Step-by-Step Instructions

Step 1: Roast the Potatoes

1. Preheat your oven to 400°F (200°C).
2. Toss 1 lb of halved baby Yukon Gold potatoes with 2 tbsp extra virgin olive oil, salt, and freshly cracked black pepper.
3. Arrange cut-side down in a baking dish and roast for 20–25 minutes until golden brown and fork-tender.

Step 2: Sear the Cod

1. Heat 1 tbsp extra virgin olive oil in a skillet over medium-high heat.
2. Thoroughly pat 4 thick-cut cod fillets dry with paper towels, then season with salt and pepper.
3. Pan-sear for 4 minutes on the first side without moving the fillets until a deep golden crust forms.

Step 3: Make the Lemon-Rosemary Cream Sauce

1. In a pan, heat 1 tbsp extra virgin olive oil over medium heat. Sauté 1 finely chopped shallot and 3 minced garlic cloves for 2 minutes until translucent.
2. Whisk in 1/2 cup low-sodium vegetable or chicken stock, 1/2 cup Greek yogurt, 2 tsp Dijon mustard, 2 tbsp fresh lemon juice, 1 tsp lemon zest, a pinch of cayenne pepper, and 2 sprigs of fresh rosemary.
3. Simmer on low heat for 3–4 minutes until smooth, glossy, and warm.

Step 4: Combine & Finish Baking

1. Remove the baking dish with roasted potatoes from the oven.
2. Nestle the pan-seared cod fillets among the potatoes.
3. Discard the rosemary sprigs and pour the creamy lemon sauce evenly over the top.
4. Bake at 400°F (200°C) for 8–10 minutes until the fish flakes easily with a fork. Garnish with fresh rosemary leaves and extra lemon zest before serving.

Chef’s Tips for Success

1. Dry the Fish: Excess moisture prevents proper browning. Pat the cod thoroughly with paper towels before seasoning.
2. Do Not Overcrowd the Pan: Sear cod in batches if your pan is small to ensure maximum crispness.
3. Low Simmer for Yogurt: Keep the flame low when adding Greek yogurt to prevent curdling.

Frequently Asked Questions (FAQs)

1. Can I use frozen cod fillets for this recipe?

Yes! Frozen cod fillets work very well. However, be sure to thaw them completely in the refrigerator overnight before cooking. Once thawed, pat them thoroughly dry with paper towels—removing excess moisture is critical to getting a deep, crisp sear on the fish rather than steaming it in the pan.

2. How do I prevent Greek yogurt from curdling in the sauce?

Greek yogurt can curdle if exposed to rapid high heat. To prevent this, reduce the heat to low before whisking in the yogurt, and gentle simmer the sauce for only 3 to 4 minutes. Using full-fat Greek yogurt also helps, as its higher fat content resists breaking better than non-fat or low-fat options.

3. What white fish can I substitute for cod?

If cod is unavailable, high-quality white fish fillets such as halibut, haddock, mahi-mahi, or sea bass make great substitutes. Look for thick-cut fillets so they don’t overcook when pan-seared and finished in the oven.

4. Can I make this recipe dairy-free?

Absolutely. Replace the Greek yogurt with full-fat canned coconut cream or a smooth emulsion of extra virgin olive oil and broth. Both options complement the lemon and rosemary flavor profile nicely without sacrificing the sauce’s silky texture.

5. How long do leftovers last, and how should I reheat them?

Store leftover cod and potatoes in an airtight container in the refrigerator for up to 2 days. Reheat gently in a 350°F (175°C) oven until warmed through (about 10 minutes) to maintain the texture of the potatoes and keep the fish tender. Avoid microwaving, as it can cause white fish to become rubbery.
