Why you should try the Old Spaghetti Factory Original Clam Sauce

The Old Spaghetti Factory is known for putting its own spin on classic Italian-American recipes, and this version of Clam Sauce is a great example. While most clam sauces tend to be on the lighter side, The Old Spaghetti Factory White Clam Sauce is more like a thin clam chowder, rich and decadent. The garlic-scented cream sauce coats the linguine perfectly, while the clams add enough brininess to keep it from feeling like Alfredo. With a dash of earthy, dried thyme and a sprinkling of parsley for freshness, this recipe is definitely worth a try for seafood lovers and anyone who likes a great pasta dish.

Ingredients and their roles in the recipe

For The Old Spaghetti Factory Clam Sauce recipe, you’ll need:

Unsalted butter – helps the veggies saute without burning and cooks the AP flour into a roux to thicken the sauce.
Garlic, minced – brings the aromatic punch to cut through the richness of the sauce.
White onion, small diced – sweetens the sauce without overpowering it as white sugar would.
Celery, small diced – adds vegetal notes and a bit of freshness to prevent the sauce from feeling too heavy.
All-purpose flour – forms a roux with butter to thicken the sauce.
Chopped clams, canned – the star of the show with their briny, sea flavor and slight chew.
Half-and-half – gives the sauce a creamy base without being as rich as heavy cream.
Ground thyme – adds a bit of earthy notes to help balance out the heaviness of some of the other ingredients.
Salt – enhances the taste of all the other ingredients in the recipe.
Linguine pasta, cooked according to package directions – the bulk of the dish. Linguine is the traditional pasta pairing with clams, but you can use your favorite type of pasta.
Parsley, finely chopped – provides a boost of color and some freshness as a garnish.

Clams, garlic, butter, onion, celery, flour, cream, linguine, and pepper.

How to make white clam sauce like the Old Spaghetti Factory

Add the unsalted butter to a large skillet over medium-low heat.
Swirl the butter around the skillet, then add the minced garlic, diced onions, and diced celery.
Stir the vegetables, then cook until tender. Stir often to prevent browning.
Sprinkle the all-purpose flour into the skillet and stir until it incorporates into the butter. Stir occasionally until you cook out the rawness of the flour, about two to three minutes.
Turn off the heat.
Drain the cans of clams into a clean saucepan, and reserve the clams for later. Add the half-and-half, ground thyme, and salt. Stir to combine.
Heat the clam juice mixture to just below a simmer.
Turn the heat back to medium-low under the vegetables, then carefully pour the hot clam juice mixture into the skillet while stirring to avoid lumps.
Continue to stir over medium-low heat until the sauce thickens.
Add the reserved clams.
Serve over the cooked linguine and garnish with the chopped parsley.

Storing White Clam Sauce and reheating instructions

Refrigerator storage: Quickly cool the sauce to room temperature by pouring it into a large, shallow container. Transfer the cooled sauce to an airtight container and refrigerate for up to three days. If possible, store the Old Spaghetti Factory Clam Sauce recipe separately, since sauced pasta needs to be eaten the next day.

Freezer storage: Due to the half-and-half, it is not recommended to freeze leftover Old Spaghetti Factory White Clam Sauce.

Reheating instructions: Warm the sauce in a pan slowly over low heat. Stir often to prevent the sauce from simmering. If the sauce is a little thick, add a splash of half-and-half or milk to help loosen it.
