Ingredients

For the Cod

2 tablespoons unsalted butter, melted
1 tablespoon extra-virgin olive oil
4 cloves garlic, minced
1 teaspoon paprika
½ teaspoon dried Italian seasoning
½ teaspoon salt
½ teaspoon freshly ground black pepper
1 tablespoon fresh lemon juice
1 teaspoon lemon zest
1 tablespoon chopped fresh parsley

For the Creamy Garlic Butter Sauce

2 tablespoons unsalted butter
4 cloves garlic, minced
¾ cup heavy cream
½ cup chicken or vegetable broth
¼ cup freshly grated Parmesan cheese
1 teaspoon Dijon mustard
½ teaspoon Italian seasoning
¼ teaspoon black pepper
1 tablespoon fresh lemon juice
1 tablespoon chopped fresh parsley

Optional Garnishes

Fresh parsley
Lemon wedges
Extra Parmesan
Cracked black pepper
Red pepper flakes
Fresh dill
Lemon zest

Instructions

1. Preheat the Oven

Preheat your oven to 400°F (200°C).

Lightly grease a medium-sized baking dish with butter or olive oil.

Pat the cod fillets thoroughly dry using paper towels.

Drying the fish is important because excess moisture can prevent the seasonings from sticking and can cause the fish to release too much liquid while baking.

Arrange the cod fillets in the prepared baking dish, leaving a little space between each piece.

2. Season the Cod

In a small bowl, combine melted butter, olive oil, minced garlic, paprika, Italian seasoning, salt, black pepper, lemon juice, and lemon zest.

Mix well.

Brush the garlic-butter mixture generously over the top of each cod fillet.

Make sure the garlic is distributed evenly.

Allow the fish to sit for about 5 minutes while you prepare the sauce.

3. Prepare the Creamy Garlic Butter Sauce

Melt 2 tablespoons butter in a small saucepan over medium-low heat.

Add the minced garlic and cook for approximately 30–60 seconds, stirring constantly.

The garlic should become fragrant but should not brown.

Add the heavy cream and broth.

Whisk gently to combine.

Add Dijon mustard, Italian seasoning, and black pepper.

Bring the sauce to a very gentle simmer.

Cook for approximately 2–3 minutes, stirring occasionally.

Do not allow the cream to boil aggressively.

4. Add Parmesan

Reduce the heat to low.

Gradually stir in the freshly grated Parmesan cheese.

Continue stirring until the cheese melts and the sauce becomes smooth.

Add 1 tablespoon fresh lemon juice.

Taste the sauce.

If necessary, add a small pinch of salt.

Remember that Parmesan already contains salt, so taste before adding more.

5. Add the Sauce to the Baking Dish

Pour the creamy garlic butter sauce around and partially over the cod fillets.

Avoid completely covering the fish if you want the seasoned surface to remain visible.

Sprinkle fresh parsley over the top.

If desired, add a small pinch of red pepper flakes for gentle heat.

6. Bake the Cod

Place the baking dish in the preheated oven.

Bake for approximately 18–22 minutes, depending on the thickness of the fillets.

Cod is ready when it becomes opaque and flakes easily with a fork.

For food safety, fish should reach an internal temperature of 145°F (63°C).

Avoid overcooking because cod can become dry when cooked too long.

Very thick fillets may require a few additional minutes, while thinner fillets may cook more quickly.

7. Finish and Serve

Remove the baking dish from the oven.

Allow the cod to rest for approximately 3–5 minutes.

Spoon some of the creamy garlic butter sauce over each fillet.

Garnish with fresh parsley, lemon zest, cracked black pepper, and lemon wedges.

Serve immediately.

Notes

Choosing Cod

Fresh cod is ideal, but high-quality frozen cod can also work beautifully.

If using frozen cod, thaw it completely in the refrigerator and pat it very dry before cooking.

Cod Thickness

Cooking time depends more on thickness than weight.

Thin fillets can cook in 12–15 minutes, while thick center-cut pieces may require closer to 20–25 minutes.

Don’t Overcook

Cod is naturally lean, so overcooking can quickly make it dry.

Start checking the fish toward the lower end of the recommended cooking time.

Garlic

Fresh garlic provides the best flavor.

Avoid burning the garlic because it can become bitter.

Parmesan

Freshly grated Parmesan melts better than pre-shredded cheese and produces a smoother sauce.

Cream

Heavy cream creates the richest sauce.

For a lighter sauce, half-and-half can be substituted, although the sauce may be slightly thinner.

Tips for the Best Creamy Garlic Butter Baked Cod

1. Pat the Fish Dry

This simple step helps the seasoning adhere and improves the final texture.

2. Use Fresh Lemon

Fresh lemon juice provides a brighter flavor than bottled juice.

3. Don’t Boil the Cream

A gentle simmer is enough. Vigorous boiling can cause the sauce to separate.

4. Use a Properly Sized Baking Dish

A dish that’s too large can cause the sauce to spread too thinly. A moderately sized baking dish helps keep the cod surrounded by sauce.

5. Check the Fish Early

Cod cooks quickly.

Start checking thinner fillets after approximately 12–15 minutes.

6. Let the Fish Rest

A few minutes of resting allows the juices to settle and gives the sauce time to slightly thicken.

7. Finish With Lemon

A final squeeze of lemon cuts through the richness of the cream and butter and makes the dish taste fresher.

How to Make It Spicy

For a spicy version, add:

½ teaspoon red pepper flakes
¼ teaspoon cayenne pepper
1 teaspoon hot sauce
A pinch of chili powder

You can add the spice directly to the garlic-butter seasoning or the cream sauce.

For a milder family-friendly version, leave out the red pepper flakes.

How to Make It Lighter

If you want a lighter version, make a few simple substitutions.

Use:

1 tablespoon butter instead of 2 in the sauce
Half-and-half instead of heavy cream
Reduced-fat Parmesan
Extra broth
More lemon juice and herbs

You can also serve the cod with steamed vegetables instead of mashed potatoes or pasta.

Keep in mind that changing the ingredients will change the nutritional information.

Dairy-Free Version

To make the recipe dairy-free, replace the butter with olive oil or a dairy-free butter alternative.

Use an unsweetened dairy-free cooking cream or cashew cream instead of heavy cream.

Omit Parmesan or use a dairy-free Parmesan alternative.

The result will still have a delicious garlic and herb flavor.

Mediterranean-Style Variation

For a Mediterranean twist, add:

Cherry tomatoes
Spinach
Kalamata olives
Artichoke hearts
Fresh oregano
Crumbled feta

Add cherry tomatoes and olives to the baking dish before placing the cod inside.

The combination of lemon, garlic, olive oil, tomatoes, and herbs works especially well with white fish.

Vegetable Additions

You can turn this into a complete one-pan meal by adding vegetables around the fish.

Good choices include:

Asparagus
Broccoli
Spinach
Zucchini
Cherry tomatoes
Bell peppers
Green beans
Mushrooms

For vegetables that require longer cooking, roast them for 10–15 minutes before adding the cod.

Serving Suggestions

Roasted Potatoes

Crispy roasted potatoes are excellent with the creamy sauce.

Mashed Potatoes

Mashed potatoes absorb the garlic butter sauce beautifully.

Rice

Serve the cod and sauce over white rice, brown rice, or basmati rice.

Pasta

Toss cooked pasta with some of the sauce and serve the cod on top.

Steamed Vegetables

Broccoli, green beans, asparagus, and zucchini provide a fresh contrast to the rich sauce.

Crusty Bread

A slice of crusty bread is perfect for dipping into the remaining creamy garlic sauce.

Fresh Salad

A simple lemon-dressed green salad helps balance the richness of the dish.

Make-Ahead Instructions

You can prepare the seasoning and sauce several hours ahead.

Keep the sauce refrigerated in an airtight container.

When ready to cook, gently warm the sauce before pouring it around the cod.

For the best texture, don’t fully bake the fish hours ahead and then reheat it. Cod is best served shortly after cooking.

Storage

Store leftover cod and sauce in an airtight container in the refrigerator.

Consume within 2–3 days.

Reheat gently in a covered skillet over low heat or in the oven at approximately 300°F (150°C).

Avoid overheating because the cod can become dry and the cream sauce can separate.

Add a small splash of broth or cream while reheating if the sauce has thickened considerably.

Can You Freeze It?

The baked cod itself can be frozen, but the creamy sauce may change texture slightly after freezing and thawing.

For the best result, enjoy the dish fresh.

If freezing is necessary, cool the fish completely, place it in a freezer-safe container, and freeze for up to approximately 1 month for best quality.

Thaw in the refrigerator and reheat gently.

Servings

This recipe makes approximately 4 servings.

Each serving includes one cod fillet with a generous amount of creamy garlic butter sauce.

For a larger gathering, simply increase the ingredients while making sure not to overcrowd the baking dish.

If cooking 6–8 fillets, use a larger baking dish or two dishes so the fish cooks evenly.
