Ingredients
- For the roasted potatoes:
- 680 g Yukon Gold potatoes, cut into 2.5 cm pieces
- 2 tablespoons extra virgin olive oil
- 1 teaspoon kosher salt
- ½ teaspoon freshly ground black pepper
- For the rosemary cream sauce:
- 2 tablespoons unsalted butter
- 2 tablespoons extra virgin olive oil
- 2 shallots, finely chopped
- 4 garlic cloves, sliced
- 1 cup heavy cream
- 1 cup chicken broth
- 2 sprigs fresh rosemary
- 1 tablespoon Dijon mustard
- 1 tablespoon capers, drained
- 1 teaspoon lemon zest
- 1 tablespoon fresh lemon juice
- ½ teaspoon cayenne pepper
- Kosher salt and freshly ground black pepper, to taste
- For the fish:
- 680 g cod fillets, cut into individual portions

Substitution Options
If you can’t find Yukon Gold potatoes, red potatoes work just as well. For a dairy-free version, swap the heavy cream with coconut milk. Instead of cod, try using halibut or even salmon for a richer flavor. Fresh rosemary is ideal, but if you only have dried, use half the amount called for in the recipe.
Step 1: Preheat Your Oven
Start by preheating your oven to 220°C (425°F). This high heat will ensure your potatoes turn out crispy on the outside and soft on the inside. While the oven heats up, take a moment to admire the golden hue of the Yukon Golds—they’re the unsung heroes of this dish!
Pro tip: Line your baking sheet with parchment paper to make cleanup a breeze.
Step 2: Roast the Potatoes
Toss the potato chunks with olive oil, salt, and pepper until they’re evenly coated. Spread them out in a single layer on the baking sheet. Pop them in the oven for 20–25 minutes, flipping halfway through to ensure even browning. As they roast, your kitchen will fill with the irresistible aroma of caramelized goodness.
Step 3: Make the Rosemary Cream Sauce
In a medium saucepan, melt the butter and olive oil over medium heat. Add the shallots and garlic, sautéing until fragrant and translucent. Pour in the cream and chicken broth, then toss in the rosemary sprigs for an herby infusion. Stir in the mustard, capers, lemon zest, and juice, and let the sauce simmer until it thickens slightly. Taste and adjust seasoning—you want a balance of savory, tangy, and spicy notes.
Step 4: Assemble and Bake
Once the potatoes are done, arrange the cod fillets on top of them in the baking dish. Spoon the rosemary cream sauce generously over the fish and potatoes, ensuring everything is well-coated. Return the dish to the oven for another 12–15 minutes, or until the cod flakes easily with a fork. The sight of the bubbling sauce is almost too tempting to resist!
Timing
This recipe comes together quickly. Prep time is just 15 minutes, while cooking takes about 40 minutes. In total, you’ll have dinner ready in under an hour—a lifesaver on busy weeknights.
Chef’s Secret
For an extra burst of flavor, sprinkle a pinch of smoked paprika into the rosemary cream sauce. It adds a subtle smokiness that pairs beautifully with the cod.
Extra Info
Rosemary is known for its antioxidant properties, making it not only delicious but also nutritious. Its pine-like aroma is said to improve memory and concentration—perfect for those who need a little boost during meal prep!
Necessary Equipment
You’ll need a baking sheet, parchment paper, a medium saucepan, a sharp knife, and a spatula. Simple tools for a stunning result!
Storage
Leftovers can be stored in an airtight container in the refrigerator for up to three days. Reheat gently in the oven to preserve the texture of the fish and potatoes. Avoid microwaving, as it can make the cod rubbery.
If freezing, omit the cream sauce and store the components separately. Thaw overnight in the fridge before reheating.
To refresh the flavors after storage, drizzle a bit of olive oil and squeeze fresh lemon juice over the dish before serving.
Tips and Advice
Use fresh ingredients whenever possible—the difference in flavor is worth it. Don’t skip the capers; they add a briny kick that ties the dish together. Lastly, don’t overcrowd the baking sheet; giving the potatoes space helps them crisp up nicely.
Presentation Tips
- Garnish with freshly chopped parsley for a pop of color.
- Serve with lemon wedges for a bright finishing touch.
- Use a rustic wooden board or ceramic platter for a homely vibe.
Healthier Alternative Recipes
Here are six ways to lighten up this dish:
- Swap the cream: Use Greek yogurt instead of heavy cream for a protein-packed twist.
- Go low-carb: Replace the potatoes with roasted cauliflower florets.
- Add greens: Toss spinach or kale into the sauce for added nutrients.
- Try air-frying: Cook the potatoes in an air fryer to reduce oil usage.
- Use skin-on fish: Opt for cod with the skin on for extra flavor and moisture.
- Herb swap: Experiment with thyme or oregano instead of rosemary.
Mistake 1: Overcrowding the Baking Sheet
When roasting potatoes, crowding the pan leads to steaming rather than crisping. To avoid soggy spuds, spread them out evenly. Use two baking sheets if needed.
Mistake 2: Skipping the Sauce Reduction
Don’t rush the sauce-making process. Allowing it to simmer ensures the flavors meld and the consistency thickens. Patience pays off here!
Mistake 3: Overcooking the Cod
Cod cooks quickly, so keep an eye on it. Overcooked fish becomes dry and loses its delicate texture. Check for doneness at the 12-minute mark.
FAQ
Can I use frozen cod?
Yes, but thaw it completely before cooking. Pat it dry with paper towels to remove excess moisture, which helps achieve a better sear.
What sides pair well with this dish?
A simple green salad or steamed green beans complement the richness of the cod and potatoes beautifully.
Can I make the sauce ahead of time?
Absolutely! Prepare the sauce up to a day in advance and reheat it gently before assembling the dish.
Is this dish gluten-free?
Yes, as long as you use gluten-free chicken broth and Dijon mustard.
How do I know when the cod is cooked?
The cod should flake easily with a fork and have an opaque appearance. Avoid overcooking to maintain its tenderness.
Can I use dried rosemary instead of fresh?
Yes, but use half the amount since dried herbs are more concentrated in flavor.
What type of potatoes works best?
Yukon Golds are ideal due to their creamy texture, but red potatoes or baby potatoes are excellent substitutes.
Can I double the recipe?
Definitely! Just ensure you have enough baking sheets and pans to accommodate the larger quantities.
Why does my sauce taste bland?
Season generously with salt and pepper, and don’t forget the lemon juice—it adds brightness and balances the richness.
Can I add wine to the sauce?
Yes, deglaze the pan with white wine before adding the cream for an extra layer of complexity.
With this Cod Rosemary Cream recipe, you’ve got a dish that’s as satisfying to make as it is to eat. Whether you’re cooking for loved ones or treating yourself, this meal promises to deliver comfort and elegance in every bite.
