How to Reheat Potatoes

The potato is one of the most popular vegetables across the globe. According to the Idaho Potato Museum, potatoes are grown in all 50 states of the USA and in about 125 countries throughout the world. On average, Americans eat almost 124 pounds of potatoes per year while Germans eat nearly double that amount. With that much love for spuds, you cannot let them go to waste.

Around 400 °F in the oven for quality or air fryer for quick will get the job done for most dishes, but even the microwave for 2-3 minutes can work in a pinch. Here are some of the best ways to reheat this versatile vegetable.

Use your oven for dishes that need that low and slow treatment

Reheating food in the oven covers the bases for most potato dishes and tends to produce the best quality. While this takes a little longer it is worth the wait.

Roasted Potatoes

There are many different seasonings and styles to roasting potatoes, but at its base we have diced potatoes, covered them in oil, and sprinkled with herbs and spices of your choice. In an article from Consumerist, here’s how to get overall warm roasted potatoes with that bit of crunch:

  1. Preheat the oven to 400° F
  2. Spread out your potatoes in a non-stick sheet pan
  3. (Optional) You can also add a light but fresh sprinkle of herbs to freshen up those flavors originally roasted in)
  4. Cover them with a sheet of foil (this is key to avoid over drying)
  5. Bake for 10-15 minutes
  6. Remove the foil and cook for an additional 5 minutes

Baked Potatoes

Served alongside your favorite foods from ribeye to sockeye, or even when it’s the main event, the baked potato is one of our most beloved dining options. With some restaurants sporting plate-sized or larger potatoes, you do not want to miss out on a second chance at this meal. Here are some simple instructions to get that next bite:

  1. Preheat the oven to 350° F
  2. For a crispier skin, please the potato directly on the rack, or a non-stick sheet works well too
  3. Bake for 15-20 minutes

Mashed Potatoes

One of the key to reheating mashed potatoes is adding a little extra butter or cream (milk or half and half will do) to get that smooth creamy texture to return.

  1. Preheat the oven to 350° F
  2. Take out your casserole dish and give it 15-20 minutes to get to room temperature, or transfer to an oven-safe dish if using storage containers
  3. Once in the oven, bake for 15-20 minutes or until the potatoes are thoroughly heated
  4. After bringing them out of the oven, mix in some butter and/or cream to recreate that soft delicious texture

Scalloped or Au Gratin Potatoes

First, you must distinguish these are two different dishes. While they are similar in nature, they have a few distinctions. Both use round sliced potatoes, cream, and baked. However, the au gratin dish uses thinner sliced potatoes, includes cheese, and tends to have breadcrumbs on top creating a nice crispy top layer. While these distinctions matter for taste, the reheating method is the same and the longest of the most potato dishes, keeping it at a low temperature to not separate the cream. These instructions may vary depending on the portion size you are reheating,

  1. Preheat the oven 300-325 °F
  2. Like our mashed counterparts, take out your casserole dish and give it 15-20 minutes to get to room temperature, or transfer to an oven-safe dish if using storage containers
  3. Once in the oven, bake for 20-30 minutes for smaller portions, but you may need 60-90 minutes if reheating full trays

(Optional) If you have breadcrumbs and want to add that crunchy topping, sprinkle some on for the last 15 minutes of heating.

The air fryer will crisp up those fast-food favorites

In a 6-month period, Door Dash recorded over 4.4 million orders of french fries in 2019. Along with tater tots and hashbrowns, these deep-fried sides can get soggy quick sometimes just on the ride back home. Here’s how to freshen up those fried favorites:

  1. Set air fryer to 400 °F
  2. Place your fries (or other side) in the fryer directly or line with foil if preferred
  3. Cook for 1-2 minutes if recently cooked, or 3-4 minutes if coming out of the refrigerator

You can follow the same recipe for baked potatoes, especially to get those crispy skin textures. For roasted potatoes, lower the heat to 350 °F and extend the time to 3-5 minutes.

The microwave can save the day

The biggest risks when heating things in the microwave is uneven heating and over drying. To counteract this, for those casserole-like dishes form a circle in the middle (making a donut-like shape). For those potatoes with a skin on them (roasted, baked, fried), reduce the heat to 50% and place a damp paper towel over the item when heating to reduce over cooking. Any of these dishes can be reheated in the microwave for as little as 30 seconds or in some cases up to 1-3 minutes, depending on the item and serving size.

In the end, you have any number of methods to reheat your spuddy buddies, but it depends on the time and texture you’re looking for to choose one that works for you.
