Lemon Garlic Baked Cod

The first time I made this cod was on a rainy Tuesday when I needed something bright to cut through the gloom. That lemon garlic butter sauce filled my entire kitchen with the most incredible aroma, and my roommate actually came out of her room asking what I was making. Now whenever I see fresh cod at the market, I grab it immediately because I know dinner will be ready in under 30 minutes.

I served this at a small dinner party last month and watched my friend who never cooks take three photos of her plate before taking a single bite. The way the buttery garlic sauce clings to each flaky piece of fish makes it feel fancy without any actual fuss. My husband now requests this every time he has had a particularly long day at work.

Ingredients

• Cod fillets: Choose pieces that look opaque and firm to the touch, avoid any that look chalky or are falling apart
• Salt and black pepper: The only seasoning on the fish itself, so be generous and use freshly ground pepper
• Unsalted butter: Melted before mixing gives you better control over the final seasoning
• Extra virgin olive oil: Prevents the butter from burning in the high oven heat
• Fresh garlic: Dont use jarred minced garlic here, fresh makes such a difference in the sauce
• Fresh parsley: Adds beautiful color and a fresh bite that balances the rich butter
• Lemon zest and juice: Both are essential for that bright Mediterranean flavor profile
• Red pepper flakes: Just a whisper of heat that makes everything else pop

Instructions

Get your oven ready:

Preheat to 400 degrees Fahrenheit and grab a baking dish that will fit all your fillets in one cozy layer

Prep the cod:

Pat those fillets completely dry with paper towels, then season both sides thoroughly with your salt and pepper

Make the magic sauce:

Whisk together your melted butter, olive oil, garlic, parsley, lemon zest, lemon juice, and red pepper flakes until everything is emulsified and fragrant

Assemble it all:

Lay the cod in your prepared dish and pour that gorgeous lemon garlic butter evenly over every single fillet

Bake until perfect:

Let it cook for 12 to 15 minutes until the fish flakes apart easily when you gently test it with a fork and looks opaque throughout

Add the finishing touches:

Sprinkle with a little more fresh parsley and serve immediately with those lemon wedges on the side

Save

This recipe has saved me so many times when unexpected guests have dropped by or I completely forgot to plan dinner. My sister who lives across the country texts me whenever she makes it because it reminds her of home.

Choosing the Best Fish

I learned from a fishmonger that cod should smell like the ocean, not fishy at all. If it smells off, trust your nose and walk away. The flesh should bounce back when you press it gently.

Making It Ahead

You can mix up the lemon garlic butter sauce up to a day in advance and keep it in the fridge. Just bring it to room temperature before pouring over the fish so it coats evenly.

Perfect Side Dishes

Roasted asparagus with parmesan cooks at the same temperature and you can slide both dishes into the oven together. I also love serving this over cauliflower rice for a light but complete meal.

• A simple green salad with vinaigrette cuts through the butter perfectly
• Garlic roasted potatoes turn this into something more substantial
• Crusty bread is absolutely mandatory for soaking up every drop of sauce

Save

There is something deeply satisfying about a healthy dinner that tastes this indulgent. I hope this becomes your go-to for busy weeknights too.

Common Recipe Questions

→ What temperature should cod be baked at?

Bake cod at 400°F (200°C) for 12-15 minutes, or until the fish flakes easily with a fork and appears opaque throughout.

→ Can I substitute cod with other fish?

Yes, haddock, pollock, or halibut work well as substitutes. Adjust cooking time slightly depending on fillet thickness.

→ How do I know when the cod is done?

The cod is done when it flakes easily with a fork and the flesh is completely opaque. The internal temperature should reach 145°F.

→ Can I make this dairy-free?

Substitute the butter with additional olive oil or a dairy-free alternative. The flavor profile will remain bright and citrus-forward.

→ What sides pair well with this dish?

Steamed vegetables, rice pilaf, roasted potatoes, or crusty bread complement the lemon-garlic flavors beautifully. A light green salad works well too.
