  • 8 russet potatoes washed, peeled, and sliced 1/8 of an inch thick
  • 1 teaspoon onion powder
  • 5 tablespoons salted butter melted
  • 3 tablespoons olive oil
  • ½ teaspoon salt
  • ½ teaspoon ground black pepper
  • 1 tablespoon dried chives
  • 3 strips bacon cooked and chopped


  • Preheat the oven to 375°F.
  • In a small mixing bowl combine melted butter, oil, onion powder, salt, pepper, and dried chives. Whisk to combine.
  • Brush the bottom and sides of a 9 to 10-inch baking dish with some of the butter and oil mixture. Set aside.
  • Place the sliced potatoes vertically in the baking dish. Sprinkle the potatoes with salt and pepper. Brush the remaining butter and oil mixture over the tops of the potatoes.
  • Place the baking dish in the oven and bake for 1 hour and 15 minutes uncovered.
  • While the potatoes are baking in the oven fry the bacon in a medium skillet over medium high heat until crisp. Drain the cooked bacon on a paper towel lined plate and then chop into small pieces.
  • Remove the potatoes from the oven and sprinkle the bacon over the top of the potatoes. Brush additional butter from the bottom of the pan over the top of the potatoes. Place back in the oven for an additional 15 minutes, or until the potatoes are crispy on the top and tender on the inside.
  • Remove from the oven and serve immediately.


TIP: If the potatoes are starting to dry out on the top during baking, brush some of the butter mixture from the bottom of the dish over the top of the potatoes to re-moisten. If they seem to be cooking too quickly, add some aluminum foil to make sure they cook thoroughly.
TIP: Add a dollop of sour cream and an extra sprinkle of chives on top when you are ready to serve these delicious potatoes.
