Cut the potatoes in fourths and parboil them in a generous amount of water to cover.
Allow to cool, at least to the point you can handle them.
Grate them on the big holes of your grater.
Gently place them in a bowl.
Add the flour, salt, pepper, and onion and mix gently.
Let stand for about 5 minutes.
Heat the oil up to 355-360F
Use 1 ½ teaspoons potato mixture for each tot.
Shape the potato mixture gently until it is in the shape of a tater tot.
Fry, a few at a time, in the hot oil just until they are golden brown.
Drain on absorbent paper.
Be sure to chill them first. You can also cook them from frozen.
Spray lightly with olive oil.
Preheat air fryer to 400℉.
Place them in the air fryer basket in a single layer so that the sides don't touch.
Cook for about 10 minutes or until golden, gently turning after about 6 minutes.
