In a large pot, heat the oil or butter over medium heat.
Add the ground meat and cook until browned, breaking it up as it cooks.
Stir in the sliced leeks and cook for about 5–7 minutes until softened.
Pour in the broth and bring to a gentle simmer.
Add the cream and cheese. Stir continuously until the cheese melts into a creamy consistency.
Season with salt, pepper, and optionally nutmeg to taste.
Simmer for another 10 minutes to allow flavors to meld.
Serve hot with crusty bread or toast.
