Bring a large pot of salted water to a boil and cook the linguine according to package directions until al dente.
Reserve 2 tablespoons of the pasta cooking water, then drain the noodles and set aside.
Heat the extra virgin olive oil in a large skillet over medium heat.
Add the minced garlic and red pepper flakes to the skillet, sautéing for about 1 minute until fragrant but not browned.
Increase the heat to medium-high and add the shrimp in a single layer, seasoning with sea salt and black pepper.
Cook the shrimp for 2 minutes per side until they are pink, opaque, and cooked through.
Stir in the lemon juice, lemon zest, and the reserved pasta water to create a light sauce.
Add the cooked linguine and chopped fresh parsley to the skillet, tossing everything together until the pasta is well coated.
Serve immediately in a shallow bowl, garnished with extra parsley if desired.
