Heat the vegetable oil or bacon fat in a large skillet over medium heat. Make sure the skillet is large enough to accommodate the potatoes in a single layer.
Cook the Onions:
Add the sliced onions to the hot skillet. Cook and stir occasionally until the onions become translucent and start to caramelize. This process usually takes about 5-7 minutes.
Add Potatoes:
Add the sliced potatoes to the skillet. Spread them out in an even layer to ensure they cook uniformly.
Seasoning:
Season the potatoes and onions with salt, pepper, and paprika if you’re using it. Adjust the seasoning according to your taste preferences.
Cook Until Golden Brown:
Allow the potatoes to cook without stirring for a few minutes until the bottom layer turns golden brown. Then, flip the potatoes to brown the other side. Repeat this process until all the
potatoes are crispy and golden.
Check for Doneness:
