  • Total Time: 50 minutes
  • Yield: 4 servings

Ingredients

Seasoning Mixture

  • 3 tablespoons olive oil
  • 1 tablespoon Old Bay seasoning
  • 1 teaspoon rubbed sage
  • Kosher salt, to taste
  • Fresh cracked pepper, to taste

Main Ingredients

  • 1.5 pounds baby gold potatoes
  • 1 pound cod fillet

Mustard Cream Sauce

  • 3/4 cup heavy cream
  • 1/4 cup chicken broth
  • 1/4 cup capers
  • 2 cloves garlic, finely minced
  • 2 tablespoons Dijon mustard
  • 2 tablespoons stone-ground mustard
  • 1 tablespoon lemon juice
  • Kosher salt, to taste
  • Fresh cracked pepper, to taste

Garnishes

  • Fresh chopped parsley
  • Freshly sliced chives
  • Lemon wedges

Instructions

  1. Heat Oven: Preheat your oven to 400 degrees Fahrenheit to get it ready for baking the potatoes and fish.
  2. Mix Seasoning: In a small bowl, combine olive oil, Old Bay seasoning, rubbed sage, and add large pinches of kosher salt and freshly cracked pepper. This will be used to season the potatoes and fish.
  3. Prep and Bake Potatoes: Place the baby gold potatoes in a 9×13 baking dish. Drizzle about two-thirds of the prepared oil mixture over the potatoes and toss to coat them evenly. Bake in the preheated oven for 20 to 25 minutes until the potatoes are tender but not fully cooked through.
  4. Make Cream Sauce: While the potatoes bake, whisk together the heavy cream, chicken broth, capers, minced garlic, Dijon mustard, stone-ground mustard, lemon juice, and add salt and pepper to taste. This creamy mustard sauce will complement the fish and potatoes.
  5. Add Fish: After the potatoes have partially baked, remove the baking dish from the oven and push the potatoes aside to create a well in the center. Pat the cod fillets dry, then drizzle the remaining seasoned oil over both sides of the fish. Nestle the cod into the center well of the potatoes.
  6. Add Sauce and Bake: Pour the mustard cream sauce over the cod and potatoes evenly. Return the baking dish to the oven and bake for another 10 to 15 minutes until the cod flakes easily with a fork and the potatoes are fully tender.
  7. Garnish and Enjoy: Remove from the oven and garnish with fresh chopped parsley, freshly sliced chives, and lemon wedges. Serve immediately and enjoy your flavorful baked fish and potatoes.

Notes

  • You can substitute cod with other white fish fillets like haddock or pollock if preferred.
  • Adjust the seasoning to your taste, especially the amount of Old Bay and mustard in the sauce.
  • Using baby gold potatoes ensures quicker baking, but you can cube larger potatoes to similar size for even cooking.
  • For a thicker sauce, reduce the cream slightly before adding the other ingredients.
  • Ensure the fish is dry before seasoning to help the oil and spices adhere better.
