Get 2 lbs of potatoes. Skin and cut into 1 inch pieces. If you like the skins, just leave them on and cut into pieces.
Place potatoes into large Ziploc bag.
Add your olive oil.
Add your Ranch packet. Also you can use this same guide to make any other flavors such as Italian or Blue Cheese shown here.
Seal Ziploc and shake vigorously until all potatoes are covered.
Place in oven safe bowl/pan and put in oven set at 400 degrees for an hour. May want to stir it up about halfway through to make sure all sides get cooked evenly.
Should look like this when done. I also added some parmesan cheese. You can play with seasonings and add whatever sounds good to you. Eat and enjoy!
