Detailed Preparation Steps
- Perfect White Sauce Creation:
- Melt butter slowly to prevent browning. Cook flour until raw taste disappears. Add milk gradually while whisking. Keep temperature moderate. Watch for proper thickening.
- Onion Caramelization:
- Slice onions uniformly thin. Use medium-low heat consistently. Stir occasionally, not constantly. Look for golden-brown color. Takes about 20-25 minutes for perfection.
- Potato Preparation:
- Use mandoline for consistent thickness. Keep slices in cold water. Dry thoroughly before layering. Maintain even ⅛-inch thickness. Remove any green spots.
- Assembly Strategy:
- Start with thin layer of sauce. Overlap potato slices slightly. Season each layer individually. Distribute onions evenly. End with generous cheese topping.
- Baking Method:
- Cover with foil for first 35 minutes. Remove foil to allow browning. Test doneness with knife. Watch carefully during broiling. Let rest before serving.
