Instructions
- Preheat oven to 400°F (204°C). Spray a 14 x 11½ x 2¼ inch baking dish with nonstick spray and set aside.

- Layer ⅓ of potatoes in the baking dish, top with ⅓ sour cream and ⅓ cheese sauce.
- Sprinkle with ⅓ Parmesan, ⅓ pepper jack, and ⅓ remaining cheddar.
- Repeat layers two more times, finishing with cheddar on top.
- Cover with foil and bake for 1½–2 hours, depending on potato thickness.
- Remove foil for last 15–20 minutes to brown cheese.
- Let sit 15 minutes before serving.
Notes
- Use a mandoline for evenly sliced potatoes to ensure even cooking.
- Can be assembled ahead and refrigerated before baking.
