    The Best Lunch Containers guide from a dietitian mom! Afterall, having the right lunch containers can be the answer to your school lunch struggles.

    Various colorful lunch containers with lids on a white surface.

    As kids get older, they eat more. This means that parents like you and I need to find ways to fit more food into their lunch boxes.

    While some kids won't mind eating a lot of one thing, I've noticed that most kids prefer eating a variety of foods for lunch. And with variety comes the need for more containers.

    As I mention in my lunch box for teens post, I think the key to staying motivated to pack lunches is to have the right kitchen tools and cookware at my fingertips... including lunch containers 😉

    Finding the Best Containers for School Lunches

    With so many options out there, it can be hard to find the right ones that will work for your kids, especially once they start eating more as they get into middle and high school.

    I'll help you narrow down your choices and figure out what to look for.

    What to Look for When Buying Containers for Packed Lunches

    • What food(s) that you often pack will you use it for? Yogurt? A sandwich? Chips or trail mix? Leftovers? There's no sense in buying containers that you won't use.
    • How much food will it hold? Food containers come in all shapes and sizes. So, while you'll want to be mindful of what containers will fit in the lunch box, you'll also want to consider how much food your kids will actually eat.
    • Will it fit in your child's lunch box? This is key. For instance, not all Bento Boxes and thermoses will fit in every lunch box.
    • Will it leak? This is also key. Choose leakproof containers especially when packing foods like yogurt, fruit salad, soup, and applesauce.

    My Picks for Best Lunch Containers

    1
    One teal colored Thermos Funtainer with a white plastic spoon leaning on the side of the container.
    My Insulated Jar Pick for Tweens and Younger Teens
    This is the insulated food jar my kids have been using for years. It's 10 ounces and keeps food warm or cold. It's lighter weight and smaller in size than the one Thermo Flask makes, which makes it perfectly sized for tweens.
    We've used this to pack all kinds of leftovers for school lunches, including bean and rice casserole, pesto tortellini, and more.

    One blue Hydro Flask insulated food jar.
    My Insulated Food Jar Pick for Teenagers
    My oldest daughter can't wait to pack her lunches with this! It holds more than the Thermos Funtainer she used to use and "looks more aesthetic" to her 😉

    One stainless steel sandwich container with a clear, see-through silicone lid.
    My Sandwich Container Pick
    This took over as my favorite container to use for packing sandwiches and wraps. It's very similar to the sandwich container from Pottery Barn Kids that I had been using for years, except it takes up less space in lunch boxes.
    In my experience, kids are more likely to eat their lunches when they can see what's packed. Love this container!

    Stainless steel lunch containers with different colored silicone lids. The box that the containers came in is in the back.
    My Stainless Steel Leakproof Lunch Container Pick
    We've been packing school lunches with these containers for a few years now. While you can't see what's inside of them, they are truly leak proof which is key for keeping lunch boxes clean. Perfect for packing fruit salad!

    Four plastic snack containers with screw top lids, each with a different color lid.
    My Plastic Snack Container Pick
    These are the containers I use when I pack yogurt from a tub in lunches for my kids. I also use them to pack trail mix, applesauce, fruit salad, pretzels, and dessert.

    Mini plastic dip containers with screw top lids.
    My Plastic Dip Container Pick
    These mini dip containers with a screw top lid are perfect for packing a small amount of guacamole, salsa, peanut butter, hummus, fruit dip, or salad dressing in school lunches.

    Dietitian Tips for Buying the Best Lunch Containers

    1. If possible, use containers that you can see through. Your kids will be more to open containers when they can see what is in it.
    2. Make sure they are sized so that they will fit in your child's lunch box. There is nothing like spending money on a bunch of lunch containers only to find out that they don't fit in their lunch box.
    3. Keep extra lunch containers on hand, especially if your kids pack lunches every day. You will be much more motivated to pack lunches if there are clean lunch containers handy. I don't know how many times I went to pack lunches only to find that all of our lunch containers were dirty (either my kids forgot to unpack their lunch, or I hadn't run the dishwasher yet🙃) So, now I keep extra lunch containers for school on hand.
    4. If all of your kids like packing leftovers for lunch, have one thermos for each kid handy. Some days I tell my teens, "Either you're having leftovers for lunch, or you can pack your own lunch" (#truth). 😆

    Questions You May Have

    Which containers are best for a lunch box?

    Food-safe containers that will hold the food you like to pack, that don't leak, and that will fit in your lunch box are what's best. My kids have different shaped lunch boxes, so I have to pack them differently.

    One of their lunch boxes doesn't hold as much as the other two, so I have to take that into consideration.

    How do you keep lunch containers from leaking?

    Read reviews of lunch containers before purchasing them. Food storage containers with a tight seal or with a screw top lid are often most leak-proof.

    How do you keep lunch containers cold?

    Use frozen ice packs when packing cold lunches.

    It also helps to rinse the inside of the thermos with ice cold water before putting the food you want to keep cold into the thermos.
