Kielbasa, Potato Gratin

4 tablespoons Butter
3 tablespoons Flour
2 cups Milk (heated)
1 tablespoon Dijon mustard
5 to 6 Potatoes (large)
1 large ring Kielbasa
1/3 cup bread crumbs
1/4 cup Parmesan cheese
1 cup Cheddar cheese
1 cup Monterey Jack cheese
Salt and Pepper Season to taste


Slice the potatoes in 1/4" slices and pre-boil them until 1/2 cooked.
Slice the kielbasa and set aside.
Melt 3 tablespoons of butter in a saucepan and stir in the flour.
While whisking, add the milk slowly and simmer for 5 minutes.
Reduce heat and add the mustard and slowly add all three cheeses.
Stir until melted. Add salt and pepper to taste.
Coat a rectangular dish (like one of those Corning dishes) with cooking spray or butter.
Layer the bottom of the dish with the potatoes.
Layer kielbasa on top of the potatoes.
Top with some of the sauce to lightly cover.
Repeat layers again with more potatoes, kielbasa and sauce.
Melt the last tablespoon of butter and mix with the breadcrumbs.
Top dish with the butter-breadcrumbs.
Bake at 350 degrees until brown and begins to bubble. About 40 minutes.
FYI - If it looks runny, the cheese will solidify as it cools. Enjoy!
