potatoes, diced (peeled, not peeled, russet, reds, whatever)
salt & pepper (or whatever other seasoning you like, taco seasoning, garlic herb, etc)
ranch dressing, to taste
shredded cheese of your choice, to taste
Preheat oven to 400 degrees.
Place the diced potatoes in a baking dish. Dot with a few pieces of butter. Season with salt & pepper, or whatever other seasoning you like. Cover with aluminum foil, and bake for 50-60 minutes, until potatoes are fork tender.
Add ranch dressing & shredded cheese to taste. Cook in the oven for another 3-5 minutes, until cheese is melted & ranch is piping hot.
