Quick White Lasagna Soup

The first time I made this soup was during a particularly brutal February when my apartment felt like an icebox and I was craving something that felt like a hug but didnt require three hours of oven time. I had half a rotisserie chicken, a box of lasagna noodles nobody had touched in months, and the sudden realization that soup might just be the answer to everything.

My roommate walked in mid-simmer and literally stopped in her tracks asking what smelled like an Italian grandmother had moved in. That night we ate straight from the pot standing up in the kitchen because waiting for bowls to be set felt like asking too much.

Ingredients

• 2 cups cooked chicken shredded: Rotisserie chicken works beautifully here or use leftover roasted chicken from Sunday dinner
• 1 tablespoon olive oil: Creates the foundation for sautéing your aromatics
• 1 medium onion diced: Sweet onions work beautifully but yellow onions are perfectly fine too
• 2 garlic cloves minced: Fresh garlic makes all the difference so avoid the pre-minced stuff
• 2 cups baby spinach: The spinach wilts down beautifully and adds such a lovely fresh element
• 6 cups low-sodium chicken broth: Low-sodium is crucial here since well be adding cheese later
• 1 cup whole milk: Whole milk gives that luxurious mouthfeel
• 1 cup heavy cream: This is what makes it truly lasagna-like in richness
• 8 lasagna noodles broken into pieces: Breaking them creates more surface area for that perfect texture
• 1 cup ricotta cheese: Room temperature ricotta melts into the soup more evenly
• 1 ½ cups shredded mozzarella cheese: Freshly shredded melts better than the pre-shredded bags
• ½ cup grated Parmesan cheese: Adds that salty umami punch at the end
• 1 teaspoon dried Italian herbs: A blend of oregano basil and thyme works wonderfully
• ½ teaspoon ground black pepper: Freshly cracked gives the best aroma
• ½ teaspoon salt: Start with this and adjust at the end
• Pinch of crushed red pepper flakes: Optional but that tiny kick is so worth it

Instructions

Sauté your aromatics:

Heat olive oil in your large pot over medium heat and cook the diced onion for about 4 minutes until it turns translucent and fragrant. Add the minced garlic and let it cook for just one minute more until you can really smell it.

Cook the noodles directly in the broth:

Pour in the chicken broth and bring it to a gentle boil before adding your broken lasagna pieces. Cook uncovered for 10 minutes until the noodles are perfectly al dente.

Add the creamy elements:

Stir in the shredded chicken and seasonings then pour in the milk and heavy cream. Let everything simmer together for 5 minutes to marry the flavors.

Finish with spinach and cheese:

Add the spinach and watch it wilt down beautifully after just a couple minutes. Stir in all three cheeses until melted and creamy then taste and adjust seasoning if needed.

This became my go-to when my sister had her first baby and I needed something that could be made ahead and reheated perfectly. She texted me at midnight saying she had three bowls and that was the moment I knew this recipe was a keeper.

Make It Your Own

Sometimes I swap in Italian sausage instead of chicken and let me tell you it transforms the whole thing into something even more indulgent. The key is cooking the sausage first and using those rendered drippings to sauté your onions.

The Bread Situation

Crusty bread is non-negotiable here because you need something to drag through that cheesy creamy broth. I usually grab a baguette and toast slices with garlic butter while the soup simmers.

Leftovers Actually Improve

Something magical happens overnight in the refrigerator as the noodles continue soaking up that flavorful broth. The soup thickens beautifully and the flavors develop this incredible depth that makes leftover day almost better than the first.

• Store in an airtight container for up to four days
• Add a splash of broth when reheating since it thickens up
• The noodles will soften more over time which some people actually prefer

This soup has saved more weeknights than I can count and the fact that it comes together in under 40 minutes makes it absolute perfection.

Recipe FAQs

→ Can I make this soup ahead of time?

Yes, prepare the soup up to 2 days in advance and refrigerate. The noodles will absorb more liquid, so add extra broth when reheating to reach desired consistency.

→ What pasta works best if I don't have lasagna noodles?

Penne, rotini, or bow tie pasta all work beautifully. Break larger shapes into smaller pieces if preferred, and adjust cooking time based on pasta package directions.

→ How can I make this vegetarian?

Replace chicken broth with vegetable broth and omit the shredded chicken. Add sautéed mushrooms, white beans, or extra spinach for protein and substance.

→ Can I freeze this soup?

Freezing is possible but may affect texture, as dairy can separate and pasta becomes soft. For best results, freeze without noodles and cream, then add fresh when reheating.

→ What can I serve with this soup?

Crusty bread, garlic toast, or a simple green salad complement the rich, creamy base perfectly. The soup itself is substantial enough to stand alone as a main course.
