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, peel and devein the shrimp, then pat them completely dry with a paper towel to ensure a good sear.
In a large skillet over medium heat, melt the ghee and combine it with the extra virgin 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.
Increase the heat to medium-high and add the shrimp in a single layer, seasoning with sea salt and black pepper.
Cook the shrimp for 2 minutes per side until they turn pink and opaque, then remove them from the pan and set aside.
Pour the vegetable broth and lemon juice into the same skillet, scraping up any browned bits from the bottom of the pan.
Simmer the sauce for 2 minutes to reduce slightly, then return the shrimp and cooked linguine to the pan.
Toss everything together until the pasta is coated in the sauce, then garnish with fresh chopped parsley before serving.
