How to Make the best Cod & Potatoes in Rosemary Cream Sauce

Step 1: Roast the Potatoes

Get your oven heating to 450°F and prepare an 8×8-inch baking dish with a tablespoon of olive oil to prevent sticking. Toss the chopped Yukon gold potatoes with a tablespoon of olive oil, a teaspoon of kosher salt, and freshly cracked black pepper, coating them evenly so each piece crisps up beautifully. Spread them out in your dish in a single layer and roast for about 20 to 25 minutes. You’re aiming for tender, fork-ready potatoes finished with a delicate golden crust—a perfect foundation for our creamy sauce and tender fish.

Step 2: Make the Rosemary Cream Sauce

While those potatoes are roasting away, it’s time to build the sauce that turns this dish from simply good to unforgettable. Melt the butter and remaining olive oil in a medium saucepan over medium heat, then sautée the chopped shallot until it softens and releases its sweet aroma, about five minutes. Stir in the minced garlic, cooking just until fragrant, about one minute. Now pour in the heavy cream and chicken or fish stock, followed by the sprigs of fresh rosemary, lemon zest, lemon juice, Dijon mustard, cayenne pepper, and capers. Bring this mixture to a gentle simmer over medium-high heat, then reduce the heat, allowing it to thicken gently while stirring occasionally for about five minutes. The result is a luscious, herb-laced cream sauce with just the right touch of citrus to brighten every bite.

Step 3: Bake the Fish

Season the cod fillets with the final teaspoon of kosher salt for balanced seasoning. When the potatoes have emerged from the oven perfectly roasted, nestle the cod pieces snugly among them in the baking dish. Pour that warm, heavenly rosemary cream sauce generously over the fish and potatoes, making sure every corner is coated. Return the dish to the oven and bake uncovered for 10 to 15 minutes until the cod flakes easily when tested with a fork—this signals it’s cooked through but still tender and moist. At this stage, the flavors all marry beautifully, from the delicate fish to the rich sauce and crispy potatoes.

Step 4: Garnish and Serve

Once out of the oven, sprinkle freshly chopped parsley over the dish if you want to add a dash of color and a fresh herbal note. Serve this comforting meal hot, encouraging those around your table to savor each bite, rich with the creamy, citrusy goodness that makes the best Cod & Potatoes in Rosemary Cream Sauce so irresistibly wonderful.

How to Serve the best Cod & Potatoes in Rosemary Cream Sauce

Garnishes

A simple sprinkle of fresh parsley adds a burst of green that balances the creamy sauce and highlights the dish’s rustic elegance. You can also try a few extra capers on top for unexpected pops of briny flavor that contrast beautifully with the richness.

Side Dishes

Since this is already a hearty meal, light, crisp greens work best alongside. A simple arugula or baby spinach salad with lemon vinaigrette cuts through the creaminess and adds freshness. Steamed green beans or roasted asparagus are also excellent vegetable companions that bring vibrant color and texture.

Creative Ways to Present

For a refined look, plate individual portions layering the potatoes first, then the cod, finished by spooning the rosemary cream sauce generously over top. Serve with a lemon wedge on the side for guests who enjoy a burst of extra citrus at the table. For family-style dinners, use your baking dish as the centerpiece so everyone can serve themselves from this inviting, saucy delight.

Make Ahead and Storage

Storing Leftovers

After enjoying your meal, pack any leftovers into an airtight container and refrigerate for up to 3 days. Make sure the dish cools to room temperature before sealing to keep the fish and sauce fresh and flavorful.

Freezing

This dish doesn’t freeze as well because the cream sauce can separate and potatoes often lose their texture. It’s best to enjoy the best Cod & Potatoes in Rosemary Cream Sauce fresh, but if needed, freeze components separately—potatoes and fish without sauce for up to 1 month—to preserve the quality.

Reheating

When ready to enjoy leftovers, gently reheat in a covered oven-safe dish at 325°F until warmed through to avoid drying out the fish. You can also warm portions slowly on the stovetop over low heat, stirring the sauce occasionally to bring back its creamy consistency without scorching.

FAQs

Can I substitute the cod with another fish?

Absolutely! While cod’s mild flavor and flaky texture are ideal for this recipe, other white fish like haddock, halibut, or pollock will work wonderfully as well. Just adjust cooking time depending on thickness.

What if I don’t have heavy cream on hand?

You can make a lighter version using half-and-half or a blend of milk and a bit of cornstarch for thickening, but the sauce will be less rich and creamy. For that indulgent, velvety texture, heavy cream is the star.

Can I prepare this recipe ahead of time?

You can roast the potatoes and prepare the cream sauce a few hours ahead, then assemble and bake the fish shortly before serving. This helps save time without sacrificing freshness or flavor.

Is there a way to make this dish dairy-free?

Yes! Swap out butter for a dairy-free margarine and use coconut cream or a dairy-free cream alternative to keep the sauce creamy without dairy. The flavors will be slightly different but still delicious.

Why are Yukon gold potatoes recommended?

Yukon gold potatoes have a naturally buttery flavor and hold their shape well when roasted, making them perfect for this recipe. They absorb the sauce beautifully and add a gentle creaminess that balances perfectly with the fish.

There’s something truly special about the best Cod & Potatoes in Rosemary Cream Sauce that makes every bite feel like a celebration of simple, thoughtful cooking.
