Tempura is a popular Japanese dish typically made by deep-frying battered seafood or vegetables.

However, finding gluten-free options for tempura can be challenging, especially in restaurants.

This article will cover everything you need to know about gluten-free tempura, including the ingredients, the recipe, and how to make it at home.

What is Tempura?

Tempura is a traditional Japanese dish made by battering and deep-frying seafood, vegetables, or other ingredients.

Portuguese missionaries introduced the dish to Japan in the 16th century, and it quickly became a popular staple in Japanese cuisine.

The batter used to make tempura is usually made with wheat flour containing gluten.

This makes it unsuitable for individuals who follow a gluten-free diet.

Is Tempura Gluten-Free?

The short answer is no; traditional tempura is not gluten-free.

The batter used to make tempura contains wheat flour, which contains gluten.

Gluten is a protein found in wheat, barley, and rye.

People with celiac disease or gluten sensitivity must avoid gluten to prevent digestive symptoms and long-term health complications.

However, there are gluten-free tempura options available that use alternative flour.

Rice flour, sweet potato starch, and cornstarch are all gluten-free options for making tempura batter.

These flours have a different texture and flavor than wheat flour but can still produce a crispy and delicious batter.

Gluten-Free Tempura Recipe

Here is a simple and easy gluten-free tempura recipes that you can make at home:


  • 1 cup rice flour
  • 1/2 tsp baking powder
  • 1/4 tsp baking soda
  • 1/2 tsp salt
  • 1 cup iced water
  • One egg white (optional)
  • Vegetable oil for deep-frying
  • Gluten-free vegetables (e.g., green beans, sweet potatoes)


  • Whisk together rice flour, baking powder, baking soda, and salt in a mixing bowl.
  • Add ice water to the bowl and whisk until well combined. The mixture should have a thin consistency.
  • If you want a crispier batter, add one egg white and whisk until well combined.
  • Heat the vegetable oil in a deep fryer or a large pot to medium-high heat (350°F – 375°F).
  • Dip gluten-free vegetables in the batter until lightly coated.
  • Carefully place the vegetables in the hot oil and deep-fry until golden brown.
  • Use a slotted spoon to remove the ready vegetables from the oil and place them on a plate lined with kitchen paper towels to absorb excess oil.
  • Serve immediately with gluten-free dipping sauce or grated daikon.

Gluten-Free Tempura Batter

A gluten-free tempura batter is a simple and easy-to-make batter that uses gluten-free flour instead of wheat flour.

The batter is typically made with rice flour, gluten-free flour, or a gluten-free flour blend.

Adding baking powder or baking soda to the batter is also essential to make it crispy.

Traditional tempura batter is light and crispy; gluten-free versions can be just as good with the right ingredients and technique.

Here are some tips for making the perfect gluten-free tempura batter:

  • Use cold sparkling water instead of tap water to create a light and airy texture.
  • Add a little potato starch to the gluten-free flour for added crispiness.
  • Use medium-high heat to fry the tempura so the batter cooks quickly and doesn’t absorb too much oil.
  • Don’t overcrowd the frying pan or deep fryer with too many ingredients at a time, as this will lower the oil temperature and make the tempura greasy.
  • Make gluten-free tempura in an air fryer for a healthier option.

Tempura Dipping Sauce

No tempura dish is complete without a dipping sauce. Here’s a gluten-free recipe for tempura dipping sauce:

  • 1/4 cup gluten-free soy sauce
  • 1/4 cup water
  • One tablespoon of rice vinegar
  • One tablespoon of grated daikon radish


  • Combine 1/4 cup of gluten-free soy sauce and 1/4 cup of water in a small bowl.
  • Add one tablespoon of rice vinegar to the bowl and mix well.
  • Grate one tablespoon of daikon radish and add it to the bowl, stirring to combine.
  • Taste the sauce and adjust the sauce seasoning as needed. If you prefer a sweeter sauce, you can add a little bit of sugar or honey.
  • Pour the dipping sauce into a small bowl or ramekin and serve alongside your gluten-free tempura.

Note that you can adjust the amount of water and soy sauce to your preferred consistency, and feel free to experiment with other ingredients to make the sauce your own.

Some people like adding a bit of grated ginger or garlic for extra flavor or a dash of sesame oil for a nutty aroma.

Whatever your preferences, a good dipping sauce can take your gluten-free tempura to the next level of deliciousness.
