A bento box is simply a boxed meal with compartments separating toppings or courses. Bento is derived from a Chinese word meaning "convenient," and at its most basic, it’s lunch packed to be eaten on the go and has existed since the 12th century.
Bento-style meals and boxes have roots in Asian cuisines, including Chinese, Japanese, and Korean, but have since spread through the rest of the world. The main section of the box traditionally held rice or noodles, but bento boxes can be used to contain everything you need for cheese and charcuterie, picnic spreads, on-the-go snacks, and more.

It’s made entirely from stainless steel, with no gaskets, plastics, or silicone, so it’s dishwasher safe when the box comes home at the end of the day.
The latches are easy enough for kids to use, but latch securely, so the box will stay closed until it’s time for lunch.

This bento box is designed for salad—although it could be used for other meals easily—with a large, 6.75-cup bottom container for greens, three upper compartments (one 10-ounce and two 5-ounce) for crunchy bits, wet vegetables, like tomatoes and cucumbers, and other tasty add-ins.
A central lidded 3-ounce section is ideal for salad dressing, so it can be added right before serving, and a matching fork snaps onto the lid, keeping it clean and handy.

It’s leakproof, so it can handle wet foods, and comes with its own matching insulated lunch bag to make it easy to carry and hold the temperature. With the lid on, the compartments are sealed from each other, so wet foods won’t leak into other compartments—meaning your salad dressing won’t soak the sandwich.
The box is freezer safe, so it can be frozen ahead of time to keep lunch chilled, and it’s microwave safe with the lid removed, so lunch can be served warm. At the end of the day, it’s dishwasher safe, as well. This has two small 7-ounce compartments and one larger 14-ounce compartment.

Best Disposable: Freshware 2 Compartment Meal Prep Containers With Lids
Great for food prep
Not recyclable in all areas
Reusable food containers are a great idea, but sometimes it’s just more trouble than it’s worth to keep track of an empty, dirty food container to take it home to be washed and reused. That’s where these containers come in. They’re microwave-, freezer-, and dishwasher-safe, so they can be reused if you choose, but they’re inexpensive enough that if one gets left on the school bus or accidentally gets tossed in the trash at work, it won’t break the budget.
These have two compartments and hold a total of 25 ounces, so there’s plenty of room for a sandwich and chips or salad and cheese. This is a pack of 15 containers with lids, but for serious meal preppers, they’re also available in a bulk of 150.
Materials: BPA-free plastic | Compartments: 2 | Size: 25 ounces
Best with Flatware: Jeopace Bento Box
Hand washing recommended
Dividers can't be adjusted
Three compartments in this box keep foods separate, so the cookies won’t touch the salad. The box is leakproof, too, so it won’t make a mess in a backpack, but liquids can transfer between compartments, so it shouldn’t be tipped if foods are saucy. These are freezer- and microwave-safe for easy prepping and fast reheating.
They’re also top-rack dishwasher safe, but hand washing is recommended to avoid warping the lid. The bento box holds about 38 ounces, so there’s plenty of space for lunch or dinner, and the included fork means there’s no need to borrow the good flatware from the kitchen.
Materials: BPA-free biodegradable wheat straw plastic | Compartments: 3 | Size: 30 ounces
What to Look for When Buying a Bento Box
As you may expect with something that has been in use for nearly a millennia, Bento boxes and meals vary widely. At its most basic, a bento box is a tray with a lid (either attached or detached) for ease of transportation. Both traditional and more contemporary bento can come in a variety of shapes and sizes but are generally either square or round. Bento meals also typically feature a variety of foods that are divided using trays or even separate compartments that are often stacked. Dividers can be fixed or moveable, allowing you more control over the portions.
The first bento were made from bamboo, then later lacquered boxes and wood, such as cedar. Beginning in the 20th century, other materials began to be used, starting with aluminum in the 1920s. Today, you can still find bento boxes made from traditional materials as well as stainless steel, plastic, and glass. Single-use bento, common in Japan at convenience stores and sometimes found abroad as well, are typically single-use plastic or even styrofoam.
Another change in bento boxes in the 20th century was the introduction of insulation in the design. Japanese insulated bento tend to come in separate containers and resemble a Western-style lunchbox, with a thermos cup that fits into an insulated or non-insulated soft carrying case. The more common insulated option tends to be bento-inspired lunchboxes made by Western companies, often with a removable tray inside an insulated case. You can also find non-insulated bento that come with an insulated carrying case.
Bento boxes are designed with a single serving meal in mind, but can still vary in size. While there’s no one meal packed in a bento, recipes and meal ideas tend to have a mix of proteins, carbs (typically rice), vegetables, and fruits. If you balance out your foods, you can typically create a filling meal even in a smaller bento box. But if you want a big salad, for example, you may need to find a bento box specifically designed for a big pile of greens so you’re not left hungry. You can also consider how many foods you’re likely to want to pack: A bento with lots of small compartments could be great if you like variety or pose a problem if you typically want just a main and a side.
Early bento lids were completely separate from the base of the box and often tied up in furoshiki, a traditional Japanese wrapping cloth, to help keep it secure. Today, tops of boxes are often more secure, with lids and seals that resemble other food containers. Tops can be held in place with clasps, airtight lids, or gaskets. Lids are also often hinged, making it easy to keep all parts of the box together. Lids vary in how leak- and splash-proof they are, so think about how much you’ll need to transport your bento, and even how far ahead you want to prep your food; an airtight seal will help keep food fresher longer and prevent food from spilling in your bag.
Not surprisingly, before the advent of the microwave, bento meals were eaten cold. Today, like with all packed meals, it’s often a matter of preference. If you want to heat up meals, make sure your bento is microwave-safe. Additionally, no matter your plans, ensure any plastic is BPA-free.
Simple bento typically start at around $15, going up to around $30 as features like insulation and spill-proof seals are added. More design-focused bento, as well as indestructible models with kids in mind, tend to be on the more expensive side. Traditional wood bento is, perhaps surprisingly for those not familiar, the most expensive. Because they are still handmade, wood bento can cost upwards of $100.
Types of Bento Boxes
For most of history, bento boxes were made from wood, woven bamboo, or lacquered wood. Bento made from traditional materials are still available today, though many people now opt for easy-to-care-for plastic or metal bento. Many so-called lacquer boxes you may find online, for example, are often made from plastic mimicking the high shine of lacquer.
Modern bento come in nearly every conceivable shape, size, and color. They typically feature designs that make them amenable to everyday use, including light and easy-to-care-for materials as well as spill-proof lids. Plastic bento can also mimic more traditional designs that were once made with lacquer.
As with Western-style lunch boxes, bento boxes can be licensed with favorite characters or use bright, colorful designs to appeal to children. For Western parents, the appeal of bento boxes is often that it helps build in variety for school lunches—and avoid single-use plastic bags. Bento boxes marketed to children in America often feature tight seals and clasps for preventing splashes and come in bright colors.
Less common in the West, disposable bento meals are often sold to-go in single-use plastic trays. You may be able to find these at Japanese markets or even in to-go orders at Japanese restaurants. Disposable meal prep containers, with separate compartments, offer similar single-use convenience.
Bentgo is one of several American companies that adapts traditional bento for a Western audience, offering products like salad bento and children’s bento boxes with a sandwich-sized compartment. Its products are also often insulated.
A California company, ECOlunchbox offers stainless steel and plastic-free bento-style lunchboxes. It also sells stainless steel inserts and accessories.
After eating out of your bento, simply wash and dry it until next time. Some bento, especially insulated models, have removable inside trays that can be washed, and the exterior is only cleaned as needed. Traditional materials, like bamboo or wood, require more care and must be hand-washed. Lacquerware can even peel and chip in the wrong environment—it’s little wonder people opt for materials like metal and plastic when given the chance for this everyday product.
What is a bento box?
Bento is a single-portion meal designed to be taken to go. Of Japanese origin, today bento is popular all over Asia and, increasingly, the West.
What is in a traditional bento box?
Originally, bento would have been fairly simple, just containing rice for a traveler. Over the centuries, bento developed to reflect trends in Japanese cooking. A bento will typically contain rice or noodles alongside a protein, like fish or pork, as well as vegetables. Other common items include tamagoyaki (a Japanese rolled omelet), potato or pasta salad, and fruit salad.
Do bento boxes keep food warm?
Most bento boxes are not fully insulated, like with a thermos. They can, however, be stored in an insulated carrying case.
Are bento boxes microwavable?
For most of centuries people have eaten bento meals, the food was eaten at room temperature. With the advent of refrigerators and microwaves, many of us store food for hours before eating it at low temperatures or may just want a piping-hot meal away from home. Many bento boxes are microwave safe, though not all. Check instructions before microwaving.
