Step 1

Preheat the oven to 400 degrees F (200 degrees C).

Step 2

Lay out 4 squares of aluminum foil on the counter. Cut each potato in half lengthwise, and place onto a square of aluminum foil. Place 1/2 tablespoon of butter onto the cut side of each half, then season with garlic powder and salt. Close the potato halves together, and wrap tightly in the aluminum foil.

Step 3

Bake potatoes directly on the oven rack for 40 minutes, or until tender.
