Cod and Potatoes with Rosemary Cream Sauce Ingredients
For the Cod

For the Potatoes
• Baby Yukon Gold Potatoes – These create a creamy texture and can be roasted whole or halved; fingerling or red potatoes work as great substitutions.

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 crucial step ensures that your baby Yukon Gold potatoes roast perfectly. While the oven heats, prepare your baking sheet by lining it with parchment paper or lightly greasing it with olive oil to prevent sticking.
Step 2: Prepare the Potatoes
Halve the baby Yukon Gold potatoes and place them in a mixing bowl. Drizzle with olive oil and season generously with salt and pepper. Toss everything together until the potatoes are evenly coated. Spread the seasoned potatoes on the prepared baking sheet in a single layer and roast them in the preheated oven for 25-30 minutes, or until they are golden and fork-tender.
Step 3: Season the Cod
While the potatoes are roasting, pat the cod fillets dry with paper towels to remove excess moisture—this helps achieve a beautiful crust. Season each fillet with salt and pepper on both sides, enhancing the flavor. Set the seasoned cod aside while you prepare to sear it in the next step.
Step 4: Sear the Cod
In a large skillet, heat 1 tablespoon of butter along with a splash of olive oil over medium-high heat. Once the butter is melted and bubbly, gently place the seasoned cod fillets in the skillet. Sear them for about 3-4 minutes on each side, or until they are golden brown and cooked through. Carefully transfer the cod to a plate and set aside.
Step 5: Sauté the Garlic
Lower the heat to medium and add the remaining tablespoon of butter to the same skillet. As it melts, add minced garlic and sauté for about 30 seconds, stirring constantly to prevent burning. The garlic should become fragrant and just start to turn golden, enriching the flavor of your rosemary cream sauce.
Step 6: Add Fresh Rosemary
Next, stir in the chopped fresh rosemary and continue to cook for another 30 seconds. This step releases the aromatic oils from the rosemary, infusing the butter and garlic with their earthy scent. The combination of garlic and rosemary is what makes this Cod and Potatoes with Rosemary Cream Sauce so exceptional.
Step 7: Create the Cream Sauce
Pour in the heavy cream and bring the mixture to a gentle simmer. Allow it to cook for 3-4 minutes, stirring occasionally, until it thickens slightly. Taste the sauce and season with a pinch of salt and pepper if needed, ensuring a well-balanced and creamy consistency.
Step 8: Combine Everything in the Skillet
Carefully return the seared cod fillets to the skillet, nestling them into the cream sauce. Add the roasted baby potatoes around the cod, allowing all the flavors to meld together. Simmer for an additional 2 minutes to warm everything through and enrich the flavors before serving.
Step 9: Garnish and Serve
Once everything is heated and well combined, sprinkle with freshly chopped parsley for a touch of color and freshness. Serve your Cod and Potatoes with Rosemary Cream Sauce hot, and watch as smiles surround the table. This comforting dish is perfect for any occasion!

Cod and Potatoes with Rosemary Cream Sauce Recipe FAQs
How do I select the best cod fillets?
When choosing cod fillets, look for thick, firm pieces that feel moist and have a slight sheen. Fresh fillets should have a mild, clean ocean scent and no discoloration. Avoid any that have dark spots or a strong fishy odor, as these are signs of age. If you can, purchase from a reputable fishmonger who can provide high-quality, sustainable options.
What is the best way to store leftovers?
To maintain the creamy texture and flavors of your Cod and Potatoes with Rosemary Cream Sauce, store any leftovers in an airtight container in the refrigerator for up to 2 days. It’s essential to let the dish cool to room temperature before sealing it to prevent moisture buildup, which can alter the dish’s quality.
Can I freeze Cod and Potatoes with Rosemary Cream Sauce?
Freezing this dish is possible, but it’s best to freeze the sauce separately from the cod and potatoes. Place the cooled sauce in a freezer-safe container and freeze for up to 3 months. When you’re ready to enjoy it, thaw overnight in the fridge and gently reheat on the stove. Note that the potatoes should not be frozen, as they might become mushy.
What should I do if the cream sauce separates while cooking?
If you find that your cream sauce is separating, it may be due to cooking at too high a temperature or boiling the sauce. To salvage it, lower the heat immediately and whisk in a little more cream or a tablespoon of cold butter until well combined. This should help bring it back to a smooth consistency.
Are there any dietary considerations I should be aware of?
This recipe is naturally gluten-free, but if you have specific dietary concerns, such as lactose intolerance, you can substitute the heavy cream with coconut cream or a dairy-free half-and-half alternative. Just be aware that it might change the flavor and texture slightly. Also, always check labels on any pre-packaged ingredients to ensure they meet your dietary needs.
How can I add more vegetables to this dish?
Absolutely! You can include extra vegetables like asparagus or spinach for added nutrition and color. Simply add them to the skillet during the last 2-3 minutes of cooking, allowing them to wilt slightly in the cream sauce. This creates a delightful balance and makes the dish even more wholesome while retaining its comforting essence.
