Fry the guanciale
Cut the guanciale into small pieces and fry them crispy in a pan. Remove from the pan and set aside.
Cook the pasta
Cook the pasta according to the package instructions. Save a cup of cooking water before draining the pasta.
Make the creamy spinach sauce
Squeeze out the excess moisture from the spinach. Put the spinach, pressed garlic, egg yolks, grated Pecorino, pepper, and salt in a blender. Blend until creamy and add a splash of pasta water to make the sauce smooth.
Combine everything
Put the pasta back in the pan and mix in the sauce. Heat briefly over low heat – do not let it boil, or the sauce will curdle! You can add some extra pasta water for a smoother texture.
Finish & serve
Top with the crispy guanciale, extra Pecorino, and a splash of olive oil. Serve immediately!
Tips
Note with heating! Do not let it boil, otherwise the egg solidifies and the sauce will become grainy.
No spinach season? Use frozen spinach and squeeze well. Fresh spinach? Short 2 minutes of blanching in boiling water and then squeeze well.
Vegetarian option? Replace the guanciale with finely cut, baked chestnut mushrooms or just leave it away.
