White Lasagna Soup

The first time I made this soup, it was actually a happy accident. I had intended to make traditional lasagna but realized halfway through prep that I was completely out of tomato sauce. Instead of scrapping dinner entirely, I decided to lean into what I did have on hand, and my family now requests this version more than the original.

Last winter, my neighbor was recovering from surgery and I brought over a pot of this soup. She texted me the next morning saying it was the first thing she had actually wanted to eat in days, which honestly made my whole week better too.

Ingredients

• Cooked chicken breast: Rotisserie chicken works perfectly here and saves so much time
• Ricotta cheese: Full fat ricotta creates the silkiest base for the broth
• Mozzarella cheese: Shredded fresh mozzarella melts better than the pre-shredded stuff
• Parmesan cheese: Aged Parmesan adds that deep savory umami flavor
• Chicken broth: Low sodium lets you control the seasoning better
• Whole milk: The fat content matters for the creamy consistency
• Onion: Sweet yellow onions caramelize nicely as they soften
• Garlic: Fresh garlic has much better flavor than garlic powder
• Baby spinach: Baby spinach is tender and wilts quickly without bitterness
• Butter: Unsalted butter gives you control over the final salt level
• Lasagna noodles: Breaking them into bite sized pieces makes eating so much easier
• Dried basil and oregano: These classic Italian herbs taste like comfort food
• Red pepper flakes: Just a hint adds warmth without overwhelming heat

Instructions

Build your flavor foundation:

Melt butter in your large pot over medium heat, then cook the diced onion until it is soft and translucent. Add the minced garlic and let it cook just until you can smell it throughout the kitchen, about one minute.

Create the creamy base:

Pour in both the chicken broth and whole milk, stirring gently to combine everything. Bring this mixture to a gentle simmer, watching carefully so it does not boil over.

Cook the pasta:

Add your broken lasagna pieces along with the dried basil, oregano, red pepper flakes, salt and pepper. Let everything simmer uncovered for about 10 to 12 minutes, stirring occasionally so the noodles do not stick together.

Add the heartiness:

Stir in the shredded chicken and chopped spinach, letting the soup cook for another 3 to 4 minutes. Watch as the spinach wilts down and the chicken warms through completely.

Make it irresistibly creamy:

Turn the heat down to low before adding the ricotta, mozzarella and Parmesan cheeses. Stir constantly until all the cheese has melted and the soup becomes velvety and smooth.

Serve it up:

Ladle the hot soup into bowls and add any garnishes you like. Fresh parsley and extra Parmesan on top make it feel special.

My daughter asked if we could have this for her birthday dinner instead of going out to a restaurant. That was when I realized this soup had become something more than just dinner, it had become a memory.

Make Ahead Magic

You can prepare everything except the pasta and spinach up to two days in advance. Store the broth base separately and finish cooking when you are ready to serve, which keeps the noodles from getting mushy.

Bread Pairings

A crusty baguette or homemade garlic toast is practically essential for soaking up every last drop. I like to toast slices of Italian bread rubbed with raw garlic while the soup simmers.

Freezing Instructions

Cool the soup completely before transferring to freezer safe containers, leaving about an inch of space at the top since liquids expand when frozen. It will keep well for up to three months.

• Thaw overnight in the refrigerator before reheating
• Add a splash of milk when reheating to restore creaminess
• The texture is still wonderful after freezing

There is something about this soup that makes people linger at the table longer, talking and laughing well after the bowls are empty.

Recipe FAQs

→ Can I make white lasagna soup ahead of time?

Yes, prepare the soup up to 24 hours in advance and refrigerate. The noodles will absorb more liquid, so add extra broth when reheating. Store garnishes separately and add just before serving.

→ What pasta works best for this soup?

Traditional lasagna noodles broken into pieces create the most authentic texture. Alternatively, use mafalda, reginette, or short pasta like fusilli and penne. Cook time may vary slightly with different shapes.

→ Can I freeze white lasagna soup?

The soup freezes well for up to 3 months, though the texture may become slightly thicker after thawing. Add extra milk or broth when reheating to achieve desired consistency. Avoid freezing if planning to add heavy cream.

→ How do I prevent the dairy from separating?

Keep heat at low when adding cheeses and stir constantly until melted. Avoid boiling after dairy is incorporated. If separation occurs, whisk in a small amount of warm milk or cream to re-emulsify.

→ What protein alternatives work well?

Ground turkey, Italian sausage, or shredded rotisserie chicken make excellent substitutes. For a vegetarian version, use white beans or increase the cheese quantities while using vegetable broth instead of chicken broth.

→ How can I make this gluten-free?

Use gluten-free lasagna noodles or alternative pasta like brown rice lasagna sheets. Verify that all broth and other ingredients are certified gluten-free. The cooking time for GF pasta may differ slightly.
