Quick White Lasagna Soup

Last winter, during that brutally cold week when nobody wanted to leave the house, my teenage son wandered into the kitchen complaining that regular chicken soup felt like punishment food. I stared at a box of lasagna noodles sitting on the counter and had one of those ridiculous lightbulb moments—what if I smashed everything together in a pot?

That first attempt was chaos—noodles everywhere, ricotta floating in suspicious clumps—but the flavor was somehow exactly right. My daughter took three bowls and announced this was now her official sick day food, which is basically the highest rating possible in our house.

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 those aromatics until they're fragrant and golden
• 1 medium onion, diced: Sweet onions work particularly well, adding subtle sweetness to balance the rich cream
• 2 garlic cloves, minced: Fresh garlic makes all the difference—jarred stuff just does not compare here
• 2 cups baby spinach: The spinach wilts down beautifully and adds color without overpowering the dish
• 6 cups low-sodium chicken broth: Control your salt level by starting with low-sodium broth
• 1 cup whole milk: Whole milk creates that velvety texture without making the soup too heavy
• 1 cup heavy cream: This is what transforms a good soup into something that feels indulgent and special
• 8 lasagna noodles, broken into 2-inch pieces: Breaking them yourself creates perfectly rustic, imperfect pieces that catch all the cheesy goodness
• 1 cup ricotta cheese: Use whole milk ricotta for the creamiest results, part-skim can feel grainy
• 1 ½ cups shredded mozzarella cheese: Freshly shredded melts infinitely better than pre-shredded bags with anti-caking agents
• ½ cup grated Parmesan cheese: Adds that salty, nutty depth that makes the soup taste properly Italian-American
• 1 teaspoon dried Italian herbs: Or use a mix of dried oregano and basil if that is what you have in your pantry
• ½ teaspoon ground black pepper: Freshly cracked pepper adds warmth and complements the cream beautifully
• ½ teaspoon salt: Start here and adjust at the end—different broths have different salt levels
• Pinch of crushed red pepper flakes: Optional, but adds just enough warmth to make each spoonful interesting

Instructions

Sauté the aromatics:

Heat that olive oil in your large soup pot over medium heat until it shimmers slightly. Toss in the diced onion and cook for 3 to 4 minutes until it turns translucent and smells sweet. Add the minced garlic and let it cook for just 1 minute—you want it fragrant, not browned or bitter.

Cook the noodles:

Pour in the chicken broth and bring everything to a gentle bubble, not a rolling boil. Drop in those broken lasagna noodle pieces and cook uncovered for 8 to 10 minutes. You want them al dente because they will continue softening in the creamy broth later.

Add the creamy base:

Stir in the shredded chicken along with those Italian herbs, salt, pepper, and red pepper flakes if you like some heat. Pour in the milk and heavy cream, then let everything simmer together for 5 minutes. The soup should start looking thicker and more cohesive now.

Melt in the cheese:

Toss in the spinach and watch it wilt down beautifully, just 1 to 2 minutes. Stir in the ricotta, mozzarella, and Parmesan until melted and the soup turns gloriously creamy. Taste and adjust the seasoning if needed—this is your last chance before serving.

Save

Last month, my neighbor came over sniffing the air through an open window. She ended up staying for dinner with her family, and now our whole block makes this on Tuesday nights. Something about soup that tastes like lasagna just brings people together.

Make It Your Own

Sometimes I swap in turkey leftovers from Thanksgiving, or go completely vegetarian with sautéed mushrooms and extra spinach. The base recipe is forgiving enough that you can adapt it to whatever is in your fridge without ruining the magic.

Serving Suggestions

Crusty bread is non-negotiable in our house—we need something substantial for dragging through that cheesy broth. Garlic toast feels like overkill, but honestly, who am I to judge if you want to double down on garlic and butter?

Make Ahead Strategy

The soup actually tastes better the next day, which is saying something for something already this good. The flavors meld together beautifully overnight, though the pasta will absorb more liquid so you might need to splash in extra broth when reheating. I often make a double batch on Sunday and portion it out for easy weeknight dinners.

• Cool completely before storing in the refrigerator
• Store noodles separately if you want to prevent them from becoming too soft
• Reheat gently over low heat, stirring occasionally to prevent separating

Save

There is something profoundly comforting about a soup that tastes like a hug from your Italian grandmother, even if you do not have one. Hope this brings your family as much warmth as it has brought mine.

Recipe FAQs

→ Can I make this vegetarian?

Yes, simply omit the shredded chicken and add sautéed mushrooms or extra spinach instead. The soup remains hearty and satisfying without the meat.

→ What type of pasta works best?

Traditional lasagna noodles broken into pieces work perfectly, but you can also use other flat pasta like fettuccine or linguine broken into smaller pieces.

→ Can I freeze this soup?

The soup freezes well for up to 3 months, though the pasta may soften slightly upon reheating. Consider freezing without the pasta and adding fresh noodles when reheating.

→ How do I prevent the cream from curdling?

Add the milk and heavy cream at the end of cooking and keep the heat at a gentle simmer rather than a rolling boil. This helps maintain the smooth, creamy texture.

→ What can I serve with this soup?

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