Instructions

Prepare the Potatoes

1. Preheat oven to 400°F (200°C).
2. Toss halved baby potatoes with olive oil, salt, pepper, and chopped rosemary.
3. Spread potatoes on a baking sheet in a single layer.
4. Roast for 25–30 minutes, until golden brown and tender, turning halfway through.

Cook the Cod

6. Season cod fillets with salt and pepper.

Make the Rosemary Cream Sauce

8. In the same skillet, melt butter over medium heat.
9. Add minced garlic and sauté 1 minute until fragrant.
10. Pour in heavy cream and bring to a gentle simmer.
11. Stir in fresh rosemary, salt, and pepper. Simmer 3–4 minutes until sauce thickens slightly.

Tips & Creative Notes

• Cod: Ensure the fillets are fresh and not frozen for the best texture.
• Potatoes: Baby potatoes roast evenly; if using larger potatoes, cut into uniform pieces.
• Sauce: For extra richness, add a sprinkle of Parmesan cheese into the cream sauce.
• Herbs: Fresh rosemary is preferred; dried rosemary can be substituted but use half the quantity.
• Serving: Pair with a crisp green salad or roasted vegetables for a complete meal.
