Cod & Potatoes in Rosemary Cream Sauce Ingredients
For the Roasted Potatoes
• Extra-Virgin Olive Oil – Adds flavor and aids in roasting; can substitute with any neutral oil.
• Yukon Gold Potatoes – Provides a creamy texture when roasted; red or russet potatoes can also be used.
• Kosher Salt – Enhances flavor; use coarse salt for better distribution.
• Freshly Cracked Black Pepper – Adds spice and depth; white pepper can be used for a milder flavor.
For the Rosemary Cream Sauce
• Salted Butter – Contributes richness to the sauce; unsalted butter may be substituted for less salt.
• Shallot – Offers a sweet, mild onion flavor; red onion can work in a pinch.
• Garlic – Adds aromatic flavor; fresh garlic is recommended for the best taste.
• Heavy Cream – Forms the lush base of the sauce; for a lighter sauce, use half-and-half or whole milk.
• Chicken or Fish Stock – Enhances the sauce flavor; homemade stock is ideal, or use vegetable stock for a non-meat option.
• Fresh Rosemary – Provides fragrance and earthiness; if fresh is not available, use ½ teaspoon dried rosemary.
• Lemon Zest – Adds brightness and freshness; organic lemons are best to avoid pesticide residue.
• Fresh Lemon Juice – Balances the richness of the cream; freshly squeezed juice is preferable for flavor.
• Dijon Mustard – Adds a tangy note to the sauce; yellow mustard can be used for a milder flavor.
• Ground Cayenne Pepper – Gives a hint of heat; adjust to taste or omit for less spice.
• Capers – Introduce briny accents; you can use chopped green olives if you don’t have capers.
For the Main Dish

Step‑by‑Step Instructions for Cod & Potatoes in Rosemary Cream Sauce
Step 1: Roast the Potatoes
Preheat your oven to 450°F (232°C). Grease an 8×8 baking dish and combine the Yukon gold potatoes with extra-virgin olive oil, kosher salt, and freshly cracked black pepper. Toss until evenly coated. Spread the potatoes in a single layer and roast for 20-25 minutes, or until they are tender and golden brown, turning them halfway through for even cooking.
Step 2: Prepare the Rosemary Cream Sauce
While the potatoes roast, melt 2 tablespoons of salted butter and heat 2 tablespoons of the remaining olive oil in a saucepan over medium heat. Sauté the shallot for about 5 minutes until soft and translucent, then add minced garlic and cook for an additional minute until fragrant. Pour in 1 cup of heavy cream and ½ cup of chicken or fish stock, then stir in fresh rosemary, lemon zest, lemon juice, Dijon mustard, cayenne pepper, and capers. Simmer the sauce for 5-7 minutes until thickened.
Step 3: Assemble the Dish
Once the potatoes are roasted, remove them from the oven and lower the temperature to 400°F (204°C). Season the cod fillet with kosher salt, and place it amongst the golden roasted potatoes in the baking dish. Pour the warm rosemary cream sauce over the cod and potatoes, ensuring everything is well coated for maximum flavor.
Step 4: Bake and Serve
Bake the assembled dish uncovered in the oven for 10-15 minutes. The cod is done when it flakes easily with a fork and has turned opaque. Remove the baking dish from the oven and let it sit for a couple of minutes before garnishing with chopped fresh parsley. Serve your Cod & Potatoes in Rosemary Cream Sauce hot, paired with crusty bread or a crisp green salad for a complete meal.
