Scrub potatoes and then slice into strips. You can peel the potatoes if you like. Soak potatoes in fresh water for 15 minutes. Then drain water and pat dry with a paper towel.
Add the oil, salt, pepper and garlic powder in the sliced potatoes in a bowl. Toss to coat
Place the trivet and the cooking basket with the sliced potato inside the pressure cooker inner stainless steel pot. Try to place the fries in a single layer. If needed, you can also cook the fries in batches.
Now place the crisplid on top of the inner pot using the handle on the crisplid. Plug the crisplid and lower the handle. (Make sure the pressure cooker is unplugged)
Set to 375°F (190°C) and cook potatoes for 10 minutes. Flip fries and continue cooking until crisp, about 10 minutes more. If you like the fries to be crispier, then toss and add 5 more minutes.
Remove the french fries into a serving plate and serve immediately with your favorite dipping sauce.
