Ingredients
For the Blackened Cod
4 cod fillets, about 5–6 oz (140–170 g) each
1 tablespoon olive oil
1 teaspoon smoked paprika
½ teaspoon garlic powder
½ teaspoon onion powder
½ teaspoon dried thyme
¼ teaspoon cayenne pepper, or to taste
½ teaspoon salt
¼ teaspoon black pepper
For the Creamy Lemon Herb Butter Sauce
3 tablespoons unsalted butter
3 garlic cloves, minced
½ cup heavy cream
2 tablespoons fresh lemon juice
1 teaspoon lemon zest
2 tablespoons chopped fresh parsley
1 tablespoon chopped fresh dill, optional
2 tablespoons grated Parmesan, optional
Salt and black pepper, to taste
Instructions
Step 1: Prepare the Cod
Pat the cod fillets dry with paper towels. In a small bowl, mix the smoked paprika, garlic powder, onion powder, thyme, cayenne, salt, and black pepper.
Brush the fish lightly with olive oil, then sprinkle the seasoning evenly over both sides.
Step 2: Sear the Fish
Heat a large skillet over medium-high heat. Add a small drizzle of oil if needed. Place the cod fillets in the skillet and cook for approximately 3–4 minutes per side, depending on thickness.
Handle the fish gently to prevent it from breaking. Cook until the center reaches 145°F (63°C) and the flesh is opaque and flakes easily. Transfer to a plate.
Step 3: Prepare the Garlic Butter Base
Reduce the heat to medium-low. Add the butter to the same skillet. Once melted, stir in the minced garlic and cook for about 30–60 seconds, until fragrant. Avoid browning the garlic.
Step 4: Make the Creamy Lemon Sauce
Pour in the heavy cream and stir, scraping up any flavorful browned bits from the pan. Simmer gently for 2–3 minutes until the sauce begins to thicken.
Stir in the lemon juice, lemon zest, parsley, and optional dill. Add Parmesan if desired. Season with salt and black pepper to taste. Avoid boiling the sauce vigorously, as it may separate.
Step 5: Bring Everything Together
Return the cooked cod to the skillet and spoon the creamy lemon herb butter sauce over the fillets. Let everything warm together for about 1 minute, then remove from the heat.
Step 6: Garnish and Serve
Finish with extra chopped parsley, a little lemon zest, and fresh lemon wedges. Serve immediately while the fish is tender and the sauce is warm.
Tips for the Best Blackened Cod
Dry the fish thoroughly: This helps the seasoning form a better crust.
Choose evenly sized fillets: Similar thickness helps the fish cook at the same rate.
Control the heat: Blackened seasoning can burn if the skillet is excessively hot, especially because paprika and garlic powder are involved.
Don’t overcook the cod: Check the thickest part with a food thermometer.
Keep the sauce at a gentle simmer: High heat can cause cream-based sauces to separate.
Easy Variations
Spicy blackened cod: Increase the cayenne or add a pinch of chili flakes.
Lighter lemon sauce: Replace half the cream with low-sodium chicken or vegetable broth for a thinner, less rich sauce.
Extra garlicky: Add one additional garlic clove to the butter.
Mediterranean twist: Add chopped spinach, halved cherry tomatoes, and a few sliced olives to the sauce.
Dairy-free option: Use a suitable dairy-free butter and unsweetened cooking cream alternative.
What to Serve with Blackened Cod
This dish pairs beautifully with roasted asparagus, garlic green beans, steamed broccoli, mashed potatoes, rice pilaf, or cauliflower rice. A crisp cucumber salad or lemon-dressed green salad also balances the creamy sauce nicely.
For a complete dinner, serve each fillet over rice or mashed potatoes and spoon the lemon herb butter sauce over the top.
Make-Ahead and Storage
You can mix the blackened seasoning up to several weeks ahead and store it in an airtight container in a cool, dry place. The lemon herb sauce is best prepared fresh, just before serving.
Store leftover cod and sauce in an airtight container in the refrigerator for up to 3 days. Reheat gently in a covered skillet over low heat until hot throughout, adding a splash of cream or broth if the sauce becomes too thick. Avoid repeated reheating, as cod can dry out.

Frequently Asked Questions
1. Can I use frozen cod for this recipe?
Yes. Thaw it completely in the refrigerator and pat it dry before seasoning. Removing excess moisture helps the fish sear instead of steam.
2. How do I keep cod from falling apart?
Use a wide spatula, avoid moving the fillets too often, and turn them gently once the first side has developed a crust.
3. Can I make the creamy lemon herb sauce without heavy cream?
Yes. You can use half-and-half for a lighter sauce, although it will be thinner and more prone to separating. Keep the heat low and avoid boiling.
4. Is blackened cod very spicy?
It depends on the amount of cayenne pepper. Start with a small pinch for mild heat, or leave it out entirely if you prefer a smoky flavor without much spice.
