Step 1

First, cook the linguine in a large pot of boiling salted water until al dente.

Step 2

While the pasta is cooking, heat a large skillet over medium heat with the olive oil.

Step 3

Add the garlic and crushed red pepper flakes and cook for 1-2 minutes until lightly browned.

Step 4

Deglaze the pan with the white wine and add the clams and mussels. Cover and cook for 3-5 minutes until all of the shells open.

Step 5

Add the shrimp, re-cover the pan, and cook for 2-3 minutes until they are mostly pink and opaque.

Step 6

Add the calamari and scallops, re-cover, and cook for another 2 minutes.

Step 7

Add the Italian gravy or marinara along with a bit of the pasta cooking liquid and let the sauce simmer for 2-3 minutes to heat through. Discard any mussels or clams whose shells did not open.

Step 8

While the sauce is simmering, drain the cooked linguine from the remaining liquid.

Step 9

Toss the pasta with the seafood sauce and serve immediately, garnished with parsley if desired.
