Origin and Inspiration
Daigaku Imo, which translates to "university potato," has its roots in Japanese history, tracing back to the late 19th century. Originally popular among university students in Tokyo, this dish became an icon of street food culture. Traditionally prepared by frying or roasting slices of sweet potatoes before glazing them with a rich syrup, it exemplifies the Japanese knack for elevating simple ingredients.
Globally, the concept of caramelized root vegetables manifests in various cultures—think of American candied yams or Indian shakkar pare—but what sets Daigaku Imo apart is its unique crust and the crunch of sesame seeds against the soft, sweet interior. The keto adaptation swaps traditional sweet potatoes for a blend of lower-carb vegetables, ensuring that you don’t miss out on flavor. Imagine biting into a piece that’s sweet and savory, with a satisfying crunch, all while sticking to your dietary preferences—that’s the magic of the keto sweet potato!

Ingredients (2 Servings)
Shared Ingredients:
- 2 medium sweet potatoes
- 2 tablespoons sesame seeds
- 2 tablespoons coconut sugar or erythritol (for keto version)
- 2 tablespoons water
Traditional Version:
- 2 tablespoons vegetable oil
Keto Version:
- 2 tablespoons unsweetened coconut oil
Instructions
1. Prepare the Sweet Potatoes:
Peel the sweet potatoes and slice them into rounds, roughly ½ inch thick. Each piece should feel firm in your hands, reminiscent of nature’s candy ready to be transformed.
2. Cooking Method:
Traditional Version:
- Heat the vegetable oil in a frying pan over medium heat.
- Carefully add the sliced sweet potatoes to the pan; you should hear a gentle sizzle as they hit the hot oil. Fry until golden brown on both sides, about 4-5 minutes per side.
Keto Version:
- For the keto version, use unsweetened coconut oil in the frying pan and follow the same frying method. Ensure that the coconut oil melts luxuriously, enveloping the sweet potato slices as they cook.
3. Caramelize the Sweet Potatoes:
- Once the potatoes are cooked, reduce the heat and add coconut sugar or erythritol mixed with water into the pan. Stir gently, allowing the sweet potatoes to get coated in the glossy syrup while it caramelizes. This process will take about 2-3 minutes until the syrup thickens into a delightful glaze.
4. Shaping/Final Assembly:
- Sprinkle the sesame seeds across the caramelized potatoes, letting them gently fall like edible confetti, adding both crunch and flavor. The golden hue of the caramel will glisten as you transfer them to a serving dish.
5. Serve Warm:
- Place the beautifully caramelized sweet potato slices onto a plate or serve with toothpicks for a delightful snack. The presentation should beckon you to dive in immediately, as the aromas waft tantalizingly around you.
What Does It Pair Well With?
- Traditional Pairings: Enjoy Daigaku Imo with a cup of matcha tea or warm sake—expressing a delightful balance between sweet and savory while allowing the dish’s flavors to shine.
- Keto-Friendly Pairings: Pair your keto sweet potatoes with low-carb yogurt or a refreshing cucumber salad, enhancing the sweetness with a crunchy, cooling touch.
What is the Shelf Life?
Daigaku Imo is best served fresh to appreciate its caramelized texture. However, it can be stored in an airtight container for up to 3 days in the refrigerator. For those who wish to freeze it, place it in a freezer-safe bag, where it will keep for about a month. Reheat in an oven or air fryer, reviving its crispy exterior.
Alternative Cooking Methods
- Oven: Preheat your oven to 400°F (200°C). Arrange sliced sweet potatoes on a baking sheet, drizzled with oil and sugar mix. Roast for 25-30 minutes until tender and chunky caramelized edges form.
- Air Fryer: For a quick and less oily version, air fry the sweet potato slices at 370°F (185°C) for about 20 minutes, tossing halfway through.
