Peel 4-5 baking potatoes.

Slice the potatoes into 1/8-inch thick rounds.

Soak the potato slices in ice water for at least 30 minutes.

Drain the potato slices and pat them dry with paper towels.

Melt 1/4 cup of butter.

Crush 2 garlic cloves and combine with the melted butter.

Thinly slice 2 onions.

Grease a deep 10-inch pie plate or casserole dish.

Arrange 1/3 of the potato slices in a slightly overlapping fashion in the dish, starting from the outside edges and continuing to the center.

Layer 1/3 of the onion slices, broken into rings, on top of the potatoes.

Drizzle 1/3 of the butter mixture over the onions.

Season with salt, pepper, and paprika.

Sprinkle 1/3 of the grated parmesan cheese on top.

Repeat the layering process two more times, ending with cheese on top.

Cover the dish and bake at 400 degrees Fahrenheit for 1 hour.

If the cheese is not brown on top, place the dish under the broiler for 4-5 minutes until browned.

Cut into wedges to serve.
