What you’ll need
Gather these items to create your breakfast casserole masterpiece:
- 8 slices of bread, cubed (day-old bread works great!)
- 6 large eggs
- 2 cups milk (whole or your choice of dairy)
- 1 pound breakfast sausage, cooked and crumbled
- 1 cup shredded cheese (cheddar or your favorite)
- 1/2 teaspoon salt
- 1/2 teaspoon pepper
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
Feel free to swap out the sausage for a plant-based option or add in veggies for an extra nutritional boost!
Directions to follow
- Preheat your oven to 350°F (175°C).
- In a large bowl, whisk together the eggs, milk, salt, pepper, garlic powder, and onion powder until well combined.
- In a greased 9×13 inch baking dish, layer the cubed bread. Add the cooked sausage and half of the shredded cheese on top.
- Pour the egg mixture evenly over the layers of bread and sausage.
- Sprinkle the remaining cheese on top.
- Cover the dish with foil and refrigerate overnight, or let it sit for about 30 minutes to absorb the flavors.
- Bake in the preheated oven, covered, for 30 minutes. After this, uncover and bake for an additional 15-20 minutes, or until the casserole is cooked through and the top is golden brown.
- Allow it to cool slightly before slicing and serving.

Best ways to enjoy it
When it comes to serving this breakfast casserole, the possibilities are endless. Cut it into perfect squares and serve warm. It pairs beautifully with fresh fruit, a simple green salad, or even crispy hash browns. For an added splash of flavor, consider topping each slice with salsa, avocado, or a dollop of sour cream. Enjoy it with a cup of your favorite coffee or a refreshing glass of orange juice for the ultimate brunch experience.
Storage and reheating tips
Got leftovers? No problem! This breakfast casserole stores wonderfully. Keep it in an airtight container in the refrigerator for up to 3-4 days. For longer storage, slice and freeze individual portions wrapped in plastic wrap, then place them in a freezer bag. When you’re ready to enjoy it again, thaw overnight in the fridge and reheat in the oven or microwave until warm. Just remember, it’s essential to reheat the casserole thoroughly to ensure food safety.
Helpful cooking tips
- For an extra layer of flavor, consider toasting the bread cubes lightly before layering them in the dish.
- You can add sautéed vegetables such as bell peppers, spinach, or mushrooms for added nutrition and taste.
- If you’re short on time, use pre-cooked sausage to save on prep.
- Take care not to over-bake; the casserole should be set but still moist.
Creative twists
After you’ve mastered the basic version, explore different flavors! Try using Italian sausage and adding some sun-dried tomatoes and mozzarella for a Mediterranean flair. Want to make it vegetarian? Substitute the sausage for a medley of your favorite vegetables and perhaps some feta cheese. The possibilities are as limitless as your imagination!
