Grilled Cod Wrapped in Zucchini with Tomato Bacon Sauce on the Grill

Mastering Grilled Cod Wrapped in Zucchini with Tomato Bacon Sauce

Wrapping cod in thin zucchini slices protects the delicate fish from falling apart on the grill while keeping the flesh moist during the high-heat cooking process. This recipe yields 4 servings, requires 20 minutes of preparation time, and takes 25 minutes of total cook time.

When I developed this dish for the grill, I noticed the zucchini ribbons act like a natural steamer around the fish; cooking the bundles about 18 inches from the center wood fire on the flat-top renders the zucchini perfectly tender with a slight char, while the cod hits exactly 135°F internally without losing a drop of moisture. Serving it over a smoky, bacon-infused tomato sauce creates an incredible contrast of light fish and rich, savory pan juices.

Ingredients

Selecting firm, 1-inch-thick fish fillets and slicing the zucchini no thicker than 1/8-inch ensures the vegetable wrap cooks quickly and evenly without leaving the center raw.

The Fish and Wrap

• 4 (6-ounce) skinless cod fillets
• 2 medium zucchini, sliced lengthwise 1/8-inch thick
• 2 tablespoons olive oil
• 1 teaspoon kosher salt
• 1/2 teaspoon freshly ground black pepper

The Tomato Bacon Sauce

• 6 slices thick-cut bacon, diced
• 1 cup diced yellow onion
• 3 cloves garlic, minced
• 1 (14.5-ounce) can fire-roasted diced tomatoes
• 1/2 cup chicken broth
• 1 tablespoon fresh thyme leaves

Instructions

Executing this dish requires building a robust, simmering pan sauce while simultaneously searing the vegetable-wrapped fish on the flat-top.

1. Prepare the Zucchini Wrapped Cod

1. Pat the cod fillets completely dry with paper towels and season evenly with the kosher salt and black pepper.
2. Lay 3 to 4 thin slices of zucchini slightly overlapping on a cutting board, place one cod fillet in the center, and wrap the zucchini ends over the top to enclose the fish.
3. Secure the wrapped bundles with a toothpick, then brush the exterior of the zucchini lightly with the olive oil.

2. Fire Up the Grill

1. Build a wood or charcoal fire in the center of the Arteflame to bring the 1,000°F center grate to searing temperatures and heat the outer flat-top ring.
2. Lightly oil the carbon steel flat-top cooking surface.
3. For conventional gas grills, preheat one side to high for searing and leave the other side on medium-low for the skillet.

3. Build the Tomato Bacon Sauce

1. Place a cast-iron skillet on the outer flat-top ring where the temperature rests around 350°F, and add the diced bacon.
2. Cook the bacon for 8 to 10 minutes until the fat renders and the meat crisps, then stir in the diced yellow onion and cook for an additional 4 minutes until translucent.
3. Stir in the minced garlic for 60 seconds, then pour in the fire-roasted tomatoes, chicken broth, and fresh thyme leaves.
4. Slide the skillet further out to the coolest edge of the flat-top to gently simmer and reduce while you cook the fish.

4. Grill the Zucchini Wrapped Fish

1. Place the zucchini-wrapped cod directly on the flat-top, positioning them halfway between the 1,000°F center grate and the outer edge (aiming for a 400°F to 450°F zone).
2. Sear for 4 to 5 minutes per side, turning carefully with a wide metal spatula, until the zucchini is blistered and the internal temperature of the cod reaches 135°F on a digital meat thermometer.
3. Remove the cod from the grill, spoon the warm tomato bacon sauce onto four plates, and set one wrapped fillet atop the sauce on each plate before serving.

Pro Tips for Grilling Wrapped Fish

Proper wrapping technique and precise heat management prevent the vegetable ribbons from unraveling and the fish from drying out over the open fire.

• Trying to cook a simmering bacon sauce and delicate fish simultaneously on a conventional grill often means juggling a side burner and a stick-prone grate, risking burnt sauce or mangled fillets. The Arteflame solves this structurally by letting you simmer the skillet on the cooler outer flat-top ring while searing the fish closer to the 1,000°F center grate, all on one continuous surface.
• Use a mandoline slicer set to exactly 1/8-inch thickness to ensure the zucchini is pliable enough to bend around the cod without snapping.
• If the zucchini slices feel too stiff to wrap, salt them lightly and let them sit on a cutting board for 10 minutes to draw out moisture and increase flexibility before wrapping the fish.
• Insert toothpicks at a 45-degree angle through the overlapping zucchini ends directly into the thickest part of the cod to anchor the wrap securely.

Recipe Variations and Ingredient Swaps

Modifying the wrapper vegetable or the fish species allows you to adapt this technique to different seasonal catches and local harvests.

• Alternative Fish: Swap the cod for halibut or mahi-mahi fillets, which share a similar firm texture that holds up beautifully inside a vegetable wrap.
• Different Wrappers: Use thin, lengthwise slices of summer yellow squash or Japanese eggplant instead of zucchini for a different flavor profile.
• Herb Variations: Substitute the fresh thyme with chopped fresh basil or oregano in the tomato bacon sauce for a more Italian-inspired finish.
• Spicy Bacon Sauce: Add 1/2 teaspoon of crushed red pepper flakes to the skillet when rendering the bacon to introduce a sharp, lingering heat.
• Cured Meat Wrap: Lay a single slice of prosciutto under the zucchini ribbons before wrapping to add an extra layer of salt and rendered fat directly to the fish.

Serving Pairings for Tomato Bacon Sauce

Pairing this rich, smoky tomato sauce and mild white fish with highly absorptive side dishes ensures no flavorful pan juices go to waste.

• Serve over grilled polenta cakes cooked on the outer flat-top ring to soak up the rendered bacon fat and tomato broth.
• Pair with a warm couscous salad tossed with grilled lemon juice and fresh parsley for a lighter, acidic contrast.
• Accompany with thick slices of rustic sourdough bread, toasted directly on the grill for 2 minutes per side to drag through the remaining sauce.

Frequently Asked Questions

Understanding the precise slicing thickness for the wrapper and the target internal temperature for the fish guarantees perfect execution on the grill.

How do you slice zucchini thin enough to wrap fish?

The most reliable tool for slicing zucchini thinly and consistently is a mandoline slicer set to exactly 1/8-inch thickness. If using a standard chef's knife, cut slowly and carefully discard any uneven or overly thick slices, as they will snap rather than bend around the delicate fillet.

What temperature should cod be cooked to on the grill?

Cod should be cooked to an internal temperature of exactly 135°F to 140°F on a digital meat thermometer. Because the fish will experience 3 to 5 degrees of carryover cooking after being removed from the heat, pulling it from the grill at 135°F ensures a flaky, moist texture without rubberiness.

Can you cook the fish and the sauce at the same time?

Yes, cooking the sauce and fish simultaneously is highly efficient on the Arteflame. You can maintain a steady simmer for the cast-iron skillet containing the tomato bacon sauce on the outer flat-top ring while utilizing the hotter zones nearer the center grate to properly sear the zucchini-wrapped cod.

Why is my zucchini unwrapping on the grill?

Zucchini unravels during grilling when the slices are cut too thick, the fish is turned too aggressively, or the ends are not properly secured. Always overlap the ends of the zucchini slices by at least one full inch and anchor them deep into the flesh of the cod using wooden toothpicks.

Elevate Your Seafood Grilling

Grilling delicate fish on a flat-top wrapped in fresh zucchini yields a presentation that looks technically demanding but is functionally effortless when you have the right heat zones at your disposal.

Combining the blistering radiant heat of the center fire with the predictable, steady warmth of the outer ring changes how you approach multi-component dishes. Gather your ingredients around the Arteflame, enjoy managing the simmering bacon sauce alongside the sizzling fish, and experience the satisfaction of cooking an entire intricate meal on one open surface.
