Instructions

Prepare Baking Dish and Croutons: Lightly grease a 9 x 13 inch baking dish. Spread the seasoned croutons in a single layer on the bottom of the dish and set aside.
Cook Sausage: In a skillet over medium heat, brown the Italian sausage until fully cooked, breaking it up into crumbles as it cooks. Drain the cooked sausage on paper towels to remove excess fat.
Layer Cheese and Sausage: Using a box grater, shred the cheddar, Swiss, and pepper jack cheeses. Evenly scatter the shredded cheeses over the croutons in the baking dish. Then layer the browned sausage evenly on top of the cheese.
Mix Egg Custard: In a large mixing bowl, whisk together the eggs, half-and-half, whole milk, Dijon mustard, minced onion, salt, and pepper until well combined.
Assemble and Refrigerate: Pour the egg mixture evenly over the layered sausage, cheese, and croutons in the baking dish. Cover the dish tightly and refrigerate overnight to allow the flavors to meld and the custard to soak into the bread.
Bake: Preheat the oven to 350°F (175°C). Remove the casserole from the fridge, uncover, and bake for 1 hour until the eggs are set and the top is golden and slightly puffed.
Rest and Garnish: Allow the casserole to sit for 15-20 minutes after baking to set up for easier slicing. Garnish with chopped parsley before serving, if desired.

Notes

For best results, prepare the casserole the night before to let the flavors develop and the custard soak thoroughly.
You can substitute Italian sausage with breakfast sausage if preferred.
Feel free to use your favorite cheese blend or adjust cheese quantities to taste.
Seasoned croutons add extra flavor; plain croutons or cubed stale bread can be used as alternatives.
Make sure to let the casserole rest after baking to make slicing cleaner and to enhance texture.
This dish can be reheated covered in the oven or microwave for leftovers.
