Common mistakes
One common mistake is overcooking the shrimp, which makes them tough. Stick to the recommended cooking time and check for doneness early. Another mistake is adding too much liquid, as the shrimp and vegetables release moisture during cooking.
This recipe is designed to be saucy, but not watery. Also, avoid lifting the lid too often, as this releases heat and extends cooking time. Finally, don't skip the Old Bay — it's the flavor backbone of this dish.
How to tell it’s done
The shrimp are done when they are pink and opaque, and the internal temperature reaches 145°F (63°C). The sauce should be bubbling and fragrant, and the vegetables should be tender but still have a little bite.
Be careful not to overcook, as shrimp can become tough and rubbery. The butter sauce should be glossy and well combined.
- Shellfish: 145°F (63°C) in the thickest part
