  • ✅ Main Ingredients:
  • 4 large Yukon Gold or Russet potatoes peeled and thinly sliced
  • 2 cups shredded cheddar cheese or a mix of cheeses
  • 2 cups heavy cream or whole milk for a lighter version
  • 2 tbsp unsalted butter melted
  • 2 cloves garlic minced
  • 1 tsp salt

  • ✅ Optional Additions:

Instructions
 

  • 1️⃣ Preheat Oven & Prep Dish
  • Preheat your oven to 375°F (190°C).
  • Grease a 9x13-inch baking dish with butter or non-stick spray.
  • 2️⃣ Prepare the Potatoes
  • Peel and slice the potatoes thinly (about ⅛ inch thick).
  • Place the slices in a bowl of cold water for 10-15 minutes to remove excess starch. Drain and pat dry.
  • 3️⃣ Make the Creamy Sauce
  • In a medium saucepan, melt butter over medium heat. Add garlic and sauté until fragrant (1 minute).
  • Pour in the heavy cream, salt, black pepper, paprika, and thyme. Stir and simmer for 2-3 minutes.
  • 4️⃣ Layer the Casserole
  • Arrange a single layer of potatoes in the greased dish.
  • Pour a portion of the cream sauce over the potatoes, then sprinkle some cheese.
  • Repeat this process until all ingredients are used, finishing with a cheese layer.
  • 5️⃣ Bake the Casserole
  • Cover with foil and bake for 40 minutes.
  • Remove foil, sprinkle Parmesan cheese on top, and bake uncovered for 20 minutes until golden brown.
  • 6️⃣ Cool & Serve
  • Let the casserole rest for 10 minutes before slicing.
  • Garnish with fresh herbs and serve warm!

Notes

For extra crispiness: Broil the casserole for the last 3-5 minutes.
For a lighter version: Use low-fat milk and Greek yogurt instead of heavy cream and sour cream.
For meal prep: Assemble ahead and refrigerate for up to 24 hours before baking.
For freezing: Wrap tightly in plastic wrap and aluminum foil; freeze for up to 3 months.
