In a large pot or Dutch oven, brown the ground beef over medium-high heat. Drain any excess grease.
Add the chopped onion and minced garlic to the pot and cook until softened, about 3-5 minutes.
Stir in the crushed tomatoes, beef broth, oregano, and basil. Bring to a boil, then reduce heat and simmer for 15 minutes.
Add the broken lasagna noodles to the pot and cook until tender, about 8-10 minutes.
Stir in the ricotta cheese and parmesan cheese. Season with salt and pepper to taste.
Serve hot, garnished with fresh parsley.
Notes
This soup can be easily customized with your favorite lasagna ingredients. Add vegetables like bell peppers, mushrooms, or zucchini. For a spicier flavor, add a pinch of red pepper flakes.
