Authentic Japanese Agedashi Tofu
An izakaya classic of supreme textural harmony—pillowy silken tofu cubes dusted in potato starch and fried until delicately crisp, swimming in a shallow pool of warm, sweet-savory dashi tsuyu broth crowned with dancing katsuobushi bonito flakes and grated daikon.
History & Origins
Edo Period Tofu Hyakuchin (1782)
Agedashi tofu was formally documented in the 1782 Edo period culinary treatise ‘Tofu Hyakuchin’ (One Hundred Tofu Delicacies). The name translates directly as ‘fried and served in broth’ (age-dashi), enduring for over two centuries as an essential cornerstone of kappo and izakaya dining.
Ingredients
Tofu & Starch Coating
- •2 blocks (14 oz each) Medium-firm silken tofu (Kinugoshi) or firm tofu (Momen), drained

- •1 1/2 cups Dashi stock (awase dashi made with kombu and katsuobushi)
- •3 tbsp Japanese mirin and 3 tbsp Japanese dark soy sauce (Koikuchi shoyu)
- •1 tsp Granulated sugar
Finishing, Garnishes & Chef’s Additions
- •1/3 cup Fresh daikon radish, peeled and finely grated (daikon oroshi), lightly squeezed

Step-by-Step Instructions
PREPARATION & METHOD
Wrap each block of tofu in triple layers of paper towels, place on a rimmed cutting board, and set a flat plate with a small weight on top for 20 minutes to expel excess surface moisture. Cut each drained block into 4 even cubes.
In a small saucepan, combine dashi stock, mirin, soy sauce, and sugar. Bring to a gentle boil over medium heat, stirring until sugar dissolves completely. Lower heat and keep hot at a gentle simmer.
Heat frying oil in a heavy pot to 350°F (175°C). Just before frying, roll tofu cubes in potato starch (katakuriko), tapping off any excess powder. Lower cubes into hot oil in batches, frying 2 to 3 minutes until exterior is crisp and pale ivory. Drain briefly on a wire rack.
Place two fried tofu cubes in each individual shallow Japanese ceramic bowl. Ladle hot tsuyu broth gently around the base so the top stays crunchy. Crown with grated daikon, grated ginger, sliced scallions, and a generous pinch of bonito flakes.
Beverage Pairing
Crisp Ginjo Sake or Roasted Hojicha Green Tea
A clean, bone-dry Ginjo sake harmonizes with smoky bonito broth and sweet mirin, while nutty roasted hojicha tea complements the fried potato starch crust.
Culinary Science Insight
Potato Starch Gelatinization & Vapor Pressure Crisp
Potato starch (katakuriko) consists of exceptionally long amylose chains that gelatinize at a lower temperature (140°F) than cornstarch. When flash-fried, surface steam forms a delicate, paper-thin crystalline crust that retains crispness while softening gelatinously into broth.
