ingredients for vegetable noodle soup on a wooden board

Not only does the recipe require only one-pot and about 30 minutes to make, but it also requires very simple ingredients. Here are a few key components:

  • Mirepoix aka Onions, Carrots and Celery are the simple yet essential aromatic flavor base to start this dish off right.
  • Red pepper flakes: adds a very minimal yet perfectly balanced amount of heat. Feel free to add more as you prefer!
  • Potatoes: helps make this soup much heartier and filling.
  • Brown lentils: feel free to use any beans of choice if you do not have lentils or prefer not to use them.
  • Fresh thyme: add a burst of freshness and brighten up all of the flavors in this dish!
  • Bay leaves: the heat of the broth breaks down some of the more potent leaf flavors, and turns them into a gentler, pleasantly aromatic element.
  • Rotini pasta: or any other similarly sized pasta
  • Vegetable broth: learn how to make your own at home here!
  • Kale: we like to sneak greens in whenever we can–spinach works well here, too!
