How To Make Bento お弁当の作り方

  • Have fun packing lunches with my comprehensive guide on How To Make Bento Boxes! Whether you’re making school lunches for your little ones or work lunches for yourself, bento boxes help you plan and pack a healthy and colorful meal. Plenty of tips and tools here for you to get started.

    Tutorial of how to make bento.

    Many of Just One Cookbook readers have asked me to write a post about how to make bento since last year. I was hesitant at first because bento making is not something I specialized in, and there are so many great bento blogs out there that feature elaborate bentos that I wish to have for my lunch.

    However, I continue to receive requests from readers so I’ve decided to share how I make everyday bentos (not a fancy one!) for my children.

    I also included my very first video in this post! 🙂

    Useful Tips & Tools on Packing Bento Boxes

    I grew up eating mom’s homemade bento in school, and I even help packed my brother’s and my own bento in the morning with my mom when I was in high school (I was actually a morning person decades ago). My mom taught me the basic bento rule of thumb and I still follow the same guideline, which I will show you in this post.

    For your information, I make bento that can be all consumed in 10 minutes by my 5-year-old daughter and 7-year-old son.

    This bento post is to show you some ideas and tips that may be helpful for you to pack homemade lunches in a bento box. I’ll also talk about the food safety for bento packing and some of the side dishes you can pack for bento. Food does NOT have to be Japanese food. You can pack your own meals in the bento box based on the guidelines below. Also, please adjust your bento box size and amount of food you put according to your needs.

    Now let’s begin!

    What You Need:

    1. Bento Box (Lunch Box)

    It doesn’t have to be a Japanese bento box. You will need some sort of container or lunch box to put your food in. I use thermal lunch boxes for warm food like pasta and grilled cheese sandwiches.

    I also find it convenient when an ice pack is already attached to the bento box lid to keep food safe (read more about food safety tips for bento here).

    2. Silicone Cups

    The silicone cups are great for keeping wet things away from dry things and holding loose items like blueberries in one place. Usually, silicone cups come in bright and cheerful colors which improves the presentation for bento. They are reusable and come in many different sizes and colors.

    3. Dividers

    The silicone dividers come in bright colors to improve the presentation for the bento and they help separate one food from the other without mixing up the flavors. You can also use edible separators such as lettuce, shiso leaves, cucumber slices, etc.

    4. Colorful Picks

    The picks come in many shapes, patterns, and colors and some picks are really playful and cute (like my little panda picks below)! They are helpful to put small foods together (like meatballs and berries) and also add extra color to your bento. Children are more likely to become interested in eating foods with those picks.

    5. Sauce Containers

    The sauce containers help you store the sauce separately so that the food will stay dry until lunchtime. It’s not so pleasant when the sauce ends up getting mixed up with foods it’s not meant for.

    Bento Making Rules of Thumb:

    Now that you have a bento box ready, let’s go over the basic rule of thumb on bento making!

    Tutorial of how to make bento.

    Rule 1: Divide the Meal Proportionally

    Dividing the meal proportionally will help you assemble a nutritiously balanced meal. It should at least have 4 types of food: carbs (carbohydrates), proteins, vegetables, and fruits. Be conscious about what types of foods to put in bento box when you are packing lunch.

    Tutorial of how to make bento.

    My children’s bento ratio is 4 : 2 : 1 : 1 (4 parts carbs : 2 parts proteins : 1 part vegetables : 1 part fruits). I sometimes pack 2 parts of veggies inside the bento (skip fruit section) and prepare a separate container just for fruits.

    Rule 2: Keep in Mind to Add Colors

    When making choices of which foods to include in the bento box, choose bold colors to provide visual impact. Not only do colorful vegetables and fruits add beautiful colors, but they are often the healthiest.

    If I have similarly colored dishes like broccoli and asparagus, I separate them and put other foods in between to make the bento more visually appealing. Sprinkling colorful furikake (rice seasonings) or garnishing with chopped parsley and green onion gives nice accents to the overall presentation.

    1. Red

    Tomato, carrot, red radish, bell pepper, apple, grapes, strawberries, plum, raspberries, nectarines, etc.

    2. Yellow & Orange

    Corn, sweet potatoes, pumpkin, bell pepper, orange, lemon, banana, etc.

    3. Green

    Lettuce, cucumber, green onion, edamame, broccoli, spinach, okra, shiso, snap peas, asparagus, parsley, bok choy, green beans, Brussels sprouts, green peas, kiwi, etc.

    4. White, Black, and Brown

    Daikon radish, potato, onion, lotus root, enoki mushroom, white sesame seeds, blueberries, shiitake mushroom, gobo (burdock root), wakame (dried seaweed), nori (dried seaweed sheet), hijiki (dried seaweed), black sesame seeds, etc.

    Rule 3: Pack the Foods Tightly

    It’s important to pack the foods tightly to prevent the food from shifting in the bento box. You don’t want to see messy bento when you (or your children) open the bento box at lunchtime. Try packing in the following order.

    1. Pack pre-shaped or bulky food first.
    2. Then put more flexible-shape food in remaining spaces.
    3. Finally, add some small accent food like cherry tomatoes and steamed broccoli to fill in the small gaps to prevent from shifting.

    Now Let’s Pack Bento!

    Tutorial of how to make bento.

    Step 1: Put Carbs

    I usually fill 1/2 of the bento box with carbs. Of course, you can pack brown rice, pasta, wraps, sandwich, bread, etc instead of white rice.

    Tutorial of how to make bento.

    Step 2: Put Proteins

    Any kind of beef, chicken, pork, tofu, beans, eggs, or other protein sources can be packed in 1/4 of the bento box. If possible, add 2 kinds of protein dishes in the spot.

    Tutorial of how to make bento.

    Step 3: Put Vegetables and Fruits

    Vegetables and fruits should be filled up in the remaining 1/4 of the bento box. Packing at least 2 kinds of vegetable dishes is ideal. If you have more vegetable dishes, pack the fruits in a separate container.

    5 Helpful Tips

    Now how can you improve your bento making? Here are some helpful tips to make a tastier bento quickly!

    Tip 1: Use Pre-Cooked Meals to Save Time

    If you want to pack bento quickly, use leftovers from previous dinner and a stash of frozen precooked meals. When I make bento-friendly menus, I always make a big batch of food, reserve a portion or two for that week, then freeze individual portions for later use. All I need to do in the morning is to re-heat pre-portioned food and pack into the bento. If you really want to make things easy, you can also pre-cut fresh veggies and fruits, cook a big batch of rice, and make many other dishes ahead of time.

    Tip 2: Keep Dry Foods Dry

    To make sure not to spoil foods easily, separate wet foods from dry foods to keep them from getting soggy and unappetizing. Always drain sauce/dressing before packing into the bento box. If you like to add some sauce, put on top of shredded cabbage/lettuce and put the food on top to avoid from spilling. You can also use a sauce container and pour it at mealtime.

    Tip 3: Use Different Texture and Flavors

    Eating different texture and flavor of foods will increase more appetite. If the main dish is seasoned with a soy sauce base, avoid adding other similar flavor dish and try putting refreshing veggies instead.

    Also, keep in mind that food at room temperature tastes better when the food has more flavor. Use extra seasoning for bento portion or make the sauce more concentrated before taking away for bento portion.

    Tip 4: Reheat and Cool Down Food Completely

    Food safety is especially important for bento.  Always remember to wash your hands and use clean utensils when you touch food.  I highly recommend you to re-heat the food before packing, and cool down the food completely before closing the bento.  And don’t forget to keep ice packs in a lunch bag!  To read more about Food Safety Tips for Bento, click HERE.

    Tip 5: Plan Ahead

    I know, for some people including myself, “planning ahead” can be hard. But once you get the hang of it, planning actually helps you save time and money, and you will always be more prepared despite your busy schedule.

    You just need to take 15-30 minutes of your time during the week and figure out what you have in the refrigerator, what you will be cooking throughout the week, and what you will need from grocery stores.

    A friend of mine in Japan uses a meal planner to organize her dinner and bento menus. I adapted hers and made a simplified Bento Calendar. With this calendar, you can visually plan out your weekly dinners and bento menus. If you would like a copy, please click HERE.

    Final Thoughts

    Honestly speaking, packing bento does take longer than packing a sandwich and it’s more work than eating out. Why do we go through extra steps when our life is already busy?

    I believe bento is much healthier overall and it’s less expensive than eating out. But most of all, I want to brighten my children’s day with colorful, cute bento. They look forward to their lunchtime, just like how I used to look forward to my mom’s homemade bento. And it only requires a little bit of time and effort to make bento once you get used to making bento.

    I also hope this Japanese bento culture and technique will improve your eating habit to stay healthy and make everyone’s lunchtime more fun. Thank you for reading!
