Sweet Potato Sushi

This sweet potato sushi recipe works because it balances opposites. Shatter-crisp tempura, soft sushi rice, creamy avocado, and briny nori come together to make a roll that feels bold, fresh, and designed for sushi night at home.

This sweet potato sushi roll is like the avocado toast of rolls: obvious once you taste it, but still kind of brilliant. Crisp, golden sweet potato tempura meets cool avocado and seasoned rice, wrapped snug in nori and brushed with a glossy teriyaki glaze. The first bite ticks off all the vegan sushi boxes: crunchy, tender, salty-sweet, and a clean briny hit from the nori.

What seals the deal? The contrast. You have a crackly coating paired with soft, sticky rice, with just enough of a messy factor to prove that perfection isn’t the point here. Get ready to transform a humble root vegetable into the star of your stay-at-home sushi night.

Why You’ll Love This Sweet Potato Sushi Roll

This is the roll that makes sushi night in feel just as good as going out. The sound of tempura crackling in hot oil, the smell of toasted nori, and the shine of teriyaki glaze on a fresh slice—this is sushi that is as much fun to make as it is to eat. And the first bite? Crisp, creamy, salty-sweet, briny: this is the balance that makes this sweet potato sushi roll a keeper. Here’s why:

  • Big Flavor, Minimal Fuss: A handful of core ingredients—sweet potato, avocado, nori, and sushi rice—are enough to deliver serious payoff. Assembly is simple, but the result tastes like more than the sum of its parts.
  • Crisp Meets Creamy: Hot tempura brings crunch, avocado adds fat and softness, rice gives chew, and the teriyaki glaze adds a layer of seasoning that clings to the top. Each element is doing a specific job, and together they balance the roll.
  • Tempura Done Right: Ice-cold batter and oil at a steady 350°F gives you a crisp shell that stays light instead of greasy. The sweet potato inside turns tender and rich, setting up the contrast that makes this sweet potato tempura sushi work.
  • Looks the Part: Sweet potato batons stack neatly, anchoring the center for tighter spirals and cleaner cuts. Run your knife blade under scalding hot water, wipe it down with a clean towel, and your roll will slice like butter.
  • A Roll Worth Repeating: The teriyaki glaze can be made ahead, and the rice cooker does the heavy lifting. Once you’ve rolled it, the process gets easier and more fun.

Key Ingredients

At its core, this roll is simple: crisp sweet potato tempura, creamy avocado, seasoned rice, and a slick of teriyaki glaze wrapped in nori. Each piece does something specific—bringing crunch, fat, tang, or brine—so the roll feels balanced and complete. Here’s what you’ll need:

An unpeeled sweet potato against a dark background.
  • Sweet Potato: The star of the roll. Once cut and fried in tempura batter, the outside turns golden and crisp while the inside softens into a sweet, tender core. It’s the flavor anchor and the textural payoff that makes this sweet potato sushi roll work.
  • Tempura Batter: Light, lacy, and shatter-crisp when done right. The secret is ice-cold sparkling water and a quick stir—don’t overmix. This creates the signature crackle that separates sweet potato tempura sushi from plain roasted versions.
  • Sushi Rice: Sticky, seasoned, and slightly sweet. Rice vinegar, sugar, and salt balance the starch, giving each bite a subtle tang. Spread it thinly across nori for rolls that hold tight without falling apart.
  • Nori Sheets: Toasted seaweed sheets do more than just wrap—they add briny depth and a clean ocean note that cuts through the richness of tempura and avocado.
  • Avocado: Cool, creamy, and buttery. It softens the crunch of tempura, adding richness and balance while making each slice feel indulgent.
  • Teriyaki Glaze: This is your signature twist. A glossy drizzle of homemade teriyaki sets this roll apart from the spicy mayo crowd, adding sweet-savory depth that clings to the top and makes every slice glisten.
  • Sesame Seeds: Black or white, they add a nutty crunch and visual contrast. Scattered over the rice, they create tiny bursts of flavor with each bite.

How To Vary These Vegan Sushi Rolls

One of the best things about making this sweet potato sushi at home is how easy it is to swap in different fillings or sauces. Once you’ve nailed the basics—rice, nori, rolling—the inside is yours to play with. Here are a few ideas to keep things fresh:

More Ideas For Vegetable Tempura

  • Broccoli: Lightly battered florets fry up tender-crisp and bring a subtle earthy flavor.
  • Kabocha Squash: Sweet and dense, with a flavor similar to chestnut. Great for fall rolls.
  • Oyster Mushrooms: Meaty, savory, and perfectly suited for tempura’s light crunch.

Sauce Swaps

  • Spicy Mayo: The classic pairing. Mix vegan mayo with sriracha for a creamy, fiery kick.
  • Ponzu Dipping Sauce: A citrusy soy-based sauce that brightens rich fillings.

Fresh Add-Ins

  • Cucumber Batons: Add cool crunch and balance out the fried elements.
  • Pickled Daikon or Other Fermented Vegetables: Brings a tangy snap that cuts through creamy avocado.
  • Shredded Carrots: Sweet and crunchy, and they tuck neatly into rolls.
  • Don’t want to deep-fry? Roast or air fry the sweet potato instead. You’ll have something a little less dramatic, but still delivers a pop of color and flavor.

How To Make

Making sweet potato sushi rolls is less about fancy technique and more about setup. The rice, the tempura, the rolling—each part is simple once you know what matters. Keep your batter ice-cold, your oil steady at 350°F, and your rolling mat skills tight. You’ll be slicing neat, glossy rolls in no time.

  • Step 1: Make the Teriyaki Glaze – Whisk together brown sugar, mirin, sake (if using), and soy sauce. In a saucepan, sauté ginger in sesame oil for a minute, then add the mixture. Simmer until thickened and glossy—about 30 minutes. Keep at room temperature until ready to brush over your rolls. Feel free to make beforehand and chill, but just allow it to warm up slightly before serving.
  • Step 2: Rinse and Cook the Sushi Rice – Rinse the rice several times in a bowl until the water runs clear. In a rice cooker, cook the sushi rice according to the manufacturer’s instructions. While warm, season with rice vinegar, sugar, and salt. Spread it out to cool before rolling—it should be sticky, but not hot. Pro Tip: Rinsing rice removes excess starch so the grains stay separate yet sticky—essential for rolls that hold together.
  • Step 3: Fry the Sweet Potato Tempura – Heat 2–3 inches of oil in a heavy pot to 350°F. Mix chilled JUST Egg with sparkling water, then add flour and salt. Stir gently with chopsticks, and do not overmix. A few lumps are okay. Dip the sweet potato batons, fry until golden and crisp, and drain on paper towels. Sprinkle lightly with salt while still hot.
  • Step 4: Assemble the Roll – Wrap a sushi mat in plastic, then place a sheet of nori shiny side down. Spread rice evenly over the sheet, leaving 1 inch uncovered at the top. Sprinkle with sesame seeds. Along the bottom edge, layer sweet potato tempura, avocado slices, and a swipe of vegan mayo (optional). Pro Tip: Keep a small bowl of water nearby to dip your fingers—it prevents rice from sticking and keeps the spread even.

  • Step 5: Roll and Slice – Use the mat to roll tightly away from you, sealing the edge with a little water or rice. Slice into 8 pieces with a very sharp knife that’s been run under scalding hot water, wiping the blade between cuts. Brush the tops with teriyaki glaze and serve with wasabi and pickled ginger.

How To Serve

You’ve rolled your sweet potato sushi, brushed it with glaze, and sliced it clean—now it’s time to plate. Whether you’re building a full sushi night spread or keeping things simple, here are a few ways to serve and pair your rolls.

  • The Essentials: Wasabi, Soy Sauce & Pickled Ginger: These classic condiments earn their spot every time. Wasabi brings sharp heat, soy sauce (or tamari for gluten-free) adds umami depth, and pickled ginger resets your palate between bites.
  • Miso Soup on the Side: A steaming bowl of miso soup makes sushi night feel complete. Light and savory, it’s especially good with seared tofu cubes, wakame seaweed, and a sprinkle of scallions.
  • Seaweed Salad for Contrast: That sesame-scented wakame salad you see at sushi bars is the perfect counterpoint here: cool, crunchy, and slightly sweet against the warm tempura.
  • As Part of A Sushi Night Spread: Serve these with our vegan California roll, Dynamite sushi, asparagus rolls, and sushi with lobster mushrooms. For more ideas, check out our vegan sushi recipe roundup!
  • Mix and match sweet potato sushi rolls with other veggie fillings for a colorful spread. Check out more of our vegan sushi recipes for more ideas and inspiration. They are all perfect for a party or just a quiet sushi night in with friends.
  • Edamame as a Snackable Side: Steamed edamame tossed with flaky sea salt is a quick, protein-packed side. For more kick, add garlic, chili flakes, and a dash of sesame oil.

FAQs

What is in a sweet potato sushi roll?

A sweet potato sushi roll typically includes tempura-fried sweet potato, avocado, seasoned sushi rice, and nori. Some versions add sesame seeds, vegan mayo, or a drizzle of sauce like teriyaki or spicy mayo.

Is there raw fish in sweet potato sushi?

No—sweet potato sushi rolls are completely plant-based. Instead of raw fish, the filling is made with tempura sweet potato and other vegetables, making it a popular vegan sushi option.

Description

This sweet potato sushi roll is proof that sushi night at home can outshine takeout. Crisp sweet potato tempura, buttery avocado, and seasoned rice get wrapped in nori, then brushed with a glossy teriyaki glaze. Every bite delivers crunch, cream, and briny depth—the kind of balance that makes this roll one you’ll keep coming back to.


Ingredients

For the teriyaki glaze

  • 1 cup brown sugar
  • 1 cup mirin
  • 1/8 cup sake (optional—omit for a thicker glaze once cooled)
  • 1/2 cup soy sauce
  • 1 tablespoon toasted sesame oil
  • 1 tablespoon minced ginger

For the sushi rice

  • 1 cup sushi rice
  • 1 cup water
  • 1 teaspoon rice vinegar
  • 1 teaspoon sugar
  • 1/2 teaspoon salt

For the sweet potato tempura

  • Neutral oil (like grapeseed, canola, or vegetable) for frying
  • 1 medium sweet potato, peeled and cut into batons (about the size of your index finger)
  • 1 tablespoon JUST Egg, chilled
  • 1 1/4 cups ice-cold sparkling water (plus more if batter needs thinning)
  • 1 cup all-purpose flour, chilled
  • 1 teaspoon salt

To assemble and finish

  • 4 toasted nori sheets
  • 4 tablespoons black and/or white sesame seeds
  • 1 ripe avocado, sliced
  • 24 tablespoons vegan mayo (optional)
  • Wasabi (optional)
  • Pickled ginger (optional)


Instructions

Make the teriyaki glaze

  1. In a bowl, whisk together the brown sugar, mirin, sake (if using), and soy sauce.
  2. Heat sesame oil in a small saucepan over medium heat. Add ginger and sauté for 1 minute.
  3. Pour in the sugar-mirin mixture, whisking to dissolve. Bring just to a boil, then lower heat to maintain a gentle simmer. Cook 30–35 minutes, whisking occasionally, until slightly thickened.
  4. Remove from heat and let cool. The glaze will thicken as it chills; if it sets too firm, loosen with a quick microwave zap.

Cook the sushi rice

  1. Rinse the rice several times until the water runs clear, then cook with 1 cup water in a rice cooker according to the manufacturer’s instructions.
  2. While warm, season with rice vinegar, sugar, and salt. Let cool before rolling.

Fry the sweet potato tempura

  1. Heat 2–3 inches of oil in a heavy pot to 350°F. Test by dipping a dry chopstick—if bubbles form instantly, the oil is ready.
  2. In a bowl, whisk chilled JUST Egg with sparkling water. Add flour and gently stir with chopsticks. Some lumps are fine; don’t overmix.
  3. Working in batches, dip sweet potato batons into batter and lower carefully into oil. Fry until golden and crisp, then transfer to paper towels. Sprinkle lightly with salt while hot.

Assemble the rolls

  1. Wrap a sushi mat in plastic wrap or slide it into a large resealable bag. Place one sheet of nori, shiny side down, on the mat.
  2. Moisten your fingers to keep rice from sticking, then spread 1/4 of the sushi rice evenly over the nori, leaving 1 inch uncovered at the top. Sprinkle with 1 tablespoon sesame seeds.
  3. Along the bottom edge, layer 2–3 tempura sweet potato batons, a few avocado slices, and a swipe of vegan mayo if desired.
  4. Roll tightly away from you, using the mat to shape and seal. Dab the edge with water or a few grains of rice to close.
  5. Slice the roll into 8 pieces with a very sharp knife. I run the blade under scalding water and give it a quick wipe with a towel for a cleaner cut.
  6. Repeat with the remaining ingredients to make 4 rolls. Brush tops with teriyaki glaze and serve with wasabi and pickled ginger.

Notes

  • Storage: Like most sushi rolls, these sweet potato sushi rolls are at their peak the day you make them. Refrigeration changes the rice texture, making it dry and firm. If you must store leftovers, wrap tightly in plastic and refrigerate up to 24 hours. Let come to room temperature before eating.
  • Make ahead: You can prepare the teriyaki glaze a day or two in advance. Assemble and glaze the rolls just before serving for the best flavor and texture.
  • Skip the glaze until serving: Brush the teriyaki glaze on just before slicing and serving. If applied too early, the rolls soften and lose their clean edges.
  • Reheating tempura: Leftover sweet potato tempura can be crisped in a 375°F oven or air fryer for 5–8 minutes. Skip the microwave—it makes the coating soggy.
  • Cold batter, hot oil: For light, crisp tempura, your batter should be ice-cold and your oil steady at 350°F. Don’t mix the batter until your oil is hot and ready to go.
  • Fry in small batches: Overcrowding the pot lowers the oil temperature and leads to greasy tempura. Keep pieces spaced out for even cooking.
  • Skim between batches: Use a fine-mesh skimmer to remove fried bits from the oil. This keeps the oil clean and prevents burnt, bitter flavors from clinging to the next batch.
  • Rolling tip: For the cleanest slices, run your knife under hot water and wipe between cuts. This prevents the rice from sticking and helps keep your rolls tight and even.

  1. This recipe is awesome. Followed it to the T but used regular egg bc not vegan. It was an absolute star. Dinner guests thrilled!

  2. Absolutely stunning! I haven’t had vegan sushi in a while and just the mere title of this recipe has sent my cravings into high alert. I’m curious, do you think the veganegg could be substituted with aquafaba or something along those lines?

    1. Thank you Shannon! I am not sure af would work in here, but if you try with good results, I’d love to know! I also think you could just leave the veganegg out and it would still likely work. Good luck! 🙂
