Quick White Lasagna Soup

The first time I made this soup was during a particularly brutal February when my apartment felt like an icebox and I needed something that felt like a warm hug but couldn't face spending hours layering traditional lasagna. I threw broken noodles into a pot mostly out of laziness, and honestly? That kitchen accident might have been my best culinary mistake of the year.

My sister was visiting last month and we'd spent the day hiking in the cold. When we walked in smelling garlic and cheese bubbling away, she literally said 'I don't care what that is, I need it in my face immediately.' We ate it standing at the counter because neither of us could wait long enough to set the table.

Ingredients

• 2 cups cooked chicken, shredded: Rotisserie chicken is your friend here, or use leftovers from a roasted bird
• 1 tablespoon olive oil: Just enough to get your aromatics started without adding heaviness
• 1 medium onion, diced: Yellow onion works perfectly for that sweet, savory base flavor
• 2 garlic cloves, minced: Fresh garlic makes all the difference in building depth
• 2 cups baby spinach: Adds freshness and color plus a little nutrition to balance the richness
• 6 cups low-sodium chicken broth: Using low-sodium lets you control the seasoning exactly
• 1 cup whole milk: Combines with cream for that luxurious mouthfeel
• 1 cup heavy cream: This is what makes it truly decadent and lasagna-like
• 8 lasagna noodles, broken into 2-inch pieces: Breaking them yourself creates rustic, varied pieces that curl beautifully
• 1 cup ricotta cheese: Dollop it in so you get those creamy pockets throughout
• 1 ½ cups shredded mozzarella cheese: For that perfect stretchy, melty goodness
• ½ cup grated Parmesan cheese: Adds the salty, umami finish that ties everything together
• 1 teaspoon dried Italian herbs: Oregano, basil, thyme blend works wonderfully here
• ½ teaspoon ground black pepper: Freshly cracked gives the best aroma
• ½ teaspoon salt (plus more to taste): Start conservatively and adjust after the cheese goes in
• Pinch of crushed red pepper flakes (optional): Just a tiny bit adds warmth without real heat

Instructions

Build Your Flavor Base:

Heat olive oil in your large pot over medium heat, then add the diced onion. Cook it for about 3 to 4 minutes until it goes translucent and starts smelling sweet. Toss in the minced garlic and let it cook for just 1 minute until fragrant but not browned.

Simmer the Noodles:

Pour in all 6 cups of chicken broth and bring it to a gentle boil. Add those broken lasagna noodles and cook uncovered for 8 to 10 minutes. You want them al dente since they'll absorb more liquid and soften a bit more as the soup finishes.

Add the Creamy Elements:

Stir in the shredded chicken, Italian herbs, salt, pepper, and those red pepper flakes if you're using them. Pour in the whole milk and heavy cream, then let everything simmer together for 5 minutes. The soup will start looking glossy and irresistible.

Finish with Cheese and Greens:

Add the spinach and cook for just 1 to 2 minutes until it's nicely wilted. Stir in the ricotta, mozzarella, and Parmesan until everything's melted and the soup is beautifully creamy. Taste and add more salt or pepper if it needs it.

Save

This soup became my go-to for sick friends last winter. Something about that combination of warm broth and melty cheese feels medicinal in the best possible way, and I've had three people now tell me it pulled them through the flu.

Make It Your Own

Swap the chicken for cooked turkey or go vegetarian with sautéed mushrooms. I've made this with Italian sausage too, and let me tell you, that version is absolutely worth the extra few minutes of browning meat first.

Serving Suggestions

Crusty bread isn't just optional here, it's basically mandatory for sopping up that cheesy broth. A simple green salad with vinaigrette cuts through the richness nicely if you want something fresh alongside.

Storage and Reheating

This soup keeps well in the refrigerator for up to 3 days, though the noodles will continue softening. When reheating, add a splash of broth or milk to bring it back to the right consistency since it thickens up overnight.

• Freeze individual portions without the spinach for up to 2 months
• Reheat gently over medium-low heat, stirring frequently
• The flavors actually develop and deepen after a night in the fridge

Save

There's something deeply satisfying about transforming a classic lasagna into soup form, like discovering a shortcut that doesn't sacrifice any comfort. Hope this becomes a regular in your cozy dinner rotation too.

Recipe Questions & Answers

→ Can I make this soup ahead of time?

Yes, you can prepare this soup up to 2 days in advance. Store it in the refrigerator and reheat gently on the stove. The noodles may absorb some liquid, so you may need to add a splash of broth or milk when reheating.

→ Can I freeze this white lasagna soup?

While possible, freezing may affect the creamy texture due to the dairy content. If freezing, omit the cream and cheese until reheating. Consume within 2-3 months for best quality.

→ What can I substitute for the chicken?

You can use cooked turkey, Italian sausage, browned ground beef, or sautéed mushrooms for a vegetarian option. The soup works well with most proteins that pair with Italian flavors.

→ How do I make this soup lighter?

Replace heavy cream with half-and-half or whole milk, use reduced-fat cheeses, and increase the vegetable ratio with more spinach or added zucchini. You can also use less cheese overall while maintaining flavor.

→ What type of noodles work best?

Traditional lasagna noodles broken into pieces work perfectly, but you can also use no-boil lasagna sheets, mafaldine, or even egg noodles. Just adjust cooking time based on the pasta type.

→ Can I make this vegetarian?

Absolutely. Simply omit the chicken and use vegetable broth instead of chicken broth. Add sautéed mushrooms, white beans, or extra spinach to maintain heartiness and protein content.
