Bring a large pot of salted water to a boil and cook the linguine according to package directions until al dente, reserving 2 tablespoons of the pasta water before draining.
While the pasta cooks, pat the shrimp dry with paper towels and season them evenly with sea salt and black pepper.
In a large skillet over medium heat, melt the grass-fed butter until it starts to shimmer.
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, cooking for 2 minutes per side until they are pink and opaque.
Pour in the white wine and lemon juice, using a wooden spoon to scrape up any browned bits from the bottom of the pan.
Add the cooked linguine and the reserved pasta water to the skillet, tossing thoroughly to coat the noodles in the glossy garlic-butter sauce.
Remove from the heat, garnish with freshly chopped parsley, and serve immediately.
