🥔 Ingredients
- 4 cod fillets (about 5–6 oz each)
- 1 lb baby potatoes, halved or quartered
- 2 tablespoons olive oil
- Salt and pepper, to taste
- 1 tablespoon butter
- 2 garlic cloves, minced
- 1 cup heavy cream
- ½ cup chicken or vegetable broth
- 1 tablespoon fresh rosemary, finely chopped (or 1 tsp dried)
- Zest of 1 lemon
- 1 tablespoon lemon juice
- Optional garnish: fresh parsley or extra lemon zest
👩🍳 Instructions
- Par-cook the potatoes:
Bring a pot of salted water to a boil. Add potatoes and boil for 8–10 minutes, until just tender. Drain and set aside. - Sear the cod:
Pat cod fillets dry and season both sides with salt and pepper. In a large skillet, heat 1 tablespoon olive oil over medium heat. Sear cod for 2–3 minutes per side until lightly golden. Transfer to a plate (they’ll finish cooking in the sauce). - Make the rosemary cream sauce:
In the same skillet, add butter and garlic. Sauté for 30 seconds. Add cream, broth, chopped rosemary, lemon zest, and juice. Stir and bring to a gentle simmer. - Add potatoes and cod:
Nestle the potatoes and cod back into the sauce. Cover and cook on low for 5–7 minutes until the fish is cooked through and the sauce is slightly thickened. - Serve hot, spooning extra sauce over each serving. Garnish with parsley or more lemon zest if desired.
💡 Tips
- Pat cod dry before searing to get a better golden crust.
- Use baby Yukon gold potatoes for buttery texture and quick cooking.
- Don’t let the cream boil vigorously—gentle simmering keeps it smooth.
- Add extra broth if the sauce thickens too much as it simmers.
🔁 Variations & Substitutions
- Use other white fish like haddock, tilapia, or halibut.
- Try sweet potatoes or cauliflower instead of baby potatoes for a twist.
- Swap rosemary for thyme or dill for a different herb profile.
- Make it dairy-free: Use full-fat coconut milk or a cashew cream substitute.
❓ FAQs
Can I use frozen cod?
Yes—just thaw it completely and pat it dry before cooking to avoid excess water.
Can I make this ahead?
The sauce is best fresh, but you can prep the potatoes and sauce a few hours ahead. Reheat gently and add the cod just before serving.
How do I know when the cod is cooked?
Cod is done when it flakes easily with a fork and is opaque all the way through.
Can I bake this instead of using the stovetop?
Yes! After searing the cod and making the sauce, bake everything together at 375°F (190°C) for about 10–12 minutes.
🍽️ Serving Suggestions
- Serve with a side of steamed green beans, roasted asparagus, or sautéed spinach.
- Pair with crusty bread or garlic toast to soak up the sauce.
- Add a crisp green salad with a lemon vinaigrette for balance.
- Enjoy with a glass of chilled white wine like Chardonnay or Sauvignon Blanc.
