Ingredients You’ll Need

A large piece of raw white fish fillet lies on a white plate beside a small bunch of fresh green thyme. Surrounding the plate on a white marbled surface are four small glass bowls: one filled with melted yellow butter, another with thin lemon slices showing bright yellow edges and a pale yellow center, a third containing finely chopped shallots and a small piece of minced garlic, and the last holding a mix of coarse salt and ground black pepper. The colors are soft and natural, with the fish showing light pinkish-white flesh and the herbs and other ingredients adding fresh green, yellow, and light purple hues.

The beauty of this recipe is how a handful of simple, quality ingredients come together to create a symphony of flavor and texture. Each component plays an essential role in bringing out the fresh essence of the cod while layering in vibrant aromas and juicy brightness.

Fresh thyme (12 sprigs): Adds a woody, herbal note that infuses the fish with subtle complexity.
Cod fillets (1 pound): The star of the dish, delivering flaky, mild seafood that’s wonderfully tender when grilled.
Kosher salt (1/2 teaspoon): Enhances the natural flavor of the fish without overpowering it.
Ground black pepper (1/4 teaspoon): Offers a gentle kick and depth to balance the butter and citrus.
Melted butter (2 tablespoons): Provides richness and helps carry the garlic and shallot flavors evenly across the fillets.
Finely diced shallot (2 tablespoons): Introduces a mild sweetness and delicate sharpness.
Minced garlic (2 cloves): Adds a savory punch that complements the fish beautifully.
Lemon (1, thinly sliced): Brings a bright, zesty lift that contrasts perfectly with the buttery glaze.
Optional fresh herbs (chopped parsley, tarragon, or thyme): For garnish and an extra pop of color and fragrance on serving.

How to Make Grilled Cod in Foil Recipe

A raw fish fillet is laid flat on a sheet of shiny silver foil, with small green herb sprigs underneath it peeking out slightly. The fillet is pale pinkish-white in color with a moist texture. The surface of the fish is covered with a layer of finely chopped light yellow and light brown ingredients, including small bits of garlic and shallot, all spread evenly. The whole scene rests on a white marbled texture background. photo taken with an iphone --ar 4:5 --v 7

Step 1: Prepare the Grill and Foil Packets

Start by heating your grill to medium-high heat, aiming for about 365 degrees Fahrenheit. While it warms, tear off squares of heavy-duty aluminum foil large enough to wrap around each fillet separately. This setup ensures each piece cooks evenly and locks in its juices.

Step 2: Season the Cod

Place each cod fillet on its own piece of foil. Sprinkle kosher salt and ground black pepper directly onto the fish to enhance its natural flavor profile without masking its delicate character.

Step 3: Make the Flavorful Butter Mixture

In a small bowl, whisk together melted butter, diced shallot, and minced garlic. This combination not only enriches the fish but also infuses it with layers of aromatic sweetness and savory depth. Brush this mixture generously over each fillet, ensuring every bite will be rich and compelling.

Step 4: Add Lemon Slices and Fresh Herbs

Lay several thin lemon slices atop each cod fillet, creating a bright citrus layer that steams into the fish during grilling. If you like, tuck in a couple of fresh thyme sprigs under or on the lemon for an even more fragrant experience.

Step 5: Seal the Foil Packets

Fold and crimp the edges of the foil squares around each fillet to make sealed packets. This method traps steam and locks in moisture, resulting in perfectly tender fish that flakes apart with ease once cooked.

Step 6: Grill the Packets Gently

Reduce the grill heat to medium and place the foil packets on the grill away from direct flames. Indirect heat is key here to avoid burning and to allow the cod to cook evenly for about 8 to 10 minutes. The fish is done when it flakes effortlessly and reaches an internal temperature of 145 degrees Fahrenheit.

Step 7: Serve and Garnish

Carefully remove the packets from the grill and open them to reveal steamy, beautifully cooked cod. Transfer the fillets to plates and sprinkle with additional chopped fresh herbs if desired. Serve immediately for the best flavor and texture.

Garnishes

Fresh herbs such as parsley, tarragon, or extra thyme are perfect for sprinkling over the top just before serving. They add a vibrant burst of color and enhance the herbal notes already present in the dish, making every forkful even more delightful.

Side Dishes

This Grilled Cod in Foil Recipe pairs wonderfully with simple sides that complement rather than overpower the fish. Think light options like a crisp green salad with a lemon vinaigrette, steamed asparagus, or fluffy couscous tossed with fresh herbs. Even buttery roasted potatoes or grilled vegetables would be lovely for a heartier meal.

Creative Ways to Present

For a casual dinner, serve the cod straight from the foil packets at the table, letting everyone unwrap their own packet to enjoy the steam and aroma. Alternatively, present the fillets artistically on white plates with a wedge of lemon and a sprinkle of fresh herbs to elevate the experience.

Make Ahead and Storage

Storing Leftovers

If you have any leftover grilled cod, place the fillets in an airtight container and refrigerate for up to two days. Keep the lemon slices and herbs with the fish to help maintain moisture and flavor during storage.

Freezing

While best fresh, you can freeze cooked cod in foil packets for up to one month. Wrap each packet tightly in plastic wrap before placing it into a freezer bag to prevent freezer burn and keep the flavors locked in.

Reheating

Reheat gently by steaming the foil packets in a warm oven (about 275 degrees Fahrenheit) for 10 to 15 minutes or until warmed through. Avoid microwave reheating as it can dry out the delicate fish and alter the texture.

FAQs

Can I use frozen cod for this Grilled Cod in Foil Recipe?

Yes, frozen cod fillets will work fine, but make sure to thaw them completely before grilling to ensure even cooking and prevent excess moisture from affecting the foil packets.

What if I don’t have a grill? Can I make this recipe indoors?

You can bake the foil packets in a preheated oven at 400 degrees Fahrenheit for about 12 to 15 minutes. The foil trapping the steam will still tenderize the fish beautifully.

Can I swap out the butter for olive oil?

Absolutely! Olive oil is a great alternative that still brings rich flavor and helps carry the garlic and shallot notes. It’s also a nice option for a lighter, dairy-free version.

How do I know when the cod is perfectly cooked?

The fish should flake easily with a fork and reach an internal temperature of 145 degrees Fahrenheit. Overcooking will make it dry, so aim for just tender and flaky.

Can I add other vegetables in the foil packets?

Yes, thinly sliced vegetables like zucchini, bell peppers, or cherry tomatoes can be included for a complete grilled meal. Just be mindful of cooking times to keep everything tender but not mushy.
