The oil helps to “fry” the French fries a second time and get them extra crispy. Put the leftover fries in the hot oil in a single layer, making sure not to crowd the pan. Work in batches if need be.

There are no limits to how many times you can safely reheat leftover home-cooked meals. However, best practice is to limit the number of times you do so. More often than not, you wouldn't need to reheat one type of dish more than once.
If food has been hygienically prepared, cooled quickly after cooking (or reheating) and stored cold, reheating more than once should not increase the risk of illness. However, prolonged storage and repeated reheating will affect the taste, texture, and sometimes the nutritional quality of foods.

bacteria grow rapidly at temperatures between 40°F - 140°F. In general, cooked fries should be discarded after two hours if left at room temperature. A sealed container with fries will certainly accelerate the temperature and humidity that fuels bacteria growth, so figure even less time for safe consumption.

French fries, tater tots, and hash browns can keep in the freezer for six to 12 months. While like other frozen foods they will keep after that but to maintain flavor and texture try and eat them within the one-year mark.
When fries are cooked at a very high temperature, the starches in them are hydrated (moisture goes in), puffing them up and helping the outer skin get nice and crisp. When these same fries cool, the starches secrete moisture, which makes its way to the fries' crust, leaving them soggy and limp.
Blot as much moisture as possible from the fries, and heat your oven to 400°F. Very lightly oil a baking sheet and heat the fries for five minutes, check them, and heat in five minute increments until they're crisped to your liking.
When it comes to the actual cooking, you want to fry the french fries twice. The first round is at a lower temperature to cook the inside of the potato and the second time you'll use a higher temperature to make the fries golden brown and crispy. You can use a home deep-fryer or just heat the oil in a Dutch oven.
