Step‑by‑Step Instructions for Cod and Potatoes with Rosemary Cream Sauce
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This temperature ensures that your baby Yukon Gold potatoes roast perfectly, developing a golden, crispy exterior while remaining tender inside. While the oven heats up, gather your baking sheet and prepare for the next step.
Step 2: Prepare the Potatoes
Halve the baby Yukon Gold potatoes and place them in a bowl. Drizzle them with olive oil, then season generously with salt and pepper. Toss until evenly coated, then spread them out on your baking sheet in a single layer. Roast in the preheated oven for 25-30 minutes, or until they are golden brown and fork-tender.
Step 3: Season the Cod
While the potatoes are roasting, pat your cod fillets dry with paper towels. This ensures a beautiful sear later. Season both sides of the fillets generously with salt and pepper, allowing the flavors to penetrate the fish. As the potatoes finish roasting, reposition yourself to start cooking the cod.
Step 4: Sear the Cod
In a large skillet, melt 1 tablespoon of butter and heat a splash of olive oil over medium-high heat. Once hot, carefully add the seasoned cod fillets. Sear for 3-4 minutes on each side, or until they are golden brown and cooked through, appearing flaky and opaque. Transfer the cod to a plate and keep warm.
Step 5: Sauté Garlic and Rosemary
Reduce the heat to medium and return to the skillet. Add the remaining tablespoon of butter, allowing it to melt before adding minced garlic. Sauté for about 30 seconds, stirring constantly to avoid burning. Then, add the chopped fresh rosemary and sauté for another 30 seconds, releasing its aromatic oils into the butter.
Step 6: Make the Cream Sauce
Pour the heavy cream into the skillet, stirring to combine it with the garlic and rosemary. Allow the mixture to simmer gently for 3-4 minutes until it thickens slightly, stirring occasionally. Adjust seasoning with salt and pepper; the sauce should be silky and rich, perfectly complementing the cod and potatoes.
Step 7: Combine Cod and Potatoes
Carefully return the seared cod to the skillet, nestling it within the rosemary cream sauce. Add the roasted potatoes, ensuring they are coated in the sauce. Allow everything to simmer together for about 2 minutes, letting the flavors meld beautifully before plating.
Step 8: Serve and Garnish
Once heated through, transfer the Cod and Potatoes with Rosemary Cream Sauce to serving plates. For a finishing touch, sprinkle fresh parsley over the top for color and brightness. Serve hot and enjoy this comforting meal that elevates any weeknight dinner into a special occasion.

Cod and Potatoes with Rosemary Cream Sauce Recipe FAQs
What kind of cod should I use for this recipe?
Absolutely! When selecting cod fillets, look for thick, firm pieces that have a fresh, mild scent. Fresh cod should not have any dark spots or a fishy odor. If you can’t find cod, other white fish like haddock or halibut can work as a delicious substitute.
How should I store leftovers of the Cod and Potatoes with Rosemary Cream Sauce?
Store leftovers in an airtight container in the refrigerator for up to 2 days. It’s important to let the dish cool completely before sealing to ensure freshness. If you find that the sauce thickens too much upon refrigeration, simply add a splash of cream or water when reheating to restore its creamy texture.
Can I freeze the Cod and Potatoes with Rosemary Cream Sauce?
Yes, you can! To freeze, portion the cod and potatoes into a freezer-safe container, making sure to leave some space for expansion. They can be safely frozen for up to 1 month. When you’re ready to enjoy, thaw overnight in the refrigerator. Reheat gently on the stove over low heat, adding a bit of cream or water if needed to adjust the sauce’s consistency.
What if my cream sauce separates while cooking?
If your cream sauce begins to separate, don’t worry! The key to avoiding this is to keep the heat medium-low and let it simmer gently, rather than boil. If it does separate, quickly whisk in a couple of tablespoons of cold cream to bring it back together. If you notice your sauce is too thick, you can add a little more cream or chicken broth to help restore its velvety texture.
Are there any dietary considerations I should keep in mind?
Very! This dish is naturally gluten-free, which makes it a great option for those with gluten sensitivities. However, always check your ingredients, especially packaged items like broth or cream, to ensure they meet your dietary needs. If cooking for pets, remember that certain ingredients like garlic can be harmful to them, so it’s best to keep their portions separate if they’re accustomed to eating with the family!
