Preheat the oven
Preheat the oven to 350°F (175°C) and lightly grease a baking dish. -

Cut the croissants into thirds and arrange them evenly in the baking dish. -
Make the egg mixture
In a mixing bowl, whisk together the eggs, heavy cream (or milk), salt, garlic salt, pepper, and fresh rosemary. -
Soak and layer
Dip each croissant piece into the egg mixture, then return it to the baking dish. Tuck slices of deli meat and cheese into the gaps between the croissants. -

Notes
-
Use day-old croissants for better absorption and texture
-
Don’t oversoak—quickly dunk the croissants so they stay flaky
-
Mix meats for more depth of flavor
-
Let it rest before cutting to help it hold together
-
For extra crispness, broil for 1–2 minutes at the end
