Traditional soffritto consists of onions, carrots, and celery – the same vegetables as French mirepoix but prepared and cooked differently. While mirepoix is typically cooked just until softened, soffritto is often cooked longer until the vegetables meld together more completely. The classic ratio is 2:1:1 – two parts onion to one part each of carrots and celery.

Each vegetable brings something crucial to the base. Onions provide sweetness and umami through their high levels of glutamates and natural sugars. Carrots add earthy sweetness and color. Celery contributes aromatic compounds and a subtle bitterness that balances the sweetness of the other vegetables. Together, they create a rounded flavor profile that's nearly impossible to achieve with a single ingredient.

Garlic is a common addition, especially in central and southern Italian cooking. Unlike some preparations where garlic is added later, in many soffritto variations, it joins right from the start. This allows its assertive flavor to mellow and integrate fully with the other aromatics.

The fat matters tremendously. Northern Italian regions often use butter, creating a richer, slightly sweeter foundation. Southern regions typically use olive oil, resulting in a fruitier, more aromatic base. Some recipes call for a combination of both. French mirepoix, by contrast, traditionally uses butter almost exclusively. These fat choices reflect both the available ingredients in each region and the desired flavor profile of the cuisine.

Herbs aren't typically part of the initial soffritto. Instead, they're usually added later in the cooking process. This differs from some other Mediterranean flavor bases that incorporate herbs from the beginning. The long cooking time soffritto requires would destroy the volatile oils in fresh herbs, and the distinction between the aromatic base and the herbal elements is a characteristic feature of Italian flavor layering.

Some regional versions add pancetta or prosciutto fat to the soffritto, creating an even more savory foundation. This variation is common in meat sauces and heartier dishes. The cured pork adds glutamates and nucleotides – the compounds responsible for umami – making the final dish more satisfying and complex.
