"I created this potato dish when I had leftover ingredients to use up. They give a little subtle twist to scalloped potatoes, and may make you want seconds! They also reheat well, that is if you have leftovers..."

  • Prep

  • Cook

  • Ready In

  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.


  • Tip
  • Aluminum foil can be used to keep food moist, cook it evenly, and make clean-up easier.

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!

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...
