The smell of lemon and dill wafting from the oven signals dinner is almost ready. This baked cod takes just 25 minutes but tastes like you spent an hour on it.
I still remember the first time I made baked cod for my family on a busy Tuesday night. I was skeptical that something so simple could satisfy everyone, but the combination of tender, flaky fish with that bright lemon-dill sauce won them over instantly. Now it’s become our go-to when we want something light yet satisfying.

Ingredients for Lemon Dill Baked Cod
I always reach for the freshest cod fillets I can find because quality makes a noticeable difference in texture and flavor. Look for firm, white flesh with no fishy smell, and if you can grab wild-caught, it’ll bake up even better with a firmer texture.
For the Cod:
- 4 cod fillets (about 6 oz each, firm white flesh)
- 2 tablespoons olive oil (extra virgin) – I recommend using a good quality oil for best flavor
- Salt and pepper to taste
- 1 teaspoon garlic powder
- 1 teaspoon paprika (optional, adds subtle warmth)
- Fresh lemon slices for garnish
For the Lemon-Dill Sauce:
- ½ cup plain Greek yogurt (or sour cream) – My preference is Greek yogurt for a lighter option; I usually use Fage or Chobani
- 2 tablespoons mayonnaise (optional, adds extra creaminess)
- 2 tablespoons fresh dill (or 2 teaspoons dried) – In my experience, fresh dill gives the brightest flavor
- 2 tablespoons fresh lemon juice (from about 1 lemon)
- 1 teaspoon lemon zest – I usually zest before juicing for easier prep
- 1 teaspoon Dijon mustard
- 1 garlic clove, minced (optional)
- Salt and pepper to taste
Step-by-Step Instructions
I recommend preheating your oven before you prep the fish so everything stays on schedule for that 25-minute timeline.
Step 1: Preheat your oven to 400°F and line a baking sheet with parchment paper. This prevents sticking and makes cleanup effortless.
Step 2: Arrange the cod fillets on the prepared baking sheet, leaving space between each piece. Drizzle with olive oil, then season both sides with salt, pepper, garlic powder, and paprika if using. Gently press the spices into the flesh to help them adhere during baking.
Step 3: Slide the baking sheet onto the middle oven rack and bake for 12 to 15 minutes, checking at the 12-minute mark. Gently press the thickest part with a fork – the fish is done when it turns opaque throughout and separates into large flakes easily. The internal temperature should reach 145°F. Avoid overbaking or the texture becomes dry.
Step 4: While the cod bakes, combine Greek yogurt, mayonnaise, fresh dill, lemon juice, lemon zest, Dijon mustard, and minced garlic in a small bowl. Season with salt and pepper, then whisk until smooth and well combined. The sauce should be creamy with visible flecks of green dill. This sauce can be made up to 2 days ahead and stored in the refrigerator.
Step 5: Once the cod is perfectly cooked, transfer each fillet to a serving plate using a spatula. Spoon a generous amount of the lemon-dill sauce over the top and garnish with fresh lemon slices. Serve immediately while the fish is warm and tender.
Perfect Pairings for Lemon Dill Baked Cod
This light, protein-rich fish pairs beautifully with sides that add texture and substance without overwhelming the delicate flavors.
Roasted Garlic Parmesan Potatoes: Golden, crispy potatoes provide a satisfying starch that balances the lean protein while their mild flavor lets the lemon-dill sauce shine. The garlic and parmesan add an extra layer of savory depth.
Sheet Pan Roasted Vegetables: Tender asparagus spears or a colorful medley of seasonal vegetables add a fresh, slightly earthy note that complements the bright citrus and herb flavors perfectly, plus they cook in the same timeframe as the fish.
Fluffy Coconut Rice: Simple rice provides a neutral base that soaks up the tangy lemon-dill sauce, making every bite delicious. The subtle coconut flavor adds tropical undertones without overpowering the fish.
Wild Rice Pilaf: Nutty wild rice adds extra protein and a hearty texture while maintaining the healthy profile of this meal. Its earthy flavor pairs wonderfully with the bright lemon notes.
Cucumber Tomato Salad: A chilled, crunchy salad with cucumber and cherry tomatoes provides refreshing contrast to the warm, creamy fish dish, especially welcome during warmer months.
Steamed Green Beans: Lightly steamed green beans with a hint of garlic add a crisp-tender vegetable element that rounds out the meal nutritionally and texturally without competing with the delicate fish.
Storing and Reheating Your Baked Cod
Store leftover cod in an airtight container in the refrigerator for up to 3 days. Keep the sauce separate to maintain the best texture for both components. The fish stays freshest when stored properly and away from strong-smelling foods.
When reheating, use a low oven temperature around 350°F for about 8 to 10 minutes until just warmed through and reaches 145°F internally. I recommend adding a splash of water or broth to the baking dish and covering with foil to prevent the fish from drying out. High heat causes the protein to become rubbery, so low and slow is key. Make fresh sauce if possible, as the dairy-based sauce tastes best when newly prepared.
For freezing, bake and cool the cod completely before wrapping individual portions tightly in foil or parchment, then store in freezer bags for up to 1 month. Reheat frozen fillets at 350°F for 20 to 25 minutes, checking that the internal temperature reaches 145°F. Skip freezing the sauce and whip up a fresh batch when you’re ready to serve.
FAQs
Can I use frozen cod fillets for this recipe?
Yes, but make sure to thaw them completely in the refrigerator overnight and pat them very dry with paper towels before seasoning. Excess moisture can prevent proper browning and affect texture.
What can I substitute for fresh dill?
Dried dill works well at 2 teaspoons for every 2 tablespoons of fresh. You can also try fresh parsley or chives for a different but equally delicious herb profile in the sauce.
How do I know when the cod is perfectly cooked?
The fish should reach an internal temperature of 145°F and flake easily when pressed with a fork. It will turn from translucent to opaque white throughout, with no raw-looking center remaining. The flesh should separate into large, moist flakes.
