Heat a large pot over medium heat and add olive oil. Once shimmering, add the chopped onion and cook until translucent and fragrant, about 5 minutes.
Add the minced garlic to the pot and cook for about 1 minute, stirring constantly until fragrant, avoiding burning.
Stir in the crushed tomatoes, chicken broth, dried basil, and oregano. Bring the mixture to a gentle simmer, allowing the flavors to meld for 10 minutes.
Once the broth is flavorful, add the uncooked pasta and cook until al dente, following pasta package instructions, about 8-10 minutes.
Stir in the shredded mozzarella and grated parmesan cheese until melted and creamy, about 2 minutes. Taste and season with salt and pepper as needed.
Serve the hot lasagna soup garnished with additional parmesan or fresh herbs if desired.
