Instructions

Preparation

  • Preheat your oven to 450°F (230°C). Lightly coat an 8×8-inch baking dish with 1 tablespoon of olive oil.
  • In a mixing bowl, toss the chopped Yukon gold potatoes with 1 tablespoon of olive oil, 1 teaspoon of salt, and black pepper to taste. Spread them out in the prepared baking dish and bake for 20–25 minutes or until they are tender and slightly golden.

Cooking the Sauce

  • While the potatoes are baking, heat 2 tablespoons of olive oil and the butter in a large skillet over medium heat. Add the chopped shallots and sauté them for about 5 minutes until soft and translucent.
  • Add the minced garlic and cook for an additional minute until fragrant.
  • Reduce the heat to low and stir in the heavy cream, chicken broth, rosemary, lemon zest, lemon juice, Dijon mustard, cayenne pepper, and capers. Let the mixture simmer for about 5 minutes.

Assembling and Baking

  • Season the cod fillet chunks with 1 teaspoon of salt. Once the potatoes are done, nestle the cod pieces over the roasted potatoes.
  • Pour the creamy sauce evenly over the cod and potatoes.
  • Return the dish to the oven and bake for an additional 10–15 minutes, or until the cod flakes easily with a fork.

Serving

  • If desired, sprinkle with fresh parsley. Serve hot, spoiling the delightful sauce over each serving.

Notes

For added flavor, consider adding thyme or dill. Ensure even cooking by having cod pieces of uniform size. For extra creaminess, you can include cream cheese in the sauce. For variations, try adding seasonal vegetables or different types of fish.
