Preheat oven to 400° F and line a baking sheet with parchment paper.
Scrub potatoes and dry thoroughly. Pierce all sides of each potato with a fork.
3 lbs. baby Yukon potatoes
Bake potatoes directly on middle oven rack for 35-45 minutes, or until easily pierced through the middle with a knife. (*Baking time will depend on the size of your potatoes. Mine took 35 minutes.)
Allow the potatoes to cool on a wire rack for about 15 minutes, or until cool enough to handle.
Preheat broiler to 500° F or high.
Cut each potato in half and scoop out the middle, leaving a bit of potato in each skin. Save the potato fillings to use in another dish.
Using a basting brush, brush both sides of the potatoes with melted butter and sprinkle generously with sea salt.
3 tbsp unsalted butter, Course sea salt
Place potatoes skin side up on prepared baking sheet on the middle oven rack. Broil for 6-7 minutes or until butter starts to bubble and skins become crispy. Be sure to keep an eye on them so they don’t burn!
Fill each potato skin with a small spoonful of beef crumbles or taco meat and top with a sprinkle of shredded cheese. Broil for another 4-5 minutes, or until the cheese is melted and beginning to turn golden brown.
⅓ cup cooked beef crumbles, 1 cup shredded cheddar cheese
Top each potato with a few black olives, tomatoes, and green onions. Dollop with sour cream and salsa if desired. Serve warm.
¼ cup black olives, 1 Roma tomato, ¼ cup green onions, sour cream and salsa for topping
