In a small bowl, combine bread crumbs, cheese, shallot, garlic, zest, parsley, thyme, oregano, salt, and pepper. Add butter and Cognac; using fingers, massage butter into mixture to form a paste. Top oysters with butter mixture.
Broil until lightly browned on top, about 5 minutes. Sprinkle with lemon juice. Serve with toasted bread. Garnish with thyme, if desired.
Notes
Note: Butter mixture can be made ahead and refrigerated. Bring to room temperature before topping oysters.
