Shrimp are usually cooked for 2-8 minutes. Generally, how many minutes you need to cook shrimp depends on the size of the shrimp:

1. Small shrimps such as shrimps only need to be cooked in boiling water for 2-3 minutes to be completely cooked.

2. Medium-sized shrimp. For example, prawns need to be cooked for 4-5 minutes.

3. Prawns. For example, lobster may need to be cooked for 6-8 minutes. In addition, the specific time will vary slightly depending on the type and condition of the shrimp. For example, the above time refers to the cooking time after the water is boiled, not when the water is boiled. Also, if the shrimp has been thawed ahead of time or left at room temperature for a while, the cooking time may be slightly shorter. In short, the time for cooking shrimp should be adjusted according to the actual situation to ensure the taste and nutritional value of the shrimp.
