Ingredients Method

Ingredients
  

  • 1.5 to 2 pounds cod fillets (about 4 pieces), fresh or thawed
  • 2 tablespoons olive oil
  • Zest of 1 lemon
  • Juice of 1 lemon (about 2–3 tablespoons)
  • 2–3 garlic cloves, minced
  • 1 teaspoon Dijon mustard (optional but adds depth)
  • 1 teaspoon kosher salt
  • 1/2 teaspoon black pepper
  • 1 teaspoon dried oregano
  • 1 teaspoon dried thyme or Italian seasoning
  • 2 tablespoons fresh parsley, chopped (plus more for garnish)
  • Lemon slices, for topping

Method
 

  1. Prep the oven and pan: Heat oven to 400°F (200°C). Line a baking sheet with parchment for easy cleanup.
  2. Pat the fish dry: Use paper towels to remove excess moisture so the seasoning sticks and the fish bakes, not steams.
  3. Make the lemon-herb mixture: In a small bowl, mix olive oil, lemon zest, lemon juice, garlic, Dijon, salt, pepper, oregano, thyme, and parsley.
  4. Season the cod: Place fillets on the sheet.Spoon the mixture evenly over the top and sides. Top each piece with a lemon slice.
  5. Bake: 10–14 minutes, depending on thickness. The fish is done when it flakes easily with a fork and reaches 145°F (63°C) internally.Thinner fillets might be done at 10 minutes; thicker pieces need a couple more.
  6. Finish and serve: Rest 2 minutes. Sprinkle with extra parsley and a squeeze of lemon. Serve with a simple salad, rice, or roasted asparagus.

What Makes This Recipe So Good

  • Quick and low-fuss: About 5 minutes of prep and the oven does the rest.
  • Clean, bright flavor: Lemon, garlic, and herbs wake up mild cod without overpowering it.
  • Versatile: Works with fresh or frozen cod and pairs with almost any side.
  • Good for you: Lean protein, heart-healthy fats, and simple ingredients you recognize.
  • Reliable results: A simple method that keeps the fish moist and flaky every time.

What You’ll Need

  • 1.5 to 2 pounds cod fillets (about 4 pieces), fresh or thawed
  • 2 tablespoons olive oil
  • Zest of 1 lemon
  • Juice of 1 lemon (about 2–3 tablespoons)
  • 2–3 garlic cloves, minced
  • 1 teaspoon Dijon mustard (optional but adds depth)
  • 1 teaspoon kosher salt
  • 1/2 teaspoon black pepper
  • 1 teaspoon dried oregano
  • 1 teaspoon dried thyme or Italian seasoning
  • 2 tablespoons fresh parsley, chopped (plus more for garnish)
  • Lemon slices, for topping

Step-by-Step Instructions

  1. Prep the oven and pan: Heat oven to 400°F (200°C). Line a baking sheet with parchment for easy cleanup.
  2. Pat the fish dry: Use paper towels to remove excess moisture so the seasoning sticks and the fish bakes, not steams.
  3. Make the lemon-herb mixture: In a small bowl, mix olive oil, lemon zest, lemon juice, garlic, Dijon, salt, pepper, oregano, thyme, and parsley.
  4. Season the cod: Place fillets on the sheet.

    Spoon the mixture evenly over the top and sides. Top each piece with a lemon slice.

  5. Bake: 10–14 minutes, depending on thickness. The fish is done when it flakes easily with a fork and reaches 145°F (63°C) internally.

    Thinner fillets might be done at 10 minutes; thicker pieces need a couple more.

  6. Finish and serve: Rest 2 minutes. Sprinkle with extra parsley and a squeeze of lemon. Serve with a simple salad, rice, or roasted asparagus.

Storage Instructions

  • Fridge: Store leftovers in an airtight container for up to 2 days.
  • Reheat gently: Warm in a 300°F (150°C) oven for 8–10 minutes or microwave at 50% power in short bursts to avoid drying out.
  • Freezing: Cooked cod doesn’t freeze as well as raw.

    If you must, wrap tightly and freeze up to 1 month, but expect a softer texture after thawing.

Why This is Good for You

  • Lean protein: Cod delivers high-quality protein without heavy fats.
  • Heart-friendly: Olive oil offers monounsaturated fats, and a low-sodium approach keeps it balanced.
  • Nutrient boost: Lemon and herbs bring antioxidants and bright flavor without extra calories.

What Not to Do

  • Don’t overbake: Dry fish happens fast. Start checking at 10 minutes.
  • Don’t skip drying the fish: Moisture dilutes seasoning and prevents nice, even cooking.
  • Don’t drown it in lemon juice: Too much acid can make the texture mushy if the fish sits in it too long before baking.
  • Don’t pile fillets on top of each other: Give each piece space so heat circulates and cooks evenly.

Alternatives

  • Fish swaps: Use haddock, halibut, pollock, or tilapia. Adjust bake time for thinner fillets.
  • Herb variations: Try dill and chives for a softer, fresher flavor, or rosemary and basil for a more robust profile.
  • Creamy twist: Whisk in a spoon of Greek yogurt for a tangy coating.

  • Make it a bowl: Serve over herbed quinoa or orzo with cucumbers and tomatoes. For another bright bowl, try this Mediterranean Salmon Rice Bowl.
  • Low-carb side ideas: Roast asparagus or zucchini. If you’re in a low-carb mood, this quick favorite might inspire sides too: High Protein Low Carb Pizza Bowl.

Can I use frozen cod?

Yes.

Thaw completely in the fridge overnight or under cold running water in a sealed bag. Pat very dry before seasoning to avoid excess moisture.

How do I know when cod is done?

It should flake easily with a fork and look opaque throughout. An instant-read thermometer should read 145°F (63°C) in the thickest part.

Can I make this dairy-free and gluten-free?

It’s naturally dairy-free and gluten-free as written.

Just confirm your Dijon is gluten-free if needed.

What sauces go well with this?

A quick lemon-garlic yogurt sauce, a light dill aioli, or a drizzle of good olive oil works great. If you like creamy pastas on the side, consider this bright option: Lemon Cream Chicken Linguine for inspiration.

What sides pair best?

Roasted potatoes, steamed green beans, buttered rice, or a crisp salad. This fresh salad is a perfect match for lemony flavors: Lemon Asparagus Easter Salad.

I’m Jonah, and design is the lens through which I see everything—even dinner. After a decade sketching interfaces for apps, I found myself sketching suppers instead. Food became my way to balance beauty and simplicity, to make meals that feel as welcoming to the eye as they are to the tongue. I believe a plate can comfort as much as a conversation, and that a busy day deserves a meal that doesn’t just feed you, but invites you to pause, to savor. When I cook, I’m always asking: how can this dish feel like home in both flavor and form?
