Most schools we know are nut-free now, ours included, which is a small thing until you realise how much of the easy lunchbox playbook (peanut butter, Nutella, anything with a “may contain” label) is suddenly off the table.

We rounded up the actual boxes worth buying last week. This is what actually goes inside one when nuts are off the menu, gathered from parents who’ve been doing this far longer than we have.

The peanut butter problem

Peanut butter does a lot of quiet work in a lunchbox: it’s protein-rich, filling and cheap. Holley Grainger’s nut-free lunch guide makes the point well: a nut-free classroom doesn’t mean giving up peanut butter, it means finding the seed-based versions that do the same job. Sunflower seed butter (sometimes sold as SunButter or soy butter) works as a like-for-like swap in almost any recipe that calls for peanut butter.

Savoury fillers worth batch-making

My Fussy Eater has built a genuinely useful stash of nut-free savoury bakes that freeze well, which matters more than any single recipe: ham and cheese muffins, mini egg lunchbox bites for kids who don’t love bread, and a nut-free pesto pasta made with seeds instead of pine nuts. All of these can go into the box straight from frozen in the morning and be properly defrosted by lunchtime.

For something that isn’t a sandwich at all, A Mind Full Mom’s nut-free lunch ideas, written by a parent with 18 years in nut-free classrooms, lean on DIY pizza Lunchables, bean burritos and quesadillas as reliable rotation staples that don’t feel like a compromise.

Sweet fillers that don’t rely on nuts

My Fussy Eater’s nut-free snacks roundup is worth bookmarking for the sweeter end of the box: chewy oat and rice krispie granola bars, banana breads with hidden courgette (they genuinely can’t tell), and jam pinwheels that only need three ingredients. None of these need a food processor or a special trip to the shop.

If your child is also a fussy eater

Nut-free and fussy-eater-friendly overlap more than you’d think, since both usually mean sticking to familiar, single-texture food. My Fussy Eater’s guide to lunchbox ideas for picky eaters suggests using bento tools to cut familiar food into fun shapes rather than introducing anything genuinely new, and packing dips separately so nothing touches anything else. Small, unglamorous changes, but they’re the ones that actually get eaten.

Before you pack anything

• Check your school’s exact policy, not just “nut-free.” Some schools ban all nuts and seeds, others allow seed-based spreads. A quick email saves a lunchbox coming home unopened.
• Read the label on anything shop-bought, including cereal bars and biscuits. “May contain nuts” rules a product out even if nuts aren’t a listed ingredient.
• Batch cook on a Sunday. Every source above leans on freezer-friendly bakes for exactly this reason: nut-free doesn’t have to mean more effort every single morning.
• Cut small round foods properly. Grapes, cherry tomatoes and similar need halving lengthways (quartered for younger children) as a choking-hazard precaution, regardless of any nut policy.

So what would I actually pack?

For a normal Tuesday: a ham and cheese muffin from the freezer, straight in the box.

For the sandwich-refuser: a mini DIY pizza Lunchable or a quesadilla, cut into fingers.

For the sweet tooth: an oat granola bar, made on Sunday, forgotten about by Wednesday.

Nut-free doesn’t have to mean boring. It just means the peanut butter jar stays at home.
