  • 2.5 pounds of russet potatoes
  • 1 large yellow onion
  • 1 cup milk
  • 1 cup heavy cream
  • 3/4 cup flour
  • 1 1/2 teaspoons of salt
  • 1 1/2 teaspoons of pepper
  • 1 cup sour cream
  • 5 cups grated cheddar cheese (divided)


Rinse and scrub about potatoes until clean.

Prepare a large bowl by filling with cold water and a couple of teaspoons of salt. Set aside.

Cut potatoes in quarters along the length of the potato. Cut out any undesirable spots. Using a mandolin or the quicker and easier food processor, slice potatoes thinly. Place slices into cold salt water after each potato to prevent browning. Slice yellow onion thinly and place into a very large separate bowl.

Preheat oven to 350F.

Pour milk and heavy whipping cream into a medium bowl. Whisk flour into cream mixture. Add salt and pepper and whisk again. Drain water from potatoes.

Next, place sliced potatoes, cream mixture. Add sour cream and 3 cups of grated cheddar cheese into the large bowl with onions. Using hands, combine all of these ingredients very well.

Prepare baking dish (size 9 x 13 inches or comparable) by spraying with non-stick spray or smearing well with butter.

Place a layer of potato mixture into baking dish. Then, from the remaining 2 cups of cheddar, place a layer of cheddar cheese. Make about 3 layers total with cheese between each layer then pour any remaining cream mixture over potatoes.

Finally, layer top with remaining cheese. Loosely cover potatoes with foil for the first 1-1/2 hours of baking so the top layer doesn't over bake. Remove foil after 1 1/2 hours. Bake for about two hours total or until a fork poked into middle of potatoes comes out easily.

It's a good idea to put a baking sheet on the oven shelf underneath your scalloped potatoes in case they overflow.

For a fancier flavor, you can add some Gruyere or Comte cheeses in place of some of the cheddar, 1/4 cup of white wine in place of 1/4 cup of the milk, or add freshly chopped herbs or ham.

Serve while steamy hot.
