Bam’s Three Cheese Potatoes Au Gratin

If there’s something I know my family will always eat it’s cheese. When I used to make Au Gratin potatoes I used only cheddar but I learned they like it better if there’s a blend of cheeses. I usually keep a couple of blocks of hard cheese in the freezer but I’m using finely shredded cheese for this recipe.


Bam’s Three Cheese Potatoes Au Gratin


  • 4 – 5 medium Russet potatoes
  • 1 cup heavy cream
  • ½ cup milk
  • 1 1/2 tablespoons flour
  • 1 clove of garlic, minced very fine
  • 1/2 teaspoon salt
  • 1/2 teaspoon pepper (or to taste)
  • 2 tablespoons butter (for sauce) + 2 teaspoons butter (for Panko topping)
  • Butter to coat baking dish
  • 1 cup cheddar cheese
  • 1/2 cup Monterey Jack cheese
  • 1/2 cup Panko bread crumbs


  1. Preheat oven to 400°F
  2. Scrub, but do not peel potatoes.
  3. Slice about 1/4” thick
  4. In a nonreactive saucepan melt 2 tablespoons of butter.
  5. Stir in the flour and cook for about 2 minutes.
  6. Beat together the cream and milk, until well combined.
  7. Add cream mixture to the flour mixture, whisking constantly, over low heat until liquid is slightly thick and coats the back of a spoon – about 4 – 6 minutes.
  8. Remove from heat.
  9. Toss sliced potatoes with garlic, salt, and pepper.


  10. In the prepared dish, put one layer of potatoes.   *You can see the 9×13 pan I used is too big. I usually make these potatoes in a large, oven-proof bowl and I’m going back to it!
  11. Pour some of the cream mixture over the potatoes.
  12. Continue to layer potatoes and then cream mixture, ending with the cream mixture.
  13. Cover and bake for 20 minutes.
  14. Uncover and bake until potatoes are starting to brown on top – about 40 minutes.
  15. Melt 2 teaspoons of butter and mix with Panko breadcrumbs.
  16. Cover top of potato mixture with cheeses.
  17. Sprinkle buttered breadcrumbs over potatoes and bake until breadcrumbs are browned and cheese is bubbly – about 10 minutes.
