I use a 2 1/2 quart covered casserole dish for this. This will stick unless you have a great non-stick baking dish - I never grease the pan though because of all the fat that's already in this.
-
2
Preheat oven to 350.
-
3
Brown hamburger and onion.
-
4
Place a layer of sliced potatoes in casserole dish, top with half of hamburger/onion mixture. Salt and pepper to taste (kind of depends on how salty your cheese sauce is - you can always salt it later if it needs it).
-
5
Repeat layering of potato slices and hamburger mixture (and salt and pepper if desired).
-
6
Make Cheese sauce:
-
7
Melt 3 T butter in saucepan over med-high heat.
-
8
Add 3 T flour, and the salt and pepper. Stir quickly to blend.
-
9
Add 2 cups milk; stir with whisk to incorporate butter/flour mixture.
-
10
Reduce heat, stir till thickened and bubbly.
-
11
Remove from heat and add shredded cheddar. Stir until cheese melts.
-
12
Pour cheese sauce over hamburger and potatoes in baking dish. Push potatoes around to let cheese sauce into all of the crevices so it's well coated.
-
13
Cover and place in oven. Bake for about 1 1/2 hours, till potatoes are tender and top is browned. I like to take off the lid for the last 20 minutes or so to brown the top a bit.

Even with the leanest ground beef, this can get little pools of grease on top - I just spoon these off. It doesn't mean the whole thing is greasy - just cheesy.

My family members consider generous amounts of ketchup a necessary addition to this dish. I like it fine by itself (ok, maybe a spot of ketchup on the side).
