Bring a large pot of salted water to a boil and cook the whole grain linguine according to package instructions until al dente.
While the pasta cooks, pat the shrimp dry with paper towels and season evenly with sea salt and black pepper.
In a large skillet over medium heat, combine the ghee and extra virgin olive oil until the ghee is fully melted and shimmering.
Add the minced garlic and red pepper flakes to the skillet, sautéing for 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.
Squeeze in the fresh lemon juice and add the chopped parsley, stirring to combine with the shrimp and garlic butter.
Drain the linguine, reserving a small amount of pasta water, and add the noodles directly to the skillet.
Toss everything together for 1 minute, adding a splash of the reserved pasta water if needed to create a glossy sauce that coats the noodles.
Divide the scampi into bowls and serve immediately while hot.
