Rice and Seasoning
- 1 1/2 cups uncooked white sushi rice (rinsed well)
- 2 1/4 cups water (or follow instructions on rice cooker)
- 1 tablespoon rice vinegar
- 1 teaspoon sea salt
- Optional: 1 tbsp white sugar
Sweet Potato Coating
- 1 large sweet potato
- 2 eggs (see notes for vegan option)
- 1/2 cup rice flour (brown or white is fine)
- 3/4 cup plain gluten free breadcrumbs or regular breadcrumbs
- 1/2 teaspoon salt
- 1/2 teaspoon garlic powder
Fillings and Dressing
- 1 avocado
- 1 small cucumber (sliced into thin long strips)
- 1/2 cup mayo or tahini
- 2–3 tablespoons hot sauce (or to taste)
- 1/4 teaspoon salt
- Water to thin as needed (usually just if using tahini, not needed for mayo)
Additional
- Nori sheets
- Sushi rolling mat
- Cook Rice: Cook the sushi rice according to package instructions using a rice cooker or stovetop method, ensuring the rice is tender and sticky.
- Add Vinegar and Seasoning: When the rice is done, stir in the rice vinegar, sea salt, and optional white sugar if you desire a slightly sweet flavor. Mix gently and let the rice cool slightly.
- Preheat Oven: Preheat your oven to 400°F (200°C) to prepare for baking the sweet potato slices.
- Prepare Sweet Potato: Wash and peel the sweet potato, then chop into roughly 2-inch long slices about 1/2 inch thick.
- Prepare Coatings: Whisk the eggs in a medium bowl. In a separate bowl, whisk together rice flour, salt, and garlic powder. Place the breadcrumbs in a third bowl.
- Coat Sweet Potato: Create an assembly line for dipping: first dip each sweet potato slice into the egg, then coat with the flour mixture, and finally dip into the breadcrumbs. Repeat the process if you want a thicker coating. Place coated slices on a baking tray lined with parchment paper, spacing them slightly apart for crispiness.
- Bake Sweet Potato: Bake for 25-30 minutes or until the sweet potatoes are lightly browned and crispy on the outside. For extra crispiness, optionally pan-fry the baked slices in hot oil for about 1 minute per side until golden.
- Assemble Sushi: Place a nori sheet on a sushi rolling mat. Spread a layer of sushi rice on the bottom two-thirds of the nori, leaving about 2 inches clear at the top. Press the rice gently to ensure it sticks; wetting your fingers helps prevent sticking.
- Add Fillings: Layer the baked sweet potato slices, cucumber strips, and avocado slices neatly on the rice-covered half of the nori sheet.
- Roll Sushi: Using the bamboo mat, carefully fold the sushi roll up and over the fillings, rolling tightly until only about 1 inch of nori remains. Moisten the edge with water to seal the roll securely.
- Repeat Rolls: Repeat the rolling process until all rice and fillings are used, making multiple sushi rolls.
- Prepare Dressing: In a small bowl, whisk together mayo or tahini with hot sauce and salt. Add water a little at a time if using tahini to achieve desired sauce consistency.
- Serve: Slice the sushi rolls into bite-sized pieces, drizzle with the prepared spicy dressing, and enjoy immediately.
Notes
- For a vegan option, substitute the eggs with a flax egg (1 tbsp ground flaxseed mixed with 3 tbsp water) or aquafaba.
- If you prefer, you can fry the sweet potato slices after baking for extra crispiness.
- Wet your hands or fingers when handling sushi rice to avoid sticking.
- Sushi rice is best used fresh but can be stored covered at room temperature for a short time.
- You can adjust the heat of the dressing by varying the amount of hot sauce used.
