Jaga Bata: Easy Butter Potato Recipe using Microwave

The cherry-blossom viewing season or the season of “Ohanami (お花見)” is just around the corner here in Japan. Speaking of Ohanami, many Japanese people prefer delicious foods offered by many street stalls at the O-hanami festival over the scenery of cherry blossoms in full bloom.

The street food stalls offer a wide range of foods from traditional Japanese snacks to popular overseas confections, so it is very difficult, but also fun to decide what to choose. And if you are an “O-matsuri (お祭り: Japanese festivals)” beginner, I would recommend “Jagabata (じゃがバター)”.

What is Jagabata (Jaga Bata)?

Jaga Bata (Jagabata)

Actually, Jagabata is a compound word composed of “Jaga (じゃが)”, an abbreviation of “Jagaimo (じゃがいも)” meaning “potato” in Japanese, and the word “bata (バター)” that stands for butter.

So Jaga Bata is a simple snack food consisting basically of plain cooked (baked, steamed, or boiled) potatoes and pats of butter, but has been a long-time favorite festival food in Japan.

Jaga Bata Recipe using Microwave Oven

When I want to eat Jaga Bata at home, I often cook it by microwaving because I’m lazy! Today, I actually made the hearty butter potatoes using a microwave oven, so for those who are interested in the recipe, here I will share it. The main ingredients you need to prepare are only white potatoes and butter or margarine.


1 First, wash the potatoes and remove the eyes from them. Wipe moisture off the potatoes with a paper towel, but leave some
2 Wrap the unpeeled whole potatoes in plastic wraps and microwave at 600w for about 5 minutes
3 Then, take the potatoes out from the oven and remove the plastic wraps, and cross-cut the potatoes halfway through
4 Place a pat of butter in the cross
5 If you want some saltiness and umami taste, sprinkle a dash of salt and the Japanese super seasoning “Ajinomoto (味の素)”
