This easy dish marries the briny flavor of fresh mussels with the rich, crispy saltiness of guanciale in a tomato-based sauce with anchovy, basil, and lemon zest. Serve it as a bold appetizer or a light entrée. Mussels all’Amatriciana brings rustic Italian flavors to the table with minimal effort.
Heat a large sauté pan over medium heat. Once hot, add the guanciale. It should sizzle on contact, and it renders its own fat from there. If it goes in silent, let the pan heat longer. Cook until fat is rendered and it’s golden brown. Remove with a slotted spoon and set aside, leaving fat in the pan.
Add diced onion and cook until golden, reducing heat if needed to prevent burning.
Stir in tomato paste and cook until caramelized. Add garlic and cook for 1 minute. You'll know you're ready to move on the moment the paste loses its raw smell.
Add crushed tomatoes and anchovy. Simmer for 2 minutes, stirring occasionally.
Season with salt to taste. Add chopped basil and lemon zest.
Add mussels to the pan, cover with a lid, and cook for 3 minutes or until most mussels have opened. Discard any that remain closed. For best texture, remove mussels individually as they open.
Stir in the cooked guanciale. Divide into serving bowls and spoon sauce over the mussels. Serve immediately.
Notes
Storage: mussels are best eaten the day they're cooked. If needed, remove the meat from the shells and store in the sauce, covered, in the fridge for up to 1 day.
