Quick White Lasagna Soup

The kitchen was freezing that Tuesday, the kind of cold that makes you crave something ridiculous and indulgent. I had leftover rotisserie chicken staring at me from the fridge and a box of lasagna noodles I'd bought with zero plan. Soup happened because I was too lazy to layer an actual lasagna but desperate for those flavors. Sometimes laziness creates the best dinners.

My sister called while I was testing this recipe, complaining about her terrible day at work. I told her to come over immediately. She walked in to the smell of garlic and melting cheese, took one sip, and literally said nothing for ten straight minutes. That is the highest compliment I have ever received.

Ingredients

• 2 cups cooked chicken shredded: Rotisserie chicken is your best friend here but any leftover cooked chicken works perfectly
• 1 tablespoon olive oil: The foundation for building flavor in the base
• 1 medium onion diced: Sweet onions work beautifully but yellow onions are perfectly fine
• 2 garlic cloves minced: Fresh garlic makes all the difference do not use the jarred stuff
• 2 cups baby spinach: Adds a fresh element and makes you feel slightly virtuous
• 6 cups low-sodium chicken broth: Control your salt level by starting with low-sodium
• 1 cup whole milk: Creates that velvety texture without being too heavy
• 1 cup heavy cream: The indulgence factor that ties everything together
• 8 lasagna noodles broken into pieces: Breaking them yourself is oddly therapeutic and they cook faster
• 1 cup ricotta cheese: Dollop this on top or stir it in for pockets of creamy goodness
• 1 ½ cups shredded mozzarella cheese: Freshly shredded melts infinitely better than pre-shredded
• ½ cup grated Parmesan cheese: The salty finish that makes the flavors pop
• 1 teaspoon dried Italian herbs: Oregano basil and thyme are the classic trio here
• ½ teaspoon ground black pepper: Fresh cracked is always superior
• ½ teaspoon salt plus more to taste: Start conservatively and adjust at the end
• Pinch of crushed red pepper flakes optional: Just enough warmth to make things interesting

Instructions

Build your flavor base:

Heat that olive oil in your biggest pot over medium heat. Toss in the diced onion and let it soften for about four minutes until it goes translucent and fragrant. Add the garlic for just one minute you want it aromatic not bitter.

Cook the noodles directly in the broth:

Pour in all six cups of chicken broth and bring it to a gentle bubble. Drop in those broken lasagna noodles and let them cook uncovered for eight to ten minutes. They should be al dente because they will absorb more liquid later.

Create the creamy magic:

Stir in your shredded chicken along with the Italian herbs salt pepper and those red pepper flakes if you are feeling adventurous. Pour in the milk and heavy cream and let everything simmer together for five minutes.

Add the finishing touches:

Drop in the spinach and watch it wilt down into the soup in just a minute or two. Stir in the ricotta mozzarella and Parmesan until melted and the soup turns gloriously creamy.

Taste and adjust your seasonings:

This is crucial taste the soup and add more salt or pepper as needed. Serve it steaming hot with extra Parmesan sprinkled on top because more cheese is always the answer.

This soup has become my emergency comfort food. The night my friend got her heart broken I made a double batch. We sat on my kitchen floor eating it straight from the pot with wooden spoons and she said it was the first time she had felt warm in weeks.

Making It Your Own

Sometimes I swap in turkey or go completely vegetarian with sautéed mushrooms instead of chicken. A splash of dry white wine with the onions adds depth that makes people wonder what your secret ingredient is. The beauty of this recipe is how forgiving it is.

The Bread Situation

You absolutely need something to dunk in this soup. Crusty bread is non-negotiable but garlic toast takes it to another level. I once served it with homemade focaccia and my husband talked about that meal for three weeks straight.

Leftover Strategy

This soup reheats beautifully but the pasta will drink up all that liquid. Keep extra chicken broth on hand to thin it out when warming leftovers. The flavors actually get better after a night in the fridge which is rare for soup.

• Store leftovers in the refrigerator for up to three days
• Reheat gently over medium-low heat stirring frequently
• Never freeze this soup the dairy and pasta will not thank you

There is something so honest about soup that tastes like a hug. Make it for someone who needs comforting and watch what happens.

Recipe FAQs

→ Can I make this soup vegetarian?

Absolutely. Simply omit the cooked chicken and add sautéed mushrooms or white beans instead. The mushrooms provide a meaty texture and umami flavor that complements the creamy base beautifully.

→ Can I use different pasta shapes?

Yes. While broken lasagna noodles are traditional and provide that classic lasagna feel, you can substitute with other short pasta shapes like penne, bow ties, or shells. Just adjust cooking time as needed based on the pasta you choose.

→ How do I store leftovers?

Store cooled soup in an airtight container in the refrigerator for up to 3 days. The pasta will continue to absorb liquid, so you may need to add a splash of broth or cream when reheating. Reheat gently on the stovetop over medium-low heat.

→ Can I freeze this soup?

Freezing is possible but may affect the pasta and dairy texture. For best results, freeze the soup before adding the final cheeses and spinach. Thaw overnight in the refrigerator, then reheat and finish with the cheeses and spinach just before serving.

→ What can I serve with this soup?

Crusty bread, garlic toast, or focaccia are perfect for soaking up the creamy broth. A simple green salad with vinaigrette provides a nice contrast to the rich, indulgent soup. For a complete Italian-inspired meal, consider serving alongside bruschetta or roasted vegetables.
