SLOW COOKER VEGETABLE SOUP

Healthy, but warm and hearty Vegetable Soup is a delicious vegetarian, gluten free soup that is prepared in the Slow Cooker. The smell of classic homemade Soup complete with herbs and veggies, is one of the most comforting smells in a kitchen.

The key to a good soup is a long and slow simmer, and that is where our Slow Cooker or Crock Pot comes in very handy.

HOW TO MAKE VEGETABLE SOUP IN THE SLOW COOKER

In around 10 minutes, you can chop the vegetables and fill up your slow cooker. You can also sub in whatever frozen or fresh vegetables you have on hand.

The slow simmer gives veggies time to infuse and meld together to create a soup that has plenty of flavor, plus quarts of leftover soup to pack for lunches or put away in the freezer. 

  • First, start with sautéing the onions, carrots, and celery with some garlic; then, transfer to the pot of your slow cooker.
  • Add potatoes, tomatoes, tomato paste, green beans, herbs, spices and broth to the slow cooker; stir everything together.
  • Cover and set Slow Cooker on LOW for 6 hours, or set on HIGH for 3 hours.
  • Stir in some corn the last 30 minutes of cooking, and you’re pretty much DONE! 🙌

TIPS FOR MAKING THE BEST VEGETABLE SOUP

  • I almost always use frozen green beans and frozen corn for this soup. It’s just easier for me because I have numerous bags of frozen veggies in the freezer. THUS, do not be afraid to use frozen veggies. Just dump them in the slow cooker and go about your bizness. 
  • The key to a flavorful soup is adding fresh herbs and acid just before serving. For this soup, stir in chopped fresh parsley or dill, and add a squeeze of lemon juice.
  • While I serve this Vegetable Soup as a starter, to make this more of a main dish, stir in some leftover shredded chicken before reheating. Or have chicken on the side served over brown rice pilaf.

      This soup was amazing. I did change a few things, however:

      – one cup of chicken broth in place of the eighth cup of vegetable broth because I ran out of the vegetable broth.
      – added a tad more of the spices
      – added a bit more corn (yummy!)

      My husband, who is picky when it comes to vegetables, absolutely loved this soup. It’s now going to be a staple for these cooler months.

      I am so ready for cooler weather when it’s acceptable to have soup cooking in the slow cooker every day! This soup reminds me of my childhood, however, I can’t wait to make this in my slow cooker.
