Cod and Potatoes in Rosemary Cream Sauce

by

Tender, flaky cod and golden baby potatoes come together in a luxurious rosemary cream sauce that feels restaurant-worthy but is easy enough for a weeknight. Infused with garlic, herbs, and a touch of Dijon, this one-pan-style dish is rich, comforting, and perfect for cooler evenings or an elevated family dinner.

Ingredients

For the Cod & Potatoes

  • 2 cod fillets (about 6 oz each)

  • 4–5 baby potatoes, halved

  • 2 tbsp olive oil

  • 1 tsp dried thyme

  • ½ tsp paprika

  • Salt & black pepper, to taste

For the Rosemary Cream Sauce

  • 2 tbsp butter

  • 2 cloves garlic, minced

  • ½ cup chicken or vegetable broth

  • 1 cup heavy cream

  • 1–2 tsp fresh rosemary, finely chopped

  • 1 tsp Dijon mustard (optional but recommended)

Instructions

  1. Prep the Potatoes
    Preheat oven to 400°F (200°C). Toss halved potatoes with olive oil, thyme, paprika, salt, and pepper. Arrange cut-side down on a baking dish or oven-safe skillet.

  2. Roast
    Roast potatoes for 20–25 minutes, until lightly golden and fork-tender.

  3. Season the Cod
    Pat cod fillets dry and season both sides with salt and pepper.

  4. Make the Sauce
    In a skillet over medium heat, melt butter. Add garlic and sauté for 30 seconds until fragrant.
    Stir in broth, cream, rosemary, and Dijon. Simmer 3–4 minutes until slightly thickened.

  5. Combine & Bake
    Nestle cod fillets among the potatoes. Pour rosemary cream sauce over everything.

  6. Finish Cooking
    Return to the oven and bake for 12–15 minutes, until the cod flakes easily and the sauce is bubbling.

  7. Serve
    Spoon sauce generously over the fish and potatoes. Garnish with extra rosemary if desired.

Notes

  • Cod is done when it reaches 145°F (63°C) internally.

  • Fresh rosemary gives the best flavor, but dried works in a pinch (use ½ tsp).

  • Sauce will thicken more as it rests.

Tips for Best Results

  • Dry the cod well before seasoning for better texture.

  • Don’t overbake—cod cooks fast.

  • For extra richness, finish with a squeeze of lemon or a sprinkle of Parmesan.

Servings

  • 2 hearty servings

  • Easily doubled for 4 people
