Ingredients

Sauce and Topping

  • 1/2 cup ranch dressing
  • 1/2 cup mayonnaise
  • 1/2 cup whole milk
  • 3 garlic cloves, minced
  • 2 cups medium cheddar cheese, shredded (8 oz), divided
  • 1/4 cup chives, finely chopped (for garnish)

Potatoes

  • 3 lbs russet potatoes (about 5 large potatoes), peeled and thinly sliced less than 1/8″ thick

Instructions

  1. Preheat Oven: Preheat your oven to 375˚F and position the rack in the center. Prepare a 9×13 inch casserole dish by buttering it thoroughly to prevent sticking.
  2. Make the Sauce and Combine: In a large mixing bowl, combine the ranch dressing, mayonnaise, whole milk, minced garlic, and 1 cup of shredded cheddar cheese. Stir well. Add the thinly sliced potatoes to the bowl and toss gently until each slice is evenly coated with the creamy ranch cheese sauce.
  3. Assemble the Casserole: Spread the coated potato slices evenly in the prepared casserole dish, patting them down so the layers are compact and even. Sprinkle the remaining 1 cup of cheddar cheese evenly over the top of the potatoes.
  4. Bake Covered: Cover the casserole dish tightly with aluminum foil and bake in the preheated oven for 65-75 minutes, or until the potatoes are tender when pierced with a knife.
  5. Bake Uncovered and Broil: After the potatoes are tender, remove the foil and bake uncovered for an additional 5 minutes to help set the cheese. Then, switch your oven to broil and broil the potatoes for 2-3 minutes on high heat to achieve a lightly browned, bubbly cheese crust. Keep a close eye to avoid burning.
  6. Rest and Garnish: Remove the casserole from the oven and allow it to rest for 10-15 minutes. This resting time helps the dish to set and makes serving easier. Finally, sprinkle the finely chopped chives over the top for a fresh, flavorful garnish before serving.

Notes

  • Peeling and slicing the potatoes thinly (less than 1/8 inch) ensures they cook evenly and become tender within the baking time.
  • For a sharper flavor, consider using sharp cheddar cheese instead of medium.
  • If you prefer a lighter option, substitute mayonnaise with Greek yogurt.
  • Broiling at the end is crucial to get that perfect golden-brown cheesy crust.
  • Resting the dish before serving helps the sauce thicken and the potatoes hold their shape.
