Ingredients

For the Main Dish

• 4 cod fillets (about 6 oz each), skinless and boneless
• 1 lb baby potatoes or Yukon Golds, halved
• 2 tablespoons olive oil
• 1 tablespoon butter
• Salt and black pepper, to taste

For the Rosemary Cream Sauce

• 2 tablespoons butter
• 3 garlic cloves, minced
• 1 teaspoon fresh rosemary, finely chopped (or ½ tsp dried rosemary)
• 1 cup heavy cream
• ½ cup chicken or vegetable broth
• ½ cup grated Parmesan cheese
• 1 tablespoon Dijon mustard (optional, for depth)
• Juice of ½ lemon
• Salt and pepper, to taste

Optional Garnishes

• Fresh parsley, chopped
• Extra rosemary sprigs
• Lemon wedges for serving

Instructions

1. Prepare the Potatoes

Preheat your oven to 400°F (200°C).
Place the halved potatoes on a baking sheet and drizzle with olive oil, salt, and pepper. Toss well to coat.
Roast for 20–25 minutes, or until golden and tender.
(Tip: You can also boil the potatoes if you prefer a softer texture, but roasting adds more flavor.)

2. Sear the Cod

While the potatoes cook, pat the cod fillets dry with paper towels and season both sides with salt and pepper.
Heat 1 tablespoon olive oil and 1 tablespoon butter in a large skillet over medium-high heat.
Add the cod fillets and cook for 3–4 minutes per side, or until golden brown and just cooked through. Remove from the skillet and set aside.

3. Make the Rosemary Cream Sauce

In the same skillet, reduce the heat to medium. Add 2 tablespoons of butter and the minced garlic. Sauté for about 30 seconds until fragrant.
Stir in the chopped rosemary and cook for another 30 seconds.
Add chicken broth and heavy cream, stirring to combine. Bring to a gentle simmer.
Whisk in Parmesan cheese and Dijon mustard (if using). Simmer for 2–3 minutes, allowing the sauce to thicken slightly.
Add the lemon juice and season with salt and pepper to taste.

4. Combine and Serve

Add the roasted potatoes to the skillet and toss gently to coat them in the sauce.
Nestle the cooked cod fillets back into the pan, spooning some sauce over the top.
Simmer on low heat for 2–3 minutes, just until the fish is warmed through and everything is coated in the creamy rosemary sauce.
Garnish with fresh parsley and a squeeze of lemon juice before serving.

Serving Suggestions

Serve your Cod & Potatoes in Rosemary Cream Sauce with:

• Steamed green beans or asparagus
• A crisp green salad with lemon vinaigrette
• Crusty bread to soak up that luscious sauce
• Or even over rice or pasta for a heartier meal

Storing and Reheating

Refrigerate: Store leftovers in an airtight container for up to 2 days.
Reheat: Warm gently in a skillet over low heat. Add a splash of milk or cream to loosen the sauce if it thickens too much.
Freeze: It’s best enjoyed fresh, as the cream sauce may separate when frozen.

Helpful Tips for Perfect Results

• Use fresh rosemary for the best flavor — dried can be a bit harsh if overused.
• Don’t overcook the cod. It should flake easily but stay moist and tender.
• For a lighter sauce: Use half-and-half or evaporated milk instead of heavy cream.
• For extra richness: Stir in a small knob of butter just before serving.
