📖 Substitutions & Variations
- Seafood Lasagna Soup: Substitute sausage with shrimp, crab, or diced fish. Add these towards the end of cooking to prevent overcooking and maintain a fresh seafood flavor.
- Vegetarian Lasagna Soup: Replace the sausage with plant-based crumbles or sautéed mushrooms for a hearty alternative. Use vegetable broth instead of chicken broth for a fully vegetarian version.
- Low-Carb Option: Replace lasagna noodles with zucchini or eggplant slices. Slice them thinly and add them to the soup during the simmering stage for a keto-friendly version.
🔪 How To Make Spicy Lasagna Soup
Step One: In a large pot add the oil, onions, and peppers and cook over medium to high heat, for 4-5 minutes until the veggies start to soften a little.
Step Two: Add the garlic and sausage to the pot, stir, and cook until the sausage is browned.
Step Three: Once the sausage is browned and crumbled up add the oregano, Italian seasoning, tomato paste, crushed tomatoes with juice, chicken broth, milk, and water. Stir until everything is mixed together very well.
Step Four: Bring the mixture to a boil and then add your broken lasagna noodles. Turn to low heat and simmer to cook the noodles until done, around 10 minutes. Make sure to stir here and there so no noodles stick. Once done add the mozzarella in and stir. Ladle the soup into bowls and top with extra mozzarella, parmesan, and fresh parsley.
