Introduction

Dubu-gangjeong (두부강정) is crispy fried tofu tossed in a glossy, sticky glaze – the tofu version of dakgangjeong. The sauce is built on the same sweet-spicy idea as Korean fried chicken sauce (see our yangnyeom sauce guide), but it is usually a little lighter so the delicate tofu stays the star. It is a popular lunchbox side dish, a kids’ favorite and an easy meat-free main.

What is Dubu-gangjeong Sauce Made Of?

The word gangjeong originally referred to a sweet glazed snack, and today it describes anything fried and coated in a sticky syrup-based sauce. The glaze starts with soy sauce and a Korean syrup such as jocheong (rice syrup) or mulyeot, which gives the shine and stickiness. Common styles:

• Soy garlic (ganjang): soy sauce, syrup, garlic – not spicy, great for kids.
• Sweet and spicy (yangnyeom): gochujang and ketchup added for a red glaze.
• Ketchup style: mostly ketchup and syrup, tangy and very mild.
• Nutty finish: topped with crushed peanuts or sesame seeds.

What Does Dubu-gangjeong Taste Like?

Each cube has a thin, crisp, starchy shell that soaks up a sweet, garlicky glaze, while the inside stays soft and creamy. The spicy version adds gentle chili warmth and a fermented depth from gochujang; the soy version is more like teriyaki with extra garlic.

Easy Dubu-gangjeong Recipe (Serves 2–3)

Ingredients

• 1 block (14–16 oz / 400–450 g) firm tofu
• 1/4 tsp salt and a pinch of black pepper
• 4 tbsp potato starch or cornstarch
• Neutral oil for shallow frying (about 1/2 inch / 1 cm in the pan)

Sweet and spicy sauce

• 1 1/2 tbsp soy sauce
• 1 tbsp gochujang (leave out for a non-spicy version)
• 1 tbsp ketchup
• 2 tbsp rice syrup or honey
• 1 tsp sugar, 1 tbsp minced garlic, 3 tbsp water
• 1 tsp sesame oil and 1 tsp toasted sesame seeds

Instructions

1. Cut the tofu into 3/4-inch (2 cm) cubes. Spread on paper towels, sprinkle with salt and pepper and press gently with more towels for 10–15 minutes to remove moisture.
2. Put the starch in a bag or bowl, add the tofu and toss until every side is coated. Shake off the excess.
3. Heat the oil in a wide pan over medium-high heat. Fry the tofu in batches, turning, until golden and crisp on all sides, 6–8 minutes. Drain on a rack or paper towels.
4. Wipe out most of the oil. Add all sauce ingredients except sesame oil and seeds, and simmer over medium heat for 1–2 minutes until bubbly and slightly thick.
5. Turn off the heat, add the tofu and toss quickly to coat. Finish with sesame oil and sesame seeds and serve right away.

Tip: Dry tofu is the secret to crispiness and also reduces spattering. Add the tofu to the oil gently and away from you, never leave hot oil unattended, and keep a lid nearby in case of flare-ups.

How to Store Dubu-gangjeong and the Sauce

Dubu-gangjeong FAQ

What kind of tofu is best for dubu-gangjeong?

Firm tofu. Extra-firm works too; soft or silken tofu falls apart when fried. Read more in our Korean tofu guide.

Can I make dubu-gangjeong in an air fryer?

Yes. Spray the starch-coated cubes with oil and air fry at about 400°F (200°C) for 15–18 minutes, shaking halfway, then toss with the warm sauce.

Is dubu-gangjeong vegan?

It can be: use rice syrup or sugar instead of honey and check that your gochujang and ketchup contain no animal products.

Why did my tofu get soggy?

Usually the tofu was too wet, the pan was crowded, or it sat in the sauce too long. Toss just before serving.
