Ingredients
  

  • 1 pound breakfast sausage (ground bulk susage)
  • 15 oz croissants (about 6 large)
  • 6 oz sharp cheddar cheese (shredded)
  • 8 large eggs
  • ½ cup 2% milk
  • ¼ teaspoon black pepper (ground)

Instructions
 

  • Grease a 9"x13" pan or 3-quart casserole dish.
  • Slice the croissants horizontally using a serrated bread knife and place them in the casserole dish with the cut sides facing up.
  • Cook the sausage in a skillet over medium-high heat until browned, breaking it down into small crumbles.
  • Drain the sausage well and distribute it evenly among the croissants. Sprinkle the cheese evenly over the sausage.
  • Whisk together the eggs, milk, and pepper in a medium bowl. Pour the custard mixture over the croissants, dividing it evenly over each one.
  • Cover the casserole with plastic wrap and refrigerate for at least 2 hours and up to overnight.
  • The next morning, take out the casserole to bring it to room temperature. Preheat the oven to 375°F.
  • Remove the plastic wrap and replace with a sheet of foil. Bake the casserole for 20 minutes. Remove the foil and bake an additional 15 minutes, uncovered, or until browned and crisp. The internal temperature should reach 160°F.
  • Remove from the oven and allow the casserole to rest for 5 minutes before serving.
