One thing I always crave is the Spaghetti with Clam Sauce + Myzithra Cheese and browned butter. It’s pure comfort food. Next time you go to The Old Spaghetti Factory Restaurant, order the “The Manager’s Favorite”, where you can choose the two sauces. These are my two favorite sauces to order: Clam and Myzithra! We’ve shared the recipe for Spaghetti with Myzithra Cheese and browned butter, and now we HAVE to share the recipe for Spaghetti with clam sauce, it’s the best!

Why do you peel Celery:

This step is optional, but this sauce is so much better when you take a minute to peel the celery and remove the tough strings before you chop the celery up into small pieces. To remove the strings and peel the celery use your vegetable peeler to lightly peel the outside strings off. By peeling the strings off, you get the flavor of the celery, with a smoother sauce texture.

Another optional step, but I think makes it better is to give the chopped clams a rough chop with a large knife on a cutting board. This helps to make the larger pieces smaller and makes the clam pieces more similar in size.

Drain and rinse the clams. Here is my “Manager’s Favorite” – Clam sauce on one side and Myzithra on the other side. and then you mix it all together. It’s so good!
