Fresh vegetables dipped in a tempura batter, then fried to a perfect crisp. These Tempura Vegetables are best served with a wasabi dipping sauce, making an addictively tasty dish.

Frying
I’ll be honest here, I don’t actually like to fry food. It’s kinda messy, and I don’t like cleaning it up. Plus, I know that frying isn’t the healthiest way to prepare food.
BUT, I love the taste of fried food. So, every once in a while I decide to overcome my hesitations and break out the fryer.

Tempura Vegetables
Inspiration
My husband and I like to go on a Caribbean vacation every few years if we’re able. On one trip to Jamaica, we ate at a Japanese restaurant that served tempura vegetables.
I’m sure I’ve had tempura vegetables before that trip, and since that trip, but those veggies stand out in my mind. They were so crispy, yet soft, and all around delicious.
Tempura Batter Without Carbonated Water
The first time I attempted tempura vegetables at home, I looked up a number of recipes; most called for carbonated water. At the time, the only carbonated water I had around was flavored, which clearly wouldn’t work.
I experimented with various other techniques and landed on using baking soda with cold water. It was a success.

Seasoning the Batter
My first few attempts at the batter, I didn’t add any seasoning, including salts. No good.
I experimented with different seasonings and found that many took away from the tempura taste. The answer was salt alone, and I landed on using 1/2 teaspoon salt as the optimum amount.
Dip
The dip took multiple attempts to get just the flavor I wanted – spicy, but not too spicy, and flavorful. I ended up using:
- Greek Yogurt
- Sour Cream
- Wasabi
- Salt
- Soy Sauce
- Worcestershire Sauce
If you like spicy food, consider increasing the wasabi. I used a small amount to give it just a little heat.

These Tempura Vegetables with Wasabi Dipping Sauce are an addictively tasty appetizer, side, or snack!
