When I cook potatoes in oil I always end up using a ton of oil. It takes forever and then I am left with an unhealthy side. I realized that I could cut the potatoes up into the size and shape I want, toss them in a covered bowl or dish with a lid and toss them in the oil first. I then add my salt and seasoning spread the potatoes or other root veggies onto a baking sheet and bake them at 350 for about 25 minutes, depending upon how thick the pieces are. This uses less oil, cooks more evenly and seasons better. If you want them crispier, be sure to rotate the vegetable as they cook. The sides touching the pan are the ones that get the crispiest.
