Add olive oil to a large pot over medium heat. Add onion and saute until slightly translucent, about 3 minutes. Add in garlic and saute for an additional 5 minutes. Stir in sausage and cook until browned. Drain off excess grease as necessary.
Add broth, soup, diced tomatoes, tomato paste, oregano, black pepper, and Italian seasoning to pot. Bring mixture to a gentle boil, add lasagna noodles, and stir well. Cook soup for 8 to 10 minutes, or until noodles are tender.
Add Parmesan cheese and mozzarella and stir to combine. Divide soup into bowls and garnish with a spoonful of ricotta cheese and fresh basil. Enjoy!
