Step-by-Step Instructions

1. Brown the Sausage and Aromatics:

Warm a large pot over medium heat, then swirl in 1 tablespoon of olive oil, ensuring the base is evenly coated. Add 1 pound Italian sausage, breaking it into crumbles, and cook until browned. Toss in 1 small onion, finely diced, and sauté until it turns soft and slightly see-through. Stir in 3 minced garlic cloves and cook for another minute until fragrant.​

2. Add Mushrooms (Optional) and Broth:

If using, add 8 ounces sliced mushrooms to the pot and cook until tender. Pour in 4 cups chicken broth, scraping up any browned bits from the bottom. Stir in 1 teaspoon dried oregano and ½ teaspoon dried basil. Bring to a gentle simmer.​

3. Cook the Lasagna Noodles:

Add 6 broken lasagna noodles to the simmering broth. Cook for 10–12 minutes, stirring occasionally, until tender.​

4. Prepare the Alfredo Sauce:

In a separate saucepan, melt 3 tablespoons unsalted butter over medium heat. Whisk in 3 tablespoons all-purpose flour and cook for about a minute. Gradually whisk in 1 cup whole milk and 1 cup heavy cream until smooth. Continue cooking, stirring constantly, until the sauce thickens (3–5 minutes). Take the pan off the heat and stir in 1 cup of grated Parmesan, mixing until it melts into a smooth, creamy finish. Season with ¼ teaspoon white pepper, if desired.​ For more homemade sauce inspiration, including a deeper dive into Alfredo, don’t miss this delicious guide to easy pasta sauces!

Tips, Variations & Substitutions

Make It High Protein or Turkey-Based

• Use lean ground turkey or chicken to boost the protein content while keeping the soup light. This adjustment transforms it into a high protein lasagna soup that’s both hearty and nutritious.​
  

Gluten-Free or Low Carb Options

• Substitute traditional lasagna noodles with gluten-free pasta to create a gluten-free lasagna soup. Ensure all other ingredients, like broth and seasonings, are certified gluten-free.​
  
• For a low-carb or keto-friendly version, replace lasagna noodles with zucchini ribbons or shirataki noodles. This modification results in a keto lasagna soup that’s both satisfying and aligns with low-carb dietary preferences.​
  

Add a Spicy Kick

What to Serve with Alfredo Lasagna Soup

• Garlic Bread

• Simple Green Salad
  A light salad with fresh greens and a tangy vinaigrette provides a refreshing contrast to the rich soup, balancing the meal. ​
  
• Roasted Vegetables
  Oven-roasted vegetables like asparagus or zucchini add a hearty and nutritious element to your meal, enhancing both flavor and texture. ​
  
• Low-Carb Crackers (for keto versions)
  For a low-carb option, pair the soup with keto-friendly crackers to maintain the desired texture without adding extra carbohydrates.​

Mistakes to Avoid

When preparing creamy Alfredo lasagna soup, sidestepping common pitfalls can ensure a delicious outcome. Here are common mistakes to avoid:

• Overcooking the noodles
  Adding lasagna noodles too early or cooking them for too long can result in a mushy texture. It’s advisable to add the noodles once the broth is boiling and monitor them closely, cooking just until al dente. ​
  
• Adding cream too early
  Introducing dairy products like cream at high temperatures or too early in the cooking process can cause curdling. To prevent this, lower the heat before adding cream and ensure it’s warmed to room temperature. ​
  
• Underseasoning the base
  Neglecting to season the soup adequately can lead to a bland flavor. Season with salt and pepper during each stage of cooking, tasting as you go to build a well-rounded flavor profile. ​
  
• Using low-quality cheese
  Opting for pre-shredded or low-quality cheese can affect the soup’s texture and taste. Freshly grated Parmesan melts more smoothly and enhances the overall flavor of the dish. ​
  

By being mindful of these factors, you can ensure your creamy Alfredo lasagna soup turns out rich, flavorful, and satisfying.
