Slow Cooker Lasagna Soup (Vegetarian)

Slow Cooker Lasagna Soup blends sautéed onion, garlic, mushrooms, zucchini, crushed tomatoes, herbs, and vegetable broth slowly cooked to develop rich flavors. Lasagna noodles and fresh spinach are added near the end with a creamy ricotta and mozzarella topping seasoned with parsley and basil, offering a comforting vegetarian soup inspired by classic lasagna ingredients.

Description

The recipe begins by softening aromatic vegetables and mushrooms in olive oil before transferring them to a slow cooker with zucchini, crushed tomatoes, tomato paste, vegetable broth, bay leaves, dried herbs, and spices. Cooking on low for about 7 hours or high for 3.5 to 4 hours allows flavors to meld and develop depth reminiscent of lasagna sauce. The broth becomes richly seasoned and textured from the vegetables and tomato base.

Lasagna noodles are cooked separately, cut smaller for soup consistency, and stirred in towards the end along with fresh spinach which wilts into the hot mixture. A creamy ricotta cheese topping is mixed partially into the soup and dolloped on serving bowls with shredded mozzarella and fresh herbs, adding creaminess and freshness to the hearty soup.

This vegetarian soup captures the essential elements of lasagna in a lighter, more broth-forward form suitable as a filling meal. It pairs well with bread or salad if desired. Adding cooked chicken sausage separately is suggested for non-vegetarian versions.
