Bring a large pot of salted water to a boil and cook the whole wheat linguine according to package directions until al dente.
While the pasta cooks, pat the shrimp dry with paper towels and season them lightly with sea salt and black pepper.
In a large skillet over medium heat, melt the ghee with the olive oil.
Add the minced garlic and red pepper flakes to the skillet, sautéing for about 1 minute until the garlic is fragrant but not browned.
Add the shrimp to the skillet in a single layer and cook for 2 minutes per side until pink and opaque.
Stir in the fresh lemon juice and lemon zest, scraping up any flavorful bits from the bottom of the pan.
Drain the linguine, reserving a splash of pasta water, and add the noodles directly into the skillet with the shrimp.
Toss everything together until the pasta is coated in the garlic sauce, adding a bit of reserved water if needed for moisture.
Remove from heat, garnish with freshly chopped parsley, and serve immediately.
