Scalloped Ham and Potatoes

Scalloped Ham and Potatoes

3 lbs. russet potatoes, washed
2 Tbsp. olive oil
1 onion, diced
3 c. diced ham
3 c. half-and-half
¼ c. flour
2 c. grated white cheddar
pepper to taste

Preheat oven to 350.  Butter a large casserole dish.

Peel and thinly slice potatoes.  Boil for about 7 minutes to help take the bite out.  (You can skip this step, but sometimes when I make gratin my potatoes stay a little crunchy and this helps with that.)  In a large skillet, heat olive oil and cook onion until tender.  Add cubed ham and cook until heated through.  Set aside.

Microwave half-and-half for a minute or so, until no longer cold.  In a small bowl, combine flour with a little of the milk to make a slurry and whisk into remaining milk.  (Helps with clumps to do it this way.)  Add pepper to taste.  No need to add salt since ham is already salty.

Layer ⅓ of potatoes in casserole dish.  Sprinkle with ⅓ ham mixture, then ⅓ cheese.  Pour ⅓ milk mixture on top.  Repeat two more times, ending with cheese.

Cover and bake for 40 minutes.  Remove foil and bake an additional 20 minutes, or until bubbly.
