Ingredients Breakdown

Here’s what you’ll need to make this refreshing baked cod with lemon-dill sauce:

For the Cod:

• 4 cod fillets (about 6 oz each): Cod is a white, flaky, mild-tasting fish that bakes beautifully. Look for fresh or properly thawed fillets.
• 2 tablespoons olive oil: Helps to crisp up the edges and keep the cod moist.
• Salt and pepper, to taste: Enhances the natural flavor of the fish.
• 1 teaspoon garlic powder: Adds a savory base.
• 1 teaspoon paprika (optional): For a hint of warmth and color.
• Lemon slices, for garnish: Adds brightness and visual appeal.

For the Lemon-Dill Sauce:

• 1/3 cup plain Greek yogurt or sour cream: A creamy base that provides a tangy bite.
• 2 tablespoons mayonnaise (optional): For extra richness; skip it for a lighter version.
• 1 tablespoon fresh dill, finely chopped (or 1 teaspoon dried): The star herb of the sauce — fresh dill really makes a difference.
• 1 tablespoon lemon juice, freshly squeezed: Brightens up the sauce.
• 1 teaspoon lemon zest: Adds citrusy depth.
• 1 teaspoon Dijon mustard: A touch of heat and tang.
• 1 small garlic clove, minced (optional): For a bold, savory note.

Step-by-Step Instructions

Step 1: Prep and Preheat

Preheat your oven to 400°F (200°C). Line a baking dish or sheet pan with parchment paper or lightly grease it with olive oil. Pat the cod fillets dry using paper towels — this helps them brown and prevents steaming.

Step 2: Season the Cod

Place the cod fillets in the prepared dish. Drizzle with olive oil, then sprinkle evenly with garlic powder, paprika (if using), salt, and pepper. Rub gently to coat the fish on both sides. Place a slice of lemon on top of each fillet if desired.

Step 3: Bake the Fish

Transfer the dish to the oven and bake the cod for 12–15 minutes, or until the fish flakes easily with a fork. The exact time will depend on the thickness of your fillets. A good rule of thumb is 10 minutes per inch of thickness.

Step 4: Make the Lemon-Dill Sauce

While the cod bakes, prepare the sauce. In a small bowl, whisk together the Greek yogurt or sour cream, mayonnaise (if using), dill, lemon juice, zest, Dijon mustard, and minced garlic. Taste and season with a pinch of salt and pepper. For extra zing, add more lemon juice to taste.

Step 5: Serve and Enjoy

Once the cod is cooked, plate each fillet and spoon the lemon-dill sauce on top or serve it on the side. Garnish with additional dill or lemon wedges, if desired. Serve hot and enjoy!

Pro Tips for Success

• Use fresh cod if possible: It has a better texture and flavor than frozen, but frozen will still work if fully thawed and patted dry.
• Don’t overbake: Cod is a delicate fish and can become dry quickly. Pull it out as soon as it flakes easily.
• Double the sauce: It’s so delicious, you might want extra for dipping veggies or potatoes.
• Prep ahead: You can make the lemon-dill sauce a day in advance and store it in the fridge — the flavors will deepen overnight.

What to Serve With Baked Cod

This dish pairs wonderfully with a variety of sides. Here are a few serving ideas:

• Roasted baby potatoes or garlic mashed potatoes
• Steamed asparagus, green beans, or zucchini
• Rice pilaf, quinoa, or couscous
• Simple mixed greens salad with a lemon vinaigrette

Variations and Swaps

• Swap the cod: This method works well with halibut, haddock, tilapia, or even salmon.
• Go spicy: Add a pinch of cayenne or red pepper flakes to the seasoning.
• Make it dairy-free: Use a dairy-free yogurt alternative in the sauce.
• Make it crispy: Coat the cod in panko breadcrumbs before baking for added crunch.
• Add herbs: Mix in chopped chives or parsley with the dill for more herbal flavor.

Storing and Reheating

To Store: Let the baked cod cool completely, then transfer it to an airtight container. Refrigerate for up to 3 days. Store the sauce separately for best texture.

To Reheat: Gently reheat in the oven at 300°F (150°C) for 8–10 minutes, or microwave on 50% power in 30-second intervals. Avoid overheating to prevent drying out the fish.

FAQs

Can I use frozen cod?

Yes! Just be sure to thaw it completely and pat it dry before baking. Excess moisture can prevent it from browning and lead to mushy texture.

How do I know when cod is done baking?

When cod is fully cooked, it turns opaque and flakes easily with a fork. If you’re using a thermometer, the internal temperature should reach 145°F (63°C).

Is cod a healthy fish?

Definitely. Cod is low in fat, high in protein, and a great source of vitamins B12 and B6. This recipe keeps it light and nutritious with a yogurt-based sauce.

What if I don’t like dill?

You can substitute fresh parsley, chives, or tarragon for a different herby flavor.

Can I grill the cod instead?

Yes! Grill the seasoned cod fillets over medium-high heat for 3–4 minutes per side. Use a grill basket or foil to keep them from falling apart.
