Lemon Garlic Butter Cod is a bright and tasty dish featuring tender cod fillets cooked in a buttery garlic sauce with a fresh squeeze of lemon. The combination of juicy fish and rich, zesty flavors makes it feel light yet satisfying. It’s simple but feels special enough for any night of the week.

I love how quick this recipe comes together—perfect for busy evenings when you want something delicious without spending hours in the kitchen. I usually add a little extra garlic because I’m a big fan, and the lemon adds just the right touch of brightness that keeps the butter from being too heavy. It always makes the whole kitchen smell amazing while it’s cooking.

My favorite way to serve this is with a side of steamed veggies or a fresh green salad. Sometimes I’ll even spoon the lemon garlic butter sauce over some rice or crusty bread to soak up every last bit. It’s a dish that feels like comfort food but still fresh and light—perfect for sharing with family or friends.

Key Ingredients & Substitutions

Cod fillets: Cod is mild and flaky, perfect for soaking up the lemon garlic butter sauce. If you can’t find cod, try haddock, halibut, or tilapia. These fish have a similar texture and mild flavor.

Butter and olive oil: Butter gives richness and flavor while olive oil helps prevent burning at higher heat. For dairy-free, swap butter with vegan margarine or use only olive oil.

Garlic: Fresh garlic is a must here for its bright aroma. Minced garlic adds a nice punch. If fresh isn’t available, use good quality garlic powder but use less, since it’s more intense.

Lemon: Lemon juice and slices add freshness and brightness that balance the butter. If fresh lemons aren’t handy, bottled lemon juice works, though fresh always tastes best.

Parsley: Chopped parsley adds a fresh herbal note and color. You can substitute with fresh cilantro or basil if you prefer, or omit if you don’t have herbs on hand.

How Can You Cook the Cod to Keep It Tender and Well-Seared?

Perfectly cooking cod means getting a golden crust while keeping the inside tender and flaky. Here’s how to do it:

  • Pat the fish dry with paper towels before seasoning. This helps the fish sear well without steaming.
  • Heat the oil over medium-high heat until shimmering but not smoking. This ensures a nice crust forms quickly.
  • Place the fillet skin-side down if it has skin, or presentation side down if skinless. Don’t move the fish for 3-4 minutes; this develops a golden crust and prevents sticking.
  • Flip gently using a thin, flexible spatula to keep the fillet intact.
  • Add butter and garlic right after flipping. Butter adds flavor and moisture; the garlic cooks quickly—watch it carefully to avoid burning.
  • Cook just until the fish flakes easily with a fork, about 3-4 minutes after flipping. Overcooking dries it out.

Following these steps will give you that perfect balance of a crispy, flavorful outside and soft, juicy inside every time.

Equipment You’ll Need

  • Large nonstick or stainless steel skillet – great for even cooking and easy fish flipping.
  • Tongs or fish spatula – helps you turn the delicate cod without breaking it.
  • Measuring spoons – for accurate butter, oil, and lemon juice amounts.
  • Knife and cutting board – to mince garlic and slice lemon thinly.
  • Plate and paper towels – to pat the fish dry for a nice sear.

Flavor Variations & Add-Ins

  • Swap cod for salmon or halibut – both firm fish that hold up well with garlic butter.
  • Add capers or chopped olives – introduces a briny touch that pairs well with lemon.
  • Mix fresh thyme or dill herbs instead of parsley for a different herbal note.
  • Include a pinch of red pepper flakes in the sauce for subtle heat.

Easy Lemon Garlic Butter Cod

How to Make Lemon Garlic Butter Cod

Ingredients You’ll Need:

For the Cod and Sauce:

  • 4 cod fillets (about 6 ounces each)
  • Salt and freshly ground black pepper, to taste
  • 2 tablespoons olive oil
  • 3 tablespoons unsalted butter, divided
  • 4 cloves garlic, minced
  • 1 lemon, thinly sliced, plus 2 tablespoons lemon juice
  • 2 tablespoons fresh parsley, finely chopped

Optional Sides:

  • Mashed potatoes
  • Sautéed green beans
  • Steamed vegetables

Time Needed

This dish takes about 10 minutes to prepare and 10 minutes to cook, totaling roughly 20 minutes. It’s quick, making it a perfect choice for a tasty weeknight meal.

Step-by-Step Instructions:

1. Prepare the Cod:

Pat the cod fillets dry with paper towels. Sprinkle both sides generously with salt and freshly ground black pepper to season.

2. Sear the Cod:

Heat olive oil in a large skillet over medium-high heat. When the oil is hot, carefully place the cod fillets in the pan. Cook without moving them for about 3-4 minutes, until the bottom is golden brown and crusty.

3. Flip and Add Butter:

Gently flip the fillets to the other side. Add 1 tablespoon of butter to the skillet, allowing it to melt.

4. Cook the Garlic and Lemon:

Add the minced garlic to the melted butter. Sauté for about 30 seconds until fragrant, being careful not to burn the garlic. Place the lemon slices around the fish and spoon some of the butter and garlic mixture over the top.

5. Finish Cooking the Cod:

Lower the heat to medium and cook for another 3-4 minutes, or until the fish flakes easily when tested with a fork.

6. Make the Sauce:

Remove the cod fillets and lemon slices to serving plates. To the hot skillet, add the remaining 2 tablespoons of butter and the lemon juice. Swirl the pan gently to create a smooth, delicious lemon garlic butter sauce.

7. Serve and Garnish:

Pour the sauce over the cod fillets. Sprinkle with fresh parsley for a bright, fresh finish. Serve immediately with your choice of sides like mashed potatoes or green vegetables.

Can I Use Frozen Cod for This Recipe?

Yes, you can! Just be sure to thaw the cod completely in the refrigerator overnight and pat it dry thoroughly before cooking to prevent excess moisture that can affect searing.

How Do I Store Leftover Lemon Garlic Butter Cod?

Store leftovers in an airtight container in the fridge for up to 2 days. Reheat gently in a skillet over low heat to keep the fish tender without drying it out.

What Can I Substitute If I Don’t Have Fresh Parsley?

You can use fresh cilantro, dill, or chives for a different but still fresh herbal note. If you don’t have fresh herbs, a sprinkle of dried parsley works in a pinch, but add it after cooking to retain flavor.

Can I Make This Dish Ahead of Time?

It’s best served fresh for the best texture and flavor, but you can prepare the sauce a day ahead and reheat gently with the fish just before serving.
