- Heat oil and garlic in an 8" skillet over medium. Cook until garlic is golden, 4–6 minutes. Stir in minced herbs and pepper; let cool. Heat oven broiler. Line a baking sheet with rock salt about ¼" deep. Nestle oysters onto bed of rock salt. Spoon reserved garlic oil over oysters and sprinkle with feta, crabmeat, and capers. Broil until feta is golden brown and the oysters begin curling at the edges, 2–4 minutes. Garnish with parsley and scallions; serve with hot sauce, lemon wedges, and toasted ciabatta, if you like.
