What Kind of Potatoes Should I Use?

Yukon Gold or baby yellow potatoes work beautifully here. Their creamy texture complements the rich sauce and flaky fish without falling apart. If you’re using russet or red potatoes, just make sure to slice them evenly and parboil to soften before sautéing.

How To Make the Cod and Potatoes with Rosemary Cream Sauce

Step 1: Prepare the Potatoes

In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add halved baby potatoes cut side down and cook for 6-8 minutes until golden. Flip and cook another 4-5 minutes until tender. Season with salt and pepper. Remove and set aside.

Step 2: Sear the Cod

Pat cod fillets dry with paper towels. Season both sides with salt and pepper. In the same skillet, add another tablespoon of olive oil over medium-high heat. Sear cod for 3-4 minutes per side, depending on thickness, until golden and just cooked through. Remove cod and keep warm.

Step 3: Make the Rosemary Cream Sauce

Lower heat to medium. Add butter to the skillet and stir in minced garlic. Cook until fragrant, about 30 seconds. Pour in heavy cream and stir in Dijon mustard, chopped rosemary, and red pepper flakes if using. Let simmer for 3-5 minutes until the sauce thickens slightly.

Step 4: Combine and Serve

Return the potatoes to the skillet and gently toss to coat in the sauce. Nestle the cod fillets on top. Spoon sauce over the fish and finish with a squeeze of lemon juice. Serve immediately with extra rosemary or lemon wedges on the side.

Serving and Storing Your Cod and Potatoes with Rosemary Cream Sauce

This dish shines when served fresh from the skillet, with the cod still warm and the cream sauce silky. It’s perfect on its own or with a slice of toasted sourdough or a light arugula salad. Want to level it up? A chilled glass of white wine like Sauvignon Blanc pairs beautifully.

Leftovers can be stored in an airtight container in the fridge for up to two days. Reheat gently on the stove over low heat to avoid curdling the cream. The sauce may thicken in the fridge, so add a splash of cream or milk when reheating to bring it back to life.

Frequently Asked Questions

How do I know when cod is fully cooked?

Cod should be opaque and flake easily with a fork. Its internal temperature should reach 145°F (63°C).

Can I use frozen cod?

Yes, just make sure it’s completely thawed and patted dry before cooking to ensure a good sear.

What if I don’t have fresh rosemary?

Dried rosemary works in a pinch, but use only 1 teaspoon since it’s more concentrated.

Can I use another type of fish?

Absolutely. Halibut, haddock, or tilapia are great alternatives.

Is this dish gluten-free?

Yes! Just double-check your Dijon mustard brand to ensure it’s certified gluten-free.

Can I add vegetables to this?

You can toss in spinach or peas during the last minute of simmering for a pop of color and extra nutrition.
