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 olive oil and ghee in a large skillet over medium heat.
Add the minced garlic and red pepper flakes to the skillet, sautéing for 1 minute until fragrant but not browned.
Increase the heat slightly and add the shrimp, seasoning with sea salt and black pepper.
Cook the shrimp for 2-3 minutes per side until they are pink, opaque, and perfectly tender.
Drain the pasta, reserving a splash of pasta water, and add the noodles directly into the skillet with the shrimp.
Stir in the lemon juice, lemon zest, and fresh parsley, tossing well to coat every strand of pasta in the silky sauce.
Serve immediately, adding a spoonful of reserved pasta water if needed to loosen the sauce.
