Make street-style Korean corn dogs at home featuring a half-and-half hot dog and mozzarella filling. This recipe gives you the signature crunch using a potato coating for an irresistible, gooey cheese pull snack.

Ingredients

Scale
  • 1 cup all-purpose flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1/4 cup granulated sugar, plus extra for dusting
  • 1 large egg
  • 3/4 cup cold water
  • 1 cup panko breadcrumbs
  • 1 cup finely diced frozen french fries or shredded potato (thawed and squeezed dry)
  • 8 hot dogs (all-beef recommended)
  • 8 mozzarella cheese sticks (low-moisture, cut to match hot dog length)
  • Wooden skewers
  • Vegetable oil, for deep frying

Instructions

  1. Prepare the fillings: Cut the hot dogs and mozzarella sticks in half lengthwise to create eight pairs of half-and-half pieces. Insert a wooden skewer through one piece of hot dog and one piece of mozzarella, stacking them together. Repeat for all sticks. Chill the assembled sticks for 15 minutes.
  2. Make the batter: In a medium bowl, whisk together the flour, baking powder, salt, and 1/4 cup of sugar. In a separate small bowl, whisk the egg and cold water. Pour the wet ingredients into the dry ingredients and mix until just combined; do not overmix. A few lumps are fine.
  3. Prepare the coatings: Spread the panko breadcrumbs on one shallow plate and the diced/shredded potato on another shallow plate.
  4. Coat the sticks: Working with one stick at a time, dip the chilled hot dog/cheese combination completely into the batter, letting excess drip off.
  5. Roll in coating: Immediately roll the battered stick in the panko, pressing gently to adhere. Then, roll it again in the diced potato, pressing firmly so the potato pieces stick all over the surface.
  6. Fry the corn dogs: Heat about 2-3 inches of vegetable oil in a deep, heavy-bottomed pot or Dutch oven to 350°F (175°C).
  7. Carefully lower 2-3 corn dogs into the hot oil, ensuring you do not overcrowd the pot. Fry for 3 to 4 minutes, turning occasionally, until the crust is deep golden brown and crispy.
  8. Remove the cooked corn dogs with tongs and place them on a wire rack set over a paper towel-lined baking sheet to drain excess oil.
  9. Serve immediately: While still hot, lightly dust the corn dogs with granulated sugar. Serve with ketchup and mustard for dipping.

Notes

  • For the best cheese pull, ensure your mozzarella sticks are fully thawed before assembly, but keep them cold until they go into the batter.
  • If you prefer a pure potato crust (Gamja Hotdog style), skip the panko and only use the diced potato coating.
  • Maintain your oil temperature carefully; if it is too cool, the crust will absorb too much oil and become greasy.
