How to make this Sausage Egg Casserole

See the full recipe below.

1. Preheat the oven to 400℉. Spray a 9×13 or large casserole dish of similar size with non-stick cooking spray.
2. Add the hash browns to the prepared baking dish. Pour the melted butter over the hash browns and toss to coat. Spread the hash brown out and place in the oven. Bake for 35-40 minutes or until the hash browns start to crisp – the edges start to turn golden brown. 
3. Meanwhile, on medium high heat, brown the ground sausage in a pan or large skillet. When sausage is partially cooked through, add the pepper and onions to the skillet and continue to cook until sausage is no longer pink. Drain liquid if it’s in excess. Set aside.
4. Next, in a large bowl, whisk together eggs, cheese, milk of choice, yogurt, salt, and pepper.
5. When the hash browns are done, remove from the oven and top evenly with the sausage, peppers, and onions.
6. Pour the egg mixture over the contents in the baking dish. 
7. Bake for 35-45 minutes or until the center is cooked through. Cover with foil if the edges start to get too brown. Baking time will depend on type and size of dish used. Start checking the egg bake for doneness at the 30 minute mark.
8. Store leftovers in an airtight container in the refrigerator for up to 4 days or freezer for up to 3 months. 

Overnight Breakfast Casserole option

It seems like we all need a little more sleep so you will love that fact that this recipe can be made ahead. No need to get up extra early to get breakfast on the table! The evening before you plan to make this Sausage Egg Bake with Hash Browns, simply complete all of the steps in the instructions up to the point of putting the egg bake in the oven.

Here are a couple of helpful tips for making this recipe ahead so that all you have to do is bake it and enjoy in the morning.

• After the hash browns come out of the oven and the sausage mixture is added, make sure to allow everything to cool before adding the eggs. If you add the eggs and the hash brown and sausage are too hot, the eggs will start to bake.
• To ensure everything is cool enough, you could also wait to pour the eggs into the dish until just before baking. Store the egg mixture, covered, in the fridge overnight. When ready to make the egg bake, simply pour the egg mixture over the hash browns and sausage and bake.
• Before baking, remove the egg bake from the refrigerator and let it sit at room temperature while the oven is preheating.

How to store Sausage Egg Bake

Store leftover egg bake in an airtight container in the refrigerator for up to 4 days or freeze for up to 3 months.To reheat, microwave the egg bake (thawed, if frozen) for 1 1/2 – 2 minutes or until center is hot. If freezing, we like to freeze the egg bake in individual servings so that you can reheat exactly the number of servings that you need.
