Easy Sausage and Egg Casserole
Ingredients
Equipment
Method
- Preheat your oven to 350°F (175°C). Generously grease a 9×13-inch baking dish with cooking spray or butter, ensuring all corners and sides are well coated to prevent sticking.
- Heat a large skillet over medium heat. Add breakfast sausage and break it apart with a wooden spoon or spatula into bite-sized crumbles. Cook for 8-10 minutes, stirring occasionally, until fully browned with no pink remaining and fat has rendered out.
- Add diced onion to the sausage during the last 3-4 minutes of cooking, allowing it to soften and become translucent. The onion should be tender but not mushy.
- Drain excess grease from the sausage mixture by transferring to a colander lined with paper towels, or carefully tilt the pan to pour off fat. This prevents the casserole from becoming greasy.
- If using frozen hash browns, ensure they’re completely thawed. Squeeze out any excess moisture using paper towels or a clean kitchen towel. Spread hash browns in an even layer across the bottom of your prepared baking dish.
- Scatter the cooked sausage and onion mixture evenly over the hash brown layer, distributing it throughout the dish to ensure every serving contains sausage.
- Sprinkle 1½ cups of shredded cheddar cheese over the sausage layer, reserving the remaining ½ cup for topping later.
- In a large mixing bowl, crack all 10 eggs and whisk vigorously for 30-45 seconds until completely combined and slightly frothy. This incorporates air creating a fluffier texture.
- Add milk, salt, pepper, dry mustard, and garlic powder to the whisked eggs. Whisk again for 20-30 seconds until all seasonings are fully incorporated and the mixture is uniform in color.
- Pour the egg custard mixture slowly and evenly over the entire casserole, ensuring it seeps into all layers and reaches the corners. The liquid should cover most of the ingredients.
- Use a spatula to gently press down on the ingredients, helping the egg mixture penetrate all layers. This ensures even cooking and prevents dry spots.

- Cover the baking dish tightly with aluminum foil to trap moisture and prevent excessive browning during the initial baking phase.
