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, pat the shrimp dry with paper towels and season with the sea salt and black pepper.
Heat the ghee in a large skillet over medium heat until shimmering.
Add the minced garlic and red pepper flakes to the skillet, sautéing for about 1 minute until the garlic is aromatic and golden.
Increase the heat to medium-high and add the shrimp in a single layer, cooking for 2 minutes per side until pink and opaque.
Pour in the vegetable broth and lemon juice to deglaze the pan, scraping up any flavorful bits from the bottom.
Drain the linguine, reserving a splash of pasta water, and add the noodles directly to the skillet.
Toss everything together for 1 minute to coat the pasta in the silky sauce, adding a bit of pasta water if needed to reach desired consistency.
Remove from heat and garnish with freshly chopped parsley before serving.
