Scalloped Potatoes

By Maverick19

Ingredients

• 3 lbs potatoes, thinly sliced
• 1/2 onion, thinly sliced
• 9 Tbsp all-purpose flour, divided
• 6 Tbsp butter, diced and divided
• salt and ground black pepper to taste
• 3 cups whole milk, or as needed

Preparation

Step 1

Preheat oven to 375 degrees and grease a 13x9 baking dish

1. Spread about 1/3 of the potato slices into the bottom of the prepared baking dish. Top with about 1/3 of the onion slices. Sprinkle 3 Tbsp flour over the potato and onion. Arrange 2 Tbsp butter atop the flour. Season the entire layer with salt and pepper. Repeat layering twice more.
2. Heat milk in a saucepan until warm. Pour enough warm milk over the mixture in the baking dish so the top of the liquid is level with the final layer of potatoes.
3. Bake in preheated oven until potatoes are tender, 45-60 minutes.
