Kitsune Udon — Udon Noodles with Sweet Fried Tofu
This kitsune udon recipe cooks thick, chewy udon noodles in a clear dashi broth and tops them with aburaage — fried tofu pouches simmered until sweet and savoury. The name comes from the kitsune, the fox of Japanese folklore, said to love fried tofu. One serving is about 590 g.
Kitsune udon is named for the kitsune, the fox of Japanese folklore, which is said to love fried tofu — so a bowl of udon topped with aburaage became the fox's udon. The dish is closely tied to Osaka, where thick udon in clear dashi is an everyday lunch, and the sweet simmered tofu pouch on top is what sets it apart from plain udon.
Pairs well with: Pickled ginger and a small plate of tempura

A good kitsune udon has a clear, fragrant broth, springy noodles and one glossy, sweet tofu pouch on top.
Execution Methodology & Culinary Technique
Prep Stage: Blanch the Tofu, Slice the Onions
15 Mins • Knife Work
Blanch the aburaage for a minute to wash off excess frying oil, then simmer it briefly in a little soy, mirin and sugar so it turns sweet and glossy. Slice the spring onions while the tofu simmers, and measure the broth seasonings so the soup comes together in minutes.
Maestro Tip: Do not skip the blanch — unblanched aburaage makes the broth greasy.
8 Mins Simmer, ~95°C (203°F)
Blanch the aburaage in boiling water for 1 minute, drain, and gently squeeze out the water. Put it in a small pan with 2 tablespoons of water, 1 tablespoon of the soy sauce, 1 tablespoon of the mirin and half the sugar. Simmer for 5 minutes until the pouches are glossy and sweet, then set aside.
Keep the heat low — a hard boil tears the soft pouches.
Done when: Tofu is glossy, plump and sweet-savoury all the way through.
5 Mins Simmer, ~95°C (203°F)
Bring 1.2 litres of water to a boil, stir in the dashi powder, then add the remaining soy sauce, mirin and sugar. Simmer for 2 minutes and taste: it should be savoury and lightly sweet, not salty. Keep the broth hot on the lowest heat.
Taste before adding more soy — dashi powder is already salty.
Done when: Broth is clear, fragrant and balanced.
10 Mins Boiling, 100°C (212°F)
Cook the udon in a separate large pot of boiling water for 8–10 minutes (or as the pack directs) until thick, chewy and springy. Drain well and rinse briefly under hot water to wash off the surface starch — this keeps the broth clear.
Cooking the noodles separately is the secret to a clear broth.
Done when: Noodles are chewy with no hard white core.
2 Mins Hot, ~85°C (185°F)
Divide the noodles between four deep bowls, ladle over the hot dashi broth, and lay one sweet tofu pouch on top of each bowl. Scatter with spring onions and serve at once, while the noodles are still springy.
Warm the bowls with hot water first so the soup stays hot to the last spoonful.
Done when: Each bowl has noodles, clear broth, one tofu pouch and green onions.
Finishing Touches & Plating
Serve the kitsune udon at once, with chopsticks and a spoon, so the noodles stay springy and the tofu stays warm on top of the broth.

Food Pairings
To optimize nutrient absorption and elevate the sensory depth, pair with these authentic accompaniments:
Sides
Vegetable Tempura
Crisp tempura adds crunch and contrast to the soft noodles and clear broth — the classic udon-shop partner.
Vegetables
Pickled Ginger
Sharp, pink pickled ginger cuts through the sweet tofu and refreshes the palate between mouthfuls.
Drinks
Green Tea
Unsweetened green tea is light and clean, and it suits the delicate dashi flavour better than a sweet drink.
Full Menus
As Part of a Japanese Lunch
Serve the udon with a small tempura plate and pickled ginger — the soup is the warm centre of a light lunch.
Complete menu
Serve the udon with vegetable tempura and pickled ginger on the side, and finish with unsweetened green tea.
Digestive Guardrails
To prevent digestive distress, sluggishness, or palate clash, avoid pairing the dish with these elements:
A Second Salty Soup
The dashi broth is already salty; serving another salty soup alongside it pushes the meal's sodium too high. Choose pickles or tempura instead. This is general guidance, not medical advice.
Overcooking the Noodles
Udon left in the broth goes soft and swells, and the broth turns cloudy. Cook the noodles separately and serve at once.
