Tempura batter with cornstarch is a brilliant way to achieve light, airy, and crispy fried foods, especially when you’re aiming for the signature crunch that makes tempura so beloved. Whether you’re coating shrimp, vegetables, or even delicate herbs, a good batter is essential to achieving that perfect golden texture. Cornstarch, when used alongside other ingredients, creates a delicate crust that doesn’t feel greasy or heavy, making it ideal for those seeking an authentic Japanese-style tempura experience at home.
What Makes Cornstarch Ideal for Tempura Batter
The Role of Cornstarch in Frying
Cornstarch is often used in frying because of its ability to produce a crispy, crunchy outer layer. It has less gluten than all-purpose flour and forms a lighter texture when cooked at high temperatures. In tempura batter, cornstarch helps minimize oil absorption while delivering a crisper crust that holds up even after cooling.
When combined with cold water and minimal mixing, cornstarch helps create a batter that puffs slightly and crisps beautifully. It also adheres well to food, making it excellent for evenly coating ingredients before frying.
Benefits of Using Cornstarch in Tempura
- Produces a lighter, crispier crust compared to flour-only batters
- Helps reduce oil absorption for a cleaner taste
- Enhances the golden color when deep-fried
- Works well with various ingredients like seafood, vegetables, and tofu

Simple Pantry Staples
A classic tempura batter doesn’t require complicated ingredients. When cornstarch is added to the mix, it enhances the traditional qualities without making it overly complex. Here’s a basic list of what you’ll need:
- 1/2 cup cornstarch
- 1/2 cup all-purpose flour
- 1 large egg
- 3/4 cup ice-cold water (adjust as needed)
