Preheat your oven to 375°F (190°C).

In a large skillet over medium heat, brown the ground beef for about 5–7 minutes, then drain excess fat.

In a mixing bowl, combine heavy cream and seasonings, whisk until smooth to prepare the creamy sauce.

Layer half of the scalloped potatoes in a greased baking dish, followed by half of the browned beef and creamy sauce. Repeat layers.

Cover with aluminum foil and bake for 1 hour, then uncover and bake for an additional 15 minutes until golden.

Let the casserole rest for 10 minutes before serving. Cut into squares and enjoy.
