Containers to Keep Food Hot For Lunch

Containers to Keep Food Hot For Lunch

I work a construction job where my office usually consists of the cab of my truck, which means my lunch stays out in the truck, in the cold.  And when I say cold, I’m not talking about California ‘cold’, I’m talking about water bottle freezing cold (I lived in San Diego for eight years, I can make that joke).  The main problem is trying to find good containers to keep food hot for lunch.  I use a cooler which works great in the summer, not so much in the winter.  It does a much better job at keeping things cold than warm.

After trying a few other creative solutions and failing, I am realizing that I just need to buy better containers to keep my food hot until lunch, even in the coldest weather out in my truck.  So how do I keep lunch hot for hours without totally thrashing my bank account?

In the effort of researching how to keep lunch hot for hours, I have run across five top contender’s that all do a fantastic job of keeping my lunch hot for hours.

Thermos Stainless Steel King Food

Another Thermos titan, this stainless still jar would be the bigger daddy to its 10 ounce counterpart reviewed above. 24 ounces of space should satisfy most adult lunch appetites, if you are interested in eating only one thing and that one thing is more liquid than solid, which makes this the best soup type container on our list.  Unlike normal thermoses, this comes with a very large mouth which makes eating from it simple.

HotLogic Mini Personal Portable Oven

Here is an out of the box solution to keep your lunch warm.  It’s still a container, but also a portable oven.  This cool little device blew my nerd socks off, what an amazing idea!!  Its designed to either cook or keep your food warm.  There is a flat bottom heater that fits inside of the insulated back that can be plugged in.  It can be plugged in to your cars aux electric socket (using an inverter) or a plug in at work.  It is built with an aluminum lining that helps keep the heat in between transferring it from your house to the car to your work place.

I have an outside job where my lunch stays either in my car or the office trailer.  This is a perfect solution for me and I can just keep this plugged in and my lunch is always warm and ready to eat.

It was a bit smaller than the picture let on, but still able to store a decent sized lunch.  The beauty of this device is that you can plug it in a little before your lunch to start warming it up, cook it or just keep it plugged in through the morning to keep your lunch warm.  It currently comes in three different colors and is very easy to use.  Plug and Play!


  • 5 Star Rated!
  • Energy efficient design
  • UL CSA certified
  • Safely warms your meal
  • Good sealing system so your coworkers do not smell your lunch as it cooks/warms


  • Bag could be a little bigger.  Great one person lunch bag
  • Need a power outlet to take full advantage
  • The keyword ‘Oven’ is a little misleading, as it best heats up ‘pre-cooked’ meals


These are some of the best containers to keep food hot for lunch that we could find on the market.  Even if you don’t work a construction job, ensuring that you have a hot lunch on a cold day can make all the difference, even if you work in a cold office.  You could opt for the microwave, but who likes the rubbery texture that comes from nuking your food (well, I do actually kind of like that, but that’s not the point of this article!)?
