Preheat your oven to 375°F and generously grease a 9x13-inch baking dish (or similar size that will accommodate all 16 crescent rolls in a single layer). This ensures even heat distribution and prevents sticking. While the oven preheats, take your eggs out if they're cold—room temperature eggs will incorporate more evenly into the custard mixture.

Unroll the crescent roll dough and separate it into individual rolls. Arrange all 16 rolls in your prepared baking dish, pressing them gently together to form an even base layer. The rolls will expand during baking, so don't worry if there are small gaps between them—they'll fill in nicely. This creates the structural foundation for your breakfast bake.

In a large mixing bowl, whisk together the room temperature eggs, whole milk, salt, and freshly ground black pepper until well combined and slightly frothy. I like to use freshly ground pepper rather than pre-ground because it has so much more flavor and really brightens up the egg custard. This mixture will soak into the crescent rolls and create a custardy, savory center.

Stir the diced ham and half of the shredded cheddar cheese into the egg custard mixture from Step 3, along with half of the chopped green onions. Pour this entire mixture evenly over the crescent rolls in your baking dish. Then sprinkle the remaining cheddar cheese over the top as an even layer—this will create a golden, melted cheese crust on top. I find that Cabot cheddar melts beautifully and creates excellent color, but any good-quality cheese will work.

Place the assembled bake in your preheated 375°F oven and bake for 25-30 minutes, until the crescent rolls are golden brown on top and the egg custard is set (the center should jiggle slightly when gently shaken but not slosh around). The exact time depends on your oven, so start checking around 25 minutes. The cheese on top should be melted and bubbling slightly at the edges.

Remove the bake from the oven and let it rest for 2-3 minutes—this allows the custard to set up a bit more for cleaner serving. Sprinkle the reserved green onions over the top for a fresh garnish and a pop of color. Serve warm directly from the baking dish, cutting into squares for individual portions.
