How long take to prepare a well done hamburger?

The cooking time for a well-done hamburger patty depends on the thickness of the patty and the cooking method. Here are the general guidelines for cooking a well-done hamburger on a stovetop:

1. Thick patty (over 1 inch thick):

- Medium-high heat: 6-8 minutes per side

- Low heat: 12-15 minutes per side

2. Thin patty (less than 1 inch thick):

- Medium-high heat: 3-4 minutes per side

- Low heat: 6-8 minutes per side

These cooking times are for grilling hamburgers on a stovetop. If you're using a different cooking method, such as a grill or oven, the cooking times may vary. It's important to use a meat thermometer to ensure that the internal temperature of the patty has reached 160°F (71°C) for well done.
