[Lunch boxes are easy! ] Techniques and recipes for effectively using frozen side dishes

Making lunch boxes every day is time-consuming and difficult.
When you don't have time in the morning or can't fill up on one more item, frozen side dishes are recommended.

By using frozen side dishes, you can shorten cooking time and make making bento boxes easier.

We will introduce the points you need to know when using frozen side dishes, recommended recipes, how to make frozen rice balls that are convenient for making lunch boxes, and how to use commercially available frozen foods.

Tips for pre-made frozen side dishes

Lunch boxes are a great way to save on food costs and are good for your health, so many people make them by themselves.

By making and freezing meals when you have time or when ingredients are cheap, you can save yourself the trouble of cooking in the morning, which is also economically advantageous.

There are five key points to making well-prepared frozen side dishes.

1. Wrap tightly in plastic wrap to avoid exposure to air and freeze.
2. You can maintain good quality by freezing as quickly as possible.
3. Foods with a high water content are not suitable for freezing as the texture will change.
4. Food spoils easily in the summer, so when packing it in lunch boxes, use ice packs to prevent food poisoning.
5. For hygiene reasons, it is recommended to consume the food within about 2 weeks.

Just freezing it will reduce its deliciousness by half, so it is important to seal it tightly and freeze it as quickly as possible.

Also, by identifying foods that are not suitable for freezing and being careful about hygiene, you can use frozen side dishes without making mistakes.

Furthermore, there are some points that make standard frozen side dishes even more delicious.

Hamburger bento

The key is to cook it properly, as the texture will be bad if it is not cooked well. Cut into bite-sized pieces, wrap each serving in plastic wrap and freeze.

Cool the fried cutlet well, cut it into bite-sized pieces, wrap each serving in plastic wrap and freeze. Before putting it in the lunch box, toast it in the toaster to give it a crispy texture.

Neapolitan spaghetti

After cooking, remove from heat, pack into cups, wrap each in plastic wrap and freeze. When using it, it is important to warm it up properly in the microwave.

Recommended recipes for frozen side dishes

What kind of frozen side dishes are useful for making bento boxes? Here are some recommended recipes that are easy to make.

Tips for making frozen rice balls that you may not know about

Frozen rice balls are convenient when making bento boxes.
By making it when you have cooked a lot of rice or when you have leftover rice, you can easily use it when you need it.

There are some things to keep in mind when making frozen rice balls, so I'd like to take a look at them.

Rice wrapped in plastic wrap

Hold the cooked rice and add the ingredients. Wrap it in plastic wrap and let it cool, then put it in the freezer.

Rice in a freezer bag

Placing the rice balls in a storage bag such as a ziplock bag will prevent moisture from escaping and keep them from smelling like the freezer. It can be frozen for about 1 month.

When ready to use, thaw in the microwave while still wrapped in plastic wrap.
Starches such as rice turn into white wax when frozen, so be sure to thaw them by heating.

Ingredients suitable for freezing include pickled plums, kelp, salmon, salmon flakes, kelp tsukudani, and minced meat.

Basically, ingredients with low moisture content are recommended. Seasoned rice such as cooked rice and pilaf are also suitable for freezing.

On the other hand, unsuitable ingredients are tuna mayonnaise and salmon roe. Foods with a high moisture content and raw foods lose their flavor when frozen.

Additionally, rice balls sold at convenience stores can also be frozen. If you have any leftovers, put them in the freezer and use them effectively.

By the way, you can also freeze the bread you need to make sandwich lunches.

The storage method is very simple. Just wrap the bread in plastic wrap, put it in a storage bag, and freeze it.

Bread loses flavor and dries out as it approaches its expiration date, so storing it in the freezer will keep it delicious.

Frozen foods useful for making lunch boxes

Fried shrimp before frying

Making bento boxes will be easier by using commercially available frozen foods wisely.

Easy-to-use frozen foods with a rich repertoire are being developed one after another.

For example, it is a convenient product that can be eaten after being defrosted naturally, and can be simply taken out of the freezer and packed into a lunch box.

There are many side dishes that can be used as side dishes, such as simmered hijiki, kinpira burdock, ohitashi komatsuna, mapo eggplant, and green beans with sesame seeds.

There are also products that allow you to separate the tray and use as much as you want.

There are many side dishes on sale that can be used as main dishes, such as gratin, spring rolls, croquettes, shumai, and squid tempura.

Another advantage of frozen foods is that you can easily prepare dishes that would take time and effort to make by hand. Deep-fried foods are a staple of time-consuming dishes.

You can easily use it by heating fried foods such as fried chicken, croquettes, fried shrimp, and cutlets in the microwave or toaster.

The seasoning has also been carefully thought out so that you won't get tired of it. For example, various types of fried chicken are sold, including roasted sesame flavor, curry flavor, and tartar sauce flavor.

Furthermore, I would like to introduce some simple recipes that will allow you to make more effective use of frozen foods.

Easy oyakodon

Ingredients are fried chicken and green onions. Thaw the fried chicken and cut it into bite-sized pieces. Add the chopped green onions, mentsuyu, and sugar to a hot frying pan.

When it comes to a boil, add the fried chicken and beaten eggs and heat over medium heat for about 30 seconds. You can put it on top of rice to make oyakodon (oyakodon), and you can also put it in a cup and use it as a side dish.
