Food safety
Grill cobia to 145°F or until opaque and it flakes easily with a fork. Keep the herb butter refrigerated until serving and use a clean platter for the cooked fish. Scrub lemons before zesting and rinse herbs under running water.
Allergens: fish, milk
Equipment
- outdoor grill or grill pan
- wide metal spatula
- small mixing bowl
- knife
- cutting board
- instant-read thermometer
Ingredients (for 4 servings)
- 1.5 pounds cobia fillets, about 1 inch thick
- 1 tablespoon olive oil
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 4 tablespoons butter, softened
- 2 tablespoons fresh parsley, finely chopped
- 1 tablespoon fresh chives or green onion tops, finely chopped
- 1 garlic clove, minced
- 1 teaspoon lemon zest
- 1 lemon, cut into wedges
Directions
1. Scrub the lemons under running water before zesting and cutting. Rinse the herbs and chop finely.
2. Mash the softened butter with the parsley, chives, garlic, lemon zest, and a pinch of the salt. Cover and refrigerate until serving.
3. Heat the grill to medium-high, clean the grates, and oil them well.
4. On a board used only for raw fish, pat the cobia dry. Rub with the oil and season with the remaining salt and the black pepper.
5. Grill the fish 4 to 5 minutes without moving it, then flip with a wide spatula and grill 4 to 5 minutes more.
6. The fish is done when it is opaque and flakes easily with a fork, or reaches 145°F in the thickest part.
7. Move to a clean platter, top each fillet with a spoonful of herb butter, and serve with lemon wedges.
8. Chill leftovers and any remaining herb butter within 2 hours (1 hour if the room is above 90°F).
