair straight to your home kitchen.
