Ingredients

Fish

  • 4-6 cod pieces, approximately 1.5 lbs
  • Salt and pepper to taste

Sauce

  • 1 cup (200 ml) sour cream or creme fraiche
  • 3 tbsp Dijon mustard
  • 1 tbsp whole-grain mustard
  • 1 leek, white part only, minced
  • 1 tbsp drained capers
  • 1 tbsp fresh parsley, chopped

Instructions

  1. Preheat the oven. Set your oven to 425°F (210°C) to prepare for roasting the cod.
  2. Prepare the baking dish. Butter a skillet or shallow baking dish, then arrange the cod pieces evenly within it. Sprinkle salt and pepper over the fillets to season.
  3. Make the mustard sauce. In a medium bowl, combine the sour cream (or creme fraiche), Dijon mustard, whole-grain mustard, minced leek, and drained capers. Mix thoroughly until smooth and well combined.
  4. Coat the cod with sauce. Spoon the prepared mustard sauce evenly over the cod fillets, ensuring each piece is well covered in a creamy layer of sauce.
  5. Roast the cod. Place the dish in the preheated oven and roast uncovered for 10-12 minutes, allowing the fish to cook through and the sauce to meld with the cod.
  6. Broil for finishing touch. Change your oven setting to broil/grill and cook for an additional 2-3 minutes. This will blister the sauce slightly, adding texture and flavor.
  7. Garnish and serve. Remove the cod from the oven, sprinkle fresh chopped parsley on top, and serve immediately for a hot, flavorful meal.

Notes

  • Use fresh cod fillets for the best texture and flavor.
  • Creme fraiche can be substituted with sour cream depending on availability.
  • Adjust mustard quantities based on your preferred tanginess level.
  • Serving with steamed vegetables or a light salad pairs well to keep the meal balanced.
  • Keep an eye on the broiling step to avoid burning the sauce.
