Cheddar is more accessible and provides a similar flavor profile.

Wash the potatoes thoroughly.

Peel the potatoes and boil them for 5 minutes to soften slightly.

Preheat the oven to 350°F (175°C).

Slice the potatoes into thin slices.

Fill a large pot with water, add half a teaspoon of salt, and bring it to a boil.

Once boiling, add the sliced potatoes and cook for 3 to 5 minutes until slightly tender.

Drain the potatoes and set aside.

In a large pot, melt 3 to 4 tablespoons of butter over medium heat.

Add the diced onion and sauté for about 1-2 minutes.

Sprinkle in the flour gradually while whisking to avoid lumps, cooking for 1-2 minutes.

Slowly add 1 1/2 cups of milk while whisking continuously to ensure a smooth sauce.

Add 1 cup of shredded cheddar cheese to the sauce and mix until melted and smooth.

Season the sauce with 1 teaspoon of salt, black pepper, and optional cayenne pepper, adjusting to taste.

Spray a casserole dish with cooking spray to prevent sticking.

Spread a layer of the cheese sauce on the bottom of the casserole dish.

Layer the boiled potatoes evenly over the sauce.

Repeat the layering process with more sauce and potatoes until all are used, finishing with a layer of sauce on top.

Top with 1/3 cup of extra cheese and a sprinkle of Parmesan cheese.

Bake in the oven at 300°F (150°C) for 45 minutes or until the top is golden brown.

Garnish with parsley before serving.
