Transfer the baking dish to the preheated oven and bake for 8–10 minutes, or until the shrimp are just opaque and curled into loose C-shapes. They should be pink with no gray translucence remaining, but still tender. Avoid overbaking, as shrimp can turn rubbery quickly.
Remove the dish from the oven and immediately sprinkle the chopped parsley over the shrimp. Give everything a gentle stir to coat the shrimp in the lemon butter and herbs, then taste the sauce and adjust seasoning with a pinch more salt or a squeeze of lemon if needed.
Serve the shrimp hot, spooning the lemon butter sauce over each portion. Offer lemon wedges at the table and any sides you’ve prepared to catch the extra sauce.
