Whether you didn't have time to eat your overnight oats for breakfast or you're trying to eat healthier or cheaper work lunches by bringing your own, there's likely a food thermos designed to meet your needs. Food thermoses, also called food jars or soup thermoses, are typically vacuum-sealed, insulated food containers that keep your food warm or cold at food-safe temperatures for several hours—without the aid of electricity or microwaves. Plus, many are designed to prevent leaks (so you can bring soups to work) and resist significant denting when dropped, making food thermoses ideal for on-the-go lifestyles.

But there is a lot of variety among brands when it comes to how well each food thermos performs and meets your specific needs. Here, we've compiled the top food thermoses available on the market.

What to Look for in a Hot Food Thermos

Size: Thermoses come in a wide range of sizes. To choose the best one to fit your needs, consider the quantity of food and/or beverages you want to carry, as well as how you’ll be carrying it. For example, if you want to use it in a lunchbox, you’ll want a smaller size, while if you want it to hold a whole pot of coffee, you’ll need something bigger.

Features: Beyond keeping your drinks hot and cold, some thermoses boast features that may make them especially convenient to use. Some come in sets that can be stacked, while others contain multiple small compartments to hold various foods at the same time. Certain models also come with built-in utensils. Think about what features would benefit you.

Style: If you eat lunch at work or your kid takes one to the school cafeteria, you may want to consider style when selecting a thermos. Some are basic stainless steel, but others come in an array of fun colors and prints. Beyond that, certain models also come rubber details that look cool and make them more durable.
