Sea-Inspired Simplicity

This dish draws inspiration from coastal fishing villages where fish is simply seasoned with lemon and butter, highlighting its natural flavor.
The combination of lemon and butter has been a classic pairing in European seaside cuisines for centuries, especially in French and Mediterranean cooking.
Traditionally, cod was preserved through drying and salting, but fresh fillets like this became popular as markets expanded and refrigeration improved.

Ingredient breakdown: key components

Lemon: I squeeze fresh lemon juice over the fish for that zingy brightness, but you can swap in lime for a slightly different citrus kick.
Butter: I use unsalted butter to create a rich, velvety sauce that coats the cod; try ghee if you want a nuttier flavor.
Cod: I prefer fresh cod fillets because they’re tender and flaky, but frozen works well if thawed properly and patted dry first.
Garlic: I mince it finely to release more aroma and flavor, but whole cloves can be added for a subtler, roasted garlic note.
Olive oil: I use a splash for cooking, adding a fruity depth, but avocado oil can handle higher heat if needed.
Parsley: I sprinkle fresh chopped parsley at the end for freshness; basil or cilantro can add a different herbal note if you prefer.
Salt & pepper: I season generously, but taste as you go—too much salt can overpower the delicate lemon butter, so adjust accordingly.

Step-by-step guide to Lemon Butter Cod

Equipment & Tools: Get a non-stick or cast iron skillet, fish spatula, small saucepan, and a spoon for basting. Preheat your pan over medium heat (~160°C / 320°F).
Pat the cod fillets dry with paper towels—moisture is the enemy of a good sear. Season generously with salt and pepper on both sides.
Add a splash of olive oil to the hot skillet. When shimmering, gently lay the fillets skin-side down. Cook for about 3-4 minutes until the edges turn opaque and golden.
Carefully flip the fillets with a fish spatula. Cook for another 2-3 minutes. The fish should flake easily but still feel moist inside. If sticking occurs, lift gently and adjust heat slightly.
Meanwhile, in a small saucepan, melt 2 tbsp butter over low heat. Add 1-2 minced garlic cloves. Cook for 30 seconds until fragrant—avoid browning. Stir in 1 tbsp lemon juice and a pinch of salt.
Once the fish is nearly done, spoon the lemon butter over the fillets. Baste for 30 seconds to infuse flavor and keep the surface moist. The butter should shimmer and smell bright.
Remove the fillets from the pan. Let rest for 2 minutes—this helps the juices redistribute. Plate carefully, spooning extra lemon butter over the top, and sprinkle with chopped parsley.

Let the fish rest for 2 minutes to lock in juices. Plate carefully, spoon extra lemon butter over the top, and sprinkle with fresh parsley for a vibrant finish.

Ingredients Equipment Method

Ingredients

2 fillets cod fillets fresh or properly thawed if frozen
2 tbsp unsalted butter
1-2 cloves garlic minced finely
1 tbsp lemon juice freshly squeezed
1 lemon lemon for zest and garnish
1 tbsp olive oil for cooking
a handful parsley chopped, for garnish
to taste salt
to taste pepper

Equipment

Non-stick or cast iron skillet
Fish spatula
Small saucepan
Spoon

Method

Start by patting the cod fillets dry with paper towels and seasoning them generously with salt and pepper on both sides. This will help achieve a crispy exterior.
Heat a tablespoon of olive oil in your skillet over medium heat until shimmering and slightly fragrant. Carefully place the fillets skin-side down if they have skin, and cook for about 3-4 minutes until the edges turn opaque and golden brown.
Gently flip the fillets using a fish spatula and cook for another 2-3 minutes, until the fish flakes easily with a fork and remains moist inside. The surface should be golden and slightly caramelized.
Meanwhile, melt the butter in a small saucepan over low heat. Add the minced garlic and cook gently for about 30 seconds until fragrant but not browned, then stir in the lemon juice and a pinch of salt.
Once the fish is nearly cooked, spoon the lemon butter mixture over the fillets, basting them gently with a spoon for about 30 seconds. This infuses the fish with bright citrus flavor and keeps it moist.
Carefully transfer the fillets to a serving plate, then spoon any remaining lemon butter over the top. Grate a little lemon zest over for extra zing and sprinkle chopped parsley for freshness.
Let the fish rest for a minute or two, then serve immediately with your favorite sides, enjoying the tender, flaky texture and bright citrus flavors.

Common mistakes and how to fix them

FORGOT to dry the fish → Results in steaming, not searing. Pat dry thoroughly before cooking.
DUMPED lemon juice too early → Will lose brightness. Add lemon at the end for maximum zing.
OVER-TORCHED butter → Turns brown and bitter. Melt gently over low heat and watch carefully.
MISSED resting time → Fish becomes dry. Rest for 2 minutes before serving for juicier results.

Quick fixes and pantry swaps

If fish sticks to the pan, splash a little more oil and gently loosen with a spatula.
When the butter browns too quickly, patch with a splash of cold water to stop the burning.
Splash lemon juice at the end if sauce lacks brightness or to balance richness.
Dumped overcooked fish will be dry—rest it briefly and spoon extra lemon butter to moisten.
When the sauce shimmers without shine, rescue with a tiny pat of cold butter for gloss and flavor.

Prep, store, and reheat tips

Prep the lemon butter sauce ahead by melting butter and mixing in lemon juice; store in an airtight container in the fridge for up to 2 days. Reheat gently until just warm, noting it will shimmer and smell bright.
Pat the cod fillets dry and season ahead; keep covered in the fridge for up to 24 hours. Let sit at room temperature for 15 minutes before cooking to ensure even searing.
You can assemble the ingredients for the sauce and prepare the fillets in advance, but do not cook or season until ready to serve to preserve freshness and texture.
Store cooked fish in an airtight container in the fridge for up to 2 days. Reheat gently in a skillet over low heat, watching for bubbling and a citrus aroma to ensure it stays moist and flaky.
The lemon butter can be frozen for up to a month; reheat slowly in a saucepan. Expect the butter to separate slightly—give it a good stir and pay attention to the shimmer and citrus scent when reheated.
