Veggie Mac and Cheese Lunch

This veggie mac and cheese is a delicious hot meal your kids can enjoy from school, thanks to a thermos container! It’s such a cozy option for cold days and a yummy switch from the usual sandwiches, wraps, and bentos. It’s also a yummy way to include vegetables in your child’s school lunch.

Since it includes pasta and a creamy cheese broth, it also makes a more appealing way to serve veggies in this tasty winter lunch.

Of course, you can swap out the ones in this recipe for any chopped veggies you know your child would prefer. Frozen green peas, diced zucchini, red bell pepper, and chopped tomatoes are all great options.

Boxed or Homemade Mac and Cheese Soup for Lunch

Since we all love homemade mac and cheese and the boxed mix, I’ve included directions on how to make this cozy soup with both. 

It’s pretty simple, prepare the mac and cheese according to directions, add the extra liquid and frozen veggies, and simmer until everything is thickened and heated through. Easy!

How to pack Mac and Cheese in a Thermos 

There’s a way to keep food hot in a thermos for hours, and below I share step-by-step directions on how to do that with this cheesy soup:

  1. Preheat the thermos container with boiling water. This step is optional, but it helps.
  2. Heat the soup in the microwave or stovetop to a piping-hot temperature.
  3. Drain the water from the thermos.
  4. Fill the thermos with the very hot soup.
  5. Close the thermos container and pack it inside a lunch bag.

    I was wondering what thermos containers you use. They look like they have a really wide opening and that seems really convenient. Thanks!

    I have made this twice and I am having the same problem a couple of other commenters have had with the cheese not breaking down in the broth. It just sticks to everything. We love the flavor but the texture of the cheese in it is weird. Is there something I could do different?

      another solution is to leave the cheese for the end and sprinkle it on top. It won’t be creamy-cheesy but still delicious -and you use less cheese.
