What is Yaki Imo Tempura?
Yaki Imo Tempura brings together two beloved Japanese culinary traditions. First, there’s “yaki imo,” which refers to roasted sweet potatoes that vendors traditionally sell from trucks during colder months in Japan. Then, we have “tempura,” the famous Japanese cooking technique that involves coating ingredients in a light batter and deep-frying them to crispy perfection. Furthermore, when these concepts merge, we get a delightful contrast of textures and flavors – the creamy, caramelized interior of roasted sweet potatoes wrapped in a delicate, crispy tempura shell.

- 1 tablespoon grated daikon radish (optional)
- 1 teaspoon finely chopped green onion

Step-by-Step Instructions
Preparing the Yaki Imo
- First, preheat your oven to 400°F (200°C).
- Meanwhile, wash the sweet potatoes thoroughly and pat them dry.
- Next, poke several holes in the potatoes using a fork to allow steam to escape.
- After that, rub them lightly with vegetable oil and sprinkle with a pinch of salt.
- Subsequently, place the sweet potatoes on a baking sheet lined with foil.
- Roast for approximately 20 minutes, or until they’re partially cooked but still firm enough to slice.
- Then, remove from the oven and let them cool slightly.
- Once cooled, slice the sweet potatoes into rounds about ½-inch thick.

Making the Tempura Batter
- In a medium bowl, combine the flour, cornstarch, and salt.
- In a separate small bowl, lightly beat the cold egg.
- Then, add the ice-cold water to the beaten egg and mix briefly.
- Next, pour the egg mixture into the flour mixture.
- Using chopsticks or a fork, stir the batter gently with a few swift strokes.
- Therefore, leave the batter slightly lumpy – this is the key to light, crispy tempura!

Frying the Yaki Imo Tempura
- Heat the vegetable oil in a deep pot or wok to 350°F (175°C).
- Working in small batches, dip the sweet potato slices into the tempura batter.
- Subsequently, carefully drop the battered slices into the hot oil.
- Fry for about 2-3 minutes, or until the batter turns golden and crisp.
- After that, use a slotted spoon to transfer the tempura to a wire rack or paper towel-lined plate.
- Continue the process with the remaining sweet potato slices.

Serving Your Yaki Imo Tempura
- Arrange your freshly fried Yaki Imo Tempura on a serving plate.
- If desired, serve with tempura dipping sauce garnished with grated daikon and green onion.
- Alternatively, try serving with a light drizzle of honey or maple syrup for a sweeter take.
- Finally, enjoy while still hot and crispy!

Tips for Perfect Yaki Imo Tempura
To ensure your Yaki Imo Tempura turns out perfectly every time, consider these helpful tips:
- Keep everything cold: The key to crispy tempura is using cold ingredients for the batter. Furthermore, you can even chill your mixing bowl beforehand.
- Don’t overmix: Mix the batter minimally until ingredients are just combined. Consequently, those lumps create air pockets that make your tempura light and crispy.
- Maintain oil temperature: Use a cooking thermometer to keep the oil at a consistent temperature. If the oil is too cool, the tempura will absorb too much oil. Conversely, if it’s too hot, the outside will burn before the inside cooks.
- Fry in small batches: Overcrowding the pot will lower the oil temperature and result in soggy tempura.
- Prep ahead: You can roast the sweet potatoes earlier in the day and refrigerate them until you’re ready to make the tempura.
Variations to Try
Once you’ve mastered the basic Yaki Imo Tempura recipe, you might want to experiment with these delicious variations:
- Spicy version: Add a pinch of cayenne pepper or shichimi togarashi to the tempura batter for a spicy kick that contrasts beautifully with the sweet potatoes.
- Herb-infused: Mix finely chopped herbs like shiso, cilantro, or thyme into your batter for an aromatic twist.
- Sweet coating: After frying, dust your Yaki Imo Tempura with a mixture of cinnamon and sugar for a dessert-like treat.
- Mixed root vegetable tempura: Combine your yaki imo with other root vegetables like kabocha squash, carrots, or regular potatoes for a colorful tempura platter.
Pairing Suggestions
This Yaki Imo Tempura recipe works wonderfully as part of a larger Japanese-inspired meal. Consider serving it alongside:
- A simple miso soup
- Steamed rice
- Pickled vegetables (tsukemono)

Additionally, it pairs beautifully with cold beer, sake, or even a crisp white wine like Sauvignon Blanc or Riesling.
Health Benefits
Although Yaki Imo Tempura is a fried dish, it does offer some nutritional benefits! Sweet potatoes are packed with vitamins A and C, fiber, and antioxidants. Moreover, using a proper tempura technique means less oil absorption than other frying methods. As a result, you can enjoy this treat occasionally as part of a balanced diet.
