How to Make Bill Knapp's Au Gratin Potatoes

  1. Preheat oven to 350°F (175°C).
  2. Peel and thinly slice 3 lbs russet potatoes.
  3. Melt 1/2 cup (1 stick) unsalted butter in a large saucepan over medium heat.
  4. Whisk in 1/4 cup all-purpose flour and cook for 1-2 minutes, stirring constantly, until a smooth paste forms (roux).
  5. Gradually whisk in 4 cups whole milk, stirring continuously until the sauce thickens and comes to a simmer.
  6. Reduce heat to low. Stir in 1 teaspoon salt, 1/2 teaspoon black pepper, 1/4 teaspoon garlic powder, 1/2 teaspoon onion powder, and 2 cups shredded sharp cheddar cheese. Cook until the cheese is melted and the sauce is smooth.
  7. Gently stir in the sliced potatoes, ensuring they are evenly coated in the cheese sauce.
  8. Pour the potato mixture into a greased 9x13 inch casserole dish.
  9. Bake uncovered for 25-30 minutes, or until the top is golden brown and bubbly. For extra crunch, top with 1/2 cup soft bread crumbs during the last 10 minutes of baking.
