You can reuse the oil after deep frying potatoes.
The oil that you deep fry potatoes in can be reused several times before it needs replaced.
I reuse my cooking oil to deep fry my potatoes for around 4 to 6 months before I change it out depending on how often I deep fry potatoes.
Deep frying potatoes takes around 4 to 8 minutes until they are fully cooked and ready to eat after you let the oil drip off.
Deep fried potatoes are bad for you in excess because of the oil that the deep fried potatoes are cooked in but it's okay to eat deep fried potatoes in moderation.
After deep frying potatoes I let the oil drip off the potatoes by hanging the deep fryer basket up above the oil and then after the potatoes cooled off I allow them to drip onto a paper towel.
I then take another paper towel and press the oil further out of the potatoes which makes the deep fried potatoes more healthy.
Any deep fried food can be bad in excess but in moderation the deep fried food including deep fried potatoes is okay.
Deep frying frozen potatoes takes between 5 to 10 minutes depending on how you like your fries or frozen potatoes to be cooked.
When I deep fry frozen potatoes or deep fry frozen french fries I preheat the oil in the deep fryer while preparing the frozen potatoes or french fries.
Then I place the frozen potatoes or frozen french fries into the deep fryer basket.
When putting the frozen potatoes or frozen french fries into the hot oil make sure to slowly lower the basket of frozen fries or frozen potatoes into the hot oil because putting the frozen potatoes or frozen fries into the hot oil too fast can cause the oil to splash back and cause a fire.
Keep an eye on the frozen potatoes in the deep fryer because sometimes it only takes 4 to 5 minutes to fry the potatoes if you're only frying a little bit of them.
The more potatoes you're frying the longer it takes to cook them.
But it should not take any longer than 10 minutes to deep fry the frozen potatoes.
