Tempura-style crispy green beans

By Connie Veneracion | Last updated: 03.17.2025

Lightly battered and deep-fried, tempura-style crispy green beans is served with a creamy spicy sauce made with Japanese mayo and Sriracha. Great as finger food or side dish.

Spicy tempura-style crispy green beans with Sriracha mayo dipping sauce

A dish I cooked for my daughter, Sam, who was on a vegetarian diet at the time. She isn’t anymore but this lovely vegetable dish has become a mainstay in our house. That was after I realized that even the carnivores in the family love green beans cooked tempura style. I’m quite sure that it’s the light lace-like crust that coats the vegetable that everyone finds irresistible.

Beans

Seasoning green beans and tossing with egg

To make this dish, start by trimming the green beans. Pinch off the ends and pull off the “string” that runs along the sides. If your green beans are very young, that “string” might be almost non-existent.

Batter

Dump the trimmed green beans in a mixing bowl, crack an egg directly over them and sprinkle in the seasonings. Toss to coat every piece and make sure that the seasonings are evenly distributed.

Adding corn starch to green beans to make a loose batter

Add starch and mix lightly. You’re aiming for a loose batter that easily drips off if you lift a pod. If you see small lumps of wet starch, leave them alone. Those lumps will turn into crispy bumps during frying.

Fry in batches

Frying battered green beans tempura-style

Unless you have a super large frying pan or wok, cooking the battered green beans in batches is essential to ensure that the temperature of the cooking does not drop. If you cook too many pieces and the oil temperature drops, the green beans and batter will take too long to cook. By the time the batter is golden and crisp, it will have absorbed too much oil and the green beans will be soggy.

If serving to people with low tolerance for heat, use less cayenne or omit it altogether. You might also want to go easy on the Sriracha in the dipping sauce.
