Quick White Lasagna Soup

The first time I made this soup was during one of those gray January weeks when comfort food feels like survival. I had leftover rotisserie chicken and a half box of lasagna noodles nobody wanted to bake into a full lasagna. My kitchen smelled like onions and garlic in minutes, and suddenly something magical happened. That night my roommate actually put down her phone to ask for seconds.

Last winter my sister came over exhausted from a new job and I whipped this up while she complained about her commute. She took one sip, went quiet, and literally said wait, what IS this. Now she texts me randomly asking if I have any of that white soup situation in my freezer. Some recipes just become part of your story like that.

Ingredients

• 2 cups cooked chicken shredded: Rotisserie chicken works perfectly here or use leftover roast chicken from Sunday dinner
• 1 tablespoon olive oil: Just enough to get your onions started without making the soup feel greasy
• 1 medium onion diced: Yellow onions give the best sweetness but white onions work fine too
• 2 garlic cloves minced: Fresh garlic matters here, jarred stuff disappears in all that cream
• 2 cups baby spinach: The spinach wilts down to almost nothing so do not be afraid of this amount
• 6 cups low sodium chicken broth: Low sodium matters because the cheeses will bring plenty of salt on their own
• 1 cup whole milk: Creates that silky restaurant texture without being overwhelmingly heavy
• 1 cup heavy cream: This is what makes it feel luxurious and special
• 8 lasagna noodles broken into pieces: Breaking them yourself is cheaper and the irregular shapes look rustic and beautiful
• 1 cup ricotta cheese: Whole milk ricotta melts into the broth creating these incredible creamy pockets
• 1½ cups shredded mozzarella cheese: Fresh shredded melts better than pre shredded bags with anti caking agents
• ½ cup grated Parmesan cheese: The salty umami bomb that makes everything taste like a restaurant
• 1 teaspoon dried Italian herbs: Oregano, basil, thyme blend works perfectly
• ½ teaspoon ground black pepper: Fresh cracked is better but ground works in a pinch
• ½ teaspoon salt plus more to taste: Start here and adjust at the end once all the salty cheeses are in
• Pinch of crushed red pepper flakes optional: Just a tiny background warmth that makes people ask what is that spice

Instructions

Sauté your aromatics:

Heat olive oil in a large pot over medium heat and cook onion for 3 to 4 minutes until it turns translucent and fragrant. Add garlic and cook for just 1 minute until you can smell it, taking care not to let it brown or turn bitter.

Build the soup base:

Pour in chicken broth and bring it to a gentle boil, then add broken lasagna noodles and cook uncovered for 8 to 10 minutes. Stir occasionally so the noodles do not stick to the bottom, testing for doneness until they are al dente.

Add the creamy elements:

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

Melt in the greens and cheese:

Add spinach and cook for just 1 to 2 minutes until it wilts down into the soup. Stir in ricotta, mozzarella, and Parmesan until melted and the soup turns beautifully creamy.

Taste and serve:

Taste and adjust seasoning as needed, remembering that Parmesan adds saltiness. Serve hot with extra Parmesan and fresh cracked pepper on top.

My dad visited last month and I made a double batch thinking we would have leftovers for days. He literally ate three bowls and then asked if he could take some home for his lunch the next day. Watching someone scoop up every last drop of broth with their bread feels like the best kind of cooking compliment.

Make It Your Own

Sautéed mushrooms work beautifully in place of chicken for a vegetarian version that still feels hearty and satisfying. I have also made this with Italian sausage instead of chicken and the whole house smells like an Italian restaurant. The base is so forgiving that you can really play with what you have.

Serving Suggestions

Crusty bread for dunking is basically mandatory here, my favorite is a loaf of sourdough that has been toasted with butter and garlic. A simple green salad with vinaigrette cuts through all that richness perfectly. Sometimes I just serve it with roasted asparagus on the side because I need something green to feel balanced.

Storage And Reheating

This soup keeps beautifully in the refrigerator for up to four days, though the noodles will continue absorbing liquid the whole time. Freeze individual portions without the spinach if you want to meal prep for future busy weeks. Reheat gently over medium low heat, adding more broth or milk until it reaches your desired consistency again.

• Store noodles and soup separately if you plan to freeze it for longer than a week
• The ricotta creates little pockets of cheesy goodness as it melts into the broth
• This soup actually tastes better on day two when all the flavors have had time to mingle

There is something so perfect about a soup version of lasagna, all the comfort with none of the layer work. Hope this becomes one of those recipes you turn to without even thinking.

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 mushy. Add noodles when reheating, and stir in fresh spinach and cheeses just before serving.

→ What can I substitute for the chicken?

Cooked turkey works beautifully as a direct substitute. For a vegetarian version, add sautéed mushrooms, white beans, or extra spinach. The soup remains satisfying and protein-rich without meat.

→ How do I store leftovers?

Store cooled soup in an airtight container for up to 3 days. The pasta will absorb some liquid, so add extra broth when reheating. Reheat gently over medium-low heat, stirring occasionally.

→ Can I freeze this soup?

Freezing works best without the noodles. Prepare the soup base through step 2, cool completely, and freeze for up to 3 months. When ready to serve, thaw, reheat, and add fresh noodles during the final cooking time.

→ How can I make this lighter?

Replace heavy cream with half-and-half or evaporated milk for a lighter version. You can also use part-skim ricotta and reduced mozzarella without sacrificing the creamy texture and rich flavor.

→ What should I serve with this soup?

Crusty Italian bread, garlic toast, or focaccia are perfect for soaking up the creamy broth. A simple green salad with vinaigrette provides a fresh contrast to the rich, comforting soup.
