This minestrone recipe has been one of my family’s favorite soups for as long as I can remember! Filled with vegetables, beans, and pasta, it is naturally low in fat and oil free making it a hearty yet healthy vegan soup recipe.

This easy slow cooker soup recipe requires just a bit of chopping the veggies in the morning, then you can let it simmer away in the crock-pot until dinnertime.

A squeeze of lemon at the end adds a little acidity to make all the flavors pop, and then you’ll wilt in some fresh spinach just before serving so that it stays green and vibrant rather than disintegrating into the soup.

Tips For Your Best Minestrone Soup

  • Change up the veggies: The ingredients for this Italian minestrone soup can be changed up with the seasons using what is available. Add other seasonal veggies such as corn, potatoes, winter squash, peas, parsnips, cabbage, kale, etc. Use frozen veggies when applicable.
  • Make it gluten-free: Use gluten free pasta for a gluten free minestrone soup.
  • Vary up the herbs: Change up the herbs using fresh or dried. Herbs such as Italian seasoning and herbs de provence are great. Individual herbs, dried or fresh, you can use include: oregano, basil, thyme, marjoram and parsley. Basil is a popular herb for minestrone.
  • Add vegan sausage: Toss in some vegan sausage, diced or sliced for extra hardiness and protein.
  • Cook the pasta separate, if it’s cooked in with the soup it becomes mushy and extremely unpleasant. For best results, cook the pasta ahead of time or 30 minutes before the soup is ready. You’ll be very happy to have firm pasta instead of mush!

How To Store Leftovers

  • Refrigerator: Leftovers can be kept for 5 – 6 days in a covered container in the refrigerator.
  • Freezer: This soup is freezer-friendly and freezes well for 2 – 3 months. To freeze, let cool completely and store in freezer-safe containers (affiliate link), leaving 1/2 inch head space for expansion. Let thaw before reheating. You can also freeze larger portions in large ziplock bags or containers.
  • Reheat: Simply re-warm on the stovetop over low heat until warmed through. Alternately, reheat in the microwave using 30-second intervals, stirring after each, until warm. It makes a great meal prep for the week with homemade vegan cornbreadno knead bread, or naan on the side for soaking up the juices.

Serving Suggestions

I like to garnish my soup with parsley, a squeeze of lemon and twist of fresh cracked pepper. Here are a few of my favorite sides:

  1. Amazing veggie packed soup. I have made this a few times now, I did not change a thing except I didn’t have a bay leaf, and I also added in fresh basil and oregano instead of dried. Absolutely delicious!!! I used the PC Beefless Broth and I can’t get enough, I just made a big batch so I can freeze some on those lazy days. Thank you for sharing! So simple and a great way to use up all the garden veggies. ( I also don’t use pasta all the time, I add in fresh Kale instead)…super yummy <3

  2. Why does the Cook Time say 3 hours when down below it says On High 4-5 hours, on On Low 7-8 hours?

    1. Julie | The Simple Veganista says:

      Thank you for pointing that out, Ellen! Must have been a typo. I’ve updated the recipe card with 5 hours of cooking time. Enjoy!

    2. Christopher says:

      This soup looks delicious! I want to try it. I am wondering if the spinach is diced or put in the soup as is? Thank you so much.

      1. Julie | The Simple Veganista says:

        Great question, Christopher! I added the spinach as is, but you could also give a good rough chop before adding it to the soup. Hope that helps. Enjoy!

  3. Catherine says:

    Hi! Do you sautee the onions, carrots & celery a little first before adding to crock pot?

    1. Julie | The Simple Veganista says:

      No, generally, slow cooker recipes just add everything to the pot and cook – it’s a dump and cook, set it and forget it style of cooking. No fussing with sauteeing, but you can saute the onion, carrots, and celery beforehand if you prefer. There really are no set rules! Enjoy the soup, Catherine!
