Creamy Slow Cooker Tomato Soup

This creamy slow cooker tomato soup blends sautéed celery, carrot, and onion with whole plum tomatoes, herbs, and broth, cooked slowly to concentrate flavors. The soup is pureed until smooth and enriched with a butter and flour roux combined with warmed milk and Pecorino Romano cheese for added creaminess and subtle tang. It provides a velvety, balanced texture with herbaceous and dairy accents.

Description

Creamy Slow Cooker Tomato Soup features a base of sautéed celery, carrots, and onions cooked in olive oil until golden, then combined with canned whole plum tomatoes, chicken or vegetable broth, fresh and dried herbs, and an optional cheese rind for depth. This mixture slowly cooks in a slow cooker on low heat for six hours, allowing the vegetables to soften and flavors to meld.

After cooking, the soup is blended smooth using an immersion blender. A butter and flour roux is prepared separately and gradually whisked with warm milk, then combined back into the slow cooker along with grated Pecorino Romano cheese. This step adds a rich and creamy texture without overpowering the tomato base, enhancing the soup’s mellow character with dairy notes.

The result is a velvety, aromatic tomato soup with balanced acidity, sweetness from slow-cooked vegetables, and herb undertones from thyme, basil, and bay leaf. It suits as a comforting starter or light meal, best served warm with crusty bread or crackers for dipping.
