Recipe Information
Ingredients
- 8 large eggs
- 2 cups milk
- 1 teaspoon salt
- 0.5 teaspoon black pepper
- 0.5 teaspoon Italian seasoning
- 6 cups day-old bread, cubed
- 2 cups shredded cheddar cheese
- 1 cup cooked breakfast sausage, crumbled (optional)
- 1 cup diced bell peppers
- 0.5 cup diced onion
- 1 cup chopped spinach (optional)
Instructions
Grease a 9x13-inch casserole dish with cooking spray or butter.
In a large mixing bowl, whisk together the eggs, milk, salt, black pepper, and Italian seasoning until well combined.
Add the cubed bread to the egg mixture, stirring to ensure all the bread is evenly coated.
Fold in the shredded cheddar cheese, cooked breakfast sausage (if using), bell peppers, onion, and spinach.
Pour the mixture into the prepared casserole dish, spreading it out evenly.
Cover the dish tightly with aluminum foil or plastic wrap and refrigerate for at least 8 hours or overnight to allow the flavors to meld.
When ready to bake, preheat your oven to 350°F (175°C).
Remove the casserole from the refrigerator and let it sit at room temperature for 15-20 minutes while the oven preheats.
Bake the casserole, uncovered, for 40-45 minutes, or until the top is golden brown and the center is set. A knife or toothpick inserted into the middle should come out clean.
Remove from the oven and allow the casserole to cool for 5-10 minutes before slicing and serving. Enjoy!
