  • 4 cod fillets
  • 4 medium potatoes, peeled and thinly sliced
  • 1 cup heavy cream
  • 2 cloves garlic, minced
  • 2 tablespoons fresh rosemary, finely chopped
  • 2 tablespoons butter
  • Salt and pepper to taste
  • Olive oil for cooking


  1. Preheat your oven to 375°F (190°C).
  2. In a saucepan, melt the butter over medium heat. Add the minced garlic and cook until fragrant, about 1-2 minutes.
  3. Add the heavy cream to the saucepan and stir in the chopped rosemary. Season with salt and pepper to taste. Let the sauce simmer gently for 5-7 minutes, allowing the flavors to meld together. Remove from heat and set aside.
  4. In a large oven-safe dish, layer the thinly sliced potatoes evenly on the bottom.
  5. Place the cod fillets on top of the potatoes and season them with salt and pepper.
  6. Pour the rosemary cream sauce over the cod and potatoes, making sure everything is evenly coated.
  7. Drizzle a little olive oil over the top and cover the dish with aluminum foil.
  8. Bake in the preheated oven for 25-30 minutes, or until the cod is cooked through and the potatoes are tender.
  9. Remove the foil and broil for an additional 3-5 minutes to brown the top slightly.
  10. Serve hot, garnished with fresh rosemary sprigs if desired.

Creative Variations:

  1. Swap the Fish: While cod works beautifully in this recipe, you can easily substitute it with other white fish such as haddock, halibut, or tilapia. Each fish brings its own unique flavor and texture to the dish, so feel free to experiment and find your favorite.
  2. Herb Substitutions: Don’t have rosemary on hand? No problem! You can easily switch it out for other herbs like thyme, dill, or parsley. Each herb will impart its own distinct flavor profile to the dish, so pick your favorite or use a combination for added complexity.
  3. Add Some Heat: For a spicy kick, try adding a pinch of red pepper flakes to the cream sauce. This will give the dish a subtle heat that pairs beautifully with the creamy richness of the sauce.
  4. Cheese Please: Take this dish to the next level by sprinkling some grated Parmesan or Pecorino cheese over the top before baking. The cheese will melt into the creamy sauce, adding a savory depth of flavor that’s absolutely irresistible.
  5. Vegetarian Twist: Want to make this dish vegetarian? Simply omit the fish and double up on the potatoes or add in your favorite vegetables like sliced mushrooms, spinach, or cherry tomatoes. You’ll still get all the creamy deliciousness without the seafood.
  6. Citrus Zest: Brighten up the flavors of the dish by adding a sprinkle of lemon or orange zest to the cream sauce. The citrusy notes will add a refreshing contrast to the richness of the sauce and fish.
  7. Nutty Crunch: For added texture, consider topping the dish with a handful of toasted breadcrumbs or chopped nuts before baking. This will create a delightful crunchy topping that adds another layer of flavor and complexity.


  1. Choose Fresh Fish: When selecting cod fillets, look for ones that are firm, with a mild sea smell. Fresh fish should have clear eyes, bright red gills, and firm flesh. If possible, buy from a trusted fishmonger or seafood market.
  2. Pat Dry the Fish: Before seasoning the cod, make sure to pat it dry with paper towels. Removing excess moisture helps the seasoning adhere better and ensures the fish cooks evenly.
  3. Even Slicing: When slicing the potatoes, aim for uniform thickness to ensure they cook evenly. You can use a mandoline slicer for consistent results, or simply take your time with a sharp knife.
  4. Prevent Potatoes from Browning: If you’re slicing the potatoes ahead of time, place them in a bowl of cold water to prevent them from browning. This step also helps remove excess starch, resulting in crispier potatoes.
  5. Adjust Seasoning: Taste the cream sauce before pouring it over the fish and potatoes. Adjust the seasoning as needed with more salt, pepper, or rosemary to suit your preferences.
  6. Don’t Overcook: Keep an eye on the fish while it’s baking to prevent overcooking, which can result in a dry texture. The cod is done when it flakes easily with a fork and reaches an internal temperature of 145°F (63°C).
  7. Let it Rest: Allow the dish to rest for a few minutes after removing it from the oven. This allows the flavors to meld together and makes it easier to serve.
  8. Garnish for Presentation: Sprinkle some fresh chopped parsley or additional rosemary over the finished dish for a pop of color and added freshness.
  9. Serve with Sides: This dish pairs well with a variety of sides such as steamed vegetables, a green salad, or crusty bread to soak up the delicious sauce.
  10. Make Ahead: You can prepare the cream sauce and slice the potatoes ahead of time to save time on the day of cooking. Store the sauce in an airtight container in the refrigerator and keep the sliced potatoes submerged in water until ready to use.
