This slow cooker minestrone soup is packed with fresh veggies, beans and seasonings. Pop everything in your slow cooker and come home to a warm and comforting meal.
As soon as the weather cools, I’m all about soups and slow cooker meals, especially this slow cooker minestrone soup.
It’s flavorful and filling thanks to all the herbs, hearty vegetables and protein-rich beans. Many minestrone soups are made with pasta, but not this one! I skipped the noodles for more beans, which I prefer because they add a lot more protein and fiber to this soup.

Why You’ll Love This Soup
- Effortless – The slow cooker does all the work for you. Just prep the ingredients, add them to your slow cooker and let the magic happen! It’s the perfect meal for busy days.
- Meal prep – One pot makes a lot of soup so you can meal prep the soup over the weekend to enjoy for lunch or dinner during the week.
- Protein-packed – One serving of this soup is loaded with over 20 grams of plant-based protein thanks to all the beans making this a great vegetarian dinner option.
Ingredients Needed
- olive oil – used to sauté the vegetables before adding them to the slow cooker, which adds a nice flavor.
- vegetables – you’ll need carrots, yellow onion, garlic, celery, cabbage, potatoes and zucchini for this soup.
- diced tomatoes – I used canned regular diced tomatoes, but you can use fire roasted diced tomatoes if you want some added flavor.
- beans – we’re using a mix of red kidney, garbanzo and white beans. All canned, drained, and rinsed, these add plenty of protein and texture.
- chicken or vegetable broth – this forms the liquid foundation of the soup, adding depth and richness. You can choose based on your dietary preference.
- parmesan cheese – fresh Parmesan cheese is great as a topping. And, as a bonus secret ingredient that will add a ton of flavor, you can toss a parmesan rind into the soup at the same time you add the other seasonings and spices.
- seasonings and spices – you’ll need fresh parsley, dried basil, dried oregano and a bay leaf for that Italian flavor. Plus, you can’t forget about the salt and pepper to bring all the flavors together!
Minestrone Variations
- Add spice: For those who like a little heat, add a small dish of red pepper flakes to your soup.
- Dairy-free: Make this soup dairy free by skipping the parmesan rind and the extra parmesan for topping or try using a dairy-free or vegan parmesan.
- Add grains: Make this soup heartier by adding in cooked rice or pasta before serving. Check out my classic minestrone soup for a version with noodles!
- Use what you have: This is a great “clean out the fridge” soup! Have different vegetables you want to get rid of? Throw them in! This is delicious with added leafy greens (like kale or spinach) or even green beans.
How to Make Slow Cooker Minestrone Soup
I’ve said it before, but I love slow cooker meals because they are so easy to make and this minestrone soup recipe is no different. Here’s how to make it:
Step 1: Start by sautéing the carrots, onion, celery and garlic before adding them to the slow cooker, just for additional flavor. My slow cooker base is stove-top friendly, which makes the transition from stove-top to slow cooker a breeze.
Step 2: Next, simply add the sautéed vegetables and all remaining ingredients into the slow cooker. Cook on high for 4 hours or low for 6-8 hours or until the potatoes are cooked. Taste the soup before serving and season with additional salt and pepper as needed. Remove the parmesan rind and bay leaf. Portion the soup into bowls, top with parmesan cheese and enjoy!
Recipe Tip!
The ingredients, especially the potatoes and cabbage, may absorb some of the broth as they sit. So, when you’re ready to enjoy the leftovers, you might need to add a bit more broth or water to bring the soup back to your desired consistency.
What to Serve with Minestrone Soup
This soup is a filling meal on it’s own thanks to all of the veggies and beans, but if you’re looking for some sides to serve with this soup here are some ideas:
- Bread: Serve your minestrone with a side of fresh bread (like sourdough). The combination of warm soup ad crusty bread is a classic and comforting choice.
- Crackers: For more crunch try serving this soup with your favorite crackers. These almond crackers would be delicious!
- Croutons: Croutons are the perfect crunchy addition to minestrone. Use store-bought or try my sourdough croutons.
- Salad: You can’t go wrong with a soup + salad combo! Try this garlicky kale salad, Italian chopped salad or simple kale salad for some greens.
Storing Leftovers
Like I mentioned earlier, soup is perfect for meal prep because you can make a large quantity and enjoy it over several days.
After cooking, allow the minestrone soup to cool slightly, then store it in an airtight container in the refrigerator for 4-5 days. For longer storage, let the soup cool completely then add to a freezer-safe container and store in the freezer for up to 3 months. To thaw, let it defrost in the fridge overnight.
