Cheesy Ranch Potato Bake

4 lbs. russet potatoes, cut into 1/4 inch cubes
2 teaspoons chili powder
1 teaspoon salt
1/2 teaspoon ground black pepper
6 Tablespoons butter, cubed
1 (8 oz) pkg. shredded colby Monterey Jack cheese blend
1 (8 oz) bottle Ranch dressing

Preheat oven to 400. Lightly grease a 9x13 baking dish.

Place the potatoes in the baking dish. Season with chili powder, salt, and pepper. Evenly distribute the butter over the potatoes. (I did not use nearly as much butter as it called for.)

Cover the dish with aluminum foil, and bake 1 hr. in the preheated oven, until potatoes are tender. Remove from oven, and mix in the cheese and Ranch dressing. Continue cooking 10 minutes, or until cheese is melted and bubbly.
