Can you make croissant casserole ahead of time?

Yes, you can absolutely make a croissant breakfast casserole ahead of time! Assemble the casserole, cover it tightly, and refrigerate it for up to 24 hours. Add the topping just before baking for best results. This is perfect for a stress-free holiday brunch.

What do you eat with breakfast casserole?

Croissant breakfast casserole pairs well with a variety of sides. Consider serving it with fresh fruit salad, yogurt parfaits, a simple green salad with a light vinaigrette, or even some crispy bacon or sausage on the side. Orange juice, mimosas, or coffee are great drink options.

How do you keep croissant casserole from getting soggy?

To prevent sogginess, ensure the croissants are slightly stale or day-old. You can also lightly toast them before adding them to the casserole. Be careful not to over-saturate the croissants with the egg mixture. Letting the casserole rest for 15-20 minutes before baking helps the croissants absorb the liquid evenly and prevent a soggy bottom.

What is the best cheese to use in breakfast casserole?

The best cheese for a breakfast casserole depends on your preference! Cheddar cheese (sharp or mild), Gruyere, Monterey Jack, and Swiss cheese are all excellent choices. You can also use a blend of cheeses for a more complex flavor profile.

How long does breakfast casserole last in the fridge?

Cooked breakfast casserole will typically last for 3-4 days in the refrigerator when stored properly in an airtight container. Ensure it has cooled completely before refrigerating.

What can I add to breakfast casserole to make it more exciting?

To elevate your croissant breakfast casserole, consider adding sun-dried tomatoes, sautéed mushrooms, caramelized onions, bell peppers, spinach, or even a sprinkle of red pepper flakes for a touch of heat. Different types of sausage or ham can also add unique flavors.

Instructions

Prep the base by tearing croissants into pieces and placing them in a greased 9×13 inch baking dish.
Cook sausage in a skillet until browned. Transfer to a plate, leaving drippings. Saute onion and bell pepper in the same skillet until soft.
Layer the casserole by scattering cooked sausage, sauteed veggies, and frozen hash browns over the croissant pieces. Sprinkle 1.5 cups of cheese on top.
Make the custard by whisking eggs, milk, cream, dry mustard, salt, pepper, and garlic powder in a large bowl until smooth.
Assemble and rest by slowly pouring the custard evenly over the casserole. Press down gently to soak the croissants. Top with remaining 1/2 cup cheese. Let rest 20-30 minutes or cover and refrigerate overnight.
Preheat oven to 350°F (175°C). Bake uncovered for 50-60 minutes, until the center is set and top is golden brown. Let cool for 10 minutes before slicing and serving.

Notes

Day-old croissants work best. Letting the assembled casserole rest before baking is crucial for even texture. For a lighter version, use 2% milk and reduce the cheese. Can be made vegetarian with plant-based sausage or mushrooms.
