Step 1

For the potatoes: Preheat the oven to 400 degrees F. Rub the potatoes all over with the oil. Season the skins with salt and pepper and place on a baking sheet. Bake until tender inside, about 1 hour. Set aside until cool enough to handle, but still warm. Leave the oven on.

Step 2

For the yogurt mixture: While the potatoes are baking, in a medium bowl, stir together the yogurt, cilantro, dill, mint, parsley and scallions. Taste and season with salt and pepper. Set aside.

Step 3

For the filling: Slice each potato in half lengthwise. Use a spoon to gently hollow out each half, leaving about 1/4 inch of flesh around the border and bottom. Mash the potato flesh in a large bowl with a fork or potato masher. Add the melted butter, half of the cream or milk, 1 cup of the cheese blend, 1/2 cup of the yogurt mixture, and salt and pepper to taste. Reserve the rest of the yogurt mixture for serving. Mix to combine, adding more cream or milk to make smooth. Taste and season with salt and pepper if needed.

Step 4

Re-bake the potatoes: Line a baking sheet with parchment or nonstick aluminum foil. Place the hollowed-out potatoes on the prepared baking sheet. Using a large spoon, fill the recess of each potato with the filling. Top the potatoes with the remaining cheese. Bake until the tops begin to brown, 20 to 25 minutes. Serve with a dollop of the reserved yogurt mixture.
