Lunch Box Packing Tips

  • Aim for balance. Not every single lunchbox has to be perfect, but do aim to include at least 2 components from the formula mentioned above.
  • Consider your child. Include at least one safe food that you know your child will eat. If they like their bread, veggies, etc. cut in a certain way, honor their preferences.
  • Get your child involved. This is something I’ve been working hard on lately. It’s so much easier for me to do everything by myself, but my toddler absolutely loves to help out in the kitchen.
  • Ask your child. Keep in mind though, you don’t want to give them too many choices. Offer just TWO choices from the same food group. For instance, “would you like pasta or bread? Banana or raspberries? Chicken or beans? They’re more likely to eat what they chose.
  • Try at home first. Try not to pack a completely new food as your child may find it intimidating.
  • Start serving dinner leftovers cold or at room temperature at home. This also includes foods that are normally eaten warm. You may be surprised to find that they taste fine without being reheated. With repeated exposure your child won’t have trouble eating them at school.
  • Don’t give up! There will be days when the lunch box you packed comes back hardly touched for whatever reason. Don’t panic or get upset. Rather, the best thing you can do is keep offering a variety of foods with their food preferences in mind. Your child will get the nutrients they need to grow and thrive over the course of days and weeks.

DIY Lunchables or Snack-Style Lunches

Some kids prefer grazing over eating one large meal—and that’s perfectly okay. A snack-style lunch is simply a balanced mix of smaller portions that still provides plenty of nutrition.

Build Your Own Snack Box

Choose:

Protein

Whole Grains

Fruit

Vegetables

  • Cucumbers
  • Bell peppers
  • Snap peas
  • Carrots
  • Edamame

Store-bought healthy snacks

There will be days when you rely heavily on packaged foods, and that’s perfectly OK! There is no shame in that! Here are the best store-bought snacks for kids.

Warm Thermos Lunch Ideas

A good food thermos opens up so many more lunch possibilities, especially during cooler months.

Pasta

Rice Bowls

Soups

Thermos Tip: Fill the thermos with boiling water for 5–10 minutes while you heat the food. Empty the water, dry the inside, then immediately add piping hot food. This helps keep lunch warm until lunchtime.

Favorite Lunch Boxes

The “best” lunch box really depends on your child’s age, appetite, and the kinds of foods you like to pack. Over the years, I’ve tested quite a few, and these are the ones I reach for again and again because they’re durable, practical, and make packing lunches so much easier.

Check out my guide to the best lunch boxes for toddlers, preschoolers, kindergarteners, and big kids, where I compare my favorites and share what each one is best for.

School Lunch Box FAQs

How do I keep my child’s lunch cold?

Use an insulated lunchbox along with 2 ice packs (place one on top and one on the bottom of the lunchbox). Packing refrigerated foods while they’re still cold and freezing items like yogurt tubes overnight can help keep everything at a safe temperature until lunchtime.

How do I keep food warm until lunch?

Use a high-quality insulated food thermos. Fill it with boiling water while you heat the food, let it sit for 5–10 minutes, then empty the water and immediately fill it with piping hot food. This helps meals stay warm for several hours.

My child is a picky eater. What should I pack for school?

Start with foods your child already enjoys and pair them with one new or less familiar food. Repeated, pressure-free exposure helps children become more comfortable trying new foods over time. It’s perfectly okay if lunches look repetitive! Familiar favorites often give kids the confidence to eat well at school.
