Instructions

  1. Preheat oven to 350 degrees Fahrenheit.
  2. Grease 13x9 baking dish.
  3. Add butter and olive oil to frying pan on medium-high heat.
  4. When hot, add Spam and fry until slightly browned.
  5. Remove Spam from pan and add sliced onions (add more butter to pan if necessary); cook onions for 4 or 5 minutes until translucent.
  6. Slice potatoes (I used a mandoline set to 1/32).
  7. Layer in greased casserole dish: Potatoes, onions, Spam, cheddar, alfredo sauce (just drizzle on each layer, no need to pour - this is very rich!).
  8. Keep layering until you run out of ingredients.
  9. Cover with foil and bake for 2 hours.
