The 5 6 7 rule for grilling burgers is a guideline for grilling burgers, which helps you achieve consistent doneness of the grilled burger, which is based on cooking time per side.
This is assuming you have a 1/2 inch to 3/4 inch thick hamburger patty, over medium heat.
The 5 6 7 rule for burgers suggests that you grill the burgers for 5 minutes per side for rare to medium rare, 6 minutes for medium and grill the burgers for 7 minutes for well done.
This helps to ensure that you get a nice juicy burger on the grill without needing a thermometer.
5 minutes of cooking per side when grilling the burgers, produces a burger that is rare to medium rare.
6 minutes of cooking per side produces a burger that is medium done.
And 7 minutes of cooking per side produces a burger on the grill that is well done.
So if you want your grilled burger to be rare to medium rare, you would grill the burgers for 5 minutes per side.
If you want your grilled burger to be medium done, you would grill your burger for 6 minutes per side.
And if you want your grilled burger to be done fully, then you would grill your burger for 7 minutes per side.
Also don't press down on the burgers when grilling them, to prevent drying the burgers out.
And the 5 6 7 rule for grilling burgers also works best on a grill that is preheated to 350 F to 400 F with 80/20 ground beef.
And some interpretations of the 5 6 7 rule, define it as 5 minutes on one side, 6 minutes on the other side and a 7 minute rest period for maximum juiciness.
