    This is the best minestrone soup that everyone in my family approves of, which doesn't happen too often! Now, I am not sure if this is an authentic Italian recipe, but I do know that it has all the flavors of a classic soup from one of my favorite restaurants in Canada. You may be more familiar with the Olive Garden version, but I think you will like this variation, too. If you enjoy this soup loaded with vegetables and flavor, you will want to try this Easy Vegetable Soup Recipe (One Pot) or Chicken Vegetable Soup (One Pot) as well.

    Key ingredients

    • Tomato paste- Adds the classic tomato flavor and thickens the base.
    • Parmesan cheese- This traditional Italian cheese pairs well with all the complimenting flavors.
    • Base- Water and vegetable broth are used for the foundation of this soup.
    • Vegetables- Use carrots, celery, zucchini, diced tomatoes, onion, spinach, and frozen green beans for a healthy combination of texture and flavor.
    • Spices and herbs- Include garlic, ginger, oregano, rosemary, Italian seasoning, bay leaf, salt, pepper for the perfect flavor profile.
    • Beans- Use canned (not dry) Red kidney beans and Northern beans.
    • Pasta- It's best to find a tubular kind such as Ditalini pasta or Rigatoni.

    Variations

    • Add in meat-You can add cooked ground beef, Shredded Chicken, meatballs, cooked sausage, or Ham pieces near the end to add more flavor.
    • Vegan version- Use vegetable broth instead of chicken broth.
    • Add different vegetables- Such as yellow squash, corn, tomatoes, or any of your favorites.
    • Spice it up- By adding red chili flakes or jalepenos for a little kick.
    • Creamy option- Stir in about 1 cup heavy cream or half and half in the last 5 minutes to make the soup thicker and creamier. You can also add cream of chicken soup, cream of celery soup, or cream of mushroom soup.
    • Gluten free version- Make this recipe as noted but use a gluten free pasta instead. Thankfully, there are many different options in local stores nowadays.

    How to make vegetarian minestrone

    1. Combine the following in the slow cooker- Diced tomatoes, tomato paste, parmesan cheese, vegetable broth, water, carrots, celery, onions, garlic, ginger, oregano, rosemary, Italian seasoning, bay leaf, salt, and pepper. and cook for a few hours.
    2. Let that cook for a few hours- Then, add kidney beans, northern beans, zucchini, and pasta and cook again until pasta is tender.
    3. Add spinach and green beans- And cook for a few more minutes then enjoy!

    Tips and techniques

    • Don't add the pasta till the very end- Or else they would over-cook and become very soft.
    • Add Beans and vegetables near the end- To prevent them from over-cooking and becoming too soft.
    • Don't replace dried beans with canned beans- Because they take very long to fully cook and you would have hard beans following this recipe's time table.
    • Use low sodium broth- Because you don't want the soup base to be too salty.
    • Herbs and spices can be adjusted- According to your personal preference.

      Do you cook the pasta or just throw it in the crockpot? Thanks!

        You just add the dry pasta and don't need to cook it first.

        Oh my! I think the pasta would become over-cooked. How did it turn out for you?

        Hi Ben! I usually chop up my leftover fresh herbs and put them in an ice cube tray. Then, I pour olive oil over them and freeze. Any time I need some fresh herbs in cooking, I take one cube out and use that. Hope this helps.
