Easy Sausage and Egg Casserole is a hearty breakfast or brunch dish that brings together fluffy eggs, savory sausage, and melty cheese in a cozy baked dish. It’s all about simple ingredients coming together into a warm and comforting meal that feels like a big hug on a plate.
I love making this casserole when I need something quick but filling for a group, especially on weekend mornings. What’s great is that you can prepare it ahead of time and just pop it in the oven when you’re ready. I find that the combo of sausage and eggs is one everyone loves, and the cheese adds just the right touch to bring it all together.
My favorite way to serve this casserole is with a side of fresh fruit or warm toast. It’s perfect for sitting down with family or friends and sharing a relaxed morning meal. If you’re ever in a rush but want something homemade and satisfying, this casserole has got you covered without any fuss.
Key Ingredients & Substitutions
Breakfast Sausage: This adds the main savory flavor. Use mild or spicy depending on your mood. For a lighter option, ground turkey sausage or plant-based sausage works well.
Eggs: Eggs bind the casserole and make it fluffy. If you want, swap some eggs for egg whites to reduce fat but keep the protein.
Milk or Half-and-Half: Milk makes the casserole creamy, half-and-half gives extra richness. Use any milk you prefer—dairy or unsweetened plant milk like almond or oat.
Bread: White bread soaks up the egg mixture well. Day-old or lightly toasted bread prevents sogginess. Try whole wheat or gluten-free bread if needed.
Cheddar Cheese: Cheddar melts nicely and adds flavor. You can substitute with Monterey Jack, mozzarella, or a cheese blend you enjoy.
How Do I Get the Perfect Texture Without a Soggy Casserole?
The key is making sure the bread soaks up the egg mixture but doesn’t get mushy. Here’s how I do it:
- Use day-old or lightly toasted bread to help it hold together better.
- Stir the bread gently with the egg mixture and sausage so everything is evenly coated.
- Don’t cover the casserole when baking; baking uncovered lets the top crisp up nicely.
- Let the casserole cool for a few minutes after baking so it sets and slices clean.
Following these steps gives you a fluffy, tender inside with a lightly golden, slightly crispy top—just right for serving!
Equipment You’ll Need
- 9×13 inch baking dish – perfect size to cook the casserole evenly and serve several people.
- Skillet or frying pan – you’ll cook the sausage here; a non-stick one makes cleanup easier.
- Large mixing bowl – great to whisk eggs and mix all ingredients without spills.
- Whisk – helps blend eggs and milk smoothly for a creamy texture.
- Spatula or wooden spoon – useful for breaking up sausage and folding ingredients together.
Flavor Variations & Add-Ins
- Swap breakfast sausage for cooked bacon or diced ham for a different, smoky flavor.
- Add diced bell peppers or chopped spinach for some fresh veggies and extra color.
- Use pepper jack cheese instead of cheddar if you like a spicier, zesty kick.
- Stir in diced mushrooms for an earthy touch that pairs well with sausage and eggs.
Easy Sausage and Egg Casserole
Ingredients You’ll Need:
- 1 pound breakfast sausage (mild or spicy, according to preference)
- 8 large eggs
- 2 cups whole milk or half-and-half
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 4 cups cubed white bread (day-old or lightly toasted)
- 2 cups shredded cheddar cheese
- 1 teaspoon dried parsley (optional, for garnish)
- Butter or non-stick spray (for greasing the baking dish)
How Much Time Will You Need?
You’ll spend about 15 minutes preparing the sausage and mixing ingredients, then bake the casserole for 40-45 minutes. Add a few minutes afterward to let it cool slightly before slicing and serving. In total, plan for about 1 hour from start to finish.
Step-by-Step Instructions:
1. Prepare the Oven and Baking Dish:
Preheat your oven to 350°F (175°C). Lightly grease a 9×13 inch baking dish with butter or non-stick spray to prevent sticking.
2. Cook the Sausage:
Heat a skillet over medium heat. Add the breakfast sausage and break it up with a spatula. Cook until it’s browned and no pink remains, about 5-7 minutes. Drain any excess grease and set the sausage aside.
3. Mix Eggs and Ingredients:
In a large bowl, whisk together the eggs, milk (or half-and-half), salt, and pepper until smooth. Add the cubed bread, cooked sausage, and shredded cheddar cheese. Stir gently to combine, making sure the bread soaks up the egg mixture evenly.
4. Bake the Casserole:
Pour the mixture into the greased baking dish and spread it out evenly. If you like, sprinkle dried parsley on top for a touch of color. Bake uncovered for 40-45 minutes, or until the casserole is set and the top is golden brown. You can test doneness by inserting a knife in the center — it should come out clean.
5. Cool and Serve:
Allow the casserole to cool for about 5 minutes before cutting into slices. This helps it set and makes serving easier. Enjoy warm with fresh fruit or a light salad for a satisfying breakfast or brunch.
Can I Use Frozen Sausage for This Casserole?
Yes, you can use frozen sausage, but make sure to fully thaw it in the refrigerator overnight before cooking. This ensures even cooking and better texture in the casserole.
Can I Prepare This Casserole the Night Before?
Absolutely! Assemble the casserole, cover it tightly with plastic wrap or foil, and refrigerate overnight. Bake it the next morning, adding a few extra minutes to the baking time if needed.
How Should I Store Leftovers?
Store any leftover casserole in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave until warmed through.
Can I Substitute the Bread or Cheese?
Yes! Use whole wheat, gluten-free, or your favorite bread instead of white. For cheese, feel free to swap cheddar for mozzarella, pepper jack, or a cheese blend to suit your taste.
