I grew up near the coast, where fresh fish was always on the table. One rainy afternoon, I baked cod with potatoes for the first time. The fish turned flaky, and the potatoes got that perfect crunch. It became my go-to meal for busy days. This recipe keeps things simple and full of flavor, delivering a healthy dinner that’s ready in under an hour. Below, you’ll find everything you need to make this dish, optimized for both search engines and your kitchen.

What You’ll Need

• 1.5 pounds Yukon gold potatoes, sliced into 1/4-inch rounds
• 3 tablespoons olive oil, divided
• 4 garlic cloves, minced
• Salt and black pepper, to taste
• 1.5 pounds cod fillets, about 1-inch thick, skinless
• 2 tablespoons unsalted butter, cut into small pieces
• 4 sprigs fresh thyme
• 1 lemon, thinly sliced
• 2 tablespoons capers, drained (optional for a tangy twist)

How to Make Crispy Baked Cod with Roasted Potatoes

1. Preheat your oven to 425°F. Line a large sheet pan with parchment paper.
2. Toss potato slices with 2 tablespoons olive oil, minced garlic, salt, and pepper in a bowl.
3. Spread potatoes in a single layer on the sheet pan. Overlap slightly to form four rectangular bases, each about 4 by 6 inches.
4. Bake potatoes for 20 minutes until they start to soften and brown at the edges.
5. Pat cod fillets dry with paper towels. Season both sides with salt and pepper.
6. Remove sheet pan from oven. Place one cod fillet on each potato base.
7. Drizzle fillets with remaining 1 tablespoon olive oil. Top each with butter pieces, thyme sprigs, lemon slices, and capers if using.
8. Bake for 10-12 more minutes until cod flakes easily with a fork and reaches 145°F inside. Potatoes should be crispy underneath.
9. Let rest for 2 minutes before serving.

Substitutions

• Use russet potatoes instead of Yukon gold for extra starch and crisp.
• Swap cod for haddock or halibut for a similar white fish texture.
• Replace thyme with rosemary or dill for a different herb flavor.
• For dairy-free, use more olive oil instead of butter.
• Add red pepper flakes to the potato toss for a mild spicy note.

Storage and Make-Ahead Tips

• Storage: Keep leftovers in an airtight container in the fridge for up to 2 days. Reheat in a 350°F oven for 10 minutes to maintain crispness. Avoid microwaving to prevent soggy textures.
• Make-Ahead: Slice potatoes and season cod up to 4 hours ahead. Store covered in the fridge until ready to bake. This cuts prep time for busy evenings.

Tips and Variations

• Check cod doneness by gently pressing with a fork. It should flake but stay moist.
• For extra crisp, broil for the last 2 minutes. Watch closely to avoid burning.
• Add cherry tomatoes to the sheet pan in step 4 for a sweet burst.
• Mix in olives for a Mediterranean twist.
• If potatoes stick, use more parchment or foil next time.

Common Questions Answered

• How do I keep cod from drying out? Bake at 425°F for just 10-12 minutes and check for flakiness. The butter and lemon keep it moist.
• Can I use frozen cod? Thaw completely in the fridge overnight and pat dry before seasoning.
• What potatoes work best? Yukon gold gives a creamy inside with crispy edges, but russets work for extra crunch.
