A healthy and Easy Homemade Scalloped Potatoes recipe that is made with less cheese and dairy than your typical dish and makes a wonderful Thanksgiving, Christmas, or Easter side dish recipe.
Place butter in a medium-sized saucepan over medium heat. Once butter has melted whisk in salt, pepper, garlic powder, and flour.
When a thick paste forms start adding in milk ½ cup at a time. Whisk until sauce begins to thicken before adding the next addition. This part takes about 5 minutes to completely incorporate the milk.
When all milk has been used and sauce is a gravy consistency, turn off the heat and stir in ¾ cup of the cheddar cheese.
Spray a 2 ½ qt. baking dish (or a 9 x 13 inch baking pan) with non-stick cooking spray. Layer half of the potatoes in the pan, then half of the onion and half of the cheddar cheese sauce. Repeat these layers.
Optional: If you would like your topping to be slightly crispy, turn on the broiler to High and cook for 2-3 more minutes. Make sure to watch the potatoes closely to prevent burning.
