Tempura is a delightful Japanese dish known for its light and crispy texture. The secret to achieving this perfect crunch lies in the batter, which is made using a few simple ingredients. This recipe will guide you through creating a tempura batter that is ideal for coating vegetables, seafood, and more, resulting in a deliciously crispy exterior.
The key ingredient in this recipe is ice-cold water, which helps create a light and airy batter. Make sure to use all-purpose flour for the right consistency. You will also need a large beaten egg to bind the mixture together. These ingredients are commonly found in most supermarkets, but it's crucial to ensure the water is ice-cold for the best results.

Ingredients For Tempura Batter Recipe
All-purpose flour: This is the base of the batter, providing structure and a light texture.
Ice-cold water: Essential for creating a light and crispy batter, the cold temperature helps prevent gluten formation.
Large beaten egg: Acts as a binder, helping the batter adhere to the ingredients and contributing to the overall texture.
Technique Tip for Tempura Batter
When preparing tempura batter, ensure that the water is ice-cold. This helps create a light and crispy texture. Additionally, avoid overmixing the batter; it should remain lumpy to achieve the desired consistency.

How to Store / Freeze Tempura Batter
To store your tempura batter in the refrigerator, transfer it to an airtight container. The batter can be kept for up to 1 day. Before using, give it a gentle stir to recombine any separated ingredients, but avoid overmixing to maintain its lumpy texture.
For longer storage, freezing is an option. Pour the tempura batter into a freezer-safe, airtight container, leaving some space at the top for expansion. Label the container with the date. The batter can be frozen for up to 1 month.
When you're ready to use the frozen batter, transfer it from the freezer to the refrigerator and let it thaw overnight. Once thawed, give it a gentle stir to bring it back to the right consistency. Again, avoid overmixing to keep the batter lumpy.
If you have leftover fried tempura, you can store it in the refrigerator for up to 2 days. Place the pieces on a plate lined with paper towels and cover them with plastic wrap or foil. To reheat, place the tempura on a baking sheet and warm it in a preheated oven at 375°F (190°C) for about 10 minutes, or until crispy.
For freezing fried tempura, let the pieces cool completely, then arrange them in a single layer on a baking sheet. Freeze until solid, then transfer to a freezer-safe bag or container. Label with the date and freeze for up to 1 month. To reheat, place the frozen tempura on a baking sheet and bake in a preheated oven at 375°F (190°C) for 15-20 minutes, or until heated through and crispy.
Always ensure that your tempura batter and fried tempura are stored properly to maintain their quality and safety.
How to Reheat Leftovers
Preheat your oven to 375°F (190°C). Place the leftover tempura on a baking sheet lined with parchment paper. Bake for 10-15 minutes, or until the tempura is heated through and crispy.
Use an air fryer set to 350°F (175°C). Arrange the tempura in a single layer in the basket. Air fry for 5-7 minutes, shaking the basket halfway through to ensure even reheating.
Heat a skillet over medium heat and add a small amount of vegetable oil. Once the oil is hot, place the tempura in the skillet. Fry for 2-3 minutes on each side, or until the tempura is crispy and heated through.
For a quick microwave method, place the tempura on a microwave-safe plate lined with a paper towel. Microwave on high for 1-2 minutes. Note that this method may not retain the crispiness as well as other methods.
If you have a toaster oven, preheat it to 375°F (190°C). Place the tempura on the toaster oven tray and heat for 8-10 minutes, or until crispy and warm.
Best Tools for Making Tempura Batter
Mixing bowl: A large container used to combine the flour, ice-cold water, and beaten egg. It allows for easy mixing without spilling.
Whisk: A utensil used to lightly mix the flour and water, and then gently stir in the beaten egg. It helps to incorporate the ingredients without overmixing.
Deep fryer: An appliance used to heat the oil to the precise temperature of 350°F (175°C). It ensures even frying and maintains a consistent temperature.
Large pot: An alternative to a deep fryer, used to heat the oil. It should be deep enough to submerge the ingredients fully.
Thermometer: A tool used to check the oil temperature, ensuring it reaches and maintains 350°F (175°C) for optimal frying.
Tongs: A utensil used to dip the ingredients into the batter and then place them into the hot oil safely.
Paper towels: Used to drain the fried ingredients, absorbing excess oil and keeping them crispy.
Plate: A flat dish used to hold the fried ingredients after they have been drained on paper towels.
How to Save Time on Making Tempura Batter
Prepare ingredients in advance: Measure and chop vegetables or seafood before starting the batter to streamline the process.
Use a thermometer: Ensure the oil is at the correct temperature of 350°F (175°C) for optimal frying.
Keep batter cold: Place the batter bowl over ice to maintain its cold temperature, ensuring a crispier result.
Batch frying: Fry similar-sized items together to ensure even cooking and save time.
Drain properly: Use a wire rack instead of paper towels to drain excess oil quickly and keep the tempura crispy.
