How to Make Sausage Egg and Cheese Casserole
Making this Sausage Egg and Cheese casserole is simple and straightforward. Just follow each step, and you will have a perfect bake every time.
Cook the Sausage and Onion
First, heat a skillet over medium heat. Then cook the sausage, breaking it into crumbles as it browns. Next, mix in the dried onion and cook until fragrant.
Prepare the Egg Mixture
Meanwhile, crack the eggs into a large bowl. Whisk them well, then add milk, salt, and pepper. Continue mixing until smooth and fully combined.
Layer the Ingredients
Next, preheat your oven to 350°F. Grease a 9×13 baking dish. Then spread about three quarters of the sausage evenly on the bottom. After that, sprinkle half of the cheese on top.
Pour the egg mixture evenly over everything.
Bake Until Set
Place the dish in the oven and bake for about 30 minutes. At this stage, the eggs should look mostly set but still slightly soft in the center.
Add Final Toppings and Finish Baking
Remove the dish from the oven. Then add the remaining sausage and cheese on top. Return it to the oven and bake for another 10 to 15 minutes until fully set.

Rest, Slice, and Serve
Finally, let the casserole rest for at least 5 minutes. Then slice and serve warm for the best texture.
Tips for the Best Texture and Flavor
Small adjustments can make your Sausage Egg and Cheese casserole even better.
How to Keep Eggs Soft and Fluffy
Always whisk the eggs well before baking. Also, adding milk helps create a softer texture. As a result, the casserole stays light instead of dense.
Choosing the Right Cheese
Sharp cheddar adds bold flavor. However, you can mix cheeses for variety. For example, mozzarella makes it extra creamy.
Avoiding Overbaking
Keep an eye on the oven. If you bake too long, the eggs may turn rubbery. So, remove it once the center is just set.
