Baked Cod Herbs Lemon Slices

There's something about cooking fish that strips away pretense. A few years ago, I was in a tiny kitchen in Lisbon, watching my friend Maria simply lay cod fillets on a plate with lemon and herbs, then slide them into the oven like it was the easiest thing in the world. I realized I'd been overthinking fish all along, drowning it in sauces and fussy techniques when what it really wanted was to be itself. This recipe is that moment distilled into 20 minutes.

My mom made this for a dinner party once, and I watched guests visibly relax as they took the first bite, forks moving slowly, conversations softening. No one asked for the recipe that night, which somehow felt right—like we were all just present with something simple and true. That's when I understood: the best recipes aren't the most complicated ones.

Ingredients

• Cod fillets (4, about 150 g each): Look for thick, opaque fillets that don't smell overly fishy; this is where the real magic happens, so don't skip quality here.
• Fresh parsley: The green backbone of this dish—use it generous and never dried.
• Fresh dill: Dill and fish are old friends; this one herb makes the difference between forgettable and memorable.
• Fresh chives: A whisper of onion that doesn't overpower, just lifts everything slightly.
• Garlic cloves (2), minced: Raw garlic scattered over fish might sound harsh, but it mellows beautifully as the fish steams.
• Lemon (1 large), thinly sliced: The lemon is both flavor and moisture here, so slice it thin and don't skip it.
• Extra-virgin olive oil (2 tablespoons): This becomes your sauce, so use oil you actually like tasting.
• Sea salt and black pepper: The salt brings out the sweetness in the fish; the pepper adds a quiet warmth.
• Capers (1 tablespoon), optional: If you have them, they add a briny little pop that some people live for.

Instructions

Get your oven ready:

Heat it to 200°C (400°F) and lightly grease a baking dish just large enough to hold your fillets in a single layer. This matters—too big and the heat scatters, too small and they steam unevenly.

Prepare the fish:

Pat your cod fillets completely dry with paper towels; any moisture on the surface keeps them from developing that delicate, subtle flavor. Place them gently in the baking dish.

Layer the flavor:

Drizzle the olive oil over the fillets, then scatter the salt, pepper, minced garlic, and all those fresh herbs across them like you're tucking them in for a short rest. The herbs will cook down, and their oils will infuse everything.

Tuck in the lemon:

Arrange your lemon slices over and around the fish, and scatter the capers on top if you're using them. The lemon will release juice as it roasts, creating a light pan sauce that catches all those herb flavors.

Bake gently:

Slide it into the oven for 18–20 minutes, watching until the cod is opaque and flakes easily when you test it with a fork. The exact time depends on how thick your fillets are, so keep an eye on it starting at 16 minutes.

Finish with care:

Serve it right away, spooning those pan juices over the fish to catch every bit of brightness and warmth you've created.

My daughter asked for seconds that one night, which never happens, and I realized it wasn't the complexity she loved—it was the simplicity. She could taste each ingredient, nothing fighting for space, everything in its right place. That's when food becomes more than sustenance; it becomes a small act of care.

Why This Works Every Time

Cod is forgiving in some ways and unforgiving in others. It's mild enough that you can't hide behind heavy sauces, but it's also sturdy enough to handle bright acidity and fresh herbs without getting bullied. The lemon does two things at once—it seasons and it creates moisture so the fish doesn't dry out. The herbs smell wonderful as they cook, and that aroma alone is worth the effort.

Making It Yours

Haddock or halibut swaps in beautifully if your market has them, sometimes even better depending on the season. I've done this with white wine splashed into the pan before baking, and it adds a subtle sweetness that pulls the whole thing together. Serve it with something simple—roasted potatoes, steamed vegetables, or just crusty bread to soak up the pan juices.

The Details That Matter

A sharp knife helps you slice the lemon thin enough to cook through without drying out. The baking dish should let you serve straight from it; something beautiful enough to bring to the table saves you a step and makes the moment feel more special than it deserves. Timing is everything here, so don't walk away from the oven—use those 18–20 minutes to set the table or pour a glass of something cold.

• Buy the best cod you can find; it's only five ingredients, so each one has to pull its weight.
• Fresh herbs are non-negotiable—they're what separates this from something forgettable.
• Serve it right away while the fish is still warm and the lemon is still bright.

This is the kind of recipe that makes you feel capable in the kitchen without asking for much in return. It's an act of generosity wrapped in simplicity.

Recipe Q&A

→ What temperature is best for baking cod?

Baking at 200°C (400°F) ensures the fish cooks evenly without drying out, keeping the texture tender and moist.

→ Can I use frozen fillets for this dish?

Yes, but thaw them completely and pat them dry before seasoning to ensure they bake properly and do not become watery.

→ How do I know when the fish is done?

The cod is ready when it becomes opaque and flakes easily with a fork. It should still feel moist rather than dry or fibrous.

→ What other fish work well here?

Haddock, halibut, or other mild white fish fillets are excellent substitutes that hold up well to the baking process.

→ What sides pair best with this?

Steamed vegetables, roasted potatoes, or a light bed of rice pair perfectly with the citrus and herb flavors.
