How to Make Alfredo Potato Casserole

  1. Preheat oven to 400°F (200°C).
  2. In a medium bowl, whisk together 1 (16 ounce) jar Alfredo sauce and 1/4 cup milk until smooth.
  3. In a large bowl, combine 1 cup chopped cooked ham, 1 cup shredded Swiss cheese, and 1 cup frozen peas (or 1 cup chopped frozen spinach/broccoli). Mix well.
  4. Grease a 9x13 inch baking dish.
  5. Spread 3/4 cup of the Alfredo sauce mixture over the bottom of the dish.
  6. Layer half of 3 pounds thinly sliced potatoes over the sauce.
  7. Top with half of the ham and cheese mixture, then 3/4 cup of the remaining Alfredo sauce.
  8. Sprinkle with 3 tablespoons grated Parmesan cheese.
  9. Repeat layers with remaining potatoes, ham mixture, Alfredo sauce, and Parmesan cheese.
  10. Cover the baking dish with foil.
  11. Bake for 45 minutes.

  13. Remove foil and bake for another 15-20 minutes, or until the potatoes are tender and the top is golden brown and bubbly.

Chef's Tip for Extra Flavor

Chef's secret: layers of flavor make a dish truly memorable! Consider what a little extra something could bring – perhaps a touch of acidity like a good vinegar or citrus zest, a hint of smokiness from paprika, a bit of umami from mushrooms or soy sauce, or a sprinkle of toasted nuts for texture. Experiment and taste as you go!
