How to Make Scalloped Potatoes

Make sure to very thinly slice and peel the potatoes first!
Then, preheat your oven to 400 degrees F and grease a 9×13” baking dish with butter.
Then, arrange the peeled and sliced potatoes in about 3 layers in the baking dish.
Once the potatoes are arranged, make the sauce. Begin by melting the butter a 5-quart saucepan over medium heat.
Then add the onion and garlic and cook until the onions are soft, which takes about 5 minutes.
Next, stir in the flour, salt and pepper and cook for about 1 minute, or until the roux it just begins to brown.
Once the roux is lightly browned, whisk in the milk and heavy cream, and cook over medium heat until thickened (about 1-2 minutes). Taste and adjust salt and pepper as desired.
Then, pour the sauce over the potatoes in the baking dish.
