How many seconds should each side of a grilled cheese cook?

The recommended cooking time for each side of a grilled cheese sandwich is typically around 20 to 25 seconds. This duration allows the bread to become golden brown and crispy while ensuring that the cheese melts adequately. Cooking it for this time range strikes a balance between achieving the right texture and flavor without burning the bread or leaving the cheese unmelted.

The other time frames provided do not align as closely with traditional cooking methods for grilled cheese. Times shorter than 20 seconds may not allow the cheese to melt adequately, resulting in an unsatisfactory sandwich, while times longer than 25 seconds could risk burning the bread and drying out the sandwich. This makes the choice of 20 to 25 seconds an optimal recommendation for grilling a perfect cheese sandwich.
