Ingredients
6 large eggs
2 cups milk
6 cups cubed bread (French, Italian, sourdough, or brioche work well)
1 pound breakfast sausage, cooked and crumbled
2 cups shredded cheese such as cheddar or Monterey Jack
1 teaspoon dry mustard powder
1/2 teaspoon salt
1/4 teaspoon black pepper
Optional: 1 cup diced vegetables such as bell peppers or onions
Step-by-Step Instructions
Step 1: Prepare the baking dish
Grease a 9×13 inch baking dish with butter or non-stick spray, making sure all corners are coated.
Step 2: Add the bread
Spread the cubed bread evenly across the bottom of the baking dish.
Step 3: Add the sausage and vegetables
Sprinkle the cooked, crumbled sausage over the bread. If you are using vegetables, distribute them evenly at this stage.
Step 4: Add the cheese
Scatter the shredded cheese evenly over the sausage and bread.
Step 5: Mix the egg base
In a large mixing bowl, whisk together the eggs, milk, dry mustard, salt, and pepper until smooth and fully combined.
Step 6: Pour the mixture
Slowly pour the egg mixture over the bread mixture in the baking dish, making sure all bread pieces get moistened.
Step 7: Refrigerate
Cover the dish tightly with plastic wrap and refrigerate for at least 4 hours or overnight.
Step 8: Bake the casserole
When ready to bake, preheat the oven to 350°F (175°C). Remove the plastic wrap and bake, uncovered, for 45–55 minutes, or until the top is golden and the center is set.
Step 9: Rest and serve
Remove from the oven and let the casserole rest for 5–10 minutes before slicing and serving.
Variations

Add cooked mushrooms, spinach, or tomatoes for extra veggies
Use Swiss, Gouda, or pepper jack cheese for a different flavor
Swap the sausage for a plant-based alternative to make it meatless
Use brioche or croissants for a richer, softer texture

FAQs
Can I use a different type of bread?
Yes. Sourdough, brioche, whole wheat, or any sturdy bread works well. Day-old bread absorbs the egg mixture best.
Can I make this without meat?
Absolutely. Omit the sausage or replace it with a plant-based option or extra vegetables.
How do I know when the casserole is fully baked?
The edges will be golden, the top puffed, and a knife inserted in the center should come out clean.
Can I freeze it?
Yes. A fully baked casserole can be cooled, wrapped tightly, and frozen for up to 2 months.
