Preparation Phase & Tools to Use

To get the best results from your Grilled Cod with Roasted Tomatoes & Creamy Dill Sauce, your tools matter just as much as your ingredients. Here’s what you’ll need:

• Cast Iron Grill Pan or Outdoor Grill: A heavy-duty grill pan creates those signature char lines and helps evenly cook the cod while keeping it moist inside. An outdoor grill will offer a smokier depth.
• Baking Sheet: Essential for roasting the tomatoes to blistered perfection. A rimmed sheet ensures juices don’t escape and makes cleanup easier.
• Fish Spatula: Designed to slide gently under delicate fillets without breaking them. It also helps keep the golden sear intact.
• Small Saucepan: For gently simmering the creamy dill sauce. A saucepan gives you control over the heat and texture.
• Tongs: Useful for turning tomatoes and maneuvering food safely over high heat.

Having these tools on hand ensures a seamless cooking experience and the confidence to present a dish that’s as beautiful as it is delicious.

How To Make the Grilled Cod with Roasted Tomatoes & Creamy Dill Sauce

Step 1: Prepare the Tomatoes

Preheat your oven to 400°F (200°C). Toss cherry tomatoes with olive oil, salt, and pepper on a baking sheet. Roast for 20-25 minutes until they blister and soften.

Step 2: Grill the Cod

Season cod fillets with salt and pepper. Heat a grill pan over medium-high heat and add a bit of olive oil. Grill the cod 3-4 minutes per side until opaque and grill-marked. Use a fish spatula for gentle flipping.

Step 3: Make the Creamy Dill Sauce

In a small saucepan, heat a splash of olive oil and sauté minced garlic until fragrant. Add heavy cream and simmer until slightly thickened. Stir in fresh dill and lemon juice, adjusting salt and pepper to taste.

Step 4: Assemble the Plate

Spoon the dill sauce onto the base of your serving dish. Add a generous handful of roasted tomatoes and gently place the grilled cod on top. Garnish with extra dill.

How to Serve and Store Grilled Cod with Roasted Tomatoes & Creamy Dill Sauce

Serve this dish while the cod is still warm and the sauce silky. Plate the creamy dill sauce as a base, then layer the charred tomatoes followed by the cod. A sprig of fresh dill or a thin lemon slice makes for a simple, elegant garnish. This pairs well with steamed asparagus, herbed rice, or crusty bread.

For storing, place leftovers in an airtight container in the fridge for up to 2 days. Reheat gently over low heat to preserve the delicate texture of the fish and prevent the cream sauce from breaking. Avoid microwaving if possible—a covered skillet works best.

Frequently Asked Questions

How do I know when cod is perfectly cooked?

The fish should be opaque and flake easily with a fork. It typically takes 3-4 minutes per side on medium-high heat. Avoid overcooking to keep it juicy.

Can I substitute another fish for cod?

Yes, you can use haddock, halibut, or sea bass—all have mild flavors and firm textures that hold up well to grilling and saucing.

Is there a dairy-free version of the dill sauce?

Absolutely. Swap the heavy cream for full-fat coconut milk and ensure your butter (if used) is plant-based. The flavor will change slightly, but the sauce remains rich and delicious.

Can I make this ahead?

You can roast the tomatoes and prepare the dill sauce ahead of time. Grill the cod fresh for the best taste and texture. Reheat components gently before serving.

What wine pairs well with this dish?

A crisp Sauvignon Blanc or a light Chardonnay works beautifully. Their acidity complements the dill and lemon while balancing the richness of the sauce.

Can I use dried dill instead of fresh?

Fresh dill is best for this recipe, but if needed, use one-third the amount of dried dill. Add it early during the sauce cooking to release its flavors.
