Baked Lemon Herb Cod

This baked lemon herb cod is a delightfully light and simple dish, perfect for those evenings when you want something fresh, healthy, and flavorful without spending too much time in the kitchen. Tender cod fillets gently bathed in a lemony garlic and herb marinade come together in under 30 minutes, making a naturally gluten—free and keto—friendly dinner that feels both nourishing and satisfying.

I made this for the first time during a hectic workweek and was amazed how comforting and special it felt with minimal effort. Now it’s a regular because it never fails to impress.

Ingredients

• Two fresh cod fillets: choose firm, white-fleshed cod for a mild, flaky texture
• Unsalted butter melted: adds richness and helps carry the herbs’ flavors
• Olive oil: use extra virgin for the best fruity aroma and Mediterranean flair
• Fresh lemon juice and zest: essential for bright citrus notes fresh is preferable over bottled for maximum zing
• Garlic cloves minced: fresh garlic infuses the dish with savory depth
• Salt and black pepper: fundamental seasonings that balance and enhance the flavors
• Dried oregano and thyme: classic Mediterranean herbs that complement fish well if using fresh, increase quantity by three times
• Crushed red pepper flakes: optional — for a mild heat kick if you like it spicy
• Fresh parsley chopped for garnish: adds a fresh, vivid touch and color

Instructions

Preheat Your Oven:

Set your oven to 400 degrees Fahrenheit or 200 degrees Celsius. Prepare a baking dish by lining it with parchment paper or lightly greasing it so the fish doesn’t stick.

Create the Lemon Herb Mix:

In a small bowl, whisk together the melted butter, olive oil, fresh lemon juice and zest, minced garlic, salt, black pepper, oregano, thyme, and red pepper flakes if you are using them. Mix thoroughly so the flavors marry.

Season the Cod Fillets:

Gently pat the cod fillets dry using paper towels to remove excess moisture, ensuring your lemon herb mixture clings well. Place the fillets in the prepared dish and evenly spoon the lemon herb marinade over them, coating the fillets well on all sides.

Bake to Perfection:

Place the baking dish into the preheated oven and bake for about 12 to 15 minutes. Check for doneness by inserting a fork or the tip of a sharp knife into the thickest part of the fillet. The fish should flake easily and look opaque (no translucency).

Garnish and Serve:

Remove the cod from the oven and sprinkle freshly chopped parsley generously on top. Serve immediately for the best flavor and texture.

This recipe is a family favorite partly because the lemon juice and herbs make the cod feel festive yet approachable. The brightness of fresh lemon zest is my favorite part I always make sure to zest right before prepping to capture the strongest flavor.

Storage Tips

Store leftover baked cod in an airtight container in the refrigerator for up to two days. Reheat gently in a low oven or covered skillet to avoid overcooking. Because the lemon and herbs are so fresh, the flavor may mellow a bit after storage, so a fresh squeeze of lemon before serving helps revive it.

Ingredient Substitutions

Halibut or haddock can stand in place of cod if you prefer a slightly different flaky white fish but want the texture and flavor profile to remain mild and fresh. For a vegan twist, firm tofu works surprisingly well. Marinate it in the lemon herb mixture and bake similarly. The tofu absorbs the flavors beautifully while providing a different but satisfying texture.

Serving Suggestions

Pair this cod with a bright green salad tossed in vinaigrette or roasted cherry tomatoes to keep the meal light and vibrant. Roasted fingerling potatoes or creamy Parmesan polenta add comfort and help balance the citrus notes beautifully. A crisp glass of white wine such as Sauvignon Blanc perfectly complements the fresh herbal and lemon flavors.

Simple, bright, and quick to make, this baked lemon herb cod is an easy weeknight winner. A squeeze of fresh lemon before serving revives the flavors.

Common Questions About the Recipe

→ How do I prevent overcooking the cod?

Keep a close watch as cod cooks quickly. Start checking doneness at 12 minutes; it's ready when opaque and flakes easily with a fork.

→ Can I use bottled lemon juice instead of fresh?

Fresh lemon juice delivers brighter, fresher flavors, but bottled juice can be used with minor flavor compromise.

→ What herbs work best for this dish?

Dried oregano and thyme add depth, but fresh herbs can be used in triple amounts for a vibrant, aromatic profile.

→ What are good side pairings for this fish?

Roasted cherry tomatoes, sautéed spinach, or lemon slices complement the cod nicely. Pairing with white wine or a fresh green salad elevates the meal.

→ Can I substitute the cod with other proteins?

Halibut or haddock offer similar mild textures. Firm tofu is a great vegetarian alternative that absorbs the lemon herb marinade well.
