The best part about any soup is that you can easily customize the veggies with what you like or have on hand – so feel free to change things up.

I used small pasta shells to bulk things up even more.

The secret to keep the pasta not soggy is by adding it 30 minutes before you’re going to serve the soup and cook on HIGH.

If you plan on freezing this soup, I would leave out the pasta and cook it separately on the stove whenever you’re planning to serve it. That way, the pasta doesn’t end up getting soggy.

HOW TO MAKE THE BEST SLOW COOKER MINESTRONE SOUP

  1. Start off by chopping all of your vegetables. Soup is a great way to get rid of any leftover veggies you have in your fridge as well. Or, if you’re in a pinch, your local grocery store may also sell pre-chopped veggies just for soup.
  2. In a large 6 quart slow cooker, add carrots, celery, garlic, onions, basil, oregano, rosemary, thyme, diced tomatoes, tomato paste and bay leaves.

  3. Stir in vegetable broth and water (use less if you like it less watery) into the slow cooker and season with salt and pepper to taste. Cover with lid and cook on HIGH for 2-3 hours or LOW for 5-6 hours (time varies according to your slow cooker – adjust times as needed).

  4. Stir in spinach and season with more salt and pepper as needed and stir in balsamic vinegar (if using) and serve warm with bread and top with parmesan cheese and garnish with parsley if desired.

***NOTE about pasta – **If you plan to freeze this or serve the next day, leave out the pasta and cook on the side and then combine when you are ready to enjoy. This helps the pasta not get soggy.

IS HOMEMADE MINESTRONE SOUP FREEZER FRIENDLY?

Yes! If you plan to freeze or serve this soup the next day, leave out the pasta and cook in a separate pot. Then once you’re ready to eat, reheat the soup on the stove on low then add the pasta when you are ready to enjoy. Reheating the pasta before you serve the soup helps the pasta not get soggy.

IS HOMEMADE MINESTRONE SOUP HEALTHY?

This soup is packed with a ton of vegetables and legumes and contains tons of vitamins, protein and fiber. It’s also vegan and gluten free if you use a gluten free pasta.

CAN I HAVE MINESTRONE SOUP IF I AM FOLLOWING A PALEO OR LOW CARB / KETO DIET?

To make this minestrone soup low carb, keto and paleo friendly, leave out the pasta, beans and carrots and add cauliflower and green beans instead.

CAN I MAKE MINESTRONE SOUP AHEAD OF TIME OR FOR MEAL PREP?

  • Chop the veggies the day before and store in an airtight container or zip-top bags in the fridge
  • If using dried beans instead of canned, cook and drain ahead of time and store in an airtight container in the fridge
  • Leave out the pasta if freezing this and only add the pasta if you plan on enjoying this on the same day

Minestrone Soup is a sure way to keep you warm and cozy which is perfect if you are feeling under the weather.

Serve it with some crusty bread, a sprinkle of Parmesan and just grab a spoon!

Instructions

FOR THE SLOW COOKER VERSION:

  1. In a large 6 quart slow cooker, add carrots, celery, garlic, onions, basil, oregano, rosemary, thyme, diced tomatoes, tomato paste and bay leaves. Stir in vegetable broth and water (use less if you like it less watery) into the slow cooker and season with salt and pepper to taste. Cover with lid and cook on HIGH for 2-3 hours or LOW for 5-6 hours (time varies according to your slow cooker - adjust times as needed)

  2. 20-30 minutes before serving, stir in kidney beans, cannellini beans, zucchini and pasta and cook on HIGH until pasta is tender.**(SEE NOTE below on freezing)

  3. Stir in spinach and season with more salt and pepper as needed and stir in balsamic vinegar (if using) and serve warm with bread and top with parmesan cheese and garnish with parsley if desired.

  4. ***NOTE about pasta - **If you plan to freeze this or serve the next day, leave out the pasta and cook on the side and then combine when you are ready to enjoy. This helps the pasta not get soggy.

FOR THE STOVETOP VERSION:

  1. In a large heavy bottomed pot or dutch oven, heat olive oil over medium heat.

  2. Add carrots, onion, celery, garlic, and onion and saute for about 4 minutes, or until vegetables are slightly softened.

  3. Add basil, oregano, rosemary, thyme and cook for an additional 1 minute. Add the tomato paste, bay leaves, vegetable broth, water, zucchini and both of the beans.

(***you can also cook the pasta directly with the soup but this soaks up more water so you may have to add more water. Just add the pasta after simmering for 20 minutes, then bring to a boil and allow to cook for another 8-10 minutes or until pasta is tender)

  6. Season with more salt and pepper as needed and stir in balsamic vinegar (if using) and serve warm with bread and top with Parmesan cheese and garnish with parsley if desired.

That varies by what's inside the slow cooker and also by the appliance's setting and model, the experts say. Most recipes for all-day cooking call for 6 to 8 hours on low. Quality- (and safety-) wise, another 1 to 2 hours in 'keep warm' mode won't mess things up.

What to use to make soup thicker? ›
