Baked Cod with Lemon

There's something almost meditative about watching a piece of cod transform in the oven—how the flesh turns from translucent to opaque, how the kitchen fills with the scent of lemon and briny capers. I discovered this recipe on a Tuesday evening when I had exactly twenty minutes and very little patience for complicated cooking. The result was so unexpectedly elegant that I've made it countless times since, each time realizing it's the kind of dish that feels both effortless and intentional.

I made this for my friend Marcus who'd just moved back to the city and was convinced he'd forgotten how to cook for himself. Watching his face when he took that first bite—when he realized how simple good food could be—that's when I knew this recipe was keeper. He now makes it every Friday and swears by it.

Ingredients

• Cod fillets: Look for pieces that are roughly the same thickness so they cook evenly; about 150 grams each is perfect for a main course portion.
• Olive oil: Use something you'd actually taste on bread—extra virgin makes a real difference here.
• Fresh lemon juice and zest: This isn't the time for the bottled stuff; the brightness comes from real lemon, and the zest adds complexity you can't fake.
• Sea salt and black pepper: Coarse salt and freshly ground pepper taste sharper and more alive than pre-ground.
• Capers: Always rinse them first to cut down the brine, unless you want something aggressively salty.
• Shallot: Minced finely, it melts into the fish and adds sweetness without overpowering.
• Fresh parsley: The green stuff at the end is what makes people think you've done something complicated.
• Lemon slices: Thin ones let the heat pass through; thick ones just sit on top like garnish.

Instructions

Get your setup ready:

Preheat the oven to 200°C and line a baking dish with parchment paper or a light coat of olive oil. This takes ninety seconds and saves you from scraping fish off the bottom later.

Dry the fish properly:

Pat the cod fillets completely dry with paper towels and arrange them in the dish. Wet fish steams instead of roasts, so this step actually matters.

Make the marinade:

Whisk together olive oil, lemon juice, lemon zest, salt, and pepper in a small bowl until combined. Brush it evenly over each fillet, getting into the little crevices.

Add the toppings:

Scatter minced shallot and rinsed capers over the fish, then place one lemon slice on top of each piece. It'll look simple on the pan; trust that it's enough.

Bake with patience:

Slide it into the oven for eighteen to twenty minutes—you're looking for the moment when the fish flakes easily with a fork and the flesh turns completely opaque. It happens fast, so don't wander off.

Finish and serve:

Pull it from the oven, sprinkle fresh parsley over everything, and get it to the table while it's still warm. The whole thing works best right away.

The first time I served this to people I actually cared about impressing, I was shocked by how much it looked like something from a restaurant. They asked for the recipe thinking it must be complicated, and their faces when I told them it was basically four ingredients and twenty minutes—that's when I understood the power of simple, quality cooking done right.

What Makes This Work

The secret is in the restraint. There's no cream, no heavy sauce, no fussiness—just clean flavors that let the fish be itself. The briny capers and sharp lemon cut through any fishiness and make the whole thing feel Mediterranean and light. It's the kind of cooking that works because you're not trying too hard.

What to Serve It With

I've made this with steamed green beans, roasted potatoes, a crisp salad—it plays well with almost anything on the side. The real pairing magic happens if you can get your hands of a cold Sauvignon Blanc; the acidity in the wine echoes the lemon and capers and makes the whole meal feel intentional. Even just a crusty piece of bread to soak up any pan juices is enough.

Storage and Substitutions

Leftovers keep for two days in the fridge, though it's honestly better fresh. If cod isn't available or you want to mix things up, haddock or halibut swap in seamlessly—same cooking time, same magic. Dairy-free is already built in, so serve it to anyone without guilt.

• You can prep everything up to the point of baking several hours ahead; just cover and refrigerate until you're ready to cook.
• If your fillets are thicker than an inch, add a few extra minutes to the cooking time but keep checking.
• Make this meal feel fancier by plating the fish on top of the vegetables instead of beside them.

This is the kind of recipe that reminds you why cooking at home matters. It's fast enough for a Tuesday, elegant enough for guests, and honest enough that it tastes like something you actually made.
