Prepare the Potatoes: Preheat oven to 425°F (220°C). Wash and scrub potatoes thoroughly. Pierce each potato several times with a fork. Rub potatoes with olive oil and sprinkle with salt.
Bake the Potatoes: Place potatoes directly on the oven rack or on a baking sheet. Bake for 45-60 minutes, or until a fork easily pierces the flesh.
Cook the Bacon: While potatoes are baking, cook the bacon until crispy. You can bake it alongside the potatoes on a separate baking sheet (lined with parchment paper for easy cleanup), fry it in a skillet, or use an air fryer. Once cooked, drain on paper towels and crumble.
Prepare Toppings: While the potatoes and bacon are cooking, prepare any desired toppings (chop green onions, shred cheese, etc.).
Assemble the Loaded Potatoes: Once the potatoes are cooked, remove them from the oven. Carefully cut a slit lengthwise in the top of each potato and fluff the inside with a fork.
Add Toppings: Top each potato with butter (if desired), shredded cheese, crumbled bacon, and any other toppings you like.
Serve: Serve immediately while the cheese is melted and the potatoes are hot.
