These 3 easy and budget-friendly meal prep ideas for bento prove that eating healthy can be delicious and fun! A little prep work on Sunday will set you up to eat healthier, save money, and reduce your stress through the week.
Many of us including myself struggle to prepare our children’s lunch. We want them to eat healthy homemade lunch at school, but how do we do that when our morning is hectic as it is?
A few hours on meal prepping for bento lunch box on a Sunday might be a solution to consider. Today I’ll show you an example of meal prepping and how I pack 3 days of bento using the ingredients I meal prep on a Sunday morning. As a bonus, I made it a challenge to make each bento box under $3.
How to Meal Prep Bento: $3 Bento Challenge
These 3 easy and budget-friendly meal prep ideas for bento prove that eating healthy can be delicious and fun! A little prep work on Sunday will set you up to eat healthier, save money, and reduce your stress through the week.
Plan Your Bento Schedule
Before the week start, plan your bento schedule and visualize what each bento should look like. If you’re new to bento making, you can even draw the bento box and write down each dish or ingredients in the section of bento. Eventually, you’ll be able to do this process in your head.
Planning ahead will help you check on the colors of ingredients so your bento won’t look dull with all the same color. It also helps cut down on frequent trips to grocery stores and save money by using the same ingredients for each bento.
Here’s my plan:
- Saturday – Shopping Day
- Sunday – the Meal Prep Day
- Monday – Bento #1: Karaage Bento
- Tuesday – Sandwich Day
- Wednesday – Bento #2: Soboro Bento
- Thursday – Sandwich Day
- Friday – Bento #3: Onigirazu Bento
On Sandwich Day, you can make your children’s favorite sandwiches (my kids love grilled cheese sandwich). I have some sandwich recipes here:
- Tamago Sando
- Wanpaku Sando
- Crispy Chicken Sandwich
- Katsu Sando (coming this Friday)
- Menchi Katsu Sandwich
- Korokke Sando
- Yakisoba Pan
Sunday – The Meal Prep Day
This is the most important day. I set aside 2-3 hours for meal prepping as you will need to make several dishes at the same time.
For the meal prep recipes and ideas I share on Just One Cookbook, I make sure they have a minimal/simplified ingredient list and cooking process (but it doesn’t mean less tasty!).
Here is the list of dishes I need for the week:
- Ajitsuke Tamago (Ramen Egg)
- Easy Carrot Salad
- Spinach Namul (Korean Spinach Side Dish)
- Chicken Karaage
- Chicken Soboro
- Scrambled Egg
- Tuna Salad
Other food to prepare:
- Wash vegetables (carrot, snow peas, spinach, green leaf lettuce, cherry tomato)
- Blanch snow peas
- Cook steamed rice (and freeze individual portions)
A Quick Breakdown of The Meal Prep Process
In general, I prepare EVERYTHING ahead of time, and this means the food that keeps well in the refrigerator. I cook and wash everything, and place each dish or ingredient in an airtight container (I use this brand) and put in the refrigerator. I even cook rice ahead of time and freeze the individual portions of the rice in a container.
In the morning of the day I pack bento, I reheat everything and let cool before I pack each dish into the bento box (Please read my Food Safety Tips for Bento).
To get everything ready in the most efficient way, I first separate my tasks into working stations and then tackle the tasks that require marinating/cooking or take the longest first, and I work backward from there.
*If you prefer to go through the process based on steps instead of working stations, please re-arrange the list I provided below to work best for you.
Washing Stations
- Rinse rice and soak for 20 minutes << Step 1
- Wash carrot, lettuce, tomatoes, snow peas, and spinach << Step 2

- Cook scrambled eggs << Step 17
- Deep (shallow) fry the Karaage << Step 18
Work Stations

- Make the Carrot Salad marinade and mix with julienned carrots << Step 10
- Make the Spinach Namul marinade and mix with blanched spinach << Step 11

Brilliant Bento Boxes…using ingrediences throughout each meal. They looked GREAT and DELICIOUS. Thanks so much for all that you share with all of us.
Hi Ruth, We are glad to hear you enjoyed Nami’s Bento post!
Happy cooking!
Thank you so much for these wonderful time and money saving bento recipes. Do you know of a good method for preparing the onigirazu without the plastic wrap?
Hi Jay! Thank you very much for reading Nami’s post and for your kind words!
You can use the parchment paper as a replacement.
We hope this works better for you!
I’m excited to try more things I’m discovering on your site! I have a couple questions, though: how much rice should I be preparing for all the bento lunches? What portions should I be freezing them in?
Hi Gigi! Thank you very much for reading Nami’s post!
The rice amount should depend on the size of your lunch/bento box and how you pack. If you are making Onigiri(rice ball) or Onigirazu, you need 1/3 cup of cooked rice for each one of those. Typically, 150g (3/4 US cup) of cooked rice is for one serving (for adults).
We hope this helps!
Even though the food is reheated and then cooled, it’d be consumed at least 2+ hours later for lunch. Is it safe to keep food at room temp for that long?
Hi w2soohoo! Thank you very much for reading Nami’s post!
For safety, we recommend using an ice pack to keep food fresh and safe till lunchtime.
