Cut the bacon into strips (lardons). Place in a cold pan, and turn the heat to medium. Let the fat render until the bacon is crisp. Remove, and drain on paper towel.
4 strips Thick-cut bacon
Preheat the oven to 375°F.
Line the potatoes on a baking sheet, and bake for 50 minutes to 1 hour until the potatoes are fork tender.
4 Russet potatoes
Remove the baked potatoes from the oven, and let them cool slightly. Cut the tops off the potatoes, and scoop out the inside flesh.
Add the scooped potato flesh to a large mixing bowl with the salted butter and sour cream. Using a potato masher, combine the mixture until it is mostly smooth.
¾ cup Sour cream, 2 tablespoon Salted butter
Fold the green onions, chopped bacon, and roasted garlic paste into the mashed potatoes. Season with salt and pepper.
4 strips Thick-cut bacon, 2 stalks Green onion, 1 head Roasted garlic, 1 teaspoon Kosher salt, 1 teaspoon White pepper
Transfer the potato filling to a large freezer bag. Remove the excess air from the bag, and seal. Cut off the tip of one corner of the bag, and pipe the potato mixture into the potato skins.
Place the filled potatoes in the oven on broil, until the tops of the potatoes are golden brown.
