2 pounds littleneck clams β soaked 20β30 minutes in cold water, then scrubbed
2 tbsp kosher salt β for pasta water
12 ounces linguine β dry
0.25 cup extra-virgin olive oil
6 cloves garlic β thinly sliced
0.5 tsp red pepper flakes
0.5 cup dry white wine
1 cup bottled clam juice
1 medium lemon β zested and juiced (use 1 tsp zest and 1 tbsp juice)
2 tbsp unsalted butter
0.25 cup flat-leaf parsley β finely chopped
Instructions
Place the littleneck clams in a large bowl of cold water and let soak 20β30 minutes to purge sand, then scrub each under cold running water.
Bring a large pot (4β5 quarts) of water to a boil; add the kosher salt.
Warm the olive oil in a wide, deep skillet over medium heat.
Add the garlic and red pepper flakes; cook, stirring, until fragrant but not browned, 1β2 minutes.
Pour in the white wine and simmer until reduced by about half, 2β3 minutes.
Add the bottled clam juice and bring to a lively simmer.
Add the clams to the skillet in a single layer; cover and cook, shaking the pan occasionally, until most clams have opened, 5β7 minutes. Transfer opened clams to a bowl as they open; discard any that remain closed after cooking.
Drop the linguine into the boiling water and cook until 1β2 minutes shy of al dente, per package time.
While the pasta cooks, finely grate the lemon zest and squeeze the juice; measure 1 tsp zest and 1 tbsp juice. Roughly chop half of the cooked clams and return the chopped clam meat to the skillet; keep the remaining clams in their shells for serving.
Ladle about 0.5 cup of the pasta cooking water into the skillet and bring the sauce to a brisk simmer.
Using tongs, transfer the linguine to the skillet; toss vigorously over medium-high heat until the sauce emulsifies and lightly coats the pasta, 1β2 minutes. Off the heat, add the butter, parsley, the reserved lemon zest, and 1 tbsp lemon juice; toss until glossy.
Add the remaining whole clams to the pan, toss to warm through, and adjust seasoning if needed. Serve immediately, dividing clams evenly and spooning any sauce over each portion.
