Creamy Scalloped Potato Bake - cooking recipe

Ingredients

4 large baking potatoes, peeled & sliced
1 1/2 cups cheddar cheese, grated
1 yellow onion, sliced
1 (15 ounce) jar bertolli alfredo sauce (or any brand of your choice)
1 (12 ounce) can Spam, cubed (or ham or bacon)
2 tablespoons butter
2 tablespoons olive oil

Preparation

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