Ingredients

For the Cod and Potatoes

  • 2 cod fillets about 6 oz each
  • 4 –5 baby potatoes halved
  • 2 tablespoons olive oil
  • 1 teaspoon dried thyme
  • ½ teaspoon paprika
  • Salt and black pepper to taste

For the Rosemary Cream Sauce

  • 2 tablespoons butter
  • 2 cloves garlic minced
  • ½ cup chicken or vegetable broth
  • 1 cup heavy cream
  • 1 teaspoon Dijon mustard optional but recommended
  • 1 teaspoon dried rosemary or 1 tablespoon fresh
  • 1 tablespoon lemon juice
  • Fresh rosemary sprigs for garnish

Instructions

Step 1: Roast the Potatoes

  • Preheat the oven to 400°F (200°C).
  • Toss halved baby potatoes in 1 tablespoon of olive oil, dried thyme, salt, and black pepper.
  • Spread them on a baking sheet and roast for 20–25 minutes, flipping halfway through until golden and fork-tender.

Step 2: Sear the Cod

  • While the potatoes are roasting, season cod fillets with salt, black pepper, paprika, and a pinch of thyme.
  • Heat 1 tablespoon olive oil and 1 tablespoon butter in a skillet over medium-high heat.
  • Sear the cod for 3–4 minutes on each side until golden and just cooked through. Remove and set aside.

Step 3: Make the Creamy Rosemary Sauce

  • In the same skillet, melt the remaining 1 tablespoon of butter.
  • Add minced garlic and sauté for about 1 minute until fragrant.
  • Pour in the broth and let it simmer for 2–3 minutes, scraping up any brown bits.
  • Stir in the heavy cream, Dijon mustard (if using), and rosemary.
  • Let the sauce simmer for 3–4 minutes until slightly thickened.

Step 4: Assemble and Finish

  • Return the roasted potatoes to the skillet and stir gently into the cream sauce.
  • Nestle the seared cod fillets on top and drizzle everything with lemon juice.
  • Simmer for another 2 minutes so the flavors meld together.
  • Garnish with fresh rosemary and serve hot.
