How to cook deliciously - Crock-Pot Au Gratin

1. Stage

In a medium sauce pan over medium heat, melt butter. Add flour and cook 1-2 minutes until no longer raw, whisking frequently. Add whole milk and whisk again. Bring to a simmer and let bubble until thickened slightly, 3-4 minutes. Season with garlic powder, salt, and pepper and remove from heat. Whisk in cheddar and 1/4 c parmesan and whisk until smooth.

2. Stage

Spray the bowl of your Crock-Pot with nonstick cooking spray. Add a small spoonful of cheese sauce on the bottom of Crock-Pot bowl. Create your first layer of sliced potatoes, overlapping them slightly, until a completer layer is formed. Spoon over more cheese sauce (about a 1/4 c) and sprinkle with about 2 tablespoons of the remaining parmesan. Continue layering until all potatoes, cheese sauce, and parmesan are used, ending on parmesan.

3. Stage

Place slow cooker on high and cook until potatoes are tender, 2 1/2 to 3 hours, checking halfway to make sure the potatoes aren’t burning. When finished, remove Crock-Pot insert if oven friendly and broil if desired. Garnish with parsley and serve.
