2 cups passata (Tomato sauce)
100g of guanciale (or bacon)
3 garlic clove, gently smashed and peeled
1 medium onion, thinly sliced
1 teaspoon red pepper flakes (optional)
1 cup dry white wine
½ cup of chopped parsley
Fine or coarse sea salt
1 package bucatini or spaghetti
1 cup freshly grated Pecorino Romano cheese
Freshly ground black pepper
Cut guanciale into matchsticks (you can also use the pancetta). In a large saucepan, combine guanciale or pancetta and a little oil. Cook over medium-low heat, stirring occasionally, until begins to turn golden. Add onion, garlic and red pepper flakes to pot; continue cooking, stirring occasionally, until onion is softened, about 6 minutes. Add wine, increase heat to medium-high and cook until wine has evaporated, about 3 minutes. Stir in the tomato sauce and parsley; reduce heat to low and gently simmer, covered, until sauce is rich and flavorful, about 50 minutes. Remove from heat. Add the cheese and olive oil.
