1-First Step: Brown the meat and aromatics. Heat a skillet over medium heat. Add 1 lb ground beef or Italian sausage, breaking it up as it cooks until browned, about 5-7 minutes. Stir in 1 diced onion and 3 minced garlic cloves. Cook for 2-3 more minutes until softened and fragrant. Drain excess fat. This builds flavor layers right from the start. For vegan adaptations, use plant-based meat here.

2-Second Step: Load the slow cooker. Transfer the browned mixture to a 6-quart slow cooker. Add 1 (28-oz) can crushed tomatoes, 1 (15-oz) can tomato sauce, 4 cups beef broth, 1 tbsp Italian seasoning, 1 tsp salt, and ½ tsp pepper. Break 8 oz lasagna noodles into 1-2 inch pieces and add them. Stir everything well to combine. Use vegetable broth for lighter versions or gluten-free noodles as needed.

3-Third Step: Cook low and slow. Cover and cook on low for 6-8 hours or high for 3-4 hours. The slow cooker lasagna soup with noodles needs time for flavors to meld and noodles to tenderize. Check noodles at the lower end of time; extend if firm. Stir halfway if your model allows to prevent sticking. This hands-off method suits busy schedules perfectly.

4-Fourth Step: Add the cheeses. In the last 30 minutes, stir in 1 cup ricotta cheese and 2 cups shredded mozzarella. Replace lid and let melt. For low-calorie options, use part-skim cheeses. Taste and adjust salt or pepper. The cheese creates that signature lasagna creaminess in soup form.

5-Final Step: Serve and garnish. Ladle into bowls. Top with chopped fresh basil and extra cheese. Serves 6-8 with 15 minutes prep. Pair with crusty bread. Total time fits any day. Leftovers store well, as covered later.
