What temperature do you reheat French fries in the oven?

For best results, allow the fries an hour to warm up to room temperature and preheat the oven to 400 degrees Fahrenheit. Cover the baking sheet with crumpled aluminum foil and arrange the fries in a single layer onto the baking sheet. The crumpled effect of the aluminum foil will texturize the baking sheet and expose more of the fries' surfaces to the oven's heat.

Lightly brush or spray the fries with cooking oil and bake for five to ten minutes. Remove the baking sheet from the oven with mitts, and set the hot fries onto a clean plate. If the fries are oily, place them onto a sheet or two of paper toweling to absorb the oil droplets.

How do you reheat French fries on the stove?

Adding additional oil isn't required, instead, rely on the residual oil in the cold fries. Place an un-oiled skillet on the stove and heat it on medium-high heat. Once the skillet is heated fully, add the French fries. Flip and stir continuously to prevent the fries from sticking to the skillet.

Continue stirring the fries for three to five minutes or until the desired temperature is reached. Remove the fries from the skillet and add salt or seasonings.

The time required to reheat the fries could vary based on the thickness and volume of the fries. Suppose you have a large batch of fries, reheat in small batches to prevent the fries from clumping together in the skillet.

How long do cooked French fries last in the fridge? In the freezer?

French fries will last three to five days in the refrigerator. Provided the fries are stored inside an airtight container or wrapped tightly in aluminum foil. Also, the fries should be wrapped and put in the refrigerator two hours after cooking for food safety purposes.

Suppose you are freezing cooked French fries; always freeze within two hours after preparing.  Wrap the fries in plastic wrap with aluminum foil around the plastic to prevent freezer burn, or place the fries in a freezer-safe airtight container. When properly wrapped, the fries will last 10 to 12 months in the freezer.

How do you make leftover french fries crispy?

The Food Network suggests removing the fries from the refrigerator for about an hour before heating to ensure the fries reheat evenly. To begin, place a non-stick frying pan on the stove with a few tablespoons of olive oil and a dash of salt.

Cover the bottom of the pan with oil and allow the oil to heat. Once the oil is hot, place the fries in a single layer in the pan, with enough space to not be crowded or stick to each other.

Once the fries are heated through, gently toss them to "refry" both sides for added crispiness. Consider adding spices, basil, chives, garlic, and sea salt are excellent pairings with French fries.

Remove the hot fries from the pan with a slotted spoon or metal tongs and place them on paper toweling to absorb the excess oil.  Sample one fry to see if they require additional salt. If so, add it while the fries are still hot from the pan.

Additional thoughts

Reheating and repurposing foods are great for diminishing food waste and saving your hard-earned money. If you don't have the interest or time to reheat the fries, you could always repurpose them by adding bacon, cheese and broiling them until the cheese is melted. Otherwise, you could make classic poutine, adding cheese and gravy, great for a hearty snack or side!

Generally, reheating fries in the oven is considered the best method for enhancing flavor and reducing sogginess. However, time and resources don't always allow for this option. If you are in a hurry, consider microwaving the French fries to save time.
