Why You’ll Love This Grilled Cod with Roasted Tomatoes & Creamy Dill Sauce

This recipe is made for seafood lovers and skeptics alike. Cod is a mild white fish with a buttery texture that grills beautifully. When matched with juicy tomatoes and a silky sauce that sings with dill, lemon, and garlic, it turns into a dish that’s equal parts comforting and refreshing. You’ll also love that it’s naturally gluten-free, protein-rich, and can be made in under 30 minutes.

What Kind of Cod Should I Use?

Fresh wild-caught cod is always the top pick for flavor and texture, but frozen cod fillets work well too—just make sure they’re fully thawed and patted dry before grilling. Look for fillets that are thick and uniform in size so they cook evenly. If cod isn’t available, you can also substitute with halibut or haddock for a similar result.

Ingredients for the Grilled Cod with Roasted Tomatoes & Creamy Dill Sauce

To make this grilled cod dish truly shine, every ingredient plays a role in building layers of fresh, vibrant flavor. The star is definitely the cod, but it wouldn’t be the same without those juicy tomatoes and the creamy dill-packed sauce that ties everything together.

• Cod fillets – The base of the dish, cod is lean, mild, and cooks quickly on the grill while staying tender.
• Cherry tomatoes – Roasting these brings out their natural sweetness and adds color and brightness to the plate.
• Olive oil – Used to coat both the fish and the tomatoes, it helps everything grill and roast beautifully while adding flavor.
• Salt and pepper – Essential for seasoning and enhancing the natural taste of each component.
• Fresh dill – The hero herb of the sauce, it brings a cooling, aromatic note that perfectly complements the fish.
• Greek yogurt – This makes the sauce creamy without being heavy and adds a bit of tang.
• Garlic – Minced and stirred into the sauce for a gentle kick of flavor.
• Lemon juice – Adds brightness to both the fish and the sauce, lifting the overall taste.
• Dijon mustard – A small but mighty addition that rounds out the creamy dill sauce with a bit of bite.

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

Step 1: Prep the Tomatoes

Preheat your oven to 400°F. Spread cherry tomatoes on a baking sheet, drizzle with olive oil, and sprinkle with salt and pepper. Roast for about 20 minutes until they start to blister and caramelize.

Step 2: Make the Creamy Dill Sauce

In a small bowl, combine Greek yogurt, chopped fresh dill, minced garlic, lemon juice, Dijon mustard, salt, and pepper. Stir until smooth and well blended. Chill in the fridge while the rest cooks.

Step 3: Grill the Cod

Preheat your grill to medium-high heat. Pat the cod fillets dry, brush lightly with olive oil, and season with salt and pepper. Grill for about 3-4 minutes on each side, depending on thickness, until the fish flakes easily with a fork.

Step 4: Plate and Serve

Place the grilled cod on a serving plate, top with the roasted tomatoes, and spoon over the chilled dill sauce. Garnish with a bit more fresh dill or a squeeze of lemon if desired.

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

This dish is best served hot and fresh off the grill while the cod is tender and flaky and the tomatoes are still warm and bursting with flavor. Spoon the chilled dill sauce over just before serving for a beautiful contrast in temperature and texture. Each serving is satisfying without being heavy, making it perfect for warm-weather dining or a light dinner any night of the week. This recipe serves 4 people comfortably.

If you have leftovers, store the grilled cod and roasted tomatoes in an airtight container in the fridge for up to 2 days. Keep the dill sauce separate in a small jar or container so it doesn’t make the fish soggy. Reheat the cod gently in the oven or a skillet—avoid microwaving if you can, to preserve its texture.
