Quick White Lasagna Soup

The steam rising from my bowl carried that impossible combination of garlic and cream that makes you stop whatever you are doing. My sister had called complaining about the weather, something about gray skies and needing comfort, and I had remembered a rotisserie chicken sitting in the fridge from dinner two nights before. Sometimes the best meals start with leftovers and a craving for something that feels like a hug.

Last February during a snow storm, my neighbor texted that she was running on empty and needed something warm. I brought over a container of this soup, and she messaged me an hour later saying her kids had asked when I could move in. The way the spinach wilts into those tender green ribbons makes it feel fancy without any actual effort.

Ingredients

• 2 cups cooked chicken, shredded: Rotisserie chicken works perfectly here, or use leftover roast chicken from Sunday dinner
• 1 tablespoon olive oil: The foundation for sautéing your aromatics
• 1 medium onion, diced: Sweet onions work beautifully, but yellow onions are perfectly fine
• 2 garlic cloves, minced: Fresh garlic makes all the difference in the base flavor
• 2 cups baby spinach: It wilts down significantly, so do not be shy with it
• 6 cups low-sodium chicken broth: Starting with low-sodium lets you control the salt level precisely
• 1 cup whole milk: Adds body without making the soup too heavy
• 1 cup heavy cream: This creates that luxurious lasagna texture
• 8 lasagna noodles, broken into 2-inch pieces: Breaking them yourself creates perfectly rustic, bite-sized noodles
• 1 cup ricotta cheese: The secret ingredient that mimics authentic lasagna layers
• 1 ½ cups shredded mozzarella cheese: For that perfect melt and stretch
• ½ cup grated Parmesan cheese: Adds the necessary salty, savory depth
• 1 teaspoon dried Italian herbs: Oregano, basil, and thyme blend works well here
• ½ teaspoon ground black pepper: Freshly cracked gives the best aroma
• ½ teaspoon salt: Adjust at the end since broth and cheese both add saltiness
• Pinch of crushed red pepper flakes: Optional, but lovely for gentle background warmth

Instructions

Build your flavor base:

Heat olive oil in a large pot over medium heat, add diced onion, and cook 3 to 4 minutes until translucent and fragrant, then stir in garlic for just 1 minute until it becomes aromatic

Cook the noodles:

Pour in the chicken broth and bring to a gentle boil, add broken lasagna noodles, and cook uncovered for 8 to 10 minutes until they are al dente

Create the creamy base:

Stir in the shredded chicken, Italian herbs, salt, pepper, and red pepper flakes if using, then add the milk and heavy cream and let everything simmer together for 5 minutes

Add the finishing touches:

Drop in the spinach and cook just until wilted, about 1 to 2 minutes, then stir in ricotta, mozzarella, and Parmesan until melted and the soup reaches perfect creaminess

Season and serve:

Taste and adjust salt and pepper as needed, then serve hot with extra Parmesan and fresh cracked pepper if desired

Save

My friend Sarah once made this for her book club and served it with individual ramekins of extra garlic bread on the side. She said the silence when everyone started eating was the best compliment she could have asked for.

Making It Your Own

I have swapped in turkey, leftover Thanksgiving meat, and even sautéed mushrooms when my vegetarian brother came over. The beauty of this soup is how flexible it is while still tasting like something you spent all day making.

The Wine Secret

Splash some dry white wine in with the onions after they have softened, let it reduce for about 2 minutes before adding the broth. It adds a subtle brightness that cuts through all that rich creaminess.

Perfect Pairings

Crusty bread is practically mandatory here, but garlic toast takes it over the top. A simple green salad with lemon vinaigrette helps balance the richness.

• Grill some parmesan-crusted bread alongside
• Keep red pepper flakes on the table for heat lovers
• Extra Parmesan is never a bad idea

Save

There is something deeply satisfying about transforming all the comfort of lasagna into a soup that comes together faster than you can preheat your oven. Make it on a Tuesday and pretend you cooked all day.

Recipe FAQs

→ Can I make this vegetarian?

Yes, simply omit the shredded chicken and add sautéed mushrooms or extra spinach for a vegetarian version. The creamy broth and cheesy elements remain just as satisfying.

→ What type of noodles work best?

Traditional lasagna noodles broken into 2-inch pieces are ideal because they hold their shape well. No-boil noodles can also work but may absorb more liquid during cooking.

→ Can I use milk instead of heavy cream?

For a lighter version, substitute half-and-half or use more whole milk instead of heavy cream. The soup will still be creamy but with less richness and fewer calories.

→ How should I store leftovers?

Store in an airtight container in the refrigerator for up to 3 days. The noodles will continue absorbing liquid, so add a splash of broth or milk when reheating to restore consistency.

→ Can I freeze this soup?

Freezing is possible but may affect texture—the noodles can become mushy and dairy may separate. For best results, freeze without noodles and add fresh pasta when reheating.

→ What sides pair well with this?

Crusty bread, garlic toast, or a simple green salad complement the rich, creamy broth perfectly. The bread helps soak up every bit of the cheesy, flavorful liquid.
