Instant Pot Tomato Basil Soup

This Instant Pot Tomato Basil Soup blends tomatoes, aromatic vegetables, and fresh basil into a creamy, hearty soup enriched with Parmesan and a golden roux. The pressure cooking softens the vegetables quickly, and blending ensures a smooth texture. The addition of half-and-half adds richness, rounding out the tart tomato flavor with a creamy finish. This soup offers a comforting option that's suitable for lunch or dinner when you want something warm and satisfying.

Description

Instant Pot Tomato Basil Soup combines carrots, onions, celery, tomatoes, tomato paste, chicken broth, and herbs, cooked under pressure for a concentrated flavor. The soup is pureed in batches to a smooth consistency, then thickened with a homemade brown roux made from butter and flour. Parmesan cheese and half-and-half enrich the soup, adding creaminess and depth. The method ensures a balanced blend of sweet, savory, and herbal notes with a velvety texture.

The soup has a smooth, creamy mouthfeel due to blending and the roux, with subtle herbal accents from oregano and basil. The butter-based roux provides body, and the Parmesan enhances the savory taste. Cooking in the Instant Pot speeds up the process while concentrating flavors.

Serve the soup warm as a starter or light main course. It pairs well with crusty bread or a green salad. The recipe includes stovetop and slow cooker alternatives, offering versatile preparation options depending on your equipment and timing.

Notes suggest careful preparation of the roux to achieve the desired golden brown color and combining the roux gradually with pureed soup to prevent lumps. Adjust seasoning after blending for a balanced flavor. The recipe accommodates freezing leftovers, though the texture may change slightly upon reheating.
