Start by browning the meats. In a large skillet over medium-high heat, add the lean ground beef and ground Italian sausage. Cook for about 6-8 minutes, stirring frequently, until the meats are browned and no longer pink. Use a slotted spoon to drain and discard any excess grease, ensuring a rich, flavorful base for your Lasagna Soup.
Next, sauté the aromatics. In the same skillet, add a drizzle of olive oil and the diced yellow onion. Cook for about 4-5 minutes until the onion is soft and translucent. Then, add the minced garlic and continue to sauté for an additional 1-2 minutes, until fragrant. The warm aroma will fill your kitchen, setting the cozy mood for your Lasagna Soup.
Now it's time to build the flavors. Stir in the tomato paste, marinara sauce, and low sodium chicken broth, ensuring everything is well combined. Sprinkle in the salt, black pepper, red pepper flakes, dried oregano, and dried basil. Return the browned meats to the pot and bring the mixture to a gentle simmer, allowing the flavors to meld beautifully for about 10 minutes.
Cook the noodles next. Bring the soup to a rolling boil and add the broken lasagna noodles. Reduce the heat to medium and let the mixture simmer for about 8-10 minutes, stirring occasionally. As the noodles soften, they will absorb the flavors of the soup. If you’re using fresh spinach, add it in the last couple of minutes to keep its vibrant color and nutrients.
While the noodles cook, prepare the cheese mixture. In a separate bowl, combine the ricotta cheese, shredded mozzarella, and freshly grated parmesan cheese, stirring until well combined. This creamy concoction will be the final touch to your Lasagna Soup, enhancing its comforting profile.
Finally, it's time to serve. Ladle the hot and bubbly Lasagna Soup into bowls. Generously dollop the cheese mixture on top, allowing it to soften and melt into the soup. For a lovely finishing touch, garnish with fresh basil leaves. This delightful bowl of comfort is ready for your family to enjoy, bringing warmth and joy to your chilly evening!
