  • 4 large russet potatoes, peeled and thinly sliced


  • 3 tablespoons butter
  • 1 small yellow onion, diced
  • 3 tablespoons all-purpose flour
  • 1 cup (245 g) half-and-half
  • ½ cup (123 g) whole milk
  • ¼ teaspoon kosher salt
  • ¼ teaspoon black pepper
  • 1 teaspoon garlic powder
  • ½ teaspoon Worcestershire sauce
  • ½ teaspoon onion powder
  • ¼ teaspoon paprika


  • cups cooked ham, diced
  • ¾ cup (85g) Cheddar cheese, grated
  • ¾ cup (85g) Monterey Jack cheese, grated


  • Preheat the oven to 375°F and grease a 9x13 baking dish.
  • Wash and dry your potatoes and then slice using a mandoline. If your potatoes are very large (like a bakers potato), you can cut them in half lengthwise.
  • Set potatoes aside while preparing the sauce, which takes about 10 minutes. 
  • Melt butter in a large skillet over medium heat. Add onion; cook and stir until starting to soften, 3 to 4 minutes. Sprinkle flour over onion and whisk together. Cook until golden brown, about 2 minutes. 
  • Stir in half-and-half and milk; whisk until thickened, 3 to 4 minutes more.
  • Remove sauce from the heat and season with salt and pepper, garlic powder, Worcestershire sauce, onion powder, and paprika.

When Ready to Assemble

  • Place half the sliced potatoes into a prepared baking dish; top with half the chopped ham, 1/2 the Cheddar cheese and 1/2 the Monterey Jack cheese. 
  • Pour in half the sauce from the skillet. 
  • Repeat layering the remaining potatoes. Add the rest of the ham and then pour over the rest of the sauce. Cover with remaining cheeses.
  • Cover with aluminum foil and bake in the preheated oven for 40 minutes.
  • Remove the foil and bake until the cheese on top is golden and sauce is bubbling, 20 to 30 minutes more.
