Chef’s Pro Tips for Perfect Results

Want to nail this dish on your very first try? Here are some insider secrets…

• Pat the cod dry – This helps it sear nicely without steaming.
• Slice potatoes evenly – Uniform slices ensure they cook at the same rate.
• Infuse the cream – Let the rosemary mingle in the sauce for at least 5 minutes before serving for maximum flavor.
• Don’t overcook the cod – It should flake easily but still stay moist.

Ingredients

Here’s what you’ll need to make this creamy dream come true:

1. Base & Protein

1. 1 ½ lbs fresh cod fillets
2. 1 ½ lbs baby potatoes, thinly sliced

2. Sauce & Seasoning

3. 2 tbsp olive oil
4. 3 tbsp butter
5. 3 cloves garlic, minced
6. 1 cup heavy cream
7. 1 cup chicken or vegetable broth
8. 1 tsp fresh rosemary, finely chopped (plus extra for garnish)
9. Salt and black pepper, to taste

3. Finishing Touches

10. Fresh lemon wedges, for serving
11. Optional: grated Parmesan for extra richness

Instructions

1. Prep the potatoes
Heat the olive oil in a large skillet over medium heat. Add the sliced potatoes, season with salt and pepper, and cook until golden and tender on both sides, about 8–10 minutes. Transfer the potatoes to a plate and set aside.

2. Sear the cod
Pat the cod fillets dry with paper towels. Season both sides with salt and pepper. In the same skillet, melt the butter, then sear the fillets until lightly golden and nearly cooked through, about 2–3 minutes per side. Remove and set aside.

3. Make the sauce
In the same pan, add the minced garlic and sauté for 30 seconds until fragrant. Pour in the broth and cream, then stir in the rosemary. Let the sauce simmer gently for 5 minutes so the flavors meld.

4. Combine everything
Return the potatoes and cod to the skillet, spooning the sauce over the top. Simmer for 3–4 more minutes, or until the fish flakes easily with a fork and the potatoes are fully tender.

5. Serve
Garnish with fresh rosemary and a squeeze of lemon juice. Serve hot with crusty bread to soak up every drop of the creamy sauce.

Texture & Flavor Secrets

The magic of this dish lies in the layers: the silky cream sauce infused with piney rosemary, the fluffy potato centers with crispy edges, and the delicate, buttery cod. Each bite is a perfect balance of rich, savory, and bright.

• Stuff a wrap – Use as a creamy filling with spinach in a tortilla.

Additional Tips

• Use fresh rosemary – It gives the sauce its signature flavor.
