Wash and peel the potatoes. Cut them into quarters and place them in a large pot of cold water. Bring to a boil and cook until tender, about 20 minutes.
Drain the potatoes and transfer them to a mixing bowl. Mash until smooth and allow to cool slightly.
In a frying pan, cook the ground beef over medium heat until browned. Season with salt, pepper, garlic powder, and onion powder. Drain excess fat.
In the bowl with the mashed potatoes, add the cooked ground beef, crumbled bacon, ranch dressing, and shredded cheese. Mix until fully combined.
Use a spoon or scoop to form balls of the potato mixture, then roll them in your hands to create the keg shape.
In a separate bowl, set up a breading station with flour, beaten eggs, and breadcrumbs.
Roll each tater keg first in flour, then in the egg, and finally coat with breadcrumbs.
Heat oil in a deep fryer or large pot to 350°F (175°C). Fry the tater kegs in batches until golden brown, about 4-5 minutes, turning halfway through.
Remove the kegs from the oil and place them on a baking sheet lined with parchment paper to drain excess oil.
Serve hot with additional ranch dressing for dipping.
