4 tablespoons cornstarch
1 teaspoon kosher salt
1/2 teaspoon fresh ground pepper
2 cups low-fat milk
2 cups shredded white cheddar

INSTRUCTIONS
Preheat oven to 350°.
In a large saucepan, melt the butter over low heat. Stir in the garlic and cook 1 minute. Whisk in the cornstarch, salt and pepper until smooth.
Gradually add the milk and bring to a boil. Cook the sauce stirring constantly until thickened, approximately 2-3 minutes.
Remove from heat and stir in 1 1/2 cups of the cheese until melted. Stir in the potatoes.
Transfer to a 2 quart baking dish coated with cooking spray. Sprinkle with the remaining cheese. Cover and bake 30 minutes. Uncover and bake an additional 30-45 minutes or until the potatoes are tender and the sauce is golden brown and bubbling.
Remove from the oven and allow to stand 5-10 minutes before serving.
