The magic is in the balance. Lemon brings brightness, garlic adds warmth, and a touch of butter rounds everything out.

Cod is a mild, lean fish that soaks up flavor without becoming heavy, so the lemon-garlic combo really shines. A quick bake keeps the fish moist and flaky, while a light brush of olive oil helps prevent drying. A sprinkle of fresh herbs at the end adds a clean, fragrant finish.

What You’ll Need

Cod fillets (1.5–2 pounds), skinless, about 1 to 1.5 inches thick
Lemons (2) for juice and zest
Fresh garlic (3–4 cloves), minced
Unsalted butter (3 tablespoons), melted
Olive oil (1 tablespoon)
Salt (1 to 1.5 teaspoons), to taste
Black pepper (1/2 teaspoon), freshly ground
Smoked paprika or sweet paprika (1/2 teaspoon) for color and warmth
Crushed red pepper flakes (optional, 1/4 teaspoon) for a mild kick
Fresh parsley (2 tablespoons), chopped
Lemon slices for garnish
Optional add-ins: capers, a splash of dry white wine, or a handful of cherry tomatoes

How to Make It

Cooking process: Cod fillets baking at 400°F in a lightly greased enamel pan, even brush of melted

Preheat and prep: Heat your oven to 400°F (200°C).Lightly grease a baking dish large enough to hold the cod in a single layer.
Pat dry and season: Pat the cod fillets dry with paper towels. Season both sides with salt, pepper, and paprika. Drying helps the seasoning stick and prevents steaming.
Make the sauce: In a small bowl, whisk together melted butter, olive oil, minced garlic, lemon zest, and the juice of one lemon.Add red pepper flakes if using.
Arrange the fish: Place cod in the baking dish. Spoon the lemon-garlic butter evenly over the fillets. Nestle a few lemon slices around and on top.If using capers or tomatoes, scatter them in the dish now.
Bake: Bake uncovered for 12–18 minutes, depending on thickness. Cod is done when it flakes easily with a fork and reaches 145°F (63°C) in the thickest part.
Rest and finish: Remove from the oven and let it rest for 2 minutes. Sprinkle with chopped parsley and an extra squeeze of lemon if you like.
Serve: Spoon the pan sauce over each piece.Great with rice, couscous, buttered potatoes, or steamed greens.

How to Store

Refrigerate: Cool completely, then store in an airtight container for up to 2 days. Keep the sauce with the fish to prevent drying.
Reheat: Warm gently at 275–300°F (135–150°C) for 8–10 minutes, or microwave at 50% power in short bursts. Avoid overcooking.
Freezing: Not ideal for baked cod, as the texture can turn mushy.If you must, freeze up to 1 month and thaw overnight in the fridge.
Leftover ideas: Flake the fish into tacos, fold into a lemony pasta, or add to a grain bowl with greens and extra lemon.

Pitfalls to Watch Out For

Overcooking: Cod dries out quickly.Start checking at 12 minutes, especially for thinner fillets.
Too much lemon juice: Extra acid can overpower the fish. Use zest for brightness without making it sour.
Skipping the pat-dry step: Wet fish can steam instead of bake, leading to a watery sauce and bland flavor.
Uneven thickness: If fillets vary in size, remove thinner pieces earlier or fold the thin end under to even them out.
Not enough salt: Cod is mild. Taste the sauce and season generously so the flavors pop.

Alternatives

Different fish: Try haddock, halibut, pollock, or tilapia.Adjust baking time based on thickness.
Dairy-free: Swap butter for more olive oil or a vegan butter alternative.
Herb twist: Use dill, chives, basil, or thyme instead of parsley. A mix of parsley and dill is classic with fish.
Breadcrumb topping: Combine panko with a little olive oil, lemon zest, parsley, and a pinch of salt. Sprinkle on top for crunch during the last 6–8 minutes.
Pan-seared finish: For a slight crust, sear cod in a hot skillet with oil for 2 minutes per side, then finish in the oven with the lemon-garlic butter.
Wine sauce: Add 2–3 tablespoons of dry white wine to the baking dish for a subtle, fragrant sauce.

FAQ

How do I know when cod is done?

The fish should flake easily with a fork and look opaque throughout.

An instant-read thermometer should read 145°F (63°C) in the thickest part. If it still looks translucent, give it another minute or two.

Can I use frozen cod?

Yes, but thaw completely in the fridge overnight and pat dry very well. Excess moisture can dilute the sauce and affect texture.

What sides go well with lemon garlic baked cod?

Try herbed rice, couscous, roasted baby potatoes, sautéed spinach, asparagus, or a simple green salad.

Crusty bread is great for soaking up the sauce.

Can I make it ahead?

You can mix the lemon-garlic butter and prep the baking dish ahead of time. Season and bake the fish right before serving for the best texture.

Why use both lemon juice and zest?

Juice brings tartness, while zest adds pure lemon aroma without extra acidity. Using both gives a brighter, fuller lemon flavor.

Is cod sustainable?

Look for cod certified by reputable organizations like the MSC, or ask your fishmonger for sustainably sourced options.

Haddock and pollock can be good alternatives.

Can I add vegetables to the pan?

Yes. Cherry tomatoes, thinly sliced zucchini, or asparagus work well. Add firmer veggies (like potatoes) only if par-cooked, since cod cooks quickly.

What if I don’t like garlic?

Use less garlic or swap in shallots or thinly sliced green onions.

You’ll still get a tasty, aromatic sauce with softer bite.

How do I prevent a watery sauce?

Pat the fish very dry, don’t overcrowd the pan, and avoid frozen fish that isn’t fully thawed. A small baking dish that just fits the fish is best.

Can I grill instead of bake?

Yes. Place cod on a well-oiled grill-safe pan or foil pack.

Grill over medium heat for 8–12 minutes, adding the lemon-garlic butter on top. Check for doneness as usual.
