Baked Cod with Herb Butter

My cousin brought home a batch of impossibly fresh cod from the market one afternoon, and I had about twenty minutes before dinner guests arrived. I melted some butter with whatever herbs I could find in the garden—dill, parsley, chives—added a squeeze of lemon, and suddenly the whole thing felt less like panic and more like possibility. That simple cod has been my go-to ever since, especially when I want something that tastes elegant without the stress.

I made this for my partner's birthday dinner years ago, and they described it as tasting like the seaside—which turned out to be the highest compliment in our house. We've made it dozens of times since, sometimes with crushed fennel pollen, sometimes with tarragon, but the principle never changes. It's become one of those dishes that signals I'm paying attention, that this meal matters.

Ingredients

• Cod fillets (4, about 150g each): Look for fillets that are bright white with no browning at the edges—that freshness makes all the difference in both flavor and texture.
• Unsalted butter (60g, softened): Cold butter won't blend smoothly with the herbs, so leave it on the counter while you prep everything else.
• Fresh parsley, dill, and chives: Don't skip the fresh herbs; they're what transform this from simple to special, and dried herbs turn bitter when mixed raw into butter.
• Garlic clove (1, minced): One clove is plenty—you want herb-forward flavor, not garlic dominating the plate.
• Lemon zest and juice: The zest gives brightness without extra liquid, and the juice keeps the butter from feeling heavy.
• Olive oil (1 tablespoon): Just enough to keep the fish from sticking; it's not a cooking oil here, just insurance.
• Salt and black pepper: Season the butter generously—the fish itself needs almost nothing because the herb butter does the work.

Instructions

Heat and prepare:

Turn your oven to 200°C and wipe a baking dish with olive oil—you want it slick enough that nothing sticks. This takes two minutes and saves you from frustration later.

Make the herb butter:

Combine your softened butter with the minced herbs, garlic, lemon zest, juice, salt, and pepper in a small bowl. Stir until everything is evenly distributed and the butter has turned pale green with flecks of herb throughout.

Prepare the fish:

Pat your cod fillets completely dry with paper towels—any moisture on the surface will steam instead of allowing the butter to coat properly. Arrange them in the baking dish with a little breathing room between each fillet.

Butter and bake:

Spread a generous spoonful of herb butter over each fillet, making sure it covers the top and some runs down the sides. Slide the dish into your preheated oven and bake for 15 to 18 minutes, watching until the fish turns opaque and flakes easily when you test it with a fork.

Serve immediately:

Transfer each fillet to a warm plate while the butter is still glossy, and squeeze a fresh lemon wedge over top just before eating.

The moment when someone takes their first bite and their eyes widen slightly—that's when I know this recipe is working. It's not complicated or fancy, but it tastes like you understand something about good food, which is maybe the best part of cooking for people who matter to you.

Choosing Your Fish

Cod is forgiving and mild, but haddock, halibut, and pollock work beautifully too if that's what looks fresh at your counter. The rule is: whiter fish, gentler flavor, and if it smells fishy rather than ocean-fresh, keep walking. Ask your fishmonger what came in that day and build your dinner around their recommendation instead of fighting what's available.

Building Flavor Beyond the Basics

Once you've made this a few times, you'll notice where you can play. A pinch of fennel pollen adds an almost licorice whisper, or swap half the parsley for tarragon if you're feeling delicate. A tiny grating of Parmesan over the top before baking adds richness without heaviness, and some people love a grind of smoked paprika mixed into the butter for depth. The herb butter is your canvas—respect the lemon and garlic foundation, but let your mood guide the rest.

Sides That Belong on the Plate

The herb butter is rich enough that you want something with brightness alongside it—roasted asparagus with a squeeze of lemon, steamed green beans with flaked almonds, or a crisp green salad tossed with Dijon vinaigrette all work perfectly. Roasted new potatoes are lovely too, especially if you toss them with fresh herbs to echo what's on the fish.

• Steamed vegetables let the cod shine without competing for attention.
• A simple salad with lemon vinaigrette balances the butter beautifully.
• If you want something warm and starchy, roasted potatoes or risotto won't overpower the delicate fish.

This is the kind of recipe that reminds you why cooking matters—it's fast, it's delicious, and it tastes like you know what you're doing. Keep it in your back pocket for nights when you want to feel accomplished without the stress.
