Step 1: Preparing and Baking the Potatoes (First Bake)
- Preheat your oven to 400°F (200°C). Thoroughly scrub the six large Russet potatoes under cool running water, removing any dirt or blemishes, and dry them completely.
 - Rub the outside of each potato with the 2 tablespoons of olive oil or vegetable shortening, then sprinkle them evenly with the 1 teaspoon of Kosher salt (for coating).
 - Pierce each potato deeply four to five times using a sharp fork or paring knife. Place the potatoes directly on the oven rack, or on a foil-lined baking sheet.
 - Bake for 50 to 75 minutes, or until the potatoes are tender when squeezed or easily pierced with a fork. Carefully remove the potatoes from the oven and let them cool on a wire rack for about 10 to 15 minutes.
 
Step 2: Creating the Potato Filling
- Reduce the oven temperature to 350°F (175°C). Use a sharp knife to slice off the top lengthwise (about 1/4 inch) of each cooled potato.
 - Carefully scoop out the potato flesh into a large mixing bowl, ensuring you leave a sturdy, intact border of about 1/4 inch of potato attached to the skin all around. Set the empty shells aside on a baking sheet.
 - Add the 4 tablespoons of softened butter, the 1/2 cup of whole milk or heavy cream, and the 1/2 cup of sour cream to the potato flesh. Using a hand mixer or potato masher, beat the mixture until light, fluffy, and smooth. Avoid overmixing.
 - Fold in 1 cup of the shredded sharp cheddar cheese, the 1 teaspoon of Kosher salt, the 1/2 teaspoon of black pepper, and half of the chopped fresh chives or green onions. Taste the mixture and adjust seasoning as needed.
 
Step 3: Filling and Second Bake
- Spoon the potato mixture generously back into the six empty potato shells, mounding the filling high above the shell rim.
 - Evenly sprinkle the remaining 1/2 cup of shredded sharp cheddar cheese over the top of the filled potatoes. If using, sprinkle a small pinch of paprika over the cheese.
 - Place the filled potatoes back into the preheated 350°F (175°C) oven. Bake for 15 to 25 minutes, or until the filling is heated through completely and the cheese on top is melted, bubbly, and lightly golden brown.
 - Remove the twice baked potatoes from the oven and allow them to rest for 5 minutes. Garnish the top of each potato with the remaining fresh chives or green onions immediately before serving hot.
 
Notes
For make-ahead convenience: Prepare the potatoes through Step 2 (Filling). Place them uncovered in the refrigerator for up to 2 days. When ready to bake, add 5-10 minutes to the Second Bake time to ensure they heat through completely.
