Ingredients
Seafood and Vegetables
- 4 fillets cod (or other white fish such as halibut or flounder), as large as possible
- 30 raw medium shrimp, peeled, deveined, tail on, patted dry
- 4 ears corn, husked and halved
- 24 ounces baby red potatoes
- 2 medium lemons, sliced (12 slices total)
Butter Sauce
- 1 cup unsalted butter
- 3 tablespoons finely chopped fresh dill
- 2 tablespoons minced fresh garlic
- 1/4 teaspoon salt (or to taste)
- 1 pinch black pepper (to taste)
Instructions
- Preheat and Prepare Foil: Preheat your oven to 350°F. Tear 8 pieces of aluminum foil, each about 2-3 feet long, and stack them into 4 groups of 2. This creates double-layered foil sheets that ensure no juices escape during baking. Lightly spray the top layer of each double sheet with cooking spray to prevent sticking.
- Make the Butter Sauce: In a microwave-safe bowl, melt the unsalted butter for about one minute until fully liquid. Stir in the finely chopped fresh dill, minced garlic, salt, and black pepper until well combined. Set this aromatic butter mixture aside for assembly.
- Assemble Foil Packets: On each prepared foil sheet, lay a cod fillet lengthwise in the center. Arrange 6 of the shrimp evenly on top of the fish. Add two halves of corn and about 1/2 to 3/4 cup of baby red potatoes around the fish and shrimp. Drizzle roughly one-quarter of the dill butter sauce over the seafood and vegetables, focusing especially on the shrimp to enhance flavor. Finally, place 2-3 lemon slices on top. Fold the foil around the ingredients, pinching the edges firmly to seal the packet completely. If needed, wrap an additional piece of foil around each packet. Place the packets, seam side up, on a large baking sheet. Repeat this for all four packets.
- Bake the Packets: Place the baking sheet in the preheated oven and bake for 25-30 minutes if the fish fillets are 8 ounces or smaller, or 30-40 minutes if the fillets are larger. The packets are done when the corn, butter, and garlic aromas are fragrant through the foil, and the seafood and vegetables are cooked through.
- Serve: Carefully open the hot foil packets (watch out for steam) and serve directly in the foil for a fuss-free presentation. Enjoy the seafood boil with your choice of sides or simply on its own.
Notes
- Be cautious when opening foil packets as steam can be very hot.
- Adjust salt to taste based on the natural seasoning of the seafood.
- For a spicier version, add a pinch of red pepper flakes to the butter sauce.
- If you don’t have fresh dill, dried dill can be substituted but use about 1 tablespoon.
- Make sure to evenly distribute ingredients in each packet to ensure even cooking.
- Double layering of foil helps prevent leaks and keeps the packets intact during baking.
