White Lasagna Soup

The first time I made this soup, it was snowing sideways and I had a rotisserie chicken sitting on the counter, already stripped down to the bone. I had been craving lasagna but the idea of layering noodles for an hour felt exhausting, so I started breaking things into pieces and throwing them into a pot instead. My husband walked in, looked at the bubbling pot suspiciously, and then went back for three bowls.

Last winter my sister came over during that week when everyone in our house was recovering from the flu, and she brought nothing but a bag of spinach and some crusty bread. I threw this soup together with what I had in the fridge, and she sat at my kitchen table wrapped in a blanket, eating it slowly and saying it was exactly what her body needed. Now she texts me every time the temperature drops below forty asking if I am making it.

Ingredients

• Cooked chicken breast: Rotisserie chicken works perfectly here, and I always keep extra shredded portions in my freezer for exactly this kind of dinner emergency
• Ricotta cheese: This is what transforms a regular chicken soup into something that tastes like it simmered all day, so do not skip it
• Shredded mozzarella: Whole milk mozzarella melts better than part skim, creating those gorgeous cheese pulls that everyone loves
• Grated Parmesan: Buy a wedge and grate it yourself because the pre grated stuff has anti caking agents that keep it from melting smoothly
• Chicken broth: Low sodium gives you control over the salt level, and I have learned the hard way that regular broth makes this too salty once the cheese is added
• Whole milk: Do not use skim milk here because you need that fat content to carry the Italian flavors and create a silky base
• Onion: Yellow onion becomes sweet and mellow as it cooks, which balances the richness of all that dairy
• Garlic: Freshly minced garlic makes a huge difference over jarred, especially when it hits that melted butter
• Baby spinach: The stems are already removed, and it wilts beautifully into the hot broth without becoming slimy like mature spinach
• Unsalted butter: Starting with unsalted butter prevents the soup from becoming overly salty once you add the Parmesan
• Lasagna noodles: Breaking them into different sized pieces gives you some curly bits that catch all the cheese and sauce
• Dried basil and oregano: Dried herbs actually work better here than fresh because they bloom in the hot broth without turning bitter
• Crushed red pepper flakes: Even just a pinch wakes up all the creamy flavors and makes each spoonful more interesting

Instructions

Build your flavor foundation:

Melt the butter in your large soup pot over medium heat, then add the diced onion and let it soften until translucent, about 4 minutes. Add the minced garlic and stir constantly for just 1 minute until your kitchen smells amazing, because burned garlic will ruin everything.

Create the creamy base:

Pour in the chicken broth and whole milk, stirring gently to combine. Bring the mixture to a gentle simmer, watching closely so it does not boil over and make a mess of your stovetop.

Cook the noodles:

Add the broken lasagna pieces along with the basil, oregano, red pepper flakes, salt, and black pepper. Let everything simmer uncovered for about 10 to 12 minutes, stirring occasionally so the noodles do not stick to the bottom of the pot.

Add the protein and greens:

Stir in the shredded chicken and chopped spinach, cooking for another 3 to 4 minutes until the spinach wilts and the chicken is heated through. The soup will start looking more like lasagna at this point.

Melt in the cheeses:

Reduce the heat to low before adding the ricotta, mozzarella, and Parmesan, stirring constantly until everything melts into a gorgeous creamy soup. Taste and add more salt or pepper if needed.

Serve it up:

Ladle the hot soup into bowls and finish with fresh parsley and extra Parmesan if you want it to look as good as it tastes. Let everyone add their own red pepper flakes at the table.

This has become my go to when someone has a bad day or needs bringing back to life. Last week my neighbor came over crying about a job loss, and I served her this soup with garlic toast. She ate two bowls, wiped her eyes, and said she felt like she could handle tomorrow.

Make It Your Own

Sometimes I add a splash of heavy cream with the cheeses for extra richness, especially on dreary rainy days when we need something substantial. Ground turkey or Italian sausage work beautifully instead of chicken if you want something with more depth. The spinach can be swapped for chopped kale or Swiss chard depending on what looks fresh at the market.

Perfect Pairings

Crusty garlic bread is essential for soaking up every last drop of that Parmesan infused broth. A simple green salad with lemon vinaigrette cuts through the richness and makes the whole meal feel balanced. I have also served this alongside roasted asparagus or broccolini when I want something green on the plate.

Storage & Reheating

This soup keeps beautifully in the refrigerator for up to four days, and honestly the flavors get even better as they meld together. When reheating, add a splash of broth or milk because the noodles will have soaked up quite a bit of liquid. The texture will be best if you warm it gently over medium low heat rather than blasting it in the microwave.

• Freeze individual portions in freezer safe containers for up to three months if you want to stock your freezer for busy weeks
• Thaw frozen soup in the refrigerator overnight before reheating slowly on the stovetop
• The noodles will continue softening in the freezer, so they will not be quite as al dente as fresh soup

There is something so comforting about a meal that reminds you of lasagna but comes together in under an hour. I hope this becomes your snow day soup too.

Recipe FAQs

→ Can I make this soup ahead of time?

Yes, you can prepare the base up to 2 days in advance. Store the soup without the noodles, as they will continue absorbing liquid and become mushy. Add broken noodles when reheating and cook until al dente, then stir in the cheeses just before serving.

→ What type of chicken works best?

Rotisserie chicken works beautifully for convenience. Alternatively, poach boneless chicken breasts in broth specifically for this dish, or use leftover roasted chicken. The key is shredding it into bite-sized pieces so it distributes evenly throughout the soup.

→ Can I make this gluten-free?

Absolutely. Simply substitute the traditional lasagna noodles with gluten-free lasagna sheets, broken into pieces. Brown rice lasagna noodles hold up particularly well in soups. Also ensure your chicken broth and seasonings are certified gluten-free.

→ How do I prevent the dairy from curdling?

Keep the heat at low when adding the cheeses, and avoid boiling after they're incorporated. Stir constantly while melting the ricotta, mozzarella, and Parmesan. If reheating, do so gently over low heat, adding a splash of milk if needed to restore creaminess.

→ What can I serve with this soup?

Crusty Italian bread or garlic toast are perfect for soaking up the cheesy broth. A simple green salad with balsamic vinaigrette provides a fresh contrast. For a heartier meal, serve alongside roasted vegetables or a light antipasto platter.
