The sweet potatoes are the star here—orange-fleshed varieties work best for that perfect chewy texture. Grab a couple from the produce section, or if you're at Trader Joe's, their organic sweet potatoes are a great choice. Peel them first, then slice evenly—about 1/2-inch thick—so they cook through without burning. For extra crispiness, let the slices sit out for 10 minutes before frying (this removes excess moisture). The batter needs to be just right: too thick and they'll be dense; too thin and they won't hold together. King Arthur flour is my go-to for that perfect lightness, but any all-purpose flour works in a pinch.
No sesame oil? Toasted sesame seeds plus a dash of neutral oil still gives that nutty aroma. Short on green onions? Substitute with scallions or even more finely chopped regular onions—just add a pinch of sugar to balance the sharpness. The soy sauce can be swapped for tamari if gluten-free, and if you've got gochujang paste (Korean chili flakes), mix in 1 tsp for a spicy kick. For a richer flavor, add 1 tbsp of vegetable broth powder to the batter. The key to crispy jeon is high heat—use a heavy-bottomed pan or cast iron to avoid soggy bottoms, and don't overcrowd the pan. Work in batches if needed.
Jeon reheat beautifully—just pop them in a 350°F oven for 5-7 minutes until crispy again. Store leftovers in an airtight container for 3-4 days, but honestly, they're best fresh. Freeze extras between parchment paper for up to 2 months. Pro tip: Make the batter ahead and refrigerate it for up to 24 hours—just whisk it again before using. These crispy bites pair perfectly with a simple soy-vinegar dipping sauce (mix 3 tbsp soy sauce, 1 tbsp rice vinegar, and 1 tsp sugar) for the ultimate Korean street-food vibe.

Step-by-step instructions for sweet potato jeon
Here's how to make these crispy Korean pancakes with perfect texture every time.
Prepare the Sweet Potato Slices
Peel the 2 whole medium sweet potatoes and cut them into ½-inch thick slices. I like to use a sharp mandoline for even slices, but a chef's knife works too if you're careful. Arrange the slices on a paper towel-lined plate and sprinkle lightly with the 0.5 teaspoon salt. Let them sit for 10 minutes—this draws out excess moisture so they won't make your batter soggy.
After 10 minutes, pat the slices dry with another paper towel. You want them to be completely dry before moving to the next step. This drying process is crucial for that perfect crispy exterior. If any slices feel damp, give them another quick pat—we're aiming for that satisfying crunch when we fry them later.
Make the Batter
In a large bowl, whisk together the 1 cup all-purpose flour, 0.25 teaspoon black pepper, 0.5 teaspoon garlic powder, and 2 tablespoons soy sauce until combined. The flour should be smooth with no lumps—this ensures a light, crispy coating. In a separate bowl, beat the 2 whole large eggs until just combined.
Pour the beaten eggs into the flour mixture and stir gently until just combined. Add the 0.25 cup thinly sliced green onions and mix lightly—you want them distributed but still visible for that fresh pop of color. The batter should be thick but pourable, like heavy cream. If it's too thick, add 1 tablespoon of the 0.25 cup vegetable broth to loosen it slightly. This batter is the foundation of our crispy exterior and chewy interior.
Assemble the Jeon
Heat 1 tablespoon of the vegetable oil in a 10-inch non-stick skillet over medium heat until shimmering. Working in batches, dip each sweet potato slice into the batter, letting any excess drip off. Place the coated slices in the hot skillet, leaving about ½-inch space between each piece. They'll expand slightly as they cook.
Cook for 2-3 minutes per side until golden brown spots appear. Here's the thing—don't press down on them while cooking. The weight will make them flat and dense instead of crispy. You'll know they're ready when the edges are golden brown and the centers still look slightly soft. This is where the magic happens—the contrast between crispy outside and chewy inside.
Finish and Serve
Transfer the cooked jeon to a paper towel-lined plate to drain any excess oil. Repeat with the remaining sweet potato slices, adding more vegetable oil to the skillet as needed—about 1 tablespoon per batch. While they're still warm, drizzle each piece with a tiny amount of the 1 tablespoon sesame oil and sprinkle with the 2 tablespoons toasted sesame seeds.
Serve immediately while crispy. The sesame seeds add a nutty crunch that complements the sweetness of the sweet potatoes perfectly. For extra flavor, dip them in a mix of the remaining 0.25 cup vegetable broth and 1 tablespoon soy sauce—this creates a light, savory dipping sauce that balances the sweetness. These jeon are best enjoyed fresh while the batter is still crispy and the sweet potatoes are warm through.
Pro Tips For Making Sweet Potato Jeon
- GRATE THIN, GRATE EVEN: I learned this the hard way—uneven shreds cook at different speeds, leaving you with a mix of raw and rubbery bits. Use the large holes of a box grater (or a mandoline if you’re fancy) and work in one direction for consistency. No, your arms won’t thank you, but your jeon will.
- SALT THE SHREDDED POTATO: This isn’t just seasoning—it’s about texture. Toss the grated sweet potato with ½ teaspoon salt right after grating and let it sit for 10 minutes. The salt draws out moisture, so when you mix it with flour, you’ll get a crispier, not soggy, jeon. (Yes, even if you’re impatient like me.)
- PRESS OUT AIR BUBBLES: Nothing ruins a jeon faster than air pockets that burn before the edges crisp. After forming your patties, press down firmly with a spatula—especially around the edges—before frying. I was skeptical until I tried it: no more half-raw centers or flare-ups.
- USE COLD EGGS, HOT PAN: Cold eggs bind better and prevent the batter from turning gummy. Whisk them in last, then let the mixture rest for 5 minutes before frying. Meanwhile, heat your pan to medium-high (350°F) and add about ¼ inch of neutral oil—enough to coat the bottom without drowning the jeon. Too little oil = sticking; too much = greasy results.
Make-ahead tips for this dish
Batter Prep Ahead
The batter is the heart of your jeon, and you can absolutely make it a day in advance. Whisk together the 1 cup flour, 2 tbsp soy sauce, 0.5 tsp garlic powder, and 0.25 tsp black pepper in an airtight container.
Cover with plastic wrap pressed directly on the surface to prevent a skin from forming. Store in the fridge for up to 24 hours—just give it a quick whisk and add the beaten eggs and green onions right before frying. This saves you time on busy days! 💡
Sweet Potato Prep
Peel and slice your sweet potatoes up to 2 days ahead—this is where meal prep shines. Store the slices in a sealed container with a paper towel to absorb moisture. When ready to cook, pat them dry again before dipping in batter.
I find this works best for batch cooking—just keep the slices refrigerated until you're ready to fry. The key is ensuring they're completely dry before cooking to maintain that perfect crisp.
Frying in Batches
Jeon are best made fresh, but you can absolutely work in batches to save time. Cook one batch, then keep the fried jeon warm in a 200°F oven on a wire rack while you finish the rest.
This maintains crispiness between batches. I like to use a 10-inch cast iron skillet because it retains heat well, but any heavy pan works. Just don't overcrowd—they need space to crisp properly. 🔥
Freezing for Later
For maximum make-ahead convenience, freeze your cooked jeon between layers of parchment paper. They'll keep for up to 2 months in an airtight freezer bag. To reheat, bake at 375°F for 8-10 minutes until crispy again.
The texture won't be quite as perfect as fresh, but they're still delicious. I like to freeze them in single layers so they don't stick together—just separate with parchment between each batch.
Dipping Sauce Prep
Make your dipping sauce ahead and store it in a small jar in the fridge for up to 5 days. Mix 3 tbsp soy sauce, 1 tbsp rice vinegar, and 1 tsp sugar in a jar with a tight lid.
Shake well before using. This tangy sauce cuts through the richness of the jeon beautifully. I often double the batch—it's perfect for dipping other Korean dishes too! ✨
Reheating Leftovers
Jeon lose their crispiness when reheated, but you can revive them with a quick stovetop method. Place them in a dry skillet over medium heat for 1-2 minutes per side—just until they're heated through and slightly crisp again.
For oven reheating, spread them on a baking sheet at 400°F for 5-7 minutes—this works best for larger batches. The key is high heat and quick cooking to restore that satisfying crunch.
Nutrition facts
Frequently asked questions
Can I use regular potatoes instead of sweet potatoes?
Regular potatoes won't give the same sweet, chewy texture that makes sweet potato jeon special. The natural sugars in sweet potatoes caramelize beautifully during frying, creating that perfect balance of crispy exterior and tender interior. If you're set on using regular potatoes, try russets for a slightly less sweet but still delicious result.
How do I make the jeon extra crispy?
For maximum crispiness, ensure your sweet potato slices are completely dry before dipping in batter. Use a heavy pan like cast iron and maintain medium-high heat. Cook in small batches without overcrowding, and resist the urge to press down on them while frying. The secret is patience—let them cook undisturbed until golden brown spots appear.
What's the best way to store leftover jeon?
Store cooked jeon in an airtight container for up to 3 days at room temperature, but they're best enjoyed fresh. For longer storage, freeze them between layers of parchment paper for up to 2 months. To reheat, bake at 375°F for 8-10 minutes or air-fry at 350°F for 3-4 minutes to restore some crispiness.
Can I add other ingredients to the batter?
Try adding 1 cup grated zucchini or ½ cup shredded cheese (like mozzarella or cheddar) for extra flavor and texture. For a heartier version, mix in ½ cup cooked shrimp or diced pork. Just be mindful not to overfill—keep the batter light for that signature crispy texture.
Why did my jeon turn out soggy?
Soggy jeon usually happen from one of three issues: wet sweet potato slices, too much batter, or low heat. First, ensure your slices are completely dry before dipping. Second, use just enough batter to coat—not drown—the slices. Finally, maintain medium-high heat and avoid overcrowding the pan. Work in batches if needed, and keep the oil hot between batches.
