Chop the onion, carrots and celery into small pieces. Mince the garlic finely. Keep everything ready before cooking. This makes the process smooth and easy. Preparing ingredients first helps you stay relaxed while cooking.

Heat olive oil in a large soup pot over medium heat. Add the Italian sausage. Cook until browned and fully done. Break it into small pieces while cooking. Remove excess fat if needed, but keep some for flavor.

Add chopped onion, carrots and celery to the pot. Stir well with the sausage. Cook for five minutes until vegetables soften. Add minced garlic and cook for one more minute. The aroma will become rich and inviting.

Pour in diced tomatoes with their juice. Add chicken broth and stir gently. Sprinkle oregano and basil into the soup. Bring everything to a gentle boil. Reduce heat and let it simmer for fifteen minutes.

Stir in the cooked white beans and small pasta. Let the soup cook for ten more minutes. Stir occasionally so pasta does not stick. Taste and adjust salt and pepper as needed.

Turn off the heat once pasta is tender. Sprinkle fresh parsley on top. Add grated Parmesan cheese before serving. Ladle the soup into bowls while hot. Enjoy the warm and comforting flavors.
