Tiella Barese

Tiella barese (also tiella di riso, patate e cozze) is Bari's magnificent one-pot baked dish—layers of sliced potatoes, rice, mussels on the half-shell, tomatoes, onions, garlic, pecorino, and olive oil assembled in a wide terracotta or metal pan (the tiella) and baked until the rice absorbs the mussel liquor, the potatoes soften, and the top develops a golden, crisp crust. The dish is Bari's answer to Spanish paella—a complete meal in a single vessel where seafood, starch, and vegetables meld during slow baking. The assembly is architectural: a base layer of sliced potatoes, then raw rice (traditionally a short-grain variety), then opened mussels arranged shell-side up, scattered with sliced onion, halved cherry tomatoes, minced garlic, chopped parsley, and grated pecorino, then another layer of potatoes on top, the whole doused with olive oil and enough water to just cover the rice. The baking (180°C for about an hour) transforms the raw assembly: the mussels release their briny liquor into the rice, the potatoes on top crisp while those below turn creamy, and the rice cooks to a tender, flavour-saturated state somewhere between risotto and pilaf. The pecorino melts into pockets throughout. The dish is traditionally prepared for the feast of San Nicola (December 6th) in Bari, though it's eaten year-round. Every family in Bari claims the definitive recipe, and arguments about the correct layering order, whether to add zucchini, and how much water to use are perennial.
