An easy egg sausage casserole is one of those recipes every home cook should have in their back pocket. It’s simple, dependable, and endlessly adaptable, making it ideal for busy mornings, weekend brunch, holiday breakfasts, and even breakfast-for-dinner nights.
This version is intentionally streamlined. There are no complicated steps, specialty ingredients, or unnecessary extras. Just eggs, milk, sausage, cheese, and bread baked together into a rich, satisfying casserole that slices cleanly and feeds a crowd with minimal effort.
The beauty of this recipe lies in its balance. The eggs provide structure, the sausage adds savory depth, the cheese delivers richness, and the bread absorbs everything into a soft, custard-like base. It’s filling without being heavy and comforting without feeling outdated.
Whether you’re cooking for family, guests, or meal prep, this casserole delivers consistent results every time.
Why This Recipe Works
This egg sausage casserole works because it relies on proven breakfast fundamentals rather than shortcuts.
The egg-to-milk ratio creates a custard that’s firm but tender. The bread cubes absorb moisture and prevent the casserole from becoming dense or rubbery. Pre-cooked sausage ensures even distribution and full flavor without excess grease. Sharp cheddar adds enough bite to keep the dish from tasting flat.
Most importantly, everything bakes together at the same pace. There’s no need for par-baking or layering tricks. Once assembled, the casserole goes straight into the oven and emerges golden, set, and ready to serve.
This recipe is also forgiving. Slight variations in egg count, bread type, or cheese choice won’t ruin the final result, which makes it ideal for everyday cooking.
Ingredient Breakdown
Eggs and Dairy
Eggs
Eggs are the backbone of the casserole. Using 8–10 eggs allows flexibility depending on how firm or custardy you prefer the texture.
Milk
Milk lightens the eggs and creates a smooth, cohesive bake. Whole milk is recommended, but 2% also works.
Protein
Breakfast sausage
Sausage provides savory flavor and fat, which keeps the casserole moist. Pork sausage is classic, but turkey sausage can be substituted.
Bread and Cheese
Bread cubes
Bread absorbs the egg mixture and creates structure. Slightly dried or toasted bread works best.
Sharp cheddar cheese
Sharp cheddar balances the richness of the eggs and sausage. It melts evenly and adds depth without overpowering the dish.
Seasoning
Salt (optional)
Depending on the saltiness of your sausage and cheese, additional salt may not be necessary.
Step-by-Step Instructions
Step 1: Prepare the Baking Dish
Preheat the oven to 350°F. Lightly grease a 9×13-inch baking dish to prevent sticking and ensure easy slicing after baking.
Step 2: Mix the Eggs and Milk
In a large mixing bowl, whisk together the eggs and milk until fully combined. The mixture should be uniform in color with no visible egg whites remaining.
Step 3: Add the Fillings
Add the cooked and crumbled sausage, shredded cheddar cheese, bread cubes, and salt (if using) to the egg mixture.
Stir gently until everything is evenly distributed. Make sure the bread is fully coated with the egg mixture.
Step 4: Assemble the Casserole
Pour the mixture into the prepared baking dish. Use a spatula to spread it evenly, ensuring the sausage and bread are distributed throughout the dish.
Step 5: Bake
Place the casserole in the preheated oven and bake for 30–45 minutes. The casserole is done when the center is set and the top is lightly golden.
A knife inserted into the center should come out mostly clean.
Step 6: Rest and Serve
Remove the casserole from the oven and allow it to rest for 5–10 minutes before slicing. This helps the structure set and makes serving easier.
