Ingredients:
*cooking spray
*3 lbs. Yukon Gold potatoes
*2 Tablespoons butter
*1 yellow onion, diced
*5 cups cubed ham (pre-cooked--I find this in the meat section)
*1 1/2 cups fat free half and half
*1 1/2 cups heavy whipping cream
*1/4 cup flour
*ground black pepper
*1 cup grated 2% cheddar cheese
*1 cup grated Monterey Jack cheese
Directions:
1. Preheat oven to 350 degrees. Spray a deep, large baking dish with cooking spray (including the sides).
2. Heat butter in a large skillet. Add the onions and saute for several minutes until transparent. Add the ham and cook for 4 minutes until hot. Remove from the heat and set aside.
3. In a microwave-safe container, combine the half and half and heavy whipping cream. Microwave on high for 1 minute or until it's no longer cold. Whisk in the flour and ground black pepper to taste. Set aside.
4. Slice potatoes using a mandoline. (I use Pampered Chef's mandoline which used to be called the ultimate slice and grate. It makes this step so easy and fast.) The potatoes should be very thin--about 1/8 inch thick.
5. Mix the two cheeses together in a large bowl. Layer 1/3 of the potatoes on the bottom of the baking dish. Top with 1/3 of the onion/ham mixture. Top with 1/3 of the cheese. Top with 1/3 of the cream mixture. Repeat this 2 more times.
6. Cover with foil and bake for 45 minutes. Remove the foil and bake for 30-45 more minutes, until bubbly and hot all the way through.
