Cheesy Potatoes

4 - 5 Lb new potatoes
1 medium onion, chopped

 Sauce
4 Tbsp butter
4 Tbsp flour
1 tsp salt
1/4 tsp pepper
2 C milk
2 or more C shredded sharp cheese
1/2 tsp worcestershire sauce

Boil new potatoes until tender, drain and let cool. Peel and cube, and place in bottom of a 9" x 13" baking dish.

Dice onion, and scatter over potatoes.

In a separate pan, melt butter over a medium burner. Whisk in flour to make a roux.  Gradually stir in milk to make a smooth white sauce, then add shredded cheese (more is better) and the Worcestershire sauce.  Blanket the sauce over the potato - onion mixture in baking dish.

Bake at 350 to 375 degrees for 40 - 50 minutes until turning golden brown on top.
