reheat oven to 400°. Pat potatoes completely dry with paper towels. Poke potatoes all over with a fork, then rub with oil and sprinkle with salt. Place potatoes directly on oven racks and bake until potatoes are pierced easily with a fork, about 1 hour. Place on a large baking sheet and let cool until cool enough to handle.

Cutting lengthwise, cut a thin layer off the top of each potato. Scoop inside out of each potato leaving a ½” border. Place insides in a large bowl. Keep the potato tops and roast them on the tray as a snack!

To bowl with potatoes, add butter, milk, and sour cream and smash until butter is melted in and potatoes are mostly smooth, but with some chunks. Add 1 cup of cheese and green onions and stir until incorporated. Season with salt and pepper.

Fill baked potatoes with potato mixture and place on a large baking sheet. Top with remaining ½ cup of cheddar. Bake until cheese is melty and outside is crispy, 15 minutes.

Garnish with more green onions before serving.
