Best Insulated Thermoses for Keeping Soups and Food Hot (or Cold!)

At Thrive Cuisine, we work hard to make you the best recommendations on food & appliances in the kitchen. One of the ways we support ourselves is by getting a small commission on some purchases made through our links at no cost to our readers.

Bringing your own lunch to work is a great way to save money and have greater control over the food you eat. Let's face it though, the food is never as good as when it was first prepped. The process of cooling and reheating ruins all original texture and flavor. The key is to keep it warm all day without exposing it to air. That's why we put together this list of the best insulated thermoses for soups and hot food!

Why Did We Select These Particular Food Flask Thermoses?

In our other article about the best thermoses for keeping coffee hot, we talk about thermoses designed specifically for coffee or some soups. These thermoses are small and thin - designed to fit into a cup holder, yet still heavily insulated. Food thermoses tend to be wider, making them more appropriate for using a utensil to eat out of them. We've selected a range of thermos sizes for this round-up so you can find what works best for your food warming and storage needs. Obviously, they are all reasonably small enough to take to an office or on a camping trip.

What Can You Store in These Thermoses?

While we already mentioned soup, there are a lot more choices that these food flasks would be good for. Here are some ideas to spark your creativity:

  • Fruits
  • Smoothies
  • Pasta Dishes
  • Rice Dishes
  • Salads

The list is pretty much endless. If you have the right food thermos, you can enjoy your favorite foods no matter where you're going.
