Easy Sausage and Egg Casserole is a simple, comforting dish that’s perfect for breakfast or brunch. It combines hearty sausage, fluffy eggs, and melted cheese into one warm, satisfying bake. The flavors are familiar and cozy, making it a great choice for a family meal or a weekend treat.
I love making this casserole because it comes together quickly and can be prepared ahead of time. Sometimes, I mix in a little extra cheese or sprinkle some fresh herbs on top just before baking to add a bit of extra flavor. It’s one of those dishes that feels like a big, warm hug on a plate, and everyone always asks for seconds.
My favorite way to serve it is with a side of fresh fruit and some crusty toast. It’s great for feeding a crowd or just enjoying a relaxed morning at home. If you’re ever in a pinch and need something filling and tasty, this casserole is a go-to for me every time.
Key Ingredients & Substitutions
Breakfast Sausage: This brings a lot of flavor and richness to the dish. You can swap with turkey sausage or plant-based sausage if you want a leaner or vegetarian option. Just cook it fully before adding.
Eggs: Eggs are the base, giving the casserole structure and fluffiness. Use large eggs for the best texture. For a dairy-free version, try adding extra veggies and tofu instead.
Milk: Whole milk adds creaminess, but half-and-half or heavy cream makes it even richer. For lighter or lactose-free needs, use almond milk or oat milk, though it might change the texture a bit.
Cheddar Cheese: Cheddar melts nicely and adds sharp flavor. Feel free to mix in mozzarella or Monterey Jack for milder taste or use vegan cheese alternatives.
How Do You Get a Perfectly Set, Golden Brown Casserole?
Setting the casserole just right is key—firm but still moist—and the top should have a nice golden finish. Here are a few tips:
- Use a gentle whisk when mixing eggs and milk to avoid too many bubbles that cause cracks.
- Don’t cover the dish while baking; you want the cheese to brown and get a bit crispy.
- Start baking at 350°F (175°C) – this moderate heat cooks evenly without drying out the eggs.
- Check at 30 minutes by gently shaking. If it jiggles like jelly, bake a little longer.
- Let the casserole rest for 5 minutes after baking to fully set before slicing.
These simple steps will help you get a fluffy, tender casserole with a golden top every time.
Equipment You’ll Need
- 9×13-inch baking dish – perfect size for even cooking and easy serving.
- Large skillet – you’ll brown the sausage here; a nonstick one makes cleanup simple.
- Mixing bowl – for whisking eggs and mixing all ingredients smoothly.
- Whisk – helps blend eggs and milk without lumps for a creamy texture.
- Spatula or wooden spoon – great for stirring cooked sausage and folding in cheese.
Flavor Variations & Add-Ins
- Swap sausage for cooked bacon or ham for a different meaty flavor.
- Add chopped bell peppers or spinach for a fresh, colorful veggie boost.
- Try pepper jack cheese to add a little spicy kick.
- Mix in chopped green onions or fresh herbs like chives for extra brightness.

- 2 cups shredded cheddar cheese

How Much Time Will You Need?
Prepare for about 10 minutes of prep time and around 30 to 40 minutes for baking. Plan a few extra minutes for cooling before serving. It’s a quick and easy dish that fills your kitchen with delicious aromas as it bakes.
Step-by-Step Instructions:
1. Cook the Sausage:
Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with cooking spray or butter. In a large skillet over medium heat, cook the breakfast sausage until browned and fully cooked, breaking it into small pieces while cooking. Drain any extra fat and set aside.
2. Mix Eggs and Ingredients:
In a large bowl, whisk together the eggs, whole milk, salt, black pepper, garlic powder, and onion powder until everything is well blended. Stir in the cooked sausage and 1 ½ cups of shredded cheddar cheese.
3. Assemble and Bake:
Pour the egg and sausage mixture into the prepared baking dish, spreading it evenly. Sprinkle the remaining ½ cup of shredded cheddar cheese over the top. Bake uncovered for 30 to 40 minutes, or until the eggs are set and the top is golden and slightly crispy.
4. Serve and Enjoy:
Remove from the oven and let it cool for a few minutes. If desired, sprinkle dried parsley flakes on top for a bit of color and freshness. Cut into squares and serve warm, great alongside fresh fruit or toast for a complete meal.
Can I Use Frozen Sausage for This Casserole?
Yes, you can! Just make sure to fully thaw the sausage before cooking to ensure it browns evenly and cooks through properly. Thaw it overnight in the fridge or use the defrost setting on your microwave.
Can I Prepare This Casserole Ahead of Time?
Absolutely! You can assemble the casserole the night before, cover it tightly, and refrigerate. In the morning, bake it as directed, adding a few extra minutes to the baking time if it’s cold from the fridge.
How Should I Store Leftovers?
Store leftovers in an airtight container in the fridge for up to 3 days. To reheat, warm gently in the microwave or oven until hot throughout. Avoid reheating multiple times to maintain quality and safety.
Can I Add Vegetables to This Recipe?
Definitely! Chopped bell peppers, spinach, or onions work well added to the egg mixture before baking. Just sauté harder vegetables like peppers or onions first for best texture and flavor.
