🍱 What’s in This Bento

Everything in this bento is either a leftover from the previous day or a staple in the fridge.

Mapo tofu
Steamed rice (Underneath the mapo tofu)
Stir-fried cabbage
Cherry tomato and edamame

Prepping & Leftovers

The mapo tofu and stir-fried cabbage were all leftovers from dinner the day before.
I always keep frozen rice on hand and microwave a portion in the morning.
Cherry tomatoes and edamame are quick and easy ways to add color and freshness to any bento.

How to Pack Bento: Step-by-Step

Here’s the plan: Spread the rice in the bento box, then top it with a generous portion of mapo tofu and some stir-fried cabbage.

Step 1

Reheat leftovers, then let them cool completely before packing to avoid condensation and spoilage.

Step 2

Place the rice into the bento box and top it with mapo tofu, covering about two-thirds of the space. (I added a nori sheet on the rice, but that’s optional.)

Step 3

Add the stir-fried cabbage to the remaining open space.

Step 4

Place the edamame and cherry tomato next to the cabbage.

Packing Tips

Bento is usually packed in the morning and eaten later at the office or school. Since it sits at room temperature for several hours, it’s important to pack it in a way that keeps the food safe and fresh, especially during hot weather. Here are some simple tips to help!

Reheat leftovers thoroughly to kill any bacteria that could cause spoilage.
Cool all items completely before sealing the bento box to prevent condensation and reduce the risk of bacterial growth.
Be sure to pat dry any moisture from washed cherry tomatoes or thawed edamame with a paper towel before packing.
If you prefer to prevent mapo tofu flavors from soaking into the rice, you can add a layer on top of the rice, like a sheet of nori, a sprinkle of furikake, or shiso leaves.

Bento Carrying Tips

Once everything is packed, wrap your bento and chopsticks in a cloth—it’s not only handy for carrying, but can also be used as a placemat when it’s time to eat.

If you’re packing the bento during warm weather and it will sit at room temperature for several hours, be sure to use an ice pack (you can find cute ones at Daiso, a 100 yen shop) or an insulated lunch bag to keep it fresh and safe.
