Cheesy Potatoes Au Gratin

Ingredients

• 3 lb. red potatoes, scrubbed and cut into 1/4 inch slices
• 4 T. unsalted butter
• 1/4 c. all-purpose flour
• 1 t. kosher salt
• 1/2 t. onion powder
• 1/2 t. fine ground black pepper
• 2 c. 2% milk
• 12 oz. Colby-Jack cheese, shredded (divided)

Steps

1. Preheat oven to 400 degrees. Butter a 1 1/2 qt. casserole dish. Set aside.
2. Scrub and cut potatoes into 1/4 inch slices. Place in a large bowl of cold water.
3. In a medium saucepan over medium heat, melt butter. Add flour. Whisk to combine and cook for 2 minutes. Add spices and milk. Whisk to combine. Cook until mixture begins to thicken. Add 8 oz. cheese and stir to combine. Once cheese is melted and smooth, add about 1 c. to casserole dish.
4. Drain and rinse potatoes. Create a layer of potato slices on top of the cheese. Add 1 c. cheese sauce over the top of potato slices. Repeat until all potato slices are gone or you reach 1/2 inch from the top of the dish. Sprinkle remaining cheese over top of casserole.
5. Spray aluminum foil with non-stick spray and lay sprayed side down on the casserole. Bake for 75-90 minutes or until potatoes are tender. Uncover and place under the broiler for 2-3 minutes or until the cheese is golden brown.
6. Allow to cool for 5 minutes. Serve.
