Italian White Lasagna Soup

WANT TO SAVE THIS RECIPE?

I have a soft spot for comfort food, and nothing quite hits the spot like a warm, creamy bowl of this Italian White Lasagna Soup. It’s everything I love about a classic white lasagna—rich béchamel, tender chicken, wilted spinach, and perfectly cooked noodles—but in spoonable, soul-soothing form. Whether it’s a chilly evening or a busy weekday when you need something cozy and filling, this soup delivers every single time.

What makes this soup truly special is the depth of flavor packed into every bite. Between the garlic-kissed broth, a splash of cream, and the addition of sun-dried tomatoes and herbs, each spoonful tastes like a carefully layered bite of lasagna. I’ve made this soup for friends, family, and quiet nights alone, and it never disappoints.

Why You’ll Love This Italian White Lasagna Soup

This soup brings all the lasagna goodness without the fuss of baking. It’s hearty, creamy, and layered with familiar Italian flavors that feel both nostalgic and elevated. The combination of rotisserie chicken, fresh spinach, and tender noodles swimming in a garlic-Parmesan broth makes it ideal for both weeknight dinners and weekend gatherings. Plus, it comes together in just one pot, which means fewer dishes and more flavor.

What Kind of Pasta Should I Use?

While traditional lasagna noodles are great, I often use egg noodles or mafaldine pasta (those frilly-edged ribbons) to keep things simple and slurpable. Egg noodles cook quickly and hold up well in the creamy broth, but if you’re a fan of the full lasagna experience, you can break up classic lasagna sheets into smaller pieces before adding them to the pot.

Options for Substitutions

This recipe is surprisingly flexible:

• Protein: You can swap chicken for turkey, ground Italian sausage, or even plant-based meat alternatives.
• Dairy-Free: Use unsweetened oat milk and dairy-free cheese alternatives to make it vegan-friendly.
• Gluten-Free: Choose your favorite gluten-free pasta and thicken the soup with a cornstarch slurry instead of flour.
• Spinach: Kale or Swiss chard work beautifully if you want a heartier green.

Whether you’re customizing based on diet or pantry availability, this soup can adapt without losing its comforting Italian soul.

Step 1: Sauté the Aromatics

Heat olive oil in a large pot over medium heat. Add diced onion and cook for about 3–4 minutes until translucent. Add minced garlic and cook for another minute until fragrant, stirring constantly to prevent burning.

---

Step 2: Build the Base

Sprinkle the flour over the onions and garlic. Stir continuously for about 1–2 minutes to form a light roux. Slowly pour in the chicken broth while stirring to prevent lumps. Bring the mixture to a gentle simmer.

---

Step 3: Add Chicken and Seasonings

Stir in shredded rotisserie chicken, Italian seasoning, salt, pepper, and sun-dried tomatoes. Let it simmer for 10 minutes so the flavors can meld together.

---

Step 4: Stir in Cream and Noodles

Pour in the heavy cream and bring the soup back to a simmer. Add the egg noodles and cook until tender, about 7–9 minutes, depending on the type of noodles used.

---

Step 5: Add Spinach and Cheese

Once the noodles are cooked, stir in the fresh spinach and Parmesan cheese. Stir gently until the spinach wilts and cheese melts into the broth. Taste and adjust seasoning if needed.

---

Step 6: Serve Hot

Ladle the soup into bowls and top with extra Parmesan, a sprinkle of red pepper flakes, or freshly cracked black pepper. Serve with crusty bread or garlic toast.

How Long to Prepare the Italian White Lasagna Soup

Prep Time: If you’re using rotisserie chicken, prep is quick—just 10–15 minutes to chop the onion, garlic, and sun-dried tomatoes, and shred the chicken. Prepping your workspace and measuring ingredients ahead makes the process smooth and fast.

Cook Time: The soup simmers in layers. From sautéing the aromatics to cooking the noodles and wilting the spinach, expect about 30 minutes of active cooking. In total, the soup is ready to enjoy in about 45 minutes from start to finish.

Tips for Perfect Italian White Lasagna Soup

• Use low-sodium chicken broth so you can better control the salt level.
• Shred the chicken finely so it distributes evenly in every spoonful.
• Add the noodles last to avoid them getting overly soft.
• Use fresh grated Parmesan rather than pre-packaged for the best flavor and melting quality.
• Let it sit for 5 minutes before serving to allow the flavors to settle and the soup to thicken slightly.

---

Watch Out for These Mistakes While Cooking

• Overcooking the noodles: They can quickly become mushy if left simmering too long.
• Skipping the roux step: This is key for achieving that creamy texture without the need for loads of cream.
• Using pre-shredded cheese: It often has anti-caking agents that affect melting.
• Adding spinach too early: It will wilt too much and lose its color and texture.
• Not seasoning in layers: Taste as you go to make sure every element is well balanced.

What to Serve With Italian White Lasagna Soup?

1. Garlic Bread

Crispy on the outside, buttery on the inside—perfect for soaking up that creamy broth.

2. Caesar Salad

The crisp, salty crunch complements the richness of the soup.

3. Roasted Vegetables

Lightly roasted carrots, zucchini, or bell peppers balance out the creaminess.

4. Bruschetta

A fresh tomato topping adds brightness and texture.

5. White Wine

A glass of Pinot Grigio or Sauvignon Blanc pairs beautifully with the creamy, herby flavors.

Storage Instructions

Refrigerator: Let the soup cool completely before transferring to an airtight container. It will keep well in the fridge for up to 4 days. When reheating, add a splash of broth or cream to loosen the consistency, as the noodles tend to absorb liquid over time.

Freezer: For best results, freeze the soup without the noodles (they can become mushy when thawed). Store in a freezer-safe container for up to 2 months. Reheat on the stovetop and add freshly cooked noodles before serving.

Frequently Asked Questions

What if I don’t have rotisserie chicken?

You can use leftover cooked chicken breast or thigh meat, or poach raw chicken in the broth before shredding.

Can I make this soup ahead of time?

Yes, but store the noodles separately if you plan to enjoy it over several days to keep them from getting soggy.

Is this soup gluten-free?

Not as written, but it can be made gluten-free by using GF pasta and a cornstarch slurry instead of flour.

Can I use milk instead of cream?

You can, but it won’t be as rich. Whole milk is preferred if you’re skipping the cream.
