What You’ll Need
- 1 pound ground Italian sausage (mild or hot) or ground turkey/beef
- 1 small onion, diced
- 3–4 garlic cloves, minced
- 4 cups low-sodium chicken or vegetable broth
- 1 (28-ounce) can crushed tomatoes
- 1 (14.5-ounce) can diced tomatoes (fire-roasted if you like a smoky note)
- 2 tablespoons tomato paste
- 2 teaspoons Italian seasoning
- 1 teaspoon dried basil (optional but nice)
- 1 teaspoon fennel seeds (optional, adds classic sausage-lasaña flavor)
- 1 bay leaf
- 1 teaspoon kosher salt, plus more to taste
- 1/2 teaspoon black pepper
- 2 cups baby spinach or chopped kale
- 8–10 lasagna noodles, broken into pieces (or 8 ounces of short pasta)
- 1/2 cup heavy cream or half-and-half (optional, for a creamy finish)
- 1 cup ricotta cheese
- 1 cup shredded mozzarella
- 1/2 cup grated Parmesan, plus more for topping
- Fresh basil or parsley, chopped, for garnish
- Olive oil, for browning
Step-by-Step Instructions
- Brown the meat: In a skillet over medium heat, warm a splash of olive oil. Add the sausage and break it up as it cooks.
When browned, add onion and sauté until soft, then stir in garlic for 30 seconds. Drain excess fat.
- Load the slow cooker: Add the browned meat mixture to the crockpot. Pour in broth, crushed tomatoes, diced tomatoes, and tomato paste.
Stir in Italian seasoning, basil, fennel seeds, bay leaf, salt, and pepper.
- Cook low and slow: Cover and cook on Low for 6–7 hours or High for 3–4 hours. Taste and adjust seasoning if needed.
- Add the noodles: About 30 minutes before serving, stir in the broken lasagna noodles. Keep the lid on and cook until the noodles are al dente.
Add more broth if the soup thickens too much.
- Make the cheese topping: In a small bowl, mix ricotta, mozzarella, and Parmesan with a pinch of salt and pepper. This becomes your “lasagna” dollop.
- Finish the soup: Stir in spinach and cream (if using) during the last 5–10 minutes until greens are wilted and the soup looks silky.
- Serve: Ladle into bowls and top each with a generous scoop of the cheese mixture. Garnish with fresh basil or parsley and extra Parmesan.
How to Store
- Fridge: Store in airtight containers for up to 4 days.
Keep extra broth on hand to loosen the soup if it thickens.
- Freezer: For best texture, freeze the soup without noodles for up to 3 months. Add fresh noodles when reheating.
- Reheat: Warm gently on the stovetop or in the microwave. Add a splash of broth or water to adjust consistency and top with fresh cheese mixture.
Health Benefits
- Protein-packed: Sausage or lean ground turkey provides staying power and helps keep you full.
- Lycopene-rich tomatoes: Tomatoes bring antioxidants that support heart health.
- Leafy greens: Spinach or kale adds iron, folate, and fiber without changing the flavor much.
- Customizable dairy: Ricotta and mozzarella add calcium and creaminess.
You can lighten it up with part-skim cheeses or dairy-free alternatives.
- Portion-friendly: Because it’s a soup, it’s naturally satisfying with fewer calories per bowl compared to layered lasagna.
Pitfalls to Watch Out For
- Overcooked noodles: Add them only in the last 20–30 minutes. They soften quickly and keep cooking in hot soup.
- Too thick or too thin: If it thickens, add broth. If it feels watery, let it simmer with the lid slightly ajar, or add a little extra tomato paste.
- Not enough seasoning: Taste the broth before adding noodles.
Adjust salt, pepper, and herbs so the flavors pop.
- Greasy soup: Drain the meat well. If needed, skim excess fat from the top before serving.
- Dairy curdling: Stir in cream at the end on low heat. Boiling after adding dairy can cause separation.
Recipe Variations
- Turkey or chicken version: Use ground turkey or chicken and chicken broth for a lighter take.
Add extra fennel and Italian seasoning for depth.
- Vegetarian: Skip the meat and add mushrooms, zucchini, and bell peppers. Use vegetable broth and consider a can of white beans for protein.
- Gluten-free: Choose gluten-free lasagna noodles or short gluten-free pasta. Cook time may vary; check for doneness earlier.
- Spicy kick: Use hot Italian sausage and a pinch of red pepper flakes.
Fire-roasted tomatoes add a smoky edge.
- Extra creamy: Stir in more cream or a dollop of mascarpone at the end. Top with a little extra mozzarella for stretchy goodness.
- Pesto swirl: Spoon a little basil pesto on top before serving for a fresh, herby finish.
- Mega-veggie: Add shredded carrots, chopped spinach stems, or a handful of peas for more color and nutrition.
FAQ
Can I use a different pasta instead of lasagna noodles?
Yes. Short pasta like mafalda, rotini, penne, or shell pasta works great.
Adjust the cook time so the pasta stays al dente.
Do I need to brown the meat first?
Browning builds flavor and improves texture, so it’s worth the extra step. If you skip it, the soup will still cook, but the taste won’t be as rich.
Can I make this on the stovetop?
Absolutely. Simmer everything in a large pot for 30–40 minutes, then add noodles and cook until tender.
Stir in greens and cream at the end.
How do I keep the noodles from getting mushy in leftovers?
Cook the noodles separately and add them to each bowl as you reheat. Or undercook the noodles slightly when making the soup.
What cheese can I substitute for ricotta?
Cottage cheese (blended or as-is) works well. Mascarpone also gives a rich, creamy result.
Is this freezer-friendly?
Yes, but freeze without the noodles for best texture.
Add fresh cooked pasta when reheating.
Can I make it dairy-free?
Use a dairy-free ricotta and mozzarella, or skip the cheese topping and add a spoonful of cashew cream. Choose coconut milk or oat cream for a silky finish.
What if my soup tastes too acidic?
Stir in a pinch of sugar or a splash of cream to balance acidity. A small pat of butter can also round out the flavors.
