Lemon Herb Baked Cod is a bright and fresh dish that’s as simple as it is delicious. The flaky white fish is lightly seasoned with fragrant herbs and zesty lemon, then baked to tender perfection. It’s a dish that feels light but still full of flavor, perfect for a quick weeknight dinner or a laid-back weekend meal.
I love making this recipe because it comes together so easily and doesn’t require a long list of ingredients. I usually use whatever fresh herbs I have on hand—like parsley, thyme, or dill—and the lemon adds just the right amount of tang to keep things lively without overwhelming the natural flavor of the cod. It’s one of those dishes that always feels like a little celebration on the plate.
My favorite way to serve Lemon Herb Baked Cod is with a side of roasted vegetables or a simple green salad. Sometimes I like to add a scoop of rice or some crusty bread to soak up any lemony juices left on the plate. It’s a meal that feels wholesome and satisfying but still light enough to leave you feeling great afterward.
Key Ingredients & Substitutions
Cod Fillets: Cod is mild and flaky, perfect for baking. If you can’t find cod, try haddock or pollock for a similar texture and flavor.
Lemon: Fresh lemon slices give brightness and keep the fish moist. If lemons aren’t available, a splash of lemon juice works as a good substitute.
Olive Oil and Herbs: Olive oil adds richness, and the blend of oregano, thyme, and parsley brings fresh, earthy notes. Feel free to swap dried herbs with fresh ones, but use more fresh herbs since their flavor is milder.
Garlic: Fresh garlic shines here. If you prefer a milder taste, reduce the amount or use garlic powder.
Red Pepper Flakes: These are optional. Add them if you like a little heat, or skip for a gentle, herb-forward dish.
How Do I Make Sure the Cod Turns Out Moist and Flaky?
Baking cod can dry it out if you’re not careful. Follow these simple steps for tender fish every time:
- Pat the fillets dry before baking to help the herb mixture stick well.
- Layer lemon slices under and on top of the fish to add moisture and flavor while baking.
- Brush the olive oil and herb mixture generously on each fillet to keep it from drying out.
- Bake at 400°F for only 12-15 minutes. Overcooking will make it dry, so check when the fish flakes easily with a fork.
These steps keep your cod moist and full of bright, fresh flavors.
Equipment You’ll Need
- Baking dish or parchment-lined baking sheet – I recommend this so the fish cooks evenly and cleanup is easy.
- Small bowl – perfect for mixing the herb and olive oil marinade.
- Sharp knife – for slicing lemons and chopping parsley, making prep quick and safe.
- Measuring spoons – to ensure the herbs and spices are just right.
- Kitchen tongs or a spatula – for placing and removing the fish without breaking it apart.
Flavor Variations & Add-Ins
- Swap lemon for lime or orange slices for a different citrus twist—great for a fresh, fruity flavor.
- Add a pinch of smoked paprika or cayenne pepper for a smoky or spicy kick that pairs well with the herbs.
- Stir in chopped fresh basil or dill instead of parsley for a different herb note that brightens the dish.
- Top with sliced cherry tomatoes or olives before baking for added color and a salty, tangy flavor.

How Much Time Will You Need?
This recipe takes about 10 minutes to prepare and 12-15 minutes to bake, making it a quick and tasty meal you can enjoy in under 30 minutes.
Step-by-Step Instructions:
1. Prepare Your Oven and Baking Dish:
Preheat your oven to 400°F (200°C). Lightly grease a baking dish or line it with parchment paper for easy cleanup.
2. Mix the Herb and Olive Oil Blend:
In a small bowl, combine the olive oil, minced garlic, dried oregano, thyme, parsley, crushed red pepper flakes (if using), salt, and black pepper. Stir well to mix all the flavors together.
3. Layer Lemon Slices and Place the Cod:
Pat the cod fillets dry using paper towels to remove excess moisture. Place a few lemon slices evenly at the bottom of your baking dish. Then, lay the cod fillets on top of the lemon slices.
4. Brush and Top the Cod:
Brush each fillet generously with the herb and olive oil mixture, making sure to coat all sides. Place a lemon slice on top of each fillet to boost flavor and make the dish look nice.
5. Bake until Tender and Flaky:
Put the baking dish in your preheated oven and bake for 12-15 minutes. The fish is ready when it flakes easily with a fork and looks opaque all through.
6. Garnish and Serve:
Remove the cod from the oven, sprinkle chopped fresh parsley over the top, and serve immediately. You can add some extra lemon wedges on the side for more zest. This delicious dish pairs beautifully with steamed veggies, rice, or a light salad.
Can I Use Frozen Cod Fillets for This Recipe?
Yes! Just make sure to fully thaw the fillets in the refrigerator overnight or under cold running water before cooking. Pat them dry well to avoid excess moisture.
Can I Substitute Fresh Herbs for Dried?
Absolutely! Use about three times the amount of fresh herbs as dried since fresh herbs have a milder flavor. Add them toward the end of prepping to keep their brightness.
How Should I Store Leftovers?
Keep any leftovers in an airtight container in the fridge for up to 2 days. Reheat gently in the oven or microwave, covering loosely to retain moisture.
Can I Add Other Vegetables to Bake with the Cod?
Yes! Thinly sliced zucchini, cherry tomatoes, or bell peppers work great when placed around the fish before baking, adding flavor and a complete meal.
