What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples, and you can easily find them at your local grocery store.

Cod fillets (about 1 lb / 450 g): Fresh or thawed, skinless and boneless are best for even cooking.
Potatoes (3 medium, about 450 g): Yukon Gold or red potatoes work great for their creamy texture.
Heavy cream (1 cup / 240 ml): Adds richness; you can swap for half-and-half for a lighter option.
Fresh rosemary (2-3 sprigs): The star herb that gives this dish its signature aroma.
Garlic cloves (2, minced): For that subtle, savory kick.
Butter (2 tbsp / 28 g): Unsalted, for a smooth base.
White wine (1/4 cup / 60 ml, optional): Adds a lovely depth; you can replace with chicken or vegetable broth.
Salt and freshly ground black pepper: To taste.
Olive oil (1 tbsp): For sautéing garlic and rosemary.
Lemon juice (1 tbsp, optional): Brightens the flavors before serving.

I recommend using firm, fresh cod from a trusted fishmonger or a reputable brand for the best texture. Look for small-curd butter to get that smooth melting quality, and fresh rosemary is a must—dried just won’t do here. If you’re short on fresh herbs, a teaspoon of dried rosemary can work but use sparingly to avoid overpowering the dish.

Equipment Needed

Large skillet or sauté pan: A heavy-bottomed pan works best for even heat distribution when cooking the potatoes and simmering the sauce.
Pot for boiling potatoes: Medium-sized with a lid.
Sharp knife and cutting board: For prepping garlic, rosemary, and potatoes.
Wooden spoon or silicone spatula: To stir the sauce gently without scratching your pan.
Measuring cups and spoons: For precise ingredient amounts.
Colander: To drain the potatoes.

If you don’t have a heavy skillet, a non-stick pan will do, but keep an eye on the heat to avoid burning the butter. I’ve also used a cast-iron skillet for this recipe and loved how it kept the sauce warm on the table. For budget-friendly options, basic stainless steel pans work perfectly fine and are easy to clean after that creamy sauce.

Preparation Method

Prepare the potatoes: Peel if you prefer (I usually leave the skin on for texture), then cut into 1-inch (2.5 cm) chunks. Place them in a pot, cover with cold water, add a pinch of salt, and bring to a boil. Cook until tender but not falling apart, about 12-15 minutes. Drain and set aside.
Prep the cod: Pat the cod fillets dry with paper towels, then season both sides with salt and freshly ground black pepper. Set aside while you start the sauce.
Make the rosemary cream sauce: In your skillet over medium heat, melt the butter with olive oil. Add the minced garlic and rosemary sprigs. Sauté gently for 1-2 minutes until fragrant but not browned.
Add the white wine: Pour in the white wine (or broth), scraping any bits off the pan bottom. Let it simmer and reduce by half, about 3-4 minutes.
Stir in the cream: Pour in the heavy cream, season with salt and pepper, and bring to a low simmer. Allow the sauce to thicken slightly, about 5 minutes. Watch closely so it doesn’t boil over.
Cook the cod in the sauce: Nestle the cod fillets gently into the sauce. Cover the pan with a lid or foil, reduce heat to low, and let the fish poach for 8-10 minutes. The cod should be opaque and flake easily with a fork.
Add the potatoes: Carefully fold the cooked potatoes into the rosemary cream sauce, stirring gently to coat without breaking them up.
Finish with lemon juice: Just before serving, drizzle the lemon juice over the dish to brighten the flavors. Remove rosemary sprigs.
Serve immediately: Spoon the cod, potatoes, and sauce onto plates and enjoy warm.

Pro tip: If your sauce feels too thick, add a splash of cream or broth to loosen it up. And don’t rush the poaching step—the gentle simmer keeps the cod tender and juicy every time. I’ve learned the hard way that high heat makes the fish tough, so patience really pays off here.

Cooking Tips & Techniques

Cooking cod in a rosemary cream sauce is all about gentle heat and timing. I’ve found that poaching the fish directly in the sauce keeps it moist and infuses it with flavor. Avoid boiling the cream; a slow simmer is the way to go.

One mistake I made early on was overcooking the cod—once it flakes easily, it’s done. Overcooked cod turns dry and rubbery, and you don’t want that in a comforting dish like this.

When boiling potatoes, don’t let them get mushy. You want them tender enough to pierce with a fork but still holding shape so they don’t disintegrate in the sauce.

Timing is key: prep your potatoes first so they’re ready to go when the sauce is simmering. While the sauce thickens, you can clean up or set the table—multitasking saves time and keeps things smooth.

Finally, fresh rosemary is crucial. It adds a piney, earthy note that dried herbs just can’t match. If you’re feeling fancy, try adding a small pinch of smoked paprika for a subtle twist—it’s a personal favorite!

Variations & Adaptations

Dietary swap: Use coconut cream or cashew cream instead of heavy cream for a dairy-free version. The flavor changes slightly but still delicious.
Seasonal twist: In warmer months, add fresh peas or asparagus tips to the sauce for a bright pop of color and flavor.
Flavor boost: Add a teaspoon of Dijon mustard to the cream sauce for a tangy edge that pairs beautifully with the cod.
Alternative fish: If you can’t find cod, haddock or halibut make great substitutes with similar texture and flavor.
Cooking method: For a roasted version, bake the potatoes separately until crispy, then top with pan-poached cod and drizzle with rosemary cream sauce right before serving.

I once tried adding sun-dried tomatoes for a Mediterranean flair—unexpected but tasty! It’s a flexible recipe that welcomes your personal spin.

Serving & Storage Suggestions

This dish is best served hot, straight from the pan, to enjoy the creamy sauce at its luscious best. I like to garnish with a small sprig of fresh rosemary or a sprinkle of chopped parsley for color.

Pair it with a crisp green salad or steamed green beans to add freshness and balance out the richness. A chilled glass of Sauvignon Blanc or a light Chardonnay complements the flavors beautifully.

Leftovers keep well in the fridge for up to 2 days in an airtight container. Reheat gently on the stovetop over low heat, adding a splash of cream or broth to loosen the sauce if it thickens too much.

Freezing isn’t ideal due to the cream, but if you must, freeze the fish and potatoes separately from the sauce. Thaw overnight and reheat carefully to avoid curdling.

Flavors meld wonderfully after a day, so if you have time, making this a day ahead can deepen the taste—just be mindful of reheating gently!

Nutritional Information & Benefits

This comforting cod and potatoes recipe provides a balanced meal rich in protein, healthy fats, and complex carbs. Cod is a lean fish packed with omega-3 fatty acids, which support heart health. Potatoes offer good fiber and potassium, important for muscle function and blood pressure regulation.

Using heavy cream adds richness but also calories, so if you’re watching intake, consider half-and-half or plant-based cream alternatives. The rosemary contributes antioxidants and a lovely herbal aroma that can aid digestion.

This dish fits well into gluten-free diets as long as you use gluten-free broth or wine substitutes. Keep in mind any dairy allergies and swap ingredients accordingly.

Conclusion

In a world full of complicated meals, this comforting cod and potatoes recipe stands out for its simplicity, flavor, and soul-satisfying feel. It’s the kind of dish that makes you pause and appreciate the beauty of straightforward cooking done well.

Feel free to tweak it to your taste—add a splash of white wine, swap herbs, or try your favorite potato variety. I love how versatile it is, and it always feels like a little celebration on the plate.
