Once the potatoes have cooled to the touch, start making the filling.
Using a paring knife, cut the top ⅓ of the potato off. Repeat with all of the potatoes.
Remove the skin from all of the “caps” that you just removed, and transfer the flesh of the potatoes to a medium bowl. Discard the skins.
Using a small spoon, gently spoon the centers out of the potatoes, being careful not to scrape too much out (they will not hold their shape if you do this). Transfer the potato flesh into the bowl with the other reserved potato.
Arrange the potatoes, cut side up, back on the sheet.
If you have a ricer, rice the potato flesh into a large bowl. If not, add the flesh directly to the bowl. You will need to mash it more this way but it will still work great.
To the potatoes, add the goat cheese, ghee, 4 tablespoons of chives, all the bacon aside from 1 tablespoon, salt, and pepper. Mix to combine. Begin to add the broth or milk in 1 tablespoon increments until you reach a smooth consistency. Add in ¼ cup of the cheddar cheese and mix to combine.
Spoon the filling into each potato, gently pressing it into the potato skin and then piling it high. Repeat with the remaining potatoes, adding them back to the sheet. You may have a bit of extra filling.
Finish the potatoes with the remaining 1 tablespoon of chopped bacon and ¼ cup of cheese.
Transfer to the oven and bake for 15 minutes, until the tops are starting to bubble and are slightly golden. Finish with the remaining tablespoon of chives. Cool for 10 minutes before serving. Enjoy!
