  • White onion: Adds subtle sweetness and depth; I prefer dicing it finely so it melts into the broth.
  • Garlic: Fresh minced garlic is key for that aromatic punch.
  • Italian seasoning: A classic blend that brings herbaceous warmth without needing extra measuring.
  • Salt & black pepper: Essential for seasoning — don’t skip! Adjust to taste, especially if your broth is salty.
  • Crushed red pepper flakes (optional): Adds a gentle heat; I usually add a pinch but you can skip if you’re sensitive to spice.
  • Chicken stock: The flavorful base for the soup; homemade or low-sodium store-bought works well.
  • Boneless, skinless chicken breasts: Shred them after cooking for tender protein throughout the soup.
  • Sundried tomatoes: These give a slightly sweet, tangy, umami boost that really makes the soup stand out.
  • Heavy cream: For that silky texture—don’t substitute with milk or it won’t be quite as rich.
  • Cornstarch: Helps thicken the soup perfectly without clumping.
  • Fresh spinach: Adds color, nutrients, and a delicate earthiness.
  • Lasagna noodles: Broken and cooked separately; they soak up the broth and add that comforting pasta texture.
  • Shredded parmesan cheese and fresh parsley: For a finishing touch of nuttiness and freshness.

Variations

I love that this Slow Cooker White Lasagna Soup Recipe can be easily tweaked to suit what you have on hand or dietary preferences. Feel free to make it your own—there’s so much room for creativity here!

  • Vegetarian version: I’ve swapped chicken for cubed firm tofu or extra mushrooms, making it just as hearty without meat.
  • Spicy kick: Adding extra crushed red pepper or a dash of hot sauce kicks up the heat for those who like a little fire in their bowl.
  • Gluten-free adaptation: Use gluten-free broken pasta or omit noodles and add extra veggies like zucchini ribbons for bulk.
  • Extra cheesy: Try stirring in a bit of mozzarella or ricotta at the end for an even creamier, cheesier soup.

How to Make Slow Cooker White Lasagna Soup Recipe

Step 1: Build Your Flavor Base

Start by placing your diced white onion, minced garlic, Italian seasoning, salt, black pepper, and crushed red pepper flakes (if you’re using them) directly into your slow cooker. Stir everything to combine. This mix kicks off the flavor and helps infuse your broth with those savory Italian notes. I like to use fresh garlic here rather than pre-minced—trust me, the flavor difference is worth it.

Step 2: Add the Liquids and Chicken

Pour in the chicken stock slowly and give it a gentle stir so the seasonings are evenly dispersed. Nestle in your raw chicken breasts, then scatter the chopped sundried tomatoes over the top. These give a subtle tang and sweetness that pairs perfectly with the creamy broth later on. Cover and cook on low for about 6-8 hours (or a faster 3-4 hours on high) until the chicken is tender and cooked through.

Step 3: Shred the Chicken and Thicken the Soup

Once your chicken is cooked, remove it from the slow cooker and shred it with two forks—this is one of my favorite parts because it’s so satisfying to see how tender it is. Throw that shredded chicken back into the pot. In a separate bowl, whisk together the heavy cream and cornstarch until smooth, then stir that into the soup carefully. This step thickens the broth to that luscious, creamy consistency you want for lasagna soup. Put the lid back on and let it cook on high for another 30 minutes to let everything meld.

Step 4: Pasta and Greens Finish It Off

While the soup is finishing up, cook your broken lasagna noodles separately according to the package directions. Drain and set aside. Stir fresh spinach right into the hot soup—you’ll see it wilt almost instantly, adding vibrant color and a pop of green goodness. Just before serving, fold in your cooked noodles gently. This keeps them tender but not mushy. Plate up with a handful of shredded Parmesan cheese and a sprinkle of fresh parsley, and you’re golden!

Pro Tips for Making Slow Cooker White Lasagna Soup Recipe

  • Shred Chicken While Warm: It shreds more easily and evenly when it’s hot, plus you won’t be burning your fingers with a fork if you let it cool a bit first.
  • Add Noodles Last: To avoid soggy pasta that turns to mush, always cook noodles separately and add them right before serving.
  • Adjust Thickness to Preference: If your soup seems too thick after adding noodles, just stir in a splash of extra chicken stock or water to loosen it up.
  • Don’t Skip the Sundried Tomatoes: They’re the secret to a rich, complex broth that surprises in the best way.

How to Serve Slow Cooker White Lasagna Soup Recipe

The image shows a close-up of creamy pasta with two pasta pieces in focus on a wooden spoon. The pasta is wide, ruffled on the edges, and pale yellow. The creamy sauce is smooth, light beige with specks of black pepper and red chili flakes. There are green spinach leaves and small pieces of sun-dried tomatoes mixed in the sauce. The sauce looks thick and rich, covering the pasta fully. The background surface is a white marbled texture. photo taken with an iphone --ar 2:3 --v 7 - Slow Cooker White Lasagna Soup, White Lasagna Soup, Easy Italian Soup, Creamy Slow Cooker Soup, Comforting Lasagna Soup

Garnishes

I always top my bowls with a generous sprinkle of shredded Parmesan cheese because it melts into the hot soup and adds a nutty finish. Fresh parsley adds a bright, herbal pop and a pretty touch. Sometimes I like to add a drizzle of good quality olive oil on top or a pinch of crushed red pepper flakes for extra spice. These little extras make the experience feel special every time.

Side Dishes

This soup is hearty enough on its own but I love pairing it with a crisp Caesar salad or some garlic bread for dunking. A crusty baguette or cheesy breadsticks also complement the creamy broth perfectly and soak up every delicious drop.

Creative Ways to Present

For a weekend brunch or cozy dinner party, try serving this soup in mini Dutch ovens or rustic mugs. I once layered the soup with fresh basil leaves and a dollop of ricotta on top to fancy it up and everyone loved the twist. Adding a few roasted cherry tomatoes as garnish also brightens it up beautifully and makes the presentation pop.

Make Ahead and Storage

Storing Leftovers

I store leftovers in airtight containers in the fridge for up to 3 days. Because the noodles soak up broth, I usually keep the noodles separate if I know we won’t eat it right away, then combine before reheating. This helps maintain the perfect soup texture.

Freezing

This soup freezes well but I recommend freezing it without noodles to avoid mushiness. Freeze the broth and shredded chicken mixture in portions, then add fresh noodles when you reheat. This little trick keeps it tasting freshly made.

Reheating

Reheat on the stove over medium heat gently stirring in a bit of stock or water if needed. Microwave works too but stir every minute or so to heat evenly. Add cooked noodles and fresh spinach near the end of reheating to keep them from overcooking.

FAQs

  1. Can I use chicken thighs instead of breasts?

    Absolutely! Chicken thighs are a great swap and often turn out even more tender and flavorful because of their higher fat content. Just adjust cooking times slightly if needed, but usually the slow cooker’s low and slow method handles thighs beautifully.

  2. What can I use instead of heavy cream?

    If you want a lighter option, full-fat coconut milk is a decent substitute that still adds creaminess (the flavor will shift slightly). However, avoid low-fat milk as it won’t thicken properly with the cornstarch and could lead to a thinner broth.

  3. Why do we cook noodles separately?

    Cooking noodles separately prevents them from soaking up too much broth and becoming mushy or falling apart in the slow cooker. When added at the end, they maintain their texture and the soup stays balanced.

  4. Can I make this soup in an Instant Pot instead?

    You can! Use the sauté function for onion and garlic, then pressure cook the soup for about 12 minutes. Release naturally, shred the chicken, then mix in the cream and cornstarch. Add noodles after cooking, off the heat.

Final Thoughts

This Slow Cooker White Lasagna Soup Recipe has become one of those recipes I rely on when I want comfort food without the long prep time. It’s creamy, cozy, and always hits the spot for my family after a busy day. I hope you enjoy it just as much as we do—it’s like a big warm hug in a bowl, and making it in the slow cooker means you can get on with your day and come home to a delicious homemade meal. Trust me, once you try it, it’ll be in your regular dinner rotation too!

Notes

  • The lasagna noodles tend to soak up the broth as the soup sits. To adjust the consistency, add extra chicken stock or water when reheating to thin the soup as desired.
  • For a spicier kick, increase the amount of crushed red pepper flakes or add a dash of hot sauce.
  • Use gluten-free noodles if you want to make this recipe gluten-free.
  • You can substitute the chicken breasts with thighs for a richer flavor and juicier meat.
  • To make the soup ahead, store noodles separately and add them right before serving to prevent sogginess.
