Description
A delicious Overnight Croissant Breakfast Casserole featuring buttery croissants, sausage, and cheese, baked to perfection.
Ingredients
Scale
- 1 tbsp olive oil
- 1 small onion, peeled and chopped
- 1 lb breakfast sausage, mild flavor
- 4 large butter croissants or 8 small croissants
- 1 c shredded cheddar cheese
- 6 large eggs
- 1/2 c heavy whipping cream
- 3 c whole milk, divided
- 1/2 tsp dry mustard powder
- 1/2 tsp salt (plus additional for the gravy to taste)
- 1/2 tsp black pepper (plus additional for the gravy to taste)
- 1/4 tsp paprika
- 1/4 tsp garlic powder
- 2 tbsp butter
- 3 tbsp all-purpose flour
Instructions
- Heat olive oil in a skillet; add chopped onions and sauté until soft and translucent.
- Add the sausage to the skillet and cook until browned, then drain the fat (save some for gravy), and let it cool slightly.
- Tear croissants into pieces and combine them with the sausage mixture and shredded cheese in a bowl.
- Spread the croissant mixture into a greased 9×13-inch baking dish.
- Whisk together eggs, heavy cream, half a cup of milk, and spices in a bowl; pour over the croissant mixture.
- Cover the dish and refrigerate overnight.
- The next day, preheat the oven to 350°F (175°C). Bake the casserole for 35 to 45 minutes until golden brown on top.
- While baking, prepare the gravy by melting butter with reserved sausage fat, stirring in flour, and gradually adding 2½ cups of milk, cooking until thickened. Season with salt and pepper.
- Serve the casserole hot with gravy on the side.
Notes
- For a spicier kick, use spicy sausage instead of mild.
- Can substitute croissants with other types of bread if desired.
- Leftovers can be stored in an airtight container in the refrigerator for up to 3 days.
