Ingredients You'll Need
Great baked cod starts at the seafood counter. Look for fillets that are translucent, almost pearly, with a gentle ocean scent—never “fishy.” If you can, choose thicker center-cut pieces (at least 1 inch) so they stay juicy in the oven. Atlantic cod is classic, but Pacific lingcod or sustainable haddock work beautifully too.
Extra-virgin olive oil forms the base of our quick marinade. A fruity, peppery oil complements the mild fish without overwhelming it. If you’re out, avocado oil or melted ghee are fine stand-ins.
Fresh dill is non-negotiable for me in this dish. Its faint anise note marries perfectly with lemon and makes everything taste like spring. Buy a large bunch, rinse well, and spin dry; the tender fronds go into the marinade while the sturdy stems flavor the baking sheet. No dill? Tarragon, chervil, or flat-leaf parsley are happy alternatives.
Lemon does double duty: zest for bright perfume and juice for gentle acidity that “cooks” the surface of the fish and locks in moisture. Choose heavy, thin-skinned fruit—they’re juicier. A microplane grater makes quick work of the zest without any bitter white pith.
Garlic adds subtle depth. One small clove, grated on the same microplane, melts into the marinade and disappears during baking, leaving behind a whisper of savoriness.
Sea salt & freshly ground black pepper are essential. I like flaky salt for seasoning the fish directly; it adheres better and dissolves quickly.
Paprika—just a pinch—gives the finished fillets a delicate blush and gentle smokiness. Sweet Hungarian paprika is my go-to, but smoked paprika is delicious if you want a whisper of campfire flavor.
Optional but lovely: A handful of thin lemon slices roast alongside the fish, caramelizing at the edges and creating instant sauce when squeezed over the plate. Add a few capers or olives for a briny pop, or scatter cherry tomatoes around the pan for a colorful sheet-pan supper.
How to Make Baked Cod with Lemon and Dill for a Light Dinner
Preheat & Prep Pan
Position rack in center of oven and preheat to 400 °F (204 °C). Line a rimmed baking sheet with parchment paper for easiest cleanup. Lightly brush or spray the parchment with olive oil so the fish doesn’t stick.
Make the Lemon-Dill Marinade
In a small bowl, whisk together 3 Tbsp extra-virgin olive oil, zest of 1 lemon, 2 Tbsp fresh lemon juice, 1 small grated garlic clove, 2 Tbsp chopped fresh dill, ½ tsp sea salt, ¼ tsp black pepper, and ¼ tsp paprika. The mixture should smell like sunshine and herbs.
Pat Fish Dry
Gently blot 1½–2 lb (680–900 g) cod fillets with paper towels. Removing surface moisture helps the marinade cling and encourages quick, even cooking.
Marinate Briefly
Place fillets in a shallow dish and spoon ¾ of the marinade over top, turning to coat. Let stand 10–15 minutes while the oven finishes heating. Longer is fine—up to 24 hours covered in the fridge—but even a quick kiss of lemon and dill makes a difference.
Arrange on Sheet Pan
Transfer fillets to the prepared pan, skin-side down if applicable. Leave at least ½ inch between pieces for proper air circulation. Scatter optional lemon slices and cherry tomatoes around the fish; drizzle them with the remaining marinade.
Bake to Perfection
Slide pan into oven and bake 10–14 minutes, depending on thickness. Thin tails may flake at 8 minutes; thick center cuts might need 15. The cod is done when it turns opaque, feels firm to the touch, and registers 140–145 °F (60–63 °C) on an instant-read thermometer. Carry-over heat will nudge it to the USDA-recommended 145 °F.
Rest & Garnish
Remove pan from oven and let fish rest 3 minutes. This pause allows juices to redistribute, ensuring every bite is succulent. Finish with a shower of fresh dill fronds, an extra squeeze of lemon, and a drizzle of the flavorful pan juices.
Serve Light & Bright
Plate over a tangle of baby arugula, alongside fluffy quinoa, or with crusty bread to mop up the lemony juices. A crisp Sauvignon Blanc or sparkling water with cucumber ribbons completes the breezy vibe.
Expert Tips
Watch the Temp
Fish continues cooking after it leaves the oven. Pull at 140 °F for perfectly moist flakes.
Broil for Color
Need golden tops? Switch to broil for the final 1–2 minutes, but watch closely.
Keep It Juicy
Lay thin lemon slices directly on the fish; they act as “mini-umbrellas,” trapping steam.
Frozen Fish Hack
Thaw overnight in fridge, then press between towels to remove excess water before marinating.
Skin-On or Off?
Skin doesn’t crisp here; remove for easier eating or bake skin-down and slide off after.
Make-Ahead Marinade
Whisk the marinade in a jar; keeps 5 days chilled. Shake and pour whenever fish is on the menu.
Variations to Try
-
Mediterranean: Swap dill for oregano and basil, add olives and capers, finish with a splash of white wine in the final 5 minutes of baking.
-
Asian-Inspired: Replace olive oil with toasted sesame oil, use lime instead of lemon, add ginger and cilantro, sprinkle with sesame seeds.
-
Spicy: Whisk ¼ tsp chili flakes or 1 tsp harissa into the marinade; serve with cooling yogurt-dill sauce.
-
Buttery Luxury: Dot each fillet with 1 tsp cold butter before baking; baste with melted butter mid-way for silken texture.
-
Panko Crunch: Mix ¼ cup panko with 1 tsp olive oil and a pinch of paprika; press onto fish for the last 4 minutes under broiler.
-
Vegetable-Loaded: Surround fillets with asparagus spears and zucchini ribbons; everything roasts together in harmonious 12-minute harmony.
Storage Tips
Refrigerate
Cool leftovers within 2 hours, transfer to airtight container, and refrigerate up to 3 days. Store any pan juices separately; they solidify like herb-flecked lemon butter and are delicious over rice.
Freeze
Wrap each cooled fillet tightly in parchment, then foil; freeze up to 2 months. Thaw overnight in fridge and reheat gently (see below).
Reheating Without Drying Out
Warm covered in a 275 °F oven with a splash of broth or white wine for 8–10 minutes. Alternatively, microwave at 50 % power in 30-second bursts until just heated through. Avoid high heat; it turns delicate flakes rubbery.
