Step 1

Drizzle some oil in a large pot of boiling salted water, add 1 tablespoon of salt and the linguine, and cook for 7 to 10 minutes, or according to the directions on the package.

Step 2

Meanwhile, in another large (12-inch), heavy-bottomed pan, melt the butter and olive oil over medium-low heat. Add the garlic. Saute for 1 minute. Be careful, the garlic burns easily! Add the shrimp, 1 1/2 teaspoons of salt, and the pepper and saute until the shrimp have just turned pink, about 5 minutes, stirring often. Remove from the heat, add the parsley, lemon zest, lemon juice, lemon slices, and red pepper flakes. Toss to combine.

Step 3

When the pasta is done, drain the cooked linguine and then put it back in the pot. Immediately add the shrimp and sauce, toss well, and serve.
