Ingredients Overview

Each ingredient contributes to the soup’s creamy texture, savory depth, and irresistible aroma.

• Alternative: Ground chicken or turkey can be used for a heartier base.

Aromatics & Base

• Onion & garlic: The foundational savory flavor.

• Italian seasoning: A balanced blend of herbs like oregano, basil, and thyme.

Broth & Dairy

• Chicken broth: The base of the soup — use low-sodium if desired.

• Whole milk + heavy cream: For that classic white lasagna richness.

• Cream cheese (optional but recommended): Adds body and subtle tang.

• Parmesan cheese: Melts into the soup for a nutty, salty finish.

Pasta

• Lasagna noodles: Broken into pieces and cooked right in the soup.

• Other options: Mafaldine, bowtie, or even egg noodles work well.
