How to Make Cod & Potatoes in Rosemary Cream Sauce
Ingredients:
- 4 cod fillets (6 oz / 170 g each), fresh or thawed frozen
- Salt and black pepper, to taste
- 1–2 tbsp olive oil or butter for searing
- 1 lb (450 g) waxy potatoes (Yukon Gold, fingerling, or red), peeled and sliced evenly
- Salt and pepper, to taste
- 1 tbsp butter or olive oil
- 1 cup heavy cream
- 2 tbsp butter
- 2 cloves garlic, minced
- 1 small onion, finely chopped
- 1–2 sprigs fresh rosemary
- Optional: 2 tbsp white wine
- Optional: 1 tsp lemon juice
- Optional: 2 tbsp grated Parmesan
- Fresh rosemary sprigs, lemon wedges, or microgreens for garnish
Directions:
- Prepare Potatoes: Boil or roast the evenly sliced potatoes until they are tender, then season with salt and pepper.
- Prepare Cod: Pat the cod fillets dry and season them with salt and pepper. In a skillet, sear the fillets with olive oil or butter for 3–4 minutes on each side until they are golden and flaky. If you prefer, you can also bake them at 375°F (190°C) for about 8–10 minutes.
- Make Rosemary Cream Sauce: In another pan, sauté the minced garlic and chopped onion in butter until they are translucent. Then, add the cream and rosemary. Let it simmer gently for a few minutes, allowing it to reduce slightly. If you like, you can add white wine, lemon juice, or Parmesan for more flavor.
- Assemble Dish: Layer the cooked potatoes on plates or in a serving pan. Place the seared cod fillets on top of the potatoes, and pour the rosemary cream sauce over everything. For a nice finish, you can briefly broil the dish for a golden top and slight caramelization.
- Garnish & Serve: Before serving, add fresh rosemary, lemon wedges, or microgreens for a pop of color and flavor.
How to Serve Cod & Potatoes in Rosemary Cream Sauce
This dish can be served immediately, hot from the pan. It pairs well with a simple side salad or steamed vegetables. For a touch of elegance, serve in individual plates garnished with lemon wedges and fresh herbs. A glass of white wine also complements the flavors beautifully.
How to Store Cod & Potatoes in Rosemary Cream Sauce
Leftover cod and potatoes can be stored in an airtight container in the refrigerator for up to 2 days. Reheat gently in the microwave or on the stovetop over low heat. If you want to store for longer, consider freezing the sauce and potatoes separately from the cod, as fish tends to lose its texture when frozen.
Tips to Make Cod & Potatoes in Rosemary Cream Sauce
- Ensure the cod is patted dry before seasoning for a better sear.
- Use fresh rosemary for the best flavor, but dried rosemary can also work in a pinch.
- Adjust the amount of garlic and onion according to your personal taste preference.
- Don’t skip the optional ingredients like white wine or Parmesan—they add depth to the sauce.
- For a healthier version, consider using less cream or substituting with a light cream or milk.
Variation
You can add vegetables like spinach or asparagus to the dish for added nutrition. If you prefer a spicy kick, a pinch of red pepper flakes can enhance the flavor profile. Additionally, swapping cod for another white fish like haddock or tilapia works equally well.
