15 smallish potatoes
3 T. butter
1 1/2 tsp seasoning salt
1/2 tsp garlic powder
2 T parmesan cheese
Wash the potatoes without peeling and cut them in half. Melt the butter and mix with spices and parmesan. Pour onto a cookie sheet and spread with a brush. Place the potatoes cut side down, brush the tops with the butter/parmesan mix around them, and bake for 40 minutes at 400 degrees.
15 potatoes exactly fits my cookie sheets. Adjust as necessary. You can be generous with the butter, and add more parmesan if desired.
