Italian White Lasagna Soup

The first time my roommate walked in while this was simmering, she actually asked if I'd spent hours making an actual lasagna from scratch. That rich, creamy aroma filling our tiny apartment completely fooled her, and honestly, it fooled me too—it tastes like the kind of Sunday dinner that usually requires an entire afternoon of layering noodles and sauce. Instead, I'd thrown everything into one pot in under twenty minutes, letting the pasta break down just enough to thicken the broth into something velvety and luxurious.

Last winter, during that week when half my office was out sick with that terrible flu going around, I made a massive batch of this soup. My friend Sarah, who'd been living on tea and toast for days, sent me a text at midnight saying she'd just finished her third bowl and finally felt human again. There's something about the combination of warm broth, tender chicken, and all that melted cheese that feels like a hug, especially when you need it most.

Ingredients

• 400 g (14 oz) boneless, skinless chicken breast or thighs, diced: Cutting the chicken into bite-sized pieces before cooking helps it cook evenly and stay tender. Thighs add extra richness if you prefer a more luxurious soup.
• 1 tablespoon olive oil: This creates the foundation for sautéing your aromatics. Extra virgin gives you a nice fruity base note.
• 1 medium onion, finely chopped: The onion provides sweetness that balances the creamy elements. Finely chopped pieces dissolve into the broth as they cook.
• 3 cloves garlic, minced: Fresh garlic is essential here—it blooms quickly in the hot oil and infuses the entire soup with aromatic depth.
• 2 medium carrots, diced: These add natural sweetness and beautiful color. Cut them small so they soften in the same time it takes the pasta to cook.
• 2 celery stalks, diced: The celery provides that classic savory backbone. Keep the pieces relatively uniform with your carrots for even cooking.
• 150 g (5 oz) baby spinach: Spinach wilts beautifully into hot broth and adds fresh color and nutrition without overpowering the creamy flavors.
• 1.2 liters (5 cups) low-sodium chicken broth: Low-sodium broth lets you control the seasoning. Homemade broth is wonderful, but a good quality store-bought version works perfectly.
• 1 teaspoon dried Italian herbs: This blend typically includes oregano, basil, thyme, and rosemary. It echoes the flavors of traditional lasagna seasoning.
• 1/2 teaspoon crushed red pepper flakes (optional): Just a hint of heat cuts through all that creaminess and adds complexity. Adjust based on your spice tolerance.
• Salt and black pepper to taste: Taste and adjust at the end—different broths vary wildly in salt content, and you want the final seasoning just right.
• 200 g (7 oz) lasagna noodles, broken into 2-inch pieces: Breaking the noodles exposes more surface area to the broth, helping them release starch and naturally thicken the soup.
• 120 ml (1/2 cup) heavy cream: This adds that luxurious mouthfeel that makes the soup feel like lasagna. Warm it slightly before adding to prevent curdling.
• 250 g (1 cup) ricotta cheese: Ricotta melts into the hot broth, creating those lovely creamy pockets reminiscent of actual lasagna layers.
• 100 g (1 cup) shredded mozzarella: Mozzarella adds the signature stretch and mild flavor. It melts beautifully and creates those satisfying cheese pulls.
• 40 g (1/4 cup) grated Parmesan: Aged Parmesan brings salty umami that deepens all the other flavors. Freshly grated melts much better than pre-shredded.
• 2 tablespoons chopped fresh parsley, plus extra for garnish: Fresh parsley adds bright, herbal notes that cut through the richness. A final sprinkle makes each bowl look inviting.

Instructions

Build Your Flavor Base:

Heat olive oil in a large pot over medium heat until it shimmers. Add onion, carrots, and celery, sautéing for 5 minutes until softened and fragrant, stirring occasionally to prevent browning.

Add Aromatics and Chicken:

Stir in garlic and sauté for just 1 minute until fragrant. Add diced chicken and cook until lightly golden, about 4 to 5 minutes—the chicken will finish cooking in the broth, so do not overcook it now.

Create the Broth:

Pour in chicken broth, dried Italian herbs, red pepper flakes, salt, and black pepper. Bring to a gentle boil, letting the herbs rehydrate and infuse the liquid with their aromatic oils.

Cook the Pasta:

Add broken lasagna noodles, reduce heat to maintain a steady simmer, and cook for 15 minutes. Stir occasionally to prevent sticking, and cook until noodles are al dente and the broth begins to thicken slightly.

Wilt the Spinach:

Add spinach and cook until just wilted, about 1 to 2 minutes. The spinach will shrink dramatically, so add it in batches if your pot seems crowded.

Make It Creamy:

Lower the heat and stir in heavy cream, ricotta, mozzarella, and Parmesan. Stir gently until all cheeses melt and the broth becomes velvety and creamy.

Finish and Season:

Add fresh parsley, taste, and adjust salt and pepper as needed. Remove from heat and let the soup rest for 5 minutes to allow flavors to meld.

Serve with Love:

Ladle hot soup into bowls and garnish each serving with additional parsley and Parmesan. The soup continues to thicken as it sits, so serve immediately for the best texture.

Save

My grandmother used to say that soup was better the second day because all the ingredients had time to make friends. When I make this for Sunday dinner, I always deliberately make extra, and Monday's lunch is honestly what I look forward to all morning. The pasta absorbs more broth, the cheese flavors deepen, and something about the overnight rest transforms it from delicious into absolutely divine.

Making It Vegetarian

Swapping chicken for cannellini beans creates an equally hearty and satisfying version of this soup. The beans add creaminess and protein while letting the vegetables and cheese take center stage. Use a good quality vegetable broth and you will not miss the meat at all—actually, several vegetarian friends have told me they prefer this version to the original.

Getting the Perfect Texture

The magic happens when those broken lasagna noodles release their starch into the broth, naturally thickening it without any flour or roux. If you prefer a thicker soup, let it simmer uncovered for a few extra minutes until it reaches your desired consistency. Conversely, if it becomes too thick, a splash more broth brings it right back to perfect.

Serving Suggestions

A hunk of crusty Italian bread is absolutely non-negotiable for sopping up every last drop of that cheesy broth. I also love a simple green salad with bright vinaigrette to cut through all the richness. A crisp Pinot Grigio or Sauvignon Blanc pairs beautifully, cleansing your palate between spoonfuls of that decadent creaminess.

• Warm your bowls in the oven for a few minutes before serving—the soup stays hot longer and feels extra special
• Set out extra red pepper flakes and grated Parmesan at the table so everyone can customize their bowl
• A drizzle of good olive oil over each serving adds a lovely silky finish and fruity brightness

Save

There is something deeply satisfying about a recipe that takes the familiar, beloved flavors of a classic dish and transforms them into something completely new but equally comforting. This soup has become my go-to for cold nights, sick friends, and those evenings when only something cheesy and warm will do.

Recipe FAQs

→ Can I make this soup vegetarian?

Yes, substitute diced chicken with cannellini beans and swap chicken broth for vegetable broth. The beans provide protein while maintaining the soup's hearty texture.

→ What type of noodles work best?

Traditional lasagna noodles broken into 2-inch pieces work perfectly. You can also use no-boil lasagna sheets or substitute with mafalda or fettuccine broken into smaller pieces.

→ How do I store and reheat leftovers?

Store in an airtight container for up to 4 days. The noodles will continue absorbing broth, so you may need to add extra liquid when reheating. Reheat gently over medium-low heat, stirring occasionally.

→ Can I freeze this soup?

Freezing works best without the noodles. Prepare the soup through step 5, cool completely, and freeze for up to 3 months. When ready to serve, thaw and add fresh noodles during the final 15 minutes of cooking.

→ What can I serve alongside?

Crusty Italian bread or garlic bread is perfect for soaking up the creamy broth. A simple green salad with vinaigrette balances the richness, and the dish pairs beautifully with Pinot Grigio or Sauvignon Blanc.

→ How can I adjust the spice level?

The red pepper flakes are optional. Omit them for a mild version, increase to 1 teaspoon for moderate heat, or add a pinch of cayenne pepper if you prefer a spicier kick.
