Prepare the basmati rice according to package instructions until fluffy and set aside.
Preheat your oven to 400°F and toss the asparagus with the olive oil, a pinch of sea salt, and black pepper.
Roast the asparagus on a parchment-lined baking sheet for 8-10 minutes until crisp-tender.
Pat the prawns dry with a paper towel and season them lightly with sea salt and black pepper.
Heat a large skillet over medium heat and melt the ghee until shimmering.
Add the minced garlic to the skillet and sauté for 30 seconds until fragrant but not browned.
Increase the heat to medium-high, add the prawns to the skillet, and cook for 2 minutes per side until pink and opaque.
Remove the skillet from the heat and stir in the fresh parsley and half of the lemon juice.
Fluff the warm rice with a fork and fold in the remaining lemon juice and the lemon zest.
Plate the lemon rice with the roasted asparagus and top with the garlic butter prawns, drizzling any remaining sauce from the pan over the dish.
