Why Each Ingredient Matters
Alaskan cod: Cod has a naturally mild flavor and large, flaky pieces, so it works beautifully with simple seasonings. Its lean texture also cooks quickly.
Olive oil: Adds moisture and helps the seasonings cling to the fish while encouraging light browning.
Butter: Butter gives the cod a richer, more rounded flavor. Combining it with olive oil also helps create a flavorful coating without relying entirely on butter.
Garlic: Fresh garlic brings savory depth and becomes slightly sweet and mellow as it bakes.
Lemon juice and zest: Lemon balances the richness of butter and olive oil. The zest adds concentrated citrus aroma without making the fish overly acidic.
Paprika: A small amount adds warm color and mild earthy sweetness.
Italian seasoning: Dried herbs provide a quick layer of flavor without requiring several fresh herbs.
Salt and pepper: These aren’t just seasonings—they help bring out the natural flavor of the cod.
Fresh parsley: Added at the end, parsley gives the finished dish a fresh, bright contrast.
Step-by-Step Instructions
Step 1: Prepare the Oven and Cod
Preheat your oven to 400°F (200°C).
Pat the cod fillets dry with paper towels. This small step matters because excess moisture can make the fish steam instead of developing a lightly golden surface.
Place the fillets in a lightly greased baking dish or on a parchment-lined sheet pan.
If your cod has unevenly thick portions, tuck the thinner ends underneath slightly so the pieces cook more evenly.
Step 2: Make the Garlic-Lemon Seasoning
In a small bowl, combine:
- 1 tablespoon olive oil
- 1 tablespoon melted butter
- 2 minced garlic cloves
- 1 tablespoon lemon juice
- 1 teaspoon lemon zest
- 1 teaspoon paprika
- ½ teaspoon Italian seasoning
- ½ teaspoon kosher salt
- ¼ teaspoon black pepper
Stir until everything is well combined.
Don’t worry if the mixture looks a little separated. The oil and butter don’t need to form a perfect emulsion for this recipe.
Step 3: Season the Cod
Brush the garlic-lemon mixture generously over the top of each cod fillet.
Try to coat the fish evenly, especially the thicker center portions.
For extra flavor, let the seasoned fish sit at room temperature for 5–10 minutes while the oven finishes heating. Don’t leave raw fish sitting out for an extended period.
Step 4: Bake Until Flaky
Place the cod in the preheated oven.
Bake for approximately 12–15 minutes, depending on the thickness of the fillets.
The fish should look opaque and should separate easily into large flakes when gently tested with a fork.
For the most reliable result, use an instant-read thermometer. Fish should reach 145°F (63°C) in the thickest part for food safety.
Chef’s tip: Cod can go from perfectly tender to dry surprisingly quickly. Start checking thinner fillets around the 10–12 minute mark.
Step 5: Add Fresh Flavor
Remove the baked cod from the oven and let it rest for 2–3 minutes.
Spoon some of the buttery juices from the baking dish over the fish.
Sprinkle with freshly chopped parsley and add a squeeze of fresh lemon juice.
That final hit of lemon makes a noticeable difference. It wakes up the mild fish and keeps the dish from tasting heavy.
Step 6: Serve Immediately
Transfer the cod to serving plates and garnish with additional lemon wedges and parsley.
Serve while hot with your favorite sides.
Great pairings include:
- Roasted asparagus
- Steamed broccoli
- Green beans
- Rice pilaf
- Mashed potatoes
- Roasted baby potatoes
- Couscous
- Simple garden salad
Food safety note: Don’t rely only on appearance when cooking fish. A food thermometer is the safest way to confirm that the center has reached 145°F (63°C).
Health Benefits
Alaskan cod is a naturally lean source of protein, making it a useful choice for a balanced dinner.
Protein-rich
A serving provides a substantial amount of high-quality protein, which supports muscle maintenance and helps keep you feeling satisfied after a meal.
Naturally low in carbohydrates
The cod itself contains virtually no carbohydrates, making this recipe easy to pair with vegetables or other carbohydrate choices depending on your dietary needs.
Provides important nutrients
Cod provides nutrients including vitamin B12, selenium, phosphorus, and niacin.
Light but satisfying
Because cod is lean and the recipe uses a modest amount of butter and olive oil, the finished meal can feel satisfying without being overly heavy.
Nutrition can vary depending on the exact size of the fillets, brands of ingredients, and amount of butter or oil used.

Pro Tips & Variations
For perfectly flaky cod
Pat the fish dry first. Moisture on the surface can interfere with browning and seasoning.
Don’t overbake it. Cod is lean, so a few extra minutes can make the texture noticeably drier.
Use similarly sized fillets. If one piece is much thinner than another, it will finish sooner.
Check the thickest part. If you’re using a thermometer, insert it horizontally into the thickest section of the fish.
Add lemon after baking, too. Fresh lemon juice at the table tastes brighter than relying entirely on lemon juice added before cooking.
Easy variations
Garlic Parmesan Cod: Add 1–2 tablespoons grated Parmesan to the top during the final few minutes of baking.
Spicy Baked Cod: Add ¼–½ teaspoon red pepper flakes or a pinch of cayenne to the seasoning.
Mediterranean Cod: Add chopped cherry tomatoes, olives, oregano, and a little extra lemon before baking.
Herb Butter Cod: Replace the Italian seasoning with fresh dill, parsley, or chives.
Low-fat version: Reduce the butter and use slightly more olive oil. The cod will still be flavorful because garlic, herbs, and lemon do much of the heavy lifting.
Frozen cod: You can cook cod from frozen, but the cooking time will be longer and the texture may be slightly different. For the best result, thaw it completely in the refrigerator and pat it dry before seasoning.
How Much Does It Cost to Make?
The cost depends heavily on where you live and the price of cod, but this is still a fairly economical seafood dinner when compared with many restaurant options.
Approximate U.S. grocery-store cost for 4 servings:
| Ingredient | Estimated Cost |
|---|---|
| 4 cod fillets | $12–$18 |
| Olive oil | $0.40 |
| Butter | $0.30 |
| Garlic | $0.30 |
| Lemon | $0.75 |
| Herbs & spices | $0.50 |
| Parsley | $0.50 |
| Estimated Total | $14.75–$20.75 |
| Approx. Per Serving | $3.70–$5.20 |
Money-saving tip: Buy cod when it’s on sale and freeze individual portions. Since most of the other ingredients are pantry staples, the fish is usually the biggest part of the grocery bill.
