Why do you want to reheat them?

Leftover potato dauphinoise

There are a few reasons why you might have leftover dauphinoise potatoes.

Maybe you made too much, or perhaps you had some for dinner, and now you want to enjoy them for lunch the next day.

Leftover dauphinoise potatoes can be a little bit of a challenge to reheat. You don’t want them to get dry and crusty, but you also don’t want them cold and gooey in the middle.

Preparing them in advance

You might also cook them days in advance. You can reheat them when you’re ready to eat.

Refrigerated dauphinoise potatoes can last up to 5 days, so make sure you eat them during that time frame.

Reheating using an oven

This is the most common technique of reheating dauphinoise potatoes because it maintains the potatoes’ texture and flavor.

When reheating frozen potatoes in the oven, leave them to thaw overnight in the fridge first. This will ensure that they can be quickly rewarmed.

Here are the steps of reheating the dish using the oven:

  1. Preheat the oven to 350F before you do anything else.
  2. Place the potatoes in an oven-safe dish. Cover the dish with aluminum foil so that you can trap heat inside.
  3. Place the dauphinoise potatoes inside the oven and let them reheat for 20-25 minutes on the middle rack.
  4. If you want the dauphinoise potatoes to have a crispy outside, take off the foil paper from the bowl, test potatoes for tenderness, and bake without the tin foil for 5-10 minutes, or until golden and crispy.
  5. Remove the dauphinoise potatoes from the oven.
  6. Place them on a plate, and serve them while hot to enjoy the best flavors.

Using a stove

When using this method to reheat frozen dauphinoise potatoes, thaw them overnight for the best results.

Here are the steps of reheating the dish using the stove:

  1. Put your potatoes in a pot, and place the pot on a stove. Turned the stove to medium to low heat so that the potatoes do not burn.
  2. Cover the pot with a lid so that the heat can circulate to the dauphinoise potatoes.
  3. Allow the potatoes to reheat for 15-20 minutes. Make sure you do not scald the bottom of the potatoes.
  4. When done, remove them from the pot and place them on a plate.
  5. Serve them while hot to enjoy the best flavors.

Using a microwave

This is the fastest and most convenient method of reheating dauphinoise potatoes.

You don’t have to worry about thawing the dauphinoise potatoes overnight in the refrigerator. You can directly reheat the potatoes from the frozen state with the microwave.

You need to know that reheating using the microwave doesn’t brown them.

Here are the steps of reheating the dish using a microwave:

  1. Place the dauphinoise potatoes in a microwave-safe dish and cover the bowl using plastic wrap.
  2. Leave one side of the bowl slightly open. This will help to enable heat to freely circulate within the dauphinoise potatoes. Heating the food unevenly can leave cool pockets where bacteria can thrive.
  3. Place the dauphinoise potatoes in the microwave oven and let them reheat on high heat for about 3 minutes.
  4. Check on the progress of the dauphinoise potatoes. The internal temperature should read above 165 degrees If they are still not hot, reheat them again for another 3 minutes.
  5. Serve the dauphinoise potatoes while hot for the best results.
