📋 Ingredients

Here are the ingredients (amounts are in the recipe card below).

Ingredients for kabocha tempura.
  • Kabocha – Cut kabocha into thin slices with the skin.
  • Oil – I love using White sesame oil (taihaku) or rice oil to get an extra crispy texture. White sesame oil may be hard to get if you don’t live in Japan, so you can use your regular cooking oil (such as vegetable oil) and add toasted sesame oil to add flavor.
  • Batter – This recipe uses water, cake flour, and baking powder. No egg is required.
  • Tentsuyu (Tempura sauce) – This is the tempura dipping sauce. Put grated daikon radish in mentsuyu (noodle soup) in this recipe. You can find a homemade mentsuyu recipe in the Kake soba noodle recipe.

Tempura Batter Mix

The easiest way to make tempura batter is by using a store-bought mix. You add water and mix it up.

But we won’t use it as we can easily make the batter with simple ingredients.

Helpful Tips for Making Crispy Tempura

Tips for Batter

The batter is the key to the success of your Tempura.

It is essential to avoid forming gluten in the batter! Otherwise, you will get a pancake-like heavy texture, not crispy!

So, let’s check the following easy and simple tips to make your Tempura perfect!

tempura batter.

1. Use cake flour

Use cake flour with a lower gluten content (about 7%). Do not use bread flour with a high gluten content (about 13%).

You can substitute it with all-purpose flour, which is 8% gluten.

2. Use cold water

Use cold water rather than lukewarm water because gluten is easily formed at high temperatures. It’s also better to chill the flour if possible.

3. Shift the flour

Shifting the flour makes the texture finer and lighter as air comes in.

4. Do not mix it until smooth

If you combine the batter ingredients too much, the gluten will be formed, and your Tempura will be heavy and chewy.

5. The timing to make the batter

The batter will become sticky over time, so making it right before frying is better.

Other Tips

deep-frying kabocha tempura in a frying pan.

1. Dust flour on the ingredients

If you dust ingredients with flour, the extra surface will reduce the water content of vegetables and keep them from getting soggy.

In addition, the batter sticks to vegetables, and you can fry them without having the tempura skin come off.

So dust bell peppers and eggplants (which contain a lot of moisture) with flour. Kabocha and sweet potatoes are not necessary.

2. Do not fry too many at once

You will lower the temperature of the oil by adding many ingredients to the pot.

Then, the moisture in the batter will not evaporate well, and your Tempura might become soggy.

To keep the oil temperature consistent, put the ingredients in less than 2/3 of the pot and save some space open.

3. Remove Tenkasu (Agedama)

Tenkasu (or agedama) is crunchy bits made from the leftover batter during cooking tempura.

If you leave them in the pot, old tenkasu stick to the new Tempura and ruin the texture.

So, remove the tenkasu with a fat skimmer slotted spoon before adding the new Tempura to the pot.

4. Drain off the oil

Draining oil after frying is also essential.

After cooking the Tempura, remove any excess oil by placing them on a cooling rack. Keep them upright as much as possible, and do not stack them.

How to eat it

If you go to a Japanese restaurant, Tempura is commonly served with tentsuyu (tempura sauce) or just salt.

But at home, you can enjoy more options. Here’s how to eat Tempura!

tentsuyu and daikon oroshi.
  • Tentsuyu: It’s a dipping sauce for Tempura made from soy sauce and dashi. See the following section for more details.
  • Salt: Add a little table salt (or sea salt) on top and eat it; then, you can enjoy the simple taste. You can also use flavored salts such as matcha, spicy, citrus, etc.
  • Soy sauce: Add a bit of soy sauce. Do not dip the tempura in it as it is salty and overpowers the taste of Tempura.
  • Chuno sauce (Japanese Worcestershire-style sauce): Add the sauce to your taste.
  • Or without any condiments.

When I was a child, I would eat Tempura with soy or tonkatsu sauce, but now I like tentsuyu with grated daikon radish, which helps digestion.


Tentsuyu is a special dipping sauce for Tempura made from dashi (soup stock), soy sauce, and mirin.

Mentsuyu (noodle soup) is made from the same ingredients, and it’s easier to get at a store, so I use store-bought mentsuyu for this recipe. (You can also check my homemade mentsuyu recipe here)

Adding grated daikon to tentsuyu is common as it helps digest fatty food like Tempura. You can also add lemon juice or grated ginger for the same reason.

If you are a vegetarian

Store-bought tentsuyu or mentsuyu include dashi stock made from fish, so you should avoid using them.

  • Make the batter: Add cold water to a bowl, sift the flour and baking powder with a strainer, and mix.
