I love how a simple fillet of cod can feel like a celebration on a weeknight table: glistening white flesh, fragrant garlic, bright lemon, and a silky butter sauce that pools around each piece like a warm embrace. This Baked Lemon-Garlic Cod with Butter Sauce is one of those recipes I turn to when I want something elegant that does not demand a lot of fuss.

Why You’ll Love This Little Weeknight Star

Bright, balanced flavor: lemon and garlic wake up the mild cod without overpowering it, so every bite is fresh and lively.
Comforting texture: the butter sauce keeps the fish tender and flaky while offering a rich, spoonable sauce for mopping up with bread.
Fast and forgiving: it bakes quickly and is hard to overcook if you watch for opaque flakiness, perfect for busy evenings.
Elegant but simple: it looks restaurant-worthy yet uses pantry-friendly ingredients.
Versatile pairing: it plays nicely with grains, greens, or roasted vegetables and even fits into a cozy date-night menu.

Ingredients You’ll Need

4 (6 oz) cod fillets — choose firm, fresh fillets for the cleanest flavor and best texture.
4 cloves garlic, minced — garlic provides aromatic depth and pairs beautifully with butter.
1/4 cup unsalted butter, melted — gives the sauce a silky mouthfeel; use unsalted so you can control seasoning.
2 tbsp fresh lemon juice — brightens and lifts the dish; freshly squeezed is worth the extra squeeze.
1 tsp lemon zest — adds concentrated lemon oil aroma for a floral pop.
1/4 tsp paprika — adds a whisper of color and gentle warmth without heat.
Salt and black pepper to taste — essential for seasoning and bringing out the flavors.
2 tbsp fresh parsley, chopped — a verdant finish that adds freshness and color.
Lemon slices for garnish — attractive and useful for guests who like an extra drizzle.

Let’s Get Cooking

I promise this is easier than it looks. Preheat your oven, gather your ingredients, and enjoy the quick rhythm of assembly.

Prepare the Crust:
1. Preheat your oven to 400°F (200°C). Line a baking dish with parchment or lightly grease it so the cod does not stick. Pat the fillets dry with paper towels to help the butter and seasonings cling.
2. In a small bowl, whisk together the melted butter, minced garlic, lemon juice, lemon zest, paprika, salt, and pepper until the mixture is cohesive and fragrant. The aroma of lemon and garlic should be immediate and uplifting.
3. Place the cod fillets in the prepared dish and spoon the garlic-butter mixture evenly over each piece, ensuring the tops and sides are coated. Scatter lemon slices around the fillets if you like an extra visual flourish.
4. Bake in the preheated oven for about 12 to 15 minutes, depending on thickness, until the fish is opaque and flakes easily with a fork. If you prefer a touch of char, broil for the final 1 to 2 minutes while watching closely.
5. Remove from oven and sprinkle the chopped parsley over the fillets. Let the fish rest for a minute so the juices settle, then serve with a spoonful of the butter sauce.

If you are curious about similar, quick-bake seafood preparations, I often compare timing and flavor profiles to a simple baked cajun salmon with creamy avocado lime sauce when deciding oven temperature and seasoning balance.

My Favorite Tricks for Reliable Results

Use room-temperature butter before melting so the sauce emulsifies more smoothly with lemon juice.
Pat the fillets very dry; moisture is the enemy of browning and will dilute your butter sauce.
Check for doneness visually rather than relying solely on time: cod should be opaque and flake at the thickest part.
If you want a nuttier finish, brown the butter slightly before mixing it with the garlic and lemon, but do not let it burn. For a flavor-forward tip, try the garlic treatment used with my garlic butter steak bites for inspiration about garlic timing and heat.

Mix It Up: Ways to Make It Your Own

Herb swap: replace parsley with dill or tarragon for a more anise-like lift.
Add capers or olives to the butter sauce for briny contrast that brightens the lemon.
Crust it: sprinkle panko mixed with grated Parmesan over the top for a crunchy finish.
Spicy kick: add a pinch of red pepper flakes or smoked paprika for warmth.
Serve it on a bed of roasted winter squash or creamy polenta for a comforting, seasonal twist, similar in comfort to my recipe for sweet potato gnocchi with brown butter sage sauce if you want a richer, cozier plate.

Bringing It to the Table

Present the fillets on a warm platter with spoonable pools of butter sauce glistening around them. Scatter extra parsley and a few thin lemon wedges for guests to squeeze. For sides, I love a crisp green salad with a lemony vinaigrette, roasted asparagus, or steamed baby potatoes tossed with a little extra butter and parsley. If you are entertaining, small sourdough toasts for dipping into the sauce make everyone feel happily indulgent.

Saving for Later

Refrigeration: Store cooled leftovers in an airtight container for up to 2 days. The sauce will thicken when cold; gently rewarm in a low oven or in a skillet with a splash of water or extra lemon juice.
Freezing: Cooked cod can be frozen, but texture will change; wrap tightly and freeze for up to 1 month. Thaw slowly in the fridge before reheating gently.
Reheating: Avoid the microwave if possible. Reheat on the stovetop in a skillet with a lid over low heat, adding a teaspoon or two of water or extra butter to revive the sauce and keep the fish moist.

Your Questions Answered

Q: Can I use other fish for this method?
A: Absolutely. Firm white fish like halibut, sea bass, or tilapia work well. Adjust cooking time for thickness.

Q: How do I know when cod is done?
A: The fillet should be opaque and flake easily with a fork at the thickest part. If you have a thermometer, aim for an internal temperature of about 135°F to 140°F for tender flakiness.

Q: Can I make the sauce ahead of time?
A: Yes. Make the garlic-butter sauce and refrigerate for up to 24 hours. Bring it to room temperature and whisk before spooning over the fish.

Q: What if I do not have fresh lemon?
A: Bottled lemon juice will work in a pinch, but you will miss the bright citrus oils from the zest. Add a touch more zest if you can source a frozen lemon rind or use a tiny splash of white wine to add brightness.
