Once the school year kicks off, the daily lunchbox grind is on. And it comes with some pressure. Sure, you want to pack something your child will actually eat, but you also want to make sure they get the nutrition they need to fuel a very active day. These two goals don't always go hand in hand. But with a little planning, you can absolutely create meals that are both kid-approved and nutrient-packed.

As a pediatric dietitian and a mom of four, my goal when packing lunches is for my kids to have the energy to focus in class, run around at recess, play sports after school, and enjoy time with their friends. The food we pack plays a big role in making that happen. A balanced lunch keeps kids energized, supports their growing bodies, and prevents the afternoon slump (and the inevitable hangry meltdown) that can happen when they haven't had the right foods. 

Fortunately, packing a nutritious lunch doesn't have to be complicated. I’m sharing my simple formula for building the perfect lunchbox that's balanced, satisfying, yummy, and realistic for busy families. I'll also review my favorite lunchboxes, including what I love about each one, so you'll have everything you need for the school year ahead. 

Start With Familiar Foods 

Before we get into my lunchbox formula, let’s start with the most important rule. The best lunch is one your child will actually eat. School lunch is not the time to test out a brand-new recipe, introduce a food they’ve never tried before, or pack something you hope they’ll like. When kids are at school, they’re navigating a busy day with distractions, limited time, and plenty of social pressure. The last thing you want is for them to open their lunchbox and feel unsure about what’s inside.

Instead, focus on foods your child already knows, enjoys, and feels comfortable eating. Familiar foods increase the chances that they’ll fuel their bodies during the school day (rather than coming home with a full lunchbox because they traded everything away to a friend!).

Focus on Nutritious Carbs 

Surprised to see carbs on this list? Don’t be! Carbohydrates usually get a bad reputation, but for kids, they’re one of the most important nutrients for fueling their busy days. Carbs are the body’s preferred source of energy, and growing kids need plenty of them to support their rapidly developing bodies, active play, learning, and everything in between. From running around the playground to concentrating in the classroom, kids are constantly using energy, and carbohydrates provide the fuel they need to keep going.

That said, not all carbohydrates are created equal. Focus on fiber-rich carbohydrates that provide more than just energy. Fiber balances blood sugar, keeps them fuller for longer, and supports digestion and gut health. In other words, choose carbs that work harder for your kiddo.

Examples: Whole wheat crackers, whole grain bread, brown rice, quinoa, whole wheat or legume pasta. 

Protein on Protein on Protein

Yes, we’re all a little obsessed with protein right now, and for good reason. Protein is an important part of a balanced lunchbox because it helps keep kids satisfied and provides the energy they need to make it through the school day. Staying fuller for longer stretches means  they’re less likely to come home starving or ask for a snack five minutes after finishing their meal. Protein also slows down the digestion of carbs to support more steady blood sugar levels and prevents the energy highs and crashes that can leave kids feeling tired or cranky. 

Examples: Cheese, yogurt, turkey slices, grilled chicken, nuts and seeds, beans, edamame,  hard-boiled eggs, tuna salad. 

Have Fun With Colorful Fruits and Veggies 

Fruits and veggies are one of the easiest ways to add fun, color, and variety to your child’s lunchbox. They’re also a sign that you’re packing a variety of important nutrients, including antioxidants, fiber, vitamins, and minerals. Plus, fruits and vegetables can help round out a lunch by adding natural sweetness and a satisfying crunch. Don’t feel limited to just fresh produce, either. Fresh fruits and veggies are great, but dried, freeze-dried, fruit and veggie pouches, and veggie chips can be convenient lunchbox-friendly choices, too. 

Examples: Apples, pears, bananas, berries, dried mango, raisins, celery, carrot chips, mini bell peppers, fruit and veggie pouches. 

Putting It All Together

Now that you have the building blocks for a balanced lunchbox, it’s time to put it all together. Start with a nutritious carbohydrate for energy, add a source of protein to keep them full, and include colorful fruits and veggies for fiber, vitamins, minerals, and variety. Lastly, don’t forget their water bottle to keep them hydrated throughout the day.

Here are a few examples of what a balanced lunchbox looks like:

• Whole grain sandwich with turkey + berries + cucumber slices  
• Hummus wrap with whole wheat tortilla + carrots + apple slices + cheese stick
• Pasta salad with whole wheat pasta and chickpeas and edamame + veggie chips + banana 
• Greek yogurt parfait with granola + berries + a hard-boiled egg
• Brown rice cakes + cheddar cheese slices + fruit and veggie pouch + trail mix
• Peanut butter (or sunflower butter) and jelly sandwich + mini yogurt pouch + mini  bell peppers
• Grilled chicken sandwich with whole wheat bun + sliced pear + carrots and ranch dressing 

The Best Lunchboxes to Pack In 

Once you’ve mastered what goes inside the lunchbox, the next step is choosing the right lunchbox to pack it all in. The best lunchbox keeps food fresh, is easy for kids to open independently, and is simple to wash at the end of the day. I’ve rounded up my favorite lunchboxes and shared what I love about each one, including their best features, what makes them stand out, and which types of kids they’re best suited for. Here are my top three picks:
