Bring a pot of salted water to a boil and cook the pasta until al dente according to package instructions.
While the pasta cooks, heat the ghee in a large skillet over medium-high heat.
Add the trimmed asparagus pieces to the skillet and sauté for 3 minutes until they are vibrant green and slightly tender.
Add the shrimp, minced garlic, sea salt, black pepper, and red pepper flakes to the pan.
Cook the shrimp for approximately 2 minutes per side until they are pink, opaque, and cooked through.
Drain the pasta and add it directly to the skillet with the shrimp and asparagus.
Toss in the lemon juice, lemon zest, and chopped parsley, stirring until the pasta is well coated in the garlic butter sauce.
Serve immediately while the dish is hot and fragrant.
