  1. Preheat oven to 350 degrees F (175 degrees C).
  2. Lightly grease 9x13 inch baking dish. Arrange potatoes over the bottom of the dish, and set aside.
  3. Melt 1 tablespoon butter in a saucepan over medium heat. Add the garlic and onion; cook and stir until the onion is transparent, about 5 minutes. Stir in 3 tablespoons butter until melted. Sprinkle the flour, salt, and pepper over the onion mixture. Cook and stir until mixture bubbles and thickens, about 2 minutes. Continue to stir the flour mixture while gradually pouring in the milk and buttermilk, and return the mixture to boiling. Stir in 3/4 cup Parmesan cheese; cook for 2 minutes until melted, and mixture is smooth. Pour the mixture over the potatoes in the baking dish, stirring to coat evenly.
  4. Bake in preheated oven for 1/2 hour, and stir. Bake 1/2 hour longer, stir the potato mixture again, and sprinkle with remaining 1/4 cup Parmesan cheese. Bake for 20 minutes more.

I don't know what to think about this recipe. It didn't have tons of flavor and my potatoes basically soaked up just about all of the liquid. However, they were filling, something different, and...

Soooo good-buttermilk makes the difference! Occasionally I add a little Havarti cheese with dill and/or caraway cheese. Leftovers I turn into chunky potato soup. I make this often, thanks!

GREAT recipe! I found this recipe while trying to use up some buttermilk. I did not peel my potatoes as I used small new potatoes. I just sliced and added to the pan. The mixture of the butt...

Love, love, love them! I ended up using only 10 small potatoes & 1 1/3c of shredded parm because that's what I had on hand & needed to use up. I kept all other measurements as written. Just fabu...

I'm giving 5 stars even though mine didn't come out as they should. My potatoes must have been too new because they would not soften for me no matter how much I baked them. Despite crunchy and...
