Grilled Cod Roasted Tomatoes Dill
There's something magical about the smoky char of grilled cod meeting the sweet acidity of roasted tomatoes and the bright punch of fresh dill. Home cooks adore this dish for its elegant simplicity-it feels like a restaurant meal but comes together in under 30 minutes. Perfect for weeknight dinners when you crave something special or weekend gatherings where you want to impress without stress. The combination of textures and flavors is irresistibly balanced, making it a go-to recipe that never disappoints.
What Makes This Recipe Special
- The roasted cherry tomatoes caramelize beautifully, concentrating their natural sugars to create a sweet-tart contrast with the delicate, flaky cod.
- Grilling the cod instead of pan-searing adds a smoky depth that elevates the dish to restaurant-quality without extra effort.
- The dill sauce is enriched with heavy cream and a touch of butter (optional) for luxurious texture, but it stays light enough to let the fish shine.
- This recipe balances hands-on time (grilling the fish) with hands-off time (roasting tomatoes and simmering sauce), making it efficient for busy cooks.

Instructions
1
Preheat oven to 425°F (220°C). Place cherry tomatoes on a baking sheet, drizzle with olive oil, sprinkle with salt and pepper, and roast for 15–20 minutes until blistered.
2
Pat cod fillets dry, rub with olive oil, season with salt, pepper, and a bit of dill.
3
Heat grill or grill pan over medium-high heat. Grill cod for 3–4 minutes per side, or until opaque and flaky.
4
In a small saucepan, melt butter (if using) and sauté garlic for 30 seconds. Add cream, lemon juice, dill, salt, and pepper. Simmer on low for 3–5 minutes, stirring until slightly thickened.
5
Plate by spooning sauce onto each dish, topping with tomatoes and placing grilled cod over everything. Garnish with fresh dill. Serve immediately.
Essential Tips
Pat the cod dry
Ensure the fillets are thoroughly patted dry with paper towels before grilling. This removes excess moisture, helping the fish achieve a crispy, golden crust that locks in flavor and prevents sticking.
Don't overcook the fish
Grill the cod for just 3-4 minutes per side. The flesh should flake easily with a fork and look opaque throughout. Overcooking will make it dry and rubbery-remember, the fish will continue to cook slightly off the grill.
Roast tomatoes in batches
If you're roasting a large quantity of tomatoes, spread them in a single layer on the baking sheet. Overcrowding steams them instead of roasting, which dulls their sweetness and prevents caramelization.
Simmer the sauce gently
Keep the cream sauce at a low simmer, stirring occasionally, to prevent it from splitting or curdling. If it thickens too quickly, a splash of water or broth can loosen it while maintaining its creamy texture.
Garnish last-minute
Add fresh dill right before serving to preserve its vibrant color and delicate aroma. Sprinkling it on too early can cause it to wilt and turn dull in color.
Smart Swaps & Variations
Herb Swap
Replace fresh dill with tarragon or chervil for a subtle anise or parsley-like flavor that complements the cod beautifully.
Tomato Free
Skip the tomatoes and fold in sautéed leeks or caramelized fennel for a mellow, slightly sweet base instead.
Dairy-Free
Use coconut cream or cashew cream in place of heavy cream, and olive oil instead of butter to keep the sauce rich and silky.
Spicy Kick
Add a pinch of red pepper flakes to the dill sauce or top the dish with pickled jalapeños for a bright, tangy contrast.
What to Serve With This
- Crusty sourdough bread, toasted and rubbed with garlic for soaking up the dill sauce.
- A crisp green salad with arugula, shaved fennel, and a light lemon vinaigrette to cut through the richness.
- Steamed asparagus or roasted broccoli for a simple, nutritious side that pairs well with seafood.
- Chilled white wine like Sauvignon Blanc or Pinot Grigio to enhance the citrus and herbal notes.
Storage & Reheating
Storage
Store leftovers in an airtight container in the refrigerator for up to 2 days. Keep the sauce and fish separate to prevent the cod from becoming soggy.
Reheating
Reheat the sauce gently in a small saucepan over low heat. Gently warm the cod in a covered skillet with a splash of water or broth to restore moisture, avoiding direct heat which can dry it out.
Expert Chef Tips
- Use a grill basket or cedar plank for the cod if you're worried about it falling through the grates. This also adds a subtle smoky flavor and makes flipping easier.
- For extra depth in the dill sauce, steep a dill sprig in the warm cream for 5 minutes before removing it. This infuses the sauce with a more complex herbal note.
- If your cream sauce splits, whisk in a teaspoon of cold water or a splash of lemon juice to bring it back together. The emulsification can be rescued with a little patience and gentle stirring.
Equipment You’ll Need
- Grill or grill pan (cast iron preferred for even heat)

Frequently Asked Questions
Can I substitute another fish for cod?
Yes! Halibut, sea bass, or mahi-mahi work well due to their firm texture. Avoid flaky fish like tilapia, as they may break apart during grilling. Adjust cooking time to 4-5 minutes per side, depending on thickness.
What's the best way to grill cod without sticking?
Make sure the grill grates are clean and preheated. Lightly oil the grates with a paper towel dipped in oil and held with tongs. Also, ensure the cod is dry and the grill is hot before placing the fish down.
Can I make the dill sauce ahead of time?
Yes! Prepare the sauce up to 2 days in advance and store it in the fridge. Reheat gently over low heat, stirring frequently, and thin with a splash of water or broth if needed before serving.
How do I prevent the tomatoes from burning while roasting?
Toss them with enough olive oil to coat lightly and spread them in a single layer on the baking sheet. Roast at 425°F (220°C) and stir halfway through. If they start to darken too quickly, reduce the oven temperature slightly.
Is there a way to make this dish lower in fat?
Absolutely. Use half-and-half or evaporated milk instead of heavy cream, and skip the butter entirely. The dish will still be rich and flavorful while cutting calories and saturated fat significantly.
Can I use dried dill instead of fresh?
Yes, but reduce the amount by half and add it to the sauce while it simmers to rehydrate. Fresh dill has a brighter, more complex flavor, so use it if possible for the best results.
What's the best way to reheat the cod without drying it out?
Place the cod in a covered skillet with a tablespoon of water or broth over low heat. Let it steam gently for 2-3 minutes until warmed through. Avoid microwaving, as it can make the fish rubbery.
Can I add other vegetables to the roasting tray?
Yes! Baby potatoes, carrots, or zucchini work well. Cut them into even-sized pieces and roast alongside the tomatoes for 20-25 minutes, adding the cod to the grill afterward.
