Preheat the oven to 375 degrees Fahrenheit and spray a 9 x 13-inch baking dish with nonstick cooking spray.
Dice 1 (12-count) package Hawaiian rolls into 1-inch cubes and add to the prepared baking dish.
Cook 1 pound breakfast sausage in a large skillet over medium heat, breaking it up as it cooks until no pink remains, about 5-8 minutes.
Spread the cooked sausage over the diced rolls. Spread 2 cups shredded cheddar cheese evenly over the top of the sausage.
Whisk together 8 large eggs, ¾ cup half and half, ⅓ cup real maple syrup, ½ teaspoon salt, and ¼ teaspoon ground black pepper in a medium bowl, then pour over the top of the cheese and sausage.
Cover with foil and Bake for 30 minutes. Remove the foil and bake for an additional 8-10 minutes, or until the eggs are fully cooked and the top is lightly browned. Serve warm.
Notes
In the Refrigerator: Store leftovers in an airtight container in the fridge for 3-5 days.
To Reheat: To reheat, microwave individual servings in 30-second increments until warmed through, or heat the entire casserole in the oven at 350ºF for 15 minutes, or until heated through to 165ºF in the center.
In the Freezer: Yes, this is perfect for freezing. Make and bake your breakfast casserole. Once it has completely cooled down, place it in an airtight container or wrap it in a couple layers of plastic wrap, followed by a layer or two of heavy-duty aluminum foil. Lay flat in your freezer for up to 1 month. Thaw from frozen in the refrigerator overnight. Warm individual servings in the microwave until warmed through.
