Step-by-Step Instructions

- Brown the meat. Heat olive oil in a skillet over medium heat. Add sausage, breaking it up as it cooks, until browned and cooked through.
Drain excess fat.
- Sauté aromatics. Add diced onion to the same pan and cook 3–4 minutes until softened. Stir in garlic and cook 30 seconds until fragrant.
- Load the slow cooker. Transfer sausage, onions, and garlic to the crockpot. Add crushed tomatoes, diced tomatoes, tomato paste, broth, Italian seasoning, basil, oregano, red pepper flakes (if using), bay leaf, and sugar.
Season with salt and pepper.
- Cook low and slow. Cover and cook on Low for 6–7 hours or on High for 3–4 hours to let the flavors develop.
- Add noodles. About 30 minutes before serving, stir in broken lasagna noodles. Cover and cook on High until noodles are tender, about 20–30 minutes. Stir once or twice to prevent clumping.
- Add greens (optional). Stir in spinach during the last 5 minutes until wilted.
- Make the cheese topping. In a small bowl, mix ricotta, half the mozzarella, and half the Parmesan with a pinch of salt and pepper.
This becomes your “lasagna” dollop.
- Finish and serve. Remove bay leaf. Taste and adjust seasoning. Ladle soup into bowls, top with a generous scoop of the ricotta mixture, sprinkle with remaining mozzarella and Parmesan, and garnish with fresh basil or parsley.
Storage Instructions
Why This is Good for You
- Protein-rich. The sausage or ground meat provides staying power, making this a satisfying meal.
- Lycopene boost. Tomato-based soups are a great source of lycopene, an antioxidant linked to heart health.
- Customizable veggies. Add spinach, zucchini, mushrooms, or bell peppers for extra fiber and micronutrients.
- Balanced comfort. A mix of carbs, fat, and protein keeps you full and cozy without being overly heavy.
What Not to Do
- Don’t add uncooked noodles too early. They’ll turn mushy and soak up too much broth. Add them in the last 20–30 minutes.
- Don’t skip browning the meat. Browning adds depth and prevents a greasy texture.
- Don’t forget to taste and season at the end. Slow cooking can mute flavors. A final pinch of salt or splash of broth brightens everything.
- Don’t overstuff the crockpot. Leave some headroom so the soup simmers evenly and doesn’t spill.
- Don’t mix the ricotta into the pot. Keep it as a topping so it stays creamy and doesn’t disappear into the broth.

FAQ
Can I cook the noodles separately?
Yes. Cook them on the stovetop until just shy of al dente, then add to the soup right before serving.
This helps avoid overcooked pasta, especially if you plan to store leftovers.
How do I keep the noodles from soaking up all the broth?
Add noodles near the end, and store leftovers without the pasta if possible. When reheating, add a bit of broth or water to loosen the soup.
Can I make this on the stovetop?
Absolutely. Brown the meat and sauté the aromatics, then add everything except the noodles.
Simmer for 25–30 minutes, add noodles, and cook until tender. Finish with the cheese topping.
What’s the best sausage to use?
Mild Italian sausage is classic, but hot Italian sausage adds a nice kick. If you prefer leaner options, use turkey sausage and boost flavor with a little extra Italian seasoning and garlic.
Can I use cottage cheese instead of ricotta?
Yes.
Blend it briefly in a food processor for a smoother texture, then mix with mozzarella and Parmesan as directed.
How can I make it lighter?
Use ground turkey, skip the mozzarella topping, and stir in extra spinach or zucchini. You’ll still get a cozy, satisfying bowl with less fat and calories.
What if my soup is too thick?
Add more broth, a half cup at a time, until it reaches your preferred consistency. Adjust salt and pepper after thinning.
Can I use no-boil lasagna noodles?
You can.
Break them into pieces and add them toward the end, checking for doneness a few minutes earlier since they soften fast.
