White Lasagna Soup is the ultimate one-pot comfort food dinner when you want all the creamy, cheesy goodness of white chicken lasagna without spending hours layering a casserole.
I love this recipe because it takes familiar lasagna ingredients and turns them into a rich, spoonable bowl of comfort. Tender chicken, broken lasagna noodles, garlicky broth, spinach, Parmesan and creamy ricotta come together in one pot for a dinner that feels special but is genuinely easy.
Classic lasagna has deep roots in Italian cooking, but this soup takes that familiar idea in a wonderfully casual direction. Instead of building layers in a baking dish, everything cooks together so the pasta absorbs the savory broth while the cheeses create that irresistible creamy finish.
And honestly? That is exactly what makes this such a brilliant easy dinner recipe.
Why This White Lasagna Soup Works So Well
The real magic is the contrast.
You get silky, creamy broth with chewy lasagna noodles, tender shredded chicken, wilted spinach and little pockets of ricotta. Parmesan adds salty depth, while garlic and Italian seasoning give the soup that unmistakable cozy Italian-inspired flavor.
Recent versions of white lasagna soup commonly lean into chicken, spinach, lasagna noodles, Parmesan, cream and ricotta, with some variations adding mushrooms, sausage, pesto or sun-dried tomatoes.
For this version, I wanted the sweet spot: creamy but not overwhelmingly heavy, hearty but still fresh, and easy enough for a busy weeknight.
That makes it a fantastic cold-weather dinner, family meal, Sunday supper or cozy meal-prep option.
And unlike traditional lasagna, there is no waiting around for layers to bake and set.
Everything happens in one pot.
The Ingredients That Make It So Good
You don’t need a complicated shopping list here. The flavor comes from combining straightforward ingredients in the right order.
Chicken: I use boneless, skinless chicken breasts for a lean, tender result. Rotisserie chicken is an excellent shortcut when you’re trying to get dinner on the table quickly.
Lasagna noodles: Break them into rough bite-sized pieces before adding them. Those curly edges are perfect for catching the creamy broth.
Chicken broth: This forms the savory backbone of the soup. Choose a good-quality low-sodium broth so you have more control over the final seasoning.
Cream: A little heavy cream creates that luxurious white-lasagna texture without turning the entire pot into a thick sauce.
Parmesan: Freshly grated Parmesan melts beautifully and gives the broth a salty, nutty depth.
Ricotta: This is the finishing touch. Rather than stirring all of it into the pot, spooning some over each serving creates creamy little pockets throughout the bowl.
Spinach: Fresh baby spinach wilts in minutes and brings color and freshness to an otherwise rich soup.
Garlic and onion: These build the aromatic base and make the kitchen smell ridiculously good.
Italian seasoning: A simple combination of dried herbs keeps the flavor familiar and comforting.
White Lasagna Soup Recipe
Ingredients
- 1 lb boneless, skinless chicken breasts
- 1 ½ teaspoons kosher salt, divided
- ½ teaspoon freshly ground black pepper
- 3 tablespoons unsalted butter
- 1 medium yellow onion, finely diced
- 4 garlic cloves, minced
- 2 tablespoons all-purpose flour
- 6 cups low-sodium chicken broth
- 1 teaspoon Italian seasoning
- ¼ teaspoon crushed red pepper flakes, optional
- 8 oz lasagna noodles, broken into bite-sized pieces
- 1 cup heavy cream
- 2 cups fresh baby spinach
- 1 cup freshly grated Parmesan cheese
- ½ cup whole-milk ricotta
- ½ cup shredded mozzarella
- 2 tablespoons chopped fresh parsley
- Extra Parmesan and black pepper, for serving
How To Make It
1. Build the flavor base.
Melt the butter in a large Dutch oven or heavy-bottomed soup pot over medium heat.
Add the diced onion and cook for about 4–5 minutes until softened. Stir in the garlic, Italian seasoning and red pepper flakes if using.
Cook for another 30–60 seconds.
2. Create the creamy broth.
Sprinkle the flour over the onion mixture and stir continuously for about one minute.
This small step helps the finished soup develop a creamy, velvety consistency rather than simply tasting like broth with cream added at the end.
Slowly pour in the chicken broth while stirring.
3. Cook the chicken.
Add the chicken breasts and bring everything to a gentle simmer.
Cover loosely and cook for approximately 10–14 minutes, depending on the thickness of the chicken.
The chicken should reach an internal temperature of 165°F / 74°C.
Remove it from the pot and let it rest for a few minutes before shredding it with two forks.
4. Add the lasagna noodles.
Return the broth to a gentle simmer.
Break the lasagna noodles into smaller pieces and add them directly to the pot.
Cook according to the pasta package directions, usually around 8–12 minutes, stirring occasionally so the noodles don’t stick together.
You want them tender but still slightly firm.
5. Make it creamy.
Reduce the heat to low.
Return the shredded chicken to the pot and stir in the heavy cream, Parmesan and mozzarella.
Add the baby spinach and gently stir until it wilts.
Do not let the soup aggressively boil once the cream and cheese have been added. A gentle heat keeps the texture smooth.
6. Finish with ricotta.
Taste and adjust the seasoning.
Ladle the hot soup into bowls and finish each serving with a generous spoonful of ricotta, freshly cracked black pepper, Parmesan and chopped parsley.
That little ricotta finish makes a huge difference.
My Pro Tips For The Creamiest Soup
Break the noodles unevenly.
Don’t worry about making every piece identical. Different-sized pieces give the soup a more rustic, homemade appearance and create plenty of those delicious ruffled edges.
Use freshly grated Parmesan.
Pre-grated cheese can behave differently when melted into a creamy broth. Freshly grated Parmesan gives you a smoother finish and more pronounced flavor.
Don’t boil the cream.
Once the cream and cheeses go into the pot, lower the heat. You want everything to melt together gently.
Keep extra broth nearby.
Lasagna noodles continue absorbing liquid as they sit. If your leftovers become thick, add a splash of chicken broth while reheating until the soup reaches the consistency you want.
This is particularly useful for make-ahead dinners and meal prep.
Finish each bowl separately.
Don’t dump all the ricotta into the pot. A spoonful on top gives you creamy pockets that slowly melt into the hot soup.
Flavor Variations To Try
Want to make this cozy dinner your own?
Add sliced mushrooms with the onions for an earthy creamy mushroom lasagna soup.
Swap the chicken breast for shredded rotisserie chicken when you’re after a seriously fast weeknight meal.
You can also add cooked Italian sausage for a richer, more savory bowl. Sausage and spinach are particularly good together in creamy pasta-style soups.
For extra brightness, add a little lemon zest to the ricotta before serving. A similar approach is used in some modern white lasagna soup variations to balance the richness of the cheese and cream.
And if you love a little heat, increase the crushed red pepper flakes or finish your bowl with chili oil.
What To Serve With White Lasagna Soup
This soup is substantial enough to be a complete dinner, but I absolutely love serving it with something crunchy on the side.
Try warm garlic bread for dipping into that creamy Parmesan broth.
A simple arugula salad with lemon vinaigrette is another great pairing because the peppery greens and acidity cut through the richness.
For a cozy dinner party, serve smaller bowls alongside roasted vegetables and crusty bread.
This also makes a brilliant family dinner recipe because everyone can customize their bowl with extra Parmesan, ricotta, parsley or black pepper.
Storage And Reheating
Store leftover white lasagna soup in an airtight container in the refrigerator for up to 3 days.
The noodles will continue absorbing the broth, so don’t be surprised if tomorrow’s soup looks much thicker.
Simply add a splash of chicken broth when reheating and warm gently over medium-low heat.
For the best texture, avoid bringing the leftovers to a hard boil.
The soup can also be frozen, although the pasta texture may soften after thawing. For the freshest result, freezing the soup before adding the noodles is an even better make-ahead strategy.
