10 Best Lunch Boxes 2023 | UK Chef Reviewed

Preparing a packed lunch means you won't be tempted by a meal deal every time you walk past the supermarket! To make sure you stick to home-cooked food though, you're going to need something that'll protect your lunch and keep it hot (or cold) and fresh until you're ready to eat. Or, you might be after a cute and sturdy box for kids that'll stay secure in your child's backpack on the way to school. 


Whatever the reason, it's essential to find a container that meets your requirements in terms of size, material, compartments, and budget. To help you decide on the right one, we've compiled a list of our favourites to buy at Amazon and John Lewis. Whether you'd prefer an insulated stainless steel flask set for adults, a kid-friendly plastic tub with a matching bag, or an eco-friendly glass container for meal prep, we've got options aplenty! Moreover, we have partnered with chef Ryan Yen for reviewing and fact-checking the article to deliver you the best information.

How to Choose a Lunch Box in the UK

Key Points to Consider
  1. Consider the Types of Food and Temperature When Selecting a Material
  2. Choose an Insulated Lunch Box to Keep Your Food Hot or Cold for Extended Periods
1

Choose the Material Based on Your Lifestyle, and the Temperature and Types of Food You’re Storing

Choose the Material Based on Your Lifestyle, and the Temperature and Types of Food You’re Storing

If You’re Looking for Something to Save Time, Opt For a Durable Plastic That Is Microwave and Dishwasher Safe

Plastic is a durable material that's usually suitable for use in both microwaves and dishwashers, so it's an excellent choice if you like to take leftovers to work or school but don't fancy scrubbing away at the sink afterwards. 


As it's also very lightweight, it won't make your bag too heavy - even if you like to bring several meals' worth of food or snacks with you on your travels! Just make sure that the lunch box you select is made from BPA-free plastic, to ensure that it won't contain potential toxins and is safe to eat from.

If You Need Something to Keep Your Food Cool in the Summer, Go For Sturdy Stainless Steel or Metal

Lunch boxes made from a metal like stainless steel are great at keeping your snacks cool until lunchtime; they're a real life-saver in the summer for food like salads and fruit! They're also much sturdier than other materials, so will survive even a long day of travelling.


However, this type of container is not suitable for use in the microwave - you'll need to opt for a different, non-conducive material if you want to reheat leftovers, or go for an insulated metal food flask instead.


For convenience, you can always have layered thermal lunch box to put different components to have a balanced meal throughout your day. For example, a 3 to 4 layer thermal lunch box can easily fit soup, salad, rice or noodles with a main and sometimes fruit for extra space.

For Storing Strong-Smelling Foods, Glass Works Best as It Is Non Porous and Microwave and Dishwasher Safe

Glass is an eco-friendly material that's safe to use in both the microwave and the dishwasher, as well as a traditional oven. Plus, it's non-porous and therefore isn't affected by whatever food you plan to store inside it (whereas plastic can become stained over time or may absorb food odours).


Unfortunately though, glass is heavy and breakable so we don't recommend it as an option for children or anyone who plans to take their lunch on a long hiking trip! It's also not as common as plastic or metal.

Make Sure You Pick an Insulated Lunch Box if You Need to Keep Your Food Hot or Cold for Long Periods

Make Sure You Pick an Insulated Lunch Box if You Need to Keep Your Food Hot or Cold for Long Periods

No microwave or refrigerator when you're away from home? No problem! An insulated container will keep your lunch hot or cold for several hours, until you're ready to dig in - some can even last for 12 hours! Whilst it might be a little bulky in comparison to a regular lunch box, we're certain that the convenience factor means that you won't mind it taking up extra space in your bag.

This premium quality food flask by Chilly's is sturdy and looks super stylish. It keeps the contents hot for 4 hours and cold for 5 hours - no matter what time of day you feel like eating, your food will be fresh and ready to devour!


Whilst this container is a little on the expensive side, we think it's definitely worth the investment - especially as it's leak-proof, sweat-proof, and lightweight enough to carry round all day. It also comes in a larger size (500ml) if you need a bigger meal!

Leak-Proof Glass Lunch Box Thats Microwave, Oven, Dishwasher and Freezer Safe

With this leakproof glass tub by Lock & Lock, it's never been easier to heat up last night's dinner! As well as being microwave-proof, this tub is suitable for use in the oven, dishwasher, and freezer. It can withstand temperatures up to 400 degrees Celsius and you can eat straight from it once you've reheated your leftovers.


The only downside to this lunch box is that the glass makes it heavy so it's not ideal for carrying around all day. Still, at less than a tenner, it's a low-priced eco-friendly option that's well worth considering.

Bento-Style Box Featuring Dividers, Perfect for Keeping Your Lunch Cold

The simple, bento-style layout of this box by Mepal is ideal for those who like to have a mix of different foods at lunchtime or post-gym. Use the divider to keep snacks separate or remove it to make space for a sandwich - the choice is yours! When it comes to clean-up time, just pop it all in the dishwasher and relax.


We think this is a great product for any occasion that requires cold food - work, school, or even picnics. During the winter months though, you may prefer something with insulation instead to keep your meal nice and warm.

Cute Unicorn Lunch Set Including a Sandwich Tub, a Matching Bag and a Flask

Looking for a cute lunch set that's designed for kids? This charming Pusheen sandwich tub comes with a matching bag and flask, so you can rest assured that your little one will have everything they need at lunchtime. There's even space on the backpack for you to write their name, which means they should remember to bring it home too!


Sadly this set isn't suitable for dishwasher use, but all of the parts (including the bag) are easy to wipe clean. It may not be the cheapest or most robust option on our list, we think this is a good quality product that kids will enjoy using every day.

Although we love the chic, minimalist design of this product, there are other containers in our ranking that are more affordable and can keep food hot/cold for much longer. Still, if you want something that looks unique, this is a good shout!

A Compact Container Complete With Dividers, Perfect for Sarnies and Snacks

This lunch box by Joseph Joseph is all about saving space - it has a large base compartment for sandwiches as well as a top compartment with a divider for snacks. Once you've finished munching, simply pop the top compartment into the base to make the box smaller. It's suitable for microwave and dishwasher use too.


While this container has a silicone lid, it's not completely leakproof so we don't advise storing wet food inside. It's also a little pricey compared to some of our other picks which are cheaper and won't leak.

If your little one loves dinosaurs then you can't go wrong with this unique lunch box by Suck UK! The eye-catching T-Rex shaped container not only looks good but it's heavy-duty, microwave-friendly, and makes getting ready for school fun.


Sure, this is a bit of a curveball option and it won't appeal to everyone, especially those who would prefer something a bit less garish. It holds plenty of snacks though, and it's easy to carry thanks to the elasticated handle.
