Slow Cooker Minestrone Soup

This soup recipe is SO easy to make in the slow cooker or the Instant Pot (directions provided for both). If you don’t like buying extra appliances, no worries you can check out my stove top minestrone soup recipe. One thing I love about this soup, I puree the beans which thickens which is also great for picky eaters. Adding the rind from a wedge of parmesan or Romano cheese is my tip for adding extra flavor! I always stash them in my freezer just for soups, if you don’t have one toss some grated cheese into the soup while it’s cooking.

Helpful Cooking Tips

To keep the pasta al dente, I cook the pasta separate and add it to each bowl when I serve it, rather than throwing it in the soup which winds up soaking up all the broth. It’s totally your call, you can also just add the pasta to the soup at the end.

Freezer Directions

You can freeze leftovers for up to 3 months. Let it cool then transfer to freezer-safe containers.

Minestrone Soup Variations:

  • Swap the spinach for Swiss chard or baby kale.
  • To keep this low-carb, omit the pasta, you honestly won’t miss it with everything else in this soup.
  • Add some mini turkey meatballs, or even some sauteed crumbled turkey sausage.
