How to Make Easy Sausage Croissant Breakfast Casserole

  1. Cook the Sausage: Heat a skillet over medium-high heat and brown the sausage, breaking it into small crumbles for about 8-10 minutes until deeply browned. Drain any excess fat.

  2. Prepare the Croissants: Tear the croissants into 2-inch chunks and spread them evenly in a 9×13 inch baking dish, ensuring every piece has a chance to soak up that custard.

  3. Layer the Ingredients: Distribute the browned sausage evenly over the croissant chunks, then sprinkle the shredded cheddar cheese generously over the top for that melty goodness.

  4. Mix the Custard: In a large bowl, whisk together the eggs, half-and-half, mustard, onion powder, salt, black pepper, and nutmeg until the mixture is smooth and well combined.

  5. Combine and Press: Pour the custard mixture over the sausage and cheese layer, and gently press down on the croissants to ensure they absorb the delicious flavors.

  6. Refrigerate Overnight: Cover the baking dish tightly and refrigerate for at least 8 hours, but preferably overnight, allowing the croissants to soak up all the flavors.

  7. Bring to Room Temp: Remove the casserole from the refrigerator and let it sit at room temperature for about 15 minutes while you preheat the oven to 325°F.

  8. Bake the Casserole: Bake covered with foil for 35 minutes, then remove the foil and bake uncovered for an additional 25 minutes until the top is golden brown and fragrant.

  9. Rest and Serve: Once baked, remove from the oven and let it rest for 10 minutes before cutting into squares to serve warm, enjoying the aroma wafting through your kitchen.
