Heat olive oil in a large pot over medium heat. Add ground beef and cook until browned, about 5-7 minutes. Add the onion and garlic, sauté until the onion is translucent, about 3 minutes.
Stir in oregano, basil, and crushed red pepper flakes. Add crushed tomatoes and chicken broth; bring to a boil.
Reduce heat to a simmer and add the lasagna noodles. Cook until the noodles are tender, about 10-12 minutes.
In a small bowl, mix ricotta and Parmesan cheese. Season with salt and pepper to taste.
To serve, place a dollop of the cheese mixture in each bowl, ladle the soup over, and top with mozzarella. Garnish with fresh basil.
