Garlic Butter Cod Skillet

wafaawjjamal

• Prep time: 5 minutes
• Cook time: 15 minutes
• Total time: 20 minutes

• Serves: 4

Ingredients

For the cod:

• 4 cod fillets, about 5 to 6 ounces each
• 1 tablespoon olive oil
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper
• 1/2 teaspoon paprika

For the garlic butter sauce:

• 3 tablespoons unsalted butter
• 4 cloves garlic, minced
• 2 tablespoons fresh lemon juice
• 1 teaspoon lemon zest
• 1 tablespoon chopped fresh parsley
• 1/4 teaspoon red pepper flakes, optional

For serving:

• Lemon wedges
• Extra chopped parsley

Instructions

• 1)

  Make sure to carefully follow each step of the instructions for the best results :

  • Season the cod.
    Pat the cod fillets dry with paper towels, then season both sides with salt, black pepper, and paprika. Drying the fish first helps it sear better and keeps the surface from turning watery in the pan.
  • Sear the fish.
    Heat the olive oil in a large skillet over medium heat. Add the cod fillets and cook for 3 to 4 minutes on the first side, depending on thickness, until lightly golden. Carefully flip and cook for another 2 to 3 minutes, just until the fish is nearly cooked through. Transfer the cod to a plate.
  • Make the garlic butter.
    Lower the heat slightly and add the butter to the same skillet. Once melted, stir in the garlic and cook for about 30 seconds until fragrant. Add the lemon juice, lemon zest, parsley, and red pepper flakes if using. Stir gently and let the sauce bubble for just a few seconds.
  • Finish the cod.
    Return the cod to the skillet and spoon the garlic butter sauce over the top. Let it cook for another 1 to 2 minutes until the fish flakes easily with a fork and is fully cooked through.
  • Serve warm.
    Remove from the heat and serve right away with lemon wedges and a little extra parsley on top. Spoon the pan sauce over each fillet before serving for the best flavor.

Tips for the Best Garlic Butter Cod Skillet

• Pat the cod dry before cooking so it sears instead of steaming
• Use medium heat, not high, so the fish cooks gently and stays tender
• Flip the cod carefully with a thin spatula since it becomes delicate as it cooks
• Don’t overcook it, or the fish can turn dry and fall apart
• Fresh lemon juice gives the sauce a brighter flavor than bottled juice
• Add the garlic after the fish is seared so it doesn’t burn
• If your fillets are very thin, reduce the cooking time slightly

Variations

• Lemon herb version. Add dill or thyme along with the parsley for a fresher finish.
• Spicy version. Increase the red pepper flakes for a little more heat.
• Mediterranean version. Add cherry tomatoes and spinach to the skillet for extra color and flavor.
• Creamy version. Stir in a splash of heavy cream at the end for a richer sauce.
• Halibut version. Use halibut or another firm white fish if cod isn’t available.

Can I Use Frozen Cod Instead?

Yes, absolutely. Just thaw it fully first and pat it very dry before seasoning. If the fish holds too much moisture, it won’t sear as well and the sauce can turn a little watery. Once thawed properly, frozen cod works very well in this recipe.

What to Serve with Garlic Butter Cod Skillet

This light low carb dinner pairs well with simple sides that let the fish stay the star:

• Roasted asparagus
• Sautéed green beans
• Cauliflower rice
• Garlic spinach
• A crisp green salad
• Roasted zucchini

Storage & Reheating

Store leftover cod in an airtight container in the refrigerator for up to 2 days. Fish is always best fresh, but this one reheats well enough for a quick next-day lunch.

To reheat, warm it gently in a skillet over low heat with a spoonful of the sauce, or microwave in short intervals at reduced power. Be careful not to overheat it, or the cod can dry out quickly.

FAQ

Is cod a good fish for skillet cooking?

Yes. Cod is mild, flaky, and cooks quickly, which makes it a great choice for a fast skillet dinner.

Can I make this dairy-free?

Yes. Replace the butter with olive oil or a dairy-free butter alternative for a similar result.

How do I know when cod is done?

The fish should turn opaque and flake easily with a fork. It should look moist and tender, not dry.

Can I add vegetables to the same skillet?

Yes. Spinach, cherry tomatoes, or zucchini work especially well and cook quickly enough to fit into the recipe.

Is this recipe good for meal prep?

It’s better for short-term leftovers than full meal prep, since fish tastes best freshly cooked, but it does work for next-day lunches.
