Baked Cod with Herb Butter

There's something about the simplicity of baked cod that caught me off guard the first time I made it properly. I was watching steam rise from the oven, hearing that gentle sizzle as herb butter began to melt into delicate white flakes, and suddenly understood why my grandmother kept coming back to white fish. It wasn't fancy or fussy—just butter, herbs, and the kind of restraint that lets the fish speak for itself. That moment changed how I cook when people are coming over.

My friend Sarah came over on a random Tuesday, stressed about work, and I threw this together while we talked. By the time the cod emerged golden and fragrant from the oven, she'd already forgotten why the day had felt impossible. That's when I realized this recipe wasn't just easy—it was kind, the sort of thing you make when you want someone to feel tended to without making it obvious.

Ingredients

• Cod fillets (150g each): Look for fillets that are similar in thickness so they cook evenly; pat them completely dry before seasoning or the skin gets soggy and the seasonings won't stick properly.
• Unsalted butter: Softened butter blends with herbs more smoothly than cold butter, and using unsalted lets you control the salt level yourself.
• Fresh parsley, dill, and chives: These three together create a balanced brightness—dill would overpower alone, parsley alone feels flat, but together they're alive on your tongue.
• Garlic clove: One clove is enough; more than that and it bullies the other flavors and can turn bitter in the oven heat.
• Lemon zest and juice: The zest carries aroma and oils that juice alone can't deliver; don't skip it even if you're in a hurry.
• Salt and pepper: Freshly ground pepper tastes sharper and more alive than pre-ground, and it matters more here since there aren't many ingredients competing.

Instructions

Get your oven ready and prepare the stage:

Preheat to 200°C (400°F) and line your baking dish with parchment paper—this keeps the fish from sticking and saves you from scrubbing later. A cold oven will cook the fish unevenly, so don't skip this step even if you're running late.

Dry and season the fish:

Pat each fillet dry with paper towels, then season both sides generously with salt and pepper. This step is quieter than you'd think—just the soft sound of the towel against the fish, but it's the difference between steamed fish and baked fish with actual character.

Make the herb butter:

Combine softened butter, finely chopped herbs, minced garlic, lemon zest, and lemon juice in a small bowl and stir until you have a bright green-flecked mixture that smells like a garden. Don't overthink the blending—a spoon and about 30 seconds is all you need.

Dress the fish:

Spread a generous spoonful of herb butter over the top of each fillet, letting it settle into the natural curves and edges. The herb butter will melt during cooking and flavor the whole fillet from above.

Bake until just cooked through:

Slide the dish into the oven for 12–15 minutes, depending on thickness; the fish is done when it flakes easily with a fork and has turned from translucent to opaque throughout. Set a timer so you don't forget—overcooked fish becomes dry and sad, but a minute or two under is always forgiving.

Serve while everything is warm:

Transfer to plates immediately, pour any pan juices over the top, and garnish with lemon wedges and extra herbs if you have them. This is a dish that loses something when it cools.

Pin it

The first time I got this right, my sister went quiet after her first bite—not the polite kind of quiet, but the kind where you know the food is speaking louder than words. That's when cooking stops being a chore and becomes a small act of generosity, something you do for the people across the table from you.

Why White Fish Works Here

Delicate fish like cod doesn't compete with bright flavors; it welcomes them. The herb butter isn't trying to mask anything or add richness to something bland—it's lifting what's already beautiful about the fish itself. Haddock, pollock, halibut, or sea bass work just as well, each bringing their own subtle sweetness to the same treatment. The key is choosing fish that are mild enough to let the herbs shine without overpowering.

Building Your Herb Butter

The magic of herb butter is that you can make it your own without breaking anything. Some days I'll add a tiny pinch of red chili flakes if I'm in the mood for warmth, other times tarragon instead of dill if that's what's fresh in my garden. The ratio of three parts butter to one part herbs keeps it balanced, but once you understand that, you can adjust to whatever you have on hand. I've made this with basil in summer, thyme in winter, and it's never disappointed.

Sides and Pairings

This dish doesn't demand much of what's beside it—actually, it prefers simple company. Steamed green beans let the fish stay center stage, roasted potatoes soak up the herb butter that pools on the plate, and a crisp green salad cuts through the richness just enough. The lemon wedges on the side aren't just garnish; squeeze them over everything before eating for a final bright note that ties it all together.

• Steamed vegetables with a touch of salt and butter are all the contrast you need.
• Make roasted potatoes in the same oven if you time it right, pulling the fish out five minutes before the potatoes are done.
• A simple arugula salad with lemon vinaigrette keeps the whole meal light and elegant.

Baked cod with herb butter taught me that elegance doesn't require complexity, just attention and fresh ingredients treated with respect. It's become the dish I reach for when I want to feed people well without the performance.
