Wash and cut potatoes into ½ inch pieces. Chop onion, set aside.
Heat skillet over medium heat.
Add bacon fat (or butter) to skillet. Add potatoes to skillet, and cover.
Allow potatoes to fry for 20-25 minutes, stirring only every 5 minutes, no more often than that. At 10 minutes of frying, add the onion and seasonings.
When potatoes are nearlyfinished, remove lid and fry till desired crispyness. Serve with ranch dressing or ketchup, if desired.
Notes
I calculated the nutritional values using 1/8 of the total recipe. Use any spices you want: I like using Thyme, paprika, or garlic. Any kind of potatoes work, I normally use russets or reds. 3 lbs is about 6 large potatoes, or 8 cups of chopped potatoes.
