Agedashi tofu is a delicious deep-fried tofu in a dashi-based broth, usually served as an appetizer in Japanese restaurants. This Agedashi-style recipe includes my simple method for making an amazing homemade dashi broth. Katsuobushi dashi is the perfect bath for my perfectly fried yet fluffy tofu.
Why You Should Make This Recipe
Agedashi tofu is traditionally made with potato or rice flour, but this recipe has been thoroughly tested to be made with arrowroot powder, cornstarch, rice flour, potato flour, or all-purpose flour so you can make it with whatever you have on hand.
Agedashi tofu is also traditionally made with silken or medium-firm tofu, but this recipe has been developed using medium or firm tofu, which is much easier to handle and fry without it falling apart. And it still yields that fluffy interior texture.
Tofu has a long shelf life in the fridge and it’s a great protein alternative. And it cooks quickly. I usually double the dashi recipe and freeze half for another night. Then, all you have to do is add the sauce ingredients and fry up the tofu for an easy weeknight dinner.
Ingredients & Substitutions
Tofu – Use firm or medium firm tofu for this recipe. For a complete guide to cooking with firm tofu, you can check out this firm tofu guide.
Flour – You can use arrowroot powder, cornstarch, rice flour, potato flour, or all-purpose flour. All have been tested with great success in this recipe, and my preference is arrowroot powder or cornstarch.
Flavorless oil – You can use sunflower seed, canola, or vegetable.
Ginger – Use fresh stem ginger, grated.
Nori seaweed – this is an optional addition for garnish.
Mirin – This is a rice wine, usually found in the oils and vinegar section of the grocery store.
Soy sauce – I usually use tamari or a light soy sauce, but any soy sauce will work in this recipe.
Arrowroot powder – This starch serves as a thickening agent in the dashi-based sauce and can be substituted with cornstarch.
Kombu seaweed – This is a brown algae you can buy in small packs.
Dried bonito flakes – You can sub these with dried shiitake mushrooms as a vegan option
How to Make This Recipe
Start by making the dashi broth, then fry the tofu and make the sauce. Prepare the dashi by soaking the kombu in water for 30 minutes in the refrigerator. Next, heat the water on low heat without letting it come to a boil.
Remove the kombu, add in the bonito flakes, and bring the water to a boil. Turn off as soon as it comes to a boil and steep for 10 minutes.
Then, strain out the bonito flakes.
You can make the dashi in advance and freeze it, just as you would stock. However, the complete sauce does not freeze well. So freeze the dashi at this stage.
Making the Sauce with Your Dashi
Before you start the sauce, dry the tofu by draining as much water out as possible. Surround the tofu with paper towels, and top with a book or plate to add even pressure and draw the water out. Let it sit for 30 minutes.
To finish making the sauce, add the 24-30 oz. of dashi (the seaweed liquid made in step 1), mirin, and soy sauce to a saucepan.
Heat over medium heat until it comes to a boil. Then, reduce to low. Mix the arrowroot powder with the water in a small bowl until dissolved and then stir into the sauce until thickened. Then turn off the heat.
Make sure the sauce is warm when you add the arrowroot and water mixture. If it isn’t, the sauce will not properly thicken.
How to Fry the Tofu
Cut the tofu into 1.5-2 inch blocks. I usually get 9-12 out of each of my 1 lb. blocks, depending on the brand of tofu.
Heat 1/4-inch of flavorless oil in your non-stick fry pan. Roll the tofu in flour, and fry over medium heat for 2 minutes per side.
Always use a non-stick fry pan to fry the tofu. If you do not use a non-stick pan, you will need at least 1 inch of oil, or preferably a full deep-fry amount of oil, or the tofu will stick.
You only need to cook 4 sides of the tofu rather than all 6. To remove excess oil, transfer to paper towels after frying.
Bringing it All Together
Plate your tofu by adding four or five pieces of fried tofu. Then, pour some of the dashi sauce over the tofu and into the bowl. Garnish with grated ginger, scallion slices, and seaweed.

I don’t usually rate a recipe before I’ve actually made it, but I’ve been eager to make this at home and I will be trying it soon. My crystal ball tells me it will be a five star hit!
I have a question—do you think it would work to do the tofu in my deep fryer? Thanks.
It will absolutely work in your deep fryer… it actually works even better! I fry them in shallow oil only to reduce oil waste. Enjoy!
This recipe is just awesome for Japanese Fried Tofu. Peel and grate the daikon and gently squeeze water out. Put dashi, soy sauce, and mirin in a small saucepan and bring to boil. we can also add some monosodium glutamate(msg) to it just to enhance the flavor of the sauce.
Thank you for sharing… I’m glad you liked it. Your additions sounds so good, Sharon!
Method sounds good, but authentic agedashi is made with potato flour dredging as well as Japanese silken tofu (not firm). Make those changes next time you try and I promise you’ll never go back! <3
This definitely isn’t a traditional agedashi tofu… your way is much more like the traditional. My version uses ingredients I always have on hand… Both ways work great!
My husband and I love Japanese food, especially agedashi tofu. I really had never considered making it at home until Covid came along. We were craving agedashi, so I found your recipe, ordered all the ingredients and made it myself. This recipe is better or at least as good as any we’ve had in a Japenese restaurant. I’m making it again tonight! Thanks so much for the recipe!
You just made my day, Teresa! I created this recipe because I live too far from my favorite place to get agedashi tofu, and wanted something just as good. Thank you for your kind words… I’m so glad you liked it!
I dreamed up a variation on agedashi tofu.
– First, while still in the tub they came in , let it freeze overnight.
– Let the tofu package thaw, drain it.
– Cut into “steak squares”, then press out all of the water.
– Put the tofu steaks in a LARGE plastic storage bag and add the ketjap manis (aka sweet soy sauce). Let marinate overnight.
-Next day, dredge the “steaks” in a combination of: potato starch, and bit of cumin and coriander.
-Then, shallow fry the steaks until crisp and golden.
– Serve with a peanut sauce or a soy sauce-sesame oil mixture.
That sounds so, so good, Mara!! Wow. Dreaming up recipes is the best. And this one sounds like it is worth making. Yum!
