Ham and Scalloped Potato Rollup

 I saw something with a potato rollup , it had a  beef and tomato sauce and the like so it really didn't sound like something my family would go for but I LOVED the concept. I decided to turn it into a cheesy ham and potato roll! 

I only got end pictures so I am posting this in conjunction with doing another version using this roll up so you can reference those photos if needed.

8 oz shredded mozzarella, divided

6 oz shredded parmesan (not green can), divided

2-3 medium potatoes, scrubbed and sliced thin (thin enough that you can slightly see through them, about 1/16 inch)

1/4-1/3 white onion, sliced the same thickness as the potatoes

1 cup sour cream

8 oz shredded cheddar, divided

1 1/2 cups diced ham

2-3 green onions, chopped (plus one for serving)

garlic salt and pepper 

(For Rollup pictures please see Bacon Cheeseburger Rollup)

Line a large baking sheet(12x16) with parchment paper and spray it with cooking spray (don't skip the parchment paper, it is difficult to roll properly with out this)

Evenly spread 6 oz oz the mozzarella and 6 oz of the parmesan cheese on the parchment paper, make sure it isn't spread too thin, the cheese will help hold the potatoes together.

Evenly layer the potato slices, overlapping slightly, over the cheese.

Lightly press down with a paper towel to absorb excess moisture, sprinkle with garlic salt and pepper.

Top evenly with remaining mozzarella and parmesan (you can add more cheese if you like!)  and about 3/4 of your thinly sliced onions.

Bake at 350 for 30 minutes, until potatoes are soft and everything is bubbly and just starting to brown

Remove from the oven and immediately press down with a flat spatula to help the potatoes press together even more.

Allow to cool for 10 minutes

While it is cooling, shred 8 oz extra sharp cheddar and mix 1 1/2 cups with 1 cup sour cream. Reserve the rest of the cheddar.

When the potatoes have cooled, spread the cheddar/sour cream mixture evenly over the potatoes. Sprinkle with the diced ham, the rest of the sliced onions and the chopped green onions. Season more to taste.

Starting at a short end gently pick up the parchment paper and peel it away as you roll the potatoes up loosely, when it is rolled, set it seam side down back on the parchment paper. 

Top with remaining cheddar and put back in the oven for 20-30 minutes 

Allow to set for 10 minutes, slice with a sharp knife, top with more green onions and serve!
