Bring a 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 them with sea salt and black pepper.
Heat the extra virgin olive oil and ghee in a large skillet over medium-high heat until the ghee is melted and shimmering.
Add the shrimp to the skillet in a single layer and sear for 1-2 minutes per side until pink and opaque, then remove shrimp from the pan and set aside.
In the same skillet, add the minced garlic and red pepper flakes, sautéing for 30 seconds until fragrant but not browned.
Pour in the vegetable broth to deglaze the pan, scraping up any browned bits, and simmer for 1 minute.
Stir in the lemon juice and lemon zest, then return the shrimp to the skillet along with the cooked linguine.
Toss everything together to coat the pasta in the sauce, garnish with fresh parsley, and serve immediately.
