Ingredients

Eggs- I use large eggs for this.

Baking Powder- This helps fluff the casserole when baking.

Cheese- I like using white cheddar or jack cheese but regular cheddar is delicious to use as well.

Breakfast Sausage- I like to use a mild breakfast sausage but you can also add a kick

Onion- I use diced yellow onion but white onion will also work.

Potato- I use russet potatoes to make this homemade breakfast casserole. Peel the potato before boiling it.

Salt- I use sea salt but table salt will work fine.

Milk- I use whole milk or 2% for this casserole.

What You Will Need To Make It

1 tsp baking powder

2 cups jack cheese

1 lb sausage

1 large russet potato

1/2 yellow onion

1 tsp sea salt

6 eggs

2 cups of milk

Directions

Begin by peeling and then boiling one large potato in a small saucepan. Boil until just done but not falling apart. While the potato boils, begin browning the sausage. Dice the onion and add it to the skillet. When the sausage is browned, remove it from the heat, strain off excess oil, and set it aside.

In a separate bowl, crack the eggs, and add the milk, salt, and baking powder. Whisk until combined.

Cut the potato into cubed pieces and then add them to a bowl with the cheese, sausage, and egg mixture. Stir to combine.

Pour mixture into an awaiting baking dish. Cover the baking dish with a piece of foil. Bake covered at 350℉ for 45 minutes.

Then remove the foil and continue baking for another 10-15 minutes or until the breakfast casserole is bubbly and golden.

Cooking Notes

Breakfast sausage tends to have a lot of fat when cooked, it is a good idea to strain off the excess grease before adding it to the casserole.
I use ground breakfast sausage but you can spice it up by using a spicy ground sausage.
To make it this Homemade Breakfast Casserole even quicker you can use frozen potatoes. To do, use half a 15 oz bag for this recipe.

What to Serve with a Breakfast Casserole

Serve with a bowl of fresh fruit for a bit of lightness to the meal
I like to serve this Homemade Breakfast Casserole with a side of salsa
If serving at a brunch or gathering, a great option to pair this breakfast casserole with is a Puff Pancake. Creating a sweet and salty combination that works well for groups.
Toast and jam are always a favorite at the breakfast table.

Variations

This Homemade Breakfast Casserole is versatile as it is delicious. Here are a few variations to try.
Add fresh spinach and mushrooms
Try it with bell peppers either green, red or orange
Add a spicy sausage as opposed to the standard breakfast sausage for a kick
Cheeses are another great way to switch things up. Use sharp cheddar or mozzarella cheese
Add bacon alongside the sausage or swap the sausage out altogether

Substitutions

Meat- To make things leaner you can use turkey sausage or sub the sausage entirely and use ham or bacon
Milk- You can use half and half for this recipe if you don’t have milk on hand
Cheese- Cheese is one of the easiest substitutions to make. Use yellow cheddar, sharp cheddar, mozzarella or your favorite cheese to sub out the jack cheese
Potato- You can use any kind of potato for this recipe. But be sure to use enough since red potatoes are typically small in size. You want 7.5 oz or about 2 cups of diced potatoes for this. You can also use frozen potatoes for this recipe.
Onion- You can leave the onion out altogether or use red, white or even green onions.

Breakfast Casserole Tips

To Make Ahead- You can make this ahead of time by putting it together the night before and baking it in the morning
To Store- Cover and place in the fridge for up to 3 days.
To Reheat-This breakfast casserole is great reheated in the oven at 350℉ or you can place in the microwave.
To Freeze- Homemade Breakfast Casserole freezes well. Simply bake as directed then allow to cool completely before placing an air-tight lid on and storing in the freezer. To reheat through, place in a 350℉ for about 25 minutes.
