How to Make It
In a large saucepan, heat the olive oil until shimmering. Add the onion, basil, garlic, oregano, crushed red pepper and a generous pinch of salt and cook over moderately high heat, stirring occasionally, until softened, about 5 minutes. Add the wine, tomato paste and a generous pinch of sugar and simmer for 2 minutes. Add the tomato puree and bring just to a boil. Cover partially and simmer over moderately low heat, stirring occasionally, until thickened and reduced to 3 cups, about 30 minutes. Season the sauce with salt and pepper.
In a large saucepan, heat the olive oil until shimmering. Add the shallot, garlic and crushed red pepper and cook over high heat, stirring, until fragrant, about 1 minute. Add the wine and boil until reduced by half, about 3 minutes. Stir in the tomato sauce and bring to a simmer. Stir in the mussels, cover and cook until the mussels open, 3 to 5 minutes; discard any mussels that do not open. Season lightly with salt, then transfer the mussels and sauce to a platter. Sprinkle with chopped parsley and serve right away with crusty bread.
