Preheat your oven to 375°F.
Lightly grease a 9x13-inch baking dish with non-stick spray.
Brown the sausage in a skillet over medium heat, crumbling as it cooks.
Drain any grease from the sausage and set aside.
Unroll the crescent rolls and press them into the bottom of the dish, sealing any perforations to create a solid layer.
Spread the cooked sausage evenly over the crescent roll dough.
In a medium bowl, whisk together the eggs, milk, salt, and pepper.
Pour the egg mixture evenly over the sausage layer.
Sprinkle shredded cheddar cheese over the top.
Bake for 25-30 minutes, or until the eggs are set and the crescent rolls are golden brown.
Let the casserole cool for 5 minutes before slicing into squares.
