Common Mistakes & How to Avoid Them
| Common Mistake | What Happens | The Easy Fix |
|---|---|---|
| Adding Raw Potatoes Directly | Potatoes remain hard while the shrimp overcook and turn rubbery. | Always par-cook/microwave potatoes for 5 minutes before assembling on the sheet pan. |
| Overcrowding the Pan | Ingredients steam instead of getting nicely roasted and caramelized. | Use a large rimmed half-sheet pan (18×13 inches) or split between two pans. |
| Using Pre-Cooked Shrimp | Pre-cooked shrimp double-cook in the oven and become tough and chewy. | Always use raw, thawed shrimp for the juice to absorb the garlic butter glaze. |
Storage & Reheating Guidelines
- Refrigeration: Store cooled leftovers in an airtight container in the refrigerator for up to 3 days.
- Reheating: Reheat gently on a baking sheet at 350°F (175°C) for 8 to 10 minutes until warm, or warm in a skillet over medium-low heat. Avoid high microwave temperatures to keep shrimp tender.
