In a large pot or Dutch oven, heat a drizzle of oil over medium heat. Add the ground beef (or sausage) and cook until browned, breaking it apart with a spatula. Drain excess fat if necessary.
Add the diced onion to the pot and sauté until translucent, about 3-4 minutes. Stir in the minced garlic and cook for another minute until fragrant.
Pour in the crushed tomatoes and broth, then stir in the dried basil and oregano. Season with salt and pepper. Bring the mixture to a simmer.
Once simmering, add the broken lasagna noodles. Cook according to the package directions, usually around 8-10 minutes, until the noodles are al dente.
In a separate bowl, combine the ricotta cheese, heavy cream, and half of the mozzarella and Parmesan cheeses. Mix until well-combined.
Once the noodles are cooked, stir in the ricotta mixture until fully incorporated and creamy. Heat through, but do not let it boil.
Taste and adjust seasoning if necessary.
Serve the creamy lasagna soup hot in bowls, topped with the remaining mozzarella and Parmesan cheeses and garnished with fresh basil leaves.
Notes
Feel free to substitute ground beef with Italian sausage for added flavor.
