Bring a pot of salted water to a boil and cook the linguine according to package directions until al dente.
While the pasta cooks, spiralize the zucchini into thin ribbons and pat the prawns dry with a paper towel.
Season the prawns with sea salt and black pepper on both sides.
Heat the ghee in a large skillet over medium-high heat until shimmering.
Add the prawns to the skillet in a single layer and sear for 2 minutes per side until pink and opaque, then remove and set aside.
In the same skillet, add the minced garlic and red pepper flakes, sautéing for 30 seconds until aromatic.
Deglaze the pan with the white wine and lemon juice, scraping up any flavorful browned bits from the bottom.
Add the zucchini ribbons to the skillet and toss for 1 minute until just slightly softened.
Return the prawns to the pan along with the cooked linguine and a small splash of the pasta cooking water.
Toss everything together until the sauce coats the noodles and prawns evenly, then garnish with fresh parsley and serve immediately.
