Vegetable Tempura Roll Recipe with Step-by-Step Instructions

Vegetable tempura rolls merge two of the most popular types of Japanese cuisine, tempura and sushi, into a meal that’s hard to beat. The savory flavors of the vegetable tempura complement the salty vinegar flavor of the sushi rice and nori sheet. In addition, as everything in this roll is cooked, it’s great for those new to sushi or hesitant to eat raw fish.

What is a Vegetable Tempura Roll?

A vegetable tempura roll contains a variety of vegetables coated in a tempura batter and deep fried. The vegetable tempura is then wrapped in a seaweed wrapper (nori sheet) that is coated with sushi rice. I like to serve it with a ramekin of my homemade tempura dipping sauce (tentsuyu). However, you can also serve with soy sauce, wasabi, and pickled ginger.

Typically, I prepare vegetable tempura rolls as an uramaki roll, also known as an inside-out roll where the rice is on the outside of the nori sheet and the fillings are on the inside. However, I’ve seen this prepared as a maki roll as well (rice on the inside of the nori sheet with the fillings).

How to Control the Thickness of Your Roll

You can control how thick your sushi rolls are by how much of the nori sheet you use.  I prefer to use an entire nori sheet when preparing vegetable tempura rolls as I like to load it with fillings. This makes for thicker rolls.

You can make your sushi rolls thinner by using 3/4 or half of the nori sheet. However, you would need to adjust your fillings accordingly.

How to Make Vegetable Tempura Rolls

While making vegetable tempura rolls is a bit of a process, the end product is worth the effort. Below we will walk you through how to make these savory rolls step-by-step:

Heat the oil

1. Heat enough vegetable oil to completely submerge the vegetables on medium heat. The oil should be heated to 350 degrees.

Heat oil on medium heat to 350 degrees.

Cook the Sushi Rice

1. Rinse 1 1/3 cups of sushi rice by placing it in a colander and running water through it until the water is clear.

Rinse the sushi rice in water prior to cooking

2. After the rice is rinsed, add it to a sauce pan with 1 1/2 cups of water. Check your sushi rice package to see the exact amount of water to be added as it can vary from depending on the brand you use.

3. Bring the water to a boil and then reduce the heat to low. Cover and let the rice simmer for 20 to 30 minutes, or until the water is absorbed and the rice is soft.

Bring sushi rice to a boil and let simmer for approximately 20 minutes or until fully cooked.

4. Remove the rice and place it into a bowl or dish and let cool. I would line the dish with parchment paper prior to adding the rice to avoid sticking.

Add sushi rice to a bowl or casserole dish lined with parchment paper. This prevents the rice from sticking to the bowl or dish.

5. Mix 1/4 cup of sushi vinegar into your rice. Stir until it has absorbed into the rice. Once cooled and fully absorbed, your rice is ready to roll!

Mix sushi vinegar into the sushi rice using a chopping motion until the vinegar until fully absorbed into sushi rice.

Assemble the Ingredients and Cut the Vegetables

1. Cut the ends off of the asparagus stalks and discard.

Cut the ends from the asparagus prior to dipping in tempura batter.

2. Peel the sweet potato and cut into thin strips that are as long as the nori sheet is wide.

Peel and cut sweet potato into strips that are as long as your nori sheet is wide.

3. Cut the eggplant into thin slices and cut the slices in half so they will better fit into the sushi roll.

Cut the eggplant into slices.  After that, cut the slices in half so they will better fit into the vegetable tempura roll.

4. Once cut, dredge the vegetables in flour, and place on plate until needed. This helps the tempura batter to better stick to the vegetables.

Make Tempura Batter

1. Assemble the ingredients and chill the water. You may need to add ice if you don’t have access to very cold water. However, make sure to remove the ice cubes before combining with egg. I usually strain the ice cubes out of the water as I add to the egg.

2. Crack the egg into a small bowl and beat until the yolk and white are combined.

Add egg to the mixing bowl to make tempura batter.

3. Add cold water to the egg and mix well.

Strain ice water into the mixing bowl.

4. Add one cup of sifted flour into the egg and water mixture. You can also sift the flour directly into the mixing bowl.

Sift flour into the mixing bowl.

5. Lightly mix the flour into batter, making sure not to over stir. The batter should be combined but a little lumpy.

Mix flour into tempura batter making sure not to over-stir.

Coat the Vegetables into Batter and Cook in Oil

1. Each of the vegetables have different cooking times so make sure you cook each type separately. Add the sweet potato strips to the batter and toss until coated. Then add to the hot oil and cook for three minutes.

Add sweet potato to the oil and cook for three minutes.

3. After three minutes, remove from oil and add to a paper towel-lined plate to absorb the oil.

Remove sweet potato strips from the oil after cooking for around 3 minutes.

4. Add the asparagus to the batter and toss until coated. Then add to the hot oil and cook for two minutes.

Add asparagus to the oil and cook for around two minutes.

5. After two minutes, remove from oil and add to a paper towel-lined plate to absorb the oil.

Remove asparagus tempura from the oil after cooking for two minutes.

6. Add the eggplant slices to the batter and toss until coated. Then add to the hot oil and cook for one and a half minutes.

Dip the eggplant in tempura batter and cook in for around a minute and a half.

7. After a minute and a half, remove from oil and add to a paper towel-lined plate to absorb the oil.

After around a minute and a half, remove the eggplant tempura and add to a paper towel lined plate.

Assemble the Sushi Roll

1. Cover your bamboo sushi mat with plastic wrap. This will help keep the rice from sticking to it.

2. Next, place the nori sheet onto the plastic wrap with the shiny side facing down. Then press around a cup of sushi rice onto the nori sheet in an even layer. Tip: Combine a bowl of water and a splash of rice vinegar and use to wet your hands prior to handling the sushi rice. This will prevent the rice from sticking to your hands.

Spread rice onto the nori sheet.

3. Gently flip the nori sheet over so the rice is facing down. You will add the filling directly to the nori sheet with the rice on the outside.

Flip the nori sheet as I like to prepare the vegetable tempura roll as an uramaki roll.

4. Add the vegetable tempura to the nori sheet. I usually add one to two sweet potato strips, two to four stalks of asparagus, and two halves of the eggplant tempura depending on the size of the vegetables and how well everything fits.

Add vegetables to the vegetable tempura roll.

5. Use the bamboo sushi mat to fold your roll until it’s completely enclosed. Once the rice is making contact with the nori sheet, pull back the sushi mat so it doesn’t get caught in the roll. Still using the sushi mat as your guide, finish rolling until the roll is completely wrapped. Then wrap the sushi mat around the roll and gently press, tightening the roll together. Keep in mind that rolling sushi is an art that may take some practice so don’t get frustrated if it doesn’t look perfect your first time. It will get easier the more you do it.

Roll the vegetable tempura roll.

6. Using a sharp knife, cut the roll into 8 pieces. I do this by first cutting the roll in half. Then I cut each half in half followed by cutting each fourth in half. Tip: Be sure to clean and wet the edge of your knife before cutting each roll.

Cut the sushi roll into eight pieces.

7. Serve with tempura dipping sauce (tentsuyu). You can also serve with soy sauce, wasabi, and pickled ginger.

Frequently Asked Questions

Are vegetable tempura rolls gluten-free?

If ordered from a restaurant, vegetable tempura rolls will almost always contain gluten as flour is a main component of the tempura batter. However, if you make tempura yourself you can use a one-to-one gluten free substitute in your batter. This may make the batter a little more dense but the final product still tastes amazing.

Are vegetable tempura rolls eaten in Japan?

Yes, the tempura style of cooking was introduced to Japan by the Portuguese back to the 1600’s and has been popular ever since. While most sushi restaurants focus on the nigiri style of sushi, vegetable tempura rolls are also eaten in Japan.
