Instructions

  • Preheat oven to 400°F (200°C). Spray a 14x11.5x2.25 inch baking dish with non-stick spray
  • Peel potatoes and slice 1/8 inch thick. Uniform slices ensure even cooking
  • In a large pan, melt butter over low heat. Add onions and garlic; sauté 4–5 minutes until soft
  • Sprinkle flour over the mixture. Cook 2 minutes to remove raw flour taste
