Can You Pack Meatballs for Lunch at School?

Absolutely! Leftover meatballs are one of my favorite hot lunches because they reheat well and stay warm inside a thermos. If you already have homemade meatballs in the fridge or keep frozen meatballs in the freezer, you’re halfway to lunch! While I usually pack meatballs hot in a thermos, they’re also delicious at room temperature, making them an easy lunch no matter how your kids like to eat them.

Making It for Lunch

Heat the thermos
If you’re packing a hot lunch, fill a food thermos with boiling water, close the lid, and let it sit for 5 minutes while you heat the meatballs.
Warm up the meatballs
Heat 4 to 6 meatballs with your favorite marinara sauce until they’re piping hot. Keeping the meatballs coated in sauce helps them stay moist and keep a nice texture.

If you’re packing them at room temperature, there’s no need to heat them up piping hot, just warmed, to take the chill away.
Pack it for lunch
For a hot lunch, empty the thermos and immediately fill it with the hot meatballs and sauce. Close the lid.

For a room-temperature lunch, pack the meatballs in a leak-proof lunch container. Pack fruit, veggies, or bread on the side.

Laura’s School Lunch Packing Tips

Can I use frozen meatballs?

Absolutely. Frozen meatballs are one of my favorite shortcuts for packing lunch. Heat them until they’re piping hot before adding them to the thermos, or let them cool if you’re packing them at room temperature.

Do I have to use marinara sauce?

Not at all. Marinara is a classic choice, but barbecue sauce is also great. My son loves sweet and sour meatballs, and the tender slow cooker meatballs with gravy, or your favorite baked meatballs, all work with this packing method.

Do I really need to preheat the thermos?

If you’re packing a hot lunch, yes. Preheating the thermos helps keep the meatballs hot until lunchtime and only takes about 5 minutes. Watch this video to learn how.

More Ways to Make Lunch Easier

Cook once, eat twice! That's my secret to effortless school lunches. Leftover spaghetti and pizza slices make easy, next-day meals. Or toss extra taco night ingredients into a container for a quick and delicious burrito bowl. If you’re looking for more hot lunches made from leftovers, here are a few more ideas to try.
