Step-by-step method for a croissant breakfast casserole
Step 1
First, preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with cooking spray or butter. Then, layer the torn croissants evenly in the dish. Next, spread the cooked sausage and shredded cheddar cheese over the croissant pieces.
Step 2
Now, whisk together the eggs, milk, salt, black pepper, garlic powder, and onion powder in a large bowl until fully combined. Pour this mixture evenly over the croissant layers. Also, use a spatula to press down gently so the croissants soak up the custard well.
Step 3
Afterward, cover the dish with foil and refrigerate for at least 6 hours or overnight. This overnight rest allows the flavors to meld and the croissants to absorb the custard thoroughly. Finally, remove the foil and bake the casserole uncovered for 40–45 minutes until golden brown on top and set in the center. Let it cool for 10 minutes before garnishing with fresh parsley and serving warm.
