Ingredients

• 1 pound Ground breakfast sausage
• 6 slices White bread
• 2 cups Shredded sharp cheddar cheese
• 6 count Large eggs
• 2 cups Whole milk
• 1 teaspoon Salt
• 0.5 teaspoon Black pepper
• 0.5 teaspoon Ground mustard
• 1 tablespoon Butter
• 1 tablespoon Chopped fresh parsley (optional for garnish)

Directions

Step 1

Preheat your oven to 350°F (175°C). Grease a 9x13-inch baking dish with the butter.

Step 2

In a large skillet over medium heat, cook the ground breakfast sausage until browned and fully cooked, breaking it up into small pieces with a spatula. Drain any excess grease and set aside.

Step 3

Cut the white bread slices into 1-inch cubes. Spread the bread cubes evenly in the greased baking dish.

Step 4

Sprinkle the cooked sausage evenly over the bread cubes. Then, sprinkle the shredded sharp cheddar cheese over the top.

Step 5

In a large mixing bowl, whisk together the eggs, milk, salt, black pepper, and ground mustard until well combined.

Step 6

Pour the egg mixture evenly over the bread, sausage, and cheese in the baking dish, ensuring that all the bread cubes are soaked.

Step 7

Cover the baking dish with aluminum foil and bake in the preheated oven for 30 minutes.

Step 8

After 30 minutes, remove the foil and bake for an additional 15 minutes, or until the casserole is golden brown on top and the eggs are set in the middle.

Step 9

Remove the casserole from the oven and allow it to rest for 5-10 minutes before slicing and serving.

Step 10

Optional: Garnish with chopped fresh parsley before serving.
