Ingredients List

For the Soup Base:

• 2 tablespoons extra virgin olive oil (or unsalted butter for extra richness)
• 1 pound Italian sausage (sweet or spicy, based on preference; turkey sausage works as a leaner substitute)
• 1 medium yellow onion, diced (approximately 1½ cups)
• 4 cloves fresh garlic, minced (or 1½ teaspoons garlic powder)
• 4 cups low-sodium chicken broth (vegetable broth for vegetarian adaptation)
• 2 cups whole milk (2% milk acceptable, though less creamy)
• 1½ cups heavy cream (half-and-half reduces richness but still works)
• 8 lasagna noodles, broken into bite-sized pieces (oven-ready or traditional; gluten-free options available)
• 2 teaspoons Italian seasoning (or combine equal parts dried basil, oregano, and thyme)
• 1 teaspoon dried basil
• ½ teaspoon red pepper flakes (optional, for subtle heat)
• Salt and freshly ground black pepper to taste

For the Cheese Blend:

• 1½ cups freshly shredded mozzarella cheese (pre-shredded contains anti-caking agents that affect texture)
• 1 cup freshly grated Parmesan cheese (Parmigiano-Reggiano preferred for authentic flavor)
• ½ cup whole milk ricotta cheese (part-skim acceptable)
• 2 tablespoons cream cheese (adds extra silkiness to the broth)

For Garnish:

• Fresh basil leaves, torn or chiffonade
• Additional Parmesan cheese
• Fresh parsley, chopped
• Garlic bread or crusty Italian bread for serving

Substitution Tips: For a lighter version, swap Italian sausage with ground chicken or turkey. Dairy-free enthusiasts can use coconut milk and cashew cream, though the flavor profile shifts significantly. Gluten-sensitive cooks should opt for gluten-free lasagna noodles, which perform remarkably well in soup applications.

Timing

Total Time: 45 minutes (approximately 32% faster than traditional baked lasagna, which averages 90-120 minutes)

• Prep Time: 15 minutes (includes chopping vegetables, measuring ingredients, and breaking noodles)
• Cook Time: 30 minutes (active cooking with minimal hands-on attention required)
• Resting Time: None required (serve immediately for best texture)

This quick lasagna soup fits perfectly into weeknight dinner rotations. Compared to conventional lasagna that demands 45 minutes of prep, 45 minutes of baking, and 15 minutes of resting, this streamlined approach delivers comparable satisfaction in a fraction of the time. The beauty lies in the one-pot methodology—everything cooks together, allowing flavors to meld while you tackle other tasks or simply relax.

Step-by-Step Instructions

Step 1: Brown the Italian Sausage

Heat olive oil in a large Dutch oven or heavy-bottomed soup pot over medium-high heat. Once shimmering (approximately 2 minutes), add the Italian sausage, breaking it apart with a wooden spoon or spatula into bite-sized crumbles. Cook for 6-8 minutes until the sausage develops a golden-brown exterior and reaches an internal temperature of 160°F.

Pro Tip: Resist the urge to stir constantly. Allowing the sausage to sit undisturbed for 2-3 minutes creates flavorful caramelization through the Maillard reaction, adding depth to your soup base. If using leaner meats like turkey sausage, you may need to add an extra tablespoon of oil to prevent sticking.

Step 2: Sauté Aromatics

Reduce heat to medium and add diced onion to the pot with the browned sausage. Sauté for 4-5 minutes until the onion becomes translucent and softened, stirring occasionally. Add minced garlic and cook for an additional 60 seconds until fragrant but not browned (burnt garlic introduces bitterness).

Kitchen Insight: This foundational step, known as building a flavor base, is crucial in Italian cooking. The onion sweetens as it cooks, while garlic provides aromatic complexity. The rendered fat from the sausage carries these flavors throughout the entire dish.

Step 3: Add Liquids and Seasonings

Pour in chicken broth, whole milk, and heavy cream, stirring to combine and scraping up any browned bits (fond) from the bottom of the pot—this adds tremendous flavor. Add Italian seasoning, dried basil, red pepper flakes (if using), and season generously with salt (approximately 1 teaspoon) and black pepper (½ teaspoon).

Temperature Control: Increase heat to medium-high and bring the mixture to a gentle boil. This should take approximately 5-7 minutes. Watch carefully to prevent boiling over, especially once dairy is added—cream-based soups are notorious for overflowing quickly.

Step 4: Cook the Lasagna Noodles

Once the soup reaches a boil, add the broken lasagna noodles, ensuring they’re submerged in the liquid. Reduce heat to maintain a steady simmer (small bubbles breaking the surface, not a rolling boil). Cook for 10-12 minutes, stirring every 2-3 minutes to prevent noodles from clumping or sticking to the bottom.

Texture Tip: Oven-ready (no-boil) lasagna noodles absorb more liquid and create a thicker, more stew-like consistency. Traditional lasagna noodles maintain their shape better and provide a clearer broth. Test noodles at the 10-minute mark—they should be al dente, with just a slight firmness when bitten. They’ll continue softening slightly as they sit in the hot soup.

Step 5: Create the Creamy Cheese Blend

While noodles simmer, prepare your cheese mixture in a medium bowl. Combine ricotta cheese, cream cheese, and half of the mozzarella (¾ cup). Mix until relatively smooth—this creates pockets of creamy richness throughout the soup rather than having cheese sink to the bottom.

Scientific Advantage: Pre-mixing cheeses prevents the stringy, clumpy texture that occurs when cheese is added directly to hot liquid. The ricotta and cream cheese act as emulsifiers, helping mozzarella incorporate smoothly into the broth.

Step 6: Incorporate Cheese and Finish

Once noodles are tender, reduce heat to low. Add the cheese mixture by the spoonful, stirring gently after each addition until melted and incorporated. Add Parmesan cheese and remaining mozzarella (¾ cup), stirring until completely melted and the soup achieves a luxuriously creamy consistency.

Quality Check: The soup should coat the back of a spoon and have a silky, cohesive appearance. If it seems too thick, add chicken broth ¼ cup at a time. If too thin, simmer uncovered for 3-5 additional minutes to reduce liquid and concentrate flavors.

Step 7: Season and Serve

Taste and adjust seasoning with additional salt, pepper, or Italian herbs as needed. Remove from heat and let stand for 2-3 minutes to allow flavors to settle. Ladle into bowls and garnish generously with fresh basil, additional Parmesan cheese, and a drizzle of quality olive oil if desired.

Serving Suggestion: Pair with garlic bread, crusty Italian bread, or a simple arugula salad dressed with lemon vinaigrette. The soup’s richness balances beautifully with bitter greens and acidic elements. For an elevated presentation, serve in pre-warmed bowls to maintain optimal serving temperature.

Nutritional Insights: This creamy alfredo lasagna soup provides substantial protein from Italian sausage and three cheese varieties, making it a satisfying complete meal. The calcium content is particularly impressive at 42% of daily value, supporting bone health. While the saturated fat content is significant, this is typical of authentic Italian cream-based dishes. For a lighter version, substitute half the heavy cream with additional milk and use turkey sausage, reducing calories by approximately 140 per serving and saturated fat by 8g.

Dietary Considerations: This recipe is naturally gluten-free when using certified gluten-free lasagna noodles. It’s not suitable for dairy-free or vegan diets without substantial modifications. The high sodium content primarily comes from sausage and cheese; using low-sodium broth and reducing added salt can lower sodium levels by 20-25%.

Storage and Reheating Tips

Refrigeration: Store leftover lasagna alfredo soup in an airtight container for up to 4 days. Note that noodles will continue absorbing liquid as the soup sits, resulting in a thicker consistency. Add ¼-½ cup broth or milk when reheating to restore the original texture.

Reheating: Warm gently over medium-low heat on the stovetop, stirring frequently to prevent scorching. Microwave reheating works in 60-90 second intervals, stirring between each cycle. Avoid high heat, which can cause dairy to separate.

Freezing: While possible, freezing is not recommended for cream-based soups. Dairy tends to separate and become grainy upon thawing. If you must freeze, do so for no longer than 1 month and whisk vigorously while reheating to re-emulsify.
