Preheat your oven to 400°F (200°C). Scrub the russet potatoes, dry them well, and prick each one a few times with a fork. Rub the skins with the olive oil and sprinkle with some of the kosher salt. Place the potatoes directly on the oven rack (you can place a foil-lined baking sheet on the rack below to catch drips). Bake for 50–60 minutes, until the skins are crisp and a fork slides easily into the center.
6 medium russet potatoes, 2 tablespoons olive oil, 1 teaspoon kosher salt
Remove the baked potatoes from the oven and let them cool on a wire rack for about 10–15 minutes, until they are still warm but cool enough to handle without burning your fingers.

While the potatoes bake or cool, cook the bacon in a skillet over medium heat until crisp. Transfer to a paper towel–lined plate to drain and cool, then crumble into small pieces. Alternatively, bake the bacon on a sheet pan at 400°F (200°C) for 15–18 minutes.
8 slices thick-cut bacon
Once the potatoes are cool enough to handle, slice each one lengthwise. Using a spoon, carefully scoop out most of the fluffy centers into a bowl, leaving about 1/4 inch of potato flesh attached to the skins so they stay sturdy. Set the scooped potato flesh aside for the filling.

Increase the oven temperature to 425°F (220°C). Arrange the hollowed-out potato skins, cut side up, on a parchment-lined baking sheet. Brush the insides and outsides of the skins with the melted butter, then sprinkle with garlic powder, onion powder, and a pinch of salt and pepper. Bake for 8–10 minutes, flip the skins, and bake another 5–8 minutes, until the shells are golden and crisp.

While the shells crisp, mash the reserved potato centers in a bowl. Add the milk, about half of the shredded cheddar cheese, and about half of the crumbled bacon. Season with additional salt and pepper to taste. Stir until the mixture is creamy but still thick, similar to the filling of twice-baked potatoes.

Remove the crisped potato shells from the oven and turn them cut side up. Spoon the potato filling evenly into each shell, gently mounding it. Top each filled skin with the remaining cheddar cheese and remaining crumbled bacon.

Return the filled potato skins to the oven and bake at 425°F (220°C) for 8–12 minutes, until the cheese is fully melted and bubbling and the edges are golden. For extra browned, toasty cheese, broil for 1–2 minutes at the end, watching closely so they don’t burn.

Let the loaded potato skins cool for about 5 minutes so they are easy to eat. Top with dollops of sour cream, a sprinkle of sliced green onions, and any optional toppings you like such as extra sour cream, chopped chives or parsley, pickled jalapeños, or a drizzle of hot sauce. Serve warm.
