Using kitchen shears, cut down the top of each lobster tail shell, stopping before the tail fin. Gently spread the shell open to expose the meat.
Carefully lift the lobster meat out of the shell and lay it on top of the shell. This is called 'butterflying'. You can keep the meat attached at the base.
In a small bowl, melt the butter. Stir in the minced garlic, chopped parsley, lemon zest, salt, and pepper.
2 each Lobster Tails
Brush the exposed lobster meat generously with the garlic butter mixture.
Place the lobster tails on the preheated grill, shell-side down. Grill for 5-7 minutes, or until the meat is opaque and cooked through. The shell will turn bright red.
If desired, brush with additional garlic butter before serving.
Serve immediately.
Notes
For a spicier kick, add a pinch of red pepper flakes to the garlic butter. Serve with lemon wedges for extra zest.
