For the Cod & Potatoes

Cod Fillet – Main protein; look for firm, moist flesh, or substitute with halibut for a similar texture.
Yukon Gold Potatoes – Base starch; their silky sweetness makes them perfect for roasting, but red potatoes work too if needed.
Extra Virgin Olive Oil – Essential for sautéing and roasting; easily replaceable with vegetable oil or melted butter.
Kosher Salt – Enhances flavor; adjust according to dietary needs or opt for a lower-sodium option.
Freshly Cracked Black Pepper – Adds depth; feel free to adjust based on your taste preferences.

For the Cream Sauce

Butter – Provides richness for the sauce; a dairy-free alternative or more olive oil can lighten things up.
Shallot – Aromatic base for flavor; yellow onion can be used as a quick substitute.
Garlic – Adds fragrance; fresh garlic is best, but garlic powder can work in a pinch.
Heavy Cream – Creates a rich sauce; for dairy-free options, full-fat coconut milk is an excellent replacement.
Chicken or Fish Stock – Adds umami flavor; vegetable broth can substitute for a vegetarian-friendly version.
Fresh Rosemary – Key herb for this dish’s flavor; if fresh isn’t available, dried rosemary can work, though the flavor will be milder.
Lemon Zest & Juice – Provides freshness; the juice brightens the overall dish; lime can also be a zesty substitute.
Dijon Mustard – Gives a sharp bite to the sauce; any mustard type will work in a pinch.
Ground Cayenne Pepper – Adds a touch of heat; you can omit it if preferred.
Capers – Bring a briny burst of flavor; skip them if you’re not a fan.
Minced Flat Leaf Parsley – An optional garnish that adds freshness to the dish.

Step‑by‑Step Instructions for Cod & Potatoes in Rosemary Cream Sauce

Step 1: Preheat the Oven
Start by preheating your oven to 450°F (232°C). Make sure the rack is positioned in the center to ensure even cooking. This high temperature will help achieve a beautifully roasted texture for your Yukon Gold potatoes.

Step 2: Prepare the Potatoes
While the oven is heating, wash and slice your Yukon Gold potatoes into 1-inch pieces. In a large mixing bowl, toss them with extra virgin olive oil, kosher salt, and freshly cracked black pepper. Spread the seasoned potatoes evenly in a greased 8×8-inch baking dish and roast for about 20-25 minutes, or until they are tender and golden.

Step 3: Make the Cream Sauce
As the potatoes roast, grab a saucepan and melt butter with a drizzle of olive oil over medium heat. Once the butter has melted, add finely chopped shallots and sauté for about 5 minutes until they turn translucent and tender. Stir in minced garlic and cook for an additional minute until fragrant, filling your kitchen with a delicious aroma.

Step 4: Add the Cream and Seasonings
Next, pour in heavy cream and chicken or fish stock into the saucepan with the shallots and garlic. Stir in the fresh rosemary, lemon zest, lemon juice, Dijon mustard, ground cayenne pepper, and capers. Bring the mixture to a gentle simmer, allowing it to thicken slightly for about 5 minutes while whisking occasionally to combine all the lovely flavors.

Step 5: Nestle in the Cod
Once your potatoes are beautifully roasted, remove the baking dish from the oven and nestle the cod fillets among the potatoes. Pour the luscious rosemary cream sauce evenly over the cod and potatoes, ensuring everything is coated. Return the dish to the oven and bake uncovered for an additional 10-15 minutes, or until the cod is flaky and opaque.

Step 6: Garnish and Serve
After the cod is done, take the baking dish out of the oven and let it rest for a couple of minutes. If desired, sprinkle fresh minced flat-leaf parsley over the top for a pop of color and extra flavor. Your Cod & Potatoes in Rosemary Cream Sauce is now ready to be served, perfect alongside a crisp salad or roasted asparagus!

Expert Tips for Cod & Potatoes in Rosemary Cream Sauce

Thaw Properly: Ensure frozen fish is completely thawed to avoid uneven cooking. Take it out the night before to make your dinner prep seamless.
Adjust Cooking Time: If using thicker cod fillets, slightly extend the baking time to ensure the fish reaches the perfect flakiness without overcooking.
Creamy Consistency: When replacing heavy cream with coconut milk, use full-fat for a rich, satisfying cream sauce that complements the other flavors perfectly.
Potato Monitoring: Keep an eye on your Yukon gold potatoes while roasting; overly browned potatoes can turn crispy instead of tender. You want them to be soft and lovely!
Be Bold with Herbs: Feel free to experiment with herbs beyond rosemary! Tarragon or thyme can add unique flavors to your Cod & Potatoes in Rosemary Cream Sauce, so get creative!

Cod & Potatoes in Rosemary Cream Sauce Recipe FAQs

How do I choose the best cod fillet?
Absolutely! When selecting cod fillet, look for firm and moist flesh that is translucent and free of any dark spots. Freshness is key, so don’t hesitate to ask your fishmonger for the day’s catch. Alternatively, halibut can be a great substitute for its similar texture and mild flavor.

What is the best way to store leftovers of this dish?
Leftovers can be stored in an airtight container in the fridge for up to 2 days. To reheat, I recommend gently warming it in the oven at 350°F (175°C) for about 15-20 minutes to keep the cod from overcooking and maintain that creamy texture!

Can I freeze the Cod & Potatoes in Rosemary Cream Sauce?
Yes! You can freeze this dish for up to 2 months. I suggest portioning it into freezer-safe containers to make thawing easier. When you’re ready to enjoy, thaw it overnight in the fridge, then reheat gently in the oven to restore its creaminess. To freeze effectively, try to separate the cod from the sauce to preserve the best flavor and texture.

What should I do if my potatoes are overcooked?
If your potatoes end up overcooked, try to embrace the texture and serve them as a creamy base for the cod and sauce. You can also replace any leftover potatoes with steamed green beans or asparagus for a fresh crunch in your next meal.

Are there any dietary considerations I need to be aware of?
Indeed! If you’re cooking for someone with dietary restrictions, consider using dairy-free alternatives, such as full-fat coconut milk instead of heavy cream. For those allergic to fish, you can swap the cod for firm tofu or roasted chickpeas for a vegetarian option while adjusting cook times accordingly.

How can I modify the flavors to suit personal tastes?
Very! Feel free to experiment by adding different herbs like tarragon or thyme for a unique twist. If you love a bit of spice, you can increase the cayenne pepper or add a sprinkle of chili flakes. Enjoy the process of tailoring it to match your palate!
