In a large pot, heat the olive oil over medium heat. Add the diced onion and minced garlic, sautéing until the onion is translucent, about 3-4 minutes.

Add the ground beef (or sausage) to the pot and cook until browned, breaking it apart with a wooden spoon, about 5-7 minutes.

Stir in the crushed tomatoes, chicken broth, Italian seasoning, salt, and pepper. Bring the mixture to a boil.

Once boiling, add the broken lasagna noodles and reduce the heat to a simmer. Cook for 10-12 minutes, or until the noodles are tender.

Ladle the soup into bowls and top each serving with a dollop of ricotta cheese, a sprinkle of mozzarella, and Parmesan cheese.

Garnish with fresh basil before serving. Enjoy your delicious one pot lasagna soup!
