This easy Minestrone soup is packed up with lots of vegetables, tomatoes, beans, pasta, and flavored with Italian seasoning.

Minestrone in Italian means "thick soup". It is a thick soup that contains pasta, tomato broth, and vegetables. It can be vegetarian or non-vegetarian.

This Italian vegetable soup is absolutely delicious & is satisfying too. It has a perfect balance of veggies, pasta, and beans.

You can have this delicious hot soup on a cold day as lunch or dinner. It is a complete meal in itself. A new addition to our family's favorite dishes. My kids loved the soup.

The best part of this vegetarian minestrone soup is that there is no hard & fast rule about what veggies will go in it.

Feel free to use any vegetables or greens you have in your hand. It is a great way to use leftovers.

Cooking Tips

• Cook the pasta until al dente. Mushy or overcooked pasta will not taste good.
• The addition of vegetable broth enhances the flavor.
• Use any vegetable of your choice.
• Cook the vegetables in such a way that it should be cooked right. It should not be mushy in the soup.
• You can use any small shape pasta.
• I have used homemade tomato puree. You can also use a can of crushed tomatoes.
• If you are using canned red kidney beans, they are already cooked. You can use them straight away. But if you are using uncooked kidney beans then cook it & then use it. 
• To cook uncooked kidney beans - Soak them in water for 7 hours. Drain it & pressure cook for 5 whistles or more until it is cooked.
• If planning to freeze the soup then cook the pasta separately & then directly add it to the serving bowl.
• Do not freeze the soup with pasta. It will become mushy & spoil the entire soup when thawed.
• The soup will thicken with time. Add in some broth to adjust the consistency & reheat it.
• Garnish with parmesan cheese for more flavors (optional). If you are vegan then skip adding the cheese.

Variations that you can try

• You can add the vegetables of your choice. Add blanched bell peppers, corn, peas, potatoes, etc.
• If you are not vegan then add parmesan rind to the soup while cooking it. Or use vegan parmesan cheese.
• Make it gluten-free by using gluten-free pasta to make the soup.
• Garnish with some fresh basil leaves.
• If you are non-vegetarian then you can add meat to the soup. Use chicken broth instead of vegetable broth.
