Preheat the oven to 425.
All you need is: 1 envelope of onion soup mix, 4 potatoes, and 1/3 C of olive oil.
This is the soup mix I use. Chop up your potatoes and toss with the dry soup mix and olive oil.
Turn occasionally throughout the cook time. Cook for 35-40 minutes, or until tender and golden brown. Very Good!
