Crock Pot Au gratin Potatoes

In a skillet, melt the butter and flour over medium low heat, whisking constantly.

SLOWLY pour the milk in while continuing to whisk.

Stir in the salt and pepper.

Remove from heat and stir in the cheese.

Slice the potatoes in 1/4 inch slices and layer in the bottom of the crock pot, alternating them with slices of onion.

Pour the cheese mixture over the potatoes and shake the crock pot to let it sink into all the crevices.

Place a layer of paper towels over the top (under the lid) and cook on high for 3-4 hours.
