What is a Sweet Potato Tempura Roll?
A sweet potato tempura roll is a type of makizushi, or rolled sushi, where tempura-fried sweet potato is used as the main filling. The roll typically includes nori (seaweed), seasoned sushi rice, and other fresh fillings like avocado or cucumber. It’s a fantastic option for those looking for a plant-based or vegetarian alternative to traditional sushi rolls that contain fish.
The sweetness of the tempura-fried sweet potato contrasts beautifully with the savory rice and tangy dipping sauces, making it a favorite among vegans and sushi lovers alike. What sets the sweet potato tempura roll apart is its satisfying crunch from the tempura batter and the versatility in additional fillings. You can easily customize the roll with your favorite vegetables or even drizzle it with a bit of sriracha mayo for extra flavor.

- 2 cups sushi rice, cooked and seasoned with rice vinegar, sugar, and salt.
- 4 sheets of nori (seaweed).
- 1 avocado, thinly sliced (optional).

Step-by-Step Guide to Making Sweet Potato Tempura Rolls
Step 1: Prepare the Sushi Rice
Start by cooking 2 cups of sushi rice. Rinse the rice under cold water until the water runs clear to remove excess starch. Once cooked, season the rice with a mixture of 1/4 cup rice vinegar, 1 tablespoon sugar, and 1 teaspoon salt. Gently fold the seasoning into the rice and let it cool to room temperature.
Step 2: Prepare the Sweet Potato Tempura
While the rice is cooling, prepare the tempura batter. In a bowl, whisk together 1 cup of flour, 1 tablespoon of cornstarch, and 1/2 teaspoon of baking soda (optional). Slowly add 1 cup of ice-cold water, stirring gently to avoid over-mixing. The batter should remain slightly lumpy for the crispiest results.
Heat vegetable oil in a deep pan or fryer to 350°F (175°C). Coat the sweet potato strips in the tempura batter and fry them in the hot oil for about 2-3 minutes until golden and crispy. Remove the sweet potatoes and drain them on a wire rack to maintain crispiness.
Step 3: Set Up the Sushi Rolling Station
Place a bamboo sushi mat on a flat surface and cover it with plastic wrap. Lay a sheet of nori on the plastic wrap. Wet your hands to prevent the rice from sticking and spread a thin layer of sushi rice evenly over the nori, leaving about 1 inch of space at the top.
Step 4: Add Fillings and Roll the Sushi
In the center of the rice, place a few strips of tempura-fried sweet potato, along with optional fillings like avocado or cucumber. Using the bamboo mat, carefully roll the sushi, applying gentle pressure to keep the roll tight. Seal the roll by lightly wetting the edge of the nori with water.
Step 5: Slice the Roll
Use a sharp knife dipped in water to slice the roll into 6-8 pieces. A sharp knife is crucial to ensure clean cuts and avoid crushing the roll.
Step 6: Serve and Garnish
Serve your sweet potato tempura rolls on a plate. Garnish with sesame seeds or drizzle with sriracha mayo for an extra burst of flavor. Serve with soy sauce, pickled ginger, and wasabi on the side.
Popular Variations of Sweet Potato Tempura Rolls
Once you’ve mastered the basic sweet potato tempura roll, there are plenty of ways to mix up the recipe with different fillings and toppings. Here are a few popular variations:
- Avocado and Sweet Potato Roll: Adding creamy avocado creates a perfect balance with the crunchy tempura.
- Spicy Sweet Potato Roll: For those who like a bit of heat, drizzle the roll with spicy mayo or sriracha for a kick.
- Cucumber and Sweet Potato Roll: Adding fresh cucumber to the roll gives it a refreshing crunch that complements the sweetness of the potato.
- Sweet Potato and Cream Cheese Roll: Vegan cream cheese adds a smooth, rich texture to the roll.
Tips for Perfecting Sweet Potato Tempura Rolls
Making perfect sweet potato tempura rolls at home requires a bit of practice, but here are some tips to help you get it right every time:
- Cold Tempura Batter: The key to light, crispy tempura is using ice-cold water in the batter. This prevents the coating from becoming too thick and heavy.
- Don’t Over-Mix the Batter: A slightly lumpy batter yields the best results. Over-mixing can result in a dense, soggy coating.
- Rolling the Sushi: Make sure to roll the sushi tightly using the bamboo mat to prevent the roll from falling apart when slicing.
- Crispiness: After frying the sweet potato, let it drain on a wire rack rather than paper towels to keep the tempura crispy.
How to Serve and Store Sweet Potato Tempura Rolls
Serving
Sushi is best enjoyed fresh, and sweet potato tempura rolls are no exception. Serve them immediately with soy sauce, pickled ginger, and wasabi on the side. You can also top your sushi rolls with a drizzle of eel sauce or spicy mayo for extra flavor.
Storing Leftovers
If you have leftover rolls, store them in an airtight container and refrigerate for up to one day. Keep in mind that the tempura will lose some of its crispiness over time, so it’s best to eat them fresh. You can try lightly reheating the tempura pieces in the oven to restore some crunch.
FAQs About Sweet Potato Tempura Rolls
What is the best rice for sushi rolls?
Use short-grain sushi rice for the best results. It has the perfect sticky texture needed to hold the rolls together.
Can I make sweet potato tempura rolls gluten-free?
Yes, you can make a gluten-free version by using gluten-free flour or tempura mix and ensuring the soy sauce is also gluten-free.
Can I bake the sweet potatoes instead of frying them?
Yes, if you prefer a healthier version, you can bake the sweet potatoes at 400°F (200°C) for about 20 minutes until tender and slightly crispy.
How do I prevent the sushi rolls from falling apart?
Be sure to roll the sushi tightly using the bamboo mat and apply light pressure while rolling. This ensures that the ingredients stay in place when you cut the roll.
Can I substitute regular potatoes for sweet potatoes?
Yes, you can use regular potatoes, but the flavor will be slightly different. Sweet potatoes provide a nice contrast with their natural sweetness.
Common Mistakes to Avoid When Making Sweet Potato Tempura Rolls
- Overcooking the Sweet Potato: Fry the sweet potato just long enough to achieve a golden, crispy texture. Overcooking will make it soggy and lose its crispiness.
- Not Using Cold Water in Tempura Batter: The water for your tempura batter should be ice-cold to ensure a light, crispy coating. Warm water will result in a heavier, greasier tempura.
- Rolling the Sushi Too Loosely: If the sushi roll is too loose, it will fall apart when sliced. Use the bamboo mat to apply gentle but firm pressure while rolling.
- Using a Dull Knife: A sharp knife is essential for cutting clean, even slices. A dull knife can crush the roll and ruin its presentation.
