1/4 cup butter
1 small onion, diced
1 Tb. flour
1/2 tsp. salt
1/2 tsp. pepper
2 cups milk
2 cups shredded cheddar cheese (sharp preferred)
1 Wash the potatoes, then peel and slice into 1/8” thick slices. You need about 4 cups of slices.
2 In a medium to large saucepan, melt the butter and cook the onion 2-3 minutes to tender.
3 Stir in the flour, salt, and pepper and cook until bubbly, stirring constantly.
