Preheat the oven to 425°F.
Pat the potatoes dry and pierce each several times with a fork. Rub with olive oil and sprinkle with coarse salt.
Place the potatoes directly on the oven rack (with a sheet pan on the rack below) and bake for 50–60 minutes, until the skins are crisp and a knife slides in easily.
While the potatoes bake, prepare the toppings: warm the beans, steam the broccoli, cook the bacon, and set everything out in bowls.
Slice each potato open, fluff the insides with a fork, and add a little butter, salt, and pepper.
Let everyone load their potatoes with their favorite toppings.
