Build the fire in your oven to approximately 450 degrees.
Boil water and start linguine cooking on the stove, per package instructions.
Clean shrimp; rinse and remove the vein, if necessary; pat dry.
Place shrimp in an ovenproof or terracotta pan in a single layer.
Scatter butter pieces, garlic, breadcrumbs, parmesan, and parsley over the top. Reserve some butter to melt in a seperate container on the hearth for use on the linguine (optional).
Pour 1/2 of the lemon juice over the top of the shrimp.
Place in your oven on the opposite side from the flame -- keep a close eye! This dish cooks quickly.
Bake until shrimp begins to turn pink and breadcrumbs begin to turn brown -- approximately 2 minutes.
Remove pan from the oven; mix and turn over the shrimp; add remaining lemon juice.
Return the pan to the oven and bake approximately 2 minutes more, until the shrimp is pink throughout.
This dish may be served over linguine. Add melted butter and grated Parmesan to the pasta, if desired.
