With the leaves turning brown and the weather cooling down, a Thermos food flask is an essential for enjoying your favourite hot meal wherever and whenever you need it……keeping you in control. Whether you're a busy professional, a student, an outdoor enthusiast, or simply someone who enjoys a hot meal during a long day, a food flask should be your daily accessory. 

During Autumn, our bodies naturally crave heartier and more nourishing foods to keep us energised and warm. In this post, we'll explore some of the best foods to put in your food flask at this time of year.

What can you put in a food flask? 

Thermos Food Flasks accommodate an array of culinary delights, both savoury and sweet. In this guide, we will explore the wide world of food flask possibilities, from hearty soups to a creamy risotto, you can enjoy your favourite home cooked meals on the go. 

So, let's dive in and discover the many delectable options that await inside your food flask and explore lunch ideas as well as practical tips to try this Autumn:

  • Vegetarian Burritos

Vegetarian burritos are not just delicious, but are pretty healthy because they're filled with beans, rice and veggies. The nutritional value is going to depend on the ingredients you add. One that will up the calorie count is sour cream, and there's little difference between store-bought dairy and vegan versions. 

These take a little time to prepare and are trickier to create in a small batch. So, a great idea to save some money is to have these in the evening and then simply use the leftovers in your food flask the following day.

  • Hearty Soups

Soups are an essential throughout the colder months and the perfect easy to prepare on the go meal. Whether you prefer classic tomato soup or a clear broth soup, we recommend using fresh or dried basil in tomato-based recipes or fresh parsley to add freshness to clear broth soups. 

A Thermos Food Flask is perfect for keeping your soup piping hot, all day long. Don't forget to include some crusty bread or crackers for dipping. We would recommend our Guardian Food Flask as it has a little compartment for storing croutons or bread for your soup! Check out our tomato, lentil & thyme soup recipe.

  • Chilli 

A hot bowl of chilli is like a warm hug on a cold day. The best part about a chilli is that it can be made vegan, vegetarian or with meat so it is suitable for everyone. Pop your chilli in your food flask and you're ready to go for the day! For a chilli with a twist, check out our chicken and peanut butter recipe. 

  • Stew and Braised Dishes

Autumn and winter are the perfect seasons for slow-cooked stews and braised dishes. Think beef stew, chicken casserole, or a vegetarian mushroom and lentil stew. These dishes are filled with flavour and only get better the slower they are cooked. For some Stew inspiration, check out our Irish lamb stew. 

  • Macaroni and Cheese

Indulge in a classic macaroni and cheese wherever you are. Perfect for the days you are in your office all day and need a filling and warm lunch to power you through the day. Add some breadcrumbs or bacon for an extra bit of crunch. Check out our macaroni and cheese recipe which has a splash of worcester sauce for extra flavour.

  • Risotto

A risotto is a healthy alternative for lunch compared to the cold supermarket meal deals. A homemade risotto is a delightful treat on a cold day. Choose your favourite ingredients, whether it's butternut squash, wild mushrooms, or seafood, and never have a boring lunch again. This is a great meal to fuel you for a gym workout. Check out our chicken & squash risotto recipe.

  • Protein Porridge

Never have time to eat breakfast before you go to work? Kickstart your day with a warm and healthy breakfast by preparing protein porridge in your food flask. Enjoy this once you arrive at work and it will still be hot. Add your favourite toppings like fresh berries, nuts, and a drizzle of honey for an extra dose of nutrition and warmth on cold early mornings. For all of those chocolate lovers, check out our protein porridge recipe.
