  • 3Tbsp butter
  • 1/4 yellow onionfinely diced
  • 3Tbsp all-purpose flour
  • 2cups milk
  • 1/4tsp pepper
  • 1pound potatoeswashed and thinly sliced (about 3 medium baking potatoes)
  • 1 1/2cups cooked cubed ham
  • 1cup grated sharp cheddar cheese
  • 1cup grated Monterey Jack cheese
  • chopped fresh parsley for garnishoptional
  1. Preheat oven to 375 degrees
  2. Add butter and minced onions to a large skillet over medium-low heat. Cook about 10 minutes until onions are soft and translucent.
  3. Meanwhile, slice the potatoes and cube the cooked ham.
  4. Sprinkle flour evenly over the onions and whisk. Continue cooking this mixture about 2-3 minutes until the flour is light brown.
  5. Slowly add milk whisking constantly to prevent lumps. Continue whisking until the mixture thickens which should be in about 3-4 minutes.
  6. Add pepper and a pinch of salt if desired, mix well and remove from the heat.
  7. Spray baking dish with non-stick cooking spray or grease with butter.
  8. Add half of the potatoes, top with half of the ham and sprinkle with 1/2 cup of both the Cheddar and Monterey Jack cheeses. Pour half of the sauce over the top. Add the rest of your potato slices, the rest of the ham, and cover with the remaining sauce. Top with the remaining cheeses.
  9. Cover the dish tightly with foil and bake for approximately 40-50 minutes. The thickness of the potato slices determines how long this will take. Remove the dish from the oven and pierce the potatoes with a fork. They are done when you can easily pierce them with a fork.
  10. When the potatoes are done, remove the foil and continue baking for an additional 20-30 minutes or until the sauce is bubbling and the cheese is browned.
  11. Remove from the oven and garnish with chopped parsley before serving.
