Quick White Lasagna Soup

The rain was coming down hard last Tuesday when my teenage son burst through the back door, proclaiming he needed something that felt like a hug in a bowl. I had half a rotisserie chicken sitting on the counter and a box of lasagna noodles I'd been meaning to use, so this soup happened entirely by accident. Within thirty minutes, we were both curled up on the couch with steaming spoons, forgetting about the storm outside. Now it is the most requested dinner whenever anyone in our house feels under the weather or just homesick for something comforting.

My neighbor smelled it cooking through our shared kitchen wall and showed up with a loaf of crusty bread before I had even finished simmering the cream. We spent the next hour dipping bread into the broth and talking about how sometimes the simplest meals become the ones we remember most. She took home the recipe and now texts me every time she makes it, which is often.

Ingredients

• 2 cups cooked chicken, shredded: Rotisserie chicken works beautifully here, but any leftover roasted chicken will do the job perfectly
• 1 tablespoon olive oil: Creates the foundation for sautéing aromatics and brings everything together
• 1 medium onion, diced: Sweet onions work best, but whatever you have in the pantry will still create that aromatic base
• 2 garlic cloves, minced: Fresh garlic is essential for building those layers of flavor that make this soup sing
• 2 cups baby spinach: Adds brightness and nutrition while wilting beautifully into the creamy broth
• 6 cups low-sodium chicken broth: Starting with low-sodium broth gives you complete control over the final seasoning
• 1 cup whole milk: The milk helps create a velvety texture without making the soup too heavy
• 1 cup heavy cream: This is what gives the soup its luxurious, restaurant-quality richness
• 8 lasagna noodles, broken into 2-inch pieces: Breaking them yourself creates perfectly rustic, uneven pieces that hold onto the sauce
• 1 cup ricotta cheese: Dolloped into the soup, it creates those creamy pockets that remind us of actual lasagna
• 1 ½ cups shredded mozzarella cheese: Freshly shredded melts better than the pre-packaged stuff
• ½ cup grated Parmesan cheese: Adds that salty, umami kick that rounds out all the flavors
• 1 teaspoon dried Italian herbs: Oregano, basil, and thyme bring that classic herb garden flavor
• ½ teaspoon ground black pepper: Freshly cracked pepper adds warmth and depth
• ½ teaspoon salt: Start with less and add more at the end since the cheeses bring their own saltiness
• Pinch of crushed red pepper flakes: Optional, but it adds a lovely background warmth

Instructions

Build the flavor foundation:

In a large pot, heat olive oil over medium heat, then add diced onion and cook for 3 to 4 minutes until translucent and fragrant. Toss in minced garlic and cook for another minute until it becomes aromatic and golden.

Cook the noodles directly in the broth:

Pour in the chicken broth and bring to a gentle boil, then add broken lasagna noodles and cook uncovered for 8 to 10 minutes. Watch them carefully because they should be al dente since they will continue cooking as the soup sits.

Add the creamy goodness:

Stir in shredded chicken, Italian herbs, salt, pepper, and red pepper flakes, then pour in the milk and heavy cream. Let everything simmer together for 5 minutes so the flavors can meld and the soup can thicken slightly.

Finish with cheese and spinach:

Add spinach and cook for just 1 to 2 minutes until wilted, then stir in ricotta, mozzarella, and Parmesan until melted and the soup becomes wonderfully creamy. Taste and adjust seasoning as needed.

Serve with love:

Ladle into bowls while piping hot, and garnish with extra Parmesan and fresh cracked pepper if you want to dress it up.

Save

My daughter requested this soup for her birthday dinner instead of going out to a restaurant, which says everything about how special it makes everyone feel. We served it in big bread bowls and everyone went back for seconds, scraping their bowls completely clean.

Making It Your Own

Substitute cooked turkey or omit the chicken for a vegetarian version, adding sautéed mushrooms instead. For extra depth, try adding a splash of dry white wine with the onions before you add the broth. The wine reduces down and adds a sophisticated layer that people will notice but cannot quite identify.

Lightening It Up

For a lighter version without sacrificing too much creaminess, swap the heavy cream for half-and-half. You can also reduce the ricotta slightly and increase the spinach for a more nutritious twist. The soup will still be satisfying but a little less indulgent.

Serving Suggestions

Crusty bread or garlic toast is absolutely essential for soaking up every last drop of the cheesy broth. A simple green salad with vinaigrette cuts through the richness beautifully.

• Grilled cheese sandwiches make this a meal kids will talk about for weeks
• A glass of crisp white wine balances the creaminess for the adults
• Leftovers reheat beautifully and actually taste better the next day

This soup has become my go-to when I need to feed people something that feels like comfort and care, all in one pot.

Recipe FAQs

→ Can I make this soup ahead of time?

Yes, you can prepare the soup base up to 2 days in advance. Store noodles separately to prevent them from becoming too soft, and add the fresh spinach and final cheese blend when reheating.

→ What can I use instead of chicken?

Cooked turkey works beautifully as a substitute. For a vegetarian version, add sautéed mushrooms or white beans for protein and texture while keeping the creamy cheesy base intact.

→ How do I store leftovers?

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

→ Can I use different pasta shapes?

Broken lasagna noodles are traditional, but you can substitute with small shells, bow ties, or cavatappi. Adjust cooking time based on pasta package instructions.

→ Is this freezer-friendly?

The soup base freezes well for up to 2 months. Freeze without pasta and add fresh noodles when reheating to maintain the best texture and consistency.

→ How can I make this lighter?

Substitute half-and-half for heavy cream and reduce the amount of cheese slightly. Adding extra vegetables like zucchini or bell peppers increases volume without adding many calories.
