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, pat the shrimp dry with paper towels and season them with sea salt and black pepper.
In a large skillet over medium heat, add the olive oil and ghee until melted and shimmering.
Add the minced garlic and red pepper flakes to the skillet, sautéing for about 1 minute until the garlic is fragrant but not browned.
Increase the heat to medium-high and add the shrimp in a single layer, cooking for 2 minutes per side until they turn pink and opaque.
Stir in the lemon juice and lemon zest, scraping up any flavorful bits from the bottom of the pan.
Reserve 2 tablespoons of the pasta cooking water, then drain the linguine and add it directly to the skillet with the shrimp.
Toss everything together with the fresh parsley and the reserved pasta water to create a light, silky sauce.
Serve immediately in a warm bowl, ensuring the garlic-lemon sauce is evenly distributed over the pasta.
