When you need a hearty breakfast that can feed a crowd without keeping you in the kitchen all morning, Breakfast Sausage Casserole is hard to beat. This comforting overnight breakfast bake combines savory sage pork sausage, sharp Cheddar cheese, soft bread, and a rich egg custard in one easy casserole.
This recipe is courtesy of Trisha Yearwood and is featured by Food Network as an easy, make-ahead breakfast casserole. It yields 12 servings and has a total listed time of about 9 hours 10 minutes, including the overnight chilling and resting period.
The best part is that most of the work happens the night before. You layer the bread, cooked sausage, and cheese in a casserole dish, pour over the seasoned egg mixture, cover it, and refrigerate it overnight. The next morning, simply bake it until golden and set.
Why You’ll Love This Breakfast Sausage Casserole
This sausage breakfast casserole is designed for convenience without sacrificing flavor. The overnight soak allows the bread to absorb the egg custard, creating a tender, savory interior while the cheese melts throughout the casserole.
The combination of sage pork sausage and sharp Cheddar gives the dish a rich, savory flavor, while dry mustard adds a subtle tang that helps balance the richness. Food Network specifically recommends allowing the assembled casserole to chill for at least eight hours so the bread can absorb the custard and the flavors can meld.
It is especially useful for:
- Christmas morning breakfast
- Thanksgiving brunch
- Weekend family breakfasts
- Holiday gatherings
- Bridal or baby showers
- Weekend brunch parties
- Breakfast-for-dinner meals
- Feeding a large group
Because everything bakes in one dish, serving and cleanup are also relatively simple.
Ingredients You Need
The original Food Network recipe uses a short list of straightforward ingredients:
- Butter, for greasing
- ½ loaf sliced white loaf bread
- 1 pound fresh bulk pork sausage with sage
- 10 ounces sharp Cheddar cheese, grated
- 2 cups half-and-half
- 1 teaspoon dry mustard
- 1 teaspoon salt
- 5 large eggs, lightly beaten
The recipe is designed for a 9-by-13-by-2-inch casserole dish and makes 12 servings.
Why These Ingredients Work
White bread: The bread absorbs the egg mixture and gives the casserole its soft, custardy texture. Food Network recommends using a hearty white loaf rather than an extremely soft sandwich bread because sturdier bread holds its shape better during baking.
Sage pork sausage: Sage adds a classic savory breakfast flavor. Using bulk sausage also makes it easy to brown and break into pieces.
Sharp Cheddar: Sharp Cheddar provides a strong cheesy flavor that stands up to the sausage and eggs.
Half-and-half: This gives the custard richness, moisture, and a creamy texture.
Dry mustard: A small amount adds savory depth and helps balance the richness.
Eggs: Eggs bind the casserole together and create the tender custard surrounding the bread and sausage.
How to Make Breakfast Sausage Casserole
1. Prepare the Bread
Start by greasing a 9-by-13-by-2-inch casserole dish with butter.
Cut the sliced white bread into approximately 1-inch cubes and spread them evenly across the bottom of the dish.
Try to distribute the bread in a relatively even layer so that the egg mixture can soak through the casserole consistently.
2. Brown the Sausage
Place the bulk sage pork sausage in a skillet over medium heat.
Cook it until it is completely browned and no longer pink. Break it into smaller pieces as it cooks.
Once finished, remove the sausage from the skillet with a slotted spoon so excess fat can drain away. Food Network recommends this step because draining the sausage helps prevent the finished casserole from becoming overly greasy.
3. Layer the Sausage and Cheese
Spread the cooked sausage evenly over the bread cubes.
Next, sprinkle the grated sharp Cheddar over the sausage.
Creating distinct layers helps distribute the bread, sausage, and cheese throughout the casserole so each serving gets a balanced combination of ingredients.
4. Make the Egg Custard
In a bowl, combine the half-and-half, dry mustard, salt, and lightly beaten eggs.
Gently mix everything together until combined.
Lightly beating the eggs rather than aggressively whipping them helps create a smooth, uniform custard instead of introducing excessive air into the mixture.
5. Pour Over the Casserole
Slowly pour the egg mixture over the bread, sausage, and cheese.
Make sure the liquid is distributed across the entire casserole rather than concentrated in one area.
Cover the casserole tightly with aluminum foil and refrigerate it for at least 8 hours or overnight.
This overnight resting period is one of the most important parts of the recipe because the bread needs time to absorb the custard.
6. Bake the Casserole
The following morning, preheat your oven to 350°F.
Keep the casserole covered and bake it until the center is set and the top is slightly golden. The original recipe lists approximately 50 minutes of baking time.
Because ovens vary, look for a casserole that is set in the center rather than relying solely on the clock.
Once baked, remove the casserole from the oven and allow it to rest for approximately 15 minutes before serving. This gives the custard time to finish setting and makes the casserole easier to cut and serve.
Tips for the Best Breakfast Sausage Casserole
Use Sturdy Bread
The type of bread can affect the final texture. A hearty white loaf is preferable to very soft sandwich bread because it is better able to absorb the custard while retaining some structure.
Brown and Drain the Sausage
Do not skip browning the sausage. Cooking it first develops deeper savory flavor and allows excess fat to be removed before it goes into the casserole.
Don’t Overbeat the Eggs
The goal is a smooth custard, not a foamy mixture. Lightly beat the eggs before combining them with the other ingredients.
Give It Enough Chilling Time
This is not a recipe to assemble and immediately bake. The overnight soak is what allows the bread to absorb the egg mixture properly.
Avoid Overbaking
For a tender casserole, bake only until the center is set and the top is lightly golden. Overbaking can make the eggs firm and dry.
Let It Rest
Allowing the casserole to sit for 15 minutes after baking helps it settle and makes serving easier.
What to Serve With Breakfast Sausage Casserole
Because this casserole is rich and filling, fresh or lighter sides make excellent companions.
Try serving it with:
- Fresh fruit salad
- Mixed berries
- Greek yogurt
- Yogurt parfaits
- Fresh muffins
- Pastries
- Roasted vegetables
- Simple green salad
Food Network also recommends fruit, yogurt, parfaits, muffins, pastries, green salad, and roasted vegetables as suitable sides.
For a holiday brunch, add fresh fruit, coffee, orange juice, and a simple pastry platter for an easy spread.
Easy Ways to Customize It
The original recipe has a classic combination of bread, sage sausage, eggs, and Cheddar, but breakfast casseroles are naturally flexible.
You can experiment with different cheeses, such as Monterey Jack, Colby, or a mild cheddar, depending on the flavor you want.
For extra vegetables, consider serving the casserole alongside sautéed spinach, mushrooms, bell peppers, or roasted tomatoes.
If you prefer a spicier breakfast, a hot sausage can add more heat. Just remember that changing the sausage can also change the overall seasoning and salt level.
The most important thing is to maintain the basic balance between bread, egg custard, sausage, and cheese so the casserole retains its structure.
How to Store Leftovers
Breakfast sausage casserole is particularly convenient for meal planning because leftovers can be stored and reheated.
According to Food Network, cooled leftovers can be transferred to an airtight container and refrigerated for up to 5 days. They can be reheated in either the microwave or oven until warmed through.
For longer storage, cooled portions can be frozen for up to 3 months. For best results, thaw frozen casserole overnight in the refrigerator before reheating.
Freezing individual portions is especially convenient if you want quick breakfasts throughout the week.
Why It’s Perfect for Holiday Breakfast
Christmas morning and other holidays can be hectic, especially when you are preparing food for several people.
This is where an overnight breakfast casserole shines. Instead of waking up early to cook sausage, eggs, bread, and cheese separately, you can assemble the casserole the evening before.
The next morning, place it in the oven while you prepare coffee, fruit, pastries, or other brunch dishes.
Food Network describes this style of breakfast casserole as particularly suitable for holidays and weekend brunch because it can be prepared ahead and easily serves a crowd.
Final Thoughts
Breakfast Sausage Casserole is a comforting, make-ahead breakfast that combines everything you want in a hearty morning meal: savory sage sausage, sharp Cheddar, tender bread, and creamy baked eggs.

Whether you’re planning Christmas morning, a weekend brunch, or simply want an easy breakfast for a busy family, this classic sausage casserole is a reliable choice. The simple ingredients, overnight preparation, and crowd-friendly portions make it a recipe worth saving.
