Editor's Note

I love those store-bought croissant packs from Costco, and this recipe is my new favorite way to use them before they go stale. With ham, Gruyère, and buttery croissants, it’s like mini ham and cheese croissant sandwiches wrapped in a creamy custard. It's a total brunch game upgrade!
