How to Make Roasted Cod with Potatoes and Lemon
Step 1: Preheat the Oven
Preheat your oven to 425°F (220°C). Adjust the oven rack to the lower-middle position for optimal roasting.

- Microwave uncovered until just tender, about 5 to 10 minutes. Stir once or twice during cooking.
Step 3: Arrange the Potatoes
- On a lined baking sheet, arrange the potatoes in four portions resembling rectangles (approximately 4 by 6 inches or 10 by 15 cm).
- Overlap the edges slightly for even cooking.
Step 4: Add the Cod Fillets
- Pat each cod fillet dry using paper towels; season with salt and pepper.

Common Mistakes to Avoid
To ensure your Roasted Cod with Potatoes and Lemon turns out perfectly, avoid these common mistakes.
- Ignoring potato thickness: Slicing potatoes too thickly can result in uneven cooking. Aim for 1/4-inch rounds for even tenderness.
- Skipping seasoning: Failing to season the fish and potatoes can lead to bland flavors. Make sure to sprinkle salt and pepper generously.
- Not preheating the oven: Baking in a cold oven may lead to longer cooking times. Always preheat your oven to 425°F (220°C) before starting.
- Overcrowding the baking sheet: Placing too many ingredients on one sheet can cause steaming instead of roasting. Ensure there’s enough space between the fillets and potatoes.
- Using frozen fish: Frozen fish may not cook evenly, affecting texture and flavor. Opt for fresh, skinless firm white fish fillets for best results.
