Ingredients

1 pound (16 ounces) breakfast sausage, cooked, crumbled, drained and cooled (See Tip 1)
6 extra large eggs
1 ¼ cups (10 ounces) half and half (See Tip 2)
1 teaspoon dry mustard
¼ teaspoon Kosher salt
¼ teaspoon freshly ground black pepper
2 cups (5 ounces) seasoned croutons (See Tip 3)
2 cups (8 ounces) shredded extra sharp Cheddar cheese (See Tip 4)
2 Tablespoons sliced green onion tops for garnish (optional)

Instructions

Whisk together the eggs, half and half, dry mustard, salt and pepper until well combined. Add cooked sausage, croutons and cheese. Stir to combine.
Transfer casserole mixture to a gallon ziploc bag. Remove as much air as possible from ziploc bag and seal. Place in refrigerator for at least 4 hours or over night. (See Tip 5)
The next morning, preheat oven to 375°F.
Transfer casserole mixture to a 9-inch greased springform pan or 10 x 10 greased casserole dish. Bake in preheated oven for 45 to 50 minutes or until eggs are set and top is golden brown.
Remove from oven; allow to sit for 10 minutes before removing the sides of the springform pan. If desired, garnish with sliced green onion tops.
Yield: 6 to 8 servings. (See Tip 6)

Notes

I used Jimmy Dean hot sausage. You could also use mild sausage, cooked bacon or diced ham.
You could use whole milk in place of the half and half.
I used cheese and garlic Texas Toast croutons. You could a different seasoned crouton. You can't really taste the seasoning from the croutons, but the seasoning provides a subtle addition to the casserole.
You could also use sharp or mild cheddar cheese, Monterey Jack cheese or other cheese of your choice.
You can by-pass the ziploc bag and place the mixture in the springform pan or casserole dish that you are going to use and cover with aluminum foil. If you place it in a springform pan ahead of time, put the pan on a plate or baking sheet to catch any liquid that may leak out.
Leftovers, if any can be refrigerated and reheated in the microwave for about 1 minute, or in a 350°F oven for 10 to 15 minutes.
