Lasagna soup has a delicious tomato base, with Italian sausage, beef, and tender lasagna noodles. Topped with an irresistible ricotta cheese mixture for the full flavors you love from the classic dish.
Add 1 tablespoon olive oil to soup pot. Heat over high heat. Once oil is hot, add 1 pound ground sirloin and 6 ounces bulk mild Italian sausage. Use spatula to break meat into small pieces. Cook without stirring until liquid evaporates and meat begins to sizzle in its own fat. Cook, stirring until meat begins to brown, approximately 7 minutes.
Add 1 cup finely chopped onion, 1 tablespoon garlic, 1 pinch crushed red pepper flakes, 1 teaspoon dried oregano, ½ teaspoon freshly cracked black pepper, and 1 teaspoon salt. Cook and stir until onions turn translucent in color, 3 to 4 minutes.
Carefully stir in 1 32-ounce can low sodium chicken broth, 24 ounces marinara sauce. Bring to simmer. Once mixture begins to simmer, reduce heat to medium low, simmer 45 minutes.
Add 12 ounces ricotta cheese, 3 ounces shredded mozzarella cheese, ½ cup finely grated Parmigiano-Reggiano cheese to large bowl. Stir until well combined. Set aside.
After soup has simmered for 45 minutes, increase heat to medium high. Stir in 8 lasagna noodles. Cook, stirring until pasta is tender, about 10 minutes. Reduce heat to low.
Ladle soup into desired serving bowls. Serve with one scoop of cheese mixture, sprinkle with torn fresh basil and Italian parsley, if desired.
