Main Ingredients

  • 4 pieces cod fillets (150–180g each), skinless and boneless Use the freshest cod available.
  • 500 g baby potatoes or Yukon Gold potatoes, halved or quartered Ensure even cooking by cutting potatoes into similar sizes.
  • 2 tablespoons olive oil
  • 1 tablespoon butter
  • 1 teaspoon salt To taste
  • 1 teaspoon pepper To taste
  • 1 tablespoon lemon juice
  • 1 piece zest of 1 lemon
  • 3 cloves garlic, finely minced
  • 1 small shallot or onion, finely chopped
  • 1 teaspoon fresh rosemary, finely chopped (or ½ teaspoon dried rosemary)
  • 1.5 cups heavy cream Substitute with full-fat coconut milk for a dairy-free option.
  • 0.5 cup halal-certified chicken or vegetable broth
  • 0.5 teaspoon Dijon mustard (optional)
  • as needed for garnish Fresh parsley or chives Optional for garnish.

Instructions
 

Preparation

  • Wash the potatoes thoroughly and cut them into halves or quarters.
  • Place in a pot of salted boiling water; cook for 8–10 minutes until fork-tender. Drain and set aside.
  • Pat the cod fillets dry with paper towels. Season with salt, pepper, lemon juice, and lemon zest, allowing them to marinate briefly.

Cooking

  • Heat 2 tablespoons of olive oil and 1 tablespoon of butter in a large skillet over medium-high heat.
  • Add the cod fillets to the pan, searing for 3–4 minutes on each side until lightly golden and cooked through. Remove and keep warm.
  • In the same skillet, lower the heat to medium. Add olive oil, garlic, and shallots, sautéing for 2–3 minutes until fragrant and translucent.
  • Stir in the chopped rosemary, cooking for another minute.
  • Pour in the broth; bring it to a gentle simmer, then add the heavy cream and Dijon mustard if using.
  • Let the sauce simmer for 6–8 minutes, stirring occasionally until it thickens slightly.
  • Return the boiled potatoes to the skillet, gently tossing them in the sauce for 3–4 minutes.
  • Carefully place the seared cod back into the skillet, spooning sauce over each fillet. Simmer everything together on low heat for an additional 2–3 minutes.
  • Garnish with freshly chopped parsley or chives, if desired. Serve hot.

Notes

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days or frozen for up to 2 months. For serving, consider pairing with a light side salad or crusty bread.
