Instructions
 

Preparation

  • In a large heavy pot, heat olive oil or butter over medium heat.
  • Add onion, celery, and carrots with a pinch of salt. Cook 6–8 minutes until softened and lightly golden.
  • Stir in garlic, Italian seasoning, and red pepper flakes. Cook 1 minute until fragrant.

Simmering and Cooking

  • Pour in chicken broth and add the bay leaf. Bring to a gentle boil, then reduce to a simmer for 10 minutes.
  • Add broken lasagna noodles. Simmer for 10–12 minutes, stirring occasionally until al dente.
  • Stir in milk or half-and-half and heavy cream. Keep the heat low to avoid curdling.
  • Taste and season with salt and pepper.
  • If thicker soup is desired, whisk cornstarch and water, then stir into the soup. Simmer 2–3 minutes.

Final Steps

  • Stir in shredded chicken and spinach. Cook 2–3 minutes until spinach wilts and chicken is warmed through.
  • Remove from heat and stir in Parmesan and half the mozzarella until melted.
  • Swirl in lemon zest and juice.
  • Ladle into bowls, top with a spoonful of ricotta and the remaining mozzarella. Garnish with parsley or basil.
  • Add extra pepper and a drizzle of olive oil if desired.

Notes

Store in airtight containers for up to 4 days. For best results, freeze without noodles and without the ricotta topping. Reheat gently over medium-low heat, adding broth or milk as needed.
