Au Gratin Potatoes

Potatoes are one of the greatest comfort foods, in my opinion at least.  And with this winter they are needed and what better than adding some cheese to a cream sauce to raise the comfort level.  After all, you'll burn off the extra calories by shivering when you leave the house.

Au Gratin Potatoes

6 medium sized potatoes, peeled and sliced in 1/4" slices
3 tbsp butter
3 tbsp flour
2 cups 2% milk
1/4 cup onions, minced
1/4 cup Parmesan cheese, grated
8 oz mild cheddar cheese, grated
Salt and freshly ground pepper to taste
1/2 tsp paprika, divided

Place half of the sliced potatoes in a greased casserole dish.  Top with minced onions, Parmesan cheese, some salt, pepper and 1/4 tsp of paprika. Cover with the remainder of the potatoes.  
In a medium sauce pan, melt the butter.  When melted, stir in the flour and let cook for 1 minute.  Add in 1/2 cup of the milk, stir and let it thicken.  Repeat adding in 1/2 cup at a time.  Add in the cheddar cheese and stir until it melts.  Pour over the potatoes.  Sprinkle some salt, freshly ground pepper and the remaining 1/4 tsp of paprika on top.  Place in a 350° oven for 90 minutes.
