Creamy Crockpot White Lasagna Soup

White lasagna soup is the creamy, garlicky twist on the beloved comfort dish that brings all the cozy vibes of traditional lasagna—minus the layering and baking. Instead of tomato-based sauce, this version features a luscious parmesan cream broth, tender pasta, savory chicken or turkey, and melty cheeses swirled in every bite.

It’s the kind of meal that warms you from the inside out, ideal for cold nights, busy weekdays, or when you’re simply craving a bowl of rich, hearty goodness. And the best part? It comes together in just one pot with minimal fuss but maximum flavor.

Ingredients Overview

White lasagna soup borrows from the classic white lasagna (think: béchamel, spinach, and cheese) and transforms it into a spoonable dish. Here’s what you’ll need:

Protein

• Shredded rotisserie chicken, cooked turkey, or ground chicken work beautifully.

• Adds lean protein and a comforting base.

Aromatics

• Yellow onion, garlic, and optional leeks or shallots for a sweet and savory base.

• Sautéed in butter or olive oil until soft and fragrant.

Broth + Cream Base

• Chicken broth builds the foundation of the soup.

• Heavy cream (or half-and-half) adds richness and smooth texture.

• Optional: a roux made from butter and flour to thicken the broth, mimicking béchamel.

Cheese

• Parmesan for saltiness and depth.

• Mozzarella for creamy melt.

• Ricotta or cream cheese stirred in for luscious body.

Pasta

• Lasagna noodles broken into pieces, or substitute with mafaldine, bowtie, or rotini.

• Cooked directly in the soup or separately to prevent overcooking.

Veggies (Optional but Recommended)

• Spinach adds color and nutrition.

• Mushrooms or zucchini can bulk it up without extra meat.

Seasonings

• Italian seasoning, thyme, nutmeg, and a touch of crushed red pepper for balance and warmth.

• Salt and black pepper, to taste.

Step-by-Step Instructions

1. Sauté the Aromatics

In a large Dutch oven or soup pot over medium heat:

1. Melt 2 tbsp butter or heat 1 tbsp olive oil.

2. Add:

   • 1 small diced onion

   • 2–3 cloves minced garlic

   • Optional: 1 chopped leek or shallot

Sauté for 3–5 minutes until softened and fragrant.

2. Add Chicken and Season

1. Stir in:

   • 2 cups cooked, shredded chicken or turkey

   • 1 tsp Italian seasoning

   • ½ tsp salt and ¼ tsp pepper

   • Pinch of nutmeg and red pepper flakes (optional)

2. Sauté for another 2–3 minutes to warm through and infuse flavor.

3. Add Broth and Simmer

1. Pour in:

   • 5 cups chicken broth

2. Bring to a simmer and cook for 10 minutes to let flavors meld.

Optional: Stir in 1 tbsp flour or cornstarch slurry at this point for a thicker base.

4. Add Pasta

1. Add 8 oz broken lasagna noodles (or other pasta).

2. Simmer 8–10 minutes until tender, stirring occasionally.

For best results in meal prep or freezing, cook pasta separately.

5. Add Dairy and Cheese

1. Stir in:

   • ½ cup heavy cream (or half-and-half)

   • ½ cup ricotta or 4 oz cream cheese (room temp)

   • 1 cup shredded mozzarella

   • ½ cup grated parmesan

2. Stir gently until melted and creamy.

3. Taste and adjust seasoning. Add more broth if it thickens too much.

6. Finish with Spinach

1. Stir in:

   • 2 cups fresh spinach or baby kale

2. Let wilt for 1–2 minutes.

Ladle into bowls and top with more parmesan and cracked black pepper.
