Baked Cod Lemon Butter

There's something about the smell of butter hitting a hot pan that pulls me into the kitchen, no matter what kind of day I've had. Years ago, I discovered cod at a farmers market stand where the fishmonger told me it was the most forgiving white fish to cook—just pat it dry and you're already halfway there. That conversation stuck with me, and now baked cod with lemon and butter has become my quiet dinner fix when I want something that feels both nourishing and a little bit elegant without the stress.

I made this for my sister the night she got back from a difficult work trip, and watching her face when she tasted it—that quiet satisfaction—reminded me that simple food cooked with care is its own kind of comfort. She asked for the recipe right there at the table, which felt like the highest compliment possible.

Ingredients

• Cod fillets (4, about 150–180 g each): Look for fillets that are pale and uniform in color, and ask the fishmonger to confirm they're boneless since that saves you hunting for surprises mid-bite.
• Olive oil (1 tbsp): This is just for a light coating and prevents sticking, so use what you have on hand.
• Sea salt and freshly ground black pepper: Sea salt dissolves better than table salt, and fresh pepper from a grinder makes a real difference in how bright the seasoning tastes.
• Unsalted butter (60 g): The sauce is where butter shines, so use good quality if you can—it's the star of the show.
• Garlic (2 cloves, minced): Don't skip the mincing step; it helps the garlic distribute evenly and prevents sharp, raw bites.
• Lemon juice and zest (1 lemon): Fresh lemon is non-negotiable here; bottled juice tastes tinny by comparison and misses the brightness that makes this dish sing.
• Fresh parsley (1 tbsp, finely chopped): This is your last-minute hero, added off the heat so it stays vibrant green and fragrant.
• Capers (1 tbsp, optional): These little briny pops are optional, but they add a sophisticated salty note that makes people wonder what your secret is.

Instructions

Set the stage:

Preheat your oven to 200°C (400°F) and line a baking dish with parchment paper or give it a light oil rub. This moment of preparation matters because it means you won't be fumbling when the fish is ready.

Dry your fish thoroughly:

Pat the cod fillets with paper towels until they feel almost dry to the touch. This step prevents the fish from steaming and gives you a better texture—it's the difference between flaky and mushy.

Oil and season:

Arrange the fillets in the dish, drizzle lightly with olive oil, and sprinkle salt and pepper evenly across each one. Taste your salt as you go by touching your fingertip to your tongue; you want enough to enhance, not overpower.

Bake until opaque:

Slide the dish into the oven for 15–18 minutes, watching until the fish turns opaque and flakes easily with a fork. This part is quick, which is why checking around the 15-minute mark keeps you in control.

Build the sauce while waiting:

While the fish bakes, melt butter in a small saucepan over medium heat and add minced garlic. Let it sizzle gently for about 1 minute until fragrant but not browned—brown garlic tastes bitter and ruins the whole thing.

Finish with brightness:

Stir in lemon juice, zest, and capers if you're using them, then simmer for 1–2 minutes before removing from heat. Toss in the fresh parsley last, off the heat so it stays vibrant.

Plate and serve:

Transfer each fillet to a plate, spoon the warm lemon butter sauce over the top, and finish with lemon slices and extra parsley. Serve immediately while everything is still warm and the flavors are at their peak.

There was an evening when I made this for someone I was trying to impress, and instead of being nervous about the cooking, I felt calm knowing that this recipe couldn't betray me. That's when it stopped being just a weeknight dish and became something I trust completely.

Pairing and Serving Ideas

This dish is beautiful on its own, but a few sides turn it into something restaurant-worthy. Steamed broccoli or green beans soak up the sauce beautifully, and a simple bed of rice gives you something to push the sauce around on. If you want to get a little fancy, try roasted asparagus or even crushed new potatoes tossed with a touch of butter and fleur de sel.

Wine and Drink Pairings

A chilled Sauvignon Blanc or Pinot Grigio is the obvious choice—the acidity cuts through the butter and mirrors the lemon brightness. If wine isn't your thing, sparkling water with a lemon wedge does the job, or a crisp pilsner if you're in a beer mood. I've even served this with a dry vermouth and soda, which sounds fancier than it is.

Variations and Substitutions

While cod is my preference because it's mild and forgiving, halibut and haddock work beautifully here and won't change the cooking time much. You can also add a whisper of white wine to the sauce, or a touch of Dijon mustard if you want it less sweet. Some nights I scatter fresh thyme leaves over the fish before baking, and other times I add a pinch of paprika or chili flakes for warmth and color.

• Try substituting the fresh parsley with dill or tarragon if you want a different herbal note.
• Capers can be swapped for green peppercorns or olives if you want to experiment.
• A touch of white wine in the sauce adds depth without changing the fundamental feel of the dish.
