Directions

• Add potatoes to a large pot of water and bring to a boil. Cook until the potatoes are soft, about 20 minutes.
• Meanwhile, place the bacon slices in a large skillet over medium heat, and cook until crisp. Remove to paper towels.
• Wipe out the skillet, return to stove, and pour in vegetable oil. Stir in mushrooms and onion, and cook until onion is soft and translucent.
• When the potatoes are done, drain water, and place potatoes in a large bowl. Mash in butter and ranch dressing. With a potato masher or electric mixer, continue to mash until the potatoes are smooth. Stir in the mushrooms, onions, and crumbled bacon.
