Wash and peel your russet potatoes and cut them into thin slices.
Lay them in a 9 x 9 inch baking pan that has been sprayed with non-stick cooking spray.
Prepare the sauce by combining plain Greek yogurt, butter, 2 cups cheddar cheese, and milk in a saucepan over medium heat. Stir continually until smooth.
Pour the sauce over the potatoes, and garnish with salt, pepper, and extra cheese.
Place in the oven and bake for 25-35 minutes (more or less, depending on thickness of the potatoes) or until the potatoes are soft .
Remove from oven and garnish with dried chives, if desired.
Notes
For this recipe, I used just regular russet potatoes. However, you could use sweet potatoes, red potatoes, Yukon gold potatoes, or potato fingerlings - any thing would work.
This is a great Thanksgiving side dish!
Try to cut all the potatoes the same width so that they cook evenly. The thinner you slice the potatoes, the less time it will take to cook. Start checking the potatoes after 25 minutes of cooking to see if they are done.
