What is Yudofu?
Yudofu (湯豆腐) is an easy and comforting tofu dish, where cubed tofu is gently heated in a pot with water and kombu and then served warm. You can kind of say this dish is a hot version of Hiyayakko (chilled tofu).
While traditionally paired with straightforward dipping sauces like soy sauce or ponzu, this recipe introduces a unique twist to the sauce. This subtle change adds an extra layer of flavor, offering a fresh take on the classic Yudofu.
How I Developed This Recipe
Yudofu is traditionally a comforting dish where tofu is gently simmered in kombu dashi and served with classic, simple condiments like soy sauce, ponzu, green onions, and sesame seeds.
For a bit of twist, my recipe introduces a spicy sesame sauce to the mix, adding a small kick to the mild flavors of the tofu.

Key Ingredients & Substitution Ideas
- Silken Tofu: I used silken tofu for its smooth texture, but firm type is also a great choice. Did you know? It is said that roughly 60% or more of people in Japan prefer to use silken tofu for Yudofu.
- Dried Kelp (Kombu): For this recipe, we always boil the tofu in kombu dashi. Curious about what makes kombu so special? Check out Kombu 101 article to know the umami components and the different types available.
- Sesame Paste: In Japan, we call it “neri goma (ねりごま)” and it’s what I use as the base for the sauce. If you can’t find it, unsalted smooth peanut butter or tahini are great substitutes.
- Chili Oil: I recommend sesame oil-based “raayu” for matching kick, but any chili oil you have will do the trick.
- Rice Vinegar: It’s our go-to vinegar in Japan, but if it’s hard to find, apple cider vinegar or white vinegar are fine swaps.
- Soy Sauce: I used dark soy sauce in my recipe. If you’re wondering about how it differs from light soy sauce, take a peek at my soy sauce guide.
- Sugar: I use caster sugar that dissolves easily since we don’t heat it up in this recipe. It mixes in seamlessly this way.

This section aims to provide a comprehensive overview of the cooking steps and techniques with visuals. I will also include more in-depth tips and tricks than the recipe card.
Begin by placing a piece of kombu in a large pot filled with water. I let it soak there for about 30 minutes.
While the kombu is soaking, prepare the sesame sauce. Mix all the sauce ingredients together in a bowl. I used a mini food processor for speed.
Getting the sauce ready beforehand makes everything else easier because I can just pour it over the tofu later without rushing in the kitchen.
After the kombu has rehydrated, turn the heat up to medium. While you wait, drain the pack of tofu and cut it into 6-8 pieces depending on how many servings you want to make. Remove the kombu just before the water starts to boil.
Once the kombu is removed, turn the heat down to low and gently add the tofu to the pot. Sprinkle some salt into the water here too.
Once the tofu is hot, use a slotted spoon to lift each piece out of the pot and onto a serving plate. I make sure to drain each piece well so it doesn’t make the plate soggy or dilute the sauce.
Then, drizzle the sesame sauce generously over the top of the tofu.
Sprinkle chopped green onions over the tofu to finish.

- Shogayaki Pork: The refreshing spiciness of the ginger matches the simple flavor of the yudofu.
- Karaage Chicken: If you want to pair it with fried food, I recommend karaage! If you want a citrusy taste, lemon-flavored fried chicken is a good choice!
- Saba no Shioyaki: If you want to pair it with a fish dish, I recommend grilled mackerel! It is a good combination that does not interfere with both flavors.
How to Store
I do not recommend storing the tofu, but you can refrigerate the leftover sesame sauce for about 1 week.
