Scrub the potatoes and pierce with a fork. Lightly coat with olive oil and salt. Bake at 400°F for about 45 minutes or until cooked and tender.
Once the potatoes are cool enough to handle, cut a thin slice off the top of each potato. Scoop out the inside of the potato, leaving a thin shell.
Put the scooped out potato into a bowl and add in the French Onion Dip, cheddar cheese, chopped bacon, mayonnaise, green onions, and pepper. Mash and stir to combine.
Spoon mashed potato mix back into the baked shells. Sprinkle with remaining cheese. Bake potatoes at 300°F for 10-15 minutes until cheese in melted and potatoes are warmed.
