1-First Step: Preparation and Mise en Place Start by gathering all your ingredients to ensure a smooth cooking process. Dice your onion finely so it will meld seamlessly into the soup. Mince the garlic cloves to release their aromatic oils. Measure out all your seasonings, sauces, and liquids beforehand. This preparation might seem like an extra step, but it makes the actual assembly process much faster. If you’re using regular lasagna noodles, break them into bite-sized pieces now. Breaking them into pieces about 1-2 inches in size works well. Having everything prepped and measured before you start cooking is the secret to stress-free meal preparation and will make this easy lasagna soup even simpler to assemble.

2-Second Step: Browning the Meat In a large skillet over medium-high heat, brown your 1 lb of ground beef or Italian sausage. Break it up with a spoon as it cooks to ensure even browning. This step takes about 5-7 minutes. Once the meat is browned, if there’s excessive grease, you may drain some of it, though a small amount adds flavor to the soup. During the last 2 minutes of cooking the meat, add your diced onion and minced garlic to the skillet. This technique allows the aromatics to soften slightly and begin releasing their flavors. Cooking the onions and garlic with the meat infuses them with meaty goodness that will distribute throughout the entire soup.

3-Third Step: Assembling the Soup Base Transfer the browned meat, onion, and garlic mixture to your slow cooker. Add the 28 oz of crushed tomatoes, 15 oz of tomato sauce, 4 cups of beef broth, and 2 tbsp of tomato paste. These liquids form the foundation of your soup and will slowly meld together during cooking. Add your seasonings: 1 tbsp of Italian seasoning, 1 tsp of salt, and 1/2 tsp of pepper. Give everything a good stir to combine all the ingredients thoroughly. At this point, your slow cooker should be about 2/3 to 3/4 full, which is the ideal level for slow cooking.

4-Fourth Step: Slow Cooking to Perfection Cover your slow cooker and set it to cook on LOW for 6-8 hours. This longer, gentler cooking method allows the flavors to develop fully and creates a rich, complex taste. The low temperature prevents the tomatoes from becoming too acidic and gives the meat time to become perfectly tender. If you’re short on time, you can cook on HIGH for 3-4 hours, though the flavor development won’t be quite as pronounced as with the longer method. Avoid removing the lid frequently during cooking, as this releases heat and can significantly extend the cooking time.

5-Fifth Step: Adding the Pasta During the last 30 minutes of cooking, add the broken lasagna noodles to the slow cooker. Stir them gently to ensure they’re submerged in the liquid. This timing is crucial because pasta can become mushy if cooked too long in a slow cooker. If possible, give the noodles a gentle stir halfway through this final 30 minutes to prevent them from sticking together. This simple step helps ensure even cooking and prevents clumping. The pasta should be al dente (tender but still slightly firm to the bite) when the cooking time is complete.

6-Final Step: Finishing and Serving Once the noodles are cooked to your liking, it’s time to finish your Slow Cooker Lasagna Soup. Ladle the hot soup into bowls and top each serving with a generous dollop of ricotta cheese. The heat of the soup will slightly melt the ricotta, creating creamy pockets throughout the bowl. Sprinkle shredded mozzarella and grated Parmesan over the ricotta. The mozzarella will melt beautifully, creating those coveted cheese pulls that make lasagna so satisfying. Finally, garnish with fresh basil leaves for a pop of color and fresh flavor. Serve immediately while hot, and enjoy the compliments from your family or guests!
