Ingredients Method Notes

Ingredients
  

  • 4 cod fillets – Fresh cod works best for a tender flaky texture.
  • 1 pound baby potatoes – Halved for even cooking; they absorb the sauce beautifully.
  • 2 tablespoons olive oil – Adds richness and helps crisp the potatoes.
  • 3 cloves garlic – Freshly minced for a bold aromatic flavor.
  • 1 cup heavy cream – Creates the rich velvety sauce.
  • ½ cup chicken broth – Balances the cream and adds depth.
  • 1 tablespoon fresh rosemary – Finely chopped; fresh gives the best aroma.
  • 1 tablespoon butter – Enhances the creaminess of the sauce.
  • Salt – Enhances all the flavors.
  • Black pepper – Adds mild heat and balance.
  • Lemon juice optional – Brightens the dish and cuts through the richness.

Method
 

  1. Start by heating olive oil in a large skillet over medium heat. Add the halved baby potatoes and cook until they are golden and tender. Stir occasionally to ensure even cooking and avoid burning. Season lightly with salt and pepper as they cook.
  2. In the same pan, add butter and minced garlic, letting it cook until fragrant. Pour in the chicken broth and heavy cream, stirring gently. Add chopped rosemary and let the sauce simmer until slightly thickened and aromatic.
  3. Place the cod fillets into the skillet or transfer everything to a baking dish. Spoon the creamy sauce over the fish to coat it well. Make sure the cod sits nestled among the potatoes for even cooking.
  4. Transfer the dish to a preheated oven and bake until the cod is opaque and flakes easily. The sauce will thicken further, and the flavors will blend beautifully. Keep an eye on the fish to avoid overcooking.
  5. Remove from the oven and let it rest briefly before serving. Add a splash of lemon juice if desired for freshness. Garnish with extra rosemary or herbs for a beautiful presentation.

Notes

  • I always use fresh rosemary because it gives a stronger, more natural flavor.
  • I recommend not overcooking the cod; it should stay soft and flaky.
  • I like to sear the potatoes until slightly crispy for better texture.
  • I sometimes add a pinch of chili flakes for a subtle heat kick.
  • I prefer tasting the sauce before baking to adjust salt and seasoning.
