Easy Sausage and Egg Casserole is a hearty, comforting dish that blends savory sausage, fluffy eggs, and melted cheese into a warm, satisfying meal. It’s perfect for busy mornings or a casual brunch with family and friends. The combination of sausage and eggs is classic, and this casserole turns it into a simple, all-in-one dish that’s ready to go from the oven to the table.
I love making this casserole because it’s so straightforward and comes together quickly. You can even prep it the night before and pop it in the oven in the morning. This saves me so much time when I want a filling breakfast without spending hours in the kitchen. Plus, it’s easy to customize with extra veggies or your favorite cheese to match what you have on hand.
One of my favorite ways to serve this casserole is with a side of fresh fruit and a warm cup of coffee. It makes for a cozy, balanced breakfast or brunch that everyone enjoys. The warm sausage and egg filling feels like a little hug on a plate, perfect for starting the day off right or feeding a crowd.
Key Ingredients & Substitutions
Breakfast Sausage: This gives the casserole its rich, savory flavor. If you want a lighter option, try turkey sausage or plant-based sausage crumbles. Just make sure they’re well seasoned to keep the flavor punch.
Eggs: Eggs are the binder and provide fluffiness. If you’re avoiding eggs, you can try a blend of tofu and chickpea flour, but texture will differ.
Bread Cubes: Day-old bread works best because it soaks up the egg mixture without becoming soggy. Brioche or French bread add sweetness, while whole wheat or sourdough give more nuttiness.
Milk: Whole milk creates a creamy custard. You can swap for any milk you prefer—dairy-free milks like almond or oat will work too, though the texture may be slightly lighter.
Cheese: Cheddar adds a nice sharpness and melts well. Feel free to mix it up with mozzarella, Monterey Jack, or pepper jack for a little spice. Skip or reduce cheese if dairy-free.
How Can I Get the Perfect Casserole Texture Without It Becoming Too Soggy?
Getting the right texture is all about soaking the bread just enough and baking time. Here’s what I do:
- Use day-old or slightly stale bread cubes so they soak up moisture well without falling apart.
- Whisk eggs and milk well before combining with bread to ensure even soaking.
- Let the bread soak for a few minutes before transferring to the dish to absorb the egg mixture.
- Don’t cover the casserole while baking—this keeps the top from getting soggy and helps it brown nicely.
- Bake until just set and slightly golden on top, about 40-45 minutes. Use a knife test in the center to check that the eggs are fully cooked.
Following these steps results in a casserole that’s moist and fluffy inside with a slightly crisp top. It’s a great balance that makes every bite satisfying!
Equipment You’ll Need
- 9×13-inch baking dish – perfect size for even cooking and easy serving.
- Large skillet – to brown and cook the sausage without crowding the pan.
- Mixing bowl – big enough to whisk eggs, milk, and mix all ingredients comfortably.
- Whisk – helps blend eggs and milk smoothly for an even custard.
- Measuring cups and spoons – for precise ingredient amounts and seasoning.
- Spatula or wooden spoon – to stir sausage and fold ingredients together gently.
Flavor Variations & Add-Ins
- Swap sausage for cooked bacon or diced ham—adds a smoky, salty twist.
- Add diced bell peppers and onions for a fresh crunch and sweetness.
- Use pepper jack or mozzarella cheese instead of cheddar for a milder or creamier flavor.
- Stir in chopped spinach or kale to boost nutrition and add color.
Easy Sausage and Egg Casserole
Ingredients You’ll Need:
Main Ingredients:
- 1 pound breakfast sausage (bulk or removed from casings)
- 6 large eggs
- 2 cups whole milk
- 6 cups bread cubes (day-old white bread or brioche works well)
- 2 cups shredded cheddar cheese (optional)
Seasonings & Extras:
- 1 teaspoon salt
- ½ teaspoon black pepper
- ½ teaspoon dried thyme or Italian seasoning (optional)
- ½ teaspoon crushed red pepper flakes (optional for a little heat)
- Butter or cooking spray (for greasing the baking dish)
How Much Time Will You Need?
This recipe takes about 15 minutes to prepare and about 40 to 45 minutes to bake. You can also make it the night before and refrigerate it, then bake fresh in the morning for convenience. Total time, including baking, is about 1 hour.
Step-by-Step Instructions:
1. Prep Your Oven and Dish:
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with butter or cooking spray, so your casserole doesn’t stick.
2. Cook the Sausage:
In a medium skillet over medium heat, cook the sausage until browned and fully cooked. Break it into small crumbles while cooking. Once done, drain any excess grease and set the sausage aside.
3. Mix Eggs and Seasonings:
In a large mixing bowl, whisk together eggs, whole milk, salt, black pepper, dried thyme (if using), and red pepper flakes (if using) until smooth and combined.
4. Combine All Ingredients:
Add the bread cubes, cooked sausage, and shredded cheese (if using) to the egg mixture. Stir gently until the bread is coated fully with the egg mixture.
5. Bake the Casserole:
Pour the mixture into your prepared baking dish. Press down lightly so the bread soaks up the egg mixture. Bake uncovered for 40 to 45 minutes or until the eggs are set and the casserole is golden brown on top. To test, insert a knife in the center — it should come out clean.
6. Cool and Serve:
Once baked, let the casserole cool for about 5 minutes. Serve warm by itself or alongside fresh fruit or a crisp side salad.
This easy sausage and egg casserole is perfect for busy mornings or brunch gatherings. Feel free to add your favorite veggies or swap cheeses to make it your own!

How Should I Store Leftovers?
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or oven until warmed through. This casserole also freezes well — thaw overnight in the fridge before reheating.
