4 tablespoons butter
4 tablespoons flour
2 tablespoons dried minced onion
1 teaspoon salt
½ teaspoon pepper
3 ½ cups whole milk

Preheat oven to 350˚F. Melt the butter in a pan. Stir in the flour. Cook for 2 minutes, stirring constantly.
Slowly whisk in the milk until the clumps of flour have dissolved.
Add the salt, black pepper, dried minced onion, and garlic salt. Bring to a boil while stirring. Cook and stir for 2 minutes or until thickened.
Remove from heat. Stir in cheddar cheese until melted.
Arrange ½ of the potatoes in a greased baking dish. Top with half of the sauce. Repeat with a second layer. Dot with butter.
Cover and bake for 30 minutes. Uncover and continue baking for 50-60 minutes, until tender. For added color, brown under broiler for 1-2 minutes, if desired. Garnish with parsley.
