Fragrant Cod Potatoes in Rosemary Cream Sauce

One rainy evening last fall, my younger brother and I decided to host a small dinner for some close friends. I wanted something comforting but elegant, a dish that smelled as inviting as it tasted. Inspired by a cozy seafood bistro I visited in Austin, I experimented with cod and creamy potatoes, infusing the sauce with fresh rosemary and a hint of lemon.

The aroma alone—garlic, butter, and rosemary mingling in the kitchen—made everyone gather around the stove, eager to taste. As the cod baked nestled among golden potatoes, I felt that familiar joy of creating something that warms both the stomach and heart.

By the time we sat down to eat, the creamy sauce, tender fish, and perfectly roasted potatoes had already won over my friends. It reminded me how simple ingredients, treated with care, can create memorable meals.

Short Description

Tender cod and roasted Yukon gold potatoes bathed in a creamy rosemary-lemon sauce, finished with capers for a zesty touch—a comforting yet refined dish.

Key Ingredients

• 3 tablespoons extra-virgin olive oil, divided
• 1 pound Yukon gold potatoes, cut into 1-inch pieces
• 2 teaspoons kosher salt, divided
• ¼ teaspoon freshly cracked black pepper
• 2 tablespoons salted butter
• 1 large shallot, chopped
• 3 cloves garlic, minced
• 1 cup heavy cream
• ½ cup chicken or fish stock
• 2 sprigs fresh rosemary
• 1 teaspoon lemon zest
• 2 tablespoons fresh lemon juice (about 1 lemon)
• 2 teaspoons Dijon mustard
• ¼ teaspoon ground cayenne pepper
• 2 tablespoons capers, drained
• 1 pound cod fillet, cut into 4 pieces
• 2 tablespoons chopped fresh parsley (optional, for garnish)

Tools Needed

• 8×8-inch baking dish
• Medium saucepan
• Skillet or roasting pan
• Wooden spoon
• Chef’s knife
• Cutting board

Cooking Instructions

Step 1: Roast the potatoes
Preheat the oven to 450°F and position a rack in the center. Grease the baking dish with 1 tablespoon olive oil. Toss potatoes with 1 tablespoon olive oil, 1 teaspoon salt, and black pepper.

Spread evenly and roast 20–25 minutes until tender and lightly golden, turning halfway for even browning.

Step 2: Make the rosemary cream sauce
In a medium saucepan, melt butter with remaining 1 tablespoon olive oil over medium heat. Sauté shallot 5 minutes until soft. Add garlic and cook 1 minute until fragrant.

Stir in cream, stock, rosemary, lemon zest, lemon juice, Dijon mustard, cayenne, and capers. Simmer gently 5 minutes, stirring occasionally, until slightly thickened. Remove rosemary sprigs before pouring over the fish.

Step 3: Bake the cod
Season cod with remaining 1 teaspoon salt. Nestle cod pieces among roasted potatoes in the baking dish. Pour warm rosemary cream sauce over fish and potatoes. Bake uncovered 10–15 minutes until cod flakes easily with a fork and potatoes are golden.

Step 4: Garnish and serve
Sprinkle with parsley if desired. Serve immediately, savoring the creamy, citrus-kissed sauce with tender fish and roasted potatoes.

FAQs

1. Can I use other types of fish? Cod is mild, but halibut or haddock works well.

2. Can I make this dairy-free? Substitute butter with olive oil and cream with coconut or cashew cream.

3. What if my potatoes cook faster than the fish? Partially roast them, then add the fish for final baking.

4. Can I prepare ahead? Roast potatoes and make sauce up to a day in advance; bake fish before serving.

5. How to prevent sauce from separating? Keep heat moderate and stir gently while simmering.

Tips & Tricks

Cut potatoes evenly for uniform roasting.

Use fresh lemon juice for brightness—bottled juice lacks vibrancy.

Gently fold fish into potatoes to avoid breaking fillets.

Recipe Variations
