Ingredients

½ pound ground breakfast sausage
6 large eggs
1 cup milk
2 slices white bread
1 cup cheddar cheese shredded
1 teaspoon yellow mustard
¾ teaspoon salt
chopped chives for garnish

Instructions

The night before serving, add sausage to a medium skillet over medium-high heat and cook until browned. Use a wooden spoon or spatula to stir and break up into smaller pieces. Continue cooking until browned. Set aside.
In a large mixing bowl, combine eggs, milk, mustard, and salt. Whisk thoroughly.
Add cubed bread and cooked sausage to egg mixture. Stir until combined.
Spray an 8" square baking dish with cooking spray and pour egg mixture in.
Sprinkle the top with shredded cheddar cheese.
Cover the casserole dish with plastic wrap and refrigerate overnight.
The next morning, preheat oven to 325°F (176°C).
Remove cover from casserole and bake for 35-45 minutes until the top is lightly browned and a meat thermometer inserted in the center registers 160°F (71°C). Remove from oven and let cool for 5 minutes. Serve warm.

Notes

To save time and make preparation even easier, you can chop up pre-cooked sausage links or patties or add prepared sausage crumbles. For a healthier version, use turkey or chicken sausage instead.
