How to Reheat Mcdonalds Fries (7 Methods)

As much as we love fast food, reheating leftover meals can be quite challenging.

This is especially true when it comes to preserving the crispy texture of french fries from a place like McDonald’s.

In this blog post, we’ll provide seven methods on how to reheat McDonald’s fries.

How to Reheat Mcdonalds Fries

Method 1: Oven

The first method for reheating McDonald’s fries is by using an oven. Preheat your oven to 350°F and leave the fries in their original container without adding any extra oil. Depending on the quantity of the french fries, it usually takes around 10-15 minutes for them to be hot and crispy.

Pros: The oven helps restore the crispness and crunchiness in those fries without making them too soggy or greasy.

Cons: This method involves using a large amount of electricity compared to other methods and can also take longer than most alternatives.

Method 2: Air Fryer

Air fryers are convenient appliances that have taken over many kitchens recently because they allow people to enjoy crispy food without actually deep frying them. It makes sense that air fryers also work well with reheating McDonald’s fries.

  1. Preheat your air fryer at 375°F before placing your leftover fast food in its basket.
  2. Set a timer for around three minutes before checking if they have regained their crispiness or not.

Pros: Air-fried McDonald’s French Fries come out fresh without leaving behind soggy or oily leftovers.

Cons: Air fryers may be too bulky for those who live in smaller apartments since they take up some counter space

Method 3: Toaster Oven

Toaster ovens are great space-saving options apart from being multi-purpose units for baked goods or pizzas. It effectively works with other dishes including McDonalds’ fries.

  1. Simply place the fries in a single layer on the toaster oven’s baking sheet and let them reheat for around 10 minutes at 350°F.
  2. Turn them halfway through to ensure they are crispy on all sides.

Pros: The amount of energy that toaster ovens save make it one of the economical options for reheating frozen food.

Cons: It can be difficult to heat up large portions because most toaster ovens aren’t big enough to accommodate fries for more than few people.

Method 4: Microwave

For many people, the microwave is a go-to solution when it comes to reheating anything. And when it is done right, it can be an effective method for McDonald’s fries too. This method is best used when you’re in a rush or only have a small portion of leftover fries.

  1. To reheat fast food leftovers in microwaves, put some parchment paper on a microwave-safe dish before placing the fries there.
  2. Heat them using wide-opened container lid and set your time depending on quantity and wattage strength (between 20-30 seconds).

Pros: The production time with this method compared to other alternatives saves both time and effort.

Cons: Microwaves cannot create crispy results since they work by steaming instead than heating directly which means less crispy features than traditional methods

Method 5: Stovetop

Reheating McDonald’s French Fries on a stovetop may be slightly different from other methods due to involving an oil layer while cooking process starts over low heat until they are tender before moving up towards higher temperature level finishing off much-crispier coating throughout evenly within just six minutes.

You’ll make sure you’ve got fresh no-stick skillet frying potatoes rather than recycled leftovers, which could cause the history greasy sheen problem if some coatings remain from past usage as well as previous frying inside themselves might not necessarily accept any sort of additional searing afterward anymore.

Pros: The crisp state of those fries be restored to complement the flavor and also reduce the greasiness through slow frying actual raw potatoes.

Cons: Depending on how much oil you use, this method can leave you with even more greasy results than the original fries which would make it difficult to recreate a similar experience repeatedly

Method 6: Deep Fryer

Deep fryers may not fit perfectly with everyone’s kitchen, but they are fantastic for reheating McDonald’s Fries easily when you fold them in correct manner.

  1. Preheat your deep-fryer to 350°F before placing your fast-food fries back in for about 5-6 minutes, depending on how crispy you like them.
  2. Keep an eye on them during heating as their texture can change rapidly once heated thoroughly enough.

Pros: This method provides optimal results by being near identical to what was served originally at McDonald’s – crispy exterior and fluffy internal layers

Cons: Consuming extra oil adds calories onto an already high-fat meal which could cause heart health issues if consumed regularly.


There are many ways one should go about reheating McDonald’s French Fries. Methods like deep fryer or oven may provide maximum crispiness yet microwave or stovetop procedure can give a more comfortable touch that does not take excess time or fuel.

To summarize, microwaving is best for when all fails or you are out of time; toaster ovens gives out evenly crispy coating but limited in big portions; air frying is recommended if available due its option saves energy consumption costs especially if used regularly whereas using a stove brings out potato flavors without drying up their interiors rather nicely.

Lastly we have paragon traditional style deep fryer – perfect for precise control over temperature levels anytime required with some added risks from oily residue after frying so clear concern while adopting this method.

Whatever the technique used, reheat leftover fries provides a unique epitome of fulfilling meal-time appetite with less effort so people should experiment what works better for them than going straight into conventional oven everytime.
