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 will keep for 5 – 6 days in the refrigerator, stored in a covered container.
  • Freezer: This soup is freezer friendly and freezes well for up to 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. I made this recipe for the first time 4 weeks ago and it was a hit. I have made it every week since then as I LOVE to have it on hand for meals. It’s the best minestrone I’ve ever had and I’ll be making it for the rest of my life!

  2. Great recipe, delicious on a cold fall or winter day with some nice bread. One thing, the cooking time, above the ingredients list says that the cooking time is 3 hours, however this is definitely at least a 4 hour recipe as mentioned later in the recipe.

  3. Silvia L Kantor says:

    Absolutely delicious! My husband and I thoroughly enjoyed it!

    1. Julie | The Simple Veganista says:

      Thanks for sharing, Silvia – so glad you both enjoyed the recipe! Cheers :)

  4. So easy! I’ve noticed that so many veg slow cooker recipes require cooking the veggies before putting them in the crock pot… For me, it just defeats the purpose and I might as well make it on the stove in those instances. But this recipe lets you throw everything right in (except the pasta) and go about your day. I followed the recipe pretty much to a T, except I used kale instead of spinach because that’s what we had on hand. Thank you so much for this recipe! This will be a regular meal at our house.

  5. Great soup, and so easy! We loved it, thanks!

  6. Julie | The Simple Veganista says:

    Thanks for sharing, Christina! I’ve updated the recipe to add the bay leaves, and I’ve added an extra hour overall to the cooking times!

  7. Christina says:

    The flavor of the soup was good. I love all the veggies. Great tip to cook the pasta separately. Next time I will make it in a Dutch oven so I can sauté the carrot, onion, and celery. I had the soup in the crockpot for 4 hours on high and those veggies did not seem to cook down enough for me.

    The bay leaves- I noticed that they are in the blog post, but not the ingredient list! Almost forgot them!

  8. Do you have the measurement for each serving?

    1. Julie | The Simple Veganista says:

      Hi Lisa, I never measured but I would guess about 1 + 1/2 cups for the 6 servings per the nutritional card.
