Bring a large pot of salted water to a boil and cook the linguine according to package directions until al dente.
While the pasta cooks, heat the extra virgin olive oil and ghee in a large skillet over medium heat until shimmering.
Add the minced garlic and red pepper flakes to the skillet, sautéing for about 1 minute until the aroma is fragrant and golden.
Increase the heat to medium-high and add the shrimp to the skillet in a single layer, seasoning with sea salt and black pepper.
Cook the shrimp for 2-3 minutes per side until they are pink and opaque, being careful not to overcook them.
Reserve 0.25 cup of the starchy pasta water, then drain the linguine and add it directly into the skillet with the shrimp.
Stir in the lemon juice, lemon zest, and fresh parsley, adding a splash of the reserved pasta water to create a light, silky sauce.
Toss everything together until the noodles are well-coated and the flavors are combined, then serve immediately in a warm bowl.
