The Core Ingredients You’ll Need
The beauty of this sausage and egg casserole lies in its simple, accessible ingredients. Here’s what you’ll need to create this breakfast masterpiece:
- Pork Sausage: One pound of ground pork sausage provides the savory, hearty base.
- Eggs: A dozen large eggs create the rich, fluffy custard that holds everything together.
- Milk: Whole milk is recommended for the creamiest texture, but 2% works well too.
- Bread: Day-old white or sourdough bread, cut into cubes, absorbs the egg mixture perfectly.
- Cheddar Cheese: Sharp cheddar cheese adds a delicious, tangy flavor. Feel free to use a mix of your favorite cheeses.
- Onion & Garlic: These aromatics build a deep flavor foundation.
- Seasoning: A simple mix of dry mustard, salt, and black pepper enhances all the flavors.
Choosing Your Sausage
The type of sausage you choose can transform this dish. While classic pork sausage is always a winner, you could use spicy Italian sausage for a kick, or even turkey sausage for a lighter option. Just be sure to cook it thoroughly and drain any excess grease before adding it to the casserole.
The Best Bread for Casserole
Stale, day-old bread is essential for preventing a soggy casserole. A sturdy bread like sourdough, challah, or a simple white loaf works best. The dry bread cubes act like a sponge, soaking up the egg mixture without falling apart, which is the secret to the perfect consistency.
How to Make Sausage and Egg Casserole (Step-by-Step)
Making this casserole is as easy as prep, assemble, and bake. Follow these simple steps for guaranteed success.

- Cook the Sausage: In a large skillet, cook the ground sausage over medium-high heat until browned. Add the chopped onion and garlic and cook for another few minutes until softened. Drain off any excess grease.
- Prepare the Base: Spread the cubed bread evenly in the bottom of a greased 9×13 inch baking dish. Sprinkle the cooked sausage mixture over the bread, followed by half of the shredded cheese.
- Mix the Custard: In a large bowl, whisk together the eggs, milk, dry mustard, salt, and pepper until well combined.
- Assemble the Casserole: Pour the egg mixture evenly over the bread and sausage layers. Sprinkle the remaining cheese on top.
- Bake or Chill: At this point, you can cover and refrigerate the casserole overnight or bake it right away. To bake, preheat your oven to 350°F (175°C) and bake uncovered for 45-55 minutes, or until the center is set and the top is golden brown.
Pro Tips for the Perfect Texture
Want to ensure your sausage and egg casserole is absolutely perfect? Follow these simple tips:
- Use Day-Old Bread: As mentioned, dry bread is crucial. If your bread is fresh, you can toast the cubes in the oven for about 10-15 minutes at 300°F (150°C) to dry them out.
- Don’t Overmix: Whisk the egg mixture just until combined. Overmixing can make the eggs tough.
- Let It Rest: After baking, let the casserole rest for at least 10 minutes before slicing. This allows it to set completely, making it easier to serve. This is a great tip for many baked dishes, including a deliciously creamy baked mac and cheese.
Fun Variations to Try
This recipe is a fantastic starting point for creativity. Try one of these delicious variations:
- Add Veggies: Sautéed bell peppers, mushrooms, or spinach make great additions. Just be sure to cook them and drain any excess liquid before adding them to the casserole.
- Different Cheeses: Swap the cheddar for Monterey Jack, Gruyere, or a spicy pepper jack for a different flavor profile.
- Hash Brown Base: For a heartier dish, replace the bread with a layer of cooked hash browns, similar to this sausage and hash brown casserole.
