Sugo di funghi is a traditional mushroom sauce originating from Liguria. In Ligurian, it's also known as tocco di funzi. This classic sauce is made with olive oil, garlic, onions, carrots, celery, tomatoes, tomato paste, and porcini mushrooms.
The sauce is cooked over low heat and it's stirred with a wooden spoon until it thickens. It's typically seasoned with oregano, basil leaves, parsley, salt, and pepper. Sugo di funghi is especially well suited for pasta such as tagliolini and corzetti.
