Bring a large pot of salted water to a boil and cook the whole wheat pasta until al dente according to package instructions.
While the pasta cooks, peel and devein the shrimp, mince the garlic cloves, and finely chop the fresh parsley.
Heat the ghee in a large skillet over medium heat until it is melted and shimmering.
Add the shrimp to the skillet in a single layer and season with sea salt, black pepper, and red pepper flakes.
Sauté the shrimp for 2 minutes per side until they are pink and opaque, then add the minced garlic and cook for 1 additional minute until fragrant.
Drain the pasta, reserving approximately 2 tablespoons of the starchy cooking water.
Add the cooked pasta and reserved water to the skillet, tossing everything with the lemon juice and fresh parsley until the noodles are glossy and well-coated.
