Louisiana BBQ Shrimp

1 – 2 lbs. large shrimp
8 tablespoons butter, melted
3 tablespoons Worcestershire
1/4 teaspoon cayenne
1/2 teaspoon coarse salt
1/4 teaspoon fresh ground pepper
2 teaspoons fresh thyme (or 1/2 teaspoon dried)
1 tablespoon chopped fresh rosemary
1 tablespoon olive oil

Dehead shrimp if necessary, but don't peel. Place in a shallow dish (I use a pie pan). Mix remaining ingredients together and pour over shrimp. Cover and place in the refrigerator to marinate for 2-3 hours.

Bake in 350 degree oven uncovered for 15-20 minutes. Serve with French bread to sop up all the wonderful juice.

NOTES: Sometimes I add whole mushrooms.
