The Key Ingredients for Success
The beauty of this recipe lies in its simplicity. We’re using a handful of fresh, flavorful ingredients to create a truly memorable dish.
For the Baked Cod:
- Cod Fillets: Look for thick, high-quality cod fillets, about 1.5 inches thick. This ensures the fish cooks evenly and doesn’t dry out.
- Olive Oil: A good quality extra virgin olive oil adds flavor and helps the fish stay moist.
- Garlic: Freshly minced garlic provides a fragrant, aromatic base.
- Salt & Pepper: Simple seasonings are all you need to let the flavor of the cod shine.
For the Creamy Lemon-Dill Sauce:
- Greek Yogurt: This is the secret to a creamy, tangy sauce that’s much lighter than mayonnaise-based alternatives.
- Fresh Dill: The star of the show! Its fresh, slightly anise-like flavor is the perfect partner for lemon and fish.
- Lemon: We use both the zest and juice for a bright, powerful citrus punch.
- Dijon Mustard: Adds a subtle tang and helps to emulsify the sauce.
How to Make Baked Cod with Lemon-Dill Sauce (Step-by-Step)
Making this dish is incredibly straightforward. Just follow these simple steps for a perfect result every time.
- Preheat and Prep: Start by preheating your oven to 400°F (200°C). Pat the cod fillets completely dry with a paper towel; this is crucial for getting a nice texture.
- Season the Cod: Place the fillets in a baking dish. Drizzle with olive oil and sprinkle with minced garlic, salt, and pepper. Gently rub the seasonings over the fish.
- Bake to Perfection: Bake for 12-15 minutes. The exact time will depend on the thickness of your fillets. The cod is done when it flakes easily with a fork and is opaque throughout.
- Whip Up the Sauce: While the cod is baking, combine the Greek yogurt, chopped fresh dill, lemon zest, lemon juice, and Dijon mustard in a small bowl. Stir until smooth and well combined. Season with a pinch of salt and pepper to taste.
- Serve Immediately: Once the cod is cooked, remove it from the oven. Serve it warm with a generous dollop of the lemon-dill sauce on top.

Pro-Tips for Perfectly Flaky Cod Every Time
Want to guarantee your baked cod is moist and delicious? Follow these simple tips from a seasoned culinary guide.
- Don’t Overbake: This is the most common mistake. Fish cooks quickly! Check it at the 12-minute mark. As soon as it flakes easily, it’s done. Carryover heat will continue to cook it slightly after you remove it from the oven.
- Use Thick Fillets: Thicker pieces of cod (around 1.5 inches) are more forgiving and less likely to dry out than their thinner counterparts.
- Bring Fish to Room Temp: Let the cod sit on the counter for about 15 minutes before baking. This helps it cook more evenly.
Delicious Serving Suggestions
This Baked Cod with Lemon-Dill Sauce is wonderfully versatile. For a complete and satisfying meal, pair it with roasted vegetables like these amazing roasted carrots or simple steamed asparagus. It’s also fantastic with a side of quinoa, fluffy rice, or even some creamy mashed potatoes.
If you’re looking for a lighter option, a fresh green salad with a simple vinaigrette is all you need. And for a truly delightful Mediterranean-inspired feast, start with some Prosciutto-Wrapped Mozzarella before the main course.

Hosting a dinner party? Consider adding some Grilled Shrimp Bowls to the menu for a fantastic surf-and-turf theme.
Storing and Reheating Leftovers
While this dish is best enjoyed fresh, leftovers can be stored in an airtight container in the refrigerator for up to 2 days. To reheat, gently warm the cod in a 275°F (135°C) oven until just heated through, which helps prevent it from drying out. Store the sauce separately in the fridge. We do not recommend freezing this dish.
Answering Your Questions
Yes, you can. For best results, thaw the frozen cod completely in the refrigerator overnight. Before cooking, make sure to pat it very dry with paper towels to remove excess moisture, which helps it bake perfectly.
The best way to tell is by texture and appearance. The cod should be opaque and flake easily when gently pressed with a fork. If you use a thermometer, the internal temperature should reach 145°F (63°C).
The Greek yogurt-based sauce can be made ahead and stored in an airtight container in the refrigerator for up to 3 days. It’s a great way to save time on busy weeknights!
This dish pairs beautifully with many sides. We recommend roasted asparagus, garlic-parmesan carrots, steamed green beans, quinoa, or a light cucumber salad.
While fresh dill provides the best flavor, you can substitute it with 1 tablespoon of dried dill in a pinch. You could also use other fresh herbs like parsley or chives for a different flavor profile.
