Tips & Variations
- Use Yukon Gold potatoes for a creamy texture that holds up well during baking.
- Fresh rosemary works best, but dried rosemary can be used—reduce quantity to 1 tablespoon.
- For extra flavor, add a squeeze of lemon juice over the cod before baking.
- Substitute cod with other white fish like haddock or halibut if preferred.
- To make it lighter, use half-and-half instead of heavy cream, though the sauce will be less rich.
Storage
Store any leftovers in an airtight container in the refrigerator for up to 2 days. Reheat gently in the oven or microwave to avoid drying out the fish and potatoes.

FAQs
Can I prepare this dish in advance?
Yes, you can assemble the dish up to the baking step and refrigerate it covered for a few hours before cooking. Just add a few extra minutes to the baking time if baking straight from the fridge.
What is the best way to tell when the cod is cooked?
The cod is done when it flakes easily with a fork and appears opaque all the way through. It should reach an internal temperature of 145°F (63°C) if using a food thermometer.

Ingredients
Potatoes
- 4 medium potatoes, peeled and thinly sliced
Sauce
- 1 cup heavy cream
- 2 cloves garlic, minced
- 2 tablespoons fresh rosemary, finely chopped
- 2 tablespoons butter
- Salt and pepper to taste
Additional
- Olive oil for cooking and drizzling
- 2 cod fillets (about 6 oz each)
Instructions
- Preheat Oven: Preheat your oven to 375°F (190°C) to prepare for baking the dish evenly.
- Prepare Cream Sauce: In a saucepan over medium heat, melt the butter. Add the minced garlic and sauté for 1-2 minutes until fragrant, taking care not to brown the garlic excessively. Pour in the heavy cream and stir in the chopped rosemary. Season the sauce with salt and pepper, then let it simmer gently for 5-7 minutes to allow the flavors to meld. Remove from heat and set aside.
- Layer Potatoes: In a large oven-safe baking dish, arrange the thinly sliced potatoes in an even layer at the bottom to ensure uniform cooking.
- Add Cod Fillets: Place the cod fillets on top of the potato layer and season both the fish and potatoes with salt and pepper to enhance the flavor.
- Pour Sauce and Add Oil: Pour the prepared rosemary cream sauce evenly over the cod and potatoes, making sure everything is well coated. Drizzle a small amount of olive oil on top to aid browning and add richness.
- Bake Covered: Cover the dish tightly with aluminum foil to retain moisture and bake in the preheated oven for 25-30 minutes, or until the cod is fully cooked and the potatoes are tender when pierced with a fork.
- Broil to Finish: Remove the foil and switch the oven to broil. Broil the dish for an additional 3-5 minutes to brown the top slightly and develop a lovely golden crust.
- Serve: Serve hot, optionally garnished with fresh rosemary sprigs for an aromatic and attractive presentation.
Notes
- Ensure the potatoes are sliced uniformly thin to guarantee even cooking.
- Do not overcook the garlic when sautéing; it should be fragrant but not browned.
- Covering the dish during baking helps keep the moisture in, preventing the cod from drying out.
- Broiling at the end adds a beautiful color and slight crispness to the surface.
- Fresh rosemary is preferred for the best flavor, but dried rosemary can be used in a pinch—reduce quantity by half.
