Heat a large pot over medium-high heat for 5 minutes. Flatten the ground beef into thin patties and place them directly into the pot. Cook undisturbed until browned on the bottom, 6-8 minutes. Flip and brown the other side.
Break the beef into bite-sized chunks. Add the onion and garlic; cook until the onions are translucent, 3-4 minutes.
Add the beef broth, crushed tomatoes, diced tomatoes, Italian seasoning, sugar, MSG, and black pepper. Bring to a simmer.
Add the noodles and cook until tender, 12-14 minutes (the time may vary depending on the pasta shape).
Stir in the cottage cheese, mozzarella, and Parmesan. Cook until heated through. Serve hot with more cheese and fresh basil (optional).
Notes
Preheat your pot before adding the beef to ensure proper browning.
You can drain any excess fat from the beef if you want before adding other ingredients.
Lasagna soup tastes better the second day after all the flavors have melded.
Storage
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. The pasta may absorb some liquid, so you might need to add more beef stock when reheating.
You can freeze the lasagna soup for up to 2 months, but the texture of the noodles may change slightly upon thawing and reheating.
