A family style breakfast casserole recipe is the easiest way to feed a full table without standing at the stove flipping eggs. It layers bread, eggs, breakfast sausage, and cheese into one dish that bakes until the top is browned and the center is just set. You get a make-ahead breakfast that covers six to eight people from a single pan.
The structure matters more than the exact add-ins. A base of cubed bread soaks up a seasoned egg custard, which keeps the casserole from turning into a flat frittata. Because everything bakes together, the sausage renders its fat into the bread and the cheese forms a salty crust on top. Making this family style breakfast casserole at home is surprisingly straightforward once you know the key steps.
This version is built for a standard 9×13 inch baking dish and uses pantry-stable ingredients. You can assemble it the night before and bake it in the morning, which is why a family style breakfast casserole recipe works for holidays and busy weekends alike.

Why You’ll Love These Family Style Breakfast Casserole
- One dish feeds six to eight with no separate sides required.
- Bread base absorbs egg custard so every bite stays moist, not rubbery.
- Assemble cold the night before and bake straight from the fridge.
- Uses raw breakfast sausage, so no pre-cooking step is needed.
- Freezes baked in portions for up to two months without texture loss.
Ingredients You’ll Need
- 8 cups cubed day-old white bread (about 1 inch pieces, crusts on)
- 1 pound raw breakfast sausage, casings removed, crumbled
- 2 cups shredded cheddar cheese (sharp, not mild)
- 10 large eggs
- 2 cups whole milk
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/2 teaspoon dry mustard powder
- 1/2 cup chopped green onions (white and green parts)
Ingredient Substitutions
White bread: Replace with an equal volume of cubed day-old sourdough for a tangier, chewier base. Sourdough absorbs liquid slower, so let the assembled dish rest 30 minutes longer before baking if made fresh. Expect a denser bite and a more open crumb from the natural starter acids. The family style breakfast casserole works well for weeknight cooking when time is limited.
Breakfast sausage: Swap for 1 pound of diced ham plus 2 tablespoons melted butter mixed into the custard. Ham is already cooked, so the casserole bakes 5 minutes less and loses the rendered-sausage fat that crisps the bread edges. The flavor shifts from savory-spiced to lightly smoky.
Cheddar cheese: Use an equal weight of shredded Monterey Jack for a milder, stringier melt. Jack browns less than cheddar, so place the dish under the broiler for 2 minutes at the end for color. The custard stays creamy but the top loses its sharp bite.
Whole milk: Substitute 2 cups half-and-half for a richer custard with a softer set. Half-and-half contains more fat, so the center stays wobbly longer; add 2 minutes to bake time. The finished slice will cut clean but feel denser on the tongue. For another easy option, check out our gilt bream.
Step-by-Step Instructions
- Grease a 9×13 inch baking dish with butter. Spread the 8 cups cubed bread evenly across the bottom, then scatter the crumbled raw sausage over the bread in an even layer.
- Sprinkle 2 cups cheddar and 1/2 cup green onions across the sausage. Press lightly so the cheese settles between the bread pieces.
- Whisk 10 eggs, 2 cups milk, 1 teaspoon salt, 1/2 teaspoon pepper, and 1/2 teaspoon mustard powder in a bowl until no streaks remain. Pour slowly over the dish so the liquid reaches the bottom.
- Cover with foil and refrigerate 8 hours or overnight. This lets the bread pull in the custard and the sausage season the base.
- Heat the oven to 180°C / 350°F. Bake covered for 30 minutes, then uncover and bake 25–30 minutes more until the top is golden and crispy and the center barely jiggles when shaken.
- Rest on the counter 10 minutes before slicing so the custard firms to a clean cut. Serve from the dish with a flat spatula.
Pro Tips
Cut bread into uneven 1-inch cubes rather than uniform squares; the mix of sizes creates both crisp tops and soft pockets after baking. A baking guide from Food Network confirms that resting egg bakes prevents weeping on the plate.
Use sharp cheddar, not mild, because the sausage dilutes dairy sharpness during the long bake. Pre-shredded cheese contains starch that slows browning, so shred a block if you want a darker crust.
If your fridge runs cold, pull the dish out 20 minutes before baking so the center does not stay undercooked while the edges dry. Cold glass slows heat transfer at the pan floor.
Broil the last 2 minutes only if the top looks pale after the full bake; watch closely because cheese goes from brown to burnt fast under direct heat.
Common Mistakes to Avoid
Skipping the overnight rest leads to floating bread and a soggy bottom because the custard never fully absorbs. Plan the 8 hours chill as a required step, not an option.
Using fresh soft bread instead of day-old causes the base to collapse into paste. Stale bread holds structure; if yours is fresh, leave cubes out 4 hours uncovered first.
Opening the oven before the uncovered stage releases steam that softens the top. Keep the door shut until the foil comes off at the 30-minute mark.
Serving Suggestions
Cut into six large squares or eight smaller ones depending on your crowd. A side of breakfast shot pairs the salty bake with a light citrus lift.
Add a simple non alcoholic toddy on the side for a warm drink that balances the cheese. Fresh tomato slices cut the richness if you serve the casserole at brunch.
Storage and Reheating
Cool leftovers to room temperature within 2 hours, then refrigerate in an airtight container up to 4 days. Reheat single portions at 180°C / 350°F for 15 minutes until the internal temperature reaches 74°C / 165°F.
Wrap baked portions in foil and freeze for up to 2 months. Thaw overnight in the fridge, then reheat from cold using the same oven time. A fruit cocktail makes a bright follow-up to the savory leftovers.
Recipe Variations
Vegetable Version
Add 1 cup diced bell pepper and 1 cup sliced mushrooms with the sausage layer. These release water, so bake 5 minutes longer uncovered. The result is a lighter slice with a sweet-earthy note against the cheese.
Spicy Swap
Replace breakfast sausage with 1 pound chorizo and add 1/2 teaspoon cayenne to the custard. Chorizo is oilier, so the top crisps faster; check at 20 minutes uncovered. Expect a red-tinted custard with a sharp paprika heat.
Gluten-Free Option
Use 8 cups cubed gluten-free bread and confirm the sausage is certified gluten-free. GF bread softens quicker, so reduce the chill to 6 hours. The slice holds but crumbles more at the edges than wheat versions. A irish cream after pairs the warm spice with the bake.
Make-Ahead Freezer
Assemble raw in a foil tray, wrap tight, and freeze before baking up to 1 month. Bake from frozen at 180°C / 350°F for 60 minutes covered then 20 minutes uncovered. The family style breakfast casserole recipe holds its shape though the bread softens slightly more.

Ingredients
Instructions
-
Grease and layer base
Grease a 9x13 inch baking dish with butter, coating the bottom and sides to prevent sticking. Spread the 8 cups cubed bread evenly across the bottom, then scatter the crumbled raw sausage over the bread in an even layer so it will render into the base as it bakes.
-
Add cheese and onions
Sprinkle 2 cups cheddar and 1/2 cup green onions across the sausage in an even layer. Press lightly with your hands so the cheese settles between the bread pieces and the toppings stay put during baking.
-
Whisk egg custard
Whisk 10 eggs, 2 cups milk, 1 teaspoon salt, 1/2 teaspoon pepper, and 1/2 teaspoon mustard powder in a bowl until no streaks remain. The custard should be fully uniform so the seasoning distributes evenly through the bake.
-
Pour custard over dish
Pour the custard slowly over the dish so the liquid reaches the bottom and soaks the bread rather than pooling on top. Use a spatula to gently press any floating bread down into the liquid before covering.
-
Chill overnight
Cover the dish with foil and refrigerate 8 hours or overnight so the bread pulls in the custard and the sausage seasons the base. This required rest prevents a soggy bottom and floating bread when baked.
-
Heat oven and bake covered
Heat the oven to 180°C / 350°F and bake the covered dish for 30 minutes so the center begins to set without drying the edges. Keep the door shut during this stage to hold steam that keeps the top soft.
-
Uncover and finish baking
Uncover and bake 25–30 minutes more until the top is golden and crispy and the center barely jiggles when shaken, indicating the egg is fully set to a safe 71°C / 160°F. If the top looks pale, broil the last 2 minutes while watching closely so the cheese does not burn.
-
Rest and serve
Rest the casserole on the counter for 10 minutes so the custard firms to a clean cut and does not weep on the plate. Serve from the dish with a flat spatula, cutting into six large or eight smaller squares depending on your crowd.
