Although there are different types and styles of bento boxes, most contain a starch, a protein, and an assortment of fruits and vegetables. One of the reasons bento boxes are so popular is due to the balanced nutritional profile they offer. With bento, the customer has access to several food groups, creating a well-balanced meal. Due to the portability of bento boxes, customers can take their healthy lunch or dinner options on the go.

How to Make a Bento Box

Some of the main attractions of bento boxes are their simplicity and ease of assembly. Although you can get creative with your bento box designs, standard bento boxes have three main components of a starch, a protein, and vegetables. You can mix and match different options within each food group, creating wildly different flavor combinations with the same base idea. Here are some of the most common food items to consider when making a bento box:

  • Starch - The most common starch found in bento boxes is rice, but there are other options to consider. Asian noodles are a common alternative, or you can get creative and include onigiri, Japanese rice balls made from cooked sushi rice.
  • Protein - The proteins in your bento box are where you can get the most creative due to the variety of foods you can include. Some potential proteins you can add to your bento box include chicken, beef, pork, seafood, and eggs.
  • Fruits and Vegetables - Sliced fruits and vegetables are often included in bento boxes as a side to the main course. Some examples of bento box vegetables include broccoli, carrots, peas, and edamame while you’ll find fruits such as grapes, apple slices, and cherry tomatoes.

Bento Box Origin

Bento boxes have been a part of Japanese culture for a long time, dating back almost a thousand years. The idea gained newfound prominence in the early 1900s as parents started using them as lunch options for schoolchildren. Around the same time, train stations became more common in Japan, turning bento into a popular travel food. The emergence of convenience stores and similar quick-service locations in the 1980s was also key to the recent growth in the popularity of bento boxes, launching them into the global trend they are today.

Bento Box Ideas

Bento boxes are a unique way to package and present on-the-go lunch options, allowing you to get creative with your ideas. Over time, many different variations of bento boxes have been created. Some types of bento boxes may have unique ingredients, while others may be styled into specific designs. Here are some of the most common bento box ideas that you can utilize in your establishment:

1. Ekiben

Ekiben or “train station bento” is one of the most common forms of bento found around the world. This type of bento tends to be more extravagant than other types, often using high-end ingredients like salmon or crab. Although ekiben is “travel food”, traveling is often seen as a luxury in Japan, and ekiben is designed to be a luxurious food that showcases regional flavor and ingredients. For upscale restaurants, Ekiben bento is a fantastic way to explore Japanese cuisine while providing a great take-home option for customers.

2. Konbini

Konbini is the abbreviated form of konbiniesu sutoru, the Japanese word for convenience store. In Japan, bento boxes are common in konbinis, with konbini bento being a common affordable lunch for many working-class individuals. Konbini bento is a basic bento box with the standard makeup of rice, fish, and vegetables. Although this type of bento may not be as intricate as other types, it’s simple to make and provides customers with a fantastic affordable lunch option.

3. Koraku

The literal translation of Koraku is “picnic lunchbox”, an apt name for a type of bento designed to be shared outdoors among multiple people. Traditionally, these bento boxes are enjoyed in March and April and are closely related to the Japanese Cherry Blossom Festival. Koraku bento is much larger than other bento boxes, as they are meant to serve multiple people. These are great to offer during the spring and summer months, providing customers with their very own picnic in a box.
