A quick dip in a countertop deep fryer will breathe new life into soggy fries. If you don't have one, roasting them in a hot oven will also do the trick. You can also throw the fries into a hot skillet on the stove top. Additionally, an air fryer will crisp up a smaller batch of fries in just a few minutes.
Revive and Repurpose * Re-Crisp: The most obvious solution is to try and salvage the fries' original glory. * * Oven: Preheat to 400°F (200°C). Spread soggy fries on a baking sheet and bake for 10-15 minutes, flipping halfway, until crispy again. ...
Heat a few tablespoons of the oil in a nonstick pan over medium heat just until it starts to shimmer. Think about covering the entire bottom of the skillet in oil, erring on the side of using more oil than less. The oil helps to “fry” the French fries a second time and get them extra crispy.
Cut them first, then coat with an oil/corn starch mix. IIRC it's a tablespoon of cornstarch per cup of oil. Microwave for 3-4 min, then fry.
The idea is simple and doesn't require a deep-fry, or really even that much oil: Heat a large, heavy-bottomed pan over medium-high heat; pour in a few tablespoons of oil; add your sad fries; cook, flipping once; and have happy fries again!
Instead, bake the food on high heat for ten to fifteen minutes. This reduces the amount of moisture that can enter the food, making it crispy again.
First, preheat the oven to 425 degrees. Then, spread your French fries out on a parchment-lined baking sheet, making sure none of them are touching (if they're too crowded, they won't get as crispy). Heat them in the oven for about eight to ten minutes, then give them a quick toss.
There's moisture naturally found in potatoes, and moisture is drawn to higher concentrations of salt. (This is a process called osmosis.) So, if you put the potatoes in a salt water bath, that will help draw out some of their moisture, resulting in crispier fries.
But if you must use them, make sure to punch holes for ventilation. Soggy and limp fries, to your diners, are as good as eating leftovers in the fridge. So, prepare fries that are worth leaving the house for.
Toss the fries with just enough oil to coat (about 1/2 teaspoon for a small order of fries; 1 teaspoon for a large order of fries). Spread them out into a single layer on the toaster oven's crisper tray. Cook for about 2 minutes, then flip the fries over with a pair of tongs and bake for another 1 to 2 minutes more.
Potatoes fresh out of the ground can have too high a water content resulting in soggy fries, so preference is for those that have been stored for a while. In the two-stage or two-bath method, the first bath, sometimes called blanching, is in hot fat (around 160 °C/320 °F) to cook the fries through.
If you have a lot of fries to reheat, work in batches to ensure they all reheat and crisp up evenly. Set the temperature and cook time: After placing the basket into the air fryer, select 325 degrees Fahrenheit for the temperature and 5 minutes for the cooking time. Keep in mind that thicker-cut fries may need longer.

And generally speaking, restaurants fry their french fries twice: once at a lower temperature to cook the inside of the fry, and then a second time at a higher temperature to brown the exterior.
Reheat Them in the Oven
Get your oven nice and hot, like 450 F. Now, and arrange your fries on a flat sheet pan in a single layer and give them a light spritz of cooking spray. Heat for 5 to 10 minutes, flipping once during heating.
The fries are limp because the fat isn't hot enough and/or they are not cooked long enough. Oil does need to be 375-400 F, and fry in batches.
Cook the fries in preheated oil
Add the frozen fries to the preheated oil. Fry for about 7 minutes until they float to the top and are golden in colour. Remove them from the oil with a slotted spoon and place them on paper towels or similar. Season with salt, while the fries are still hot, to make it stick better.
Our suppliers peel, cut, blanch and par fry quality potatoes before freezing them and shipping them to our restaurants, where they're prepared into the hot, crispy fries you know and love. We're quite strict about the potatoes we use.
The secret tips that make all the difference: 1. Serrated knife to cut the potatoes = rougher surface = crispier 2. Blanch in vinegar water = wash away surface sugar that causes fries to burn before turning crispy (awesome tip from the legendary Kenji Lopez-Alt "The Food Lab") 3. Double fry!
