Final answer:
Pre-cooked fries should ideally rest for about 2 to 5 minutes after cooking. This lets them crisp up further and cool down to a more manageable temperature.
Step-by-step explanation:
When cooking pre-cooked fries, it's generally recommended to let them sit and rest for a few minutes after you take them out of the oven, fryer, or air fryer. This resting period allows the fries to cool slightly, which can help them crisp up further and makes them easier to handle and eat. Though specific instructions can vary depending on the brand of fries, a good rule of thumb is to let them rest for about 2 to 5 minutes. This brief interval is a perfect time to finish setting the table or getting your favorite condiments ready for a delicious meal.
