Ingredients

Fish and Seasoning

  • 1 pound cod fillets
  • 1/2 teaspoon kosher salt
  • 1/4 teaspoon ground black pepper
  • 12 sprigs of fresh thyme

Butter Mixture

  • 2 tablespoons butter (melted)
  • 2 tablespoons finely diced shallot
  • 2 cloves garlic (finely minced)

Additional Ingredients

  • 1 lemon (thinly sliced)
  • optional – additional chopped fresh herbs for serving (like parsley, tarragon, or thyme)

Instructions

  1. Preheat the Grill: Heat your grill to medium-high heat, approximately 365 degrees Fahrenheit, to create the ideal cooking environment for the cod fillets.
  2. Prepare Foil Packets: Tear off several large squares of aluminum foil, one for each cod fillet. Place each fillet on a foil square and season generously with kosher salt and ground black pepper.
  3. Make Butter Mixture: In a small bowl, combine the melted butter, finely diced shallot, and minced garlic. Brush this aromatic mixture evenly over each seasoned cod fillet to impart rich flavor.
  4. Add Lemon Slices: Lay several thin slices of lemon on top of each butter-coated cod fillet to add a fresh, citrusy brightness to the dish.
  5. Seal the Foil Packets: Carefully fold and crimp the edges of the foil squares to create sealed packets around each fillet, ensuring that no steam escapes during cooking.
  6. Grill the Cod: Reduce the grill heat to medium and place the foil packets on the grill grates, avoiding direct flames to utilize indirect heat. Grill for 8 to 10 minutes, or until the fish flakes easily and reaches an internal temperature of 145 degrees Fahrenheit when checked with an instant-read thermometer.
  7. Serve: Remove the foil packets from the grill, unwrap carefully, and transfer the cooked cod to serving plates. Garnish with additional fresh herbs like parsley, tarragon, or thyme if desired, and serve immediately for best flavor and texture.

Notes

  • Use fresh, firm cod fillets for the best texture and flavor.
  • Be careful when opening the hot foil packets to avoid steam burns.
  • Indirect grilling is key to prevent burning and ensure even cooking.
  • Internal temperature of 145°F guarantees safe and perfectly cooked fish.
  • Optional fresh herbs add extra flavor and a pop of color.
  • Foil packets can be prepared ahead for an easy grilling session.
