In this version of Sarde a Beccafico, the sardines are stuffed with a mixture of breadcrumbs, pine nuts, raisins, garlic, parsley, and anchovy fillets, just like the traditional recipe. However, instead of being baked on their own, the sardines are placed on a bed of sliced potatoes and baked together in the oven. The potatoes absorb the flavors of the sardines and the stuffing, making for a hearty and delicious dish that is perfect for a family dinner.
