A good casserole is all about layering the right ingredients. Here’s what you’ll need to get that perfect balance of texture and flavor.
Main Ingredients
- Eggs
- Breakfast sausage (mild, spicy, chicken, or turkey)
- Milk or half-and-half
- Shredded cheese (cheddar, mozzarella, pepper jack, or a blend)
- Bread cubes or frozen hash browns
- Salt and black pepper
- Optional: onions, garlic, mushrooms, spinach, bell peppers
Why These Ingredients Work Together
Each ingredient plays a role, and when they come together, you get that classic, hearty breakfast flavor:
- Eggs hold everything together and give you a custard-like base.
- Sausage adds savory richness and a boost of protein.

This combination keeps the casserole soft in the center with a golden, irresistible top.
How to Make Sausage and Egg Casserole
Once your ingredients are prepped, the process is straightforward. Here’s how to build a casserole that comes out perfectly every time.
Cook and Crumble the Sausage
Brown the sausage in a skillet until fully cooked. Break it apart into small pieces so every bite is evenly flavored. If you’re adding onions or garlic, sauté them in the drippings for an extra layer of flavor.
Build the Base Layer
Grease a baking dish, then add your bread cubes or hash browns. Spread the cooked sausage over the top.
If you’re adding veggies—like spinach, peppers, or mushrooms—now’s the time to layer them in.
Mix the Egg Mixture
In a large bowl, whisk together:
- Eggs
- Milk or half-and-half
- Salt
- Black pepper
- Optional seasonings (paprika, garlic powder, chili flakes)
Pour the mixture evenly over the sausage layer. Make sure it sinks down into the bread so every bite is soft and flavorful.
Add Cheese
Sprinkle shredded cheese over the top. You can go light for a subtle layer or heavy if you want that gooey, melty finish.
Bake Until Golden
Bake at 350°F (180°C) for 40–50 minutes, or until the center is set and the edges turn a warm golden color.
Let it rest for a few minutes before serving—this helps the layers settle so each slice stays neat.
Tips for Making the Best Sausage and Egg Casserole
You can make this casserole your own with a few small tweaks. Here are tips that help you get the most flavor out of every ingredient:
- Use day-old bread—it absorbs the egg mixture better.
- Swap pork sausage for turkey sausage if you prefer something lighter.
- Add a touch of paprika or dry mustard for deeper flavor.
- Mix in spinach or bell peppers to add freshness and color.
- For a richer casserole, replace milk with half-and-half.
- If you want a little heat, use spicy sausage or pepper jack cheese.
These small choices allow you to tailor the casserole to your taste. For another hearty, make-ahead-friendly recipe, try my loaded baked potato soup, perfect for busy weeks.

Yes, both work well and give you a lighter version of the casserole.

You can safely store it for up to 4 days.
