Step-by-step overview

Preparing this delightful Family-Style Breakfast Casserole Bake begins the night before, or at least a few hours in advance, by layering bread, cooked sausage, eggs, and cheese into a baking dish. You’ll pour a rich, seasoned egg mixture over everything, allowing it to soak in overnight, which is key to its moist and flavorful texture. The next day, it’s a simple matter of baking it until it’s golden brown and puffed up, yielding a glorious dish that smells as good as it tastes.

Key ingredients

To bring this amazing brunch to life, you’ll need a handful of accessible and delicious ingredients:

Bread: 8 slices of sourdough or brioche, cubed (approximately 6-7 cups)
Breakfast Sausage: 1 pound, cooked and crumbled
Eggs: 12 large
Milk: 2 cups (whole or 2% works best for richness)
Heavy Cream: 1/2 cup (optional, for extra richness)
Cheddar Cheese: 2 cups, shredded
Monterey Jack or Colby Jack Cheese: 1 cup, shredded (for extra meltiness)
Dijon Mustard: 1 tablespoon
Onion Powder: 1 teaspoon
Garlic Powder: 1 teaspoon
Salt: 1 teaspoon
Black Pepper: 1/2 teaspoon
Fresh Chives or Parsley: For garnish (optional)
Smoked Paprika: 1/2 teaspoon (optional, for a deeper flavor)

Ingredient Note: While sourdough provides a lovely tang and structure, brioche will give you a sweeter, richer casserole that’s almost dessert-like. Don’t be afraid to mix and match your cheeses for a more complex flavor profile!

Directions to follow

Here’s how to assemble this incredible breakfast casserole:

Prep the Bread: Lightly grease a 9×13-inch baking dish. Arrange half of the cubed bread evenly over the bottom of the dish.
Layer the Sausage: Sprinkle the cooked and crumbled breakfast sausage over the bread.
Add Cheese: Distribute 1 1/2 cups of the shredded cheddar cheese and all of the Monterey Jack evenly over the sausage layer.
Top with More Bread: Place the remaining cubed bread over the cheese layer.
Whisk the Egg Mixture: In a large bowl, whisk together the eggs, milk, heavy cream (if using), Dijon mustard, onion powder, garlic powder, salt, black pepper, and smoked paprika (if using) until well combined and slightly frothy.
Pour and Soak: Carefully pour the egg mixture evenly over the bread and sausage layers in the baking dish, making sure all the bread is moistened.
Chill: Cover the dish tightly with plastic wrap and refrigerate for at least 4 hours, or preferably overnight, to allow the bread to fully absorb the egg mixture.
Preheat and Bake: When ready to bake, preheat your oven to 375°F (190°C). Remove the casserole from the refrigerator and let it sit at room temperature for about 20-30 minutes while the oven preheats.
Finish with Cheese: Uncover the casserole and sprinkle the remaining 1/2 cup of shredded cheddar cheese over the top.
Bake to Perfection: Bake for 45-55 minutes, or until the casserole is puffed, golden brown, and a knife inserted into the center comes out clean.
Rest and Serve: Let the casserole rest for 5-10 minutes before slicing and serving. Garnish with fresh chives or parsley, if desired.

Best ways to enjoy it

This casserole is a complete meal on its own, but you can certainly elevate the experience with a few thoughtful additions. A simple green salad with a light vinaigrette offers a refreshing contrast to the richness of the casserole. For something sweet, a fruit salad featuring berries, melon, and grapes would be a perfect complement. You could also serve it with a side of crispy bacon or roasted potatoes for an even heartier spread. And, of course, no brunch is complete without good coffee or fresh orange juice!

Keeping leftovers fresh

Any leftover Family-Style Breakfast Casserole Bake can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat individual portions, simply place them in the microwave for 1-2 minutes, or until warmed through. For a crisper reheat, pop a slice into a toaster oven or conventional oven at 300°F (150°C) for about 10-15 minutes. This casserole also freezes beautifully. Once completely cooled, cut it into individual portions and wrap each tightly in plastic wrap, then aluminum foil. Freeze for up to 2-3 months. Thaw overnight in the refrigerator before reheating.

Helpful cooking tips

Don’t Skimp on Soaking Time: The overnight soak is crucial. It allows the bread to fully absorb the egg mixture, preventing a dry casserole and ensuring a moist, flavorful result.
Cook Sausage Ahead: Cooking the sausage a day or two before you assemble the casserole can save you even more time on prep day. Make sure to drain off any excess grease.
Use Stale Bread: Slightly stale bread works wonders as it absorbs the custard more effectively without becoming mushy. If your bread is fresh, you can gently toast the cubes in the oven for 10-15 minutes at 250°F (120°C) to dry them out a bit.
Avoid Overbaking: Keep an eye on the casserole. You want it puffed and golden, but not overly browned or dry. A knife inserted near the center should come out clean, indicating the eggs are set.

Creative twists

Veggie Loaded: Add sautéed bell peppers, spinach, mushrooms, or diced tomatoes to the sausage layer for extra flavor and nutrients.
Spicy Kick: Include a pinch of cayenne pepper in the egg mixture or sprinkle some red pepper flakes over the top before baking. A dash of hot sauce on the side is also fantastic.
Different Meats: Swap the breakfast sausage for crumbled cooked bacon, diced ham, or even a vegetarian sausage alternative.
Cheese Please: Experiment with different cheese combinations. Swiss, Gruyère, provolone, or even a little cream cheese can add unique dimensions.
Herbaceous: Mix in fresh herbs like thyme, rosemary, or sage with the egg mixture for an aromatic boost.

Common questions

Can I make this casserole gluten-free?

Absolutely! Simply substitute the regular bread with your favorite gluten-free bread. Ensure it’s a sturdy loaf that can hold up to the overnight soak.

What if I don’t have heavy cream?

While heavy cream adds a lovely richness, you can omit it. The casserole will still be delicious. You might notice a slight difference in texture, but it won’t compromise the dish.

Can I prepare this without the overnight soak?

You technically can, but the results won’t be as good. If you’re really short on time, let it soak for at least 2-3 hours in the refrigerator. The longer it soaks, the better the bread absorbs the egg mixture, leading to a more consistent and flavorful texture.

My casserole looks brown on top but is still wobbly in the middle. What should I do?

This often means the internal temperature hasn’t reached the desired level. Cover the casserole loosely with aluminum foil to prevent the top from burning, and continue baking for an additional 10-15 minutes, or until a knife inserted into the center comes out clean.
