Linguine with White Clam Sauce is a classy and sophisticated Italian-American pasta dish, flavored by a white wine and clam sauce, soft linguine, baby clams, and topped with fresh parsley and Parmesan cheese.
In a 5 to 6 quart pan over high heat, bring about 4 quarts water to a boil. Add about 1 Tablespoons Kosher salt to the water. Add linguine and cook, stirring occasionally, until molto al dente (barley tender to bite, about 10 minutes. Ladle out 1/2 cup pasta water in case you need to thin the sauce.
Whisk the 2 Tablespoon cornstarch into the 1/4 cup clam juice and set aside.
Meanwhile in a 10 to 12-inch large skillet over medium-high heat, sauté onion in the olive oil and butter until tender. Add the garlic and red pepper flakes and cook until fragrant but do not brown. About 1 to 2 minutes.
Add the white wine or broth, 3/4 cup clam juice, and reserved liquid from clams and bring to a boil.
Boil for about 2 minutes and then stir in the cornstarch clam juice slurry until the sauce thickens.
Add clams and stir occasionally until hot, 1 to 2 minutes.
Drain the linguine. Add to the clam sauce along with the parsley.
Sprinkle with freshly ground black pepper. Mix.
Serve with an additional sprinkle of parsley and Parmesan cheese.
If you’d like a thinner sauce - add a Tablespoon or two of pasta water.
